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.

Why still staying with Apple when their updates break the watch and the support and the company does not really care about it.

(I heard or read nothing about an official communication on this topic from apple - and this issue exists since watchOS 10.0.1)


I switched to Garmin and everything works fine for me: my data is now in Garmin Connect instead of Apple Health - just another app for me. I could continue my journey on being reminded to do sport, measuring my sport activities and losing weight.

My broken Apple Watch is now waiting, until this issue is fixed and will then be used by my wife or son (Here's another hurdle built in by Apple: You cannot connect an Apple Watch S4 with watchOS 10.0.1 to an Apple iPhone 6, because the iPhone would not get an iOS 17 update ... customer and environment unfriendly !!!)


It's time for a change.

My series 9 watch only charged to 78% because of temperature issues. I went to bed at 9:30, and took it off the charger without a full charge. I received a low battery message that it was at 5% over an hour ago, and I just woke up at 3:45 AM. I haven’t even made a full leasing payment to my cell provider for this yet. But I’m done. I am not committing myself to stand by this product anymore. Once my cell phone is paid off, I’m cutting ties to Apple all together. This is terrible. Yeah, I’m done.

I seemed to have resolved it .

Here is what I did

Got enough charge in teh watch to last about 15 minutes

unpaired the watch and it reset

re-paired the watch , restored from my last backup.

removed all the watch face aps , clockology , etc....

put watch into power save mode.

Put it on the charge cradle for the night .

Woke up this morning to a 100% charged watch .

So far this morning it has used 1% , which is what I normally expect .


Hope this helps ........

ios10.1 Watch update - My watch used to charge in 30mins, now after 3hrs is only 50%. The full charge only lasted 4hours before low battery warning has come up. Previously would last 2-3 days.

iOS 17.1 iPhone update - same as the watch. Battery is draining quickly. Have had to recharge is three times during the day when I would never have to charge it during the day - only used to charge it at night.

I don’t think that sending a watch back or buying another watch is the answer unless there is damage caused by overheating or something. It seems that the problem isn’t the hardware—the watch—it’s the latest software update(s). If you get a different watch, and it has the same faulty OS on it, it’s just going to have the same issue(s).


It’s unconscionable that Apple is pretending that there is no problem with the OS.

The strangest part of this problem is, it doesn't seem to affect everyone, isn't specific to an Apple Watch model, and for those who have it, the increased battery drain varies hugely in severity. Also, the solutions that seem to help some owners don't do a thing for others. Not surprising Apple is having a hard time figuring out what's going on, especially if their diagnostics are showing nothing wrong when so clearly something is very wrong.

Oct 27, 2023 9:57 AM in response to Mitch Stone

Pardon me for being a skeptic, but I'm not convinced that Apple's diagnostics are showing nothing wrong. Too many users are having the same problem for Apple to be seeing absolutely no issues in their diagnostics. It's just easier for them to deny it, perhaps while they try to figure out what's going on. After they know how to fix it maybe they will admit that there was an issue.


And the reason that the problem is not specific to a particular Apple watch model is that the issue is a software issue, not a hardware (watch) issue. This is clear given that before the "upgrade" to 10.0.1 no one encountered the issue. The variation in the severity of the battery drain can be explained by what apps people are running on their watches, how much they use their watches, whether they've got apps running in the background or only when in use, and things like that.


I can't explain why some people see improvement when they try suggested fixes; this could be related to the variables that I just described. They seem to be temporary improvements, and not permanent fixes.


Don't buy a new or refurbished watch. You'll just have a different watch with the same OS if they're shipping watches with the current OS, and you'll have the same issue because it's not the hardware, it's the OS. Unless, of course, you get a watch with a version of the OS prior to 10.0.1, and then ensure that you do not have it set to do automatic OS updates!


The bottom line is that there is a problem with the software, and Apple undoubtedly knows about it, and they are responsible for fixing it. But will they, and how soon?

Series 8, less than a year old. Ever since 10.1 beta, I’ve gone from 34 hours a charge to 4 hours. I’ve cleared and reset the iPhone 13pro, watch8 and still having same battery issues. I can’t wear my $400 watch a whole day working now. I have to charge it at lunch. This is some third world company failure. I have on me and in my home with MacBooks, HomePods, iPads, watches and phones over $3K worth of great hardware. Stop rushing this ****** software out and be as dedicated to me as I am to you Apple. We need a fix yesterday!

I saw on the internet that the .1 for Mac is bad too. I am holding off in updating my iPhone and my MacBook.


I followed the advice of a person on this chat and unpaired, restored from last and took of a watch screen software. Then I put it on lower power mode. It is not great but is better. I hope it helps!


Thank you for the heads up on 17.1!
