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.

I’ve seen people posting about eliminating third party faces like MobyFace and Facer. I happen to have a year long subscription to Facer. Why should we have to compromise with Apple about how we use or customize our watches when I have had my series 7 and used both these third party apps for better than 2 years without incident? Apple made promises about the increased functionality in their new hardware and software releases but we have to compromise how we were choosing to use our devices because their garbage software updates no longer support it? I am the customer who trusted their propaganda! If they can’t give me the functionality they promised, they can kiss my *** if they think I’m going to bend over backwards to keep their inferior product. They owe me a quality product; I owe them nothing, certainly not extreme loyalty when they’ve broken faith with me!

I didn’t go to any website and didn’t sign up for anything. I just updated from settings > software update and bum 💥 yet 5 of the six technicians fro Apple, and even the record before I tamed to them told me I had a beta software. One, a senior one told me that he didn’t know what kind of software I had but he told me that I wouldn’t get beta if I didn’t signed up for it. AND I DID NOT.

You are entitled to your opinion and I fully respect that but if you buy a app at the App Store you should trust that Apple aproves it.


I create videos for non profit organizations and also for individuals that can afford to pay a professional to make video of their weddings, graduation, vacation or wedding anniversary. I do it for free I just request a small donation to 3 of the foundations and charity organization that I support. So I have many software that is not sold on the Apple Store because just iMovie and Final Cut Pro is not enough and I can’t afford Adobe. When I download these apps I know the risk and I also know how to fully uninstall them (not just take to the trash, that lives tones of things behind). I am aware of the risk and I am pretty go in dealing with it. But when you buy from the Apple Store? These apps are approved by apple and I am sure they make a commission on it therefore they are responsible.

Past two days, after update, same issue.

I do, however, get to 100% charge - not sure about the 80% charge mentioned by folks below.

Used to get 24+ hours, easily, on my V7 Watch. Now I can almost watch the battery drain.

Charged before bed last night - woke up 4a, not working/drained, put on charger. Fully charged at 8a 100%, currently 9:30 and already down to 73%.
