Apple Watch battery draining fast

I did this, with the added step of disabling automatic app installs and it appears to have fixed the problem.

thanks again

My series 9 watch was charged to 100% at midnight, by 6am it woke me up alerting me it was at 10%. Back to 100% by 9:30am. Once again at 2:30pm I’m back to 10%.

I do see a pending update for watchOS 10.4 that I will try to install when I get home and hope it fixes it

I have the 10.4 update and it’s not helping at all. My battery drains so fast. It was at 90% and I checked one message and then it was at 88%. I’ll try to unpair and repair since that seems to help others. But I can’t not delete the update. It’s not showing up.

Same exact thing happened to me starting April 11th. Same watch with the same settings but if I look at the battery app you can see the steep downward line showing the draining at a very fast rate. I even went to the Apple Store and they did some diagnostics and said there was nothing wrong with the battery itself. She suggested turning off background app refresh and turning the watch off and back on. I had already done the latter, and (reluctantly) did the former (i.e., turned off background app refresh) since I had never had a battery problem even with background app refresh turned on. Anyway, none of this has helped.

I should mention that the battery drain started happening before the most recent Watch OS update. I've since installed the new update and it has not changed anything for the better (although it is not necessarily any worse).

Anyone know of the reason for the problem and the fix?

I just got done reaming out Apple support representative in the end. They admitted that they’ve acknowledged that this is a problem with the update and they’re working on it so the person you talk to who ponded off on being our fault is wrong and should have never done that, but they are working on it.

I think there is a clue there. This was the same case with my Apple Watch Series 9 in my wife’s Apple Watch Series 3. My Settings had automatic software updates and Hertz did not and she has not had this problem at all. This is one more reason why I think the battery draining problem has to do with the automatic software updates and any files that downloads onto your devices.

Most things came back over from the apps they were associated with on the iPhone. I had to redo the watch faces. Not sure about health data but I don't really use that.

You could try restoring from a backup. Some have reported this works. I just wanted a clean slate.

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!

My Apple Watch SE unexpectedly starting manifesting the same symptoms. Battery health 91%. I removed some functions and then erased my watch and set it up as new. No change and still only operates for 5 hours. There doesn’t appear to be an Apple fix for this.

Sorry that is not quite right. Mine has been “stabilising” for a week after it unexpectedly started to malfunction. After waiting for three days to correct itself, I undertook a factory reset. As I was away on holiday I didn’t try anything else but simply recharged it as the battery power diminished.

I have just returned from holiday and after a further factory reset, unpairing the watch and even removing the app, I have left it for a further two and a half day days, after the initial 5 day “stabilisation” and it is worse. It is undoubtably a problem as Apple have asked me to return my out of guarantee Watch for a replacement.

So glad I wasn't the only one with this issue. Currently in the process of unpairing and updating per Apple Support. Fingers crossed this works.

After finally the update process, finally downloading I can report my watch has gone back to normal batt drain rate! Have lost like 1% in last hour!!!

Finally applied the update overnight, and watch is back to normal battery usage!

I unpaired and repaired with the new update, but if this doesn't fix it I will be doing the same. thanks.

Since doing the erase option but keeping the watch paired to the iPhone I can confirm that it does seem to have fixed the issue. Battery use is back to normal.
