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

Not sure this is Apples fault. The solution seems to be third part apps. Especially, Moby Face. Developers should update their apps. With that said, any app that’s killing the watches like this Apple should pull it out of the store until it’s updated.

Update! I deleted the MOBYFOX app last night from my iPhone and watch. Left it charging over night. Took it off the charger at 5:55am at 100 percent. It is currently 01:06pm PST time, and my watch is at a charge of 82 percent. Full brightness on, cellular is on and connected, WiFi is one, and always on display is on as well.

So this problem started on my series 7 and then I went to the Apple Store and ended up buying a series 9 since my series 7 had a good trade in value. After reading another discussion post about this issue it seems as though the best thing to do is (if you have it installed) to delete the MobyFace app as it has fixed the problem for me so far. If you like the faces the app provides you can save the photos to your phone and use the photo face for these instead

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.

Moby Face isn't the issue. I didn't have Moby Face installed, same issues, 16 hours of headaches this finally worked.

Successful Steps to follow -

Watch won't charge - Probably overheating, stuck at like 40%. Remove from charger, place in cool place (Fridge worked for me). After that put on charger to get it charging again.

On iPhone watch app - remove 3rd party apps that you don't use. This does two things, it forces your watch to communicate with your phone and removes apps that may be an issue. After doing this my diagnostic logs went from 3 pages to 1 single item.

Restart both the Phone and the Watch - may not be necessary but it's always safe to do this step.

Hope that helps.

It’s probably a bunch of apps. Most of us found it to be Mobey but that doesn’t mean there’s not some other apps misbehaving. I’d just remove the apps from the watch and see what happens. If it goes back to normal then one of those apps are bad.

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…

I've got a Series 9 watch and did the update Saturday night, since then, it's not fully charging, drains battery veryquickly and overheats at charging point, tried different charges, reset it, and also removed the Optimise Charge limit function, and nothing still the doing the same. I had a chat with someone in support and now I've got a booking to take the watch to a store. Its' just 1 month old!!

I saw in other comments to delete all third party apps on the watch and it should fix it. My watch was going from 100 % to 0% in approximately two hours and that was with battery saver on at 100 %. I deleted all the third party apps and restarted my watch. It is now dropping about a percent every forty minutes or so, which is what it normally was at before the update. I hope this helps, I was at my wits end trying to fix this issue.

I can't delete any apps from my watch or phone, I can take them off the phone to the library, but the delete line doesn't show up. on the watch, they just shake. you can't slide the button off on the phone and nothing shows up on the watch in the storage. I've tried shutting down, erasing, and re-pairing with the phone, nothing works.

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%

Update, I unpaired my watch and paired again, removed all the apps in the phone including the MobyFace one and from my watch and seems to have sort it so far and it’s back to normal. I’ll monitor it in the next few days.

Same here! Mine used to last for 3-4 days on one charge. Not only is it dying quick it is also taking forever to charge. This morning after being on the charger all night for 8 hours it was only at 70%.. Today 5 hours later it is at 6%..

I upgraded my Watch Series 6 to Watch OS 10.1. It also drops the battery charge extremely fast. Have had to put it back on the charger 3-4 times a day to keep it running through the day since updating.

Hope it is fixed soon as this is ridiculous.

I was having the same issue. I called apple support and zero help from a regular representative. Told me to return the watch. I called AT&T and they said since it’s a warranty issue, I had to go through apple. AT&T connected me with a higher apple representative. This person asked me to type moby face into my search on my phone. It brought up an app that I never installed. It was something with photography. He had me delete it off my phone and check it was off my watch. Since doing that, my watch is not draining any more. He said he has had several fixes with doing that. Hope this helps cause I was about done with apple.
