How to do with Mi Fitness App and Xiaomi Watch 2 Pro sync failure？

If you encounter a sync failure between the Mi Fitness App and your Xiaomi Watch 2 Pro, you can troubleshoot and resolve the issue step by step based on common causes, such as connection issues, software versions, and settings. Here's a detailed solution:
  1. Check the connection status between your watch and phone. Ensure Bluetooth is connected, then refresh the App multiple times while Bluetooth is enabled and the devices are within 1-2 meters of each other.
  2. Check your phone's network connection. If Wi-Fi is disconnected, reconnect. If syncing still fails even with Wi-Fi, switch to mobile data.
  3. Restart your phone's Bluetooth, or try restarting your watch.
  4. Check whether your phone's App version and watch firmware are up to date. If not, try updating them first.
  5. Enable App permissions (background running, location services) and disable battery optimization.
  6. Unpair the device, forget the device in your phone's Bluetooth settings, and then re-pair.
  7. Clear the storage on both devices, or uninstall and reinstall the Mi Fitness App.
  8. If all methods fail, back up your watch data and perform a factory reset.
If the problem persists, contact Xiaomi customer service for hardware support.
