How to set up a screen timer on Xiaomi: The Complete Guide to 2026

Why You Need a Screen Timer and How It Works on Xiaomi

The screen shutdown timer is one of the most useful features in Xiaomi, Redmi and POCO smartphones, which helps save battery life and extend the display life. Many users do not even realize that the standard 30 seconds before locking the screen can be changed to any convenient value - from 15 seconds to 10 minutes. Moreover, new versions of MIUI have expanded settings that allow you to flexibly manage the display activity time depending on use.

It's based on a built-in proximity sensor and energy-saving algorithms, and when you put your phone on the table or stop interacting with it, it monitors the lack of activity and locks the screen at a given interval, which is especially true for owners of devices with a high-speed, low-speed, low-speed device. AMOLED-In a display where each pixel consumes energy even when displaying a black background, setting the timer correctly can increase battery life. 15-25% model-wise.

But there are nuances: some apps (like YouTube or Google Maps) can ignore system settings and keep the screen on longer. In this article, we will discuss not only the basic parameters, but also hidden features that will help you to fully control the behavior of the display on your Xiaomi.

Where to find screen timer settings in MIUI

Depending on the firmware version, the path to settings may vary slightly, but the general logic remains the same. On most Xiaomi devices (including the Redmi Note 12, POCO X5, Mi 13), the timer parameters are hidden in the Screen section.

1. Open the settings (cog icon on the desktop).
2. Go to Always Active Screen and Lock (in older versions of MIUI – Lock and Protect).
3. Select Sleep Mode or Screen Sleep Timer.

If you have a global firmware version installed (e.g. MIUI Global 14), the menu items can be translated as Sleep or Screen timeout. In Chinese, look for characters.

💡

On some models (such as Xiaomi 12T), you can get quick access to the screen timer through the notification panel: swipe down twice and hold the Lock icon.

In this section, you'll see the standard options: 15 seconds, 30 seconds, 1 minute, and so on up to 10 minutes, but that's just the tip of the iceberg, and we'll talk about the hidden possibilities.

How to change the time of automatic screen shutdown

The basic timer setting takes less than a minute.

1. Go to Settings → Always Active Screen and Lock → Sleep mode.
2. Choose the desired interval from the options offered. 15 seconds are recommended for maximum energy saving, but this can be uncomfortable when reading long texts.
3. Confirm the choice – the changes will apply immediately, without rebooting.

If standard values are not enough, you can set custom time through a developer (ADB). For example, on POCO F5, users set a timer of 2 minutes to comfortably watch videos without constantly touching the screen.

Enable Developer Mode (7 times press "Version" MIUI" on the phone")

Connect your phone to your PC and allow debugging over USB

Install ADB-computer-driver

Download the Platform Tools utility from Google

Important: changing system parameters through ADB can cause MIUI to malfunction if you enter incorrect values, and we recommend using this method only for advanced users.

Additional settings: exceptions for applications

One of the things about MIUI is that it can create exceptions for individual applications where the screen won't turn off by timer, and it's useful for:

• 📺 YouTube or Netflix – to ensure that the video is not interrupted while watching;
• 🗺️ Google Maps or Yandex.Navigator – for safety while driving;
• 📊 Reading books on Moon+ Reader or FBReader;
• 🎮 Long-load games (such as Genshin Impact).

To customize the exceptions:

1. Go to Settings → Applications → Permissions → Auto-Switch off the screen.
2. Select the app from the list and activate the Do Not Turn Off screen switch.
3. Some applications (such as Waze) may require additional permission to display over other windows.

On models with MIUI 14+ (such as Xiaomi 13 Ultra), a feature called Smart Shutdown, which analyzes your habits, for example, if you regularly watch videos in the evening, the system can automatically increase the screen timer at this time.

Screen timer problems and their solutions

Sometimes users find that the screen turns off too quickly or, conversely, does not lock at all.

⚠️ Note: If after the update MIUI The screen timer started to work incorrectly, try resetting the settings only for the Settings application (Settings) → Annexes → Application management → Settings → Reset.It often helps without completely resetting your phone.

On devices with MIUI 13 and below, sometimes a rollback to the factory timer settings helps through the command:

adb shell settings put system screen_off_timeout 30000

Where 30,000 is time in milliseconds (30 seconds).

15 seconds.

Hidden functions: adaptive timer and gestures

Few people know, but MIUI has hidden screen controls that are not advertised in standard settings.

• 👁️ Adaptive timer: The system analyzes your behavior and automatically adjusts the time of shutdown. → Special facilities → Adaptive screen sleep time.
• 🤏 "Raise to wake up" gesture - if you turn on this option, the phone will unlock when you lift, but the screen will remain active longer when you hold it in your hand. → Always active screen and lock → Raise to wake up.
• 🔄 Double tap to wake up – allows you to quickly turn on the screen without a power button, which is convenient when using a timer of 15 seconds.

On flagship models (Xiaomi 14, Mix Fold 3), the Smart Screen feature is available, which uses the front camera to track your gaze. If you look at the display, the shutdown timer is reset. Activated in Settings → Screen → Smart screen.

⚠️ Attention: Camera and sensor-based features significantly increase battery consumption. 4500 mAh (e.g. Xiaomi) 12 Lite can reduce the time spent on 10-15%.

For owners. POCO s POCO Launcher is available unique option Game Turbo, which automatically turns off the screen timer in games and returns the standard settings after exit. → Special functions → Game mode.

Energy Saving and Screen Timer: How to Find Balance

The optimal time to turn off the screen depends on the use case, and we analyzed data from the 4PDA and XDA Developers forums and made recommendations:

Maximum energy savings on devices with AMOLED-Xiaomi 13 Pro, Redmi K60) Combine a short timer (15 seconds) with a dark theme and adaptive brightness. DXOMARK, This reduces the energy consumption of the screen by up to 40%.

💡

On devices with a battery of less than 4000 mAh (for example, Xiaomi 12 Lite), the optimal timer is 30 seconds. On flagships with 5000 mAh and above, you can increase to 1 minute without significantly affecting autonomy.

If you use wireless charging, keep in mind that constantly turning on the screen when charged can cause overheating, in which case we recommend setting a timer for 1 minute even when watching videos.
