Apple Vision Pro is now available in the U.S.

Apple Watch battery drains super fast after 10.1 update.

Series 7 Apple Watch. After 10.1 update my battery only lasts a few hours. I can literally watch the percentage go down. Rebooted the watch. Shut off background app refresh after advised by a friend. Still drains ridiculously fast. It’s essentially useless now. I’m out of ideas. Anyone else have this problem? This is crazy.

My watch used to last two days, even with me running an hour a day. I no longer run and now it drains faster. I have to put it on the charger overnight and again mid-day. Normally, it takes about an hour to charge. But there are days that it takes up to five hours to hit 100%. I haven’t added anything or changed any settings since I got it almost two years ago.

Thanks. I have removed all third party apps and battery still drains too fast. The only way I can get 8 to 10 hours between charges is by deploying draconian measures, which I have posted elsewhere. I have even found problems with Apple apps not working correctly, such as Apple's heart rate monitor app, Apple Workout app, and Fitness+ integration.

Yeah, people keep saying to delete the MobyFace app. So I unpaired and repaired my watch. When it was loading apps, I selected to not install MobyFace but IT DID IT ANYWAYS! When I select it to not show it on my watch, the green slider is greyed out and I can’t swipe it in list mode and there’s no x when I get it to jiggle. WHAT THE HECK!!!!

Thanks for the tip. I removed my Moby Face app yesterday. I then turn my watch off for 15 seconds and then put it back on. It is no longer getting overheated while charging and is holding a charge now. I ended up deleting a few other 3rd party apps that I realized I had but don’t use my watch for so it was just wasting storage. My watch 100% at 1:53pm yesterday and was 66% when I went to bed around 10:30pm. So he definitely is better. Again thanks for the tip.

I see that people are saying to delete 3rd party apps to make it work. That doesn’t seem like a good fix. We should be able to use that apps we want. Hopefully 10.2 will come out and fix the problem soon.

A number of people have discovered that a particular 3rd party app is the source of their problem. Removing it seems to solve it. That doesn't mean that they can't use any 3rd party apps, just not that one until it gets updated. So, even if you don't have MobyFace installed, it's worth removing all of the third-party apps and seeing if your battery life goes back to normal. If it doesn't, start adding the third-party apps back a couple at a time. If the battery life suddenly goes haywire again, you'll know it was one of the most recently added apps and you can remove only those.


Other people report that they don't have third-party apps and are still having issues. That highlights something important: the same symptoms don't always have the same cause.

I called Apple. They ran diagnostics. Told me to take it in for service. I get there and was told they cannot service the watch due to the battery health being above 80%, unless I want to pay $70-350. The tech was baffled. He went to the back and was gone a long time. He talked to other techs and they said there was a LOT of chatter online about the last update and the Moby Face app killing the watch. He sent me home with a dead watch and told me to call corporate and complain. The real nugget was when he said Moby Face as I use their watch faces sometimes. Sure enough removing that app from my watch fixed the battery issue! Seems Apple is trying to avoid people sending their watches in for service when it’s actually software… which makes sense.

Like many others I took MobyFace off my phone and now my watch holds charge and performs normally, with all the other 3rd party apps I was using installed. MobyFox has admitted they know their app doesn't work right with 10.1 (they aren't the only one as there are some others, but theirs seems to be affecting a lot of folks in this discussion) and are working with Apple to figure it out. Hopefully when they get it fixed and I reinstall the app, I won't have to reload all the watch faces again since I have several watch bands.

yeah, Apple tech support seems woefully unaware of this. The Genius Bar was like 'well, turn off background refresh and you uninstalled all the 3rd party apps, so, that's all we got'. This discussion was far more useful and you would think as long as it is, their Geniuses would be briefed on it. Sadly MobyFace does not actually install a version of the app on the phone and instead communicates through the Watch app and was clearly doing something to seriously ping the watch constantly, though I was not seeing battery drain on my phone.

I got an Apple Watch series 9 in September 2023. I use it mostly for fitness and to better my health. I updated my watch to 10.1 and it went from 100% battery to 35% in two hours. So I called Apple support and they did some diagnostics and had me recharge my watch on low power mode and then wait to see if the battery issue happens again. It did of course, so I called again and they had me unpair my watch from my phone and then re-pair my watch to my phone as a new watch for 24hrs and see if the battery drains again. It did happen again, my watch battery went from 80% to 10% in one hour. It also couldn’t fully charge because the watch was getting too hot. So, I took my watch into an Apple Store to have it sent out and fixed. I got it back in a week and nothing had been fixed, the battery was still draining within a few hours. So, I looked on these discussion threads and found that some people had taken off all the 3rd party apps and that seemed to fix the issue. So, I did that and it worked! My watch charged to 100% and the battery didn’t drain at all.

The MobyFace app was updated today to version 2.9.5. If you have automatic updates enabled it probably downloaded it in the background.


Apple is aware of the issue and a fix will be available in the next iOS update.


The best we can do is work together as a community and give possible solutions to fix this problem until an iOS update is released.
