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.

The discount towards a trade is only $115.00. And they told me I could not trade it like that. I am very sad 😞 This watch has a huge sentimental value to me and they just don’t care. They are blaming me just like when the lost all my mother’s message to me on their cloud that I pay for it. I will never hear my mother again. They say I was supposed to save it somewhere else too. In other words they told me to not trust their cloud.

Did you return one already and got another one with the same problem? 😱


If you can return and don’t have to pay for it I would do so. Wait a couple of months and try again.


My watch is incredibly hot even in my wrist! I know it has been damaged but they offer little help because they blame me for doing the update. They keep saying that it is a beta and that I downloaded it at my own risk. Out of 6 technicians I talked today only one told me it was not beta but the download was probably corrupted and he offered me a refurbished one if I gave a deposit of $350.00.


I am going to wait and buy a new one but not now. The new ones are having problems too.

Why still staying with Apple when their updates break the watch and the support and the company does not really care about it.

(I heard or read nothing about an official communication on this topic from apple - and this issue exists since watchOS 10.0.1)


I switched to Garmin and everything works fine for me: my data is now in Garmin Connect instead of Apple Health - just another app for me. I could continue my journey on being reminded to do sport, measuring my sport activities and losing weight.

My broken Apple Watch is now waiting, until this issue is fixed and will then be used by my wife or son (Here's another hurdle built in by Apple: You cannot connect an Apple Watch S4 with watchOS 10.0.1 to an Apple iPhone 6, because the iPhone would not get an iOS 17 update ... customer and environment unfriendly !!!)


It's time for a change.

My series 9 watch only charged to 78% because of temperature issues. I went to bed at 9:30, and took it off the charger without a full charge. I received a low battery message that it was at 5% over an hour ago, and I just woke up at 3:45 AM. I haven’t even made a full leasing payment to my cell provider for this yet. But I’m done. I am not committing myself to stand by this product anymore. Once my cell phone is paid off, I’m cutting ties to Apple all together. This is terrible. Yeah, I’m done.

ios10.1 Watch update - My watch used to charge in 30mins, now after 3hrs is only 50%. The full charge only lasted 4hours before low battery warning has come up. Previously would last 2-3 days.

iOS 17.1 iPhone update - same as the watch. Battery is draining quickly. Have had to recharge is three times during the day when I would never have to charge it during the day - only used to charge it at night.

Series 8, less than a year old. Ever since 10.1 beta, I’ve gone from 34 hours a charge to 4 hours. I’ve cleared and reset the iPhone 13pro, watch8 and still having same battery issues. I can’t wear my $400 watch a whole day working now. I have to charge it at lunch. This is some third world company failure. I have on me and in my home with MacBooks, HomePods, iPads, watches and phones over $3K worth of great hardware. Stop rushing this ****** software out and be as dedicated to me as I am to you Apple. We need a fix yesterday!

I’ve got the exact same issue and it doesn’t make me feel better seeing all these people impacted.


Is anyone from apple going to provide an answer for a solution through this forum?


I already tried all the tips about battery draining and even switched off background apps refresh, but the battery is draining excessively fast, about 5 hours, and before the update it was about 24 hours.
