Screentimer on Xiaomi: how to set up auto-switch off and exceptions

Xiaomi’s smartphone screen is one of the main consumers of battery power. Even in standby mode, the display can stay active longer than necessary, reducing battery life. Fortunately, the manufacturer has provided flexible tools to manage screen time, from a standard sleep timer to advanced features like Autostart Resolution and Battery Optimization.

In this article, you will find step-by-step instructions for all MIUI versions (including MIUI 14 and HyperOS), as well as solutions to typical problems such as why the screen goes off too fast or does not turn off at all. We will look at the settings for both Redmi and flagship Xiaomi 13/14 models, taking into account their features. If you want to save power or, conversely, extend the display activity for specific applications (for example, YouTube or Google Maps), here you will find the current ways.

Why adjust the screen time?

Xiaomi smartphones default to a 30 second or 1 minute auto-shutdown timer, a trade-off between convenience and energy savings, but not always optimal. Here are the key reasons to change the settings:

• 🔋 Battery savings: Reducing the time to 15 seconds can extend autonomy by 5-15% (GSMArena tests for Redmi Note 12).
• 📱 Usability: When reading or watching a video, the short timer is annoying with constant switching on.
• 🛡️ Security: Automatic screen shutdown protects against accidental taps in your pocket.
• 🎮 Game mode: in games like Genshin Impact or PUBG The mobile screen should be active longer.

It is important to note that the AMOLED-screens (installed in Xiaomi 13 Pro, POCO F5) Even black backgrounds consume energy because of the pixels' backlight, so setting the timer is particularly critical for these models.

Standard way: adjusting the sleep timer

The basic method works on all Xiaomi devices, regardless of the MIUI version. Here's how to change the screen auto-switch time:

1. Open the Settings app (cog icon).
2. Go to the Screen (or Display in older versions).
3. Select the Sleep Timer (in HyperOS it can be called Auto-Switch off the screen).
4. Set your desired time: 15 seconds to 30 minutes (on some models, Never is available).

On the POCO X5 Pro and other devices with MIUI 14, the path may be slightly different: Settings → Always Active Screen → Sleep Timer.

Make sure your phone is over 20 times charged%|

Close all background applications |

Check if the energy saving mode is activated |

Restart your phone after changes (recommended)

⚠️ Note: On some firmware (for example, MIUI Global for Redmi 10) after the update, the timer settings are reset. If the screen starts to go out too quickly, check this setting first.

Advanced settings: exceptions for applications

It is often required that the screen does not turn off in specific applications – for example, while navigating in Google Maps or watching a movie on Netflix. MIUI There are two mechanisms:

1. Auto-start permits

This method allows applications to prolong screen activity even when blocked:

1. Open Settings → Applications → Application Management.
2. Select the application you want (such as Waze).
3. Slip the Permits. → Additionally. → Auto-start.
4. Turn on the switch and confirm in the pop-up window.

2. Battery optimization

For critical applications (messengers, navigators) disable optimization:

1. Go to Settings → Battery and Performance → Battery Optimization.
2. Select All Apps in the drop-down menu.
3. Find an application (such as Telegram) and install it without restrictions.

After this action, the screen will not go out while the app is active, but this can increase battery consumption by 3-7% per hour.

Hidden functions: adaptive screen and sensors

The new versions of MIUI and HyperOS have smart settings that automatically adjust screen time depending on the context:

• 👁️ Adaptive display: uses a front-facing camera to track your eyes. If you look at the screen, the timer resets. Activates in Settings. → Screen. → Adaptive display.
• 📱 Approximate sensor: on models with AMOLED (Xiaomi 14: The screen does not go out if the phone is on the table with the screen up.
• 🔄 Adaptive lighting: Auto-off time increases by 20–30% in the dark for eye comfort.

On the POCO X6 Pro and Redmi K70, the adaptive display only works with the Always Active Screen (AOD) mode on, which is due to optimizing power consumption for AMOLED+-matrixes.

💡

If the adaptive display doesn’t work, check the permissions for the System Settings app in the Special Access → Body Sensors section.

Problems and Solutions: The screen goes off too quickly or doesn't turn off

Even after you set it up properly, users are going to have problems, and let's look at the typical scenarios and how to fix them:

1. the screen is turned off before the set time

Possible causes and solutions:

• 🔌 Power saving mode: turn it off in Settings → Battery.
• 📲 Background apps: Some messengers (like WhatsApp) force the screen to go out. Check autorun settings.
• 🔄 Firmware error: Reset screen settings to factory settings (Settings) → System system → Resetting settings → Resetting screen settings).

2.The screen doesn't turn off at all

If the display remains active despite the timer:

• 🐞 Jammed app: Force it to close through Recent apps (swipe up).
• 🔧 Developer rights: check if the option Do not turn off the screen when charging is turned on (Settings) → The phone. → Version. MIUI — Tap 7 times to unlock the developer menu).
• 📡 Sensor problems: wipe the area of the front camera and proximity sensor with an alcohol napkin.

⚠️ Note: On Xiaomi with HyperOS (e.g. Xiaomi 14) the adaptive screen functions are turned off after resetting to the factory settings!

Adjustment through ADB: for experienced users

If standard methods don’t help, you can change screen time through ADB commands. This is true for custom firmware or devices with limited settings (for example, Redmi Go).

You'll need:

• 🖥️ Computer with installed ADB-driver.
• 📱 Included Debugging by USB on the phone (Settings) → The phone. → Version. MIUI — Tap 7 times, then additionally → For developers).
• 🔌 USB-TypeC Cable (original to avoid connection issues).

Commands to change the timer (enter in the command line or Terminal):

adb shell settings put system screen_off_timeout 30000 # 30 seconds


adb shell settings put system screen_off_timeout 60000 # 1 minute




adb shell settings put system screen_off_timeout 300000 # 5 minutes




adb shell settings put system screen_off_timeout 1800000 # 30 minutes

To return the standard settings:

adb shell settings delete system screen_off_timeout

💡

Use ADB only if you are confident in your actions. Wrong commands can cause the system to crash!

Comparison with other brands: which is better?

Xiaomi’s screen controls are more flexible than those of its competitors, but there are nuances.Compared to Samsung, Realme and Google Pixel:

Xiaomi’s main advantage is deep customization, even on budget models, for example, Redmi 12 can set up separate timers for charging and discharging, which the Samsung Galaxy A54 does not have.
