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.

Same here. I could easily go 2 days before needing to charge. Now needing to charge it every 2-3 hrs. Then it has to be restarted to even take a charge. I called apple, rep had no clue what to tell me then I went to my phone carrier, all he said was wait until a new update. So basically my watch is useless. I can’t stop every 2 hrs to charge it. As much as you pay for this and the cell service you’d think this wouldn’t be an issue.

I started the update, it paused saying that I needed to have my watch connected to the power, I connected it, watch was at 74%, right after the update was done, the sensor where the power is connected was a bit warm for over a min and then the power went down to 72% and from that moment it started to drain like crazy and two green lights came on for no reason, I have the orange button disabled so why the lights were on?

.

Three hours later the power went from 72 to 50% and ever since a full charge last only 6, 7 hours tops.

.

My phone is not updated to the 17.1 and nor will I update it.

I would say it’s 100% an issue caused by Apples update and unsufficient testing.

Looking at this thread it’s hard for me to believe that no Apple staff with an Apple Watch ran into the same issue.

For me it looks like a business decision - how many Watches are out there? How many third party apps might cause this issue? How many issues do we expect based on the number of installed third party apps?


And to be honest - taking such a decision is fine for me - otherwise every OS rollout would be stopped by a minority of issues and affected users.


But what really annoys me / makes me angry in this case is the lack of information of the Apple support and the lack of communication towards affected customers!


The customers themselves - for example in this group - had to analyze and to discover causes and workarounds for their problems caused by the OS update.


I took my own decision because of this behavior and - as stated before - switched from Apple watch to someone else, because for me this experience is not the way how I want to be treated as customer.


cheers

Sorry for the double/triple posts here, but accusing the 3rd party apps or app devs is not right, if they haven‘t updated their apps, but the OS was updated.


Btw: I haven‘t read any statement from Apple about possible issues with 3rd Party apps prior or after der WatchOS10 release.

Was there any news or thread, that shared information about updated OS features that 3rd party Devs where informed about and did not update? I haven‘t seen any.

I have an Apple Watch Ultra, and ever since the last update to 10.1, my watch drains from 100% to nothing in a matter of a few hours. And then when I got to charge it, whether it's a third party charger or an Apple charger that came with the watch, the watch doesn't actually charge. I have to either reset the watch or turn it off and back on to get the watch working again. This has been happening for a week or two now.


I thought maybe it had something to do with when I transferred everything over to the iPhone 15 Pro Max a couple weeks ago from my iPhone 12 Pro Max. But a phone hardware change should cause battery issue with the watch. The only other thing I can think of is the software update.


Now, today my wife put her watch on and in a matter of a few hours the watch drained down to nothing, also on iOS 10.1. Problem is I have it on the charger and it's not charging and I can't even get it to reset. This is a bit ridiculous considering how much Apple charges for everything. This might be the end of line with me and Apple.

Never had an issue with my Series 6 and downloaded the update 10.0.1 for it. Battery died within 3 hours after being fully charged. After the 4th day of noticing this I tried reporting it to customer service. They ran a diagnostic and said nothing was wrong with my iwatch. I said it started after the update was downloaded and they kept downplaying this. Stopped wearing my iwatch.

This article is what I was waiting for after downloading the 10.1 update twice I had to have my Apple Watch series 7 re-programed with apple which took 3 days each time to get it back from them. I am sticking with update version 10.0.1 until a fix for update 10.1 is released. Thank you for sharing the article I just wanted to know they are working on a fix for this problem.

Wife's iWatch after upgrade only gets a few hours of run time before it say's battery low. Prior to update battery would last all day. Can anybody confirm if you can remove the update or if you end up having to do a factor reset?


This is poor support via Apple, why didn't your CI/CD process not pick this up prior to pushing out the update, bloody joke Apple. If i didn't know better i'd say you have done this on purpose so force people down the route of buying new models!. If it worked before update then it should be fine after the update, sort your house out Apple.
