How to disable Quick Charge on Xiaomi: all the ways and consequences

Quick Charge has become the standard for most Xiaomi smartphones, including the Redmi line, POCO and flagship models.The technology allows you to recover up to 50-70% of charge in 30 minutes, but this advantage has the flip side: accelerated battery wear, overheating of the device and reducing the overall battery life. If you notice that the phone is very hot during charging or the battery has become worse — perhaps consider turning off fast charging.

In this article, we’ll look at all the current ways to disable Quick Charge on Xiaomi devices running MIUI 12-14, including hidden developer settings and alternative methods. You’ll also learn which models support this feature, how to check the current charging mode and what to do if standard methods don’t work. It’s important to understand that turning off fast charging is not a panacea, but one of the battery life extension tools that should be combined with other battery care measures.

Why you might want to turn off Quick Charge on Xiaomi

Fast charging technology relies on increasing current and voltage, which inevitably leads to two problems: heat generation and battery degradation. Manufacturers claim that modern lithium-ion and lithium-polymer batteries are designed for such loads, but practice shows: With intensive use of Quick Charge, the battery capacity can decrease by 15-20% through 1,5-2 year-end.

The main reasons why Xiaomi users decide to turn off fast charging are:

• 🔥 Overheating of the device during charging (especially when using resource-intensive applications at the same time).
• 📉 Rapid decrease in battery capacity – if the phone is discharged 30-40% For several hours without active use.
• ⚡ Use non-original chargers that are not optimized for Quick Charge.
• 🛌 Night charging – if you leave your phone charging all night, fast charging in the first hours can do more harm.
• 🔋 The desire to extend the battery life 2-3 year by reducing the burden.

Importantly, turning off Quick Charge does not guarantee eternal battery health, but it can slow down battery degradation, for example, tests show that when fast charging is turned off and operating rules are followed (do not allow discharge below 20% and charge above 80%), the Xiaomi battery lasts 25-30% longer.

What Xiaomi models support Quick Charge

Not all Xiaomi smartphones allow you to manually disable fast charging, depending on the version of MIUI, hardware platform and manufacturer's policy. Below is a table with models that have proven the method to work (data is relevant for MIUI 12-14):

If your model is not listed, it doesn’t mean that you can’t disable Quick Charge. On some devices, the option is hidden and requires activation via ADB or third-party utilities. For example, on Redmi Note 9 Pro and POCO X3 NFC, the only way to disable Quick Charge is through the build.prop file editing, which requires an unlocked bootloader and root rights.

⚠️ Note: On devices with MediaTek processors (e.g. Redmi) 10C, POCO M4 Pro) disabling Quick Charge through the developer settings may cause the charging module to malfunction. In this case, alternative methods are recommended (see section below).

Method 1: Disconnect via developer settings (official method)

The safest and most recommended way is to use the developer menu, which works on most modern Xiaomi devices without having to root or unlock the bootloader. MIUI 12-14:

Activate Developer Mode (click 7 times on "Version") MIUI" on the telephone")

Connect the original charger

Charge your phone to at least 30%

Close all background applications-->

1. Open the Settings. → The phone.
2. Find the MIUI version and click on it 7 times in a row until the notification “You became a developer” appears.
3. Return to the main settings menu and open a new section of the Developer Settings (may be in the Additional or System).
4. Scroll down to the Network and Charging block (or Hardware Acceleration on some firmware).
5. Find the option to turn off fast charging (can be called Quick Charge, Fast Charging or Smart Charging).
6. Activate the switch and confirm the action.

Once turned off, the phone will charge in standard mode (usually 5V/1A or 5V/2A).To check that fast charging is indeed disabled, plug in the charger and look at the charging indicator: if you previously displayed "Fast Charging" or "Turbo Charging", now it should just be "Charging" or "Standard Charging".

⚠️ Note: On some devices (e.g. Xiaomi 12 Pro) after disabling Quick Charge through the developer settings, the option may be reset after the reboot, in which case you will need to re-activate it or use alternative methods.

💡

If the option "Disable Fast Charging" is not on the developer menu, try updating MIUI to the latest version, in some cases it appears after the update.

Method 2: Use the Hidden MIUI Optimization Menu (for advanced ones)

On devices with MIUI 13/14 firmware, there is a hidden MIUI Optimization menu that allows you to fine-tune system settings, including charging. This method does not work on all models, but it can be useful if the standard method does not work.

1. Open the Phone app.
2. Enter the combination: ##4636##
3. In the menu that opens, select MIUI Optimization (or Testing on some firmware).
4. Go to the Battery section.
5. Find the Fast Charge or Quick Charge Control option and turn it off.

If there is no MIUI Optimization menu, it means that your model does not support this method, in which case you can try an alternative method through ADB (see the next section).

Important: Changes to the hidden menu can affect the stability of the system. If after disabling Quick Charge, the phone began to restart or incorrectly display the charge level, return the settings to the original state.

Method 3: Disconnect via ADB (for power users)

If previous methods have failed, you can disable Quick Charge via Android Debug Bridge (ADB), which requires connecting your phone to your computer and basic command line knowledge, and the advantage of the method is that it works on most Xiaomi devices, including those where the option is hidden in the interface.

First, prepare everything you need:

• 💻 A computer with installed Xiaomi drivers and ADB (You can download it as part of Google’s Platform Tools).
• 📱 Smartphone with enabled debugging USB (developer-setting).
• 🔌 Original. USB-cable (preferably from the set).

Follow the instructions:

1. Connect the phone to your computer and confirm the permission to debug via USB.
2. Open the command prompt (cmd) in the folder with ADB.
3. Enter the command to check the connection: Adb devices Make sure your device appears in the list.
4. Execute the command to disable fast charging: adb shell settings put global fast_charge 0
5. Reboot the phone.

To return a quick charge, use the same command, replacing 0 with 1:

adb shell settings put global fast_charge 1

⚠️ Note: On some devices (e.g. Redmi) K50) team fast_charge In this case, try the alternative command: adb shell settings put global. miui_optimization_disable_fast_charge 1 But keep in mind that this can cause other functions to fail. MIUI.

💡

Disabling Quick Charge via ADB does not require root rights, but changes can be reset once the MIUI update is in place.

Method 4: Use of third-party applications (alternative)

If you are uncomfortable with ADB or your Xiaomi model does not have the option to turn off in the settings, you can use third-party applications.

• 🔧 AccuBattery, which allows you to limit charging current and monitor battery health, does not turn off Quick Charge completely, but reduces load.
• 📊 Battery Charge Limit – sets a charge limit (e.g. 80%), which indirectly reduces the harm of fast charging.
• 🔌 Quick Charge Disabler (requires root) – completely blocks fast charging at the system level.

Importantly, most apps without root rights can only limit charging, but not shut it down completely. For example, AccuBattery recommends setting an 80% limit and charging your phone with a slow charger (5V/1A), which has a similar effect.

If you are ready to get root rights, then you can completely disable Quick Charge through file editing /system/build.prop.

1. Get root with Magisk.
2. Open the build.prop file in the root editor (e.g., Root Explorer).
3. Add a line: persist.sys.qc_disable=1.
4. Save the changes and restart the phone.

⚠️ Note: Editing system files without root rights or through unverified applications can lead to a device blink.If you are not sure about your actions, use official methods (sections). 1-3).

What to do if Quick Charge is not turned off

If none of the methods described have worked, the problem may lie in the following:

• 🔄 Firmware MIUI modified (e.g. custom or regional) in which case the option may be removed or moved to another menu.
• 🔌 The charger does not support standard modes. Some power supplies (especially from third-party manufacturers) force fast charging to be activated.
• 📱 Hardware limitations: On budget models (e.g. Redmi A-series), fast charging can be implemented at the power controller level and cannot be software-operated.

In such cases, the following solutions can be tried:

1. Use a slow charger (5V/1A). Even if the Quick Charge remains on, the power supply without fast charging support will not be able to activate this mode.
2. Update MIUI to the latest version. Sometimes the option appears after the update.
3. Install custom firmware (like LineageOS or Pixel Experience) where charging management is more flexible.
4. In some cases, you can turn off Quick Charge via the engineering menu (available only from official partners).

On devices with a Snapdragon 8 Gen 1/2 processor (e.g. Xiaomi 12 Pro, Redmi K50 Gaming), Quick Charge shutdown can be blocked at the firmware level due to Qualcomm's integrated charging controller. In this case, the only reliable way is to use a slow charger or limit current through applications like AccuBattery.
