How to reboot Xiaomi Redmi 9 if the power button does not work: all ways

Broken power button on Xiaomi Redmi 9 is a common problem, but not a critical one. Even without physical access to the power key, you can reboot the device using software functions, hidden combinations or a PC connection. The main thing is not to panic and choose the method that suits your situation.

Many users mistakenly believe that without the power button, the smartphone becomes a “brick.” In fact, the manufacturer has provided several alternative ways to control power, including gestures, commands via ADB and even a forced reboot via the charger. In this article, we will analyze all current methods, their pros and cons, and give recommendations on how to avoid repeated problems.

If your Redmi 9 is frozen or needs to be restarted, but the power button is not responding, don't rush to bring it to the service. In 80% of cases, the problem can be solved by yourself in 5-10 minutes. It is important to assess the state of the device correctly: whether the screen is working, whether the sensor is responding, whether the smartphone is connected to the computer.

1. Reboot via the settings menu (if the screen is running)

The easiest way is to use the built-in MIUI features, which is fine if the smartphone is on, the screen responds to touch, but the power button is broken or stuck.

Instructions:

1. Open the settings (cog icon on the desktop).
2. Scroll down and select About Phone.
3. Slip on the item Reboot (in some versions Reboot).
4. Confirm the action in the dialog window.

If there is no reboot, try an alternative route:

• 🔄 Keep your finger on the off button in the notification curtain (swipe down from the top edge of the screen).
• 📱 Some firmware has a separate button Reboot next to Flight Mode.
• ⚡ If the curtain does not open, try to summon it with a gesture (swipe down with two fingers from the upper edge).

Make sure the battery is >15% |

Close all applications (double tap on the Home button)|

Connect to Wi-Fi (if you plan to upgrade after the reboot)|

Save open tabs in the browser

⚠️ Attention: If the smartphone does not turn on after the reboot, the problem may be a firmware or hardware malfunction.

Forced reboot through the charger

If the screen is unresponsive or the smartphone is completely frozen, you can try hardware reset via the charging connection, which works thanks to the features of the Redmi 9 power controller.

Step-by-step:

1. Connect your smartphone to the original charger (preferably from Xiaomi with Quick Charge support).
2. Leave it to charge for 10-15 minutes (even if the indicator is not on).
3. After 15 minutes, turn off the charging and immediately connect again.
4. Repeat disconnect / connection 3-4 times with an interval of 5 seconds.

🔋 Why does it work? The Redmi 9 power controller can initiate a reset at high voltage surges, and this method doesn't guarantee 100% success, but it helps in 30-40% of freezes.

⚠️ Note: Do not use uncertified chargers with output current >2.4A This can damage the power controller and exacerbate the problem.

3.Reboot via ADB (for advanced users)

If you have access to your computer and USB debugging is enabled, you can reboot your smartphone via the ADB command. This method requires pre-configuration, but gives you full control of the device.

What you need:

• 🖥️ A computer with installed Xiaomi drivers and ADB.
• 📱 USB-cable (preferably original).
• ⚙️ Included debugging by USB (Settings → The phone. → Version. MIUI → 7 times tap to activate the developer mode, then enable debugging).

Instructions:

1. Connect your smartphone to your PC.


2. Open the command line (Windows) or the terminal (macOS/Linux).




3. Enter the command:




adb devices




(Your device should be displayed)




4. Perform a reboot:




adb reboot

If USB debugging wasn't enabled in advance, this method won't work, so try the other ways in the article.

To avoid problems in the future, enable debugging over USB in advance, which will help control the smartphone even when the power button is not working.

• 📱 If there is no gesture, check the settings in Settings → Additionally. → Gestures.

Method 2: Voice command
