iOS 13.6 overheating and battery drain issues

Well I didn’t charge my iPhone 7 Plus which I bought almost 4 years ago properly and its battery health level is currently still at 87%.

What I find out is that both iOS 13.6 and iOS 13.6.1 bring deteriorated performance and unusual battery drain to my iPhone 11 Pro Max.

I’ve tried factory restore my iPhone 11 Pro Max but all the same glitches were transferred back. The battery percentage drops every 3 minutes even if I leave it idle. The battery health drops by 1% every 10 days. Wth is Apple doing

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.

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

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.

Those who have battery drain issues, please try to reset last three settings. and also other reset settings if possible. then restart. might help.

Thanks for the heads up!

a grateful user weary of iOS updates that wreak havoc with iPhone performances.... as though it was a kind of planned obsolescence invite.

Or maybe I should buy iPhone 11 Pro instead of this iPhone SE 2nd gen. The size that fits nicely in hand was the main reason of buying but now it’s useless

Looks like an employee of Apple that still trying hard to convince unsatisfied consumer.

Now I’m in complete regret for updating into iOS 13.5.1. when I should just stay on factory iOS.

Meanwhile

Backup .

Restore as new.

restore from backup.

Turn off all background permissions.

Monitor battery usage by app and uninstall any obvious burners.

I wouldn't want a handwarmer until then
