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.

Terrible battery drain after updating watchOS 11 on apple watch series 7. The apple watch goes from 100% to 84% in less than 1 hours. In 8 hours, the apple watch is running out of charge.  Worst of all, this is using it as normal watch, not playing music, not tracking any sports or activity from workout app, just putting in my wrist to use it as a normal watch.

Nothing I tired worked. Shutdown and restarted both phone and watch many times, since unpairing and reinstalling software on the watch. Only thing that helped reduce the drain was shutting off live activities. I never had the always on display on, also have reduce motion on. Other than that, I have to charge twice a day or I’ll run out of battery during the night or in the middle of the day.

I would like to add to my comment as well. I did buy a Series 10 Black 45mm watch. The battery life is better than the other watches right now. However, Apple states 18 hours of battery life. On the new one, more like 12-14 hours. Defiantly a software issue. It also has been almost 3 weeks. Since IOS 18 and Watch OS 11 has come out. Apple needs to stop focusing on IOS 18.1 and the AI, and focus on the existing bug issue at hand!!!!

Yeah, I feel your pain. I have the following settings, Always on Display - off, Live Activities - off, Siri - off, Reduce Motion - On, Display Brightness @50%, Wake on Crown Up - Off, Auto Launch Activities - Off, Background App Refresh - On (but only apps that I need), Haptics On (because I press buttons as I move around and want to notice it). Other than that it’s charge twice a day.

Exactly. I’ve tried everything. Even unpaired twice. Zero improvement. I used to be able to do 3-4 walking exercises for 30-60 mins at a time and still wake up with 35-40% battery. The other day I wanted to see how far I could take it without charging twice in a day. I woke up with 5% battery. Battery health on the Watch is 87%. Other complaint I have are the updates to Timers and Weather apps also stink. They went backwards on the update and did not improve it.

So I have been working with Apple directly about the battery draining issue along with a backup issue. The backup issue is that the watches have not been backing up since the beginning of iOS 17. Appears that when you go to settings>iphone storage> and look for the watch app, your backup are showing old ones and not updated backups. This has been reported to an engineer at Apple now. However still leaves the battery draining issue. I finally unpaired 4 of my Apple Watches series 6,7,10, and ultra. All have returned to normal battery cycles. However, the olds of you getting a recent backup may be low per everyone reading this. After unpairing and setting up the watch again backups and battery cycles return to normal. Not for sure if the issue has to do with multiple watches connected to a device which I have 5 which is the max per device. Either way this a bad bug!!! Not for sure if this will ever get resolved. After reading several bugs, the battery draining issue has been present since July and 1st of August in the betas and never got fixed.


in conclusion my recommendation for everyone have issues with the battery is to unpair the (I) set it up as a new watch, but the restore from backup should work too. Hope this helps everyone!!! Good Day Mate!!!

Mine lasts for 6 hours. I already tried a watch and phone reset multiple times. In addition, the battery health dropped from 100 to 83% during this time. This means that I will need to replace my battery once it reaches 80% if Apple doesn’t address this issue.


Today, my watch also wouldn’t stop beeping, asking me to power it off, contact emergency services (SOS) or cancel. I would cancel or power it off, and it just keeps alerting me with the same prompt.


I did a phone reset and it happened again during the reset. I had to keep trying to reset it in-between the erroneous alerts. I have yet to see if this reset fixed anything.
