What to do
- Keep the phone within normal range of the watch, especially at home overnight.
- Turn Bluetooth off and back on on the phone.
- Forget the watch in the phone's Bluetooth settings, then re-pair through the companion app.
- Move away from routers, other Bluetooth speakers, or crowded Wi-Fi environments during testing.
- Update both the watch's firmware and the phone's operating system.
- Restart both devices completely, not just toggling Bluetooth.
When to call a pro
If disconnects continue after re-pairing and updates across different locations, the watch's Bluetooth antenna may be failing and worth a manufacturer support check.
