Apple Watch Battery Drain

Hi

If you only updated your iPhone, it may help to also update your iPhone Apple Watch:

- Update the software on your Apple Watch - Apple Support

Otherwise, the following steps have helped to resolve issues with battery life for some users:

Try restarting both your iPhone and watch:

• Turn both devices off together, then restart your iPhone first.
• To turn your watch off: press and hold the side button until you see the Power Off slider; drag it to turn off.
• To turn it back on: press and hold the side button until you see the Apple logo.

If that does not help, next try unpairing and re-pairing your watch.

• The Watch app on your 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).
• Unpair your Apple Watch and iPhone - Apple Support
• 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 ever 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.

If there is, end the activity from within that app on your watch (not on your iPhone).
