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

Battery Drain since watchos 7.4 - Apple Community

WatchOS 7.5 battery drain - 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.

My Apple Watch series 3 battery has been draining. It will be 100% and in about 4- 4 1/2 hours it will go down rapidly to 33% and then 10%. I have had this issues for months now. I’ve taken in to Apple, Best Buy and did all the troubleshooting as they advised( unpairing, factory reset, you name it) and still the same issue. I’ve had this watch for only over a year and use it just to read text messages from my children and nothing crazy on the watch.

i don’t understand with all the updates, it seems nothing is being done to fix it. I am sure I’m not the only one with this issue.

i want to add they also did a diagnostic on my battery and life span was 100%. Please Apple the products you sell to us consumers aren’t cheap, can you all please look into this and make us Apple supporters happy for once.

I’m going to test this “update” out and see what it does. I wondering if it will do something to my cellular series 3 watch as that one worked just fine and didn’t experience this battery drain but the non cellular one was the one that was getting killed in battery life and I basically went on both watches and turned on and off the same features just to see if that would make things better and again the LTE watch worked fine while the GPS only watch battery was draining like crazy.

Sorry but for my watch the update of 7.6.2 did not fix the issue, now I updated the watch twoday ago with also an initializing of it, but the problem of the excessive draining battery remain the same. Yesterday I had a chat with the support of apple (with the app support) they checked my watch via remote and they told me that the battery is ok and it did not have also problem related to the software. The support gave me an appointment for today at the apple store near my house to verify the watch, sincerely I hope that it will be replaced under warranty for unknown problem of excessive battery drain.......

I have AW 4-44mm only gps with iphone XS max


P.S.: In the past I tried to: erase the watch many times, pair/unpair the watch, formatting also iphone.... nothing help!!!

Yeah, this update has not resolved the battery drain issue on my Watch Series 4. Not sure whether Apple is paying attention, but you just lost an Apple Watch customer. If you'd fixed this issue (which has been WELL publicized and reported) in this update I'd probably have ended up buying one of the upcoming generation, but I'm sick and tired of having paid $800 for a beta program - and I'm not only referring to this particular battery drain issue. It's simply inexcusable. In all seriousness: anyone have a good recommendation for an alternative smart watch? Or perhaps the Oura Ring?

I agree all Apple products are expensive and I told myself too I am not going to get a new watch. I’ve got the series 3 and alittle over a year and really got it for when I’m at work and can’t be on my phone.

I am very Frustrated that Apple is aware a lot of their consumers that own the watch has had issues with the battery and still can’t fix it.

The battery would last a alittle over a day into two days without me charging it and now just plain horrible I’ll be lucky if I get a good 5 hour battery life.

And my device is the IPhone 11 Pro Max so no other issues except this darn BATTERY!!!!


APPLE PLS FIX THE BATTERY DRAINING ISSUE FOR US ASAP!

Sep 16, 2021 7:16 AM in response to bm3088

I hate to pile on but yeah, ever since updating my Series 6 to 7.6.2, my battery goes from 100% to 10% in just under 10 hours. I've changed NOTHING with regards to how I use the watch and I've not added/deleted any apps.


I charged my watch overnight, put it on at 6:30 am this morning and now at 9:15 am, it's down to 78%. It's these kinds of issues that make me hesitant to update the OS on any device - regardless if it's a security update or not.

After the software update( most recent), I have unpaired my watch and also powered it off and back on… Unfortunately, same issue my battery is still draining real fast. Within two hours, I removed it from the charger to step out the house and came back home within that time period and found the battery percentage was down to 66%. This is so disappointing that after all Apple does nothing to fix these issues. I continue to hope they will attempt to correct this issue and make us Apple users happy. I hold firm on my decision to not replace my watch for a new one because I’ve had my series 3 for over a year and still in excellent condition.


Sep 21, 2021 12:52 PM in response to SassyKae

The issue started with watchOS 7.5 and they never fixed it as they did with watchOS 7.4 if I’m not wrong. Not sure about the version but it definitely happened before, and fixed with an update. I’m sorry you are spending 95 $ for nothing. People even got their watches replaced by new ones under warranty, just to have the same problem

Sep 21, 2021 1:08 PM in response to SassyKae

Well I took my watch to the Apple Store and the tech wrote up the order as a free battery replacement. I got an email saying that there wasn’t anything they could do as the Diagnostics scan showed the battery at 100% healthy life. So they sent it back and said oh well. Me and a tech on the phone got into it as he basically didn’t believe my claims.

Sep 21, 2021 1:13 PM in response to SassyKae

I was advised I could get the battery replaced regardless if my battery life span was at 100%( battery is in good standing) and pay the fee but it won’t guarantee that it would fix the issue of the battery draining. This was told to me at the Apple store when went in for an appointment with the genius and also took it to the Geek Squad at Best Buy for a second opinion.

please do let us know how that turned out, Good luck!
