Apple Watch battery draining fast

I did the erase and unpair option (keep the cellular plan) and then set it up as a new watch. It has been a few days and so far so good. Yesterday I started with 100% at 6:30 AM and 19 hours later I was at 34%

100% 6:31 AM

84% 11:11 AM (started to worry)

63% 5:30 PM (started looking better)

47% 8:11 PM

34% 12:56 AM (next day)

I was not doing much (e.g. basic apps like timer and various notifications.) but before erasing unpairing and setting up as a "new" watch I could not get through the afternoon.

I will be using a golf GPS app in the next few days. We'll see how that goes.

The watch. I did the erase and unpair option (keep the cellular plan) and then set it up as a new watch. I also shut the phone down completely and restarted it before I repaired the watch. It has been a few days and so far so good.

I'm running into the version of this where I'm having draining after doing a software update on both my watch and phone. On one of the threads around this issue, I saw somebody who reported fixing it by plugging the phone into your computer, and looking at the phone in Finder (or I guess iTunes on Windows, maybe?). And it'll show that it's running the latest version but there's an update anyways; if you click on that button, it'll do an update on your phone. And that mystery update doesn't change the iOS version number but I think it must contain some change related to this issue anyways, because it's been a week or so since I did this and my watch has been fine ever since. And yes, I am saying to do an OS update on your phone to fix draining on your watch.

Also, FWIW, for a short term workaround before I did the above fix, I found that if I rebooted both my watch and phone, then it solved the draining issue for a little idea. (Maybe half a day, maybe a day and a half.) Just rebooting my watch didn't work, it required rebooting both. So that's consistent with the idea that the problem is on interactions between the phone and the watch, not purely a watch problem.

I’m having the same problem with my S7 (12 months only and 90% battery health). Started right around when I updated OS to 10.4. Apple support insists it’s a “usage” problem despite no notable changes to my usage. Used to get ~30 hours, now maybe 12. Unless fully charged before bed it dies overnight. So much for a sleep tracker…

*** I had this exact problem and this is THE FIX THAT WORKED FOR ME:

1) I unpaired my watch (this makes a backup and then erases the watch)

2) Re-started my iPhone

3) Re-paired my watch (this restores it from the backup)

4) Turned off Automatic App Install in the Watch App (under 'General')

I don't know if this last step was necessary, but I was having constant trouble and now I have none - and the fix is lasting, not one bit of trouble since.

This happened to me a couple months ago too. It was after an update. I reset my watch to factory and that seemed to fix it. Now today, I’m traveling and it’s just a little after 2pm and I got an alert that it’s at 10%! I had to put it in low power mode. Great. I think there was an update about a week ago. I agree that customers shouldn’t have to troubleshoot and be expected to reset their device after every update. It’s ridiculous!

I took a chance and installed the last update. I mean, what could it hurt, it was basically unusable or reliable after the April update. So far, it’s behaving, and I’ve not had a drained battery since. (Crossing fingers).

I wrote a week ago that I had the same problem. I turned my iWatch OFF, waited 30 seconds and turned it back on, charged it and I haven't had a problem since. A friend of mine said she was having the same problem. I told her to turn it off and back on, recharged. She texted me that it's working now. Sounds simple but it seems to work. Good luck.

New batteries require several (3 to 6) charging cycles to reach peak performance. Brand new Watches have a lot of background processes going on, especially at night. Night is a normal downtime, so the CPU working on other tasks usually isn’t noticed or the hit to performance.

It's erase your Apple Watch. But the option that leaves it paired with your iPhone and retains the cellular plan if you have one (second option in this link). Unpair and erase Apple Watch – Apple Support (UK)

Same here! BS 🍏! “It Just Works” for a very short amount of time.

Fix this already, please.

Apple does not read this user-to-user technical support forum for feedback.

But you can send Apple feedback via:

Feedback - Watch - Apple

It will take 24-48 hours for the new operating system to finish it house keeping, as well as resync things it wants from the iPhone.

Power cycle the Apple Watch and your iPhone (at least once, but maybe once or twice a day until the Apple Watch battery consumption returns to normal.

How To Fix WatchOS 10.3 Battery Drain Issue on Apple Watch

For some steps that are not in the MacObserver article.

iPhone -> “Watch” app -> General -> Reset -> Reset Sync Data

Again it may take a day or two for the rsync’ing of data to settle down.

As a point of reference, my Apple Watch Series 4 with 90% battery health maximum capacity, was back to normal after 24 hours (watchOS 10.5). I did 1 mid-day recharge, and I power cycled my Apple Watch and iPhone twice.

Woke up this morning and the 10.4 update finally updated while I was sleeping. So now I’ll see if it actually solved the battery drain issue.

Mine start to drain from 100% to 0% in 4hrs start from 11April 11pm(GMT+8), same repeat next day. So frustrating

Also having the same issue with battery drain with the whole family’s watches since 3 days ago.

Thanks Amanda - This seemed to be the only thing that fixed the drain. It took a while for that progress bar to start creeping along, then all good after the 10.4 update.
