iOS 13.6 overheating and battery drain issues

I have an iPhone SE 2nd gen and I’ve been experiencing surprisingly hot temperatures and performance issues. I tested it in Geekbench a few days ago and got a CPU score of 1321 and today I got 789. I don’t know if this is because of the later iOS builds . However when using 13.5.1 I got great performance. And long battery life.

Could this be just my iPhone or are others experiencing this as well?

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.

Last time I used Photo Stream it only lasted 30 days then they disappeared from Mac. Photo stream will be phased out one day.

I would open your own thread or do some research because you have thousands of full size photos on an unstable iphone and maybe no full backup unless you are renting 50GB icloud. Best leave this now as we're off topic.

Actually the vast majority of people have no issues with each iOS update.


I have had zero issues with my iPhone X, XS or 11 Pro Max, nor have literally millions of others.


I'm sorry you are having problems, but it's not due to gross incompetence on Apple's part.

That’s very lucky of you. I don’t really know much about those bugs I just learned it from different articles available online. (But I’m ps iOS 11 is a notorious one and that’s why Apple focused on the system performance in iOS 12). I didn’t update my previous iPhone 7 Plus I kept it at iOS 10.3.3 lol tbh I have no problem with my iPhone 11 Pro Max until iOS 13.5.1 bugs and glitches start to happen. All in all iOS ain’t really that bad just I dun feel as nice as those times when iPhone 5 and iPhone 5s were introduced.

I have an iPhone 7 Plus. Since my update to 13.5.1 My phone started unusual overheat even on simple usage. Besides, I lost the click on home bottom and the vibrator as a result. I had to put it on the fridge for few minutes to restore it to normal. I also experienced several restarts for no reason but that happens occasionally.

Is there a way to downgrade to iOS 12?

You explain to me why an update of an iOS would require me to get my device repaired. Why should I have to dole out $100 or more to fix a battery drain issue that is the result of a forced update? Yeah apple said “get it repaired”. A soap dish can say that. This unit is a year and some odd months old, was working perfectly prior and now, immediately after updating iOS, is unusable without being plugged in. Maybe you’re ok with the apple company line, but I’m not. Enjoy.
