Apple Watch Battery Draining suddenly after Software Update

This seems to work for me as well. My watch didn’t update to 10.4 - I remember initiating the update but it’s still 10.3.1. Disabled auto update and restarted twice and it seems to drain normally again. My wife’s watch and phone got updated so it seems the massive drop is avoided if the watch is also 10.4 - but then again it’s just one case. FWIW, mine is 15 Pro with series 6 but hers is 14 Pro with series 7.

My phone updated to 17.4.1 IOS Wednesday night and charged my watch like normal Thursday and after only 4 hours it was dead. I changed nothing about how I normally use my phone or my watch. Then on Friday I had to charge my watch 3 time and it was at 100% when I went to bed and dead before I even got up this morning. Apple please fix this. I can’t carry around a charger and battery pack everywhere!

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

It took awhile but I finally got the watch to update and that seems to have helped the battery drain. I toggled off background app refresh (based on the rec of another poster) and that seems to have fixed the problem with the watch update.

I´m having EXACTLY the same problem! - battery goes from fully charged to 0% in about 3 hours! - I can´t even update my Watch (7 series) because the update gets stuck on "preparing".

The watch is unusable until a fix comes along.

Very frustrating!

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.

This happened to me yesterday. Completely drained battery after 3 or 4 hours. I tried the software update on the phone which was problematic as it said it would take 3 days to download, but I left it overnight and installed the new watch update this morning. So far it seems to have resolved the issue

I had the same issue with my Apple Watch Ultra2 after the update. The update won’t install if your watch battery is below 50%. I had turn off the optimized battery charging feature on my watch so it would charge over 50% last night. The update installed and my watch is working fine now. It died 2X yesterday.

I too experienced this after the Software Update on my iPhone. However, I managed to update for Apple Watch. So far so good. I am monitoring my watch battery it doesn't look like it is draining that fast anymore.

I finally was able to get the latest Watch update done and so far, my watch is still going strong. It was a waste of time calling Apple and when I said that their phone lines were probably blowing up with people complaining about the same issue, she had no comment.

So, if you can get the update done, fingers-crossed, that should work. I unlocked the watch and put it on the charger even though it had been there all night. When I came back half an hour later, the update was done and so far, so good.

Okay. I fixed mine by 1) disconnecting bluetooth 2) clearing all background apps running on watch 3)putting it and my phone both on charger 4) downloading watch software update manually (which required turning bluetooth back on but they were both still on chargers) 5) letting the update happen.

Watch is now charging normally and retaining charge much better. I still think it's draining faster than it used to, but only barely (down 2% in an hour).

Same issue. I lose about 20% battery every hour, and it’s dead before lunch. Prior to that it lasted over a day.

This is for a series 9 I bought a couple months ago.

Even with AppleCarew they’re telling me it ‘passed diagnostics’ and so it’s not covered.

Hopefully there’s a software update coming soon that solves it.

I had the same problem everyone is talking about with my Apple Watch Ultra 2. It actually died twice yesterday after the update on my phone. The new update will only install on your watch if your watch battery is above 50%. I had to turn off the Optimized Battery Charging function in the watch app to charge my battery enough over night. The app installed on my watch overnight and no battery draining issues today.

After the update with Apple Watch, it has fixed the issue. Please update the watch as well. I did yesterday night at 8 PM (full 100%) battery and this morning it is 88%. Otherwise it would have gone to 0 after 4 hours.

updated the iPhone to 17.4.1 and Apple Watch suddenly started draining in say 4 hours.

updated the watch( charge must be above 50%) to 10.4 yet the problem persists.

apple engineers are not performing quality checks.
