Apple Watch Battery Draining suddenly after Software Update

It took 4 hrs for mine to drain today. Just awful. Upgraded to 17.4.1 yesterday. Seems to be taking forever to charge now too, but maybe it is because I am impatient and need to go somewhere. Need a patch apple.

Updated to 17.4.1 last night. Watch at 100% when woke up. By late morning was almost dead. I can normally go all day with workouts and all the regular activities and still have battery life. This is def linked to update. Watch iOS to 10.1 also stuck in “preparing”.

SAME!!! All of this. Watch randomly dying quickly. Stuck on software update for watch. I completely wiped my watch today and restored as new and is still having the same issue so it’s definitely related to the iPhone update. Hoping it’s fixed asap bc I use my watch all day every day.

Me too my phone updated at night. I gabes my phone and watch at 6:30am. By 11:00 am my watch was at 3% luckily I had my charger so I put it to charge. It charged up to 80% and around 12:45 I grabbed it and put it back on my wrist. At 3:30 it was again at 10%. Whats up. And I think my iphone is also draining faster. Its 5:45pm right now and usually i have 40% left and today its at 15%. Same usage as always.

Called apple two times today and even went to the genius bar to understand what was going on. No one could help and they pretend it can’t be happening after an update on the phone. They tried to tell me that they had to fix my watch even if there was nothing wrong with the watch from diagnosis. Very disappointed with apple :(

I followed these steps but couldn't find a way to delete the update on the watch - however, after going through the prior steps, I installed the update successfully and now my battery life is back to normal

My ultra 2 is less than a month old and I could NOT figure out why my watch that I normally can go almost 3 days without charging it, was dead by 11 am at work yesterday?! Charged it (took forever) and the charge only lasted 4 hours. Im happy and sad that I’m not the only one. Did the workaround and I pulled my watch off the charger at 7 am, ran 10 miles and it’s at 78%. Not back to normal, but definitely a step in the right direction.

same issue here I’ve had my Apple Watch Ultra for almost 8 months and have never ever run it out of charge in a day. First day I got the new update set up on my phone. My watch burned through 92% in less than eight hours. I have restarted both devices and it has seemed to improve things a little bit, but I’m still burning through 40 to 60% of my battery consistently now on a daily basis. Prior to the update, I was able to get almost 3 days between charges.

They are not. Apple doesn't read here in this user-to-user forum for feedback or suggestions. You can, however, let them know your concerns here:

I too, am experiencing the same thing, however, not to the same level that I see above. My Apple Watch SE is draining about 25 to 30% overnight whereas before it was less than 10%. Just as above it has been since the iPhone update. I was able to successfully update my watch to 10.4 tonight, even though it took an inordinate amount of time to “prepare” the update. I am charging my watch full before I go to bed so we will see you in the morning if this helps.

I have been having the same issue with battery draining much faster than before. I had difficulty updating my watch, but after unpairing and resetting it, then re-pairing it, the update finally went through. I immediately started noticing that my battery life was terrible. I typically charge my watch over night, but since the update my battery has been draining crazy fast. This morning I put my watch on at 5:45 am, and by 8:30 am I was down to 10% battery life.

I have the same issue. New UW2 drains 1% every two minutes. iPhone and UW2 software are up to date. Tried unpairing and re-pairing. The watch is literally useless and Apple support cannot find an issue on their end.

Truly unacceptable...

Has anybody found a solution for this, other than erasing content/repairing? Those don't work for me, I have tried 10x, but any watch I am pairing to my iphone drains drastically. I had faith in 17.5.1 update from yesterday, as they wrote they have fixed several important bugs, but I see no change.

Those who STILL face this issue on 21.05.2024 or afterwards, can you please check your phone's and watch's storage? Isn't the "other"/system data section very big?

@Kika_235 Are you using the same icloud account on your new phone? I am just curios, becase this is exactly happening to me as well, but for me on iphone 13 pro. I have bought 2 new watches as well to test with them, same happens with all of them. Doesn't hsppen, when the watches are paired to some other phones, we tried. Your example shows that the issue is on the phone somehow and not with the icloud then if you use the same account.

Updates 10.5 and 10.4 each caused battery drain on series 9 watch bought in January. Restart solved problem with 10.4 but with 10.5, problem persists. I have almost 30gb of music on the watch so I'm reluctant to unpair and return it to factory settings. It took 4 days to load everything in the first place - so incredibly slow. Advice like turn off always on, lower brightness, turn off background app refresh etc negate the reasons I bought it in the first place. If every update means I can't use lots of its functions, what is the point? Apple really needs to sort this out. It is beyond frustrating and annoying.
