The smart mode on Xiaomi smartphones is a set of features that automatically optimizes the operation of the device: from controlling the brightness of the screen to allocating the resources of the processor. For some users, it is convenient, for others โ an annoying โartificial intelligenceโ that interferes with manual settings. If your Redmi, POCO or Mi has spontaneously adjusted brightness, block background processes or limit performance, itโs time to figure out how to turn it off.
In this article, weโll look at all the options we can get from partially disabling individual functions to completely resetting smart algorithms. Itโs important to understand that different versions of MIUI (12, 13, 14, 15) may have different paths to settings, and some options are hidden within the developer. Weโve taken all the nuances and prepared up-to-date instructions for 2026 โ including bypassing the restrictions on new HyperOS models.
What is Xiaomiโs Smart Mode and Why Disable It
Smart mode (or AI-Optimization is Xiaomiโs proprietary technology that analyzes your habits and automatically adjusts your habits:
- ๐ฆ Adaptive brightness โ screens under ambient light (often working incorrectly)
- ๐ Battery management โ limiting background processes to save charge
- โก Productivity - trottling CPU/GPU heat-up
- ๐ถ Network Connections โ Automatic Switch between Wi-Fi and Mobile Data
- ๐ต Sound profiles โ change in volume depending on the time of day
On paper, this sounds good, but in practice, users face problems:
- ๐ Spontaneous decrease in brightness even with sufficient lighting
- ๐ข Slowing down in games or heavy applications
- ๐ซ Closing background applications (such as music or instant messengers)
- ๐ Unstable Internet connection due to auto-switching
Turning off the smart mode will give you full control of the device, but note that this can increase battery consumption and increase heating under intense loads. On the new flagships (Xiaomi 14, Redmi K70), some of the functions are integrated into HyperOS, and turning them off requires additional manipulation.
Method 1: Turning off adaptive brightness (the simplest method)
If youโre only annoyed by automatic screen brightness control, you just need to turn it off separately, without any system settings, and this works on all Xiaomi devices, regardless of the MIUI or HyperOS version.
Instructions:
- Open Settings (the gear icon on the main screen).
- Go to the Screen section.
- Find the option Adaptive Brightness (or Automatic Brightness Adjustment).
- Move the slider to the off position.
- For reliability, also turn off Dark Reading and Night Mode if they are active.
After that, the brightness of the screen will be fixed. To change it, use the slider in the notification curtain or in the same screen settings.

If the adaptive brightness is too dim after the switch off, check the Contrast and Color Temperature settings in the same section of the Screen, and sometimes resetting these parameters to factory values helps return a normal picture.
Method 2: Deactivate Smart Optimization in Battery Settings
One of the most intrusive features of the smart mode is battery optimization, which aggressively closes the background processes and limits performance. You can turn it off via the power menu, but the new versions of MIUI 14/15 and HyperOS have changed the way.
For MIUI 12/13:
- Go to Settings โ Battery and Performance.
- Select Battery Settings.
- Turn off the options: ๐ Smart Battery Optimization โก Optimizing application launches ๐ Automatic power management
For MIUI 14/15 and HyperOS:
- Go to Settings. โ Battery.
- Slip on the three dots in the top right corner and select Battery Settings.
- Turn it off: ๐ค AI-battery optimization ๐ Adaptive nutrition management
Performance mode
High productivity
Attention! Some models (POCO F5, Redmi Note 12) may display a โhigher energy consumptionโ notification after the battery optimization is turned off, and can be ignored or disabled in the notification settings.

Method 3: Completely disabling the smart mode through hidden settings (for advanced)
If previous methods have not worked, then the smart mode is fixed at the system level, in which case you will have to use the developer mode or special ADB commands.
Step 1: Activate the Developer Mode
- Open the Settings. โ The phone.
- Tap 7 times on the MIUI version (or HyperOS build number).
- Enter a pattern lock or password if required.
- Return to the main settings menu and a new section for developers will appear.
Step 2: Turn off optimization via ADB (computer required)
- Connect your phone to your PC via USB and enable USB Debugging in the developer settings.
- Download Googleโs Platform Tools and unpack.
- Open the command line in the adb.exe folder and type:
adb shell settings put global miui_optimization_disable 1
adb shell settings put global hidden_api_policy 1These commands will disable most system optimizations, including smart mode.
Step 3: Alternative without ADB (for MIUI 14+)
If ADB is not available, try manually disabling options in Settings โ Special Features โ Smart Features and reset Adaptive Brightness settings through Reset screen settings in the same section.

Method 4: Resetting the smart mode settings to factory
If you've tried different methods and the system is still "smarter" than it should be, it's going to help to reset specific settings. It's not a complete reset of the phone, but only a return to factory settings. AI-optimization.
Instructions:
- Open Settings โ System and device โ More
- Select Settings Reset.
- Tap Reset screen settings (this will return brightness and color profiles to factory ones).
- Then select Reset Battery Settings (this will cancel all power optimizations).
- Confirm the action and restart the device.
Examples of MIUI Hidden Settings:
- Install and open the application.
- Go to the Battery section.
- Find options marked AI or Smart and turn them off.
- In the Display section, reset the adaptive brightness settings.
Important: Using third-party utilities can disrupt system stability. On HyperOS devices (such as Xiaomi 14), some features can be blocked at the kernel level.

App side is effective but risky. Before using them, back up your data via Settings โ System and Device โ Backup.
Frequent problems after switching off the smart mode and their solutions
Shutdown AI-Optimizations don't always go smoothly. Here are the typical problems and ways to fix them:
1. Increased battery consumption
- ๐ Check which apps consume the most charge in Settings โ Battery โ Battery utilization.
- ๐ต Turn off background activity for unnecessary apps manually.
- ๐ Enable Power Saving Mode in Battery Settings (but not Ultra Mode").
2.The screen has become too bright/dull
- โ๏ธ Manually calibrate the brightness in Settings โ Screen. โ Brightness.
- ๐จ Reset the color settings: Settings โ Screen. โ Color mode โ Standard.
- ๐ Check if reading or vision protection is enabled.
3 Applications have become slower to operate
- โก Set the performance mode to High in the battery settings.
- ๐๏ธ Clear the cache through Settings โ Warehouse โ Cleanup.
- ๐ Restart the device โ sometimes it helps to wake up the processor.
4. Proprietary functions have stopped working (e.g. Always-On Display)
On some models (Xiaomi 13 Pro, POCO F4 GT), disabling the smart mode can block branded features to return them:
- Turn on Adaptive Brightness (even if you donโt use it).
- In the developer settings, turn on debugging by USB Adb shell settings put global settings miui_optimization 1
- Reboot the phone.
