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?

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?

Then my wife's iPhone 11 is having some issue, she bought her phone 3 months before my iPhone SE, we both work from home, charge time and frequency is almost the same, usage is also similar but she did not upgrade to 13.6 and her phone battery health is 100% still while my SE is 98% right after upgrading to 13.6 (99% on the first day and 98% on the second day).

@peter_watt - My iPhone SE is just outside warranty (two years two months old) but battery health "maximum capacity" is 90%. So I don't think battery declines 1% per month as you say - mine has declined at less than half that rate. Also, at 90% capacity, my iPhone should be lasting all day with the generally light workload I give it. I can get maybe five or ten minutes checking emails and its dead. And it was working fine until a couple of weeks ago when I suspect it automatically downloaded iOS 13.6. I have another (work) iPhone 6 which runs 13.5.1 and works fine and the battery lasts all day easily, even though I have to use it now to do much of my personal stuff as well as work stuff. So I turned off automatic download yesterday just in time - it was due to "upgrade" to 13.6 overnight last night.


Do you work for Apple? If not, how can we get a response from Apple on this significant software issue, and an acknowledgement that there is a problem?

...by the way these drain threads have been on the forum since iphones came out. Ditto Android and Blackberry forums.

Re 13.6 it contains essential security patches and has "fixed" the battery problems for some, and "caused" them for others who had no problems on 13.5

The reason being it is not and never has been an inherent problem in iOS, but rather in its implementation on individual phones, or faulty phones.

Meanwhile majority of half a billion iphones are fine. Of they weren't then Forbes would be on Apple's back.

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.

The 13.4/13.5 updates both degraded my iPhone SE and iPhone 7 battery performance, for example:

SE: typically lasted 2-3 days with my use, now about half that

7: typically lasted 2 days with my use, now barely half a day before I've dropped below 50%


13.6 only made it worse.

NONE of the apps had changed, it WAS DEFINITELY the updates that screwed the phones up. After resetting the 7 (due to it being my everyday phone) there was no difference.

I feel the same. After researching some discussion forums and Websites, I actually contacted Apple Support. I downloaded the Apple Support app, chatted with them. The support asked me to run the diagnostic from the iPhone Preference support menu, then he said that no issue with my phone. I asked him if there is reported battery issues with this update, he said that not aware of.


He then suggested me to restore the phone to make sure that not software issue (I could not do it due to Apple Pay and some installed certificates) and provided a link to me asking me to provide some feedback to their developers.


There are not many options, I have uninstalled any suspected apps (Apple Music, Facebook, Instagram, etc.), disabled background refresh, reduced mail sync frequency, disabled any non-essential location / GPS services, disabled any auto updates or backup, reducing the backlight... I have scarified so many useful features to save up some battery for daily use (I need to use Apple Pay, transport and driver license if I need to go out, not many places accepting cash for the moment).


It does not really help, so better wait and hope 13.6.1 or 14 can resolve the issue.
