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

Today Watch OS 10.1.1 is out. I'm d/l it now. Fingers crossed that this issue will be fixed!

Upgrade to 10.2 and then leave it on the charger for 48 hours.

Is this post helpful enough Apple? I'm on to you.

As Apple just removed my last post, I will try to be less snarky.

They told me to wait 24 hours as the software may be finishing internally on the watch.

So I am hoping for an update to the update so I can wear my watch again.

I have figured out using the watch in Airplane mode and the battery doesn't drain so fast. My watch would go from 100% to 80% in around 1hour then be dead by 9am. Today, I put it on airplane mode it last the day. Just put it on the charger at 45%

Have you tried deleting all 3rd party apps from the phone? That worked on my series 7. For me it seems the Moby face app was the issue.

I uninstalled Mobyface (and a few other apps) and the drain issue is much better today.

I deleted all the apps, uninstalled them, reset the device without backup, then installed them without backup and run Apple Watch apps no longer installed works better now battery rusted

I deleted everything from the watch without a backup and then installed no more apps and switched off the rest so it works again without using up a lot of battery.

see all the remedies in here. The vast majority of users find 10.2 has good battery life.

Same issue here. Ultra 2 paired to an iPhone 13 Pro, 10.1 / 17.1. Battery won't fully charge on a fast charger due to overheating. Have been able to nudge it the rest of the way toward 100 (at 98% as we speak) using an older first generation charger. Drops about 10-15% per hour of use, whereas it used to be less than 2%... yesterday.

My brand new Ultra 2 went from 2-2.5 days of battery before the update, to going from 100% to 20 percent in less than 5 hours.

It does charge and it does not overheat. This is NOT normal behaviour due to rebuild of caches or other such mumbo jumbo.

Reboots, and restores without backups make no difference (as others have allready reported), presumably going back to 10.0 might make a difference but that is not possible.

Hoping a fix comes quickly. For now, I put it in Energy saving mode, that seems to bypass whatever process is sucking up energy (though it is a somewhat crippled device now).

I have the same issue. I have to turn the watch on and off each time I charge, however the battery is draining super fast when it’s not charging. When I turn it and off before charging it charges super fast. So I would try that.

I found the fix! I couldn’t believe how fast my Apple Watch Ultra 2 battery was dying either. It went from 100% to 0% in a little over 5 hours. I usually use it heavily and still have 83% by the end of the night when I put it back on the charger. I upgraded mine to 10.2 and I have no more issues, my watch is back to normal, no battery issue and running smoothly! I’m so happy. I can’t say the words on here or this message will get deleted. But become a d******** and get the p***** b*** 10.2. Your watch will be back to normal and not useless on the 10.1 that is killing our batteries!!!

I have the same issue I called Apple support to inform them that it was an software issue after going thru the usual check list they finally agreed that it was a software issue and I would need to take it to Apple Store. After that I don’t want to damage the battery so I’m going to take it off the charger in hope that a fix will come out soon.
