How to turn off fast charging on Xiaomi Redmi Note 10T: all ways

The Xiaomi Redmi Note 10T features fast charging technology (up to 33 watts), which allows you to restore battery power in minutes. However, this advantage has the downside: accelerated charging increases battery heat and reduces its life by 15-20% during heavy use. If you notice that the phone overheats during charging or the battery has become worse, turning off fast charging may be the solution.

In this article, we will explore all the available ways to deactivate the function, from standard settings to hidden features of the engineering menu. You will also learn how to check the current charging mode and what alternatives exist for gentle energy recovery. 10T base MIUI 12/13/14 HyperOS.

Why you should turn off fast charging on the Redmi Note 10T

Xiaomi’s Fast Charge technology is implemented by increasing current and voltage, which speeds up the process but puts additional strain on the lithium-ion battery, and here are the key reasons why users prefer to turn it off:

• 🔥 Overheating of the case - with rapid charging, the battery temperature can rise to 40-45°C, which adversely affects its capacity.
• 📉 Battery degradation – each accelerated charging cycle reduces the total battery life by 0.1–0.3%, and in 2-3 years, this can lead to a capacity reduction of 30% or more.
• ⚡ Unstable power supply – in regions with frequent voltage surges, fast charging can cause failures in the power controller.
• 🛌 Night charging – if you leave your phone on charge all night, keeping high current constantly worsens battery health.

Xiaomi says that modern batteries are designed for 800-1000 charging cycles, but this value is true in standard mode (5V/2A). Using fast charging reduces this figure by 20-25%. If you plan to use a smartphone longer than 2-3 years, switching to normal mode will help to maintain battery capacity.

⚠️ Warning: Turning off fast charging doesn't guarantee eternal battery life, but it slows down wear. If the battery is already swelling or has lost more than 50% of its capacity, the only solution is to replace it.

Method 1: Disconnect via standard MIUI settings

The easiest way is to use the built-in options. In MIUI 12-14 and HyperOS, the path to settings may vary slightly, but the general logic is maintained.

1. Open the Settings app (the gear icon on the home screen).
2. Go to the Battery and Performance section.
3. Select Charging (in some versions – Charging settings).
4. Find the option Fast Charge or Turbo Charge and switch the slider to the off position.
5. Confirm the action if the system requests permission.

After that, the phone will charge in standard mode (5V/2A). Full charging time will increase from 1-1.5 hours to 2.5-3 hours, but battery heating will decrease by 30-40%.

If your MIUI version doesn’t have a separate fast-charging switch, try an alternative path:

1. Open the Settings. → The phone.
2. Tap 5-7 times on the MIUI version to activate the developer mode.
3. Return to the main settings menu and select Additional → For developers.
4. Find the option to limit charging current and set a value of 500 mA or 1000 mA.

⚠️ Note: Some firmware may not have charging current restriction. Don't confuse it with background restriction, which is another feature.

Method 2: Use of an engineering menu (for power 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 disrupt the phone.

Instructions:

1. Open the Phone app and enter the combination: ##4636##.
2. In the menu that appears, select Battery Information.
3. Scroll down and find Fast Charge Config or Charge Control.
4. Select Disable or Standard Charge (5V/2A).
5. Save the changes and restart the phone.

If the #4636### combination doesn’t work, try the alternative codes for Xiaomi:

• ##6484## - Hardware test (select Battery)
• #64663## is an extended battery menu.

After changing the settings in the engineering menu, be sure to restart the phone, otherwise the changes may not take effect. If after the reboot, fast charging is activated again, then the firmware resets the settings - in this case, only root access or third-party applications will help.

Method 3: Disconnect via ADB (without root rights)

If the standard methods don’t work, you can use Android Debug Bridge (ADB) — It's a tool for debugging Android devices, and it doesn't require super-user rights, but it requires a computer and a computer. USB-cable.

Step-by-step:

1. Download and install ADB Tools on your computer.
2. Activate the developer mode on your phone: Settings → About Phone → MIUI version (shap 7 times).
3. Turn on USB debugging in the Developer Menu.
4. Connect the phone to the PC and type in the command line:

adb shell


settings put global fast_charge 0

Once you've completed the command, restart your phone. To return the fast charge, use:

settings put global fast_charge 1

If the team doesn’t work, try an alternative:

adb shell


setprop persist.sys.fastcharge false

💡

Before using ADB, check that the phone has enabled the option to Allow USB Debugging in the developer menu. If you connect to a device, confirm it.

⚠️ Note: Some Xiaomi firmwares block changes through ADB. If permission denied error appears after entering the command, then root rights will be required.

Method 4: Third-party applications for charging management

If you don't want to mess with settings or ADB, you can use specialized applications that not only turn off fast charging, but also set a charge limit (for example, up to 80%), which prolongs the life of the battery.

Top.-3 apps for Redmi Note 10T:

• 📱 AccuBattery monitors battery status and allows you to limit charging current.The free version has limitations, but basic features are available.
• ⚡ Battery Charge Limit – sets a charge limit (e.g. 80%) and disables fast charging. Requires root rights for full functionality.
• 🔧 3C Toolbox is an advanced power management tool that allows you to configure charging profiles and disable Quick Charge.

Example of settings in AccuBattery:

1. Install the app from Google Play.
2. Go to Charge and activate the option to limit current.
3. Set the maximum current value at 1000 mA (1A).
4. Enable notifications about battery overheating (threshold - 35 ° C).

It should be borne in mind that third-party applications can conflict with the system services MIUI. If after installing the phone began to slow down or quickly discharge, delete the program and use another method.

💡

Third-party apps are effective, but they don’t guarantee 100% results, and on some Xiaomi firmware, they may not work as well because of the manufacturer’s limitations.

How to check if fast charging is actually off

After applying one of the methods, it is important to make sure that the changes have taken effect.

• ⚡ Indicator on the lock screen – when connecting the charge, the inscription “Fast Charge” or “Turbo Charge” should disappear.
• ⏱️ Charging time – if the phone was charged in 1 hour, now the process should take 2.5-3 hours.
• 🌡️ Body temperature - after 30 minutes of charging, check the battery heating (should not be higher than 30-35)°C).
• 📊 Ampere app shows the actual charging current. When fast charging is turned off, the value should be between 500 and 1000 mA.

For accurate diagnosis, use Ampere:

1. Install the app from Google Play.
2. Connect the phone to the charger.
3. Run Ampere and see the value. CHARGE (ma):

If the Ampere still shows high current values after the fast charging is turned off, then the settings did not apply, in which case try another method or check the compatibility of the charger.

What to do if nothing helps

If none of these methods worked, the reason may be as follows:

• 🔄 The firmware resets the settings - some versions MIUI Automatically return charging parameters to factory after restart.
• 🔌 Unoriginal charger – Cheap adapters can ignore phone restrictions and deliver high current.
• 🛠️ Damaged power controller – if the phone survived a fall or moisture, the charging control chip could fail.
• 🔒 Operator restrictions – on some firmware (for example, from MTS or Beeline) charging functions are blocked.

Decisions:

1. Update the firmware to the latest version through Settings → System Update.
2. Use the original Xiaomi charger (MDY-11-ED model for 33W).
3. Reset the settings to factory (pre-reverse the data).
4. Contact the service center if you suspect a hardware malfunction.

If you're willing to take drastic measures, you can get root rights and manually edit the system files that charge, but that voids the warranty and can cause the phone to malfunction.
