Power On XiaoMi Phone without POWER button

Buttons are easy fail part in phones. Can we power-up phone with POWER button failed? For XiaoMi (also RedMi) phones, we can power it up using Recovery mode.

Tested on Xiaomi Mi 10 Lite 5G running MIUI 13/Recovery 5.0

To enter Recovery mode when the phone is power-off:
(if your phone is in totally battery-low, charge it up in advance)
- Press and Hold the VOL-UP button
- Insert USB power cable
- until the Mi logo appear

The phone will power up in Recorvery Mode
- Use VOLUME to select Up/Down
- Use POWER key to confirm

To reboot in normal mode, select Reboot.

* DON'T select Wipe Data,
   it will erase all your data

For phone with POWER key failed, just wait for 2 minutes. It will reboot in normal mode.

Then:
> Settings
> Always-on display & Lock screen
> Enable Double tap to wake or turn off screen when device is locked
   (You can also enable Raise to wake)

Such that you can turn ON (unlock)  phone with double tap, no need POWER button.

To lock screen, tap Lock screen in Slide-down menu.

Now you can use your phone as normal without POWER button.
