How to turn off accelerated charging on Xiaomi Redmi: 5 ways + battery tips

Accelerated charging in Xiaomi Redmi smartphones is a convenient feature that allows you to restore battery power in minutes. However, not all users want to use it constantly. Some are worried about the battery life, some are facing overheating of the device, and some just do not like how quickly the phone discharges after a turbo-recharge. In this article, we will discuss all possible ways to turn off fast charging on the Redmi Note, Redmi (series without consoles) and other models of the brand – from standard MIUI settings to hidden engineering menus.

It's important to understand that the process of shutting down can vary depending on the firmware version and device model. We've tested the instructions on the Redmi Note 10 Pro, Redmi 9T, Redmi K50 and other popular devices, so you can tailor the steps to your version. In the article, you will also find a table of methods compatibility with different models and answers to frequent questions about the effect of accelerated charging on the battery.

If you’ve never looked into your Xiaomi battery settings, prepare for the fact that some menu items may be hidden. Don’t worry, we’ll show you how to open them without root rights or complex manipulation. And for those who like experimentation, we’ve added an ADB shutdown (no warranty risk!).

Why do users want to turn off accelerated charging?

At first glance, fast charging seems like the perfect solution: in 30 minutes, 50-70% of the battery is available, and you can run around. But there is a downside to this technology that manufacturers prefer not to mention. Here are the main reasons why Xiaomi Redmi owners are looking for a way to deactivate it:

• 🔋 Battery degradation: Lithium-ion batteries wear out faster at high charging currents. Research suggests that the constant use of turbo mode can shorten battery life. 15-20% through 1-1.5 active-year.
• 🔥 Overheating of the device.Many Redmi Note users 11 Pro+ redmi K40 They complain that the phone is heating up. 40-45°C during charging, which is not only unpleasant but potentially dangerous for internal components.
• ⚡ Power failure: In some regions with frequent power surges, accelerated charging can cause power controller failures, especially on low-end models like the Redmi. 9A.
• 📉 Uneven discharge. After fast charging, many people notice that the phone discharges with "steps": it quickly loses at first. 20-30%, Then it lasts a long time, and at the end again "falls" to zero.

Of course, Xiaomi is introducing protection against these problems: new models have temperature control and current control systems, but if you are one of those who prefer a “careful” mode of operation, turning off accelerated charging can be a reasonable trade-off between speed and durability.

Method 1: Standard MIUI settings (the simplest method)

On most modern Xiaomi Redmi smartphones (starting with MIUI 12), the accelerated charging disabling feature is put into the basic settings. This method does not require root rights or additional programs, but is not available on all models.

1. Open the Settings app (cog on the desktop).
2. Go to the Battery and Performance section.
3. Select Battery Settings (or Charge on some firmware).
4. Find the option Accelerated Charging (can be called Quick Charging, Turbo Charging or Quick Charging).
5. Move the slider to the off position. or uncheck the tick.

If there is no such item, don’t be upset, which means your model doesn’t support software shutdown via the menu, in which case you can move on to the following ways. Also note that on some devices (such as the Redmi Note 8 Pro), the option may be hidden behind additional settings:

Important: After cutting off accelerated charging, the phone will charge in standard mode (usually 5V/1A or 5V/2A).The full charge time can increase from 1-1.5 hours to 3-4 hours depending on the battery capacity.

Method 2: Engineering menu (for advanced users)

If you don't have a shutdown option in the standard settings, you can try it through the engineering menu. This method works on most Xiaomi Redmi devices, but you need to be careful - doing the wrong thing can cause your phone to crash. Here's a step-by-step instruction:

1. Open the Phone app and enter the combination: ##4636##.
2. In the menu that appears, select Battery Information (or Battery Information).
3. Scroll down and find Fast charge or Quick charge.
4. Click on it and select Disable.
5. Restart the device so that the changes take effect.

On some models (e.g. Redmi 10 or Redmi Note 11), the path may be different:

• Instead of ##4636##, try entering ##6484## (the hardware testing menu).
• In the engineering menu, you may need to select MTK Settings (for MediaTek devices) or Qualcomm Settings (for Snapdragon).
• On some firmware, the option is hidden behind Factory mode → Charging settings.

💡

If the engineering menu doesn't open, check if it's blocked by antivirus or fraud protection in the MIUI security settings. Try temporarily disabling these options.

⚠️ Note: Changes to the engineering menu may reset after updating the firmware. It is also not recommended to turn on / off other options in this menu without understanding their purpose - this can lead to unstable operation of the device.

Method 3: Use ADB-commands (without root rights)

If previous methods have failed, you can disable accelerated charging using ADB (Android Debug Bridge), which does not require superuser rights and is suitable for most Xiaomi Redmi models based on MIUI 11 and later.

1. Download and install. ADB-driver on your computer.
2. Turn on USB Debugging on your phone: Settings → About Phone → MIUI version (stamp 7 times to become a developer), then go back to Settings → Additional → For Developers and activate debugging.
3. Connect your phone to your PC via USB (select File Transfer Mode).
4. Open the command line (Windows) or terminal (macOS/Linux) in the folder with the platform-tools.
5. Enter the command to check the connection: Adb devices Make sure your device appears in the list.
6. Execute the command to disable fast charging: adb shell settings put global fast_charge 0
7. Reboot the phone.

To return accelerated charging, use the same command by substituting 0 for 1:

adb shell settings put global fast_charge 1

This method works on most devices, but there are exceptions, such as the Redmi K30 Pro and some other models may require an additional command to reset the power controller:

adb shell dumpsys battery reset

💡

ADB-commands are one of the most reliable ways to disable accelerated charging, because changes are made at the system level, but after resetting the settings or updating the firmware, you may need to repeat the procedure.

Method 4: Special Applications (for root users)

If you have root rights, the process of turning off accelerated charging becomes easier and more flexible. There are several applications that allow you to control charging parameters at a low level.

• 📱 AccuBattery - not only disables fast charging, but also monitors battery health. - Xiaomi Redmi MIUI HyperOS.
• ⚡ Quick Charge Switch – a specialized application for managing charging protocols (requires Magisk or SuperSU).
• 🔧 Kernel Adiutor – allows you to fine-tune the parameters of the core, including current and voltage restrictions.

Example of settings in AccuBattery:

1. Install the app from Google Play.
2. Provide root access when requested.
3. Go to the Charging section.
4. Activate the option to Limit the charging current and set a value of 1000 mA (or less for even more gentle mode).
5. Save the settings and restart the device.

⚠️ Note: Using root rights voids Xiaomi’s warranty and can cause system instability if you change critical settings.

If you don't want root rights, but you still want to be flexible, consider using Magisk modules. For example, the Fast Charge Disabler allows you to turn off accelerated charging without making deep changes to the system.

Method 5: Hardware shutdown (for power users)

If the software methods don't work, or if you want to guarantee that you can turn off fast charging, you can take a radical step of limiting power to the level of the charger or cable.

• 🔌 Use a non-original power supply. Most of the "non-original" chargers (especially cheap ones) don't support Xiaomi's Quick Charge (Turbo Charge) protocols, like the old iPhone's power supply (5V/1A) charge your Redmi in standard mode.
• 🔗 Cable without fast charging support. USB-cables (especially long or cheap) don't have the necessary conductors to transmit high current.
• 🔋 Many external batteries have a low current mode (e.g. Xiaomi Power Bank). 3 When holding the button, the mode is switched on 5V/1And).

You can also physically modify the charger, but it requires soldering skills and an understanding of electrical circuitry. For example, some Xiaomi power units can re-sweeten the resistor responsible for identifying the fast charging protocol, but we do not recommend this method because of the risk of damage to the device or fire.

If you decide to go the way of hardware restriction, consider the following nuances:

• Using non-original accessories can cause battery damage due to unstable voltage.
• Some Redmi models (such as the Redmi Note 12 Pro+) can block charging if they detect an “inappropriate” cable or power supply.
• Charging time will increase by 2-3 times, which can be uncomfortable on trips.
