How to completely untie the Xiaomi watch from the phone: 5 proven ways

Xiaomi smartwatches are some of the most popular gadgets for tracking activity, but sometimes you have to untie them from your smartphone, for example, when selling a device, changing your phone or fixing synchronization errors.

Before you untidy the clock, be sure to follow these steps to avoid data loss or device lockdown:

• 📱 Synchronize data in an application (Mi Fitness or Zepp Life) and this will save the history of activity in the cloud.

If you plan to sell or transfer the watch to another person, make sure to reset to factory settings – this will delete all personal information, including health and payment information (for models with NFC).

⚠️ Note: If the watch is tied to your Xiaomi account (Mi Account) and you have forgotten your password, resetting may block the device.

Since 2022, Xiaomi has moved to the Zepp Life app (formerly Amazfit) to manage new devices.The uncoupling process here is slightly different:

5. Untie through the engineering menu (for experienced users)

If standard methods don’t work, you can use the engineering menu (only for models based on Zepp OS, for example, Xiaomi Watch S3).

1. On the clock go to Settings → About the phone.
2. Tap 5 times on the firmware version number until the message "Developer Mode is on" appears.
3. Go back to the settings and select a new section for developers.
