Apple Watch battery drains after updating to watchOS 10.1

Using series 5 watch. Since updating my watch goes to under 10% battery after about 9 hours. With watchos 10 it lasted 16-17 hours with AOD and minimal useage. Thoughts/suggestions (besides wait for next os)?

Dear all,

Let me share all the things that did NOT solve this problem and the one thing that DID solve this for me.

Background: iPhone 13 running iOS17, Apple Watch series 6, updated from WatchOS 9 directly to WatchOS 10.1.1 after which battery life dropped from 18+ hours to 8 hours, and this did not improve for several weeks.


What did NOT solve it:

  • updating to iOS 17.1.1 or 17.1.2
  • multiple restarts and hard resets of Apple Watch and iPhone
  • deleting all third-party apps from Watch, then rebooting iPhone and Watch
  • resetting all privacy and security settings (forcing each app to ask for access to location etc again)
  • unpairing Watch from iPhone, then repairing with iPhone and reinstalling from the last Watch back-up


What DID solve it for me:

  • unpairing Watch from iPhone, then repairing with iPhone as a new Watch.

The excessive battery drain was solved immediately. This procedure comes with great disadvantages, e.g. I lost all my watch-faces with edited choice of complications, I had to reconnect the Watch with my activity tracker app, I had to rearrange all app icons to the positions I prefer in the app viewer, I had to choose playlists of songs to be downloaded to Apple Watch again, I had to go through my Apple Watch settings and adjust these to my preferences, and probably a few more nuisances. Despite these, I am happy that my Apple Watch lasts through the day again...


I hope this helps some of you...
