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.

Updated to 10.1 and saw battery drain immediately. I had a full charge last night and by time I got up, my watch was dead and turned off. I did a factory reset and turned off background app refresh. Battery is coming back a little bit - it's been charging for over one hour and it's only at 40% full. My battery was fine on 10 but the update really messed it up.

I wasn't having any issues after updating to watchOS 10.0 (or any of the sub-updates) outside of the weather complication glitch, but just updated yesterday to watchOS10.1 on both my Apple Watch Ultra and my wife's Series 8. We couldn't get past the 80% charge (even after turning off Optimized Battery Health in order to charge it to full last night), so when we went to sleep last night they were both at 80%. My Ultra drained to 5% in 7 hours (I would've lost maybe 5-10% over that time period in the past) and my wife's Series 8 lost all its battery and went into Power Reserve. Not only that, but I seem to have lost the ability to fast charge my Ultra (tried two different chargers).


Called Apple Support this morning - I was a bit concerned when the person I spoke with asked whether the watchOS10.1 was a beta version as they hadn't released 10.1 yet (I've never run a beta version of any of the OS on any of our devices before). She ran a diagnostic, and everything was fine (not surprised). Her solutions were either to go to an Apple Store (which seemed like it wouldn't make sense, since to me this seems like a software issue so what is an individual at the store going to be able to do), or she would issue a ticket to some internal site, and if that gets enough 'hits' or 'votes' then it will be a priority for the engineers to work on that issue in an upcoming update. I'm assuming they will be receiving plenty of calls with a battery issue that essentially makes the watch obsolete, but I'll encourage others to contact Apple Support if they're having similar issues to make sure it's on their radar. Be prepared to not get a solution, but hopefully with enough calls, the problem will get solved.


I will say I've been disappointed with the recent OS rollouts (I'm a huge Apple Fan - have all the devices), but iOS17 gave us issues with morning alarms, I saw a complication glitch with weather in watchOS 10, and this issue is huge. From here on out, I'll be thinking twice about running an update immediately (fool me once...).

Ok so after a trip to the Apple Store yesterday, here’s what I’ve done this morning at 6:30 with my watch at 100% and is now at 97% 4.5 hours later. Reset the watch and setup as new. Keep in mind I’m on 17.1 beta on my phone and 10.1 (no beta) on the watch. I turned off the noise app and went into Cellular to turn off cellular data for most apps that I don’t use with my watch. Any apps that I don’t have to have I’ve uninstalled from the watch. They also told me yesterday that my watch face was also pulling the most battery because it had been pulling data constantly to keep the watch face updated. Hope this helps.

I got to work this am to a dead series 8 watch. It had a full charge 9 hours earlier. Six hour later I have charged it twice to 75% and it has gone below 5%…..

turn off twice and rebooted it. Actually had to do that after the update last night. It was not charging. Shut it down totally. Put it back on the charger. Got a full charge and it was dead 9 hours later.

I made an apple yesterday at the Apple Store, they ran some test on my Ultra battery. It passed, no issues.

It is giving me a message under battery that says it stopped charging at 81% due to temperature issues. I am using apple charger and cord.


The recommendation from the store was to call Apple tell them it is a temperature issue and that it is creating battery problems. I am doing the express repair since I have AppleCare and they will send me a replacement first and I will return mine. Then wait for them out come if what’s going on with the battery

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....
