iOS 13.6 overheating and battery drain issues

OK now the mods have deleted the parts of the post that violated the rules...

There is no inbuilt problem with this 13.6 and the drain problem experienced by the few 13.5 users was "fixed" by 13.6.

However it is possible to have a bad update or bad apps.

Always use a mac or pc to do all iphone updates if you possibly can.

So to fix this use a mac or pc to

• Backup
• Restore as NEW device

Before restoring from backup test the phone again with just stock apps.

If you still burn battery suspect the hardware.

I would then build up essential apps from App Store rather than a Restore from backup.

That is definitely not normal, someone in this post suggested to power cycle the phone 2 times to resolve the issue. I have just done it and now getting off from charging, will check to see if it works.

Some websites suggest to restore all settings and claim working. However, this is not a good option for all people like me, as the Apple Pay will also be restored, I am in overseas, it is impossible for me to activate all my cards again unless going back to my home town. My phone is SE 2 which I bought it on the release date not long ago.

Some sites also suggested the Apple Music contributes the issue, so I removed it but then it looks like killing some features on my phone. I suspected Facebook or Instagram apps, so I removed all them, I only use the Web to login but I do not see much difference. It is quite painful for a smart phone not doing that smart need to compromise so much to save some battery life for daily use :(

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.

I’m using iPhone XS and it’s overheating and freezing while playing intense games like PUBG, earlier I didn’t have this issue after updating to ios 13.6 it has fall down on me

PS:Netflix,while watching videos sometimes it’s overheating even with low brightness at night

Fix this fail update ASAP

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.

I also have iphone SE 2 and I have got my phone last week and the battery health is at 100% and the battery life is horrible after updating to IOS 13.6. Yesterday When i slept the phone was at 100% but today the phone came down to 92%. 8% idle battery drain for a brand new phone is not acceptable. Apple should take care of the battery life. I am very disappointed by Apple and apple should fix this in the next update.

Gentlemen, I have the same problem, Iphone XS patient, the battery drops within 3 minutes of use, 1% battery drops. The phone heats up sometimes, I tried everything interesting with the internet and wifi turned off while listening to songs on spotify, the battery works fine. I am currently updating the phone to version 14 IOS beta 4, we will see if it helps. Authorized service said that the phone is ok.

Tried 13.7 and the battery drain went into hyperdrive. Literally. Doing the update took 10 minutes in which time the battery drained 17%. Even plugged in it was actually losing power and didn't manage to charge when plugged in a whole day - dropped to 40% at one point. Overnight it did not recharge either - I had to turn off the optimised battery charging to get it to actually charge, going from 29% to 78%, when normally it would recharge to 100%.

I am trying the icloud hack suggested by MarcBr8 but in that time alone it has dropped 10% just doing the phone restart.

My SE 1st generation is not suffering the same problem but both phones on a recent tourist trip were not performing the same as before - they would not last a day on camera function. I'm afraid I'm seeing the same repeated messages from the experts here implying we the users are at fault but no actual working solutions.

'...I asked him if there is reported battery issues with this update, he said that not aware of...."

Report it to https://www.apple.com/feedback/iphone.html

and they will be made aware.

Delete the apple music app

done

Ah so do I. 6S and 7.

Mine are cool.

What apps are you running to cause that? They should show up in Settings.

Are you able to post the battery usage to compare? You should have the same for iOS13 to compare as a base line.

I am using my iPhone 11 Pro Max and I updated that like 3 days ago. Everything seemed fine in the first day but then the battery performance started getting worse. I have checked in the settings that the battery health is at 100% and I am pretty sure it ain’t my battery’s own problem. It is ridiculous that it legit drops 4% while I only used that for Facebook messenger for less than 10 minutes.

Guess Apple really need to think about what is going on with their developers like every iOS updates are full of bugs. I really miss the good old times like the iOS 6 and iOS 7.
