How to increase the screen shutdown time on Xiaomi: all the ways for MIUI 12-14

Why Xiaomi’s screen goes out too fast and how to fix it

You are reading an article on a Xiaomi smartphone and the screen suddenly goes out through the phone. 15-30 It's standard behavior in the system. MIUI, This is a type of content that annoys many users, especially when you have to look at static content for a long time (recipes, diagrams, instructions). 5 minutes, but there are ways to get around this limitation.

The problem is exacerbated by models with AMOLED-screens (for example, Xiaomi 13 Pro or Redmi) K60), where even minimal illumination with prolonged use can lead to a burnout effect. POCO or budget Redmi with IPS-The risk is minimal in matrices, the limitation is purely software. In this article, we will discuss all working methods for increasing the time of the screen shutdown, including hidden settings and commands for experienced users.

⚠️ Important: On some firmware (especially global versions) MIUI 14 for Europe) some methods may be blocked by the manufacturer.If your smartphone is not rooted, first check the available options in the standard settings.

Method 1: Standard screen settings in MIUI

To start with, the system's built-in options are the easiest, and this method will work for most models, including the Redmi Note 12, POCO X5, and Xiaomi 12T. Here's how to change the timeout:

1. Open the Settings app (cog icon).
2. Go to Always Active Screen and Lock (on some versions – Lock Screen).
3. Select Sleep Mode (or Screen Timeout).
4. Set the maximum value available – usually 5 minutes or 10 minutes (depending on the MIUI version).

🔹 Method limitations: On global firmware (e.g, MIUI Global 14.0.4) maximum value is often limited to 5 minutes, MIUI China) is sometimes available up to 30 minutes, but it depends on the model.

Method 2: Using 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, Redmi, and POCO smartphones running MIUI 12-14.

📌 How to Enable Developer Mode:

1. Go to Settings. → The phone.
2. Find the MIUI version and tap it 7 times in a row (you will be notified "You became a developer").
3. Go back to the main settings menu and open a new section for developers.

🔧 How to increase screen timeout:

1. In the For Developers section, find the option to turn off the screen when inactivity (or Sleep timeout in English firmware).
2. Choose the maximum value – on some firmware here, up to 30 minutes or even 1 hour are available.
3. If you don’t have an option, try finding Stay Active while charging – this will keep the screen from going out when you connect to the network.

⚠️ Attention: On firmware MIUI Europe (EEA) Some options in developer mode can be hidden due to limitations GDPR. This will only help with the method of ADB.

Method 3: ADB-commands to force timeout changes

If neither the standard settings nor the developer mode give the desired result, the most reliable method remains - changing the system parameters through ADB. This requires connecting the smartphone to the computer, but allows you to set any timeout value - up to completely disabling the automatic screen switch off.

🛠 What's the matter:

• 🖥 Computer with Windows/macOS/Linux
• 📱 Cable USB (better-than-original)
• 🔌 Included debugging by USB (see the instructions below)
• 📦 Android utility SDK Platform-Tools

📝 Step-by-step instruction:

1. Enable USB debugging in the developer settings (see Method 2).
2. Connect your smartphone to your computer and select File Transfer (MTP) mode.
3. Open the command prompt (or Terminal on macOS/Linux) and go to the platform-tools folder.
4. Enter the command to check the connection: Adb devices should appear the name of your device.
5. Set the right timeout (for example, 30 minute = 1800000 MS): adb shell settings put system screen_off_timeout 1800000
6. Reboot your smartphone.

🔄 Permissible timeout values (in milliseconds):

⚠️ Note: setting the value 2147483647 (approximately 24 days) actually turns off the automatic screen shutdown. AMOLED-Matrixes on models such as Xiaomi 13 Ultra or Redmi K50 Gaming. Use this option only when connecting to a charger.

Method 4: Third-party applications for screen control

If you don't want to mess with ADB or developer settings, you can use third-party utilities. They don't require root rights, but on some firmware, MIUIs can run unstable due to system constraints.

📱 Top.-3 timeout-management:

• 🔹 Keep Screen On is a simple utility with a widget for quickly turning on / off constant backlight.Works on most Xiaomi and other devices. POCO.
• 🔹 Caffeine – allows you to set rules for individual apps (for example, do not turn off the screen in YouTube or Chrome).
• 🔹 Screen Alive – supports automatic backlighting shutdown at low battery charge.

⚠️ Note: Keep Screen On Apps Could Conflict System Optimizations MIUI, especially on firmware with enhanced protection (e.g, MIUI 14 EEA). If after installation the screen starts to flash or spontaneously lock, delete the program and use the ADB-method.

💡 Tip: Before installing third-party utilities, check the reviews for your model. POCO F4 GT Some apps don't work because of the custom core.

💡

If you want the screen to stay on the screen only in certain applications (for example, in the navigator or book), use the Battery Exclusion function in the MIUI settings. Add the desired application to the exception list - the system will ignore the timeout while it is active.

Method 5: Modifying system files (for advanced users)

This method is only suitable for users with unlocked bootloader and root rights. It allows you to permanently change the system settings of the timeout, but requires caution - incorrect actions can lead to a "brick" of the device.

🔧 Instructions (for experienced only!):

1. Install a file manager with root support (such as Root Explorer or Solid Explorer).
2. Go to /system/build.prop and open the file in the text editor.
3. Add a line: ro.lge.proximity.delay=2500 pm.sleep_mode=1 (where 2500 — millisecond, 1 — time-out).
4. Save the file, set the rights 644 (rw-r--r---).
5. Reboot your smartphone.

⚠️ Note: Editing build.prop may disrupt some features MIUI, including air updates (OTA). Before the changes, make a backup copy of the file!

📌 Alternative path: On some firmware, timeout parameters are stored in /system/etc/device_features/. Look for files with type names display.xml or power.xml.

💡

Changing system files is the riskiest method. If you're not sure what you're doing, use ADB or third-party applications. Breaking the file structure can make it impossible to boot the system!

Risks of long-term screen operation: burnout and overheating

Increasing the time of the screen shutdown is a convenient feature, but it has the downside, especially for smartphones with AMOLED-matrixes (Xiaomi 13 Pro, Redmi K60, POCO F5 Pro), where prolonged illumination of static elements can lead to:

• 🔥 Burn-in – when the screen is left “shadows” from frequently displayed elements (navigation panels, status icons).
• 🌡 Overheating – especially when charging and using.
• ⚡ Accelerated battery discharge – the screen consumes up to 30-40% charge per hour at maximum brightness.

🛡 How to minimize risks:

• 📱 Use dark themes and read mode (gray filter) – this reduces the load on the computer. AMOLED.
• 🔄 Turn on the screen autorotation to allow static elements to change position.
• ⏱ Set a timeout of no more than 30 minutes and use it only when connected to a charge.
• 🔋 Watch the temperature of the smartphone – if the body is heated above 40°C, reduce the brightness.
