How to remove the auto-turn off screen on Xiaomi smartphones: all ways

Xiaomi’s screen that goes out at the wrong time is a familiar problem for many users: You read a long article, watch a video or play a mobile game, and the display suddenly dims, interrupting the process. The reason is the MIUI power saving settings, which by default limit the screen activity time to 30 seconds-2 minutes, but this feature can be turned off or adjusted to suit your needs.

In this article, we’ll cover all the current ways to make sure that Xiaomi’s screen doesn’t go out automatically, from standard settings to hidden features for power users. Instructions are suitable for most models: Redmi Note 10/11/12, POCO X3/X4/X5, Mi 11/12/13 and other devices on MIUI 12-14.

Why is Xiaomi’s screen going out too fast?

Automatically shutting down the display is part of MIUI’s power saving system. By default, the smartphone is set to balance convenience with battery saving. Here are the main reasons why the screen goes out sooner than you’d like:

• 🔋 Power saving mode: one of the profiles (Battery, Supersaving or Ultrasaving) is activated, which forcibly reduces the screen time.
• ⏱️ Screen sleep timer: minimum settings (15–30 seconds).
• 📱 Adaptive brightness: The feature analyzes lighting and may prematurely extinguish the screen in dark conditions.
• 🔄 Updates MIUI: after upgrading the system settings can be reset to factory.
• 🛠️ Sensor malfunctions: If the proximity or illumination sensor is not working correctly, the screen may go out arbitrarily.

On Xiaomi AMOLED-screens (e.g. Mi 11 Ultra or Redmi) K50) The problem may be exacerbated by the Always-On Display feature, which conflicts with sleep timers. MIUI 11) there was also a bug when the screen goes out after 5 seconds regardless of settings - this required manual reset of the system cache.

Method 1: Change the sleep timer in the screen settings

The simplest and most obvious method is to increase the time to automatically turn off the display, which is available in standard MIUI settings and does not require superuser rights.

Instructions:

1. Open the Settings app (cog icon).
2. Go to the Screen section.
3. Select the screen sleep option (or screen timeout in older versions).
4. Set the maximum value of 10 minutes or 30 minutes (not available on all models).
5. Go back and check if the settings are still in place.

If you don’t have a 30 minute menu, it means the manufacturer has limited the maximum time for your model, and you’ll have to use alternative methods (see Methods 3-5).

⚠️ Warning: Some devices still go out after 10 minutes, and this is due to background processes. MIUI, The solution is to turn off adaptive brightness (see next section).

Method 2: Disconnect adaptive brightness and energy saving

Adaptive brightness and energy saving modes can override sleep timer settings, and to keep the screen from going out prematurely, they need to be deactivated.

How to turn it off:

1. Go to Settings → Display.
2. Look for the Adaptive Brightness option and turn off the slider.
3. Go back to the main settings menu and select Battery.
4. Click on Power Saving Mode and install High Performance (or No Limits if available).
5. Turn off the Smart Optimization option (if any).

After this manipulation, check if the screen stays on longer. If the problem persists, move on to the next method.

💡

Some POCO and Redmi models have a hidden option to unlock the screen when notified in Lock and Protect, which can interfere with the normal operation of the sleep timer - turn it off if the screen goes out arbitrarily.

Method 3: Using Developer Mode (for Power Users)

If standard settings don’t work, you can use hidden options in the developer mode, which allows you to increase the screen sleep time to 30 minutes or completely turn off auto-switching (on some firmware).

Step-by-step:

1. Activate Developer Mode: Go to Settings → About Phone. Find the MIUI Version and click on it 7 times in a row. You will be notified of becoming a developer!

For developers

Sleep while connected to charging

Never.

Turn off the screen when inactivity

uncheck the box

On some firmware (MIUI 13+), these options may be hidden.

1. Enable the Developer Mode (as described above).


2. Connect the phone to the PC and use the ADB- command:




adb shell settings put global stay_on_while_plugged_in 3




(where 3 is always on when charging)

⚠️ Warning: Disabling auto-turn off the screen through developer mode can cause the display to overheat and the battery to run faster.Do not use this method constantly – only when necessary (for example, while navigating or streaming).

Method 4: Applications for forced screen switching on

If the system settings don't work, you can use third-party utilities to:

• 📱 Keep the screen on while specific applications are running (YouTube, games, navigators).
• ⏳ Set up individual timers for each case.
• 🔄 Bypassing restrictions MIUI maximum sleep.

How to set up Keep Screen On:

1. Install the app from Google Play.
2. Run it and grant permission to Overlay over other applications.
3. In the main menu, select apps that need to turn off screen sleep (such as YouTube or Google Maps).
4. Activate the switch on.

Method 5: Manually shutting down the proximity sensor (for emergencies)

Sometimes the screen goes out due to a false alarm (e.g. when you hold the phone at an angle or in a case).Switching off the sensor temporarily can solve the problem, but this method is only suitable for one-off situations.

How to turn off the sensor:

1. Enable Developer Mode (see Method 3).
2. Go to Settings. → For developers.
3. Find the option to Disable the proximity sensor (or Show Presses → Approach Sensor).
4. Activate it – now the screen will not go out when objects approach.

Alternative method (without developer mode):

• When you call, type the code ##6484## (sensor test).
• In the menu, look for the Proximity Sensor.
• Cover the sensor with your hand – if the value does not change from 1 to 0, the sensor is faulty.

⚠️ Attention: Constantly turning off the proximity sensor will cause the screen to light up when you make calls from touching your ear!

💡

If the screen goes out because of the proximity sensor, check its operation through the engineering menu. A faulty sensor needs repair - a self-disabling only masks the problem.
