Apple Watch battery drain after watchOS 11 Update

After installing watchOS 11 on my Series 8 watch the battery life has been very poor. Hasn't been 12 hours yet since I did it and I can already tell that there's an issue. Overnight the watch will use about 10% of battery. Last night it used over 30% and used another 5% while I was up for about 45 minutes.

Yeah, I noticed the same with my watch I came across while researching the issue 15 Apple Watch Battery Saving Tips on another thread, and it mentioned low power mode too. I tried the low power mode and the battery drain has improved for me as well. Worth sticking with it until the next update comes through. It’s been super frustrating, though!

That most recent post from someone who did the full wipe/reset and reinstall of their Apple Watch, only to have it revert back to having the same exact battery drain issue a week later is exactly why I refused to even consider doing that with my AW9. I've been down this road with Apple before.


This type of issue can't be fixed from the user's end. That is simply because there is something seriously wrong with the 11.01 Version of watchOS that Apple needs to address, and I Strongly believe that until that is done, all of these hoops people are willingly jumping through trying to get their watch to behave itself is just a waste of time. And I would go further to say it's probably causing more harm than good in the long run.

After an OS update, it's common to experience an increased battery drain as certain tasks related to the update continue in the background including indexing, you should only experience this increased battery drain for a few days before it goes back to normal.


If after a couple days, your battery is not back to normal, I would recommend unpair and repairing your Apple Watch with your iPhone ⇢ Unpair and erase your Apple Watch - Apple Support

If anything, the update to Watch 11.0.1 made the battery drain on my AW 9 even worse. The update also added a few new problems (My watch repeatedly asked for permission to allow access to Location for Weather and other Apps, and the Watch face I use, Infograph, "lost" the Weather and Music Complications, which then dropped out of the list of available Apps so that I couldn't replace them).


In another thread Ingo2711 suggested that I unpair and then repair my watch. I did so last evening, and am happy to report that my watch seems not to be draining its battery and the missing Weather and Music Apps have returned, been added to my Watch and my watch has only asked for permission to access my Location once today. While I'll keep an eye on things, 24 hours after unpairing and repairing my AW 9, all seems well and back to normal under Watch OS 11.0.1.
