Apple Watch Battery Draining suddenly after Software Update

My iPhone updated to IOS 17.4.1 last night and all of a sudden my Apple Watch is losing charge today after barely 4hours. I haven’t used it any differently to usual, haven’t actually updated the watch at all but am at a loss on what to do now. I’d love to roll back the IOS update if that’s possible and the culprit but surely Apple has some accountability to sort out the consequences of their software updates? All and any help is appreciated

Apple Watch Series 7, watchOS 10

I had exactly this issue yesterday and found a fix! I woke up with my phone having automatically updated to iOS 17.4.1 and then my watch battery started draining approx 4 times faster than usual. Tried to update watch OS to 10.4 and it kept getting stuck on “preparing”.


I read online that issue could be fixed by updating your iPhone through iTunes on Mac/PC. I did this even though my phone said it was running iOS 17.4.1-it still installed an update on my phone once connected to iTunes. Then I update my Apple Watch, it took around 40 minutes so just leave it do its thing. Battery drain is fixed!! Hope this helps

I am having the same issue. Updated 2 days ago and now the battery drains quickly. Normally, I charge my watch around 11pm at night. At that point it has been on my arm since 8 to 8:30 am and the battery is between 55-58 percent. Last night at 9pm it warned me it was at 10 percent. Has NEVER done that. Nothing was different. Watching it today and it is draining much faster than it did before update. It is definitely the update!! Apple needs to fix this now!!!! These things cost too much for them to ruin our batteries like that!!

I really hope someone from Apple is reading all these comments.


After having to recharge my phone three times per day I deleted the update (10.4) from my watch and disabled automatic updates so am still running on 10.3.1, despite updating my phone to 17.4.1. Many people have not been so lucky.


Come on, Apple - give us a new update to fix the problem.

I am echoing everyone else, it seems. This problem of a fast dying battery started about a week ago, and seems to be getting worse. I did a reboot and that didn't help at all. I have a friend that is having the same problem. I had another update at 4:11am so I guess we will see if that fixes it? I am very concerned that it appears Apple is telling people there is nothing wrong when there clearly IS?

I am having the same problem with the Apple Watch update 10.4 stalling at 2/3 through. I have tried deleting & starting over but to no avail. I am also having the problem of the battery drain on my watch. I am trying the work around that iTMOM608 suggested but haven’t tried starting back to updating the iOS. 10.4. I hope Apple sees these complaints & does something about them! If anyone finds a solution please post it & let me know.

I’m also having the same issue.

The battery doesn’t last a full day (morning to night) on the series 5.

Before, the battery was reaching around 40% at the end of the day.

The issue started after the watchOS 10.4 update, and it’s still there after the watchOS 10.5 update, the update didn’t solve the issue.

I changed the iPhone that’s paired with the watch, that also didn’t solve the issue.

Me too!! Ever since I upgraded to a new iPhone 15 Pro the other day my Series 7 watch has been dying in a couple of hours. It normally lasts an entire day. Both phone and watch have most recent software updates. The battery even depletes when it’s charging. It was fine when paired to my 13 pro, also on the current iOS, but ever since getting the 15 my watch is basically useless.


Apple needs to fix this asap. There’s no reason a 2 year old $800 watch should die that fast.
