How to remove autobrightness on Xiaomi: all ways to turn off

The automatic brightness control on Xiaomi smartphones is a feature that should make life easier for users, but in practice it often works incorrectly: the screen suddenly dims in brightly lit rooms or, conversely, blinds your eyes at dusk. If you are tired of the constant surges of backlight and want to return manual control, this article will help you to understand how to completely turn off the autobrightness on Redmi devices, POCO and other brands.

Compounding the problem, newer versions of MIUI (especially 13 and 14) have hidden direct autobrightness settings, leaving users with indirect controls. We tested all current methods on devices from 2022 to 2026 and put them together in a single guide, from standard menu options to hidden commands for power users.

Why is the autobrightness on Xiaomi not working properly?

The MIUI's automatic brightness adjustment algorithm relies on light sensor data and manufacturer-defined parameters, and there are several reasons why the problem arises:

• 🔹 Incorrect sensor calibration – factory settings may not match real lighting conditions.
• 🔹 Aggressive battery saving - in energy saving modes, the system lowers the brightness regardless of external conditions.
• 🔹 The shell conflict is in MIUI 13/14 The brightness algorithm is integrated with Adaptive Brightness, which ignores manual settings.
• 🔹 Software bugs - after software updates, the sensor can "hang" on fixed values.

According to the observations of users, most complaints are received on the models of Redmi Note 11/12, POCO X4/X5 and Xiaomi 12/13. on these devices, the avtobrightness sometimes works with a delay of up to 3-5 seconds, which is annoying when scrolling through social networks or reading.

⚠️ Warning: If after turning off autobrightness, the screen becomes too dim even at maximum settings, check Settings → Display. → Color mode: Vision protection or reading can artificially limit backlighting.

Method 1: Standard shutdown via MIUI settings

On most Xiaomi devices (except for the newest models), autobrightness is turned off via the display menu. MIUI 12–14:

1. Open the settings (cog icon on the desktop).
2. Go to the Display section.
3. Slip on Brightness (or Brightness settings on some firmware).
4. Turn off the Auto-Adjustment slider (may be called Adaptive Brightness or Auto-Brightness).
5. Manually set the desired brightness level with the help of a slider.

If Auto Adjustment is not on the menu, then your device is using a simplified version of MIUI (for example, for the European market), in which case move to the next method.

Check the version of MIUI in Settings → About the phone

Make sure the battery is more than 30% charged.

Close all background applications (especially those with geolocation)

Make a backup of settings through Settings → Additionally. → Backup-->

Method 2: Disconnecting through Developer Mode

On devices with MIUI 13/14 (such as the Xiaomi 13 Pro or Redmi Note 12 Turbo), the standard method may not work, in which case the developer menu, where additional display parameters are hidden, will help.

First, activate the developer mode:

1. Go to Settings. → The phone.
2. Tap 7 times on the MIUI version (you will be notified “You became a developer”).
3. Return to the main Settings menu and open a new section for developers.

Now turn off the autobrightness:

1. In the developer menu, find the item “Disable Auto Brightness” (or “Disable Auto Brightness”).
2. Activate the switch.
3. Restart the device to apply the changes.

⚠️ Attention: On some firmware (POCO F4/F5) This is called Adaptive Brightness Control, and you need to turn it off, not turn it on!

Method 3: Reset brightness settings via ADB

If previous methods have failed, the reset of brightness calibration via ADB (Android Debug Bridge) is suitable for advanced users and requires connecting the smartphone to a PC.

Step-by-step:

1. Download and install Platform Tools on your computer.
2. Enable USB Debugging in the Developer menu (see Method 2).
3. Connect your smartphone to your PC and open the command line (cmd) in the adb folder.
4. Enter the command to reset calibration: adb shell settings put system screen_brightness_mode 0
5. Then set a fixed brightness (for example, 50%): adb shell settings put system screen_brightness 128 (significance 128 correspondently 50% brightness; maximum brightness — 255).

Once you've done the commands, restart the device, and this method resets all the autobrightness values you've saved, including your custom settings.

Method 4: Using Third-Party Applications

If system methods don't work, you can use third-party utilities.

• 📱 Lux Auto Brightness – allows you to manually adjust the brightness curve and disable the standard algorithm MIUI.
• 🔧 Tasker – creates automatic rules for fixed brightness depending on the time of day.
• 🌓 Night Light & Brightness – combines brightness control and blue light filter.

Example of settings in Lux Auto Brightness:

1. Install the app from Google Play.
2. Give permission to change system settings (manually in application settings).
3. From the Lux menu, select Disable system auto-brightness.
4. Set your own brightness curve or set a fixed value.

⚠️ Note: Brightness control applications may conflict with energy saving features MIUI. If after installing the utility, the screen begins to flash, turn off the Adaptive battery in the power settings.

Table: Methods compatible with Xiaomi models

Xiaomi 13 Ultra and Redmi K60 models may need to roll back firmware to an earlier version of MIUI, as in recent updates, the manufacturer has blocked the change in brightness through ADB.

adb shell settings put system minimum_screen_brightness 30

(Default value is 10, maximum is 255).-->

Frequent problems and their solutions

Even after the autobrightness is turned off, users face unexpected difficulties.

• 🔄 Brightness resets after rebooting → Check if the energy saving mode is included in the Settings → Battery.
• 🌡️ The screen will spontaneously dim in some applications → Turn off Adaptive Brightness for Apps in the Display Settings (if any).
• 🔋 After updating MIUI autobrightness is back → Make a reset of settings through Settings → System system → Resetting settings → Reset all settings (without deleting data).

If none of these things worked, it could be a hardware malfunction in the light sensor, and it's easy to check that, so close the sensor (usually next to the front camera) with your finger and see if the screen is responding to the lighting change. If you don't, go to the service center.

💡

On devices with AMOLED-Autobrightness can affect the life of the matrix, fixed brightness at the level of 60-70% reduces the risk of pixel burnout.
