Xiaomiβs smartphone screen goes out too quickly or stays on longer than it should? This problem is familiar to many users of MIUI-based devices. By default, the system sets standard time slots that are not always convenient: for example, when reading a book or watching a photo, the screen can turn off after 15-30 seconds, forcing you to constantly touch the display. On the other hand, too long screen time reduces the autonomy of the device.
In this article, weβll look at all the ways you can change your screen fade time on Xiaomi, Redmi and POCO smartphones, from basic menu settings to hidden features for power users. Youβll learn how to set up automatic display shutdown for your tasks, save battery life and avoid accidental touches. Instructions are relevant for MIUI 12, 13, 14 and earlier, as well as for most models, including Xiaomi 13/14, Redmi Note 12/11 and POCO F5/X5.
Why Xiaomiβs screen goes out quickly: the main reasons
Before you change the settings, it is important to understand what affects the display time. In Xiaomi devices, several factors are responsible for this:
- π Power saving mode: When activated, Ultra-Economic or Battery mode is activated, the system automatically reduces the screen time to fade to 15-30 seconds.
- π± Version. MIUI. In new firmware (e.g, MIUI 14) power management algorithms have become more aggressive, which may result in a faster shutdown of the display.
- π Adaptive backlighting: Adaptive dimming in some models (Xiaomi) 12T, Redmi K50) analyzes lighting and can force the screen to be extinguished.
- π οΈ Sensor malfunctions: If the proximity or illumination sensor is not working properly, the screen can be turned off arbitrarily.
It is also worth considering that on some models (for example, the POCO F4 GT or Black Shark 5), the screen attenuation time in games is adjusted separately through the settings of the Game Turbo game space. If you notice that the screen goes out only in certain applications, the problem may lie in their individual settings.
β οΈ Warning: If the screen still goes out after 5-10 seconds after the change, check the proximity sensor. Cover the top of the phone with your hand during the call, the screen should go out. If this does not happen, the sensor may be contaminated or damaged.
Method 1: Change the attenuation time through standard MIUI settings
The easiest method is to use the built-in system options. The instructions are suitable for all devices on MIUI 12-14, including Xiaomi 13 Lite, Redmi Note 11 Pro and POCO X4 Pro:
- Open the Settings app (the gear icon on the home screen).
- Go to the Display section.
- Select the item Sleep after (in some versions β Screen Attenuation or screen timeout).
- Set the desired interval: from 15 seconds to 10 minutes (on some models, 30 minutes are available).
- Confirm your choice by returning to the previous screen.
If your menu doesnβt have a Sleep After item, try an alternative path:
Settings β Battery and performance β Battery settings β Sleep afterMake sure your phone is over 20% charged.
Turn off the power saving mode

On devices with AMOLED-screens (e.g. Xiaomi) 12S Ultra or Redmi K60 Pro) when choosing a long fade time (5-10 minutes), a warning may appear about increased battery consumption, due to the features of organic displays that consume energy even on a black screen due to the operation of the pixel backlight.
Method 2: Configure through Developer Mode (for power users)
If standard options donβt work (e.g., set a fade time of more than 10 minutes), you can use the developer mode, which works on all Xiaomi devices, but you need to be careful:
- Activate Developer Mode: Go to Settings β About Phone. Find the MIUI Version and tap it 7 times in a row. You will be notified of becoming a developer!

β οΈ Warning: The option can never cause the screen to overheat and quickly discharge the battery, especially on devices with a battery. AMOLED-Use it only when connecting to a charger or for temporary tasks (e.g. presentations).
On some models (POCO F3 GT, Black Shark 4) the developer menu also offers the option to Stay Active while charging. If you turn it on, the screen will not go out while the device is connected to the network, which is convenient for using the phone as a media player or navigator in the car.

Method 3: Using applications to control the screen
If the built-in settings don't allow you to set the right time to fade, you can use third-party utilities.
- π± Keep Screen On: Keep Screen On allows you to keep the screen on while the app is in the background.
- β±οΈ Screen Timeout Settings β Expands the standard timeout options to 30 minutes.
- π Tasker (for advanced users) β automates screen control according to schedule or events (for example, turn off the display only at night).
Example of settings in Keep Screen On:
- Download the app from Google Play.
- Launch it and grant permission to Overlay over other applications (in the security settings).
- Select applications that need to turn off screen fade (such as Chrome or WPS Office).
- Activate the function Keep the screen on.

Method 4: Configure screen attenuation via ADB (for advanced)
If none of the above methods helped, you can change the attenuation time through ADB-This will require connecting the phone to a computer and basic command line knowledge:
- Install. ADB-PC drivers.
- Enable USB debugging on your phone: Settings β Additional β For developers β Debugging over USB
- Connect your phone to your computer and open the command line (or Terminal on Mac/Linux).
- Enter the command to check the connection: Adb devices should appear the name of your device.
- Set a new attenuation time (in milliseconds). 5 minute (300 000 MS): adb shell settings put system screen_off_timeout 300000
To return the standard settings, use:
adb shell settings delete system screen_off_timeoutβ οΈ Attention: Misuse of the right ADB It can cause system failures, and don't change other settings unless you're sure they're there. MIUI settings may reset.
For devices with MIUI 13/14 and unlocked bootloader, you can use more flexible commands via Magisk or TWRP, but this requires root rights and is not recommended for beginners.

Depending on the series and firmware version, the process of changing the attenuation time may differ.

On POCO and Black Shark, check the Game Turbo settings before changing the damping time β they can override system settings.
What to do if the settings are not saved?
Sometimes, after the fading time changes, the screen continues to go out as it was.

|---|---|---|
| Settings are reset after rebooting | Conflict with the battery optimizer | Add the Settings app to optimisation exclusions |
| The screen goes out in 5 seconds. | Pocket mode activated | Turn it off in Settings β Display β Pocket mode |
| No time to choose > 10 minutes | Firmware restriction | Use ADB or Developer Mode |
