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

I reset mine and set it up as new and disabled third party apps. It’s ok now.

Update: Removed all third-party apps and updated to 10.2. This appears to have resolved the issue for me.

Please look over all the responses. People have had a fix to the issue…

1. remove MobyFace
2. Reset as new

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.

So, in my case, I did a factory reset of my Series 7. Along with that, I made sure no third-party apps installed (if some installed, I promptly uninstalled them). So far, I'm having no battery drain issues. 🙂 👍🏻 ⌚️

Short story

2 watches series 7 & 9

Both updated to 10.1

Both dying around 3 hours from 100%

Tried restore. Didn’t help

Spoke with Apple technician via phone recommended deleting all third party apps.

Success 2% drain in 45 minutes.

I’ve been having problems for last 2 days since the 10.1 update, was only holding charge for 3 hours at best and I literally turned everything off to see if it helped which it didn’t, I’ve seen a post about the mobyfox app and if u turn it off it might work, well it has!!! My battery was at 77% when on dropped to 65% within 30mins as soon as I switched it off it’s stopped draining it’s been about 1h30m and I’m at 63% hope this helps someone else

I am having the same issue and started (again) for solutions and ran across a thread that might have a (temporary) solution until a fix is released. They were saying deleting 3rd party apps, particularly MobyFace, clears it up. I'm trying it now.

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!!!

Not sure if this will help anyone or if this will even work for you, but you may want to give it a try.

1st I uninstalled all the apps on the watch from the app.

2nd I placed the watch in Low Power mode.

3rd I lowered the brightness down to its lowest setting

4th I removed all of my watch faces except for 1

5th I turned the WIFI and the Bluetooth off and then on in the watch settings

6th I Shut down the watch from the watch settings and then restart

7th I placed the watch on the charger

The watch was cycling between 29% and 31% going up and down for about 5-10 minutes. After that I noticed the charge seemed to stablize and it continued to increase all the way to 100%. I have taken it off the charger and it seems to be holding at 100%for the past hour. Now I dont know what exactly may have been the deciding factor as to what fixed the issue but it seems to be working so far. My next thing to test is to see if it will stay stable after I turn the brightness back up and if I decide to reinstall some apps.

Hope this helps anyone! Spread the word if it does!

Indeed. The only fix that worked for me was installing the b3ta 10.2 Look how to enroll in it and you’ll be able to see it in your update list after that. Been back to normal for the last 3h, barely drained 2%

After trying the unpair route several times with no improvement, I turned off location services on my phone. That seems to have returned my 1 year old Ultra to performing normally. Clearly not a long term solution…

If you upgrade to 10.2 and the battery is still causing a problem, you need to leave it on the charger for a long time to fully undo whatever they did to make you put it on the charger in the first place. Mine started draining FASTER after going to 10.2, but then after about 48 hours on the charger it's back to normal now.

Thank you arsonist, for kind of putting out the fire.

If you have the MobyFace app delete it. I did and it finally has kept a charge on the Apple Watch 9

I saw on a different thread to uninstall the mobyface app if it’s installed. I did that and my watch is working better. Not sure if it’s back to normal yet but it lasted the night so far.
