iOS 13.6 overheating and battery drain issues

IOS 13.7 is total crap.

my iphone 11 pro is just 1 month old and the battery can’t sustain for 2-3 hours.

In normal daily use just by sending 5 messages on whatsapp the battery drains by 2%, clicking 3-4 photos and the battery drains by 2-3%.

I am totally frustrated by apple.

while normal use, the phone heats up.

please apple don’t do this...it’s frustrating

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.

I have posted in a previous response resetting the Following settings under general then reset:

location & privacy

then power the phone off and on.

if the problem still persists then reset:

home screen layout

then power the phone off and on

if the problem still persists then reset:

network settings

then power the phone off and on.

hope this resolves your battery and hot iPhone issues. It did for me.

I am not aware of a company line on this. I have not seen any announcements. Even Forbes have nothing to say.

Pure logic says if the phone drops 2% charge every few minutes when totally reset to factory and no cloud set-up, then the phone has a serious battery or hardware problem. Some even showed their battery runs down when turned off and still blame the iOS!!

Im not a tech or a scientist but if a battery gets overloaded or super hot due to high chipset demand then the battery would get overworked and eventually become bad. Correct? I’m not necessarily in agreement with the thought that this is just a hardware problem because so many people are having this same problem across many different chipsets and devices. I believe it has something to do with the iOS looking to sync with iCloud either via privacy & location settings or the general contacts colanders iMessage. But my phone was hotter than **** and losing battery quickly and by turning off and resetting systems I somehow was able to alleviate the problem and have stability now. BTW my battery is somewhat scarred because of this issue it now doesn’t take a full charge the capacity is now less than before this whole thing started.

You may want to try iOS 13.7. On my iPhone SE (1st gen), idling battery drain has reduced to about 5% after 8hours. (on 13.6.1 it was about 20%). Still not as good as it was on 13.5.1, but acceptable.

It's not a "myth" thread.

Since 13.6, I am also getting overheating, bad battery performance, and noticed odd caching issues when switching between apps.

I could, for instance, use safari, switch to calc or notes, then switch back.

Now safari will reload.

Same with other apps that performed fine pre-13.6 that have not been updated.

Wiped device clean using a 2020 iMac, started from scratch. Same result.

Just started happening with two different phones (X and 11 pro) running 13.6.1. The phone runs hot and battery drains like crazy. If you're charging at the same time, it runs hotter. The X actually gave an overheating indication while charging. This looks like a software bug to me. In each case when the battery drains/phone runs hot, there appears to be a "stuck" background task running at nearly 100%. I upgraded and will test with 13.7 to see if it fixes it

"Stop writing" - He has nothing interesting to say. Coming back to the problem, it's just a joke that no one can help. It does not matter if I use the phone in normal mode or in battery saving mode - it still drops 1% after 3 minutes of use ..... . And the authorized service says everything is fine.

Hm...I don't think so.

iPhone 11, old 9 months, battery health on 99%

All apps are closed and no backup refresh (sorry for my bad English) in the back of the iPhone

Off; all locations, Bluetooth

Brightness 1/2 of 1/1

I love British humor but please - don't

No joke intended. If your phone is losing 10% battery in 4 minutes you surely have a serious hardware problem.

I can't think of any rogue app that will do that. But remember some minor app devs are claiming they only had 24 hours notice of ios14 so if I were you I would backup and restore as new to clear out the crud and try again. If it burns like that on vanilla ios14 get it looked at.

I've seen that kind of power drop in two situations:

1) You only have one bar of cellular signal, so the radios are turned up full power to maintain connection with the tower.

There was one office I was working at that had very poor reception - in fact most of the building was "No Service."

When I could keep one bar you could just about watch the battery drop; at full power they use a lot of battery, that's just par for the course.

2) Using navigation apps in areas with poor cell service

Navigation apps alone draw a lot of power to continuously get updates from GPS, but add a poor cell signal and its even worse.

Remedy for navigation in poor cell areas is start the navigation then turn off cellular data. It definitely works with Google maps and Strava, in fact some people turn on airplane mode when out running with Strava to save battery and stop getting messages. You only need internet to preload the maps needed for the journey.

This is strange as the problems started after updating to 13.5.1. I've been to an authorized service center and they say everything is fine and I know it's not.

The strangest thing is that the battery drops by 1% whether I use normal mode or battery saver mode.

And I still don't know how to fix the problem.

I had no problems before 14.

After update it used a lot if battery for a while but I sync'd again with no photos or music while it settled. Now it's fine.

Also got rid of hot apps like Times Radio and moved to using Safari to listen.

Its always a matter of eliminating hot apps and high usage processes like photos til the phone re-indexes spotlight etc.
