Apple Watch Ultra battery draining while on charge after updating to OS 10.1

After I update my Apple Watch Ultra software 30mins ago the battery keeps draining while the watch is on charge. It was on 80% and while on charge with the green bolt sign showing it’s dropped to 76%


I’ve tried restarting my Apple Watch Ultra and iPhone 15pro but the battery percentage still drops on my Apple Watch Ultra while on charge.


my iPhone 15pro software is up to date too with ios 17.1.


how to fix this. Please advice

I had the same issue with my Ultra 2! I saw on another string that Mobyface was the culprit. Rang true to me because I have that 3rd party app. I uninstalled it from my phone and watch and my battery draining issue went away!!! Hope this helps.

I have a Series 6 as well. I contacted Apple Support as directed, and was told that I need to wait 72 hours for all the background apps to update(strong whiff of BS here). Since then, it has only gotten worse. When it is fully charged to 100%, the battery is dead within 3 hours. I put it on to charge last night at 10PM, and when I checked it again this afternoon, it had only charged to 65%. I'm going to put it away until they have a fix before the battery is ruined.


Apple, you need to FIX THIS NOW.

My Ultra series 1, froze for 30 mins couldn’t reboot. Finally it rebooted and froze 3 more times. I can’t believe this happened to me. I scheduled an Apple appointment for Sunday, my watch is draining so badly, it’s kinda a waste to wear. I am now afraid 😱 to update. Thanks 🍏 I know there gonna make me reset and unpair my watch from phone

So after updating to 10.1 my battery life on both my Ultra and Series 5 plummeted. My Series 5 went from 100% charge to 5% in 3 hours. My Ultra would not charge fully Friday, and Saturday I tried a hard restart and it’s became a brick. Stuck at the Apple logo… I have tried a hard restart several times and it just goes back to the logo. I have tried charging for a few hours and hard restart and same result.

This is wild. I had a 5+ year-old Apple Watch SE that worked fine (despite having a busted side button). Like a good little Apple customer, I keep my software updated and the 10.1 update murdered the poor thing. I figured after five years, it just gave up the ghost. I went up to the Apple store and bought a brand new Ultra 2 and the thing dies after a couple hours. I've shut everything off. It's essentially a pretty brick on my wrist that drains 15% just by walking a mile.


I really hope they rush a patch out asap. This is very disappointing. The reason I stick with Apple is because everything "just works".

I have upgraded to the latest version of Watch OS (10.1.1) after this Watch battery fiasco with hopes that it would resolve the battery drain issue a lot of us have experienced. There is good news & bad news!

The good news is that it has helped somewhat lengthen the time between needing charging.

The bad news is that my charge still only lasts about 14 hrs. before having to recharge it. Not even a full day! Prior to the upgrade to 10.1 it would last close to a full day. So Apple has not really restored the battery to where it was before this problem began. I can only believe this problem that happened after the upgrade, caused the battery to be damaged.

This is not ok!😤
