How to remove the auto-shutdown screen on Xiaomi Redmi: all working methods

Why the screen goes off too fast – and how to fix it

You read an important message, watch a video, or play a game on Xiaomi Redmi, but the screen suddenly goes out after 10 to 30 seconds? It's a standard MIUI power-saving feature that turns off the display when you're inactive. However, sometimes it works too aggressively - for example, while reading books, watching presentations, or using your phone as a navigator.

The reasons for early screen shutdowns can range from basic latency settings to proximity sensor errors or battery optimization. In this article, we’ll look at all the possible ways to keep the Redmi screen on longer, from standard settings to hidden features for power users. Methods tested on Redmi Note 12 Pro+, Redmi 11 Prime, Redmi 10C and others with MIUI 13-15.

Important: Some solutions require developer rights or PC connectivity, and if you're a beginner, start with the first three, which are the easiest and most secure.

Method 1: Increase screen waiting time in standard settings

The most obvious and quickest method is to change the display auto-off timeout, which is set to 30 seconds by default in MIUI, but can be increased to 10 minutes.

How to do this:

• 📱 Open the Settings. → Screen.
• ⏳ Select Sleep Mode (or Screen Timeout in new versions) MIUI).
• 🔢 Set the desired time: from 15 seconds to 10 minutes.
• ✅ Confirm the changes.

Note that on some Redmi models (e.g. Redmi A1+), the maximum value may be limited to 5 minutes, and this option is reset after the MIUI update.

Method 2: Disable battery optimization for active applications

MIUI aggressively optimizes the background of applications to save power, sometimes causing the screen to go out even when you’re using it, such as reading books on Google Play or browsing maps on Yandex.Navigator.

To fix this:

1. Go to Settings → Applications → Application Management.
2. Select the app where the screen goes out (like Chrome or Waze).
3. Press Battery Optimization.
4. Choose No Limits.

For system applications (e.g. Camera or Gallery), the path may be different: Settings → Apps → Permissions → Autorun → enable autorun for the desired application.

💡

If the screen goes out during a YouTube video, open the app settings and turn off the option “Video Optimization” – it forcibly reduces the brightness and can cause false alarms of sensors.

Method 3: Use Do Not Disturb mode for constant lighting

A little-known feature of MIUI is Do Not Disturb mode with exceptions. If you turn it on with the right settings, the screen will not go out when you are actively using it.

Instructions:

• 🔕 Go to Settings. → Sound and vibration → Don't disturb.
• 🔄 Activate the mode and select Configurable.
• 📱 In the Exceptions section, add apps where the screen must remain on (e.g. Google Maps or Telegram).
• 🔄 Enable the option to Allow screen lighting (if any).

This method is particularly useful for navigation applications where it is important to see the screen constantly, but it can increase battery consumption by 10-15%.

Method 4: Activate Developer Mode and Disable Timeout

For advanced users, there's a way to completely disable the auto-turn off of the screen through the developer menu, which comes in handy if you're using the phone as a camera monitor, for streaming or testing apps.

Steps:

1. Activate Developer Mode: Settings → About Phone → MIUI version (click 7 times) will be notified “You became a developer”.
2. Back to Settings → Additionally. → For developers.
3. Find the Sleep mode option when connecting to charging and select Never.
4. To completely turn off the timeout, find the screen wait time and set the maximum value.

⚠️ Note: this method significantly increases battery consumption and is not recommended to be used continuously on phones with a small battery (e.g. Redmi). 9A or Redmi 10A).

Activate Developer Mode (7 taps according to MIUI)

Connect your phone to charge (recommended)

Method 5: Use ADB-commands to force timeout

If the standard settings do not help, you can apply ADB-This will allow you to change system parameters that are not available through the interface. MIUI.

Step-by-step:

1. Download Platform Tools from the Android site and unpack the archive.
2. Enable USB Debugging in the Developer menu (see Method 4).
3. Connect Redmi to your PC and type in the command line: adb shell settings put global stay_on_while_plugged_in 3 This command will make the screen stay on when connected to charging.
4. To cancel, enter adb shell settings put global stay_on_while_plugged_in 0

⚠️ Attention: misuse ADB This can cause phone malfunctions. Before experimenting, back up your data through Settings. → Additionally. → Backup and reset.

Method 6: Third-party applications for screen control

If system methods don't work, you can use Google Play apps that allow you to flexibly adjust timeouts, ignore sensors, and even create rules for individual applications.

Top.-3 tested applications:

• 🔄 Keep Screen On is a simple switchboard to turn off auto-turnouts.
• ⚙️ Caffeine – allows you to set timers and exceptions for applications.
• 📱 Screen Alive – Supports gestures and automation (e.g., not extinguishing the screen when tilting the phone).

Example of Keep Screen On settings:

1. Install the application and open it.
2. Turn on the Keep Screen option on.
3. Add the application to Battery Optimization Exceptions (see Method 2).
4. Run your target app (like Google Maps) and the screen won’t go out.

The downside of third-party apps is that they consume an extra battery and may conflict with MIUI. Before installing, check the reviews for your Redmi model.

💡

Third-party applications are a temporary solution. Once the MIUI is updated, they may stop working. Use ADB or the developer settings for permanent effect.

Frequent problems and their solutions

Even after all the methods are applied, the screen can continue to go out. Let's consider the typical causes and ways to eliminate them:

If none of the methods worked, the problem may be a hardware failure — for example, a malfunction of the screen plume or power controller. In this case, contact the Xiaomi service center. For diagnostics, you can use the equipment test: Settings → About the phone → All specs → Test.
