Apple Watch Battery Drain Issues after Update

Since updating to WatchOS 10.0.1, the watch battery charges only to 80% overnight and the battery drains more quickly than before the update. I also updated my iPhone 14 pro to iOS 17 around the same time. Would this impact the watch battery?

Here’s my situation today:

  • wake up at 6 am: watch is at 100%
  • get in car at 7:20 am: watch is at 91%
  • sit motionless for four hours
  • at 11:30, walk around for approximately two hours (no workout being tracked)
  • sit motionless for another two hours
  • by 3:30 pm, watch is at 56%, having only been looked at 6-7 times. There were no functions engaged, only one alert shown, no workouts tracked, and WiFi is turned off.
  • since I have to leave the office at 4 and drive for about 3 hours, I fully expect that by 7:30 pm tonight my watch will be dead, having not done anything at all today.


I have updated my phone OS also.


Before this update, my watch lasted until 12 am-1 am, which included a minimum 2 hours of workout tracking and many activations.


this is an utter joke. Nobody can use a watch that can’t last 10 hours even when it’s not tracking anything.

I’ve got the exact same issue and it doesn’t make me feel better seeing all these people impacted.


Is anyone from apple going to provide an answer for a solution through this forum?


I already tried all the tips about battery draining and even switched off background apps refresh, but the battery is draining excessively fast, about 5 hours, and before the update it was about 24 hours.

Update to 10.1 seems to have helped for me. Series 6 will now last for the day at least. Not sure if update solved all the problems as I stopped a number of apps and removed others so I'm not 100% sure it was the update that improved things. Odd, only affects some watches, but it is obviously a OS issue. Hopefully Apple will acknowledge and provide an update that will work for everyone!

Yes, we can easily surmise this is a software issue. What we don't know is which software at fault, or even more critically, why some watch owners are affected severely, some moderately, and others, not at all. The difference can't really be explained by how the watches are used. We have two in our household and both are used in essentially the same way. One is unaffected. The other drains far more quickly than before (but not as badly as some report here).


Personally, I suspect it's got something to do with wi-fi or Bluetooth, a theory that wouldn't be difficult to test. A person with severe battery drain could turn off wi-fi on their watch and keep their phone in pairing distance for a few hours and see what happens. Then try the same with Bluetooth.

Okay guys. I read through here and saw instructions to delete any third party face apps from your watch and phone. I had one “MobyFace”, that had Star Wars faces. My series 8 was using a charge in 4 hours from 32. It has just dropped only 2% in 1.5 hours so my bug seems to be fixed. I also went to a face that just has the time for now. That may be the reason mines okay or deleting the third party app may be the fixer. I’m about to use a face with all four corners having info and see how it drains. That will gives us the key. I’m happy now I have a good charge.

Had the exact same issue, Apple Watch 7. After 10.1 the battery was draining, in 5 minutes I’d lost 3% just a few hours down to 10%


I reset the watch, restored to a previous version of WatchOS and that sorted it! It’s since updated itself to 10.1 again and no issues


Last charge was to 94% and eight hours later and a workout it’s only down to 59%.

I’ve seen people posting about eliminating third party faces like MobyFace and Facer. I happen to have a year long subscription to Facer. Why should we have to compromise with Apple about how we use or customize our watches when I have had my series 7 and used both these third party apps for better than 2 years without incident? Apple made promises about the increased functionality in their new hardware and software releases but we have to compromise how we were choosing to use our devices because their garbage software updates no longer support it? I am the customer who trusted their propaganda! If they can’t give me the functionality they promised, they can kiss my *** if they think I’m going to bend over backwards to keep their inferior product. They owe me a quality product; I owe them nothing, certainly not extreme loyalty when they’ve broken faith with me!

Or maybe Apple sent the specs for the update to MobyFace and Facer and they haven’t written code to read over properly. That’s normally the problem. Developers don’t code correctly. They get the update way before it goes public. The developers code to Apple’s software, Apple doesn’t code to their app. That’s like buying an aftermarket camshaft for a Chevy engine and getting mad at Chevy it they made the shaft or lobes wrong. Anyways, I need my watch to be functional more than I need a third party face. That’s just me though.
