If the watch frequently disconnects from your phone, ensure the FitCloudPro app is not being put into "deep sleep" or optimized for battery saving by your phone's operating system. Adjust your phone's settings to allow the app to run in the background without restrictions.
6.2. Charging Problems
If the watch does not charge, check the charging port for dust or debris. Ensure the magnetic charging cable is properly aligned with the charging points on the watch. Try using a different USB power source.
