The fast charging feature in Xiaomi Poco F3 smartphones allows you to restore battery power in minutes, but it does not always benefit the device. Many users face overheating, accelerated battery wear or simply prefer a more gentle charging mode. In this article, we will discuss all the available ways to turn off fast charging on the Poco F3 – from standard settings to hidden engineering menus.
Disabling accelerated charging can be useful in several cases: if you notice that the phone is heating up a lot while connecting to the network, if you plan to leave the device on charge overnight, or if you want to maximize the life of the lithium polymer battery. It is important to understand that the manufacturer does not always provide a direct option to deactivate this feature, so some methods will require additional manipulation.
Before you start settings, make sure your Poco F3 runs on the current version of MIUI firmware. In older builds, some settings may be missing or located in other menu sections. Also remember that turning off fast charging does not mean stopping the process completely - the phone will simply charge at a standard speed (usually up to 10 W instead of 33 W).
1. Disable fast charging via standard MIUI settings
The easiest and safest way to do this is to use the built-in options, and depending on the version of MIUI, the path to settings may vary slightly, but the general logic is maintained.
Open the Settings app on your Poco F3 and go to Battery and Performance. Here you are interested in the Charging submenu or Charging settings (in some firmware, this may be called Charging Optimization).
Inside this section, find a switch called Quick Charge, Turbo Charge or Quick Charge. If you don't have one, try searching through the Settings search bar (the magnifier icon in the upper right corner).
- 🔍 Search by settings: Enter the “charging” or “fast charge” request to quickly find the desired section.
- ⚡ Switch: If the option is active, simply move the slider to the "Off" position.".
- 📱 Confirmation: The system may request a device restart to apply the changes.
If your version of MIUI does not have a direct disable option, it does not mean that the feature is not available, it may be implemented through an engineering menu or requires the activation of hidden parameters, which we will discuss in the next sections.
☑️ Preparation for fast charging shutdown
2.Use of the engineering menu (for experienced users)
If standard settings do not allow you to turn off fast charging, you can use the Engineering Mode, which requires caution, since improper actions can lead to malfunctions of the device.
To open the engineering menu, enter the following code in the Phone application:
##4636##After that, a menu with several tabs will open, and you need the Battery Information tab, and you'll see detailed battery status data, including temperature, charge level and supported charging protocols.
To turn off fast charging, follow the following steps:
- Go to the Battery Settings section (if any).
- Find the Fast Charge or Quick Charge option and deactivate it.
- Save the changes and restart the device.
⚠️ Note: Not all versions of the Poco engineering menu F3 If you don't find one, don't change the other settings, which can cause the phone to run unstable.
An alternative way to access the engineering menu is through the MTK Engineering Mode app (for MediaTek-based devices). However, the Poco F3 is equipped with a Qualcomm Snapdragon 870 chipset, so this method won't work. Instead, you can try apps like QuickShortcutMaker to find hidden charging settings.

3. Disconnection through ADB-Teams (for advanced users)
If previous methods have not worked, you can try to turn off fast charging using the help of ADB-Android Debug Bridge, which requires you to connect your phone to your computer and install special drivers:
First, activate the developer mode on Poco F3:
- Go to Settings. → The phone.
- Click on MIUI Version 7 times in a row until the notification “You became a developer” appears.
- Return to the main settings menu and open the section Additional → For developers.
- Activate the debugging option via USB.
Now connect the phone to the computer through USB-cable (preferably original) and follow the following steps:
- Download and install ADB Tools on PC.
- Open the command prompt (Windows) or terminal (macOS/Linux) in the folder with ADB.
- Enter the command to check the connection: adb devices If the device is determined, you will see its serial number.
- Execute the command to disable fast charging: adb shell settings put global fast_charge 0
- Reboot the phone.
To return fast charging, use the same command, replacing 0 by 1. This method does not work on all firmware, but often helps when standard methods are not available.
⚠️ Attention: Misuse of the right ADB-You can crash your system, don't change other parameters unless you're sure they're there. USB Only enabled when connected to trusted devices.
4. Charging management applications: should you trust?
There are many apps on Google Play that promise to control the charging process, including disabling fast protocols, but most of them can’t be trusted for several reasons:
- 🚫 No real impact: Many applications simply display battery information but cannot change system settings.
- 🔒 Security risk: Some programs require a superuser right (root), which can compromise the security of the device.
- 📉 Incorrect job: at Poco F3 With closed firmware, such utilities often fail or do not work at all.
If you do want to try, consider the following apps (but be aware of the risks):
- 🔋 AccuBattery – monitors battery status and offers optimal charging modes, but does not turn off fast charging directly.
- 🛠️ Battery Charge Limit – allows you to set a charge limit (for example, up to 80%), but requires root rights.
- ⚡ Quick Charge Toggle – promises to manage charging protocols, but doesn’t work on all devices.
We recommend avoiding third-party utilities to change system settings, especially if you don’t have root access experience, instead using built-in MIUI or ADB tools as described above.
💡
If you often leave your phone charging overnight, set a charge limit of up to 80% through the MIUI settings (Settings → Battery → Charging Optimization) that will significantly extend the battery life.
5. Consequences of turning off fast charging: pros and cons
Before you make a decision, weigh the pros and cons. Disabling fast charging has both advantages and disadvantages:
| Advantages | Deficiencies |
|---|---|
| ✅ Reduced phone heat during charging | ❌ Increased full charge time (c) 1 hourly 2-3 hours) |
| ✅ Extension of battery life (less than deep discharge cycles) | ❌ There may be failures when using non-original chargers |
| ✅ More stable phone operation at high loads during charging | ❌ Some firmware may automatically enable fast charging after an update |
| ✅ Less wear on the connector USB-C induced | ❌ In some cases, you will have to repeat the disconnection procedure after resetting the settings. |
Critical moment: at Poco F3 firmware MIUI 13 Disabling fast charging through the engineering menu can be reset after restarting. ADB-team.
If you use your phone intensively and often need to recover quickly, it may be best to leave the function on but keep track of the temperature of the device.For those who charge the phone predominantly at night or keep it connected for a long time, turning off fast charging would be a smart solution.
6.Alternative ways to extend the life of the battery
Turning off fast charging isn’t the only way to keep the Poco F3 battery in good condition, but here are some additional recommendations:
- 🔄 Avoid full discharge: try to recharge your phone when the charge drops to 20-30%, Not waiting until he's fully seated.
- ☀️ Control the temperature: Do not leave the device in the sun or near heat sources, especially while charging.
- 🔌 Use original accessories: unoriginal cables and power supplies can damage the battery and charging system.
- 📵 Turn off unnecessary features: Turn off Wi-Fi, Bluetooth and mobile data when charging if they are not needed.
- 🔋 Battery calibration: once in a while 2-3 Make a full month of the cycle of discharge-charging (from 0% before 100%) controller-calibration.
Also note the optimised charging feature in MIUI. It automatically limits the charge to 80% and completes the process before waking up (if you have specified alarm clock times), which is one of the most effective ways to extend the battery life without manual settings.
💡
Turning off fast charging is most important for users who keep their phone charging for more than 2-3 hours at a time. For short sessions (30-60 minutes), overheating is usually not critical.
7. Frequent mistakes and how to avoid them
When trying to turn off fast charging, users often face typical problems, and here are the most common ones and ways to solve them:
- ❌ Impossible to find option in settings: Check version MIUI — In older builds (below 12.5), the function may not be available. Update the firmware through Settings → Updating the system.
- ❌ Engineering menu not open: Make sure you use the standard Phone app, not duplicate programs (like Google Phone.
- ❌ ADB Does not see the device: Install official Xiaomi drivers for your model. Enable debugging by USB Confirm your trust in the computer on your phone screen.
- ❌ After the reboot, fast charging is turned on again: This means the changes were not saved at the system level. ADB or use root-access applications (at your own risk).
If none of these methods worked, your firmware may have limitations from the manufacturer, which leaves you either to accept fast charging or to consider custom firmware (like LineageOS) that is more flexible.
