Apple Watch battery draining fast after watchOS 11 Update

Finding very heavy battery drain with this update. From 9am to 10am lost 10% battery. Usually at 7pm I would have 65-70% battery left. Sitting at 50% right now.

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

Clearly there is still a problem. My Series 6 is at iOS 11.2 (22S101), and battery "health" is at 93%--well above the point where Apple says it should be replaced. I periodically get a notice that optimized charging limits the charge to 80%, and sometimes after sitting on the charger overnight, it is at 80%. Other times it's at 100% or some level of charge between 80% and 100%. I'm guessing that at some point, charging is cut off by the watch, and at that point, the battery begins to discharge, since the watch is still turned on. Today, I slept later than usual, and when I put the watch on it was at 76%. After I spent some time looking up the iOS version and battery health, it was down to 67%. I have low power mode turned off.


I am convinced there is still something wonky with power management with the Apple watch operating system beginning with iOS version 11. My wife's Series 5 stopped updating with iOS version 10, and she has no problems with the battery charge, even though the health is down to 88%. I had planned to get her a new watch for Christmas (which she would pick out, of course), but the battery issue got in the way, and she selected a new camera instead. (Too bad. The camera cost 8-10 times as much as the watch would have!)


Merry Christmas, everyone!

I have the same issue. Watch (Apple Watch Ultra Gen 1) a week ago would last for ~1 1/2 days on a single charge. Now, even after removing all apps, notifications, etc., basically making it a dumb watch, it is draining in 5-6 hours. I purchased the watch just over a year ago.


At this price point, this is beyond unacceptable and will likely be the final straw for me on Apple Watch. I have been a faithful brand loyal customer for more than a decade and the upgrade degradation is just infuriating.


This is just after I committed to move from PC to Mac… what a roller coaster of customer adoration and disappointment.

I think it is absolutely ridiculous that we keep jumping through Apple hoops to make our devices functional again after these last product updates. These updates have thrown my phone, iPad and watch into limited functionality. Instead of acknowledging and apologizing for all the issues, issuing correction updates, or even warning people about them, they stonewalled. These updates were absolutely not fully tested before issuing. They could and should have issued them in smaller updates rather than trying to make a big splash in the tech world. They made a big splash alright with one huge belly flop.

I have done all the recommended procedures ( restarting and repairing the watch) to fix this problem but it seems it didn't fix it. After doing the restarting and repairing the watch I was at 85% from 95% battery power. In 3 minutes I went from 85% to 79% and all I did was sit. At this rate I will be at 0% in less than 2 hours. I want to know what apple is doing to resolve this problem. This had been going on far too long.

As helpful as your reply is trying to be, we’ve ALL waited, then unpaired. Then reset. Then manually updated. Then re-paired. Then waited again.


We’ve all done all the things many times and the problems with the battery persist. All Apple does is look the other way and say “oh no have you turned it off and turned it back on again?!? Did you clear the cache and cookies?”


SOMETHING is causing this issue. It’s not a fever dream. It doesn’t help that there are NO diagnostic tools we can access to find out what’s going on.


“What’s using battery the most” on the watch should be a standard application for watchOS. Nope.

You are absolutely correct. Apple tells us to jump through hoops a mess of hops to unpair the watch and iPhone. I am not sure this is a solution. Furthermore, they did something in their massive update that caused the issue. If they still don’t know what they did they need to find out and correct it. What would prevent them from doing it again and again in updates? Are they just going to tell us to jump through hoops more hoops? They cost wayyyyy too much for this irresponsible inconvenience.

These kind of replies that pretend Apple support is listening to us, but nicely trying to say that we’re the problem do not help.


This is not a I updated last night problem. This is an every single day and after repairing and repairing and repairing several times, this is an ongoing problem.


dont just regurgitate an easy answer. Its belittling. Do better apple.

I’ve recently tried turned off both options in live stacks (a fix I’ve seen for some on here) didn’t work for me.


on my s7 I’ve also tried mobile data off WiFi off. And battery still horrendously also noticed since the battthas gone thru 100’s more cycles I’m now at 79%battery health


I give up not buying a new battery for my stainless s7 if this battery drain continues and not buying a new one mate has a 8 and 9 and he has the same issue
