Apple Watch Battery Drain Issues after Update

Since updating to WatchOS 10.0.1, the watch battery charges only to 80% overnight and the battery drains more quickly than before the update. I also updated my iPhone 14 pro to iOS 17 around the same time. Would this impact the watch battery?

As many here I was affected by the constant battery drain of approx. 5% per hour and I think I found what was causing this for me.

When I checked the Watch App on my phone ==> General ==> About it showed that it synced 15 photos even though I have not selected any photos or albums to sync.

Opening the photos app on the watch confirmed that and showed that there are no photos on the watch.

I then selected an album with one picture to sync and the photo count went up to 16. Next I created a photo watch face and set it to dynamic and suddenly the watch showed random pictures that I never selected to sync. I searched for these photos on my iPhone and deleted them from there until the watch only showed 1 picture being synced, which was the one from the album. I then changed the watch face back from dynamic to album and left the face on the watch.

I did this on Tuesday. Yesterday, on Wednesday my watch was at 37% after wearing it without additional charging for almost 17 hours. Usually it would have been dead after 14 hours max. Today I took the watch off the charger at 7:30, at 8:41 it jumped to 99% where it would have been at 94% or even less before and now at 12:30 it is still at 87% which is 2.6%/hour.

I think the constant photo sync would be a good explanation for this issue as the watch would constantly download new pictured from the phone and would index them. In addition to that it would also explain why not everyone is affected by this since this would not apply to people having their photo sync configured to sync specific albums rather than the watch syncing random photos when nothing is selected for the photo sync. And it would also explain why resetting the watch doesn't help to fix this issue since the watch would start randomly syncing photos again after the reset.

Might be worth to check/try for others.

When will Apple sort this out. My apple watch series 9 has been inoperable for two weeks now. I The update process takes forever and then it gets stuck on preparing. So i cant update to 10.1.1 which is supposed to fix these problems that apple has bestowed on me.


Battery is draining in 3 hours from full charge on the wrist and 5hrs off my wrist.

Totally not true. I never had a MobyFace on my watch and have experienced the battery draining issue, as have others. I called Apple support for an issue with my MacBook Pro and asked when the update for the Apple Watch was coming out for the battery issue and she had the nerve to say there is no issue, Apple doesn't know anything about that, it's a hardware problem. WOW!! I told her to take a look at the pages of posts on this site to educate herself!

Still having issues. The 10.1.1 didn’t fix anything.


Don’t have 3rd party app that people are blaming.


Having to charge watch twice daily, having to charge it to 100% daily was enough of a hassle but this is too much.


I didn’t get a smart watch for it to spend approximately 2 hours charging per day. I don’t have a desk job and charging it in the work van is a joke.

I dono what happened to Apple team- previously they were responding too fast and problems were easy to be fixed , a drop on battery life up to 50% is a disaster. Do something about it - even this IOS 10.1.1 doesn't make a big difference . just do your %$^$^ job and fix it instead of going on youtube waiting for a lunatic to tell us unpair the watch and dip it in green water then read some VODO stuff and it will get back to normal /. So boring and frustrating from Apple
