Your Xiaomi, Redmi, or POCO screen goes out too fast? It's a standard power saving feature, but it can be adjusted or turned off altogether. Depending on the model and version of MIUI (12 to 14), there are several ways available, from basic settings to hidden settings for power users.
The problem is especially relevant when reading long articles, browsing recipes in the kitchen, or using your phone as a navigator. In this article, 5 proven methods, including settings, Developer Mode, and even third-party apps, we'll also look at why the screen can go out despite settings, and what to do about it.
⚠️ Important: Constant screen operation without sleep reduces battery life. AMOLED-displays (Xiaomi 13, Redmi) K60) The risk of pixel burnout is higher than IPS (POCO X5, Redmi Note 12).
1. Standard screen sleep time setting
The easiest way is to change the timeout in the basic settings, which works on all Xiaomi smartphones with MIUI 12-14 and Android 10-14.
Open the Settings app and go to Screen → Auto-Switch Off (or Lock and Password → Auto-Block on older versions). There are options from 15 seconds to 30 minutes available, as well as the option Never (on some models).
- ⏳ 15 seconds – minimum value, suitable for battery saving.
- 📱 30 seconds-2 minutes – optimal balance for most tasks.
- ⚡ 10–30 minutes – easy to read or navigate, but consumes charge.
- 🚫 Never – the screen goes out before manually switching off (may be absent on newer versions) MIUI).
If you never have an option, the manufacturer has restricted it to your model, in which case you can move on to the following options.
2. Developer Mode: Hidden Settings
For advanced users, there is a way to get around the limitations through Developer Mode, which works even if the standard settings don’t have the option of Never.
First, activate the developer mode:
- Go to Settings. → The phone.
- Click 7 times on the MIUI version (you are a developer!).
- Back to Settings → Additionally. → For developers.
Now find the option Do not turn off the screen (or Sleep timeout in English firmware) and set the value Never.
Press 7 times on "Version" MIUI"|Find "For Developers" in the settings|Enable "Do not turn off the screen"|Reboot the phone (optional)-->
⚠️ Attention: on some firmware (MIUI 14 for global version) this parameter may not be available. In this case, try an alternative method with ADB (described below).
3.Use of applications to hold the screen
If the system settings do not allow you to turn off the sleep of the screen, third-party software will help. Applications like Keep Screen On or Caffeine simulate user activity, preventing the display from turning off.
Install one of the apps from Google Play and follow the instructions:
- Launch the application and grant permission to Overlay over other windows (in the security settings).
- Activate the screen holding function (usually the Start or Enable button).
- If necessary, add the app to the autoboot so that it works after the phone restarts.
| Annex | Features | Cons |
|---|---|---|
| Keep Screen On | Simple interface, work in the background | Shows a notice in the curtain |
| Caffeine | Flexible time settings, support for Android 13+ | Premium version for some functions |
| Stay Alive | Works without root, support for exceptions for individual applications | A complex interface for beginners |
💡
If the app doesn’t work, check permissions in Settings → Apps → Special Access → Overlay over other windows and Battery Optimization (should be disabled).
4.ADB commands for forced sleep shutdown
For users who are ready to work with Android Debug Bridge (ADB), There's a radical way to turn off the sleep of the screen at the system level. USB-cable.
Instructions:
- Enable USB debugging in the developer settings (see Section 2).
- Connect your phone to your PC and open the command line (cmd on Windows).
- Enter the command: adb shell settings put global stay_on_while_plugged_in 3 This will turn off screen sleep when connected to charging.
- To completely shut down sleep (even on a battery) use: adb shell settings put global screen_off_timeout -1
Once the second command is executed, the screen will never go out until you reset the settings or change the value manually.This can cause overheating and accelerated battery wear!
To return the standard behavior, do:
adb shell settings put global screen_off_timeout 30000(where 30,000 is time in milliseconds, for example 30 seconds).
5. Alternative methods: smart watches and accessories
If you want the screen to stay on during specific actions (for example, when using the navigator), you can use Xiaomi Wear or other accessories:
- 📍 Navigation in the car: connect your phone to the tape recorder via Bluetooth – many firmware resets a sleep timer when you are actively connected.
- ⌚ Smart watches Mi Band: some applications (for example, Notify for Mi Band) allow you to control the screen from the clock.
Why does the screen go out despite the settings?
Frequent problems and solutions
Even after the change of settings, users experience an unexpected turn off of the screen, and here are the typical reasons and ways to fix them:
⚠️ Attention: Xiaomi with AMOLED-screens (Xiaomi) 12T, Redmi K50) Constant display operation at maximum brightness can cause pixels to burn out after 1-2 years.
| Problem. | Reason. | Decision |
|---|---|---|
| The screen goes out in 1-2 seconds. | The proximity sensor (for example, during a call) was activated | Wipe the sensor near the front camera or turn it off in call settings |
| Settings are reset after rebooting | MIUI restrictions for energy saving | Use it. ADB-Auto-run commands or applications |
| The “Never” option is not on the menu. | Restricting Firmware for Your Region | Install. EU-firmware or use ADB |
💡
The most reliable way is a combination of standard settings + It's a screen-holding app that gives you flexibility (you can turn it off if you need it) and doesn't require root rights.
