  • iPhone SE (2nd generation)
  • iPhone 11
  • iPhone 11 Pro
  • iPhone 11 Pro Max
  • iPhone XS
  • iPhone XS Max
  • iPhone XR
  • iPhone X
  • iPhone 8
  • iPhone 8 Plus

All listed models support wireless charging with Qi chargers. This is the most common format supported by most charging stations. However, when purchasing a wireless charger (especially on AliExpress), you should check the Qi standard. Otherwise, charging will not work.

Which iPhones have wireless charging and should you use it

Wireless charging is one of the main advantages of modern iPhones over previous generations of smartphones. It makes it much more convenient to recharge the iPhone in certain scenarios, without bothering the user with the need to connect a cable. Which iPhones support wireless charging and should you use it at all? This article answered the most common questions related to wireless charging.

Is it safe to use wireless charging

All leading manufacturers of smartphones and charging accessories have long agreed that wireless charging does not harm mobile devices in any way. However, each of the manufacturers emphasizes that this statement is true when it comes to proper wireless charging.

This means charging the smartphone with a high-quality charger, which will not lead to overheating of the gadget.

Overheating is the most important thing to watch out for when charging wirelessly. If iPhone gets hotter than normal charging, then you need to change the charging adapter or change the charging conditions. For example, do not charge your smartphone on a charging mat on the dashboard of a car in direct sunlight. In this case, strong overheating is ensured.

The main disadvantage of wireless charging

The biggest disadvantage of wireless charging is its low speed. For example, iPhone X charges in the usual wired manner using the included 5W adapter up to 14% in 15 minutes. Using a similar 5-watt wireless charging adapter, a little less charge runs up in 15 minutes. 10%.

It would seem that the difference is not the most significant. But it has a significant effect on the distance of full charge. On average, it turns out that wireless charging is one and a half times slower than wired.

This means that wireless charging will definitely not work if you like to charge your iPhone as quickly as possible. On the other hand, it will be a godsend if you can always keep your iPhone on the charging mat, for example, in front of your computer. In this case, the iPhone will practically always be on charge, which will allow you to really forget about using wires for charging.

How to use wireless charging

Wireless charging is as easy to use as a cable charger. However, for clarity, we provide detailed instructions:

  • Connect the wireless charger to a power source. This can be a computer USB port or a regular power outlet. After performing this action, the device should give some kind of signal, most often light or sound.
  • Place your phone on the wireless charging platform. Most often, there are no special requirements for this, but it is better to put the phone in the center of the block. If charging does not start, then check if a similar option is activated in the settings.

iPhone 12 MagSafe Charger Unboxing and Test

As you can see, the principle of action is very simple, so any user can handle it.

Thus, wireless charging is a special platform on which the phone is placed to start charging the battery. The principle of its operation is reduced to the interaction of magnetic fields between two induction coils located in the phone and the device itself.

How does wireless phone charging work?

The principle of wireless charging is pretty simple, of course, if you do not go into the physical details. The user connects a special platform to a power source in advance, and then puts a smartphone on it. It seems that everything is so simple, but in reality everything happens a little differently. An induction coil is built into the platform, which acts as a receiver and transmitter.

The exact same coil is located in the user’s phone. After connecting the platform to the current source, a magnetic field is formed around the coil. When you place the phone on the panel itself, interaction begins between the two coils. Electromagnetic waves are converted into electricity, which charges the phone’s battery.

The process is shown more clearly in the image above. Magnetic waves that are converted into electricity are shown in yellow.

What is Reverse Wireless Charging

Reverse wireless charging is an even more advanced version of this technology. It first appeared in 2018 on a number of Huawei and Samsung smartphones. Its essence boils down to the fact that with the help of one phone you can charge another, and completely wirelessly.

It is enough to lean two devices against each other and activate the necessary function in the settings. This is very convenient, as it eliminates the need for people to carry portable chargers with them.

What is wireless charging

As the name suggests, wireless charging allows you to charge various devices without using wires. It can be not only a phone, but also a camera, camera, tablet, smart watch, headphones and other equipment. Naturally, for this to work, the device being charged must support wireless charging. If there is no such support, then in some cases it can be implemented using a special cover.

This method of charging significantly saves time and eliminates the need for cables and connectors. The user just needs to put his phone on a special platform, and the battery automatically starts filling up. And to interrupt the charging process, you just need to take the device in hand, carrying it from the energy source by 5-10 cm.

Qi wireless charging standard

Many people think that wireless charging is new, but this is a misconception. Back in 2008, the Wireless Power Consortium introduced wireless charging technology based on the WPC standard. This name has not stuck in the memory of people, therefore, in various literature and descriptions, you can most often find the designation Qi.

The WPC standard states that wireless charging works thanks to two coils that interact with each other. One of them is located on the platform, and the other is on the user’s phone. Therefore, it turns out that the magnetic field covers two coils, thereby charging the battery of the device.

Today, many airports and bus stations offer their visitors to charge a smartphone or tablet completely wirelessly. This is where the Qi standard is used. However, not every phone can be charged over the air, so if you want to purchase such a technological platform, be sure to read the specifications of your device.

Which phones support wireless charging

Now wireless charging technology is actively gaining popularity and more and more new phones support it. At the moment, almost all flagship models can be charged wirelessly. Below we provide an up-to-date list of models with wireless charging.

Wireless & Accelerated Qi, Medium Power

Magnetically inductively charges iPhone using an Apple-Certified Qi iPhone Charger. Has a USB power adapter up to 10W. Usually the box of the purchased device indicates how much power it can squeeze out of itself.

Branded charger for iPhone

A classic white device that is familiar to all new iPhone owners, because it comes with every one of them. The charging block has a power of 5W and cannot quickly charge your device, as the new iPhone 11 Pro charger does with its 18W. It is clear. After all, it’s all about the numbers and the amount of energy that the device can take and receive. But, by the way, even it provides enough power to recharge your iPhone, since many Android smartphones still receive 2.2A charging in the kit.

Standard Qi Charging (Wireless) Low Power

Magnetically inductively charges iPhone up to 5W. And it is a pretty good charger, if only because it does not require connecting a cable that constantly breaks. No, it is not faster than conventional standard charging, you can see this in terms of power, but still it is much more convenient.

Fastest iPhone charger

Charging on iPhone only comes with an 18W or higher adapter and a certified USB-C to Lightning cable. You can purchase it separately or get it along with the brand new iPhone 11 Pro if you decide to upgrade.

Which charger is best for iPhone

Everyone is interested in this question, because buying a charger for your iPhone. this is a perennial problem that is very difficult to solve because cables can break and wireless chargers are quite expensive. Therefore, we decided to explain (using the example of the charge speed test data from MacRumors) which charging is better and whether it is worth spending money on a more powerful device.

Types of tested chargers: Original iPhone Charging 5W. 5W Choetech Standard Wireless Charger. 7.5W Apple Belkin Boost Up Wireless Charging Pad (tested at 5W and 7.5W). Apple’s standard 12W charger that comes with the iPad. 18W USB-C power adapter from Choetech. Apple 29W USB-C Power Adapter. Anker 30W USB-C Power Adapter. Apple 87 W USB-C Power Adapter

As we can see, the fastest way to charge an iPhone 8, 8 Plus, or X is with the USB-C power adapter and the included USB-C to Lightning cable. Charging with USB-C activates the “fast charge” feature, which is designed to charge the iPhone to about 50% in 30 minutes, and they’ve seen this charge level in all of their USB-C tests.

The most inefficient way (which is not strange) is wireless charging at 5V and wired charging similar in power to a standard iPhone adapter. They turned out to be the slowest charger tested. Interestingly, 12W charging was no worse than 18W or more powerful charges, because it charged the iPhone up to 72% in an hour, while the same charging with 30W of power was able to squeeze 77% out of itself in an hour for our device. Although these differences are very noticeable in the price of power.

Which iPhone models support fast charging

We find out. Which iPhone models support Fast Charging, which chargers are best for you, which ones to add to your shopping list, and more.

All of Apple’s iPhones have changed in terms of charging speed over the past few years, and to be honest, that’s just amazing. After all, now you do not need to sit for two hours and wait until the precious device receives its 100%, because the new iPhone 11 line can easily charge up to 50% in just 30 minutes if used with an 18W or higher adapter along with a certified charging cable.

For older versions (and for iPhone 11 as well), users need to purchase an additional USB iPhone power adapter and cable to perform high-speed charging technology on the iPhone.

IPhone 8, iPhone 8 Plus, and iPhone X devices support fast charging, if you purchase the appropriate accessories in addition.

But not everyone is so lucky, which is why the iPhone 6 only supports 1.6A and comes with a 1A charge. And the 2.2A charger that comes with the iPad won’t charge your phone twice as fast because it doesn’t technically come with fast charging support.

In general, the iPhone 11 Pro smartphone. it is the first Apple phone to come with fast charging. Of course, we’re all offended that the iPhone 11 won’t get this amazing miracle charging, but the biggest disappointment is that iPhones never made the jump to USB-C and are still equipped with a Lightning port. Although this is a small plus, because Apple put a USB-C to Lightning cable to the “firmware”, which means that you can finally quickly charge your phone from a computer by connecting your iPhone to one of the Macs.

Today we will try to understand what types of iPhone chargers are and how quickly and efficiently they perform their function:

Xiaomi Mi 10 8 / 128GB

Xiaomi’s latest flagship has both fast and wireless charging. There is still no water protection, it will appear on the Mi 10 Pro version.

From now on, it is not the same cheap flagship, which were, for example, Mi 8 and Mi 9. Mi 10 costs as a similar flagship of most other companies. Why? There are many reasons, here are a few of them: one of the best AMOLED matrix with a screen refresh rate of 90 Hz and a high brightness level, a top-end Qualcomm Snapdragon 865 processor, fast LPDDR 5 memory, a very powerful 4780 mAh battery with an unusual shape, which made it possible to reduce the size of the case. a gorgeous camera with a main module that is capable of shooting at a resolution of 108 MP.

The appearance is laconic and very much resembles another model of the company. Mi Note 10.

Which gadgets support wireless charging

and more smartphones belonging to the top class are compatible with wireless chargers. The Xiaomi Mi Mix 2S smartphone was one of the first to receive the Qi module on board, followed by the release of Mi9 and Mi Mix3, which have the ability to quickly charge wirelessly.

Huawei is not inferior to competitors and is releasing the Mate 20 Pro, which has received the ability to share the charge with similar gadgets. The well-known “daughter” of Honor cannot yet boast of the presence of models with Qi, it is possible that the situation will change in the near future.

iPhones from release 8 have been supporting wireless charging technology since 2017. However, it should be noted that charging over the air in the latest iPhones is slower than charging with a cord.

Samsung implemented the Qi standard that was introduced in the Galaxy S7 in 2016. After that, all models of the above series were able to charge wirelessly from charging stations.

How wireless charging works?

Qi is an accepted standard. It defines the principle of operation of a wireless charge, which is based on a physical phenomenon. electromagnetic induction. The standard is set by the Wireless Power Consortium, WPC, and regulates the use of technology that makes it possible to send energy wirelessly. The distance over which energy can be sent is up to 4 centimeters.

An inductor generates an electromagnetic field when the charging station is plugged into a power outlet. In order for a gadget to be able to receive energy through the air, it must have a built-in Qi receiver that receives electromagnetic waves. The phone starts charging as soon as it is placed on the platform. Charging efficiency depends on the materials of the phone case. Models capable of charging from wireless chargers are mounted with ceramic or glass backs.

Which Xiaomi smartphones support wireless charging?

Wireless charging is still an expensive feature, and therefore, if it is used on touch devices, it is usually on the most expensive ones. The thing is extremely convenient: no need to get tangled in the wires, charging is automatic, you just need to purchase a wireless charging module separately. The modules themselves are relatively inexpensive, so there shouldn’t be any problems with purchasing them.

As for Xiaomi smartphones, at the time of this writing, only a few Xiaomi smartphones support wireless charging functionality. About them. below.

DOOGEE S60 Lite

Again, an inexpensive, shockproof model with claimed wireless charging capability. A solid 5500 mAh battery, indestructibility and water resistance are the main advantages of the device.

The hardware of the smartphone is at the bottom of a decent job in 2019: an outdated MediaTek processor, 4 GB of RAM, weak cameras. The device itself is recommended for people who need a combination of shockproof phone and wireless charging at a low cost.

How wireless charging works

Samsung was the first to introduce this technology into its products on Android devices. Initially, only flagship owners had such an opportunity. But gradually, other manufacturers picked up this trend and began to supply more and more of their devices with it.

The principle of operation of this technology is in a special qi module. It connects to the network must be within range of your smartphone. A receiver must be installed in the phone. When the devices fall into the range of each other, a magnetic field is created between them, which increases the battery charge on the smartphone.

QI standard

The Qi sample, adopted by the Wireless Power Consortium, is firmly established in the market and is massively used for the production of wireless chargers. The title reads correctly as “Qi”. In Chinese culture, this word means the energy of nature, the universe.

To comply with the standard, an instrument must have the following characteristics:

  • 5V voltage;
  • 1 or 2 A of amperage;
  • up to 5, 10 or 15 watts of power, as in the case of the Wireless Charging Pad.

The new models provide a protocol for exchanging data between the conductor and the receiver. With its help, the Explorer receives information about the connected device, including the charge level and battery capacity. Based on these indicators, the required current strength is determined, and the charging is automatically disconnected when the battery is 100% charged.

Principle of operation

Electromagnetic induction became the basis for creating devices, therefore, charging of this type is often called “inductive” or “magnetic”. Its principle of operation lies in the ability of electromagnetic radiation to transmit current over a short distance without wires. This requires two coils, one of which will be the conductor and the other will act as the receiver. If you place them close to each other and start up an alternating current on the first, an alternating current will also be formed on the second, the receiver. It can be used as source of energy for the phone after transformation into a constant voltage of the required value.

The operation of wireless charging for iPhone 8 and 8 Plus, as well as for analogs, depends on the distance between the conductor and the receiver. The magnetic field is wasted and the technology doesn’t work as expected when it’s further away.

For high-quality contact, not only the air space between the elements is suitable. The magnetic field is not interfered with by plastic, glass, wood. Only metal will not miss it. At the same time, various models of devices have certain parameters of the permissible distance and rate of charge.

How wireless charging works: 5 basic features

In the field of charging for electric devices, “revolutionary” events are rare. One of the latest achievements is the unification of connectors on Android smartphones and push-button devices thanks to USB.

Now it’s the turn of wireless chargers. even Apple has strained itself and released three series of iPhones with support for this function. But what are contactless devices in fact, what is their principle of operation and how much truth is there in the Internet myths about their harmfulness? All useful information is in the article.

What is wireless charging?

A wireless charger like the Wireless Charging model is a panel that transfers energy to the gadget that lies on it. The device itself is powered from the mains. There are also models that work like a power bank. an integrated battery allows you to use the device without being tied to a power source. This quality will help out in the car, outdoors, in an emergency. The only thing that is required from the owner is to charge the drive in a timely manner.

The official date of the appearance of the device is 2009. The starting point was the founding of the Wireless Electromagnetic Energy Consortium. Before that, companies experimented with modifications and offered chargers designed for specific phone models.

To put things in order in the field and unify devices, manufacturers of gadgets and related electronics decided to join forces and develop a basic standard for wireless stations. The Qi technology has become the benchmark: chargers operating on its basis and meeting its requirements are universal and interchangeable. Every Qi compatible smartphone will work, regardless of brand.

Harm from contactless charging

Each new technology or device that uses physical phenomena and processes invisible to the eye has for a long time caused superstitious fear and apprehension in a part of society. Even microwaves are still accused of secretly affecting human health, food and global warming. And this is with more than 50 years of history of existence and use.

The same is true for remote charging. Ignorance of the elementary laws of physics is fertile ground for the emergence of myths and speculations about the dangers of devices for the iPhone X and other models. Here are two of the most popular ones, with a rebuttal:

Myth: The electromagnetic waves of a working device irradiate a person and cause damage to health. Reality: Radiation belongs to the non-ionizing type, therefore it does not affect the human body in any way. In addition, the electromagnetic field generated by the devices does not exceed 50 mm. This means that it will finally disintegrate already half a meter from the source.

Myth: Proximity charger accelerates battery wear, decreases capacity. Reality: It is not the actual use of the technology that spoils the battery, but its misuse. Frequent recharging instead of full-fledged “refueling” by 80-90%, working with the gadget during the charging process accelerate the waste of the drive’s resource. Typically, capacity starts to drop after the 500th charge cycle. “Recharging” the battery several times a day brings this moment much closer.

Development prospects

Wireless chargers are now at the stage of active research and search for alternative Qi solutions. The main task, according to manufacturers and consumers, is to expand the coverage radius, increase efficiency and use other energy sources.

So, the Americans are testing the technology for transmitting an electromagnetic wave from a router through free wi-fi channels. At the same time, the distance between the translator and the receiver during a successful experiment was 8 meters.

Key features of wireless devices from Samsung and other brands are the benefit of the USB ports of smartphones, which will last longer, and the reduction in the number of wires for gadgets. In addition, the devices are optimal for use in public places. airports, restaurants, offices.

Model Compatibility Output current, mA Output voltage, V
Wireless Charging Pad Android, iPhone 8, iPhone 8, iPhone X one up to 15
Samsung Galaxy S8 Galaxy S8, Galaxy S8 one up to 9
Wireless charging Android, iPhone 8, iPhone 8, iPhone X one up to 7.5

A wireless charger for iPhone or other smartphones is a modern accessory that is convenient to use at home and office. The USB-input will last longer as new, and the accessory looks stylish and elegant, unlike the cords that are always dangling and hanging from the sockets.

In order not to spoil the battery, you will have to follow the rules and unlearn the habit of taking off the charge and using the phone 50-55% charged. As for manipulating the gadget while charging, it also hurts in the case of standard charging blocks. And yes, metal covers must either be abandoned altogether, or removed every time before installing on a contactless device.
