iOS 13.6 overheating and battery drain issues

Same problem here with 7plus. Unusually hot on charging and fast drainage even if phone is not in use. Thought initially that it may be due to the polythene that I used to cover the phone while in hospital. Turning off and back on multiple times didn't help. I'm not confident with resetting, since never done before.

Also when I’m charging my iPhone 11 Pro Max with the cable provided together in the box it may freeze or becomes hella laggy sometimes. This is hella weird and am wondering what’s going on with Apple’s developers these years... every single update seems to be glitchy and problematic.

Just updated to 13.6.1. Now it’s even worse if you can believe it. The battery drain is outrageous. Really pointless in even having a better anymore since it always needs to be plugged in.

just lost 10% in the last two minutes.

thanks apple.

Probably they ain’t gonn fix it till iOS 14 comes and that’s their tactics maybe cause all the last versions of every iOS contains weird bugs that they won’t fix. There’s very unlucky of you to experience that tho cause that’s a 2020 phone. Luckily mine has a large battery so I still only have to charge once a day even with this issue. But it’s a lil frustrating cause the photo app and the keyboard for my another language both have bugs after the iOS 13.5.1 update and they ain’t fixed till now... smh

So to clarify, 13.6.1 improved the overheating but did not improve battery usage,

My recommendation still stands. Rebuild your portfolio. If apps and cloud traffic use too much battery in iOS13 they probably will do in iOS14 or 15 too.

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?

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.

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.

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.

Well I did charge it to 96% most of the time (but I did charge my old iPhone 7 Plus to 100% every day for 3 years). I mostly use the device to send iMessages, surf Facebook, insta and Snapchat. I dun really use my phone that frequently.

I tried this for my other devices many times during years. My current iPhone 11 Pro Max stores 26,573 photos and 781 videos and I reckon this is the reason why my built-in photo app is always crashing. I back up my iPhone with iCloud backup cause the one on MacBook is extremely annoying and time consuming. I will take my iPhone to Genius Bar for a battery replacement before the warranty expires so I ain’t gonna do it for now. But do thanks peter_watt for the useful suggestion and resources:)

If you did import them to Mac Photos then sync them back they would take up half the space. Just sayin.

If you use "icloud photos" remember that is not a backup; it is a sharing mechanism . If the phone packs up they may well disappear. Ensure you are using icloud backup or Mac backup as well as icloud photos. Another reason I import then sync
