Apple Watch Battery Draining suddenly after Software Update

You making the assumption that if the symptoms are similar the cause must be the same and that’s a false assumption.

I go to the Dr with a shoulder pain, my Dr. runs tests and determines its arthritis. Another man goes to the doctor with same symptoms and he gets diagnosed with a torn rotator cuff.

Until you run the test for the most common cause, you don’t know if it’s the update or the iPhone and/or watch have syncing issues, processor loop issues, bad 3rd party software, complication issues or what exactly.

My experience as a former Apple Store manager qualifies me to write the above. I’ve helped and solved hundreds, if not thousands, of customer’s issue with the simple process above.

Same issue Apple Watch Series 8

100% to 0 in 5 hours twice

My wife, SE2 same issue

I’ve done the same (updated via my watch while it was on charge). Took a couple of hours to update… will see if that fixes the battery issue 🤞🏻🤞🏻

I didn't start having this problem until I got both updates on my devices.....Both are current and my watch just lost 15% just sitting here.....

I updated phone and watch last night and now my watch is back to normal. I really thought it was just me until I saw this thread.

An Apple support agent today told me that complaints about Watch battery drain are the major reason why people are calling in to complain. It is a "known issue." Hallelujah.

Same issue - my watch lost 80% charge while i was sleeping.

Just recharged it and it has lost 13% of charge in less than an hour, just by wearing it, literally no use besides wearing it.

I can´t update my watch it is stuck in the preparing mode, has been for hours now.

Fix it now

Same issue. Watch was 100% at 7am, completely dead by 11.30am. Was chatting to Apple support to no avail. I explained it was only occurring after the update. Was told there was nothing wrong and asked was I suggesting there was a correlation between the update and the issue.

Well thanks for the solidarity, everyone. I wear my watch all day and night with a quick charge here and there with no issue. I was alerted early evening it needed to be charged so got it back up to 100% before bed because I use it as my alarm. Well you can imagine my surprise when I woke up an hour late to a dead watch 6 hours later. Got it charged again this morning to 100 and it’s already down 15% in an hour!!

I also recently got the iOS update. Watch update is stuck on “preparing”

what gives??

Mine is doing the same. The last two night I went to bed with it charged and woke up and it’s dead. How do I go back to a previous update? I go on vacation soon and can’t have this dying all the time.

We would update our watches if we could!!

My watch was fully charged overnight, less than 10% after 4 hours wear this morning, recharged to about 75% and back to below 10% less than 2 hours later. iPhone 15 updated to iOS 17.4.1 overnight. Tried to update Apple Watch SE to iOS 10.4 and it is stuck at 60%.

Come on Apple - sort it out!

Mine won’t update. I have tried multiple times. Did hard restart on both the watch and my phone, didn’t help. Got on Apple chat support, completely unpaired and re-paired my watch, didn’t fix it. I have a support call scheduled and I am not optimistic it will help.

I’m having the same issue and watch won’t update to 10.4 - gets stuck at “preparing”. Followed all the advice from Apple chat support. Was told the battery is functioning just fine and that this can happen after an update - what?!? This has never happened after an iOS update before. Running a 10k tomorrow and hoping my watch will live through it.

Me too. iPhone 11 Pro Max updated last night - today Apple Watch 7 battery drained from 100% to dead in 5-6 hours. Not much chance of me closing any rings - or being woken up by my alarm in the morning.

Joining the many who got the latest iPhone update last night 4/11/2024 and now my Apple watch battery doesn't even last a day!! I've had the watch for a year and it always lasted a full two days before it needed charging and now it barely gets by on a few hours. WTH??? Certainly not buying a new watch!
