Battery Draining in 30 Min After 10.1 Update

Updated to watchOS 10.1 last night. Apple Watch Series 4 had 82% charge. 6 AM, battery dead. Charged for 3 hours, 100% at 9 AM, back to 6% by 12 noon! 100% charge used to last at least a whole day, sometimes longer. Now, won’t even last more than 3 hours!

My watch was at 100% this morning at 5:30am and hit 10% at 9am. I put it on the charger and figured it would be fine, but it died again an hour later. Now I'm watching it, on the charger, losing battery (went from 15% to 12% just now). The only thing I did was update to 10.1 this morning.

Hopefully Apple figures this out and gets it fixed ASAP....

Same here.

I've got a series 6 and everything was fine until 10.1 now the battery drains in hours and the Oxygen monitor complication doesn't show on the watch face even though it activates when you press on it's assigned position.

I've rebooted the watch and phone (15 Pro), unpaired and re-paired the watch and set the weather app to London rather than using geo-location and nothing makes a difference.

The watch is essentially useless at the minute

I’ve had the same issue, I’ve appeared to have gained back power consumption stability by removing all third party apps from the watch (series 9) - of course this is not a long term solution, I’ll start to add back the apps I need first to see if I can determine if one of them was responsible for the overheating and battery drain.

Just an update: I took my watch to the Apple Store and an Apple Genius ran diagnostics and said the battery was okay, so it must be a software issue and that, since it just started malfunctioning, it must be something new and, therefore, easier to get rid of with a reset. Further, he said that, if this procedure did not work, it would require a more extensive investigation into the software, not detailing exactly what that would entail. He then proceeded to reset my Apple Watch Series 4 by first unpairing it, then resetting it, then re-pairing it to my iPhone 14 with iOS 17.1. Well, after all that, and after several days and more recharges, my Apple Watch can now go from 100% to 18% in FIVE hours instead of 3 hours, so maybe that's "progress"? And, at least I now know it is NOT a battery issue.

Other posts have suggested removing third-party apps, like watch faces, but I never had any of those, so I guess I'm going to try and revert the OS back to 10.0, which was working fine until I updated to 10.1.

I use my watch a lot, and for the $400+ it cost, it shouldn't be a mere piece of jewelry.

Btw, I had accidentally made a service appointment at Best Buy for this issue and, according the their Geek Squad "Apple guy," their policy is to replace the watch for battery and screen issues - at a cost of about $250 for a Series 4!

I simply removed MobyFace from the watch and now my battery lasts for more than 18 hours which is great. I saw an update over the weekend to MobyFace on the iPhone but I didn’t take it since I figured it would install it on the watch again. Not sure if it would address the problem or not. Has anyone tried reinstalling MobyFace to see if the problem comes back?

After the 10.1 update my watch won’t charge, and when it does it overheats, and the battery went dead in less than two hours. My watch is basically unusable Apple needs a fix really quick!!

Get rid of MobyFace on your watch if you have it. That fixed it for me. I’d remove any other 3rd party apps for now too to be safe.
