iOS 13.6 overheating and battery drain issues

You seem try to alleviate the problem? Considering 13.6 was released just 2 week ago and battery health drop 1% (the first 1% of 2% in total is marginal, so I don’t count), with that speed, how long do you think one must have the battery replaced at 80% health? The expectation by Apple is 2 years or 104 weeks for 20% degradation. Oh, BTW, my 6s was very fine with 13.5.1, but now leaving it overnight, battery level drops more than 30% with no activity, screen off and all connections off. There’s no activity recorded in battery report but the graph shows a stiff fall.

Ok 1 more night with that battery drain issue but I happened to wake up at 2 a.m and the phone is really hot with all connections off. So decided to do a factory reset and install all the apps back manually. Will do the idling test tonight and report tomorrow. Took 2 hours, a real challenge for my patience and memory with all the account info. Definitely don’t want to do it for every other update again.

I too have been having battery issues on my Xr I tried every fix I did a full restore that had no affect i wiped and restored and reinstalled all apps from scratch With no successes in the end the only successful fix I have found and am Sticking with was to run iOS 14 b3. I now have a fully functioning phone and back to charging only once a day.

I’m experiencing the same issue on my 7+ too.

I had my battery replaced by a new one while I was on iOS 13.3 two weeks ago. Everything was fine for a week until I updated to iOS 13.6 a week ago. My phone started Running hot draining the battery very fast that I had to do a restore from iTunes, set it as new and no restore from backup. That didn’t fix the issue. And my battery health went from 100% to 98% in just a week. This is a big issue.

you sure you updated from 13.3?? it should be 13.5 or 13.5.1. in 13.5.1 i had same battery health issue. it dropped from 100 to 97 in few days. now its maintaining at 97%. you try factory reset with no restore from backup. install all fresh. try.. try dfu restore than recovery restore..

My iphone X battery health dropped 3% after updated to iOS 13.6 , and during the day, when I leave the phone in my pocket, I can feel the heat from the phone, and when I checked it again, it has drained out all the battery.

I haven't seen anyone comment on my solution of just powering down your phones two times in a row immediately after unlocking the lock screen. I had all these issues if bad battery drain and overheating plus crazy cellular data usage. Try it it should work. Worked for me. All normal after this trick.

Hello,

I’ve seen the same issue after updating to 13.6. I did not reset any settings. But switched off Apple Music and seems all ok now.

Also I’ve been an iPhone user for around 10 years now and after updating to new IOS version everyone, one can notice some battery drain for initial few days and it will be back to normal. if still persists, visit a store to diagnose. Cheers!

Thanks for the feedback.

Uninstalling Music to get rid of whatever mangled data is causing it then reinstalling has proven benefit to many without the inconvenience of restoring the whole phone to factory.

Forbes has cited this too,

Of course there can be many rogue apps and not all show up in the battery usage.

I have had the overheating problem on 3 of my family iPhones using iOS 13.6 with all apps up to date. In our case it was the Google Maps app that was causing the phone to overheat and drain the battery as described by others. Deleted the app and the iPhones now run cold and battery usage back to normal. I have nothing against the Google Maps but perhaps the current version is doing something it shouldn't. Try this solution for yourselves.

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.

Unfortunately, my iPhone 11 also going heating after update iOS 13.6, I have hard reset but not help.

Now I delete all google apps (maps, translate, youtube, disk) and today is better.

Also, when I get the brightness at 100% iPhone gets a little heating. Now I get brightness at approx 30% and it is fine. Apple must resolve this problem with iOS 13.6.

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.

With no apps running, I have 100% CPU utilization for 3 - 4 minutes after I do a reboot. 13.6 causes my BofA App to timeout. You are going to get poor CPU benchmarking with 100% CPU being used. It’s also what is causing the heat issues. Geekbench shows my CPU performance at half what is normal.

It's high CPU utilization that is causing the heat and battery drain. My phone is 80% - 100% with nothing running except for system stuff. I turned off everything. They are logging my phone activity. They know they have a problem.
