Fast charging of a device is the salvation of many, which is why the technology has become popular. High-speed gadgets drain the battery once or twice. Most smartphone companies have their own variation of the feature. Samsung understands the customer’s wishes, and therefore most models support the technology. You can find out how to enable and disable fast charging on Samsung Galaxy in this article.
What is fast charging and why is it needed?
This is a smartphone feature that can charge the battery faster. Most companies use Qualcomm Quick Charge, since it comes with a processor, Apple, Google use USB PD, and there are companies with their own standards, Samsung is one of them.
At first the phone charges lightning fast, but after 60% the charging speed slows down. This is done to avoid overheating the device. Therefore, it is worth using original charging blocks that provide an increased level of current, calculated for a specific phone model.
High-speed charging on Samsung smartphones
The Korean company Samsung is a leader in the global mobile device market. In this regard, keeping up with others, it implements fast charging in its smartphones. In the phone body, it is controlled by Qualcomm's Snapdragon processor, which is now built into many mobile devices from other brands.
Quick Charge function
(fast charging) can be implemented by other means. The presence of the function can be found in the documentation about the device, which was included in the kit at the time of purchase.
Most cell phone chargers without this feature are rated at 10 watts.
Chargers with Quick Charge already have 20 watts or higher, and most often a USB Type C interface. But in fact, they use no more than 16-18 watts at maximum loads.
By increasing the power, such a charging unit can reduce the charging time of Samsung smartphones by almost half. Also, efficiency is dictated by the version of technology. The newer it is, the faster the device charges.
A charger with Quick Charge technology in mobile phones is also called Fast Charge. With its help, charging is not only fast, but also gentle. In the latest fifth version of Fast Charge, the function is implemented as efficiently as possible. The battery with 4500 milliamp/hour fast charging is able to top up from 0% to 50% in just five minutes. The subsequent process will take a little longer. And the full charge cycle will be completed in about 15-20 minutes. Provided that the battery in the device is new. And there are no power outages.
Models that support the function
Samsung is the market leader in mobile gadgets in the world. Fast charging on the Samsung Galaxy is based on Quick Charge 2. This option is installed on smartphones running Marshmallow (and other Android models), such as S9, S8, S7/Edge, S6 Edge+, S6 and Note 5.
For smartphones that do not have this function, download a special program from the Play Market. It will speed up the battery charging process; you just need to press the “Start” button. The program will automatically shut down processes that require high power. In the settings, you can make the application work autonomously when the unit is turned on. The smartphone itself enters economy mode: the percentage of screen brightness goes to zero, the network, Bluetooth, and Internet are turned off.
Why does your smartphone battery drain quickly?
There are several reasons for this phenomenon:
- battery wear;
- inappropriate memory;
- virus.
The battery wears out after 3-4 years of active use. This is if we talk about the branded battery that comes with the new Huawei or Honor phone. The charger that is less powerful in terms of throughput than the “native” one may be unsuitable. For example, if the kit came with a 2 Amp charger, and you use a 1 Amp charger, Honor or Huawei will take a long time to charge and quickly discharge. And the third reason is that there are a number of viruses that are aimed specifically at destroying the battery. To eliminate them, install an antivirus.
Enabling the mode
Enabling fast charging on a Samsung smartphone will not take much time. The process is the same on all models, but if the device does not have this option, the menu will look different. Conveniently, Samsung hasn't made this feature automatic, leaving users with the choice of plugging it in or continuing to charge from the cable. Instructions:
- Click on the gear and find “Optimization” in the menu that opens.
- Select "Battery".
- At the bottom, find the line “Fast charging”, move the slider to the right to activate it.
Charge Samsung Galaxy devices using Wireless PowerShare
Samsung Galaxy devices support Wireless PowerShare, allowing you to charge another gadget using your smartphone. Interestingly, charging other devices is possible while simultaneously charging your phone.
- Open the notification panel on your Samsung smartphone and activate the Wireless Power Share option. To do this, click on the icon (battery icon with an outward arrow).
- Place the device you want to charge in the center of the Galaxy dispenser. The back panels of the devices should be attached. The presence of cases or other accessories on the smartphone may interfere with the charging process, so it is advisable to remove them before starting the operation. An audible notification or vibration will confirm that charging has begun. If the battery charge drops below a certain level on the distributing gadget, the transfer function will pause.
If you still have questions about activating fast charging and the Wireless PowerShare function on Samsung smartphones, write to us in the comments.
Disabling the feature
Disabling fast charging mode will be necessary if the phone overheats. And the gadget overheats, because a high level of power is used in a short period of time. Therefore, you should not hold it on your knees, in your hands, or use it at all during the process. But, if the device is in a room that is constantly ventilated, or has a fan in the charging stand, this will not be a problem. Disabling an option is no different from enabling it:
- By pressing the gear on the display, go to the menu and find “Optimization”.
- Then - “Battery”.
- Next to the “Fast wireless charging” line, click the slider on the right, moving it to another position, deactivating the function.
Optimizing energy supply for Honor smartphones recommendations
There are also a number of general tips recommended for use on mobile phones manufactured under the name Honor. In some situations they can give the desired effect:
Restarting the device
It is only recommended not to simply start the procedure for restarting the smartphone, but to initially disable it. Wait thirty seconds. And activate the gadget again. If you use your phone for a long time, too many running processes may accumulate in the background. And this method will allow you to quickly get rid of them.
Entering Safe Mode
Many users know how to remove applications from memory. But sometimes doubts arise in favor of choosing one or another option. What if after such procedures something stops working altogether?
To solve this problem, it will be useful to temporarily launch the so-called safe mode. It will function only those programs and processes that are required to support full functionality. That is, it will be possible to view them and remember them. And then, after returning the smartphone to its normal state, use the information obtained in this way.
Safe mode starts like this:
- Use the ON button and hold it down for a few seconds;
- A menu will appear on the screen where you can choose what to do next (reboot, shutdown, and so on);
- You need to hold your finger on the reboot icon for a long time;
- An additional window will appear asking you to restart in the mode we need. Take advantage of it.
Return to default settings
It is quite possible that the owner of the gadget, while customizing the phone for himself, changed something in the parameters in such a way that this led to a problem with rapid discharge. Therefore, it is possible to return them to their original state. This is done as follows:
- Go through Settings to the “System” item;
- Select from the available options “Backup and Restore”;
- First, click on create a backup copy of your data, then click on restore.
Clearing cache
Yes, a cache that is full and has not been cleared for a long time can also lead to deterioration in the performance of a mobile device. Including the rate of battery discharge.
Therefore, we clear the cache in this way:
- Perform a complete shutdown of the smartphone;
- Press and hold the ON and PLUS buttons at the same time to get to the Recovery special menu;
- Using PLUS and MINUS, go to Wipe Cache Partition;
- Start the procedure using the ON button.
Wait for completion and initiate a restart of the mobile phone.
Reset to factory settings
Essentially, what makes this option effective is that it combines the previous two recommendations at the same time. And it is advisable to carry out this procedure through the same recovery menu.
Important! Before performing this process, be sure to save the data that you do not want to lose - this procedure leads to the destruction of absolutely everything that the user has managed to store in memory. Then everything is simple:
- The smartphone turns off and using the method described above, go to the recovery menu;
- In the list, select wipe data/factory reset;
- At the end, click to reboot, reboot system now.
What to do if the function does not work
There are situations when it is not possible to quickly charge a Samsung Galaxy; the time increases to standard. This happens for several reasons.
One of them is changing the original block. The “non-native” block slows down the speed. To solve the problem, go to the market and buy an original one. If the Fast Charge option works, the problem is resolved.
Also pay attention to whether the feature is enabled in the settings. On some gadgets it turns off automatically when they start to overheat. Do not use your smartphone while it is charging and turn off the lock screen, otherwise the device will charge slowly even if the icon is reflected on the display.
If the problems described above do not affect you, but charging is still slow, then the problem is most likely due to system failures. They arose when downloading applications not from official sources or due to the use of various custom Android firmware. To avoid subsequent problems, the user should reset the settings to factory settings.
It's easy to enable or disable fast charging on your Samsung Galaxy. The function is popular now, since devices are overloaded with documents and applications, and powerful batteries do not always save the day. It is supported by a large number of smartphones, and troubleshooting will not take much time. If there is no option at all, download the application. The number of advantages of the technology clearly outweighs the number of disadvantages.

Introduction, or how a smartphone battery works
Modern smartphones use batteries based on lithium chemicals. There are lithium-ion (Li-Ion) and lithium-polymer (Li-Pol) batteries, the difference between them lies in the physical properties of the electrolyte that fills the cell (“jar”). However, the general principle is the same: there are thin electrodes inside, and the space between them is filled with electrolyte.
When current is applied to the electrodes (which can be positive and negative, + and -), physical and chemical reactions occur inside the battery, leading to the accumulation of electrical charge. When a consuming device is connected to the battery, reverse chemical processes occur and the accumulated charge is transferred to the consumer. The flow rate of these processors is limited: the battery cannot charge indefinitely quickly (there is a current limit, after which the speed no longer increases, and the cell begins to degrade), and cannot discharge very quickly (the output current is limited by the speed of reactions).
Versatility
Not all smartphones are equipped with a Qualcomm processor. Luckily, there are other fast charging technologies available in various Android devices. Almost all of them work according to the principles described above. In this case, the phone can be connected to a high-performance charger from another manufacturer - nothing will happen to it. In some cases, its power controller will allow you to charge your smartphone at an accelerated pace. In other cases, recharging will proceed in the traditional mode - with a current of 1 or 2 A. In any case, the charger will not harm the device.
However, it is better to use the charger that came in the kit. There have been cases all over the world when the battery caught fire for some reason. This was caused by a Chinese charger and a low-quality USB cable.
Special mention should be made of products under the OPPO brand. It uses a unique VOOC Flash Charging technology. The batteries of smartphones equipped with it have eight contacts. Electricity enters the battery with a current of 4.5 A and a voltage of 5 V. The battery consists of several cells and the current is evenly distributed between them. As a result, recharging occurs very quickly. The manufacturer also claims that its technology is more gentle on the battery without reducing its service life.
Traditional charging
Any battery operates on the principle of an electromechanical process. It runs in both directions - the battery can receive energy, storing it, or release it. Over the years, engineers have tried different chemical current sources. Previously, nickel and lead were used, but now all cell phone batteries are based on lithium. They can be lithium-ion or lithium-polymer - it doesn't matter at all, since fast charging technology works with both types of batteries. The main advantage of lithium is that it does not have a “memory effect”. As a result, you don’t have to wait for the moment when your smartphone is completely discharged. Yes, and you don’t have to charge it to 100%. If not for this fact, fast charging would be useless. As for the disadvantages of lithium batteries, they include a gradual loss of capacity and a fire hazard.
Modern smartphones contain batteries with a capacity of 2000 to 7000 mAh. The nominal battery voltage is most often 3.5-3.7 V. When the battery is fully charged, the voltage can be increased to 4.2 V, which allows increasing the performance of the processor and some other components. As for charging the battery itself, it used to be very simple - current was supplied with a strictly defined power until the charge level reached approximately 90%. Then the power was gradually reduced so as not to “overcharge” the battery; this was done by a special controller. And so on until reaching 100 percent charge. As a result, the charging time was 2-2.5 hours, depending on the battery capacity.
