Q: Apple watch battery drain

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

- Update the iOS software on your iPhone, iPad, or iPod touch - Apple Support

- Update the software on your Apple Watch - Apple Support

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

• Restart both your iPhone and your 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 on: press and hold the side button until you see the Apple logo.

• Unpair and re-pair your watch:
  • The Watch app on your iPhone a backup of your watch automatically when unpairing via the app. Choose to restore the watch from backup when offered the option during set up. 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.

My only problem I see with the unpair and pair thing is that it will show more and more devices under the health app, then you gotta see which one the correct device aka apple watch and rename. Currently I have about 6 different apple watch devices showing. The reason I want to get rid of it is if you go under lets say "steps" then it will sync data from top to bottom. :-/ It gets to be a pain.

To clarify: this only happens if the watch is set up as a new watch, rather than choosing to Restore from Backup (which was suggested above). Even then, it has no practical impact on the syncing of data (as only paired watches share data to the Health app).
