How to make the screen not go out on Xiaomi smartphones: all ways

The screen of a Xiaomi, Redmi or POCO smartphone that goes out after 15 to 30 seconds of inactivity can be a serious obstacle - especially if you're reading long articles, following a recipe in the kitchen or using the phone as a navigator. By default, MIUI limits screen lighting time to save battery power, but it's not always convenient. Fortunately, there are several ways to turn off auto-switching, from standard settings to hidden features and third-party utilities.

In this article, we will discuss 7 working methods, including:

• 📱 Screen settings in MIUI (easiest)
• ⚙️ Developer Mode and Hidden Parameters
• 🔧 ADB-constant-lighting
• 📲 Apps from Google Play to extend screen time
• 🔄 Bypassing restrictions on new versions MIUI (14+)

Important: some methods require unlocking the bootloader or the rights of the superuser (root). We will mark such cases separately so that you can choose the safest option. OLED-Matrix and increase battery consumption by up to 30% – use the function only when necessary.

Standard MIUI settings: maximum latency

The most obvious and safe way to do this is to increase screen timeouts through the settings menu, which works on all Xiaomi smartphones regardless of the MIUI version (including MIUI 14 and HyperOS).

Instructions:

1. Open the Settings → Display.
2. Select Sleep Mode (or Screen Timeout in older versions).
3. Set the maximum value – usually 10 minutes or 30 minutes (depending on the model).
4. Confirm the change.

⚠️ Note: On some devices (e.g. Xiaomi 13 Pro or Redmi Note 12), the maximum value may be limited to 5 minutes.

2.Developer Mode: Hidden Options for Screen Control

If standard settings are not enough, you can activate the developer mode and access additional options. This method does not require root rights, but allows you to increase the timeout to 30 minutes or turn it off completely on some firmware.

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 (you will be notified “You became a developer”).
3. Go back to the main settings menu and open a new section for developers.

Now find the option Do not turn off the screen (or Stay awake in English). Activate it, now the screen will not go out when you connect to charging. ADB-team (see next section).

3. ADB-Teams: Forced timeout shutdown

For users ready for a deeper setup, there is a way to completely disable the auto-turn off screen via ADB (Android Debug Bridge), a method that works on all versions of MIUI but requires the phone to be connected to a computer.

Step-by-step:

1. Download and install Google’s Platform Tools.
2. Turn on the phone debugging over USB in the menu for developers.
3. Connect your smartphone to your PC and open the command line (cmd) in the folder with adb.exe.
4. Enter the command to check the connection: Adb devices must appear serial number of your device.
5. Use the command to turn off timeout: adb shell settings put global stay_on_while_plugged_in 3 where 3 — The “always on” mode (alternatives: 1 — only when charged, 0 — switched off).

⚠️ Attention: After restarting the phone settings ADB To make the changes permanent, you need to create an autostart script or use applications like Tasker.

4. Applications for permanent screen illumination

If you don't want to mess with your system settings, you can use third-party utilities. Google Play has several proven applications that mimic user activity or block screen shutdowns.

Top.-3 applications:

• 🔹 Keep Screen On is a simple utility with a widget for quickly turning on / off functions.
• 🔹 Caffeine adds a button to the notification bar to control backlighting. Supports exceptions for individual applications.
• 🔹 Stay Alive! – Advanced settings, including low battery life (requires permission to access notifications).

⚠️ Note: Applications may conflict with battery optimization MIUI. After installation, add them to the settings. → Annexes → Permits → Autostart and disable optimization in Settings → Battery → Optimizing the battery.

5. circumvention of restrictions on MIUI 14 and HyperOS

In the latest versions of Xiaomi firmware (starting with MIUI 14 and HyperOS), developers have tightened control over screen control. Standard methods may not work, but there are workarounds:

Method 1: Using the Game Turbo

The Game Turbo feature in MIUI allows you to block the auto-turning of the screen for games, and it can be applied to other applications:

1. Open Settings → Special features → Game Turbo
2. Add the app you want (such as Chrome or Google Maps) to your list of games.
3. Launch the application and activate Game Mode in the drop-down menu.

Method 2: Configure with Security App

In Chinese firmware (China ROM) there is a hidden option in the Security app:

1. Open Security. → Optimization → Cog badge (⚙️) → Auto-turn off the screen.
2. Choose Never or Maximum Value.

💡

If you have a Global ROM but don’t have a Game Turbo, try setting up MIUI+ through Settings → Connected Devices → MIUI+. This will expand your screen management options.

6 Root solutions: full control of the screen

Users with unlocked bootloaders and root rights have the most flexible settings available, and with applications like Magisk or Xposed Framework, you can completely disable screen timeouts at the system level.

Popular modules:

• 🔧 Screen Off Timeout (for Xposed) – Allows you to set any time or turn off timeout.
• 🔧 GravityBox – Advanced interface settings, including screen management.
• 🔧 Tasker + Secure Settings plugin – creating automatic rules (for example, “do not turn off the screen in Google Maps).

⚠️ Attention: Installing root rights voids Xiaomi's warranty and may result in the blocking of banking applications (due to the SafetyNet trigger). TWRP.

💡

Root solutions offer maximum flexibility, but require technical skills. ADB-commands or applications from Google Play.

7.Alternative methods: physical and software tricks

If neither of these methods works, you can use bypass tricks that mimic user activity:

• 🖱️ USB-Mouse: Connect the wireless mouse through OTG-Adapter. The cursor's motion will reset the screen timeout.
• 📡 Auto-Update widget: Add to the home screen a weather or currency widget with a refresh rate of 1 minute.
• 🎵 Music Playback: Run a track on Google Play Music or Spotify at minimum volume – some firmware resets timeout when playing media.

These methods do not cancel the auto-switching at the system level, but prolong the screen life by simulating activity, minus increased battery consumption (up to 10-15% per hour).
