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

Yes I have ultra 1 and updated and samething. Use to get 48 hrs out of watch and now get less then 8 hrs plus getting no help!

Just spoke with apple customer support: and the only solutions are

• return the watch and ask for an OS downgrade to 10.02
• wait until a new upgrade is released

They recommended not using the watch in the interim period. 

I have asked that this case be escalated and made reference to other users (you!) having the same issue. The support has escalated this accordingly.

So no solution (yet), but at least flagged and hopefully not too long to wait. 

*** UPDATE

Interestingly the apple support removed my earlier post, stating the this was no place for developers discussion.

So let me be very clear: I installed the released 10.1 update which was pushed onto all devices - NOT a beta. Your own support referred to it as ‚beta‘ - however it clearly isn’t and this post absolutely belongs here.

I got series 6, and I just can't believe how it totally drained in an hour after the update. Just picked it off the charging puck this morning, and by the time I got to work, I got the 10% notification, 10 minutes later it was at 4%. I barely checked some settings and shut down.

Same issue here. Was fine until 10.1 Won’t hold a charge more than a few hours. Tried rebooting but the problem persists. Not sure a reset will fix it because it stays on 10.1. I shut off background app refresh (which I never had to do before.)

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.

This battery drain is ridiculous. I put on my watch this morning when it was at 100% battery. It has been 1.5 hours and I'm already down to 59%. I have the Series 6 and the battery drain has never been this bad with an update. Yesterday my watch just turned off mid-walk after I updated and it was fully charged.

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 went to the Genius Bar and they checked my watch and ended up sending in for repair. Just checked on the status and it states they couldn’t duplicate the issue and probably will be sending it back soon. Mine will not hold a charge longer than 6 hours and sometimes it get too hot charging and stops at about 79%.

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.

Went to the Genius Bar, all they would do is send it in to a depot.

of course, their SOP is to unlink the phone and watch, which purges the logs.

Apple certainly seems to have lost some of their magic.

I went to Apple Store and had the same experience. They said battery was 98%, so the problem was not battery. I said it happened immediately after I updated. They said I would have to wait for fix. Can’t do anything it drains so fast it’s useless. And I had to charge 7 times to get my stand ring closed on fitness.

Shocking drain on my series 7 since the update. Have gone from 100% charge to 5% in 3 hours.

Genius Bar not a lot of help. Said wait 48 hours for the update to finish “settling in”. Other than that wait for a software fix to be sent out. Nonsense! This has never happened before. Watch is now rendered useless….

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).
