The main differences between Xiaomi Mi Band 3 and Mi Band 2

On May 31, 2018, Xiaomi officially released two versions of the Mi Band 3, standard and with NFC. Currently, the new fitness bracelet is sold at a price of 50, while the price of Mi Band 2 has dropped to 24. A reasonable question arises: does it make sense to overpay for Mi Band 3? In this article, I will talk in detail about the eight innovations that the novelty boasts.

Comparison of Mi Band 2 and Mi Band 3

1: Mi Band 3 got a large display

Since the screens in such bracelets are relatively small, everyone took its increase well. The new Xiaomi Mi Band 3 comes with a larger and better display than its predecessor. It uses a 0.70-inch OLED screen with a resolution of 128 x 80 pixels and a density of 193 PPI. It can display up to 24 high resolution large Chinese characters.

Unfortunately, at the time of writing, there is no support for Russian characters, but it will certainly appear a little later. The screen is also much taller. Thanks to the use of new high-performance chips, after increasing the resolution, the overall brightness of the display did not decrease, and the power consumption remained at the same level. The autonomy of Mi Band 3 is approximately 20 days in active use.

2: A new way to control the fitness bracelet

The screen of Xiaomi Mi Band 3 is touch-sensitive and very sensitive, it will allow you to quickly switch between the displayed content. The top panel of the bracelet is covered with anti-reflective glass with anti-fingerprint protection. The manufacturer claims increased wear resistance of the bracelet capsule, as well as higher image clarity compared to Mi Band 2.

3: With Mi Band 3 you can take a shower and even dive

Many users still do not understand the meaning of water resistance standards, we will try to explain the difference between Xiaomi Mi Band 2 and Mi Band 3 waterproof in simple words. The Mi Band 2 is IP67 certified which means it is splash and dust resistant. You can wear it while washing dishes, walking in the rain, or even doing laundry, but nothing more. You can’t shower or use it on the water with the bracelet, although in reality many do not remove it before water procedures and the bracelet remains in service. In general, Mi Band 2 is well protected from water.

As for the Xiaomi Mi Band 3, its water resistance standard is 5 ATM, which means that it is not afraid of diving under water up to 1 meter deep. It can be used for swimming and surfing, but serious diving is out of the question. The fitness bracelet can be left on while taking a shower, but no more.

As you can see, the difference between the two bracelets is quite large, and if you often deal with water, we recommend looking towards the third revision of the Mi Band. With it, you will definitely be sure that the bracelet will not fail at the most inopportune moment.

4: Display real-time indicators

Mi Band 3 has an important feature for athletes. When you switch to one of the sports modes (five types of running, riding or walking), Mi Band 3 will display on the screen the main data on the progress of your workout in real time. And if the indicators of your body exceed the specified values, the bracelet will notify you about this with an alarm.

5: New way notifications work

Xiaomi Mi Band 3 received important changes in the notification system. Now the bracelet has two types of reminders. The first includes notifications of missed calls, SMS, notifications from applications, calendar events and others. The second type is offline reminders, they are set through the application and will be delivered directly to your bracelet at the appointed time, regardless of whether your smartphone was nearby at that moment or not.

6: Mi Band 3 screen shows all information

Mi Band 3 displays all the most important information on the screen: current time, steps, heart rate and calories burned. In addition, you can turn on the display of sleep data and other information you need. Thanks to this innovation, it is not necessary to open the application on your smartphone to get statistical data about your body. It is enough to swipe your finger on the screen of the bracelet a couple of times.

7: Added three-day weather forecast

The new fitness bracelet has learned to show the weather forecast for today and the next two days. It will let you know if the weather is favorable for outdoor activities. In some cases, it can be very convenient to view the forecast without taking your smartphone out of your The new feature will be especially useful for tourists and adventurers.

8: The bracelet has become more comfortable to wear

The base of the new fitness bracelet is made of thermoplastic elastomer, while the part that has contact with the skin is made of a softer material that is friendly to the skin. One of the processing steps is freezing the strap with liquid nitrogen to shape it around the wrist, making it more comfortable to wear. We also note that this time the company produces a bracelet in three colors: graphite black, hot orange and blue.

The same person who constantly resents the lack of USB Type-C in new Xiaomi gadgets. I joke completely unfunny jokes and make mistakes in the texts. I love green apples.

The main differences between Xiaomi Mi Band 3 and Mi Band 2

At the end of May, Xiaomi presented an update to the Mi Band 3 line, while creating a basic version and equipped with NFC technology. Today, the most current variation can be purchased for 35, and the cost of Mi Band 2 is up to 24, so many are interested in the need to purchase a new generation solution.

In comparing devices, it is necessary to present 8 main differences that distinguish the third modification.

Comparison of Mi Band 2 and Mi Band 3

1: Mi Band 3 got a large display

Since the characteristics of the workspace in wearable paraphernalia are usually small, the manufacturer’s fans reacted positively to the increase in the screen, so the updated version has the ability to expand the functionality. In practice, a 0.70-inch OLED matrix with a dot density of 12880 is used, due to which 24 large Chinese characters can be displayed. The models for the domestic market do not have a Russified interface, so it is desirable to have all the latest updates. Despite the increase in the area for displaying content, the installation of productive chips allows you to keep the energy consumption indicators at a low level with an identical degree of brightness. Battery life is approximately 20 days with frequent use.

2: A new way to control the fitness bracelet

Since Mi Band 3 uses the touch navigation technique, all manipulations can be carried out by the user directly through touch. The glass surface on the front panel is complemented by an oleophobic coating to protect against scratches or fingerprints. The company claims the presence of improved resistance to damage and wear, as well as increased detail compared to Mi Band 2.

3: With Mi Band 3 you can take a shower and even dive

Many modern users are not aware of the specific meaning of security standards, so xiaomium.ru offers you to read a simple summary of the values ​​\u200b\u200bof similar parameters that are presented in Xiaomi bracelets of the current and past generation. The tracker’s second-generation certification demonstrates IP67 for dust and drip resistance, so removal during dishwashing or rain is not required at all. Despite the undesirability of using the device under water, many owners do not consider it necessary to put the device away before swimming, after which the tracker is fully operational. In fact, effective reliability is achieved.

Regarding the Mi Band 3 generation, 5ATM impermeability is guaranteed, due to which diving to a maximum depth of 50 meters is possible. Subject to the established standards, the device can be used for certain types of water sports, diving, and swimming. Accordingly, there is a significant difference between the two generations of the device, so if you need frequent contact with liquid, it is recommended to prefer the modification of Mi Band 3. The manufacturer Xiaomi guarantees the full protection of the bracelet from various adverse situations.

4: Display real-time indicators

The tracker has an essential option for sports, as when moving between the available modes, such as running or riding, through the display you can view the main information in relation to the progress of exercises in real time. At the same time, exceeding a certain safe state is accompanied by appropriate device notifications, signaling an alarm.

5: New way notifications work

The Mi Band 3 model shows significant innovations in the messaging system, as there are two variations, one of which contains missed calls, SMS, news of installed programs, and calendar reminders. Another type does not require constant monitoring of the mobile device, since it is set through the application and displays on the bracelet all the information in a specific selected period.

6: Mi Band 3 screen shows all information

The gadget provides all the most important data on the display, such as the current time, distance traveled, heart rate and calories burned. At the same time, it is possible to view information about the quality and productivity of sleep and other results of body monitoring. Due to such innovations, it is not necessary to regularly check the reporting through a proprietary application with statistics display, since for verification it is required to use only the device interface.

7: Added three-day weather forecast

The third generation of the tracker allows you to synchronize climate information for the current and subsequent days, so you can make sure that you have the right conditions for outdoor training. During exercise, using the phone can be uncomfortable, so the new option is most desirable for simplifying activities and tourist travel.

8: The bracelet has become more comfortable to wear

The main part of the design of Mi Band 3 is represented by a hypoallergenic TPE material, while a soft base is used in the area of ​​​​contact with the wrist, which does not cause inconvenience. Another stage of production is represented by the exposure of the strap to liquid nitrogen to shape the part of the hand, causing the lines and curves to follow naturally. Additionally, it is worth noting the variety of colors, since blue, orange and black are available.

Mi Band 3 review, specifications, photos and price

On May 31, at the anniversary presentation of the Chinese company, the Xiaomi Mi Band 3 fitness bracelet was officially presented. I wonder what are the advantages of the third generation of smart gadgets, and what are the main differences from Mi Band 2.

You can see how the presentation was held in Shenzhen in this article: https://xiaomishka.ru/Xiaomi-Mi-8-prezentatsiya-segodnya. In addition, the site already has a review of Xiaomi Mi 8.

Xiaomi Mi Band 3

The third generation of Xiaomi smart gadgets for active lifestyle lovers is finally presented. The release of Mi Band 3 was preceded by a list of rumors and news that discussed the possible functions of the bracelet. But only, now that Mi Band 3 has been officially released and its specification has been confirmed, you can make a full review of the fitness bracelet.

What’s Included?

The equipment of the novelty is standard and differs little from the previous model.

Full unboxing in photos for clarity.

Only the packaging has changed. The new bracelet comes with a transparent top cover. Looks fresh and interesting.

Design and appearance

Mi Band 3 is equipped with an OLED display (like its predecessor). The screen has a diagonal of 0.78 inches with a resolution of 128 x 80 pixels. Compared to Mi Band 2, the screen of the novelty has increased by 0.36 inches (against the diagonal of 0.42 inches, which was earlier).

Useful Features

Unlike Mi Band 2, Mi Band 3 has a touch screen. Therefore, the developers have finalized the notification panel. Now, all types of event notifications text messages, caller ID or the ability to make a call will be displayed there.

Other characteristics

The Mi Band 3 bracelet is made of soft pleasant material. The material is hypoallergenic, so it does not cause irritation in people with skin problems. The bracelet is available in three colors to choose from:

The capsule of the device features a waterproof design. If the specifications of Mi Band 1 and 2 indicated only the IP67 protection class, then the third generation has water resistance (5 ATM, up to 50 meters).

The new fitness bracelet has a 110 mAh battery, thanks to which the average battery life of Mi Band 3 is up to 20 days from a single charge. According to usage statistics, and given the cost, this is a good result.

The communication module uses Bluetooth 4.2 with LE (Bluetooth Low Energy) technology.

What does 5 ATM mean (50 m)?

What does the water resistance of 5 ATM indicated in the device specification mean in practice:

The capsule of the device can withstand the static pressure of a 50-meter water column (5 atmospheres).

In other words, you cannot dive to a depth of 50 meters with a bracelet on your hand. It is not recommended even to a depth of 10 meters. for this, a water resistance of at least 200 ATM must be indicated.

With a bracelet on your hand, you can take a shower, get caught in the rain, or wash your hands without removing the gadget from your wrist.

You can swim in the pool or fresh water without worrying that moisture will get inside the device.

It is not recommended to swim in sea water and reservoirs with high levels of salt.

Not enough GPS!

The Mi Band specification lacks GPS. This component would determine not only our location, but would also show the distance traveled more accurately. Many users in their reviews have already noted this nuance as a drawback, or a small minus in 2018.

The argument in favor of the lack of GPS is the affordable retail price of Mi Band 3, which can be called low compared to competitors.

Mi Band 3 NFC

Does Mi Band 3 have NFC? Even during the presentation, this question worried the audience the most. Lei Jun spoke for a long time about the advantages and merits of the novelty, keeping the intrigue. Until the coveted slide finally appeared on the screen, which showed how a user makes a contactless payment using his Xiaomi fitness bracelet.

Therefore, if the presence of NFC is important to you, be careful when buying Mi Band 3 on AliExpress and carefully read the product description, since both versions are similar in appearance, but have different prices.

Xiaomi Mi Band 3 specifications

Detailed specification, according to information from the official website of Xiaomi.


The price of Mi Band 3 NFC (that is, the version with the NFC module and the ability to make contactless payments) is 199 yuan.

This is the price of Mi Band 3 at the start of sales in China. In Russia, in official stores, the bracelet will cost more. This has always been the case, so the price increase is expected.

When will appear in Russia?

Xiaomi officials clarified that the release date for Mi Band 3 in Russia is July-August 2018. According to preliminary information, the fitness bracelet is planned to be presented together with the global version of Xiaomi Mi 8.

A version of the bracelet without NFC will be presented in Russia.

Differences from Mi Band 2

The main differences relate to the display size, screen resolution, new features, Bluetooth version, larger battery, water resistance, and the presence of an NFC module.

The photo shows how the capsules differ in size, but visually in the bracelet itself the difference is not so noticeable.

Dear readers, a more detailed comparison of Mi Bands 2 and 3 can be found in this comparative review:

You will also learn about the main differences from Mi Band 2, and you can decide for yourself in favor of buying a particular model.

Hello dear friends! My name is Mikhail Xiaominko, I am a fan of Xiaomi technology, gadgets and smartphones. Having access to information, I try to provide interesting and high-quality content for Xiaomi readers. Sharing the latest news and exclusive content.

Thanks for the great review and great photos! I liked the bracelet, although it seems too big, but now I will definitely take it.

Thanks for the review. I’ll wait for the start of sales.

Excellent photos and information. I took note. I liked the comparison with Mi band 2.

Class! I love when there are a lot of photos. And then the renders are not the same coat.

There is NFC, so I will buy. And it doesn’t matter what other differences he has from the deuce.

So far the Chinese have lived up to my expectations. Fitness tracker is not mega ugly. There is a choice of bracelet colors. The screen is bigger. Look at the photo where the first Mi Band still lies, so it seems like a hulk.

Again, on Xiaomishka, before everyone else, a normal review appears)) Thanks to the author. In turn, I read reviews about the presentation in the community and I think that it is incorrect to think about whether it is worth overpaying an extra 5-10 for NFC. Yes, the model can still work crookedly in Russia. But it makes sense to save a penny if the function is still useful later.

The last and penultimate photo does not quite correctly display the dimensions of the devices without a bracelet, there are capsules and the third Band is much larger than the second. But in the last photo, where they are in bracelets, they are almost the same.

So it is, visually on the hand the three is only slightly larger than the deuce.

Dear Mibendushka, come to Russia soon! I’ll buy you about four pieces. Mom, dad, and sister, but I’ll probably take two for myself, so that on both hands, and even with NFC.

Doooaaa! Contactless payments are more important for a fitness bracelet than position, speed and pace! Here are the deer! And how long have I been waiting for him, ugh, blt

At one time I wanted to buy beng2, but when I found out about the imminent release of the 3rd, I decided to wait and was honestly disappointed, yes, the screen is a little larger, well, a little more autonomous weather to find out the useful NFC feature to pay? Will it work for us? And if it does, will your hard-earned money be stolen somewhere in the flea market? In my opinion, the option that was planned earlier, with a large color screen, was IMHO better luck in Xiaomi sales with a gadget for rogues

Have you ever used NFC on a smart phone and paid at the supermarket? The banking algorithm of protection is also worth it. In order for the money to be stolen from you in the flea market, it is necessary that you lean against the bracelet specifically (like an intercom for example) for a few seconds. And then the Chinese will most likely do this whole thing through the application, and in the bracelet there is just a module that will not work without an application on your smartphone. If the craftsmen will operate some kind of skimmer in the subway, then the maximum without confirmation will be 100 rubles removed. In reality, all these schemes are being worked out by the bank to make the use convenient and safe. The main thing here is the availability of compatible equipment and the necessary modules. All this I’m leading to the fact that the good fellows that finally zanusunul this NFC, especially since it costs a penny on the hardware. And gps x.z. Xiaomi focuses on the mass consumer, trying to make the price affordable. Still, just as Mi band 2 has become the most popular, it means that sales of this model will go uphill, especially among those who are not yet familiar with a fitness bracelet and are just about to buy it. These people are not critical and are guided by the positive reviews of the majority, but they are good for the entire series of Mi bands.

I read negative reviews. The pancake differed like girls, as if we were considering a new Apple Watch. It’s not like that, it’s not like that. Here, again, they didn’t do it, but I said it !! etc. Well, what is important in the bracelet is that it sits comfortably on the arm, works for a long time without charging, the screen was normal. So that the numbers can be seen from an arm’s length. A set of standard functions that you really use in life. Not 1050 modes for all sports.

It is also important to be protected. You can swim in MB3, well, it’s cool. Went to the pool and don’t worry.

Availability of NFC? Well, I don’t use that. If I get my hands on it, I’ll buy myself a compatible smartphone. For example, in Ukraine there is a bank called Privatbank. So there are now actively these same Apple Watch and PR with support for ApplePay. Fire, of course, only these watches cost 10-11 thousand hryvnias (it turns out 24-26k rubles).

And what does the “rogue” have to do with it, you want to be fashionable and throw a lot of money down the drain, ahead is your choice. I like to spend money wisely and use gadgets that work out their value by 100%. Show-off is not the main thing, but the main thing is convenience!

Tell me please, and the strap itself, which is included. Is its color printed on the box? I would buy red, I like bright colors.

I think that in stores there will be a sticker in Russian on the back, where the color will be indicated. And so you have to learn Chinese. Because on the box itself it is not painted anywhere what color the bracelet is.

The lid of the box is transparent. You will see everything in advance)))

Xiaomi Mi band 3 vs Mi band 2: сравнительные замерыобзор!

Don’t worry, the color of the bracelet is indicated on the box.

So anu not dare to drive a barrel on my favorite bracelet!! Mi is already a whole brand in the fitness industry. In the hall, at work, in the bank, I see girls with mi bands on their hands. I’ve been using it for over a year now, I’m used to it. Really helps to achieve goals in the gym and control training. I was really looking forward to the new model. Well, I’m not so picky to reproach the developers for something. A touch screen would be handy. It’s great that the case is now waterproof. And wearing without charging for more than two weeks is also very important. Therefore, after weighing the pros and cons, if there is an opportunity, I will buy Band 3 for myself, and let the old one lie for the history of my weight loss.

How is the screen in the sun? Will anything be visible? In band2, only this is wildly infuriating

The screen shines in the sun. It uses not the best OLED display, so that the screen is readable enough in bright sunlight. But you get used to it with time.

I was looking for information about mi band 3. Finally I found something worthwhile. Thank you! Will I know when it will go on sale? It is desirable that they sell in Ukraine, I don’t want to ask my friends to take them to Moscow.

The box is cool, I remember in what cardboard boxes Xiaomi used to produce their bracelets. It’s cool that the buyer has the choice to buy with or without NFC. if you do not suffer from the need to use this function. In appearance, the capsule looks like my old mp3 player, the case also shone in the sun.

Mi Band 3 or Mi Band 2. What’s the DIFFERENCE? Should I take it? What DIFFERENCE?

Good reviewer. The main thing is that there are a lot of live photos. This is important to see how the bracelet looks in reality and not in pictures. it’s a pity that the sellers on Alik are now driving with a price of under 50 bucks. I will wait until autumn or until they sell at a normal price!

Youtube gurus said he was ugly. I looked at real photos. nothing like that, it looks quite acceptable. And the bloggers apparently snickered, or Apple sends them to other manufacturers with criticism of unreasonable drowning.

I wonder how it will work together with the LG V30?

Mi Band connects perfectly with all Android phones. If you buy an iPhone on iOS, there will also be no connection problems.

I did not like that it is very large, not suitable for a petite girl. Or fit?

Try miband2. If it sits normally, then in the bracelet itself the third model does not differ much when you put it on your hand.

Suitable for the neck) The pulse will be measured more accurately.

Can you please tell me if you can swim in salt water in it?? If I go with him to Turkey and swim in the sea, will my band break?? I know that the Mediterranean Sea is very salty, so I’m worried. (

I would not dare to swim with a bracelet in the sea. over, salt water is not fresh. And as far as I know, how water resistance tests are carried out. They do it only in ordinary running water. If you are going to swim, just take it off and there will be no problems!)

Currently only Chinese. But the developers continue to work on 100% support for the English interface, and also plan to release support for the Russian language in the global firmware.

I ordered the third Mi Band on Aliexpress and ran into the following problem. The box came ideally, everything is fine, but the Mi Band itself does not turn on. Tried to put on charging does not help. On 4pda, craftsmen recommend putting it in the freezer for a couple of hours. So I’m wondering if this really helps? I do not want to put the device itself in the refrigerator. All of a sudden, it breaks him down. Has anyone had a similar issue and how did you solve it??

Are you serious in the refrigerator?) Just put it on charge overnight, let the poor guy acclimatize and everything will be fine!!

Not in the fridge, but in the freezer. and yes! it really works)))

You can also try boiling. Personally, after the third boiling, it helped me come to life. Satisfied as a mole!

After standing on the charge all night, he still turned on. But now another trouble, the sensor practically does not react. Opened a dispute for a refund. Apparently I got some kind of marriage. Or what kind of joke I don’t know

My mibandushka came from China. Put it on charge. How do you know if it’s charging or not??

Press the button on the display, it should show a flashing battery indicator. If the icon is blinking, it means it is charging. If nothing happens, then either there is a problem with the charger, or the contacts are damaged, or they just need to be cleaned. Trite, but also important to correctly insert the capsule into the charge.

I’m wondering, those whiners who were disappointed in the fitness bracelet, why did they want to buy it? Because show-off, beautiful, everyone wears, or really for tracking: calories, steps, pulse?!

Bought in Allo. I will share my impressions. The bracelet is wonderful, works as it should. Nothing extra. But before purchasing, you need to pay attention to several inconveniences: 1. There is no support for Ukrainian. In order for the display to be correct, you will have to switch your smartphone to Russian, and this is unpleasant. In general, the developers had the opportunity, instead of not supporting the language, to automatically select at least English. Better yet, in the MiFit application, give the user the opportunity to select the desired language. 2. The MiFit application, unfortunately, cannot send the heart rate to Google Fit, which is surprising. 3. It is impossible to see something on the screen in daylight, especially on a sunny day. 4. The ability to answer a call from the device is disabled. You can either mute or drop the call. For people who wear a wireless headset under a hat, this is an unpleasant problem. 5. The name of the caller will not scroll, it’s terrible! It is impossible to understand which Alexander is calling now, although there is enough space on the screen. 6. The device does not see daytime sleep. This is generally something strange, especially for an elderly person, for example. 7. In order to switch the silent mode, you have to go deep into additional actions. Why ?! This function is much more necessary than the step counter, as for me. I really hope that all these shortcomings will be eliminated in firmware updates in the near future, and the bracelet will become really flawless!

Are you serious that the Russian language is unpleasant? Well, the review would have been written in Ukrainian completely or in fluent English. Laughing out loud. How people were brainwashed. In general, this is very sad (. Those who come to Russia and translate documents into Russian even for some reason ask to Russify the name. And thanks for the Комментарии и мнения владельцев on the bracelet, it helps to decide.

What’s inside the bracelets?

Both bracelets have a three-axis accelerometer that counts steps and a heart rate sensor. The Mi Band 3 has an improved heart rate monitor compared to the second version. This is confirmed by the ISO-10993-5/10 certificate.

The Mi Band 2 has a smaller screen, its battery is also smaller: 70 mAh versus 110 mAh for the third version. The lifespan of a single charge for both versions is about 20 days. But you need to understand that these figures are a fairly average indicator. Many claim that they do not charge the Mi Band 2 for more than a month, because they rarely turn on the display or even turn off the heart rate monitoring. The weight of the Mi Band 2 capsule is 7 grams, and the third version is one and a half grams heavier.

Both versions are dust and moisture resistant. Only for Mi Band 2, its class is designated as IP67, that is, the bracelet will withstand if it is dipped in water to a depth of 1 meter for 30 seconds. But with the third version, everything is very serious: the bracelet can withstand a pressure of 5 atmospheres! That is, you can even swim in the pool and dive with it to a depth of 50 meters without fear of damaging the Mi Band 3. And this makes the bracelet an excellent fitness tracker: now swimmers can track their workout.

Mi Band 2 communicates with the main device via Bluetooth 4.0, while Mi Band 3 works with version 4.2. This increased the speed of processing and data transfer.

In the autumn of 2018, especially for the full launch of the Mi Pay payment system, Xiaomi will release a special version of Mi Band 3. It will support the NFC protocol. It is not yet known exactly whether it will make sense outside of China, but there are rumors that they will also make friends with Google Pay. And this is very cool. It will be possible to pay in stores, even if your smartphone does not support NFC!


Mi Band 3 is not for sale yet, but it is hardly worth looking for the official Mi Band 3 with NFC.

I didn’t buy my Mi Band 1S to count steps and measure my pulse. In fact, these functions seemed useless to me. I just didn’t want to miss an important notification from or messengers. I also heard that the bracelet helps to wake up. Like, it tracks the phases of sleep and wakes you up at a certain time interval when you have a shallow sleep. Then the “smart alarm clock” function has not yet been removed from it.

So, before buying, I needed Mi Band for notifications and as an alarm clock.

Xiaomi Mi Band 1S

The bracelet performed both of these functions well. I was very pleased with this purchase. And, to be honest, during this time I have lost the habit of sound alarm clocks. The vibration of the bracelet proved to be effective!

After some time, I noticed that I try to constantly fulfill the norm in terms of the number of steps taken. I like to keep track of how much I walk per day. I like to realize that I am not the laziest person, despite my sedentary lifestyle. I realized that it was not so long to get to my girlfriend’s work. I also started hanging out with my friends more often. Just don’t tell your friends and girlfriend that this is all the bracelet makes me do.

In my Mi Band 1S, I do not have enough hours. I even thought about buying some smart ones that perform the same functions. But I did not like that many of them had problems with the Russian language and appearance. And the price. And they need to be recharged almost every day. Meanwhile, I only charge my Mi Band 10-12 times a year. And this is despite a tiny 41 mAh battery.


We always look at how the device looks first. But to say that one of the versions is prettier and the point is not to respect the readers. Everyone will decide for himself which of the two versions he likes more:

Personally, I like the third version of the bracelet more. I never liked the second generation. Although many think the opposite. And that’s ok.

The Mi Band 2 has a small 0.42-inch OLED display with a resolution of 72×40 pixels. The image on it is rather dim and difficult to see on a bright sunny day. Below the screen is a button. When pressed, the display is activated. It displays time, steps taken, distance, calories burned, the user’s heart rate, as well as a call notification. Later, it became possible to mute the sound of the ringing phone by long pressing the button.

Mi Band 3 has got a bigger OLED display. It is almost 2 times larger than the old one, its diagonal is 0.78 inches, and the resolution is 128 × 80 pixels. The button is gone now. The need for it has disappeared: the screen has become touch.

On the Mi Band 3 screen, you can view SMSes and messages from instant messengers, see who is calling you, and also reject a call. It shows the weather for the next three days and shows you your workout data in real time.

Also, the bracelet is synchronized with the calendar and reminds you of upcoming events. In addition, the bracelet can do everything the same as the second version: show the time, how many steps and km you have walked, how many calories you have burned, etc.

Both versions are sold in black only. Colored straps need to be purchased separately.

It is clear that Xiaomi will now force Mi Band 3: the second generation looks already obsolete. The functionality of both versions is not much different from each other. Personally, it seems to me that the difference between the Mi Band 2 and the stock Mi Band 3 is so insignificant that it is worth choosing solely in appearance.

But if you understand that you cannot live without NFC, then the choice becomes obvious for you. It remains only to wait for the release of the bracelet outside of China with built-in Google Pay.

Xiaomi Mi Band 3 received a more streamlined capsule design with a glossy finish and a 0.78-inch touchscreen display based on OLED technology with a resolution of 128×80 pixels. Unlike Mi Mand 2, the display of Mi Band 3 shows more useful information. For example, in standby mode, in addition to the time, the date and number of steps taken are displayed. The display can be locked to prevent accidental operation. Swipe up from the bottom to unlock. At the bottom of the capsule is an optical heart rate monitor, and the case of the novelty is now not only protected from moisture, but is designed for immersion under water to a depth of no more than 50 meters (IP67 protection class).

If we talk about functionality in general, then it is similar to Mi Band 2. Xiaomi Mi Band 3 can count steps, pulse, calories burned, show time, track sleep quality and display notifications. At the same time, each function has become more informative thanks to the use of an enlarged display with touch control. Two new features are the weather forecast and the stopwatch. Now you can reject calls by long pressing a special recess on the display.

Xiaomi Mi Band 3 Black connects via Bluetooth 4.2 interface. To set up a fitness bracelet, a proprietary Mi Fit application with an intuitive interface is offered. The Xiaomi Sports App helps you adjust your activity according to your individual needs. The 110 mAh high-capacity battery guarantees up to 20 days of battery life. Full battery charging time takes 2 hours.

The ergonomic rubber strap does not interfere with everyday use at all. This model is made in black. Also released bracelets in red and blue. Traditionally, the manufacturer will offer customers a variety of straps of different materials and colors.


The appearance of the third version of Xiaomi Mi Band is more like the very first model of the company’s fitness bracelet. Its design has more curved and convex outlines. especially in the upper part where the capsule is located. Mi Band 2, on the other hand, has a flatter outline of the same capsule, but otherwise looks quite similar to the new one. Of course, such an updated design, although it looks much more attractive than its predecessor, is also subject to wear much more. The fact is that the convex side of the capsule is much easier to scratch, while any protective films for the bracelet are not yet expected for sale. The design of the strap in both models of fitness bracelets is very similar, and with a similar clasp.

Xiaomi Mi Band 3 vs Mi Band 2: main differences

Today we will look at the main differences between the new Xiaomi Mi Band 3 and its previous counterpart. Mi Band 2, and we will try to figure out how big the difference between the two models of fitness bracelets is.

Xiaomi Mi Band 3, the new model of the sensational fitness bracelet expected by many, was presented yesterday. Not surprisingly, many comparisons of the two models immediately began to appear on the network. After reading a few articles on this subject, I tried to group all the information, and left you all the most interesting. So, what is the difference between the new product and the previous Mi Band 2? Let’s figure it out.

Now completely waterproof

The main feature of Mi Band 3 is the improved protection of its case against water penetration, now according to the IP68 standard. The bracelet withstands water pressure of 5 atmospheres, which is similar to diving 50 meters under water. Thus, Mi Band 3 became the first bracelet in the series officially suitable for a full swim. Unlike it, Mi Band 2 complies with the IP67 standard, and it is only allowed to dive to a depth of 1 meter, and when calmly in the water.


Xiaomi Mi Band 3 received a slightly larger display with a diameter of 0.78 inches, compared to 0.42 inches in its predecessor. In addition, it is monochrome, with embedded OLED technology, and a resolution of 128 x 80 pixels. It has also become touch-sensitive, and with just a swipe, the user will be able to switch between their work screens, which in turn will allow them to display even more information. The button is no longer a separate element. in the new model from Xiaomi, it is built into the glass case of the bracelet, but there is a small gap in its lower part.


The battery capacity of the new fitness bracelet has been significantly increased. up to 110mAh, against 70mAh of its predecessor, which, of course, should be important in the duration of its work. But, according to the developers, the battery life of the new bracelet will be the same as that of Mi Band 2. up to 20 days. The new filling of the bracelet will consume more charge, in particular, the battery capacity consumption will increase due to the heart rate sensor, and many other functions. Again, it is not yet entirely clear how much they will increase energy consumption, and whether it will be possible to somehow avoid all this.

Other changes

Mi Band 3 is connected to your device via Bluetooth v4.2 BLE. Along with this improvement, a feature has also been added to receive notifications from applications and when receiving an incoming call. In addition, versions of the novelty with built-in NFC technology are expected to be on sale, but all its advantages will be tied to Mi Pay. payment system available only in China.

The Xiaomi Mi Band 3 is expected to be priced at 26, which is slightly lower than when the Mi Band 2 launched. Of course, if you don’t plan to swim extensively and are content with just basic information about your daily activity, then the Mi Band 2 will still be great. show off at work. But if you are determined to upgrade, then you still need to wait, since the bracelet has not yet officially gone on sale. In addition, it is likely that its price in the first few months will be unreasonably high. Why overpay?

The answer is simple. read our instructions and get complete information on how to connect Mi Band of any generation 2, 3, 4, 5 to iPhone, set everything up and enjoy your work.

Xiaomi Mi Band 2

The bracelet belongs to the early versions, so the functionality cannot be called extensive: accounting for the distance traveled and the number of steps, a calorie counter and smart alarm functions. In addition, sleep monitoring options, a heart rate monitor and a notification center are available, allowing you to receive incoming calls and view messages.

Often, many users find themselves in a situation where the iPhone cannot find the Mi Band the first time. And this happens with any generation of a fitness bracelet. In this case, it is recommended to simply disable and re-enable Bluetooth on your smartphone.

Another common connection problem is Pair device first on the tracker screen. The solution can be found at the specified link in our detailed instructions.

Xiaomi Mi Band 5

The fitness tracker of this generation has won the interest of many owners of Android and iPhone smartphones. The device retains the functions of all previous generations, in particular the 4th version. It became possible to plan walks and trips, thanks to the built-in maps and GPS navigator, PAI indicator, and others. Of the technical characteristics, one can note an increase in the screen and improved fonts, as well as a more convenient connection of the charger. It is also useful to know how to distinguish the original Mi Band 5 from a fake.

Connection algorithm

In order for the synchronization to be successful, the bracelet must be charged at 50% or more, and the iPhone has been updated to iOS version at least 10.0.

  • Download the Mi Fit app from the App Store and turn on Bluetooth.
  • Create a personal account or log into an existing one.

Possible problems

  • The connection was successful, but the Mi Band 5 does not respond and does not display a number of functions. Charge the bracelet battery up to 90-100%, then check the functionality.
  • If the phone does not see the tracker, then the device memory may be full. Clear the cache and memory if possible, then try to connect again.
  • If there are problems with the lack of certain statistics, then check the connection to Wi-fi, Bluetooth and GPS.
  • If the notification “Perform a reset fitness bracelet” appears. then reset your settings. This is especially true if the bracelet has been in use for a long time. This solves a number of problems that could appear during updates.


The enlarged display of Mi Band 3 made it possible to significantly expand the functionality of the device. Now all data on physical activity will be more detailed, the text of messages should be displayed directly on the bracelet display, and with an incoming call, Mi Band 3 will also display the name of the subscriber. Mi Band 2, paired with the Mi Fit app, uses only icons for all this.

Even if at the start the Mi Band 3 screen can only display WeChat and QQ notifications, over time, the manufacturer itself or the authors of third-party applications will probably be able to adjust compatibility with instant messengers and social networks popular outside of China.

The Mi Band 3 also offers new widgets such as the weather forecast and reminders of upcoming events. All other features available on Mi Band 2 are preserved, including sleep monitoring, vibration alarm, unlocking the smartphone.

Sensors and communications

Both devices are equipped with a three-axis accelerometer responsible for counting steps and a heart rate sensor. The latter in the case of Mi Band 3 has a higher accuracy, confirmed by the ISO-10993-5/10 certificate.

The novelty communicates with the smartphone via Bluetooth 4.2, while the previous tracker model only supports Bluetooth 4.0. This improvement should provide an increase in the speed of data reception and transmission.

Another important difference between the novelty was the NFC chip, which will be equipped with a slightly more expensive version of the Mi Band 3. It will allow you to use the bracelet for contactless payment, however, Xiaomi did not mention support for the Google Pay service at the presentation.


It was the screen that became one of the main differences between Xiaomi Mi Band 3. It was almost doubled: 0.78 inches versus 0.42 inches for Mi Band 2. At the same time, the resolution increased proportionally: 128 × 80 pixels versus 72 × 40 for its predecessor. In addition, the display of the novelty is touch-sensitive, which allows you to control the tracker with simple swipes, and not by pressing a special button, as is the case with Mi Band 2.

It is also worth noting that the Mi Band 3 has a trendy 2.5D glass, which makes the screen panel more streamlined and rounded around the edges. The Mi Band 2 had a completely flat display. As for the matrices themselves, they are essentially the same: these are monochrome OLED panels.

Which fitness bracelet is better: the new Xiaomi Mi Band 3 or Mi Band 2

Both accessories have interchangeable straps, but the silicone bracelet from Mi Band 2 will not fit the Mi Band 3 capsule. The reason for this is not only a different form, but also its increased size. In Mi Band 2, the main module has dimensions of 40.3 × 15.7 × 10.5 mm, while the new one has 46.9 × 17.9 × 12 mm.

As for the straps themselves, the Mi Band 3 is adjustable from 155-216 mm with a total length of 247 mm. For Mi Band 2, these are 155-210 mm and 235 mm, respectively. That is, the novelty can be suitable even for those to whom the previous Xiaomi bracelet turned out to be too small.

Along with the increase in size, the total weight of the accessory has also grown significantly: 20 g versus 7 g. However, Mi Band 3 will hardly be noticeable on the wrist.

Xiaomi Mi Band 2 has an IP67 waterproof rating, which allows the device not to be afraid of rain, showers, and even short-term immersions to a depth of up to 1 m. at 50 m.


Due to the appearance of the touch screen, the power consumption of the Mi Band 3 increased noticeably, but the battery capacity increased from 70 to 110 mAh, which made it possible to maintain autonomy at the same level. The new bracelet, like Mi Band 2, works on a single charge for about 20 days. This is more than enough to not carry a power cord with you.

One of the main features of Xiaomi bracelets has always been a low price, and Mi Band 3 is no exception. The basic version of the tracker will cost 169 yuan, and the version with NFC will cost 199 yuan. For comparison: Mi Band 2 started at 149 yuan, that is, the difference is small.

As is usually the case at the start, the first Mi Band 3 on AliExpress will cost about 1.5-2 times more than the official price for China. That is, it costs at least 3,000 rubles to navigate. However, even at this price, the bracelet will probably sell like hot cakes.

Comparison of Xiaomi Mi Band 3 and Mi Band 2

At the end of spring 2018, the announcement of two versions of the Xiaomi Mi Band 3 fitness tracker, basic and with NFC support, took place. The model has become the successor to the popular Band 2, which sells for less than 20. And when choosing a “smart” bracelet, many users do not know what to do better: buy a proven second version or pay a few dollars more and purchase a new model.

Sensors and communications

Both models received a three-axis accelerometer, which contributes to a more accurate determination of the number of steps taken. Support for heart rate sensor is provided, while experts say that in the third model it is better and complies with the ISO-10993-5/10 certificate.

There is also a version of Mi Band 3 with NFC support on the market. When the manufacturer released the second version, users could not even dream of such a thing.

The presence of a sensor allows you to conveniently make contactless payments without taking your smartphone or wallet out of your

Fitness features

In terms of the number of available functions, Band 3 surpasses its predecessor. At the same time, the general training regimens are very similar. Both models have a list of basic functions:

Now in the menu of the Mi Fit program there is an option to activate the sports interface to check all statistics. It also allows you to choose the goal of the workout.

Case and strap

Two models are equipped with removable bracelets, but the strap from the second version will not fit the Band 3 capsule. This is due to the changed case shape and increased dimensions. The updated tracker has dimensions of 46.9 x 17.9 x 12 mm. The predecessor had the following dimensions 40.3 x 15.7 x 10.5 mm.

The total length of the Mi Band 3 strap is 247 mm, adjustable from 155-216 mm. The 2nd version has a 235 mm long strap and is adjustable from 155-210 mm. This means that Band 3 is suitable for those users who found the previous model too small.

Xiaomi Mi Band 2 supports the modern degree of IP67 moisture protection, which allows it to freely endure being in heavy rain, shower or immerse in water to a depth of 1 m. The successor has become even more advanced and received such waterproof parameters:

Another difference between the Xiaomi Mi Band 3 bracelet is an enlarged display, which has a diagonal of 0.78 inches and a resolution of 128 x 80 pixels. For comparison, the previous model had a screen of 0.42 inches and a resolution of 72 x 40 pixels.

Xiaomi Mi Band 3 vs Mi Band 2 — overview

The technical differences are small, but in practice they provide almost a twofold increase in the image, which allows you to compare devices like the iPhone 5 with the iPhone 10.

The Band 3’s screen is touch-sensitive, so users don’t have to move the navigation button to select the desired option. This is a useful feature that is needed for comfortable control of new modes and functions. Light swipes simplify the operation process, giving the owner a pleasure.

Along with a large screen, the new tracker received advanced integration with external Android devices.

This allows you not to be distracted once again by notifications and continue to do work or training. The predecessor had a similar option, but instead of full text, the display only showed a call or message icon.


The big difference between the fitness bracelet Mi Band 2 and Band 3 lies in the degree of water resistance. The second generation is distinguished by support for the IP67 class, which provides good protection against water.

The gadget can work freely outdoors in the rain, withstands trips to the shower and washing hands. He is also not afraid of easy diving to shallow depths.

The bracelet is not afraid of any contact with water, so you can use it when swimming in the pool, diving to a depth of more than 10 meters and walking in rainy weather. However, the model is afraid of prolonged exposure to salt water, so when relaxing on the sea, it is better to remove it from your hand.


Specifications of Xiaomi Mi Band 3 and 2 in comparison are as follows.

starting cost 169 yuan 149 yuan


However, such an innovation is justified by the presence of a large screen and advanced functionality. Therefore, when evaluating autonomy, two devices demonstrate 20 days of uninterrupted operation without recharging.

The most controversial characteristic of trackers is their cost. However, for many buyers, it becomes a key selection criterion.

At the time of the presentation, the basic version of the Mi Band 3 cost 26. For an NFC-enabled model, you would have to pay 31.

For comparison, the second generation device was sold for 23, and today it is available much cheaper.

It was created taking into account the errors and shortcomings of the previous model, therefore it is more popular. However, this does not prevent version 2 from being actively sold and finding its own audience of buyers.

The list of key advantages of Band 3 over Band 2 includes the following points:

  • Improved degree of moisture protection. Now you can dive to great depths, swim in the pool or walk in the rain without fear that the tracker will fail.
  • NFC support in separate version.
  • Larger display and increased battery capacity.
  • Extensive notification options.

So what is the best choice for daily use? In this matter, it is better to be guided by individual preferences and financial capabilities. Do not forget that the third generation of Mi Band fitness trackers will cost more than the second generation from intermediaries.

Once the Band 3 stabilize, the choice will be clear. Experts advise to wait a bit and follow the market trends. The release of the next 4th generation in international sales will reduce the cost of the 3rd.


The screen is one of the main differences between Mi Band 4 and Mi Band 3. The new generation bracelet is equipped with a 0.95-inch AMOLED color display with a resolution of 240 × 120 pixels. The tracker of the third generation is equipped with a modest OLED panel with a resolution of 128×80 with a diagonal of 0.78 inches. Thus, the screen area has increased by almost 40% and can accommodate 21 more Chinese characters. It is clear that such a screen is much more informative.

Another significant difference is the tempered glass screen protector of Xiaomi Mi Band 4, and not the most shock and scratch resistant plastic of its predecessor.

The use of a color AMOLED screen has expanded the boundaries of gadget customization. If the Mi Band 3 has only three dial options, then the Mi Band 4 allows you to choose one of 77 dial options, and if you take into account all the customization options, you get more than 380 combinations of screen settings.

Sensors and connections

The heart rate sensor for both devices is most likely the same, but the accelerometer is different. Mi Band 4 was equipped with a 6-axis accelerometer, and not 3-axis, like its predecessor. It should capture activity indicators more accurately, as well as detect new types of activity that Mi Band 3 cannot detect.

For pairing with a smartphone and exchanging data, Mi Band 4 uses a Bluetooth 5.0 module. It has a wider range, provides faster data transfer and is more energy efficient than Band 3’s Bluetooth 4.2.

As in the case of Mi Band 3, the new generation has an NFC version with support for payments via AliPay and WeChat Pay. In addition to NFC, this version is equipped with a microphone for voice assistant (Chinese voice assistant) and control of smart home devices. Unfortunately, this version of the bracelet will only be useful to users from China.

In all other respects, both bracelets are very similar. Both can measure heart rate, count steps, calories and distance, evaluate sleep, notify you of calls and messages, etc.

In terms of performance, Mi Band 4 is not much different from Mi Band 3. It is still the same silicone strap and a removable capsule with water resistance up to 50 meters. The dimensions of the gadget remain the same and, moreover, the new tracker is compatible with straps from Mi Band 3, which is very convenient.

The way to charge the battery and, accordingly, the device for charging has changed a little. In the previous three generations, the charging contacts were on the end of the capsule, in the fourth generation bracelet, the contacts moved to the back side of the tracker, but you still have to remove the capsule for charging.

With the release of Mi Band 4, the number of standard strap color options has increased: black, pink, blue, burgundy and orange. Band 3 is available in black, blue and red.

The standard version of Xiaomi Mi Band 4 in China was priced at 25, and the NFC version at 33. But, as usual, this price will be after the hype subsides. While in all Chinese online stores they are sold at an inflated price. Below is a list of Aliexpress sellers with the most orders. The price depends on the version (Chinese or global, with and without NFC).

Sergei Vasiliev

I am interested in everything related to smart watches, fitness bracelets and other wearable electronics. With pleasure I will share the latest events in the world of gadgets, I will try to help you choose the best model and deal with the basic settings.

Battery Life

There is no difference in the level of autonomy between gadgets, since both devices can easily withstand up to 20 days without recharging. Although it may seem that the fourth modification should work longer due to the presence of a 135 mAh battery versus 110 mAh for the second hero of our review.

Here it should be taken into account that the novelty consumes more energy due to the need to ensure the operation of an already color screen.

Comparison table of characteristics

Parameters Mi Band 3 Mi Band 4
Display 0.78″ OLED 0.95″ OLED
Waterproof IP68 IP68
Compatibility Android from 4.4, iOS from 9.0 Android from 4.4, iOS from 9.0
Wireless technologies Bluetooth 4.0 bluetooth 5.0
Battery, mAh 110 135
Autonomy, days twenty twenty

Both options are delivered in a cardboard box, decorated in the traditional style for the company. The package includes the device itself, an instruction manual, a silicone bracelet and a cable with a capsule for replenishing the battery charge.

Comparison of Mi Band 3 and Mi Band 4 in appearance will clearly be in favor of the new version.

This is due to the fact that the screen size has significantly increased, which has grown by as much as 40%. The capsule formula itself remained almost unchanged, retaining rounded corners.

Water resistance has also been ensured, the indicator of which already in the third version was 50 meters under water, which means compliance with the IP68 standard. A similar indicator is typical for Xiaomi Mi Band 4, so with both devices you can not only take a shower, but also swim under water.

The design of the strap has not undergone major changes, it remains as ergonomic and comfortable as before. The only thing is that the novelty does not provide for the possibility of removing the capsule from the charging bracelet. This is due to the fact that the engineers decided to place the contact base on the back of the gadget.

Feature set

The main functionality has remained the same, so both devices can determine the heart rate, accept / reject calls, determine the current mode of operation, notify about the lack of physical activity, count steps, etc.

A feature of the fourth version is the presence of a smart alarm clock option, as well as a more advanced and powerful processor. It is characterized by the presence of built-in AI technologies, which are represented by cardiac biometrics modules for detecting heart rhythm anomalies. The implementation of the Always on technology has made it possible to significantly increase the efficiency of the chipset while significantly reducing power consumption.

The accuracy of the measurements taken has also been significantly improved, although in practice users will not always be able to feel this due to the high accuracy of the previous model. So, Mi Band 3 has a four-axis accelerometer, and the new product has a six-axis one. The quality of the heart rate monitor has also improved markedly. It is worth noting the transition to Bluetooth 5.0 LE technology, due to which the communication range has become even longer.

Display Features

The main difference between Mi Band 3 and Mi Band 4 lies in the quality and functionality of the screen. The third modification was the owner of an OLED touch screen, the resolution of which was 128×80 pixels, and the diagonal was 0.78 inches. Please note that the picture is displayed in monochrome. It is worth noting the correct operation of the display module in bright sunlight, which ensures a good level of information readability. To protect the matrix from damage, it is covered with protective glass Gorilla Glass with an oleophobic coating.

The same decision to protect the matrix was made in the new Xiaomi fitness bracelet, but the tempered 2.5D glass surface was given a flatter shape. The screen dimensions have increased significantly, so its diagonal is already 0.95 inches, and the resolution has increased to 120×240 pixels. And most importantly, now the display has become color, and there are no complaints about the playback quality. The picture looks juicy and bright in any conditions. The control remains touch-type, but the button that used to be located at the bottom of the screen has disappeared in the new Xiaomi fitness tracker.

Did Xiaomi Mi Band 4 manage to surpass its predecessor?

Comparing the capabilities and technical characteristics of Xiaomi fitness bracelets, it becomes obvious that the company has decided to take the path of improving existing gadgets. Almost without making changes to the design, she decided to move away from monochrome displays and rely on the color version, which is a significant advantage of the novelty. We are pleased with the improvement in wireless data transmission technology, as well as the preservation of high-quality moisture protection. Battery life remains the same.

The main difference between “Mi Band 3” and a fake is the service life, appearance, the presence of a full set of functions, the ability to connect to a Mi account.

Packaging and equipment

The first thing you should pay attention to is the charging cable. Fake is shorter than the original, smooth to the touch, does not leave a pleasant tactile sensation. There may be scratches, abrasions, traces of low-quality reflux on the surface. Sometimes there are options for grayish color, orginal. only black.

You can distinguish the original by picking up the strap. A counterfeit copy comes with a bracelet that has an unpleasant chemical smell. Most often, such an accessory is made of rubber. The original is a hypoallergenic silicone, harmless to health.

Branded Mi band 3 works without glitches and brakes, does not lose connection with the smartphone. The non-original almost always slows down, which is visually noticeable.

You can also identify a fake by the box. Xiaomi bracelets come in two types of boxes:

Both versions are sealed in a dense film, do not contain any extraneous stickers, except for a sticker with technical characteristics.


Manufacturers of counterfeit products do not always care about the quality of their products and their similarity with the prototype. Often they forget to put the original logo of the manufacturer.


The quality of execution is another sign that allows you to identify fraud. A fake fitness bracelet has poor-quality glass that protects the screen, the strap can cause allergies.

How to authenticate

It is not difficult to determine the original bracelet. It is enough to try to connect it to the proprietary MiFit application. If the device is synchronized, then it is original.

Fake manufacturers, in order to ensure the performance of their devices, offer their own software, stylized as the original MiFit. As a rule, it is suggested to install it in the instructions.

In order not to become the owner of a fake, it is sometimes better to overpay a little and make a purchase in a company store, or from a supplier that does not arouse suspicion.

Hardware differences between global, EU and Chinese versions of Xiaomi smartphones

Not only the software differs Global from EU and the Chinese versions of Xiaomi, there are more serious differences. support for certain frequencies of cellular modules.

If during the reign of GSM (2G) there were only 3 main carrier frequencies 850, 900 and 1800 MHz, and all phones in the world could work in any country, if there was a GSM connection, then the further the development of cellular networks went, the more difficult they became.

The 3G network has at its disposal several data transfer protocols: UMTS / WCDMA, CDMA2000 / IMT-MC, TD-CDMA / TD-SCDMA, DECT and UWC-136. At the same time, each of the protocols supports its own set of frequencies on which it operates.

The 4G network, or the fourth generation, reduced the degree of geekiness by introducing only 2 main protocols: LTE and WiMAX. However, due to the high bandwidth requirements of these networks, the number of frequencies on which the LTE protocol operates has increased significantly.

The frequencies on which LTE (and the new version of the LTE Advanced protocol) operate are divided into groups called “Bands” (Band).

Each Band has a group of previously known frequencies, for example: BAND 3 in the 1800 MHz FDD band, BAND 31 in the 450 MHz FDD band, etc.

In Russia, 5 LTE bands are used:

  • 3 in the 1800 MHz FDD band;
  • 7 in the 2600 MHz FDD band;
  • 20 in the 800 MHz FDD band;
  • 31 in the 450 MHz FDD band;
  • 38 in the 2600 MHz TDD band.

I’ve been talking about this for so long to make it clear the main difference between the hardware stuffing of different Xiaomi phone models designed for the Chinese and Russian markets.

China and Russia use different 4G bands, for this reason, if you buy a Chinese Xiaomi, there is no guarantee that it will work in fourth-generation networks in our country, and vice versa.

Therefore, buying Xiaomi on AliExpress at a suspiciously low price means a risk, the phone will come to you new, serviceable, but it was made and configured for use in China.

Bands cannot be fixed by flashing. different modem chips are installed inside.

What is the difference between Global, Chinese and EU versions of Xiaomi (Redmi) and which phones to use in Russia

Xiaomi is a Chinese company that, at the dawn of its formation, worked only for the domestic market.

China is a special country, not only geographically, but also socio-economically. For this reason, Chinese electronics manufacturers make two versions of the same product: for domestic use and for sale in Europe, the United States and other countries.

Xiaomi releases 2 firmware versions and 3 device versions:

  • Chinese. built-in services and applications that do not work outside of China, there are interface features (due to the use of hieroglyphs), there is no built-in support for Google services (the company is prohibited), only Chinese and English are supported.
  • Global. firmware intended for distribution around the world, except for China. Many languages ​​are supported, including Russian, Google services are built in, the interface has been changed in the direction more familiar to us, Europeans.

Be careful: Xiaomi some time ago spread the news that smartphones intended for sale inside China, but taken abroad and flashed with Global firmware, may be disabled. This is argued by economic considerations, phones for China are cheaper than global counterparts.

Cost differences

From a technical point of view, the EU version of Xiaomi can be used without restrictions on the territory of Russia, the Global version of the firmware will be installed on it, and the smartphone will support all bands of the cellular network.

The difference between the EU device and RosTest is that it will not be covered by the manufacturer’s warranty. And, of course, the Xiaomi warranty will not work for the Chinese version if you bought it from Russia.

Only phones with a RosTest certificate have an official Xiaomi warranty.

But our sellers got out of this situation, because it is profitable to import EU Xiaomi to Russia, their price is 10-15% lower, the quality is the same and the firmware with support for the Russian language is already installed. Therefore, the guarantee is given by the store, not the factory. If something happens to the phone, contact the store and he will take care of the repair, if the breakdown was not caused by your actions.
