Standard MIUI settings: maximum latency

The easiest way to increase the time to turn off the screen is to use the built-in MIUI options. Unfortunately, the manufacturer limits the maximum value (usually 10 minutes or 30 minutes), but this is enough for most tasks.

To change the timer:

1. Open Settings → Screen (or Display in new versions).
2. Select the screen sleep option (can be called screen timeout or auto-switch off).

3. Return to the main settings menu and open a new section for developers (may be in Additional).

Now look for the option to turn off the screen when inactivity (or Sleep timeout in English firmware). Here you can select values up to 3600 seconds (1 hour). On some firmware (for example, HyperOS for Xiaomi 14), this item is called screen time to sleep and supports Never.

Activate Developer Mode (7 taps according to MIUI)

Check the battery power (minimum 30%)

Disable battery optimization for system applications-->

⚠️ Attention: On devices with AMOLED-screens (e.g. Xiaomi 13 Ultra or Redmi) K60 Pro) the display is constantly operating at maximum brightness can cause pixels to burn out. Use this method only when connected to charging.

3. ADB-commands: complete timeout shutdown (no root)

If you need to permanently remove the auto-shutdown screen without time limits, you can use the ADB-This method doesn't require a superuser's rights, but it requires a computer and enabled debugging. USB.

This command will make the screen stay on only when connected to charging. To turn off the timeout completely (even on the battery), use:

adb shell settings put system screen_off_timeout 2147483647

The value of 2147483647 (maximum for a 32-bit system) is equivalent to ~68 years — essentially, it's Never. To return the standard settings, type:

adb shell settings delete system screen_off_timeout
