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
