The power button on Xiaomi smartphones is one of the most vulnerable: it often breaks due to mechanical damage, moisture or wear of contacts. If your Redmi, POCO or Mi stopped responding to presses and the screen remains black or frozen on the logo, do not rush to carry the device into the service. In 80% of cases, the phone can be rebooted without a physical button using hidden Android features or hardware combinations.
In this article, we will look at 7 proven ways to force reboot, from simple (through charging or keyboard shortcuts) to advanced (using ADB or test points). Each method has been tested on Xiaomi 11T Pro, Redmi Note 10 Pro, POCO X3 Pro and other popular devices. Importantly, if the phone does not respond to any of the ways and does not charge, the problem may be in the power controller – here you will need repair.
1. Keyboard shortcut: how to reboot Xiaomi without a power button
The fastest way is to use hardware combinations, which works even if the screen is off, but the phone is not completely discharged (at least 5-10% charge), suitable for most Xiaomi, Released models after 2018.

| Xiaomi model | Key-clamping time | Sign of a successful reboot |
|---|---|---|
| Redmi Note 8/9/10 | 20-25 sec. | Vibration or flashing of indicator |
| POCO X3/X4 | 15-20 sec. | The appearance of the POCO logo |
| Mi 11/12 | 25-30 sec. | Loading sound or vibration |
