How to remove screen fading on Xiaomi Poco: all ways for MIUI

Your Xiaomi Poco screen goes out too quickly, making it difficult to read articles, watch videos or play? This problem is familiar to many owners of Poco X3, Poco F3, Poco X5 and other smartphones. By default, the MIUI system sets aggressive power saving settings that force the display to turn off after 15-30 seconds of inactivity - even if you actively interact with the content.

In this article, we’ll look at 5 proven ways to turn off screen fading, from standard MIUI settings to hidden features for power users. You’ll learn how to maximize screen timeout to a maximum of 10 minutes, how to bypass restrictions in games and applications, and what to do if settings are reset after an update. All methods are tested on the Poco X4 Pro 5G (MIUI 14), Poco F5 (Android 13) and Poco M5 (MIUI 13).

1. Standard MIUI settings: maximum screen timeout

The easiest way is to change the auto-turn-off time through the settings menu, which works on all Poco models (including the Poco C40, Poco M4 Pro) and does not require super-user rights.

Open the Settings app and follow the path: Screen → Auto-Switch Off. Here you will see options from 15 seconds to 10 minutes. Choose a maximum value of 10 minutes (or 30 minutes if this option is available in your version of MIUI).

• 📱 For Poco. X3/X4: into MIUI 12/13 maximum — 10 minute.
• ⚡ For Poco. F4/F5: into MIUI 14 came up "30 minutes" (only on Android 13+).
• ⚠️ Limitation: In some apps (like YouTube), the screen may go out earlier due to their own settings.

If the option Auto-Switch off screen is not in the menu, check the section Additional in the screen settings or use the search by settings (the magnifying glass icon in the upper right corner).

2. Disable attenuation in developer mode

If the standard 10 minutes are not enough, activate the developer mode and access hidden settings, which will allow you to turn off the attenuation of the screen completely (until manually switching off) or set non-standard timeout values.

How to turn on the developer mode:

1. Go to Settings. → The phone.
2. Find the MIUI version and tap it 7 times in a row.
3. Enter the unlock password if necessary.
4. Return to the main settings menu and a new section for developers will appear.

Now open Settings → For developers and find options:

• Turn off the screen when charging – turn off if the screen goes out during charging.
• Screen waiting time – you can choose Never turn off (on some firmware).
• Do not turn off the screen when charging – useful for reading or watching videos.

💡

If the “Never Turn Off” option is missing, try updating. MIUI before the latest version or use it ADB-Teams (see section 4).

3. Set up exceptions for applications

MIUI allows you to set individual energy saving settings for each application, which is useful if the screen is turned off only in specific programs (for example, in Google Maps or Waze during navigation).

Instructions:

1. Open Settings → Applications → Application Management.
2. Select the app you want (like YouTube or Chrome).
3. Tap Permissions → Autostart and turn on the option.
4. Go back and select the battery. → No restrictions.
5. Activate the screen lock option (if any).

For games (such as Genshin Impact or PUBG Mobile) use Game Turbo:

1. Start the game.
2. Swipe down from top to top to open the notification bar.
3. Slip on the Game Turbo icon (gamepad icon).
4. Turn on the option to not turn off the screen.

4. ADB-commands to completely disable attenuation

For advanced users who are ready to work with Android Debug Bridge (ADB), there is a way to completely disable the auto-turn off screen at the system level, which works even where standard MIUI settings are limited (for example, on the Poco X3 NFC with MIUI 12.5).

Before we start:

• 🔧 Install. ADB Tools on PC.
• 📱 Turn on Debugging. USB developer-setting.
• 🔌 Connect your phone to your computer and confirm your trust in the device.

Open the command line (Windows) or terminal (macOS/Linux) and type:

adb shell settings put global stay_on_while_plugged_in 3

This command will keep the screen on:

• 3 - when connecting to charging and via USB.
• 1 - only when charging from the socket.
• 0 - disables the function.

To set a non-standard attenuation time (e.g. 30 minutes), use:

adb shell settings put system screen_off_timeout 1800000

Where 1800000 is the time in milliseconds (30 minutes).

Install ADB Tools on PC|Enable debugging on USB phone-on|Connect Poco to a computer|Allow debugging in the dialog window|Check the connection with the adb device command-->

💡

ADB-The commands are reset after the phone is reset to the factory settings. To return the settings, repeat the commands after the reset.

5. Special applications for screen control

If system methods don't work, use third-party utilities that allow you to flexibly adjust timeouts, block attenuation in individual applications, and even control brightness automatically.

Top.-3 Proven applications for Xiaomi Poco:

• 🌟 Keep Screen On is a simple utility with a widget for quickly turning on/off the screen lock.
• ⚡ Caffeine – adds a button to the notification panel to temporarily disable attenuation (for example, on the 5/10/30 minute).
• 🛠️ Tasker is for advanced users, and it allows you to create a rule: If you run X, → switch off".

How to set up Keep Screen On:

1. Download the app from Google Play.
2. Open it and grant permission to Overlay over other applications.
3. Add the widget to the main screen or activate the notification.
4. Slip on the widget to block the attenuation (notification will appear).

⚠️ Note: some applications (e.g. Tasker) require permissions for special features. Do not provide access to the Accessibility Services to unknown programs - this may threaten security.

Problems and Solutions: Why the Screen Is Still Dimming

Even after all the settings, the screen can turn off due to hidden MIUI limitations or specific features of specific Poco models.

Problem 1: The screen goes out 1-2 seconds after locking. Solution: This is related to the Up to unlock function. Turn it off in Settings → Screen → Up to unlock.

Problem 2: Settings are reset after rebooting. Solution: This is a bug of some versions MIUI (for example 12.0.3 on Poco X3). Update the firmware or use it ADB-commands for constant application of settings.

Problem 3: In games, the screen is turned off despite the Game Turbo.

• Update the Game Turbo via Google Play.
• Add the game to the battery exclusion list (see Section 3).
• Try another screen locking app (like Caffeine).

Problem 4: On Poco F1 Or older models don't have the option of 10 minutes. ADB-commands (section 4) or install custom firmware (e.g. Pixel Experience) where timeout limits are higher.

💡

If none of the methods work, check the proximity sensor. Sometimes it falsely fires (like in a case) and causes the screen to turn off. Test the sensor with code ##6484## (dial in the dialer).
