Smartphone screens are one of the main consumers of energy, and properly setting it off helps save battery power without losing convenience. On Xiaomi phones with a MIUI shell, there are several ways to manage display fade time, from standard settings to hidden features for power users. In this article, we will analyze all available methods, including nuances for different versions of firmware and models, from budget Redmi to flagship Xiaomi 14.
It’s important to understand that screen time is not only important for autonomy, but also for security: too long a timeout increases the risk of accidental taps in your pocket or access to notifications. On the other hand, too short a time can be annoying if you often read long texts or watch videos. We will show you how to find balance and adjust the behavior of the screen to your tasks – whether it’s saving battery, comfort reading or protecting privacy.
Standard screen timeout setting in MIUI
The basic way to change the screen time on Xiaomi is through the settings menu, which works on all devices with MIUI 12 and later, including the latest versions of MIUI 15 (HyperOS).
To set up a timeout:
- Open the Settings app (the gear icon on the desktop).
- Go to the Display section (or the Screen on some firmware).
- Select Sleep Mode or Screen Turn Off.
- Set the desired time from the available options: usually from 15 seconds to 10 minutes.
On new Xiaomi smartphones (such as Xiaomi 13T or POCO F6), an additional option called Adaptive Shutdown may appear on this menu, which automatically adjusts the timeout depending on your habits: for example, keeping the screen on longer if you are reading a book, and turning it off faster in standby mode.
- 🔄 Available timeout values: 15 s, 30 s, 1 m, 2 m, 5 m, 10 m (on some models up to 30 m).
- ⚡ Effects on the battery: Reducing time with 2 minute 15 It can extend the work for a second. 5-15% (model).
- 🔒 Security: Timeouts of less than 1 minute are recommended for data protection in case of phone loss.
- 📱 On the Xiaomi Pad and some tablets, the maximum time can reach 30 minutes.
⚠️ Attention: On devices with AMOLED-screens (e.g. Xiaomi) 12 Pro or Redmi K60) Too short a timeout can lead to premature wear of the matrix due to frequent on/off cycles — 30-60 seconds.
Advanced settings through the developer mode
If standard options aren't enough, you can activate the developer mode and access additional options.
- 🔧 Set a non-standard shutdown time (for example, 45 seconds).
- 🛠️ Turn off the screen during charging.
- 📊 Set up separate timeouts for different applications.
To enable the Developer Mode:
- Go to Settings. → The phone.
- Find the MIUI version and tap it 7 times in a row.
- Return to the main settings menu and a new section for developers will appear.
Now you can set up:
- 🕒 Screen waiting time – values up to 30 minutes are available here.
- 🔌 Do not turn off the screen when charging (useful for navigators or long-term video viewing).
- 📱 Debugging by USB — necessary ADB-teams (below).
Activate the mode (7 taps according to MIUI)
Go to Settings → For developers
Select "Waiting time for the screen"
Set the desired value (for example, 1 minute 30 seconds)
Save changes and restart your phone-->
⚠️ Note: On some models (Redmi Note 12, POCO X5) When you activate the developer mode, you may get a warning about an increased security risk. That's okay -- just confirm the action. USB, unless you plan to use it ADB!
Control screen switching off via ADB (for experienced)
If you need to completely turn off the automatic screen shutdown (for example, to use the phone as a monitor or to test applications), you can use the ADB commands. This method requires connecting the phone to the computer and basic knowledge of working with the command line.
Instructions:
- Install ADB on your computer (you can download from the official website of Android Developers).
- Connect your phone to your PC through USB-cable (turn on debugging by USB developer-like).
- Open the command prompt (cmd on Windows or Terminal on macOS/Linux).
- Enter the command to check the connection: Adb devices must appear serial number of your device.
- To turn off the screen, do: adb shell settings put global stay_on_while_plugged_in 3 This command will make the screen stay on only when charging.
To return the standard behavior, use:
adb shell settings put global stay_on_while_plugged_in 0| ADB Team Team | The effect | Application |
|---|---|---|
| stay_on_while_plugged_in 3 | The screen does not turn off when charging | Navigation, video viewing, testing |
| stay_on_while_plugged_in 1 | It does not turn off only when charging from the network (not from USB) | Use as a monitor |
| stay_on_while_plugged_in 0 | Standard behavior | Return to factory settings |
| settings put system screen_off_timeout 60000 | Set a timeout of 60 seconds (value in milliseconds) | Fine-tuning time |
What if the ADB can’t see the device?
Features of setting up on different Xiaomi models
Despite the general logic of MIUI, some Xiaomi models have unique nuances in screen control.
- 📱 Xiaomi 13/14 Series: Supports Adaptive Shutdown with user activity in mind. The screen settings have a separate switch for this function.
- 💡 POCO F/X series: In the firmware POCO Launcher screen shutdown time can be configured directly in the Quick Settings panel (swipe down from the top edge).
- 🔋 Redmi Note 12 and newer: Have a Super-Energy Saving option that forcefully reduces timeout to 15 seconds when charged low.
On foldable smartphones (Xiaomi MIX Fold 3), the screen settings are duplicated for internal and external displays, which means you can set different shutdown times for each screen, for example, the external screen can be adjusted to fast fade (30 seconds), and the internal screen can be adjusted to longer (5 minutes) for comfortable operation.
💡
On devices with AMOLED-screens (e.g. Xiaomi) 12T) Turn on Always-on Display in the screen settings, and it shows the time and notifications when the display is off, saving battery by highlighting only the pixels you need.
How to set up screen switching off for individual applications
Sometimes you need to keep the screen from turning off in specific applications, such as a navigator (Google Maps or Yandex.Navigator), a video player or a book.
Method 1: Built-in function "Do not turn off the screen"
Many apps (e.g. YouTube, Waze) have their own timeout option, which is usually found in the app settings called Don't Turn Off the Screen or Keep Screen on.
Method 2: Use of special utilities
If there is no built-in option, you can use third-party applications:
- 📱 Keep Screen On (Free on Google Play): Allows you to add apps to your whitelist.
- 🔧 Tasker (paid): Creates automatic rules for screen control.
- 🛠️ Caffeine: Adds a button to the notification bar to quickly turn off timeout.
Example of settings in Keep Screen On:
- Install the app from Google Play.
- Open it and enable access to Special Opportunities (confirmation required).
- Add the apps you want to see to the list (like Google Maps or VLC).
- Activate the function – the screen will not turn off in selected programs.
💡
When using third-party screen control utilities, watch for the resolution of "Overlaid on other windows." Some applications (for example, banking) may block such utilities for security reasons.
Solving the problems with turning off the screen
Sometimes the Xiaomi screen doesn't behave properly, it spontaneously shuts down too quickly, doesn't respond to settings, or doesn't go out at all. Consider typical problems and their solutions.
| Problem. | Possible cause | Decision |
|---|---|---|
| The screen turns off after 5 seconds despite the settings | Activated Super-Savings or Battery Optimization for System Applications | Turn off Battery Optimization for Settings and Launcher in the Battery menu → Optimization |
| The screen does not turn off automatically. | Failure of the proximity sensor or the application blocks the timeout | Check the sensor (call and hold the phone to your ear) or close all background apps |
| There is no “Sleep Mode” option in the settings | Outdated version of MIUI or custom firmware | Update the firmware through Settings → System Update |
| Timeout resets after reboot | Conflict with the application for cleaning memory | Add Settings to Auto Cleanup Exceptions |
If the screen started to turn off too quickly after the MIUI update, try resetting the display settings:
- Go to Settings → System → Resetting settings.
- Select Reset Application Settings (does not delete data!).
- After restarting, check the screen off time.
⚠️ Note: On some models (Redmi) 10A, POCO M4 Pro) after resetting, the Adaptive Shutdown option may disappear. To return it, update the firmware to the latest version via Settings → Updating the system.
