iOS 13.6 overheating and battery drain issues

This started out as a promising Q&A on the battery drain issues with 13.6, but the conversion took a turn and the issue was never addressed.

I downloaded 13.6 Thursday and since then my phone runs hot and my battery life is terrible. Anyone else having issues?

@cid176, dont worry bro.. there are other users having same issue, including me. my 6splus is warm while charging and during use. my OST is only 1hr20mins. not much background activity after updating to 13.6. seems no fix for the battery drain issue..already tried clean install, and other steps to troubleshoot.my battery health dropped from 100% to 97% after updating to 13.5.1.. apple support says my phone is working fine.

I've restarted my iPhone SE running iOS 13.6 twice too and it has not resolved the issue. I have had a massive drop-off in battery performance over the last two weeks or so. I've also done many other basic housekeeping tasks like closing apps and some location services to try to save battery. My battery health is 90% so that doesn't seem to be the problem. I'm hoping the next operating system release fixes this issue and quickly!

I've turned the phone off and on several times, and even reset the phone and restored it from backups twice.

Same problem with my iPhone SE2. My battery health was 100%, after upgrading to 13.6, the first day, the battery health became 99%, today the health is 98%.

I fully charged my phone, after leaving it for 2.5 hours, only 93% battery left for doing nothing, no background refresh, Apple Music, Facebook, Instagram were removed, not receiving messages during the time but still draining battery like that...

Now as need to work from home, so I leave it charging all the time, it is really such a pain...

Hello!

My iPhone 11 behaves the same after I've installed iOS 13.6. The battery draining too fast overnight for no reason.

Also when I put it on charging it's getting very hot. These things did not happen before the update.

What should I do? Apple, is this normal?

@poh97, bro your phone OST is better than my device. yesterday i got OST only 50mins. with very very less use. overnight battery lvl drops 40% with not much background activity.. many users having this issue across all devices.

Hi Andy, I can see you might be concerned, however nothing about the battery health numbers you quote should concern you. It is not a linear process, it is an estimate and all phones behave differently.

It's like the Health app - I see people saying "my wife and went on the same journey and it gives us different distances". Yes it would do that, being based on how it jiggles in your pockets. Battery Health is an estimate looking at the voltage compared with what it thinks the new voltage should be.

My own iPhone was purchased 25th March and is now on 97%, my other phone purchased 21 month ago is on 85% and I am happy that is normal.

Battery drain however will depend on many things. The apps you have, the settings and most of all if you have a large iCloud Photo Library. If you do, you should expect a large drain for a few days while thousands of photos get synchronised and in many cases re-analysed for faces, objects and all sorts of stuff Apple think you need.

Me, I use USB and a Mac for my photos and will never change.

iPhone Battery and Performance

having the same issue

i have iphone xsmax after 13.6 i lost my battry life in 3-4 hours Of use

in 8 hours of bed time i lost 15% off my battry charge

restore my phone as new but the problem still alive

Same here... after 13.6 my iphone 11 (purchased this April, with 100% battery health) won't hold a single morning. Basically whatsapp and by lunch no battery. Crazy! It's also overheating...

Ah Apple (sigh)...

No I am just like you, another user.

If you want response from Apple support You can: Contact Apple for support and service - Apple Support 

If you want response from Apple the company I wish you luck.

Why my phone is reducing 7% battery after turning everything off, I have fully check my phone its not faulty and you are taking about many people who will not even realize about this problem because they do not care about it and they dont look into it seriously, if more than 200 users have justifed that battery is draining and heating problem is there so it is there no need to ignore it and no need to let go, will wait for a fix again from Apple, besides this reduction in battery drop i have no problems in my phone.

You’re not alone. My XS Max is running hot and I’m not even using any high demand apps. Screen brightness is also less than 50%. I have also noticed the camera has been sluggish especially when launching from the lock screen.

Hi I’m in France & I experiencing the same problems of overheating and high battery consumption on my 11 Pro Max...

I suspect Apple to « boost » frequencies of the CPU core in order to stay in a good place in CPU benchmarks like Geekbench or Antutu, between its new Androïd rivals like Samsung S20 Ultra....

I definitely regret this update : I was near the swimming pool, under a tree, and my screen began to drop in intensity, because the phone was very hot🥵! It has never happened some days ago with iOS 13.5 in hot days. Not happy !😡

Same thing going on here but instead, I’m on a iPhone 8 and my battery would charge slow, and when it reached around the 90 mark it would stop at a percentage and not go up and lag when I take it out of charge
