WatchOS 10.1 battery drain issue

My Series 8 watch upgrade to WatchOS 10.1 this morning and now my watch battery drains in 2 hours or so. What is the fix for this?

If the battery drains too fast after an update, see all the replies to:

WatchOS 7.5 battery drain - Apple Community

FWIW, in some cases, unpairing the watch, completely erasing it, then pairing and restoring the backup will resolve the battery draining issue after an update. (Simply unpairing and pairing again may not work.)

Also, some people have found that simply waiting a few days after an update resolves the battery draining problem.

My wife's less-than-month-old series 9 heated up when charging, didn't charge, and the battery dropped rapidly. Took it into the store... sent it in to Apple... was shipped back today. They said they couldn't replicate the issue (Apple Genius couldn't get the diagnostic system to work on her watch) and sent it back. Let's hope it's not broken worse or back to BB it goes for a swap.

I have same issue. I mean not exactly the same. I restored yesterday my iPhone 15 pro because I tried to achieve better battery results. After paring my watch (set as new) battery was draining way too fast. Unparing didn't help. Hard reset? Nothing. Moreover I have a problem with Infograph face. in the middle I have a today's date. Above should be visible my next event or "no more event" or something like that. It worked before restoring. Now I doesn't. iOS 17 and new watchOS 10 are so buggy.

P.S. It is not only about this Moby app because I've never heard of it and still have a problem.

Watch OS 10.1 has so many bugs.

I have to reset my watch at least three times a week now because it does random weird stuff or forgets to display stuff. Notifications freeze up my watch or you click on the notifications and it does nothing, not to mention drains my battery. Fitness tracker shows multiple different readings and sometimes different to what’s on the phone. It is really cooked at the moment. Do they not test anything anymore ?

Sometimes my calls don’t come through on my Apple Watch even though my phone is connected and I have cellular on my watch. listening to music with headphones & it will just randomly switch to the Phone and start playing the music through the phone or start playing completely different playlist from the phone…. The list goes on.


This is really put me off owning an Apple Watch. used to love it now it’s just extremely frustrating.

Someone told me that 3 party apps have restricted background activity. But he mentioned about "side effect". He can't tell anything more because he is saying about theory. Anyway I think that 3 party apps can trigger something like location etc and even If you uninstall them this process is still running and drains your battery. So yes maybe it is apple fault but for customer it doesn't matter. Draining is draining. Check MacRumors forum

I have tried low power mode to jump at the end of the day, but it’s still draining battery. Nothing changes. I have tried to remove all third parties apps. I have tried to unpair. A brand new series 9! This is the first time I experience something like this. My sister has now my “old” series 8 and it is PERFECT. Battery life is 100% and duration is about 30/34 hours! Unbelievable
