How to disable fast charging on Xiaomi Redmi Note 10S: all the ways and consequences

Why do users want to turn off fast charging on the Redmi Note 10S?

Xiaomi Redmi Note 10S is equipped with 33W fast charging technology, which allows you to recover 100% of battery power in about 60-70 minutes. However, not all users are happy with this feature, the main reasons for wanting to turn it off are overheating of the device, accelerated battery wear and even inconvenience (for example, when the phone is very hot in the hands while playing or watching video).

The manufacturer claims that fast charging is safe with built-in temperature and current controllers, but experience shows that when used intensively, the Redmi Note 10S can heat up to 45-50 ° C, which causes discomfort. In addition, some users note that after a year of active use, the battery capacity decreases by 15-20% - and blame it on accelerated charging.

In this article, we’ll look at all the ways you can turn off fast charging, from standard settings to hidden engineering menu features, and see what the implications are for your battery and smartphone performance, and whether it’s worth doing.

Method 1: Disconnect via standard MIUI settings

The easiest and safest method is to use built-in MIUI options. Unfortunately, in the latest firmware versions for the Redmi Note 10S, the direct option to turn off fast charging may not be available, but it can be activated through a hidden battery menu.

Instructions:

• 📱 Open the Settings app.
• 🔋 Go to Battery and Performance section.
• 🔍 Slap the icon. ⚙️ (Battery settings) in upper right corner.
• 🔌 If the option Quick charging is available - move the slider to the off position..

If there is no quick charge, try an alternative route:

1. Press your finger on the battery screen (where the percentage of charge is displayed) and hold for 5-7 seconds.
2. A hidden menu will appear with the option to Limit charging current - select it.
3. Set the limit at 10W (standard charging).

Charge your phone to 30-50% (to avoid abrupt shutdown)

Connect the original cable (low-quality cables can reset settings)

Check the MIUI version (on old firmware, the menu may differ)

⚠️ Note: On some versions MIUI 13/14 This method may not work because of Xiaomi's policy of removing "extra" settings.

Method 2: Use of the MTK Engineer Mode

If the standard settings didn’t help, you can use the engineering menu, a hidden tool for deep customization of the hardware of the smartphone. Redmi Note 10S is built on a chip Mediatek Helio G95, so we need MTK Engineer Mode.

Step-by-step:

1. Download the MTK Engineer Mode app from Google Play.
2. Open the application and grant the rights to ADB (if requested).
3. Go to the Hardware Testing → Charging section.
4. Select Fast Charging and set the Disable value.
5. Save the settings and restart the phone.

📌 Important: After disabling fast charging via Redmi Note's engineering menu 10S will charge at speed ~5W–10W (This will increase the full charge time to 3-4 hours.

⚠️ Warning: Incorrect settings in the engineering menu may result in loss of warranty or damage to the power controller.Do not change other settings unless you are sure of their purpose!

Method 3: Limiting charging current through ADB

For power users, there is a method to disable fast charging via Android Debug Bridge (ADB), which requires a connection to a computer, but gives more control over the process.

What you need:

• 🖥️ Computer with installed ADB-driver.
• 📱 USB-cable (preferably original).
• ⚙️ Developer Mode on the phone.

Instructions:

1. Connect your phone to your PC and open the command prompt (Windows) or terminal (macOS/Linux).


2. Enter a command to check the connection:




adb devices




3. If the device is detected, perform:




adb shell




4. Enter a command to disable fast charging:




echo 0 > /sys/class/power_supply/battery/fast_charge_enabled




5. Reboot the phone.

🔹 Note: This command does not work on all versions MIUI. If you get a "Permission denied" error, the kernel is locked for such changes, and then only unlocking the bootloader and installing the custom kernel will help, but this will void the warranty.

adb shell settings put global battery_charge_limit 1

This command limits the charging current to a baseline level, but can reset after rebooting.-->

Method 4: Using Third-Party Applications

If you don't want to dig into settings or connect your phone to a PC, you can use specialized charging management apps. 10S:

📢 Important: Applications without ROOT-The rights (e.g. AccuBattery) can only monitor charging, but not block fast charging completely.

⚠️ Attention: Installation ROOT on the Redmi Note 10S voids the Xiaomi warranty and may result in the blocking of certain features (e.g. banking applications or other services). MIUI-Consider the risks before using this method!

Method 5: Hardware restriction (using a non-original charger)

If the software methods don't work, you can take a "circumvent" approach, which is to use a charger with less power.

• 🔌 Charging from an old smartphone (5W–10W).
• 💻 Charging through USB-port (2.5W–5W).
• ⚡ Using Power Bank with Current Restriction.

🔍 How does it work? - Redmi Note 10S It automatically determines the power of the charger and adjusts the charging current. 5W-Charging, the phone will charge in standard mode, without acceleration.

⚠️ Warning: Using substandard chargers can damage the power controller!Buy certified accessories (e.g. from Anker or Baseus).
