How to disable smart charging on Xiaomi: a complete guide for all versions of MIUI

Smart Charging in Xiaomi, Redmi and POCO smartphones was designed to extend battery life. The algorithm limits the charge to 80-90% at night, then up to 100% by the time the user wakes up. However, not everyone likes the phone deciding when and how to charge, especially when it is necessary to urgently collect full charge before the trip, and the system artificially slows down the process.

In this article, we’ll look at all the ways to turn off smart charging across the different versions of MIUI (12 to 14), including hidden settings and workarounds for models without an explicit menu option. You’ll also learn how the feature works at the firmware level, which models support it, and what to do if the phone doesn’t charge to 100% after deactivation.

What is Xiaomi Smart Charging and Why Turn It Off

Smart Charging is a software algorithm integrated into MIUI firmware that analyzes user habits and optimizes charging.

• 🔋 Limiting charge to 80–90% at night to reduce battery wear.
• ⏰ Up to 100% by your scheduled wake-up time (e.g. 7:00 if you usually get up at that time).
• 📊 Adaptation to the individual schedule of the user (if you go to bed at 23:00, the system remembers this and adjusts the charge).

According to Xiaomi, this strategy increases battery life by 20 to 30 percent by reducing battery life in a full-charge state.

• ⚡ Slow charging in critical situations (for example, when you need to quickly dial 100% before exiting).
• 🤖 Unpredictability: Sometimes the algorithm works even during the day if you have connected charging for a long time.
• 🔧 Difficulty shutting down on some models (especially budget Redmi and the Redmi). POCO).

Turn off the smart charging is worth it if:

⚠️ Note: On devices with a battery capacity of less than 4000 mAh (for example, Xiaomi 11 Lite or Redmi Note) 10S) Disabling smart charging can lead to accelerated battery degradation at frequent cycles of 0-100.

Official method: disabling through MIUI settings

On most Xiaomi devices (especially the flagship Mi series, Xiaomi 12/13/14 and some Redmi Notes), the smart charging option is available right on the menu.

1. Open Settings → Battery and Performance.
2. Select Battery Settings (or Battery Status in older versions of MIUI).
3. Find the Smart Charging item and move the slider to the Off position.

If there is no such item, try an alternative path:

Settings → Additional → Special features → Battery optimization

On some devices (such as the POCO X3 Pro or Redmi 9), the option may be hidden under a different name:

If you didn't find an option on the menu, it doesn't mean it's not there, it may be hidden because of regional firmware or the MIUI version, and one of the alternative methods described below will help.

Hidden settings: how to turn on the developer mode

On some devices (especially those with MIUI 12.5 and later), the smart charging option is hidden in the developer menu to activate it:

1. Go to Settings. → The phone.
2. Find the MIUI version and tap it 7 times in a row.
3. Enter a password/pattern lock if required.
4. Return to the main settings – a new item for developers will appear.

Now, follow the following steps:

Settings → For developers → Battery optimization → Smart charging (disable)

If the developer menu does not have this option, try to find:

• 🔄 Reset adaptive charging (on some devices, this resets the algorithm settings).
• 📊 Battery logs → There might be a slider adaptive charge.

Important: After you turn off smart charging via the developer menu, some models (such as the Xiaomi 12S Ultra) can automatically turn it back on after the MIUI update. In this case, you will have to repeat the procedure or use the method with ADB (described below).

Check out the MIUI version (Settings → About the phone)

Activate Developer Mode (7 taps according to MIUI)

Connect the device to charge (some options are only active when charging)

Make a backup of settings (Settings) → System system → Backup)-->

Disconnection through ADB: for experienced users

If your firmware doesn’t have a visual option to turn off smart charging, you can use the ADB (Android Debug Bridge) commands, which works on all Xiaomi devices but requires a connection to a computer.

You'll need:

• 🖥️ Computer with installed ADB-tool.
• 📱 Included Developer Mode and Debugging by USB phone-on.
• 🔌 Cable USB Type-C (preferably original).

Step-by-step:

1. Connect the phone to the computer and allow debugging over USB (a request will appear on the smartphone screen).
2. Open the command prompt (cmd on Windows or Terminal on macOS/Linux) and type:

adb shell


settings put global smart_charging_enabled 0

If the first command fails, try the alternative:

adb shell


settings put global battery_charge_control_enabled 0

To check if changes are applied, enter:

adb shell settings get global smart_charging_enabled

If the answer is 0, the smart charging is turned off.

⚠️ Note: On some devices (e.g. Redmi) K50 Gaming after use ADB protection may work MIUI, And the phone will require unlocking the bootloader to apply the changes, and it will result in a complete data reset. ADB If the teams don't work? ADB Not applicable, try: 1. Update MIUI Up to the latest version (some firmware is blocked) ADB-2. Use an alternative method with file editing build.prop (requires root rights). 3. Install custom recovery (TWRP) And turn off the function through Magisk modules.Back-off: how to make the phone charge to 100% without turning off the function If you do not want to completely turn off smart charging, but sometimes you need to quickly dial 100%, use these tricks: ⏱️ Change wake time: Set your alarm 1–2 hours early and your phone will bring the charge to 100% by that time. 🔄 Reboot the device: Sometimes after a reboot, the algorithm is reset and the charge goes to the maximum. 📴 Disconnect and connect charging: Physical disconnection of the cable for 10-15 seconds can “cheat” the system. 🔋 Use a different charger: Some models (e.g. Xiaomi 11 Lite) NE) They ignore smart charging when connected to sources with power over 30 watts. Another working method is to turn on the plane mode for 5-10 minutes while charging, which interrupts the background processes, and the phone can continue charging up to 100%. But once you've gone out of airplane mode, the algorithm can be activated again. MIUI 14, the option Fast Charging to 100% on the battery menu has been introduced, and it temporarily turns off the restrictions for 2 hours, after which the smart charging is activated again. 💡If your Xiaomi is constantly limiting charge to 80% even after you turn off smart charging, check the Security app settings. Sometimes there is a separate Battery Protection item that duplicates the function. What to do if the smart charging does not turn off If none of the methods worked, the problem may be related to the problem: 🔄 Regional firmware: On devices for China (CN ROM) Some battery settings are blocked. 📦 Update MIUI: After the firmware update, the settings can be reset. 🛠️ Damage to system files: For example, after a failed root access. Here's what you can do: Reset your battery settings: Settings → Annexes → Application management → Three dots (menu) → Reset the battery settings Set custom recovery (e.g, TWRP) and edit the file. /system/build.prop, line: persist.vendor.battery.charge_control_limit=100 Requires root rights! Refuse the device to the global version MIUI (for example, CN ROM Globally ROM). If the problem persists, check the battery status through the engineering menu: ##4636## → If the value of health differs from Good, it is possible that the battery is worn out and the system forcibly limits the charge. 💡On devices with an unlocked bootloader, smart charging can be permanently disabled via Magisk modules (such as Smart Charging Disabler).However, this voids the warranty and can lead to problems with the device. OTA-update. Many users fear that turning off smart charging will lead to rapid battery degradation. Let's see how justified this is. According to Battery University research, lithium-ion batteries degrade faster when they are degraded: 🔥 High temperature (above 30)°C). ⚡ Extended stay of 100% (especially under stress). 🔄 Deep discharges (below 20%) and smart charging is fighting the second point, but turning it off doesn't guarantee quick battery death if you follow simple rules: 🌡️ Avoid overheating (do not play heavy games while charging). 🔌 Don’t keep your phone on charge all night (turn off after 100%). 🔋 Try to keep your battery in the 30-80 percent range of everyday use. Use apps like AccuBattery or the built-in Settings menu to check battery wear. → Battery → Battery status. If the capacity has fallen below 80% of the original, you should think about replacing the battery.
