Samsung fast charging stopped working

How to enable fast charging on Samsung

If you have recently disabled the option, you can do this in the system settings. Using the example of disabling the option, consider how to reverse this process.

What is Fast Charging in a Samsung smartphone

A standard charger in modern smartphones has a capacity of 10 watts. In phones with support for Fast Charge charging, the declared power of the adapter is 20 watts (in practice, this figure rarely exceeds 18 watts) Accordingly, the more the power of the unit increases, the faster the battery is charged.

This technology was first patented by Qualcomm, which proposed the Quick Charge standard in 2013. Since this technology is proprietary, the Korean manufacturer Samsung has developed its own development, Adaptive Fast Charging, based on Quick Charge 2.0 technology.

Quick Charge compatible

Samsung Fast Charging is compatible with any Quick Charge-enabled device. With this adapter, you can charge any device with the Quick Charge 2.0 or Quick Charge 3.0 logo. In this case, keep in mind that the process will take place according to the standard of the 2nd version. A smooth power change will not work in this case, and the phone will charge a little slower than on the adapter of the third version.

How to disable fast charging

To disable the option, you need to repeat the following steps:

Swipe down the screen by lowering the top curtain with the system menu, and click on the settings icon. You can also go to the parameters using the phone menu.

  • In the parameters, select the section “Optimization”.

samsung, fast, charging, stopped

  • Here we need the “Battery” icon. it is located in the lower left corner of the screen.
  • In the window that opens, click on the menu button (three dots in the upper corner of the screen) and open the “Additional settings”.

Here we see the mode switch. We translate it into the mode we need.

All About Samsung Fast Charging. User Guide

Samsung fast charging is one of the innovations of the well-known Korean brand, which significantly speeds up the process of charging a mobile device. Users are happy to use it, because it is so pleasant. not to wait several hours until the battery is fully charged, but to get the result in less than an hour. However, few people know how this option works, how it can be configured and even disabled.

How Samsung Fast Charging Works

The Samsung Adaptive Fast Charging technology is based on a stepwise change in current capacities depending on the percentage of battery charge. The lower the percentage of charge, the more power is delivered by the adapter.

As the percentage of charging increases, the current setting in the adapter changes. The power gradually decreases to 10 watts at a 95% charge level. In this case, the decrease does not occur smoothly, but in stages. This significantly reduces the efficiency of recharging the battery, since the controller does not fully control the current changes. This bug was fixed in the updated Quick Charge 3.0 standards and all subsequent versions. the voltage during such charging changes in 0.2 volt steps, which is more efficient and safer for the phone battery.

Missing fast charging on Samsung. reasons and what to do?

To begin with, we note that a full battery charge within the terms stated by the manufacturer is guaranteed only if during the process you do not use the phone, and separate applications are not running on it in the background. Any running process will decrease the speed of the process to one degree or another, depending on the energy consumption of the application processes. Most of all, the charge is taken up by the turned on screen and running multimedia files. If you notice that the phone is charging too slowly. check if you have any additional services or applications enabled.

Also check if the option is active using the special section in the settings, which was mentioned above. You may have previously accidentally or intentionally disabled it.

If charging is pathologically slow or does not work at all, check the serviceability of the adapter itself using another device, and the connector on the phone using another cable. If you notice a malfunction, contact the service center to fix the breakdown.

If the Samsung phone does not charge from the charger, I will tell you why and we will fix it together

Good time, my regular blog readers and subscribers! Often, users of mobile technology are faced with the fact that their device does not charge. Sometimes the device does not display the charging process, and in other cases the indication is present, but the capacity in fact remains unreplenished or the battery gains 100%, but quickly sits down. Why Samsung Phone Won’t Charge, I’ll Explain in This Article.

Choice of accessories

If you look at the accessories for phones five years ago, it is easy to see that the power supply often has a charge (current) of 1 Ampere. Later, blocks with increased power began to appear, and in modern gadgets from the Galaxy A and S series. A70, S8 and above, you can see the most powerful chargers. The reason is the appearance of the fast charging function. It is achieved through increased current flow and it is wrong to assume that this works with any accessory. Sometimes the power supply and cable included in the kit are not designed for quick replenishment of capacity and the necessary accessories are sold separately.

If a proprietary charger cannot be used, then you should not just replace accessories from a third-party smartphone or buy the most inexpensive options. They are highly likely to do a poor job, for example, the phone will remain discharged, although it shows that charging is in progress. The reason is that the current that flows through the incomplete accessory is enough only for minimal actions, and the device cannot send something “to the reserve”. A similar situation is often observed if, while charging, you play or watch videos on YouTube, you do not have to be surprised that the charge remains in one place in this case.

Also, do not charge a modern mobile phone, especially if it is an expensive device like Samsung A80 from the USB connector. they are not designed to recharge the capacious batteries of modern phones. But, if you find a Type-C connector in your laptop or PC, then feel free to connect the appropriate cable. this is a new standard with increased current supply, which is able not only to read data, but also to power the phone.

Physical reasons

The first thing that comes to mind when the smartphone does not charge from the charger is a broken cable, block or the gadget’s connector itself. In this case, it is worth checking everything. An important point. you should not check the functionality of the cord by pulling it out of the power supply and plugging it into the laptop. Due to insufficient voltage, the new Samsung models. A50 and above may not receive power or do it too slowly, which will make the user think about damage to the cable. Ideally, you should take a power supply and cable from a similar Samsung gadget. If they are not available, third-party accessories with the same parameters on the adapter will do.

[Solved] Samsung Type C Fast Charger Not Working for Samsung Phones S8 S9

Checking the cord, power supply and connector does not give unambiguous answers about the presence of physical damage. Sometimes the reason lies in a burned-out power board or microcontroller. He realizes that the battery capacity is full and stops supplying current. This node is extremely important in the phone. if it is broken, then the device may think that the battery is discharged and does not turn on, but in fact it is full, or vice versa. the battery does not charge although the capacity is at zero. It is impossible to establish whether the matter is in the internal nodes in the home environment. Having tried the methods listed below and not finding a solution, you should contact the service.

It is important to know that degradation is characteristic of any battery. This term implies that during use, the battery gradually deteriorates. it charges slowly and autonomy decreases. If the phone is more than a year old, and it began to charge for a long time, but the power supply and cable remained complete, then 100% of the reason is in the battery. it should be changed.

Software problems

What to do if Android Samsung does not charge from charging or does it slowly, but you have established that the cable and the unit are working properly. The reasons for this behavior may be in a damaged battery, but sometimes it lies in the software. For proper charging, you need to unload applications from the memory, if there are a lot of them there, reduce the brightness of the screen. If the device is synchronized with something via Bluetooth, then it must be temporarily turned off, a similar situation with access to the network via Wi-Fi and LTE.

It will not be superfluous to look into the smartphone’s power settings. Look for the item “battery” and make sure that the maximum performance mode is not activated. By itself, it is more needed by gamers, but even without it, a good device provides a comfortable work. If you have energy saving, then activate it, but first go and check what it is, sometimes the processor hard cuts off the work of applications, and you will face the fact that you will no longer receive notifications. You will eliminate slow charging this way, but you will get other problems. Power saving mode is not always useful.

Do not forget that any running applications are a drain on battery power. If you closed all the software, but the phone still sits down quickly and does not fill the battery, then the reason may lie in viruses. Do not neglect antiviruses, but if you do not use them constantly, then make it a rule to completely check the device’s memory with some frequency. perhaps cleaning will solve the problem with slow charging or its absence.

Many users are wondering why the phone does not charge up to 100 percent. Technically, this shouldn’t happen at all. If you see that the device has reached 99% and then nothing happens, then everything is working as it should. In modern mobile technology, battery protection is implemented. when it is full, the phone stops being powered directly from charging, as this leads to rapid wear and tear and forcibly cuts off the current supply. This is possible with branded accessories, so this is another reason not to change them for cheap Chinese counterparts. over, in the modern world it has been established that for long-term battery operation, it should be kept between 20 and 80% of its capacity, that is, you should not discharge and charge it completely.

How the fast charging function works for Samsung?

What distinguishes a modern Samsung smartphone in the first place? That’s right, high-performance video chips. This is cool, as it opens up many possibilities, but at the same time the power consumption of the gadget grows.

Now you will say that along with the improvement of the models, the capacity of the batteries has also increased, the dimensions have grown, and therefore the charging time has increased. Alas, we must grieve you, this did not give a big breakthrough.

But do not be upset, the manufacturers have tried their best, and the new models have a fast charging function for Samsung! In addition, an additional innovation has become a unique wireless charging, which eliminates the need to be constantly “tied to an outlet”.

How does this function work and what are its features? Now you will find out about everything!

Energy losses are minimized!

A unique wireless device, Qi Charger, has been developed specifically for models such as the Galaxy S6 Edge Plus and Galaxy Note 5. In its lower part there are several ventilation holes that cool the system.

Plus. there is a fan in the middle. All this allows you to quickly and easily recharge smartphones in any conditions.

Regarding other models of gadgets, then the developers have gone further. As you know, the principle of operation of any storage batteries is an electrochemical process. It is he who gives and accumulates energy.

To prevent phones from draining quickly and retaining energy for a longer time, lithium-based batteries began to be produced. They are responsible for the “fast charge” mode.

When connected, energy is delivered from the maximum power charger in the first stages. This means your smartphone is charging as quickly as possible.

This function can be disabled or enabled. When charged from a cable for only 10 minutes, the gadget remains secured for four hours of battery life. Agree, earlier this could only be dreamed of!

Previously expensive wireless charging is now available to everyone. Since it is sold together with a set for some models of Samsung smartphones. Wireless charging technology also supports any other device.

To find out if your phone supports this innovation, do the following:

  • Go to the “Settings”.
  • Open the “Battery” section.
  • Check if an app is listed that is using the entire battery.
  • The app can be used or disabled.

We can definitely say that the “fast charging” function has made the phones of the famous company even more advanced, cool! Competitors are clearly biting their elbows.

And we can only say: “Bravo!” developers and expect new technological breakthroughs from Samsung!

What is fast charging

Fast charging is a technology that allows your smartphone’s battery to charge faster than usual due to the increased amount of current flowing through the adapter into the phone’s battery.

Xiaomi and Redmi smartphones use a fast charging technology called Quick Charge, developed by the American company Qualcomm. The principle of operation of Quick Charge is to supply current with a voltage that exceeds the standard indicator. 5 V. Thanks to this, the smartphone can be charged from 0 to 100 percent in about half an hour (depending on the generation of technology, the charging speed varies).

In the second generation of Quick Charge, the charging speed has increased significantly. more than half of the battery can be charged in half an hour. Photo: Ryo FUKAsawa /

First generation. It appeared in 2013. then only top devices with a Snapdragon processor supported fast charging. This generation of Quick Charge devices charged only 40% of the battery capacity faster than usual.

Second generation. The speed is increased to values ​​that provide 60% of the battery in half an hour. For charging, you had to use a device with a voltage of 9 V and a current strength of 2 A.

Third generation. Intelligent voltage control has appeared, thanks to which the device selects the desired value of this parameter for each stage of charging.

Fourth generation. These devices charge half of the battery in just 25 minutes. Quick Charge 4 technology is available for smartphones with a Snapdragon 835 processor and newer, that is, for the flagships of previous years and a number of mid-budget devices. This generation introduces support for USB-C and USB Power Delivery standards.

Fifth generation. So far only available on the flagship Mi 10 Ultra. This is a powerful 100 watt charger that can charge a 4500 mAh battery in 15 minutes.



Not every smartphone has a built-in fast charging technology. most often, manufacturers equip only flagships and mid-range models with it. But Xiaomi has this feature even in the most inexpensive devices. What is Quick (Fast) Charge, how fast charging works and which models support it. let’s figure it out together.

Which Xiaomi smartphones support fast charging

Most Xiaomi models today support some form of fast charging.

Mi Charge Turbo 30W wireless charging. Photo:

Xiaomi smartphones support wireless fast charging! Quick Charge wireless chargers work with commercially available Quick Charge 2.0, 3.0, 4 and 5 adapters. Xiaomi Fast Car Charger is also available.

How to turn fast charging on and off

Before connecting the cable to your smartphone, you need to check that three conditions are met that are necessary for fast charging to work:

The operating system of the smartphone must be native MIUI. The technology may not be supported on custom firmware.

It is better to install updates to the latest version. Smartphones with older firmware may not support the function.

After making sure that these conditions are met, you just need to connect your smartphone to the charger: Xiaomi Quick Charge is activated automatically, as it is built into the firmware and hardware of the smartphone. If something is not observed, the smartphone will charge normally.

Fast charging works automatically, you don’t need to turn on anything on purpose. Photo:

To check if fast charging works, you need to pay attention to the right corner of the top panel of the smartphone. If there is a lightning bolt icon in a circle, the function works. The second method (more dreary, but one hundred percent reliable): just measure the charging speed. If the battery is charged more than half in twenty minutes. Quick Charge works properly.

The lightning in the circle is the Xiaomi fast charging icon. Photo:

Some manufacturers’ phones, such as Samsung, can turn off fast charging. Xiaomi has not provided such an opportunity in its devices. Again, all due to the fact that the function is built-in and automatically turns on when the charger is connected and turns off when disconnected from the power.

What to do if fast charging does not work at all or stops working on Xiaomi

Check if the three conditions described above are met: original charger (Xiaomi fast charging unit / adapter), native firmware, latest updates installed.

Xiaomi fast charging can also “disappear” in case of overheating: if you actively use the gadget while charging or it gets hot in the sun. Do not do this.

In rare cases, the problem is on the software side. Then a full factory reset or flashing the device can help you.

If all this does not help, you should contact the service center.

Does USB Cable Affect Fast Charging? A defective or poor-quality USB cable can adversely affect the charging process. Therefore, if it has external damage or shorts it periodically, replace the cable as soon as possible.!

Does Quick Charge do any harm?

Not unless you use the Quick Charge charger with gadgets that do not support fast charging technology. Overvoltage can damage both the battery and the device.

Proper fast charging will not harm your device. Photo:

Xiaomi fast charging gadgets have a number of means to protect the device while power is on, including a temperature control mechanism, short circuit and overvoltage protection.

At the same time, in order to extend the life of the battery, only two conditions must be met:

Do not bring the gadget to full discharge: this causes chemical reactions that harm the battery in the long term.

Make sure that the gadget does not overheat: during charging, do not use resource-intensive applications, do not leave in the sun, do not cover, etc.

Why you need to disable Fast Charging on Samsung Galaxy?

But before we start, let’s take a closer look at the reasons, because I know many people don’t understand: why would anyone want to disable fast charging on Samsung? There are several reasons, but the main one is heat, or rather, overheating. Fast charging uses a lot of current in a short time, so the device can easily overheat.

If it sits on a nightstand in a cool, ventilated area, this may not be a problem. But if the phone is on your lap while you are driving and the sun is falling on you, the device can get quite hot

On the other hand, devices like the Galaxy S7 / Edge with wireless charging have a fan in the charging cradle that can turn on when in use. Some people hear this faint noise and find it annoying, and disabling Fast Wireless Charging prevents it from occurring.

How to Disable or Enable Fast Charging on Samsung Galaxy?

Now that you know why you should enable or disable fast charging on Samsung, let’s take a look at how you can do it. The good news is incredibly easy and you are just a few taps away from success.

I’m using the Galaxy S7 Edge for this tutorial, but the process is pretty much the same for all Galaxy devices. just keep in mind that if the device doesn’t have wireless charging, the menu might look slightly different.

The first thing to do is go to the Settings menu by pulling down the notification bar and touching the cog icon in the upper right corner.

Scroll down the menu until you see Optimization. Click on it.

Now go to the bottom of this menu. Depending on the device, there are one or two options here: “Fast Charging” and “Fast Wireless Charging”. Toggling the slider to the right of any option enables / disables it.

It’s especially good that Samsung has separated these options so that you can choose to continue to charge quickly via the cable, but disable this feature for wireless charging, or vice versa. As you wish.

Samsung is missing fast charging

How to disable Fast Charging on Samsung Galaxy (S7, S8, S9 and any other model)? Why you need to disable and enable fast charging?

Everyone loves when their devices charge quickly, right? This is why so-called fast charging technology is so popular. at the moment, almost every phone manufacturer has its own version. However, in some cases, fast charging may not be the best solution.

Thankfully Samsung understands the need to disable this option on the fly, and there is a way to do it on Galaxy devices running Marshmallow (and other Android versions) such as S9, S8, S7 / Edge, S6 Edge, S6 and Note 5.

Galaxy S8/S9/S10: FAST Cable Charging Not Working? FIXED (10 Solutions)

Why Sometimes Fast Charging Doesn’t Work on Samsung?

Even when this feature is enabled, the phone won’t always charge quickly, as noted by Samsung users. If you use your phone while charging or leave the screen on, it will charge much more slowly. It takes about three hours to fully charge a Galaxy S8 with the screen on. the same as a “regular” charge.

“Remember, just because you see the Quick Charge icon when you are using your device does not mean that you are really getting the maximum charge. This does not happen until the screen is turned off ”.

You will not find this helpful tip in the Galaxy manual.

And this isn’t the first time something gets in the way of fast charging. Google Pixel disables fast charging when the phone’s internal temperature goes over a certain threshold.

In my time with the Galaxy S8 Plus, I noticed a significant difference in how quickly it charges if I use the battery at the same time. But it never dawned on me that fast charging doesn’t really work when the screen is on or the phone is in use.

In this case, if you need to quickly charge your Galaxy S8 before you go on the road or out for a walk, it is better to turn it on and leave it alone for a while.

Good day. There is a Samsung Galaxy S6. Over time, fast charging began to stop working. it worked, then it stopped. I thought the problem was in the block. The block was changed to a similar one. the problem did not go away. When the problem reached its climax (fast charging stopped working altogether) I took it to the official Samsung service. The master said that it was necessary to replace the bottom board, indicated the price tag and said to come for the smartphone in an hour. When he came to pick up, the master said that the problem was not in him, and replacing the lower board would not help. I refused to work. Okay, I took it to the service, to the diagnostics. the result of the diagnostics was a recommendation in the form of replacing the main board and a price tag of 15600. Logic says that the problem is more likely in some element (I still sin on the power controller, but my knowledge here is small ) Sobsna, the question is. are there specialists who will accurately identify the problem and the price tag of the repair? I would like to understand whether it makes sense to repair it or is it easier to think about updating your smartphone. Don’t drown in cons only) Comment for cons inside.

Samsung Galaxy S6 phone. Always charged with a cable. This morning I noticed that the time to full charge began to show 4-5 hours. The “quick charge” function no longer works. What could be the matter? I unplug the cable, the function appears, I plug it back in, disappears. What the hell ?! Previously, the phone charged from 0 to 100 percent in about an hour and a half.

I bought the phone in June 15. I read on the Internet that the “fast charge” function should be used only in extreme cases, if you are in a hurry somewhere. And I thought it was a “feature” of the Samsung and used it for almost a year. And it turns out, if you use it constantly, it quickly destroys the battery. So what’s now? Rub me from 0 to 100 percent, I need to wait about 8 hours.
