When your Android device is restarted or you have just powered it on after charging the device, it may take several minutes for the devices to register with one another. This is a common on Android devices.
If you have paired your bluetooth device and it is appearing in the Connected section of Connected Devices but the battery life is not updating and your steps are not syncing please give the device 5 - 10 minutes to allow them to reconnect.
If they have not reconnected in over 5 minutes, you can:
- Turn bluetooth on and off to reset the connection
- Re-pair the device
- Click on the device
- Select Forget
- Select the device under Available
- Follow the screen prompts to reconnect the device
