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!

I've been seeing the same battery drain from apple watchOS 11 and 11.0.1, I have a series 6 AW. Today was especially bizarre, I noticed this morning around 10am it was at 10%, it was charged the previous evening around 6 to 8 pm. The screenshot shows a drain dump probably close to 9am. Really strange. Maybe I now have a battery issue?

My iWatch Ultra 1 normally has a battery drain over 2 days. After turning off Live Activities and turning off all but three apps for notifications, unpairing my watch twice, waking the iwatch by touch only and reducing brightness to its lowest setting, battery is discharging a tiny bit slower. Still very unacceptable. My iWatch battery health after Apple Store ran diagnostics is 93%.


This was yesterday. None of the Salt Lake City, City Creek store techies were even aware there was an issue. LoL


Must of been a memo from Apple HQ to deny everything related to the iWatch iOS update 11.0 being the culprit for such a massive battery drain.


Oh well… waiting for update.

Same issue with 1 year old SE. Apple Store had no clue..100% at 8:30 this morning, now at 3:15 pm, 10% doing literally nothing on the watch. They didn’t seem too concerned because their watches weren’t having issues. It’s driving me crazy! I’ve tried all the suggested fixes: unpair and repair, completely reset the watch. Nothing has helped with the exception on one day this week, it held charge all day. Then the next day, right back to the same problem!
