Apple Watch Battery Drain Issues after Update

Ok I have had some success in fixing the battery drain on my Ultra 1st gen. iPhone 14 Pro Max (iOS 17.1) & Apple Watch Ultra (watchOS 10.1). Not sure which fixed it or if all played a part but here's what I did;

1. Unpaired the watch and set it up again restoring from backup, NOT an erase all option, an Unpairing.
2. Let it restore and chose to setup from backup then restarted the watch and my iPhone.
3. Removed ALL 3rd party apps from the watch including any watch face apps.
4. Deleted ALL modular watch faces I had in the watch app on the iPhone. I had one as my current watch face on the apple watch and when I deleted them all from the phone app I noticed it still had the modular face displayed on the watch even after several minutes. Upon looking into the watch faces on the watch itself all my modular faces were still there even though they had been deleted on the iPhone app.
5. Restarted the watch and iPhone together and once restarted the Modular faces were gone on the watch itself.
6. I temporarily used a default watch face to verify the battery was draining insanely fast. I used the Toy Story Toy Box one in default settings.
7. The watch wasn't draining very fast after an hour so I created a couple Modular Ultra faces the Watch App on iPhone and the watch is now draining much more slowly.

I still don't think it's back to where it was but at least it doesn't appear to be losing 90% battery in 6 hours. I hope this helps some people to get their watches working better and not being forced to put it into low power mode as some were suggesting.

ibe had the Same issues since updating to ios10.1 last night. Been playing with it all afternoon and think I’ve sorted it.

1. turn off location services
2. delete all 3rd party apps
3. hard reset watch
4. reboot and reinstall from last data save after 3rd party apps deleted
5. so far so good. Infact been on 73% for half an hour.

This is what I meant claudiu129,

If you click the lightning symbol while your watch is connected to the charger in the top left corner…

You can select charge to full now.

or like someone mentioned you do have the option to turn off optimized battery charging. I don’t have an issue with the battery draining faster like some of the others though.

I uninstalled MobyFace, all faces in the watch face que from the app, reset my watch 8, my iPhone 13pro to factory settings, logged back in on both and paired the watch and phone again. In 24 hours only used 54%. It was draining in 4 hours since the beta 10.1 10/12/2023 I installed. Guys, stop being mad at Apple because the third party app (which they warn you to use at your own risk) code has a bug with their update. It’s like buying an aftermarket piece for your car and getting mad at your car if the aftermarket piece messed your car up and voided the warranty. Apple doesn’t do updates to go along with apps code, it’s sends the update to the developers way before the public for their code to be ready for the update. MobyFace screwed this up, not Apple.

So this appears to be an issue with a 3rd Party app not actually 10.1, It was just caused the 3rd party app and the ios to not behave properly. Applde is not responsible for 3rd party apps behavior. I deleted the MobyFace App and the watch went back to normal operation. My wife has a Series 8 and it was doing the same, all I did for her was remove the MobyFace App and hers went back to normal operation and battery use.

Before

After : 100% Charge and Normal Battery behavior

Same here!!! Mine doesn’t even last the whole day at work. Apple needs to fix this.

Newer second gen Se same BS. Used to get a full day on my nightstand. Now I’m lucky to see 5 PM.

I am having the same issue. I charge my watch at night. I hardly use it during the day other than checking the time. And by 5:00 pm the battery is dead! This is terrible. No more updates for me!

We paid too much for our watches to have this ongoing issue. The latest update did not give me any more battery life. Is their a recall planned?

Hi

my watch this s series 9 and my os is 17.2

last night di charged my watch to 100%. And then And I immediately turned off my watch, in the morning I turned it on and it was 62%. The battery health is 100%, but it doesn't last a whole day recently.

My suggestion is to not update. The Genius Bar couldn’t help me and it seems Apple is silent

After update my battery life drains very fast within 3hrs and again when I try to charge it’s 109% in less than 30mins not sure hats going on everything was working well before this update.

Since the update my watch barely lasts 9 hours. It used to last part of the second day after charge. Please fix this update

How about checking the suggestions that worked instead of just complaining to a forum that probably has no control. Mine is much better after I used suggestions.

i

Mine is exactly the same issue
