How to turn off the screen Xiaomi: full instructions

Managing the power consumption of a smartphone is a key skill for any owner of a modern gadget, especially if we are talking about the functions of Xiaomi devices. The screen is one of the most energy-intensive components, and its improper operation or constant activity can significantly reduce battery life. Users often face the need to completely extinguish the display, lock the sensor or disable functions that leave the image active in standby mode. Understanding the mechanisms of controlling the backlight allows not only to save charge, but also to extend the matrix life.

There are many scenarios where you need to force or automatically turn off the screen, which can be due to the desire to remove distractions, the need to leave the phone on for loading but with the display turned off, or the solution of problems with sticking buttons. The MIUI operating system and its global version of HyperOS have different levels of locking, from simply quenching the backlight to completely turning off the sensor.

In this article, we will take a look at all the screen controls available, including standard timer settings, proximity sensors, Always-on Display features, and even specific engineering menus, and learn how to effectively manage the display power while avoiding common errors that can lead to battery drain or random calls. A deep understanding of these processes will make smartphone use a more comfortable and predictable experience.

Standard sleep timer and lockdown settings

The basic tool for controlling the state of the display is a sleep timer. This is a setting that determines the period of inactivity after which the system automatically extinguishes the backlight. You can find this parameter by going to Settings → Screen and brightness → Sleep mode. Here the user is asked to choose a time from 15 seconds to 10 minutes. The optimal value for the balance between convenience and energy savings is considered to be an interval of 30 or 60 seconds.

However, some applications can block sleep mode. Video players, navigation cards and games often require constant screen activity, ignoring system timers. In such cases, the screen only goes out after the sesi is completed in the application or when you manually press the power button. If you notice that the screen does not go out in normal conditions, check if an application with sleep prevention permission is running in the background.

⚠️ Setting a maximum sleep timer (10 minutes) can lead to significant battery consumption if you often forget to lock your phone manually.

To fine-tune the screen's behavior when inactivity, you can use the Pocket Dial Mode feature, which also affects sensor response. Although its main task is to prevent random calls in the pocket, it is closely related to screen-quenching algorithms. In some versions of MIUI firmware, an option is available called "Increased Timer", which extends the time to shutdown if the light sensor believes that the device is in bright light.

💡

A short sleep timer (15-30 seconds) is the most effective way to save energy in everyday use.

Use of power button and lock gestures

The most obvious and quick way to turn off the screen is to use a physical power button, which is on the right or upper edge of the case on most Xiaomi and Redmi models. Short tap instantly puts the device into lock mode, quenching the display and suspending background processes that do not require an active screen, this action is a priority and works independently of the applications running.

For users who prefer touch, Double-Tap to Lock is available. You can activate it from the Settings menu → Additional settings → Screen lock. Once you turn on this option, you just need to touch the empty area on your desktop or lock screen twice to extinguish the display. This is especially convenient on devices with large diagonals, where it is difficult to reach the power button.

• 🔘 Physical button: Guaranteed to lock the screen and sensor in any situation, including interface freezes.
• 👆 Double-tape gesture: A convenient software alternative that requires inclusion in settings and works only on the desktop.
• 🖐 Gestures without a button: On models without a physical button, the lock is swiped upwards at the bottom of the lock screen.

There is also the option of locking the screen through the control panel. Swipe down from the upper right corner opens the control center, where the lock widget or the off button is often located. In addition, on some models with support for Always-on Display, prolonged pressing on the lock icon in the control center can cause a menu with a choice of time before the screen is completely turned off.

Disable the Always-on Display and Indicators

Always-on Display (AOD) technology allows time, date and notifications to be displayed on a screen that is off using OLED-matrix features. While it looks spectacular, it consumes battery power and essentially prevents the screen from completely shutting down in the traditional sense. For those who want to achieve full black screen and maximum savings, this feature needs to be turned off.

AOD is managed through the Settings menu → Screen and brightness → Always-on Display and lock screen. Here you can not only turn off the function completely, but also adjust its schedule. For example, you can set the display only one day or 10 seconds after touching. Complete shutdown ensures that after the expiration of the sleep timer, the matrix will go to a state of complete rest.

⚠️ Attention: AMOLED-A static image at low brightness can cause pixels to burn out after several years of use. AOD extends the life of the matrix.

Also worth paying attention to is the notification indicator. On some Xiaomi models, the LED indicator or light bar can flash when messages arrive, even if the screen is turned off. This is not the display, but visually creates an activity effect. You can turn off the light indication in Settings → Notifications and Status bar → Light indicator.

💡

Use the Always-on Display schedule to keep the feature running only during business hours, saving charge at night.

Touch-Input Lock (Pocket Mode and Child Protection)

Often, by “turning off the screen,” users don’t mean blocking the image, but locking the touch layer, which is necessary to avoid accidental taps when the phone is in the bag or when the device is used by a child. Standard lock mode (with or without a password) already solves this problem, but there are specialized tools.

The Pocket Mode feature uses a proximity sensor to lock the sensor when the phone is in the dark and close to the object. If the screen catches fire in your pocket, hold the top of the phone (where the sensor is located) to the dense fabric or palm for a couple of seconds - the screen should go out and lock. If this does not happen, check the cleanness of the sensor and settings in the Settings → Screen Lock menu.

To completely lock the interface while keeping the application running, Guided Access is ideal. Once you turn it on, you lock the screen on one app, lock the control buttons and touch zones. To activate this mode, go to Settings → Digital Well-Being → Parental Control or use the built-in Security app.

• 🛡️ Child Protection: Allows you to block the exit from the application and disable the system buttons.
• 📵 Pocket mode: Automatically locks the sensor when objects are near, preventing "pocket" calls.
• 🔒 Windows Lock: A feature in the multitasking menu that allows you to pin one application on the screen.

Special opportunities and energy saving regimes

MIUI has powerful screen controls hidden in the special features section. One-Hand mode not only reduces the size of the image, but can also change the lock behavior. Moreover, activating the power saving mode automatically limits background activity and reduces the time to turn off the screen, ignoring some user settings.

There is also a Remote Assistant feature that is sometimes required for diagnosis, but can keep the screen active while waiting for the connection. Make sure that the Settings menu → Additional settings → Special features do not activate services that require constant display of the interface. Disabling unnecessary accessibility services is an important step for the stable operation of the screen control system.

In emergency cases, when the interface is not responsive, you can use key combinations to force a reset or emulate a shutdown. Pressing the power button for 10-15 seconds leads to a hardware reset, after which the phone will turn on with the screen completely off at the boot stage. This is a last resort, but it is effective for software failures that block the display quenching.

Comparison of screen control methods

To systematize the knowledge of the different ways to turn off and lock the screen, consider their comparative characteristics. Each method has its advantages and use cases. Understanding the differences will help you choose the best strategy for a particular situation, whether it is saving battery or protecting against children.

As you can see from the table, the combination of methods works best: using a sleep timer in conjunction with a power button balances convenience and autonomy; using features like AOD is a selective way to understand their impact on battery life; and for users who are critical to a complete shutdown, manual control and back-end activities should be a priority.

⚠️ Warning: Installing third-party screen control apps ("black screen", "blockers") often leads to system conflicts and increased charge consumption due to constant background processes.

Solving problems with non-extinguishing screen

If your Xiaomi screen stops turning off on its own or goes out with a delay, the problem may lie in the calibration of the light sensor. Dirt, a low-quality protective film or a magnetic case can block the sensor, making the system think that the phone is in the dark or, conversely, in bright light, which changes the algorithms of the timer.

It’s also worth checking the list of apps that have the “Do Not Turn Off Screen” permission.This setting is often turned on automatically for navigators, readers, and instant messengers. Follow the Settings path → Apps → All Apps → (three dots in the corner) → Access to special features (or a similar path in your version of MIUI) and make sure no app abuses that right unnecessarily.

In rare cases, the cause can be a software failure. Resetting to factory settings (pre-backup) helps to eliminate deep configuration errors. However, before this step, it is recommended to simply restart the device in safe mode to eliminate the impact of third-party software. If in safe mode the screen goes out correctly, then the problem is in one of the applications you install.
