How to reboot Xiaomi Mi 9: all the ways

Xiaomi Mi 9 series smartphones, despite their age, remain reliable devices, but even the most stable operating system MIUI periodically requires restarting services to work correctly. Users often face situations when the interface stops responding to touch, apps freeze or the screen goes out, but the device continues to work in the background.

Understanding how to reboot the Xiaomi Mi 9 is a basic skill that every owner of this device needs, and there are several methods, from regular shutdown through the menu to hardware reset with buttons that help in critical situations, and it is important to distinguish between these methods so as not to damage the file system and save personal data.

In this article, we will take a closer look at all the reboot options available, including hidden engineering functions and recovery modes. You will learn how to proceed if the touch screen has completely stopped responding, and what key combinations are relevant for the Mi 9 model with the Snapdragon 855 processor.

Staff reboot through the settings menu

The safest and most recommended way to turn off or restart a smartphone is to use the operating system’s software interface, which allows all active processes to complete their work correctly, save cache and close background applications without risking damage to the file system.

You should unlock the device and find the Settings app icon on your desktop, which usually looks like a gear. In the menu that opens, you should scroll down to the bottom of the About phone list. This is where, unlike many other Android smartphones, the MIUI shell hides power management features. Click on this section and you'll see some large control buttons.

Among the options available, you are interested in the Reboot or Turn Off button if you plan to completely turn off the device. The system can request a confirmation of action or enter a password to unlock the screen for security purposes. Once confirmed, the screen will display an animation of the shutdown, and then the device will automatically start again, which often solves problems with micro-hangs.

💡

If the screen reacts with a delay, try turning off Bluetooth and Wi-Fi first through the notification curtain to reduce the load on the processor before restarting.

Using a regular menu is especially important when you install new apps or change system settings. In this case, the Android operating system receives a signal to recheck the configuration of drivers and services. Ignoring a regular shutdown in favor of a hardware reset in such cases can lead to logical errors in the operation of RAM.

Forced reboot with power buttons

Situations where the software interface is completely unresponsive require more stringent exposure techniques. If the Xiaomi Mi 9 screen is out but the notification indicator is on, or the image is frozen and does not respond to touch, you need to use hardware buttons. This method simulates battery extraction, which was the norm for older phones, but is now implemented software through the power controller.

To perform a forced reboot, find the on button on the Mi 9, which is on the right side of the body. You need to hold this button and hold it for a long time — usually 10 to 20 seconds. Do not release the button immediately after the logo appears, wait for the full vibration and the Mi boot screen to appear.

It is important to understand the difference between short press and long hold: short press wakes up the screen or turns it off, medium hold (about 5-7 seconds) causes the action menu (switch off, reboot, flight), and prolonged retention (10+ seconds) ignores software locks and sends a direct signal to the power management chip.

⚠️ Attention: If after 20 seconds hold the button nothing happens, try to connect the smartphone to the original charger on the 5-10 You can do it again, and then you can do it again, and the battery's deep discharge can block the ability to turn on.

Use key combinations for Recovery Mode

In more complex cases, when standard system boot is not possible or a factory reset is required, Recovery mode is used. This is a separate software module written in a protected memory area that loads independently of the main MIUI operating system.

To get into the recovery menu, first make sure the phone is completely off. If it freezes, wait for the battery to drain, or use the forced reboot method described above to turn off the screen. Once the device turns off, simultaneously press the Volume Up and the power button. Hold both buttons until the Mi logo appears, after which the power button can be released while continuing to hold the volume key.

In the menu that appears, you can navigate using volume buttons (up and down), and the choice of item is confirmed by the power button. You will be asked to choose a language (usually English or Chinese) and go to the main menu. Here it is important to be extremely careful, since some options can lead to the deletion of all data.

If you see a menu with an image of Android repairing a robotic arm, or text No command, it means that you have successfully entered recovery mode, but the system is waiting for the command. In some versions of MIUI, you need to press the power button once to display the menu, and then the combination of Volume Up + Power. The main functions in this mode include data cleaning (Wipe Data) and return to the system (Reboot).

Reboot via computer and debugging via USB

For advanced users who have pre-enabled the Debugging function on the smartphone USB, It's a way of controlling the device through a computer, and it's particularly effective when the touch screen isn't working properly, but the system is functioning, and you can see the image on the display. ADB (Android Debug Bridge on PC.

Connect Xiaomi Mi 9 to your computer through high-quality USB-Open the command line or terminal on your computer in the folder with the installed ADB. Enter the adb device command to check the connection. If a window appears on your smartphone screen requesting debugging permission, confirm it using volume and power buttons if the sensor is not working, or simply tap the screen.

After successfully pairing to perform the reboot, enter the following command:

adb reboot

This command initiates a regular restart of the device if the system is deep-suspended and does not respond to the system. ADB-Teams, you can try the command to enter recovery mode:

adb reboot recovery

⚠️ Warning: Adb reboot bootloader will put the device into Fastboot mode, leaving it by holding the power button for a long time (about 15 seconds) until the phone vibrates and starts to boot in normal mode.

Using computer debugging not only allows you to reboot the device, but also access system logs, which is useful for diagnosing the causes of unstable work. However, for the average user who just needs to “revive” the phone, this method can seem excessively difficult compared to using physical buttons.

Table of loading modes Xiaomi Mi 9

To organize information about the various ways to control the status of the Xiaomi Mi 9 smartphone, it is convenient to use a summary table that will help you quickly navigate what key combination or action you need to perform in a particular situation. Different modes serve different purposes, from simple shutdown to deep diagnostics.

As you can see from the table, the Mi 9 supports the standard set of diagnostic tools for modern Android devices. Knowing the differences between Recovery and Fastboot mode is especially important, since inexperienced users often confuse them, trying to reset a password or update the system in the wrong way.

Fastboot mode, in particular, is characterized by a hare repairing an android, and is used primarily by service centers, and you can get into it by accident if you turn off the phone to press the wrong volume button. The exit from this mode is simple - prolonged retention of the power button, which is equivalent to removing the battery.

Solving the Problems of Cyclical Reset

One of the most frustrating problems that Xiaomi Mi 9 owners can face is the so-called “bootloop” in which the phone constantly displays the Mi logo, then goes out and shows the logo again before reaching the desktop, often caused by system file corruption, a failed update or software conflict.

If your smartphone is in this cycle, the usual holding of the power button will not help — the phone will go into reboot again and again. In this case, you should try to enter Recovery mode, as described in the section above (Loudness Up + Power). Once in the menu, select the language (English) and go to Wipe Data.

💡

Resetting data via Recovery (Wipe All Data) will completely remove all files, photos and contacts from the phone’s internal memory, a last resort if other methods fail.

Importantly, newer versions of MIUI may require you to enter a screen unlock password or Mi Account to confirm the data reset, a security measure against theft, and if you don't remember the password, it will be virtually impossible to restore access to the data without losing it without contacting an authorized service with a check of purchase.

After selecting the Wipe All Data and confirming the action (usually you need to press Confirm and wait a few seconds), the phone will clear the user partition. Then you need to select Reboot → Reboot to System. The first start after the reset can take up to 5-10 minutes, as the system creates new configuration files.

To sum up, the Xiaomi Mi 9 provides enough tools to manage your condition. From soft software to hard hardware resets, knowing these techniques will allow you to maintain control of your device in all situations. Remember that regular system updates and caution when installing applications from unknown sources reduce the likelihood of critical errors requiring a complex reboot.
