Q: Apple Watch sudden loss of battery life - iOS 9.3.2

Hi

If you have not yet done so, it may help to also update your Apple Watch to the latest software:

Update the software on your Apple Watch - Apple Support

Otherwise, given that you have already tried restarting your devices in all combinations, it may help to unpair and re-pair your watch.

The Watch app on iPhone takes a backup of your watch automatically when unpairing via the app. When setting it up again, choose to Restore from Backup. Most data and settings will be restored, with some exceptions (eg Apple Pay cards, passcode).

- Set up your Apple Watch - Apple Support

For the best performance from your watch, keep both Wi-Fi and Bluetooth permanently enabled on your iPhone.

Also: if you have previously used any third-party fitness tracking apps (such as Strava) to record workouts, check whether there is presently a paused activity within any of those apps on your watch. If there is, end that activity from within that app on your watch (not on your iPhone).
