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.

Just an update on this post. I found a solution that worked for me. It probably won’t be a solution for others as this seems to be a bit if a mystery on why this happened. 

The short story: I deleted all those third party watch face apps. That fixed it. 

The longer version: First thing I did after having the watch off all night was reset it as new. Took awhile because the battery drained really fast while it was  repairing. Had to wait for it charge back up so it could finish. Honestly, it was a waste of time. The watch wouldn’t even charge. Stayed at between 15 and 17 percent. 


In one of these threads here someone mentioned removing the watch face apps ( it was either Facer or Moby Face) so on my iPhone I deleted all of them (I had four) and waited. My watch was at 100% within a half hour. And it was cool to the touch. Not hot. It is now about 7 1/2 hours later and I’m down to 74%. Which is normal. I expect it to be better tomorrow because I won’t be fiddling with it as much. This also solved another problem (which I posted in another thread) The iPhone Watch App was misbehaving. All changes made to any of the faces, added faces or deleted faces wouldn’t sync over. I couldn’t even change faces from the app. This fixed that too. 

Not sure why these app made this mess. Bad code. Not updated for watchOS 10. Who knows. But if you have these apps try deleting them. 


edit: Seems to be what others are saying. Delete those apps. That should do it. But like I said. Might not work for everyone.

You are not alone. I am seeing tens of thousands of users (including myself) reporting battery stability issues on various Apple watches after updating to Watch OS 10.1. There is clearly some sort of bug or complication within the new update that excessively drains the battery.


Some common recommendations I’ve noticed are to uninstall all third-party (non-Apple) apps from your watch, and to charge on Low Power Mode. These recommendations clearly hinder the convenience and efficiency of owning an Apple Watch, but it will at least prevent potential damage to the battery’s overall health.


This is absolutely insane. This update has been available for some days now and Apple has yet to release formal communication that apologizes for, or even acknowledges the battery problems with 10.1.

i have an ultra 1 and it was dying within a couple hours after the 10.1 update and wasn’t charging past 70%. I turned off optimized charge limit and deleted moby fox and so far it’s back to normal. There will hopefully be a patch update on the next firmware update to fix this but this seems to be the work around for the time being. I will fully charge tonight and test on full battery tomorrow.

This was the case for me. Erasing all the content, hard resetting or shutting off the watch didn’t fix the battery drain but once I offloaded every non-essential app, my Series 8 started functioning normally. I really wish I had done this first; setting up the watch from scratch several times was a real pain and I still have to recreate all my watch faces.

I’ve never dealt with a problem with this from my series 7 right before receiving my series 9. The best thing I’ve found to do on another thread is to delete the MobyFace app if you have it installed. After doing this my watch stayed on 27% and now it’s on the Belkin charger I have. If you like the app you can keep it on your phone and receive the photos for your faces that way especially if you purchased bands from them (South Park,Rick and Morty)

My Series 6 went from lasting all day, to losing 1% per minute when undocked (this is how it felt, I didn't actually time it). It also wouldn't charge when docked, stuck at whatever percent it was at. If I undocked it and it lost a percent, and I docked it again, it would get stuck there. Doing a force restart allowed it to charge again to 100%. However, it was still losing 1% per minute when undocked.


I tried force restart (holding both buttons). Didn't work.


I deleted Moby Face from both watch and phone, then tried force restart again. Didn't work.


I also force restarted my phone. Didn't work.


I erased all content and settings from the apple watch, re-paired to phone, and restored from backup. Didn't work.


I gave up for 2 days and just left it charging the whole time, with it was stuck at 100% the whole time.

Today, I looked at it, and thought, let me force restart it again. Now, it appears to be working. It's been 1 hour and has lost 2% so far, which is normal for it (It's a series 6 at 83% health).


I have no idea what in this chain of things I did fixed it, or if it will stay fixed. It's only been an hour and I'm writing this post.


Based on what someone else said, they also had to erase and pair the watch, and then force restart it after to get it working again.


I didn't delete any other 3rd party apps, and I don't know if Moby Face was the actual culprit since deleting it didn't seem to do anything. But so many people are complaining about it, maybe it somehow weirdly played a part.


I would suggest trying the following based on no scientific reasoning:


  1. Delete the Moby Face App from both the watch and phone.
  2. Erase All Content and Settings form the Watch's reset menu.
  3. Pair to iPhone again and restore from backup.
  4. Force Restart the Apple Watch after it's done being set up.


Hope this helps. Sorry if it doesn't. Everyone seems to have such different solutions, making this issue difficult to troubleshoot.

Same issues for me after installing 10.1. Apple ran diagnostics on my Apple Series 6 - and found nothing wrong. They then sent me to the Apple Store to do more troubleshooting - the Apple Genius did a clean Factory Install which seemed to help - and (what I thought) fixed the issue. Then I got home an hour later and it the watch was dead. Others in this thread have reported that removing the Moby Face app solved the issue - there could be other 3rd party apps that have yet to be updated causing this too. I've now uninstalled a couple things (including the Moby Face app). Here's hoping, fingers crossed.

Just to update you all. This may be relevant to some but those with MobyFace app on their watch remove it from the watch turn off and on and this should fix it. It’s done it for us. Those who don’t have it. Maybe look at apps that have and haven’t received an update recently and delete those that haven’t and hopefully that will work. Hope this works for you all but like I said MobyFace is our culprit and may be yours

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.
