GPS-navigator or during long videos – constantly turning on the screen annoys and distracts.

In this article, we’ll look at all possible ways to disable automatic screen extinction on Xiaomi devices, including hidden developer settings, third-party apps, and workarounds for different versions. MIUI (You will learn how to increase the time to turn off the display to a maximum or remove the restriction altogether, as well as what it threatens the battery and how to minimize the risks, POCO X5, Xiaomi 13 and others.

Why Xiaomi’s screen is going out: technical reasons

Automatically turning off the screen is not a whim of the manufacturer, but part of MIUI’s energy-saving strategy. Even in standby mode, the display consumes up to 30-50% of the battery, so the system limits its operation.

• 🔋 Battery savings: According to Xiaomi, increasing screen timeout with 30 second 10 Reduces the time of autonomous operation by 15-25%.
• 🛡️ Protection against burnout OLED: On devices with AMOLED-With screens (for example, Xiaomi 13 Pro) constant backlight accelerates the degradation of the matrix.
• 🤖 Politics MIUI: In the latest versions of the firmware (starting with the MIUI 14) maximum timeout is artificially limited to 30 minutes.
• 🔒 Security: Quickly turning off the screen reduces the risk of unauthorized access if the phone is left unattended.

Interestingly, on some models (e.g., POCO F5), the time to the screen’s extinction depends on the performance mode. In Battery mode, the timeout is shorter than in Performance. This is also influenced by adaptive brightness, which, when activated, can reduce the time before the display is turned off in low light conditions.

Method 1: Standard MIUI settings (without root)

The easiest and safest method is to use the built-in options, which is suitable for all versions of MIUI (12 to 15) and does not require superuser rights.

1. Open the Settings app (the gear icon on the home screen).
2. Go to the Display section (or the Screen on some models).
3. Find Sleep Mode (can be called Screen Timeout or Auto Shutdown).
4. Choose the maximum value available – it’s usually 30 minutes (on MIUI 15 it can be 10 minutes).

On some devices (such as the Redmi Note 11 Pro), this path may be slightly different:

Settings → Display → Additional → Sleeping mode

If you do not have the item Sleep mode, try to search by settings (the icon of the magnifier in the upper right corner).

⚠️ Attention: On Xiaomi with MIUI 14/15 maximum timeout can be blocked at the firmware level if you don't see the options anymore 10 minutes – go to the method with the developer mode.

Method 2: Developer Mode (Hidden Settings)

If standard options aren’t enough, you can activate developer mode and access additional options, a method that works on all Xiaomi models, including the POCO M5, Redmi A2 and Xiaomi’s flagship 14.

First, turn on the developer mode:

1. Go to Settings. → The phone.
2. Find the MIUI version and tap it 7 times in a row, and the notification will appear "You became a developer!".

The advantage of these apps is that they do not require root rights and are compatible with the latest versions of MIUI 15. However, keep in mind that the screen running at maximum brightness can lead to:

• ⚡ Accelerated battery discharge (up to) 1-2% momentarily AMOLED-screen).
• 🌡️ Overheating of the processor (especially on budget models such as Redmi) 10A).
• 👁️ Eye fatigue due to lack of pauses for blinking.

⚠️ Note: Apps like Keep Screen On may conflict with optimization MIUI. If after installation the phone started to brake - add the application to the list of exceptions to autorun (Settings) → Annexes → Permits → Auto-start).

2. Select the appropriate app (e.g. YouTube).
3. Apply for additional (or permission) permissions.
4. Find the option to Lock the screen or Ignore battery optimization.
5. Activate the switch Allow the screen to be turned on.

On MIUI 15, this path may look different:
