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 am also experiencing the same issues. I have the ultra 1 (iPhone 13 pro max), less than a year old and updated (not beta) to the new version. The battery drain is incredible. Less than 8 hours and I'm almost at 0. I am not experiencing overheating from the watch and it is charging, but does take most of the night. Went to the gym for one hour and lost 20% of charge. Apple needs to fix this.

I have the SE(2023). It's about a month old. I updated my Apple Watch iOS this morning. After the update, it immediately became buggy. It responded slowly. It drained the battery in less than 2 hours. It is taking a very long time to recharge. It "bricks" and does not respond to taps. I have restarted it twice. I have been on with customer support. They suggested I unpair it. It took about two minutes, and in that time the charge went from 35% to zero. Now they want me to take it in for repairs. Please just fix the bug and send out a patch, Apple!

So, is this how software is supposed to work? Like a new engine that needs to be “smoothed”? Really? Can anyone PLEASE explain this request to wait 24 hours? I have received the very same answer when I told them my M1 iPad 5th gen was outperformed by my iPad 3rd gen: “give it a day or so and it will adjust itself”. Well, I never knew the conclusion, as I sold the older one…
