How to forcefully turn off Xiaomi Mi 8: solutions

The situation when Xiaomi Mi 8 stops responding to touch screen, familiar to many owners of this popular smartphone. MIUI interface can freeze at any time due to overflow of RAM or a malfunction in the operation of a particular application. At such moments, the only solution is a forced reboot, which allows you to reset all processes and bring the device back to life.

There are several proven ways to perform hard reset without losing personal data. We'll look at the standard methods through the case buttons, as well as more sophisticated options for advanced users, including the use of debugging commands. It's important to understand the difference between a conventional shutdown and an emergency restart.

Before you start physically impacting the buttons, you should evaluate the condition of the device, and if the screen is on but the touchscreen is not working, you can try to trigger the shutdown menu with software, but in 90% of cases, when the system is completely locked, you need to physically interact with the control buttons.

⚠️ Warning: Forced shutdown doesn't delete your files, but stored data in open applications will be lost.

Standard method of button reboot

The most common and safe way to revive the Xiaomi Mi 8 is to use a combination of hardware keys. On the case of the smartphone, the power button is located on the right side, which makes it easy to press it with the thumb of your right hand.

Unlike a short press that wakes up the screen, a forced shutdown requires holding the power button for a long time, usually between 10 and 15 seconds, at which point the system ignores the software locks and forcibly cuts off the power to the processor.

Once the screen goes out, release the button. In a few seconds, the vibration or the Mi logo will tell you that the boot process has started anew, and this method works even when the smartphone battery is almost completely drained, as it initiates a hardware reset of the power controller.

Sometimes a one-time tap is not enough if the system is stuck in a waiting cycle, in which case the procedure can be repeated, and if after 3-4 attempts of 20 seconds long, there is no reaction, perhaps the problem lies in the deep discharge of the battery or hardware damage to the plumes.

Combination of volume and power buttons

If standard power button retention fails, you can use an extended key combination. This method often helps when the MIUI software layer completely blocks the response to single signals. You need to use both volume buttons simultaneously with the power button.

Press the volume button (top on the right end) and the power button at the same time. Hold them for about 10-12 seconds. In some versions of the firmware, this action triggers the Recovery menu, from where you can choose to reboot, but most often it just initiates an emergency power reset.

An alternative combination is to press the volume down button and the power button, a bundle on Xiaomi devices that is often used to enter Fastboot mode. If your phone is getting stuck during an app update or installation, logging in to this mode may be the only way to recover.

It is worth noting that on the Xiaomi Mi 8, the buttons are ergonomically positioned, but when using a protective case, access to them can be difficult.Make sure you press hard enough to feel the tactile click of the mechanism, especially if the case has thick sides.

Using the Recovery Menu to Reboot

Recovery is a separate mini-interface, stitched into the device’s memory regardless of the main operating system, and can be accessed even when the touchscreen is completely broken using only physical buttons, a powerful diagnostic and forced restart tool.

To enter this menu on the Xiaomi Mi 8 switched off (or got stuck), press the power button and volume button. Hold them until the Mi logo appears, then release the power button, but continue holding the volume button until the English menu appears.

In the menu that appears, you can navigate with volume buttons (up-down), and select the item with the power button. Select Reboot, then Reboot to System. This action will force you to complete all the processes and start Android again, avoiding possible download errors.

Using Recovery is safe for user data if you only choose to reboot. However, be extremely careful with the Wipe Data option, as it will irrevocably delete all information from the internal memory of the smartphone.

Reboot via computer and ADB

For users who have previously activated debugging mode via USB, there is the most elegant software way to turn off: If the Xiaomi Mi 8 screen is working, but the touchscreen does not respond, or if the phone is getting stuck in a loop, but the computer sees it, you can use the ADB utility (Android Debug Bridge).

To do this, connect the smartphone to the computer through USB-Open the command line on the PC in the folder with the drivers installed ADB. Enter a command to check the connection:

adb devices

If a device with device status appears on the list, the connection is established. For a forced reboot, type the following command:

adb reboot

This command sends a signal to the kernel to restart immediately, and unlike hardware shutdowns, this method passes through software controllers, allowing the file system to be closed correctly, and if the phone freezes dead and does not respond to ADB, then only the command to shut down completely is left:

adb shell reboot -p

💡

For work. ADB You must pre-install "Debugging by USB" In the "Developers" section of the phone settings, without which the computer will not be able to control the device.

The advantage of the ADB method is that it doesn't require physical pressure on the buttons, which is useful if the mechanical controls are damaged or stuck, but without prior adjustment, this method is not available.

What to do if the phone does not respond

There are times when the Xiaomi Mi 8 doesn’t respond to any combination of buttons, the screen is black, and there’s not even a charging indication. First of all, you need to exclude the deep battery discharge. Leave the device on charge for at least 30-40 minutes, even if the indicator does not light up immediately.

If the phone still doesn't show signs of life after charging, try the shock charging method. Connect the phone to a powerful charger (not to the charger). USB-port of the computer), press the power button and hold it without letting go, during 30-60 Sometimes it helps to rock the power controller.

⚠️ Warning: If the phone heats up when connected to the charger, but does not turn on, there may have been a short circuit inside the board.

It's also worth checking the integrity of the charging cable and the power supply. đủ You can start the system, even if it's connected to the grid.

In rare cases, removing the back cover and turning off the battery plume for a couple of minutes helps, but the Xiaomi Mi 8 has a glass case and a complex opening system, so without repair skills it is better not to risk the integrity of the case.

Prevention of system freezes

Frequent freezes requiring forced shutdowns may indicate memory problems or overcrowded storage. Regularly clean the app cache and delete unnecessary files. The built-in Cleanup tool in the Security app helps keep the system on top.

Keep an eye out for updates to the MIUI operating system. Developers often release patches that fix bugs that cause unstable work. Go to Settings → About Phone → MIUI version to check for updates.

💡

Regularly restarting your phone (once a week) in normal mode helps to clear RAM and prevents the accumulation of system errors.

If the phone starts to freeze after installing a particular application, remove it. Conflicting software is one of the most common causes of software failures. Also, you should not ignore the overheating of the device, since high temperatures directly affect the stability of the processor.
