Why Xiaomi’s screen goes down quickly and how to fix it: The Complete Guide

Why does Xiaomi’s screen go out early?

Have you noticed that your Xiaomi, Redmi or POCO display turns off after 10-15 seconds of inactivity, even though it used to last longer? This problem occurs to many users after updating MIUI or resetting, the reason usually lies in the automatic screen timeout - a feature that turns off the backlight to save battery power.

The standard MIUI wait time is 30 seconds, but it can get lost due to:

• 🔄 Firmware updates - new versions MIUI Sometimes they reset user settings.
• 🔋 Energy saving mode – aggressive food schemes reduce timeout
• 🛠️ Third-party applications – some programs (such as memory cleaners) force the screen to be extinguished
• 📱 Hardware features - on budget models (Redmi) 9A, POCO C31) default time

Fortunately, you can fix this in 2 minutes through standard settings, and then we'll go through all the ways, from basic to advanced.

Method 1: Set up a timeout through “Settings”

The easiest method is to change the auto-switch time in the system menu, which is available on all Xiaomi smartphones regardless of the MIUI version (even on the old Redmi 4X or Mi A1).

Instructions:

1. Open the Settings app (cog icon)
2. Go to the Screen section (or Display on some firmware)
3. Select the Dream item after (or screen timeout)
4. Set the desired time: from 15 seconds to 30 minutes (optimum 1-2 minutes)
5. Confirm the choice

Battery charge > 15%|Power saving mode is disabled"|No active VPN-programme|The smartphone doesn't overheat.-->

Important: On some models (Xiaomi 12, Redmi Note 11), this item may be hidden in Settings → Battery and Performance → Battery settings → Sleep after. If you do not find it, use the search by settings (the magnifying glass icon at the top).

⚠️ Note: Setting the time more 5 This increases the battery consumption significantly. POCO F3 others AMOLED-Smartphones can reduce autonomy 10-15%.

Method 2: Disconnecting energy-saving modes

Aggressive power schemes are a common cause of premature screen shutdown. MIUI has several levels of energy saving, each of which affects timeout:

To get back to normal timeout:

1. Go to Settings → Battery and Performance
2. Select Power Mode
3. Set high performance or balanced
4. Reboot your phone (required!)

💡

If the screen goes off quickly after the power saving is turned off, check the settings of specific applications. Some programs (for example, Facebook or Telegram) have their own sleep parameters, which can conflict with the system.

Method 3: Setup through the developer (for experienced)

If standard methods don't work, you can manually change your sleep patterns through the developer menu, which is suitable for advanced users and requires caution.

Algorithm of action:

1. Activate Developer Mode: Go to Settings → About Phone 7 times click on the MIUI Version (you will be notified “You became a developer”)

Additional → For Developers

Do not turn off the screen during charging

⚠️ Warning: Sloppy changes to the developer menu can lead to sensor failures or autobrightness.On Xiaomi 13 Pro and newer models, the wrong settings are in place ADB It can block access to certain camera functions.

Method 4: Verification of Third-Party Applications

Some programs force the screen to be turned off to "optimize" the work, most often the culprits:

• 🧹 Memory Cleaners (Clean Master, CCleaner)
• 🔒 Antiviruses (Avast, 360 Security)
• 📱 Launchers (Nova Launcher, POCO Launcher)
• 🔋 Battery applications (AccuBattery, GSam Battery Monitor)

How to find the culprit:

1. Launch your phone in Safe Mode (press the power button → Safe Mode)
2. Check if the screen is going off at the same speed.
3. If the problem is gone, delete the programs one by one, testing after each removal.
4. For accurate diagnosis, use Settings → Apps → Permissions → Autorun and disable suspicious programs

Example: On the Redmi Note 10 Pro, users often face a conflict between MIUI Optimization and Greenify, the solution being to disable auto-optimization in the battery settings for these applications.

💡

If the screen goes out only in a particular application (for example, in YouTube or Chrome), the problem lies in the settings of this software. Check the settings of "Data Saving" or "Background" in the application itself.

Method 5: Reset screen settings (extreme case)

If none of these methods work, you just have to reset the display to the factory settings, and it won't delete your data, but it will return all of the screen settings to default.

Step-by-step:

1. Open Settings → System and device → Additional → Resetting
2. Select Reset Screen Settings (not to be confused with a full reset!)
3. Confirm the action with a password / pattern lock
4. After rebooting, reset brightness, timeout and color temperature

⚠️ Note: On the Xiaomi Mi 11 and newer, resetting the screen settings also resets the Always-On Display calibration. After the procedure, you will have to reconfigure the display of time and notifications on the switched-off screen.

If the reset didn't work, it could be a hardware problem. On the POCO X3 Pro and Redmi K40, this display behavior sometimes causes:

• 🔌 Faulty display plume (after falling or repairing)
• 🔋 Bloated battery (gives false signals to the power controller)
• 📱 Damaged proximity sensor (erroneously triggered as a lock)

Additional advice for specific models

Some Xiaomi smartphones have unique screen controls:

For owners of Xiaomi Pad 5/6: on tablets, the screen sleep time is set separately for Read and Video mode. Check both settings in Settings → Screen → Usage Modes.
