Xiaomi screen backlight time: full setup for comfort and battery savings

The screen of the Xiaomi smartphone is one of the main consumers of energy, and the correct setting of the backlight time can significantly extend the operation of the device from a single charge. Many users experience a situation where the display goes off too quickly or, conversely, stays on longer than necessary, which leads to inconvenience and unnecessary battery consumption. In this article, we will discuss all the ways to control the backlight of the screen on Xiaomi, Redmi devices and other devices. POCO, including hidden functions MIUI, which will help to optimize the display for your tasks.

It is important to understand that setting the backlight time is not only a matter of convenience, but also the key to durability. OLED-Matrices that lose their brightness over time due to pixel burnout, and we'll look at both the standard parameters on the menu and advanced methods through the use of the pixels. ADB And for those who want to automate the process as much as possible, here are examples of using embedded and third-party screen control applications.

What is the screen lighting time and why it needs to be adjusted

The screen backlight time (or lock timeout) is the interval at which the display automatically turns off when the user is inactive. By default, on Xiaomi smartphones, this setting is set for 30 seconds, but it can be changed in the range from 15 seconds to 30 minutes.

• 📱 For active use (social networks, instant messengers) – 15-30 seconds.
• 📖 To read or watch a video – 1-5 minutes.
• 🔋 Minimum time to save battery (15 seconds).
• 🔄 For continuous monitoring (e.g. navigator) – maximum time or timeout.

An incorrectly configured timeout can lead to two main problems:

1. Too short a time – the screen goes out while reading or watching content, which is annoying and requires constant unlocking.
2. It takes too long, the battery runs out faster. OLED-The screen wears out due to prolonged exposure to static elements (e.g. navigation panels).

On devices with AMOLED-screens (for example, Xiaomi 13 Pro or POCO F5) The longer static elements burn (such as icons in a status bar), the faster the matrix degrades. Therefore, for such models, it is recommended to set minimum comfortable times or use functions like Always On Display (AOD) dynamically.

Standard setting of the lighting time in MIUI

The easiest way to change screen lock timeout is through standard settings MIUI. The instructions are relevant for all modern versions of the shell (from MIUI 12 to MIUI 14) and most models, including Redmi Note 12, Xiaomi 12T and POCO X5.

Open the Settings.

Go to the Display.

Select Sleep After (or Time Out Locks in Older Versions)

Set the desired time from the available options

Confirm the changes-->

In some firmware, the path may be slightly different. POCO-In addition, if you don't find the right setting, try searching by settings (the magnifying glass icon in the upper right corner).

Note that tablets (such as the Xiaomi Pad 6) have longer default intervals, which is because they are more often used to view content in stationary mode.If your model is not in the table, follow the general path: Settings → Display (or Screen) → Time out/Sleep.

⚠️ Note: Some custom firmware devices (such as LineageOS or Pixel Experience) have standard settings MIUI In this case, the backlight time is adjusted via the Android menu: Settings → System system → Additionally. → Screen timeout.

Advanced settings through ADB (power-user)

If standard options are not enough (for example, you need to set a timeout of 10 seconds or completely disable it), you can use the command. ADB. This method requires connecting the smartphone to the computer and enabling the developer mode, but allows you to flexibly configure parameters that are not available in the graphical interface.

First, activate the developer mode:

1. Go to Settings. → The phone.
2. Find the MIUI version and tap it 7 times in a row.
3. Return to the main settings menu – there will be a new section for developers.

Next, connect the device to the PC, install ADB-drivers and execute the following command in the terminal to change the backlight time (in milliseconds):

adb shell settings put system screen_off_timeout 60000

Where 60,000 is millisecond time (60 seconds in the example) to turn off the timeout completely, use 2147483647 (maximum integer).

Once you have completed the command, restart the device to make the changes effective. Note that some firmware may reset this option after you update the system, so you will have to repeat the procedure.

⚠️ Attention: Disabling the lock timeout (screen_off_timeout 2147483647) can lead to accelerated battery discharge and overheating of the screen, especially on the OLED-Use this mode only when absolutely necessary (for example, to test or show content).

Automatic setting of lighting times using profiles

Manually changing the timeout is not always convenient, especially if you use your smartphone in different scenarios (home, work, street). MIUI There is a built-in performance profile feature that allows you to automatically change screen settings depending on the situation.

To set up a profile:

1. Open Settings → Battery and Performance → Performance Modes.
2. Choose one of the predefined profiles (Balance, Performance, Charge Savings) or create your own.
3. In the profile settings, find the screen timeout item and set the desired value.
4. Activate automatic profile switching according to schedule or geolocation.

For example, you can configure:

• 🏠 Home profile: 5 minutes timeout (for comfortable video viewing).
• 🚶 Street profile: 15 seconds timeout (for battery savings).
• 🚗 Navigation profile: timeout disabled (for permanent map display).

💡

If you're in your version MIUI There is no auto-switching profiles, use third-party apps like Tasker or MacroDroid, which allow you to create rules to change the screen timeout depending on the running applications, time of day or Wi-Fi connection.

For devices with Always On Display (AOD) (Xiaomi 13 Ultra or Redmi K60 Pro) you can further configure the display of time and notifications on the screen off. This is useful if you want to see important information without fully activating the display. → Always On Display and Lock and Select Display Style.

Optimizing the backlight to save battery

The screen's backlight time directly affects the device's autonomy, according to lab tests. DXOMARK, Reducing your timeout from 2 minutes to 15 seconds can increase your smartphone’s life by 5 to 15 percent depending on the model:

• 🔋 Set a minimum timeout (15 seconds) and use Double Tap to Wake to quickly turn on the screen.
• 🌓 Activate Adaptive Brightness in Settings → Display. → Adaptive brightness.
• 📊 Turn it off. AOD, If you don’t use it all the time (saves up to 3% charge per hour).
• 🔄 Use dark themes on the OLED-screens (black pixels do not consume energy).

On devices with OLED-screens (e.g. Xiaomi) 12S Ultra or POCO X5 Pro, enabling Dark Theme mode in combination with a minimum timeout (15 seconds) can increase autonomy by up to 20% compared to standard settings. OLED-The panels do not illuminate black pixels, which reduces power consumption.

If you often forget to turn off the screen manually, turn on the function of Lift to activate (Settings) → Display. → This will allow you to quickly turn on the display with the movement of your hand without pressing the buttons, and save charge thanks to a short timeout.

Solving problems with automatic screen shutdown

Sometimes users are faced with the fact that the screen goes off earlier than the set time or does not turn off at all.

• 🔄 System settings failure: Reboot the device or reset the display settings to factory settings (Settings) → System system → Resetting settings → Reset the display settings).
• 🛠️ Application conflict: Some programs (such as launchers or optimizers) may override timeouts. → Annexes → Permits → Changes in system settings.
• 🔋 Energy saving mode: In Ultra saving or Super saving timeout can be reset to a minimum. → Battery.
• 📱 Intimacy sensor damage: If the screen does not go out during the call, check the sensor with the test ##6484### (for some models).

If the problem persists, try updating your firmware to the latest version or resetting to factory settings (don't forget to back up your data!). 4PDA and XDA Developers often publish patches to fix screen control bugs on specific models.

⚠️ Note: If after the update MIUI backlight time reset and does not change through settings, try clearing the Settings app cache (Settings) → Annexes → Application management → Settings → This often helps to restore the functionality of hidden parameters.

Hidden MIUI features for screen control

V MIUI There are a few hidden features that allow you to control the backlight more flexibly, some of which are available through the engineering menu, others with special codes.

To access the engineering menu:

1. Open the Phone app.
2. Enter the code ##4636##.
3. Go to the Battery Information tab or Battery Settings (depending on the model).
4. Find options related to Screen Timeout or Display Power.

In some firmware available mode "Screen is always on" (not to be confused with the "Screen is always on") AOD), It's a device that allows you to keep the display active when you connect to the charger, so you can activate it:

1. Connect the device to the charger.
2. Enter the code ##7378423## in the engineering menu.
3. Select the option to stay awake while charging.

💡

Using an engineering menu can cause the device to work in an unstable way, so do not change the settings that you do not know the purpose of.

Another useful feature is adjusting the sensitivity of the light sensor, which affects the adaptive brightness, so if the screen is too dim or bright in automatic mode, try calibrating the sensor:

1. In the engineering menu, go to Hardware Testing. → Light Sensor.
2. Follow the instructions on the screen for calibration.
