How to set the time to turn off the display Xiaomi: the complete guide

Modern Xiaomi, Redmi and POCO smartphones are equipped with bright and energy-efficient screens, which, however, consume a significant part of the battery charge. Standard system settings often involve automatically turning off the backlight after 15 or 30 seconds of inactivity, which can be uncomfortable when reading texts or viewing recipes in the kitchen. Users often face the need to change this setting to keep the device active longer or, conversely, go to sleep faster to save energy.

In the MIUI shell and the new HyperOS, power management algorithms can work aggressively, adjusting timers themselves depending on light or applications running. Understanding where the switches are hiding allows you to take control of the device. In this article, we will detail all the ways to control the sleep timer, including hidden settings and functions for developers.

Incorrect time slot configuration can lead to both fast battery discharge and random activation of functions in the pocket. So it's important to find a balance between comfort and autonomy of the gadget. We'll look not only at the standard menu paths, but also at the nuances of proximity sensors that can affect the behavior of the screen.

Standard way of setting up through the system menu

The easiest and safest way to change the time before going to sleep is in the basic Android settings, so you have to open the main menu and find the Settings section, then go to the Screen or Screen and Brightness category, where the main adjustment sliders are located.

In the list of parameters that opens, you need to find the "Sleep" item, clicking on it will open a list of available time slots. The standard set usually includes values: 15 seconds, 30 seconds, 1 minute, 2 minutes, 5 minutes and 10 minutes. The choice of a specific value is applied instantly.

⚠️ Warning: Setting a maximum value (10 minutes) or “Do not turn off” mode can lead to a significant battery consumption if you forget to lock your smartphone manually.

It's worth noting that on some models with AMOLED-matrix available options may differ. The system may offer shorter time intervals to prevent pixel burnout in a static image. If you don't see the desired value, it may be limited by the manufacturer for a particular model of the processor or firmware version.

Advanced settings and mode for developers

If you don't have the standard time range, you can use the engineer's hidden menu. The developer mode allows you to force the setting "Do not turn off the screen while charging or set custom timers." To activate this mode, go to About phone and quickly click on the build number 7 times (MIUI Version).

Once activated, a new section will appear in the settings menu, Additional or Advanced Settings, where you need to select the "Developers" option. In this list, look for the "Do not turn off the screen" option. Activation of this option allows the display to burn indefinitely while the device is connected to the power source.

Activation path: Settings -> About Phone -> (7 clicks according to MIUI) -> Additional -> For developers

Also in this section you can find settings related to animation and zooming, which indirectly affect the perception of the interface. However, be careful: changing unknown parameters in the developer menu can lead to instability and work of the system.

Always on Display and its impact on the timer

Owners of smartphones with OLED and AMOLED arrays have access to the Always On Display feature, which allows displaying time, date and notifications on the off screen, consuming minimal energy, a feature that can conflict with a regular sleep timer.

If you activate AOD, after the expiration of sleep, the screen does not go out completely, but goes into the display mode of the static screensaver. You can adjust the behavior of this feature in the Wallpaper and personalization -> Always on screen.

Using the 10 seconds post-lift mode is the best balance between functionality and power consumption: the screen only lights up when you pick up the phone and goes out after a short time, ignoring the system's standard sleep timer.

Problems with proximity sensor and autobrightness

A common reason why the screen goes out early or doesn't go out at all is because the proximity sensor malfunctions or is contaminated, and it's located at the top of the screen, often hidden under glass, and if it's contaminated or covered with a protective film, the system may think that the phone is near the ear.

You can use the engineering menu to diagnose the diagnosis. Type ##6484## in the phone book (or #4636## on some versions). In the CIT menu that appears, select the Proximity sensor test. Close the top of the screen with your hand and remove it - values should change from 5.0 to 0.0 (or vice versa).

• 📱 If the values do not change, try to wipe the top of the screen with a microfiber.
• 🛠️ Check if the sensor covers the cover or thick protective glass.
• 🔄 In some cases, calibrating the sensor through the same engineering menu (Calibrate button) helps).

⚠️ Note: If the sensor calibration does not help and the screen continues to behave chaoticly, you may need to replace the plume or screen module in the service center.

Third-party screen management applications

If the built-in HyperOS system is not enough for you, the Google Play store offers many utilities for flexible backlight management. Apps like Screen Timeout or Caffeine allow you to add a quick switch to the notification curtain.

These programs run on top of the system settings and can force the screen to be turned on in selected applications, for example, you can set the rule: "If you run YouTube or Book, sleep timer turns off," which is more convenient than constantly changing the settings manually.

However, it is worth remembering that third-party applications require permanent permits to work in the background, which can negatively affect battery life. In addition, aggressive optimization of MIUI can “kill” such processes, requiring additional auto-start configuration.

Battery Optimization and Extreme Modes

Xiaomi systems are famous for their aggressive energy savings. The Battery -> Settings (or three dots in the corner) section often includes the option to save energy in sleep mode. It can ignore your time settings and extinguish the screen faster if the battery is low.

There's also an "ultra-mode" energy saving that limits the phone to basic functions and minimizes screen time, so if you notice that the sleep timer resets itself, check if one of these modes is activated.

• 🔋 Turn off Advanced Energy Savings if you want full control of the display.
• 📉 In Battery mode (average savings), sleep time can be limited to 30 seconds.
• ⚡ Full charge and power-off return standard intervals.

💡

For maximum screen time on the journey, turn on the dark theme and reduce the refresh rate to 60Hz in the screen settings.

Frequently Asked Questions (FAQ)

💡

The optimal time to turn off the display for the balance between comfort and battery is 1 or 2 minutes, which is enough for most tasks, but not critical for charging when you accidentally forget the lock.
