iOS 13.6 overheating and battery drain issues

Hi All, anyone experiencing severe battery drain even after 13.6.1, pls chk your phone for mother board issue. especially older devices and experiencing battery drain issues after 13.5.1,. until 13.5 totally no issues with my phone. my 6splus had severe battery drain issues. i took to service center and they suspect mother board issue causing battery drain. its very expensive to replace. almost same price as phone price. also i was offered to one to one exchange, i have to pay additional 400dollars to get the same model. $489.00 to replace mother board. i chose to take it to mobile shops to repair mother board. anyways my phone is not under warranty now. under my own risk. once i get back my phone, i have to see the performance.

I'm currently updating to 13.6.1 and I hope the overheating and drain (I've been expecting since 13.6) like as others doesn't continue. From what I read here, I almost think I should contact Apple Care. Has anyone done so and what do they recommend?

I usually charge my phone in the morning, so at the end of the day at night i am left with 29%, I switched off my Wifi and all things and get ready to sleep, after half an hour i see my battery it went from 29% to 24%, whats happening, i checked my battery stats and nothing is coming there, can you explain plz? I am on 13.6.1 by the way, Restored though itunes, turn all features off if you ask me?

The problem comes when that 5% is taken off (29% to 24%) without doing anything on standby and when both Wifi and Mobile data is switched off and then in the morning (Overnight) it takes more 5% which is to blame why is battery is taking a big hit?

Then what would you say about me, I have iphone SE which I bought around 10 days ago and trust me the battery life is horrible after IOS 13.6 update. When I bought the phone the phone was on IOS 13.5 and it seemed excellent but after updating to IOS 13.6 the battery life as well as heating issue arised which I never had on any of my previous iphones. After updating to IOS 13.6.1 the heating issue seems to be fixed and the battery life remained same. Yesterday my phone was at 85% when I slept with wifi and mobile data off and today morning it came down to 75%, WTF? If it happened on android I never would have told but on IOS with this world leading optimisation, It was not acceptable apple. And Mr. Apple Employee, rather explaining us About idle battery drain considering my phone is only 10 days old. Try fixing it in the next update. It seems that whatever the problem is, you will always deny that and make excuse of this and that..... Apple you should definitely fix this goddamn issues in next update.

I don't understand the Apple - if is that hard to make a ”nice and smooth iOS”

If iOS 14 doesn't make better battery life and no heating my iPhone 11 - bye bye Apple (after my iPhone 4, 5s, 6s, 8 and 11)

So what do you see the solution to this problem? They checked my phone at an authorized service center and said everything was ok with the battery. After all, I will not wait more than a month for a new IOS, which is not sure if it will solve the problem.

If Apple Support says there is nothing they can do for you, and if you are unwilling to wait for a fix, all you can do is purchase a different phone, whether that is a different iPhone or an Android.

That's not to belittle your issue, it's just the most pragmatic solution to the problem.

As other Apple users here, we have no idea of what issues are being worked on, or what may be fixed or changed in any upcoming iOS release.

I know this won’t help those who upgraded to 13.6, but for the last 2+ years I do not upgrade without doing significant research on bugs / performance degradations.

I begin with Forbes(.)com, as there is a columnist who has been pretty reliable. Recently I also began monitoring these postings.

Also Google “iOS 13.6 bugs”

Is it inconvenient (and unreasonable) to have to double check before upgrading?

Certainly.

Has it saved me from the issues people are reporting?

Definitely.

Ever since I updated my phone to 13.5.1, my iPhone 7 is overheating and its battery is draining immensely. The phone heats up to such a level that it is uncomfortable to use anymore.

Well I didn’t charge my iPhone 7 Plus which I bought almost 4 years ago properly and its battery health level is currently still at 87%.

What I find out is that both iOS 13.6 and iOS 13.6.1 bring deteriorated performance and unusual battery drain to my iPhone 11 Pro Max.

I have the iPhone 11 & after the update my battery life isn’t as good ... as well as my brothers brand new xr or xs has been very bad with battery & his phone actually completely crashed and hasn’t turned back on. It’s been days ..

Yes, there are proper and improper ways to charge a phone. iPhone’s Optimised Battery Charging option in Battery Health exists for that reason, but it only helps passively for overnight charging. Users can do that actively by avoiding battery level going too low and too high (>80%) for a long duration. That’s why iPhone’s Optimised Battery Charging will not charge your phone over 80% until the time you‘re going to start using your phone based on your habit which the phone has learned.

You may want to take it in and ask if that's normal. I'm at 96% after a year, so that seems a bit of a drop unless you watch lots of movies, play games, and thus recharge your battery a lot; normally we are to recharge when it gives notice (not before the low charge notice).

Thanks! I also check with MacRumors (though I admit that lately I've been updating without checking). I did it more for my MacBook Air (because it's older) and assumed less need for the newer devices. But it seems as if Apple is releasing updates with less testing (at least for their older devices and older is relative these days) then they did five or so years back.
