Apple Watch battery drain after watchOS 11 Update

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! 

Same error with my AW8. Before watchOS 11 I had a runtime of 1.5 days, now 12 Hours.

Apple Watch Ultra, Watch OS 11.0. Went to bed with a fully charged watch and by 11 am this morning it was down to 10%. I was getting a solid 2 days prior to the update.

My Apple watch 10's battery life just got even worse with update 11.0.1

As probably mentioned before, everybody having issues with the battery life after the watchOS 11.0 upgrade, should use the Feedback link to tell Apple directly about it:

Apple does not follow these discussions, and this is the only way to make them aware of such problems.

Feedback - Apple Watch - Apple

"Disabling Live Activities seems to have solved it. "

Being forced to disable features you were previously using in order to get the same battery performance you had before an OS update can hardly be considered a viable fix to a problem.

I have AW6 Cellular and faced issue of battery draining by 50% since installation of watchOS 11.

After disabling “Smart Stack” the issue seem to have resolved.

Yeah...This is the WORST battery issue I have had with an Apple product in recent memory, and I own at least (1) device in every major product category Apple currently offers!

My 45mm Series 9 just turned 1 year old last week and until these latest 11.0 and 11.01 updates I was more than satisfied with the battery life. I have always charged my watch back up to 100% at around 5:30PM every night with about 15% to 25% battery charge remaining when I would place the watch on my charger stand most days.

Now I am getting battery charge alerts hours before the usual charge time with often less than 10% battery remaining as early as 3:30PM! The watch can not currently make it through a full 24 hour period without coming very very close to being at 0% charge remaining! Since I am not usually back at home until after 5PM, there is no simple way to charge my watch back up so much earlier than my usual 5:30PM schedule. Apple really needs to get to the bottom of this ASAP since the current situation has destroyed my Apple Watch's viability as my daily driver!

And before anyone chimes in with the usual finger pointing away from the actual cause of the issue at hand...

I have changed NOTHING on my watch in terms of software and typical use case. The only thing that has changed has been the recent update to 11.0 and then recently to 11.01. This situation is not sustainable for the majority of us out here who rely heavily on this product's ability to run a full 24 hours between charges!!!

I’ve had it for a week and still no change to battery life. Performs the same as described above. 25% loss overnight while sleeping.

No seriously, like I noticed over night my battery about 30% too (Apple Watch SE) (when it typically would only go down 4-5% while wearing it sleeping) and whenever I would go to school on a full charge, I would come home with out 50-60% (school lasting from 8-3, coming home at 4) however I noticed today, my battery was at 24% and I went to school on a full charge. Thought it was just me over the weekend, but no, the battery is draining extremely fast.

I have an Apple Watch SE (GPS 2nd edition)

I also noticed the same thing.

I charge it overnight put it on my wrist within 15 minutes, It goes from 100% to 68%.

After the second time I did that, after the overnight recharge, I immediately put it put the watch into “low power mode” and my battery seem to progress down more normally- been doing that for the week but today I did not do that and it went down to 68% again right after the overnight recharge.

looks like I just need to put it in low power mode until they get a new update.

Mine has gone from 72% at 7:30 am today to completely shutting off at 4:15 pm Before IOS 11 update only charge the watch once per day in the evening. This need attention now!
