When you need to reboot your smartphone
Xiaomi Redmi Note 9 Pro is a reliable device, but even it sometimes requires a reboot, most often when the interface freezes, when the screen does not respond to touch, or applications begin to spontaneously close, rebooting helps to clear RAM, close the background processes and return the device to stable operation.
Another common situation is after the MIUI update. New firmware versions may contain errors that only appear after the reboot. For example, after upgrading to MIUI 14, some users experience problems connecting to the mobile network or operating sensors, in which cases, the reboot often solves the problem without additional manipulation.
Keep in mind preventive reboots: If you actively use your smartphone for several days without turning off, the system may start to slow down due to accumulated cache files and temporary data. Regular reboot (every 2-3 days) helps to maintain optimal performance.
Method 1: Standard Reboot through the Menu
The simplest and safest method is to use a standard off menu, which is suitable when the smartphone responds to touch, but it is unstable.
- Press and hold the power button (located on the right end of the device) for 2-3 seconds.
- The screen will appear menu with three options: Turn off, Reboot and Emergency mode.
- Slip on the item Reboot and confirm the action if the system requests.
It takes about 30-40 seconds, and after you reboot, all your data and settings will remain intact, which is completely safe for the system, and if problems persist after you restart, you should consider other ways.

If the power button on your Redmi Note 9 Pro is unstable, try using the Volume Up + Power combination β this is an alternative way to trigger the off menu.
Method 2: Forced Reset (Hard Reset)
When the smartphone is completely frozen and unresponsive, a forced reboot is required, a technique that simulates battery extraction (although it is not removable in the Redmi Note 9 Pro) and resets all current processes. It is important to understand that this method does not delete your data, but can interrupt unsaved operations in applications.
To perform the forced reset:
- π Hold the power button for a while. 10-15 seconds until the screen goes out.
- π± If the device doesnβt respond, try the Volume Down combination. + Eating and holding on 10-20 seconds.
- β³ Wait after you're out. 5-10 seconds and press the power button to turn on.
This method is effective in 90% of freezes, and if the smartphone does not turn on after a forced reboot, the problem can be more serious, for example, the battery is discharged or the firmware is damaged.
What if your smartphone doesnβt turn on after Hard Reset?
Method 3: Reboot with Recovery Mode
If standard methods don't work, you can use Recovery Mode, which is useful when the system is damaged, but the smartphone can still boot into the service menu.
To reboot through Recovery:
- Turn off your smartphone (forced if necessary).
- Press the combination of Loudness up + Power and hold until the Mi logo appears.
- Release the buttons and you will see the Recovery menu in English.
- Use the volume buttons for navigation and the power button to select Reboot β Reboot to System.
If you see a No command error in Recovery Mode, don't panic - it's OK for Xiaomi's stock recovery.Just press the Volume Up + Power combination again, holding 5-7 seconds.
| Rebooting method | When to use | Implementation time | Risk of data loss |
|---|---|---|---|
| Standard menu | Smartphone responds to touch | 30-40 seconds. | No. |
| Forced (Hard Reset) | Full freeze, black screen | 10-20 seconds | No. |
| Through Recovery Mode | System errors, inability to load normally | 1-2 minutes | No (unless you choose Wipe) |
| Through ADB | For experienced users, debugging | 2-5 minutes | No. |
Method 4: Reboot through ADB (for power users)
If you are familiar with Android Debug Bridge (ADB), you can reboot your smartphone via your computer.This method is useful when physical buttons donβt work or you need to reboot remotely. Before using, make sure that the smartphone has USB debugging enabled (Settings β About Phone β MIUI Version β 7 times tap β Return to Additional Settings β Developers).
Instructions for restarting through ADB:
1. Connect the Redmi Note 9 Pro to your PC via USB- cable
2. Open the command line (Windows) or the terminal (Mac/Linux)
3. Enter a command to check the connection:
adb devices
4. If the device is detected, reboot:
adb reboot
For forced reboot (similar to Hard Reset):
adb reboot -pThis method is especially useful if you are testing custom firmware or recovering the device after a failure.Remember: command `adb reboot bootloader` Transfer the smartphone to fastboot mode, which may require additional actions to return to the system.

Method 5: Automatically Reboot on Schedule
Few people know, but MIUI has an automatic reboot feature built in, which is useful for maintaining system stability without manual intervention, such as setting up a weekly reboot at night when the smartphone is not in use.
To activate this function:
- Go to Settings β Additional settings β Planner.
- Select Automatic Reboot.
- Set the day of the week and time (it is recommended to choose the period when the device is connected to the charger).
- Activate the switch in the upper right corner.
This feature is especially relevant for users who forget to reboot their smartphone regularly. Auto-reboot helps prevent system errors from accumulating and maintains optimal performance. However, donβt set up too frequent reboots β once a week is enough.

Automatic reboot doesnβt reset your open tabs in your browser or unsaved data in apps β it works just like manually rebooting through menus.
What to do if the smartphone is not restarted
If none of these methods worked, the problem could be more serious than just hanging.
- π Battery discharged: Connect the original charger and wait 15-30 If the charging indicator is not on, try another charger or cable.
- π Power button problems: If the button doesn't respond, try connecting the smartphone to charge - sometimes this triggers automatic booting. + Loudness down + Eating at the same time.
- π± Damaged firmware: If there are errors on the screen like Fastboot mode or No. OS installed, you need to flash through the Mi Flash Tool. This is a complicated procedure, it is better to contact the service center.
β οΈ Warning: If after unsuccessful attempts to restart the smartphone began to warm or make unusual sounds (for example, a beep), immediately disconnect it from charging and do not turn it on until the diagnosis at the service center.
To diagnose hardware problems, you can use the test mode. To log in, type ##4636## in the Phone app. In the Test menu, check the sensors, speakers, and other components, and if the tests show errors, this confirms the need for repair.
