How to Reset Your Battery Settings on Xiaomi: 3 Proven Ways

Why Xiaomi Smartphones Are Drying Quickly and When You Need a Battery Reset

Have you noticed that Xiaomi started to run out in a few hours, even though it used to hold a charge all day? Or after the MIUI update, the percentage of charge jumps from 50% to 20% per minute? The reason most often lies in a failure of the calibration of the battery, a system that tracks the real level of battery charge. Resetting the battery helps to return accurate readings and restore the normal operation of the device.

The manufacturer doesnโ€™t advertise this feature, but itโ€™s in all MIUI-based smartphones, from the budget Redmi Note to the flagship Xiaomi 14. The reset doesnโ€™t delete your data (photos, contacts, messages), but it resets battery usage statistics, resets app restrictions, and restarts power-saving algorithms, which is especially useful after:

  • ๐Ÿ”„ Updates MIUI Up to the new version (for example, 13 to 14)
  • ๐Ÿ”‹ Replacement of the battery (even the original one)
  • ๐Ÿ“ฑ Severe overheating or discharge to 0%
  • ๐Ÿ› ๏ธ Installation of custom firmware or root rights

Itโ€™s important to understand the difference: resetting battery settings โ‰  The first method is software-based and takes 5 minutes, the second requires a full discharge/charging cycle (which we will discuss at the end of this article). MIUI.

Method 1: Reset via the Battery and Performance menu (no root)

This is the official method that works on all Xiaomi, Redmi and POCO smartphones with MIUI 12 and later. It does not require superuser rights and is suitable even for beginners.

  1. Open Settings โ†’ Battery and Performance.
  2. Slip on the three points in the upper right corner and select Reset Battery settings (on some firmware, the item is called Battery Optimization โ†’ Reset settings).
  3. Confirm the action by clicking Reset in the pop-up window.
  4. Reboot your smartphone (required!).

After the reboot, the system will start collecting new battery usage statistics, the first 1-2 days the charge can jump, which is normal, and to speed up the calibration process, complete the full discharge cycle (up to 0%) and charging (up to 100%) without interruption.

โš ๏ธ Note: On some models (e.g, POCO F5 or Redmi K60) The reset point is hidden. If it's not there, go to Method 2 through the engineering menu.

Method 2: Reset via engineering menu (#4636##)

The engineering menu is a hidden section of Android that has low-level settings.

  1. Open the Phone app and type the combination: ##4636## (some firmware may require ##6484##).
  2. Select the Battery Information tab.
  3. At the bottom of the screen, find the Battery Reset button and press it.

If there is no reset button, try an alternative path:

  • ๐Ÿ“ฑ Go to Settings. โ†’ The phone. โ†’ Tap 7 times on the version MIUI, activate the developer mode.
  • ๐Ÿ”ง Back to Settings โ†’ Additionally. โ†’ For developers โ†’ Turn on Debugging. USB.
  • ๐Ÿ”Œ Connect your phone to your PC and use Method 3 (ADB).
What to do if the engineering menu is not opened?
On some firmware (e.g., global versions for Europe), access to ##4636## is blocked. In this case: 1. Install the MTK Engineering Mode app from the Play Market (for MediaTek processors only). 2. Or use Activity Launcher (free) to manually run the hidden menu com.android.settings.TestingSettings.

After resetting through the engineering menu, it is recommended:

  • ๐Ÿ”„ Reboot the phone.
  • ๐Ÿ“Š Run the battery test in the Mi Battery Doctor app (download in GetApps).
  • โšก Disable Smart Charging in Battery Settings (It May Interfere with Calibration).

Method 3: Reset via ADB (for advanced users)

If the first two methods fail, the ADB (Android Debug Bridge is a tool for debugging Android through a computer, USB-cable and enabled debugging by USB. Step-by-step instruction:

  1. Download Platform Tools (the official package from Google) and unpack into any folder.
  2. Turn on the phone Debugging over USB (Settings โ†’ About Phone โ†’ 7 times tap on the MIUI version โ†’ return to Additional โ†’ For developers).
  3. Connect Xiaomi to your PC, select File Transfer mode and confirm debugging permission.
  4. Open the Windows command line or the Mac/Linux terminal in the Platform Tools folder and type in: adb shell dumpsys battery reset
  5. Reboot your phone with the command: adb reboot

If the dumpsys battery reset command does not work, try an alternative:

adb shell


su




echo 1 > /sys/class/power_supply/battery/reset_capacity




exit




exit

(requires root rights!)

โš ๏ธ Attention: Wrong commands ADB If you're not sure, use Method 1 or contact a service center.

๐Ÿ’ก

Before using ADB, check if your Xiaomi PC recognizes your device. Type the adb device command and the device name should appear on the list.

What to do if the reset did not help: additional steps

If the battery is still running out too quickly after reset, or if the percentage of charge is "jumping," the problem may be deeper.

Symptoms.Possible causeDecision
Charge drops 10-20% in 5 minutesFailure of the battery controllerReplacement of the battery in the service
The phone is turned off at 30-40%Battery wear (>500 cycles)Checking the settings โ†’ Battery โ†’ Status
Heating during chargingUnoriginal cable/chargingUse branded RAM (for example, Xiaomi 33W)
Quick discharge on standbyBackground activity of applicationsLimit background work in battery settings

If you suspect physical wear of the battery, check its condition:

  1. Go to Settings โ†’ Battery โ†’ Battery status.
  2. Compare the current capacity with the passport (for example, 4500 mAh vs 5000 mAh).
  3. If the capacity has dropped below 80%, it is time to change the battery.

๐Ÿ’ก

Resetting the battery only helps with software failures, and if the problem is physical wear (blown, loss of capacity), you need to replace the battery.

How to Calibrate Your Battery After Resetting

Resetting is just the first step, so that the battery can get the exact percentage of charge, you need to calibrate it.

  1. Full discharge: Use your phone before automatically switching off (0%).
  2. Charging without interruptions: Connect the original RAM and charge up to 100% without turning off (even if the phone shows 100%, hold another 1-2 hours).
  3. Recycle: Discharge to 0% and recharge to 100%, which will help the battery controller to remember the real boundaries.

To speed up the process:

  • ๐ŸŽฎ During the discharge, run a resource-intensive application (for example, a Genshin Impact game or a test). 3DMark).
  • ๐Ÿ”Š Enable maximum screen brightness and video playback.
  • ๐Ÿ“ถ Turn off Wi-Fi and mobile data to avoid background activity.

After calibration, avoid:

  • โŒ Frequent recharging "a little" (it is better to charge from 20% to 80%).
  • โŒ Using your phone while charging (especially playing games).
  • โŒ Overheating (do not leave the device in the sun or near heat sources).

Frequent Mistakes and How to Avoid Them

Many users make the same mistakes when resetting their batteries, which makes things worse.

โš ๏ธ Note: Never interrupt the process of resetting through ADB Or an engineering menu! This can cause the power controller to crash and the phone to completely discharge in minutes.

  • ๐Ÿšซ Reset battery settings more than 1 time every 3 months.Frequent resets knock down algorithms MIUI, The phone starts to โ€œlearnโ€ again, wasting excess energy.
  • ๐Ÿšซ Use non-original batteries, cheap ones may not support calibration and may show the wrong percentage of charge.
  • ๐Ÿšซ Charge the phone overnight. After 100%, the battery continues to receive current, which accelerates wear (use Adaptive Charging in the battery). MIUI).

If the battery is discharged even faster after reset, check:

  • ๐Ÿ” Background activity: In Settings โ†’ Battery โ†’ Battery usage see which apps are spending the most.
  • ๐Ÿ” Optimization: Enable Power Saving Mode for resource-intensive applications (e.g. TikTok or Google Maps).
  • ๐Ÿ” Temperature: If the battery is heated above 40ยฐC is a sign of a malfunction.

FAQ: Answers to Frequent Questions

Will the battery reset delete my data (photos, contacts)?
No, battery resets only affect system settings related to power consumption. Your files, applications, and settings remain intact.
My Xiaomi doesn't have a battery reset. What do I do?
Possible reasons: You have an older version of MIUI (update via Settings โ†’ Software Update). The firmware is modified (e.g. custom xiaomi.eu). Try Method 2 or Method 3. The manufacturer has hidden the item for your model (e.g., on the POCO M6 Pro). Use ADB.
After the battery was discharged, it started to run out even faster. Why?
This is a temporary phenomenon. After a reset, MIUI begins to re-collect usage statistics, and the first 1-2 days of energy consumption may be higher than usual. Give the system a 3-4 charge/discharge cycle to stabilize. If the problem persists: Check battery wear in Settings โ†’ Battery โ†’ Status. Remove unused applications (they can work in the background). Reset to factory settings (pre-save data!).
Should I calibrate the new battery after replacement?
Yes, you must! The new battery has different characteristics, and the battery controller must learn to display the percentage of charge correctly. Perform: Reset the battery settings (Method 1). 3 complete discharge/charging cycles (0% โ†’ 100%) This will help avoid charge surges and premature wear.
Can I drop the battery on Xiaomi without a computer?
Yes, the first two methods (via the MIUI menu and the engineering menu) don't require a PC. ADB only needs to be used if the standard methods didn't work. If the engineering menu is blocked, try: Install the MTK Engineering Mode app (for MediaTek processors). Use Activity Launcher to run hidden settings.
