Apple Watch 6 battery draining in Watch OS 7.6.2

I did not have any issues with battery in watch os 7.5, or 7.6, but since I went to 7.6.1, 50% of the life is gone. Meaning my battery used to last from 7am until 10pm, without doing a workout or streaming music. By 10pm it would be about 35%, now it goes from 100% to 50% in like 4 hours.

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

Update 6.2.1 Battery Draining Too Quickly… - 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.

Have this issue aswell on my 44mm applewatch 6 GPS , it worked great and never had any battery issues and was surprised how long the battery lasted even when doing daily phonecalls on it. Well after this update the battery is draining just by looking at it

, did the unpairing and reinstalling but so far it doesn't look like it's helping.


Very dissapointed in apple as per usual , worse and worse updates.

I'm facing the same issue. The 7.6.1 update has ruined my perfectly fine working watch in terms of battery drain. My watch used to last for 2 days on a single charge. Now, it doesn't even last for an entire day. I've tried all the possible options mentioned here but to no avail. Hopefully, Apple rectifies this issue!

I have the same issue, my series 4 would last all day, I would charge in the morning while I showered and it would last me through the day and the night (I use it to track my sleep). This morning it was at 80%, I went and swam laps, it died, and now it's charging REALLY slow and loses 1% of charge every ~5 min. I know it's not the newest model but still, the watch is only 2 years old. It also gets super hot while on the charger. HELP!

This is absolutely a problem with 7.6.1. My Apple Watch 4 has just gone from 100% to 9% in 6-7 hours, and I've done nothing but alternate between standing & sitting at my standing desk throughout my normal workday. I've noticed it being much worse since installing the update a few days ago but this renders the watch completely unusable - and there have been snafus like this on updates in the past.

I posted a few days ago that I was having this same battery drain issue after the last update. Like a few others posted after several days it is now using battery power the same as before the update without me having to do anything. Since I don’t remember what day I did the update so not sure if it took exactly 4 days to fix itself. Hopefully that happens for everyone else.

As much as I've enjoyed my watch (Series 4) in some ways... I've been incredibly disappointed in the bugginess of watchOS and related updates. Having to re-pair or completely wipe my watch every couple releases is frankly unacceptable for an ~$800 piece of technology (stainless steel with AppleCare, in my case). Certainly can't say I'll be buying another.

I have the same issue it past several days and now it is improved a little in the beginning it drained from 100% to 0 in 5 hours!! And now it last 10h it is still low before that my watch last 24h it’s Apple Watch 5 lte version I did full restart without unpaired it and still nothing I will update if it will improve more then 10h

Same issue here. I mean, the battery life *already* needed improvement, but after 7.6.1 update it *really* seems to be draining. For instance: I wear my watch at night to track my sleep. Last night I charged it to full, and I only put it on when I was crawling into bed. When I woke this morning it was at 65%. I do not have cellular turned on, night settings are activated from 11p-7a, and there is no background app refresh. 45% overnight?! That’s just ridiculous. C’mon now, Apple.
