Xiaomi screen goes out in 5-10 seconds? fix the problem in 5 minutes

You picked up your Xiaomi Redmi Note 12 or POCO X5 Pro to read the message, and the screen goes out just a few seconds after the last touch. You have to constantly unlock the phone, which is annoying and wastes battery life. Sounds familiar? This problem occurs on most Xiaomi devices, regardless of the model or version of MIUI. The reason for this can be both incorrect system settings and software failures.

In this article, we’ll look at all the possible reasons why your smartphone’s screen goes out too quickly, from basic latency settings to hidden power saving features. You’ll learn how to return a comfortable screen life without constantly unlocking, even if standard methods don’t help. And for owners of older models (such as the Redmi 4X or Mi A2), we’ve prepared separate recommendations tailored to the specifics of their firmware.

Before you start settings, check if the screen behavior is associated with mechanical damage. If the phone falls or gets wet, the problem may lie in the proximity sensor or the display plume, in which case repairs will be required. In all other situations, our instructions will help to return the normal screen time.

1. Check basic waiting time settings

The most obvious reason for the quick shutdown is the wrong latency settings, and even if you didn't consciously change those settings, they could reset after updating MIUI or installing third-party applications to optimize the battery.

To check the current settings:

1. Open the Settings → Display.
2. Select Sleep Mode (or Screen Wait Time in older versions of MIUI).
3. Set the value from 30 seconds to 10 minutes, depending on your preferences.

Note: on some models (for example, Xiaomi 13 Ultra or POCO F5) this option may be hidden in the submenu Additional screen settings. If you do not find the item Sleep mode, search by settings (the icon of the magnifier in the upper right corner).

2. Disconnection of the energy saving mode

Xiaomi’s energy-saving features aggressively optimize the system, including forcefully reducing screen activity time, both in standard Battery mode and in advanced options like Super Power Saving or Ultra Mode (available on MIUI 14+ models).

To check and disable these modes:

• 🔋 Go to Settings. → Battery and productivity.
• 📱 Select Battery Mode and set Balanced or Performance.
• ⚡ Turn off the Super Energy Saving Slider (if it is active).
• 🔄 In Battery Optimization, find the applications that have Background Limitation set and remove the restrictions for frequently used programs.

Important! On some firmware (e.g. MIUI Global for the European market), the power saving mode can be activated automatically at a low charge level (below 15%). To avoid this, set a 10% threshold in the battery settings or turn off automatic power at all.

💡

If the power-saving device still goes out quickly after the power-saving shutdown, try restarting the phone. Some settings apply only after the reboot.

3. Resetting the proximity sensor settings

The proximity sensor is responsible for turning off the screen when you hold the device to your ear when you make phone calls. If it doesn't work properly, the phone can "think" you're talking and turn off the screen even when you're in normal mode. AMOLED-screens (e.g. Xiaomi) 12T or Redmi K50), where the sensor is integrated into the display.

To reset the sensor calibration:

1. In the phone app, type the code: ##6484###
2. In the menu, select Test Proximity Sensor.
3. Cover the sensor (usually located at the top of the screen) with your finger - the screen should go out, and with the finger removed - again light up.
4. If the reaction is incorrect, press Calibrate or Reset.

If the sensor doesn't respond at all, the problem could be hardware.

• 🛠️ Check if there is any dirt or protective film above the sensor (it can block its operation).
• 📲 Try calibrating the sensor through the engineering menu (code ##4636##, but be careful - not all items there are safe!).

4. Verification of applications that control the screen

Some apps may force the screen to be turned off for battery saving or other reasons, most often the fault being:

• 🔄 Battery Optimizers (e.g. Greenify, AccuBattery).
• 📱 Launchers (for example, Nova Launcher or POCO Launcher) if they are in conflict with MIUI.
• 🎮 Gaming utilities (such as Game Turbo in Xiaomi) that may limit background activity.
• 🛡️ Antiviruses (e.g. Avast or 360 Security) that block suspicious activity.

To find the culprit:

1. Launch your phone in Safe Mode (press the power button → Disable power → hold off Turn off until you get a suggestion to go to Safe Mode).
2. If the screen is working normally in safe mode, the problem is in one of the installed applications.
3. Remove suspicious programs, starting with the battery optimizers.

Critical information: On some models (e.g. Redmi Note 10 Pro), the system application Security may cause a conflict. It cannot be removed, but you can reset settings: Settings → Applications → Application Management → Security → Storage → Clear data.

5. Update MIUI and reset settings

If the problem has occurred after a system update, a firmware bug may be to blame. Xiaomi regularly releases patches for such bugs, so check for updates first:

1. Go to Settings → About the phone → System update.
2. Click Check Updates and install the latest version of MIUI.

If the update is not available or it didn’t help, try resetting your system settings without losing data:

• 📱 Go to Settings. → Additionally. → Resetting settings.
• 🔄 Select Reset Network, Display and Sound Settings (not to be confused with a full reset!).
• ⚠️ Confirm the action – the phone will restart, but your files and apps will stay in place.

For owners of devices with MIUI 13 and later, there is another way to reset through the MIUI Lab:

1. Activate Developer Mode (7 times click on the MIUI version in About Phone).
2. Return to Additional Settings → MIUI Lab → Resetting.
3. Select Reset Display Settings.

6.Verification for viruses and malware

Malware can change system settings, including screen time, for example, some Trojans force the power saving mode to hide their activity, to rule out this cause:

First, scan your phone with the built-in antivirus:

1. Open the Security app (the shield icon).
2. Select the scanner. → Deep inspection.
3. Wait until the scan is finished and remove the threats found.

If the built-in scanner found nothing, use third-party antiviruses:

Once the viruses are removed, restart your phone and check the screen. If the problem persists but the antivirus finds the threat, perform a full reset (with loss of data) as the malware may have damaged system files.

💡

Viruses are often disguised as system applications (such as Android System or Google Services).

7. Hardware problems: when you need help from the service

If none of the software methods worked, the problem could be in the hardware of the phone, and here are some signs that you need to repair it:

• 🔧 The screen goes off instantly (less than 1 second) after locking.
• 📱 Artifacts (strips, flickering) appear on the display before switching off.
• 🔋 The phone is discharged too quickly (for example, 20% per hour in standby mode).
• 🛠️ The problem appeared after a fall, moisture hit or a screen replacement.

The most common hardware reasons:

⚠️ Warning: If you notice that the screen only goes out when you connect to charging, immediately disconnect the phone from the network! this may indicate a short circuit in the power controller, which is fraught with fire.

For diagnosis, contact the Xiaomi service center or a checked repair center. The average cost of diagnosis is 300-500 rubles. We do not recommend disassembling the phone yourself, especially if it is warranty (this cancels it).

8. Alternative solutions for experienced users

If standard methods don't work and you can't use the service, you can try more radical methods, which are suitable for those who are willing to take risks or have experience with ADB and custom firmware.

Method 1: Change the waiting time of ADB

This method allows you to manually set the screen time, bypassing the limitations of MIUI:

1. Install. ADB-PC drivers.
2. Connect your phone to your computer and enable USB Debugging (Settings → About Phone → MIUI Version → 7 times Press → Additional Settings → For Developers → USB Debugging).
3. Open the command line (Windows) or terminal (macOS/Linux) and type:

adb shell settings put global screen_off_timeout 300000

Where 300000 — millisecond (300 000 = 5 For a minute. 1 minutes to use 60000.

Method 2: Installation of a custom core

On some firmware (e.g. MIUI EU), screen latency is limited to the kernel level, so you can install a custom core like FrancoKernel or ElementalX, where it's unlocked. You can look for instructions on the XDA Developers or 4PDA forums for your model.

⚠️ Attention: Use ADB And custom firmware can lead to a device blink (completely inoperable) or loss of warranty. TWRP Or Mi Flash Tool.

💡

If you're not sure about your skills, you should ask for help on topic forums or someone you know about firmware. Mistakes with ADB can make your phone unusable.
