If youβve tried the obvious, but the clock is still βdeadβ β this guide is for you.
1.Primary Diagnostics: Why Xiaomi Band 7 is Not Turned On
Before you start taking action, you need to rule out the simplest causes. Start by visually inspecting the device:

- π Give time to charge: if the battery is completely discharged, it may take up to 10 minutes before the indicator appears on the screen!
- π Test with another cable: use a knowingly working USB-cable from another device (e.g. Redmi Note) and sometimes the problem lies in the damaged wires inside the cable.
- π± Checking through the app: If your watch has ever synced with your phone, open Mi Fitness and check the charge level in the Devices section. If it shows 0%, it confirms battery life.

1. Connect to charging for 10 minutes
2 Hold the button for 20 seconds
3. If it does not work, disconnect from charging and repeat
4.After the reboot, wait for synchronization with Mi Fitness-->
If the forced reboot didnβt help, the problem could be deeper, in firmware or hardware failure, in which case try resetting via contacts (section 4) or checking the clock on another phone.
