iOS 13.5.1 battery drain

My phone was perfectly fine, no problems at all in all this years, not until iOS 13.5.1

I dont get your point of defend 13.5.1 even if theres is a plenty of users complaining about this matter, and you are on deny telling us is not the update and the problems are our phones, and even suggesting sell our phones, and if you look around there are users using XR and 11 and iPads reporting the same problem with 13.5.1!!...you are funny

I'm not sure why you're suggesting this was some aggressive response--I'm a systems engineer and was simply curious about your reference to OTAs potentailly being the issue. Technically speaking, the binary being downloaded is checksumed and once downloaded, it is verified before the setup executes. I have been using Macs and "I" devices for many years and almost never use a tether as OTAs have been pretty solid, albeit a retry required here and there when network connectivity is bad. Anyway, have a nice day.

"I think you are right! Also, ‘if you’ve got a problem, buy a new one’ !!!!!!"

Yes, that's what I usually do with each minor iOS upgrade, but unfortunately this week I had to buy a new TV. I will postpone buying a new one till next week, as it is _clearly_ a hardware issue on all of my iDevices :)

My wife has a 6S with wifi on all the time and a number of apps like whatsapp, Mail and banking, cellular data is off.

It took 13.5.1 OTA on day one of the update.

Battery is 85% max capacity.

We charge it every 4 to 5 days which is the best smartphone standby we ever enjoyed.

Doesnt help you but it suggests other than a universal OS bug, eg a damaged battery

The following shows level after 3.5 days so it could last another 3

Thst's my wife's phone. Just illustrating the background drain can be 6-7 days which contrasts with some of the reports.

My own iphone behaves the same on 13.5.1 as it did on 13.0 onwards. Battery usage matches heavy phone usage.

EXCEPT I installed a Barometer app yesterday . See the light blue background usage. That app is going NOW!

Pity, it was a good one.

Im in the same boat - upgraded my iPhone7 for a first attempt before I do our newer iPhones and I've lost cellular network (just searches all the time) runs very very hot and discharges at a rapid rate - Im sure its doing some damage when it gets that hot. I think we need Apple to help us with an easy way to go back IOS versions so we can get out of the trouble were in while they fix the BUGS please!

"...Please stop hijacking the forum thread by telling us to turn this setting off or uninstall that app. .."

What would you suggest?

PS you have a strange grasp of the meaning of Hijacking. Giving advice well intended is not hijacking just because you do not accept it. My advice is the only advice anyone has given on the subject. The alternative is wait for 13.5.x

Just updated my iPhone XR to 13.5.1 last night and it ran super hot in standby mode all day today even after an additional reboot and the battery was almost dead in a matter of hours even with no apps open and limited usage. I can’t make heads or tails of the battery analysis under settings but it says the photos app was open for 1 minute in the background but used 26% battery! I hope this is addressed soon before it possibly causes damage.

Also, there is something else I have noticed since I updated to 13.5.1; my iPad used to turn on as soon as I plugged the charger, after the update that behaviour is gone, I have to manually do it.

By the way, yesterday I left my iPad fully charged at 100% and overnight it went to 58%, all apps closed and fully turned off.

Hope Apple releases a fix soon, I don't see how a mobile device should be plugged all day long to be used, the practicality gets lost.

And the strange thing about the “Buienradar”... I don’t know if you understand Dutch? It’s an app to warn me when a shower comes up.

I can do a forced shut down, but he still gives me a message when he needs to, although no background activity.

And indeed, while running in the background, the battery consumption isn’t very high.

When iCulture does the same, the battery drains much quicker.

Conclusion: I will terminate my research to solve this. Hopefully it’s fixed with the 13.6 release. Maybe I can try the 13.6 bèta if I have some spare time. Don’t know for now.

Well, my iPad is just over 1 year old and it is having the same battery drain issue since I updated to 13.5.1; I hope we get a fix soon, I don't want to be locking for an AC outlet all day long when I bought device that is supposed to be mobile, not tethered.

I have to say that over the past 24 hours my phone has miraculously started to get better. As the other person posted above it’s been happening in increments and now the battery is not draining as fast. I would say I’m about 70% of the way back to how things were. But I just checked and for some reason Siri is still active and using about 27% of my battery even though I have it disabled across-the-board. The other day it was using 45% even though it was off

Same here iOS 13.5.1 battery drain just with background stuff running. It even went to zero and **** down this morning immediately after the software update, when I unplugged it from

charger. Apple needs to fix this!!

I have noticed a major battery drain after the update. My iphone 7 gets too hot while performing normal tasks like facebook scrolling or in that case with other social media apps too. Battery drain while usage is crazy. 5% drain in almost 7-8 minutes of time.

I'm a developer, and I can confirm that this problem is from iOS itself, not about any app else.

No matter what you did, factory reset, reboot, reinstall all the apps, it's just not working.

And it's absolutely not about any hardware issue.

iOS tends to stop running anything if the app is in the background.

That's why it needs a background permission.

Before Apple introduced the BGScheduleTask, there's no long running task can be running in the background.

We only have a few seconds(maybe 30s? never use it before.) to do the jobs.

If you never explicitly tell iOS you need to run background tasks, then all of your thread will be stopped after 3 seconds.

Nothing will be running in the background.

If so, why is there so many apps draining battery?

Just like my app, I didn't do any background tasks at all, but it still shows that my app is running in the background for several hours, that's insane.

To figure it out, I put a `print` in a looper on a worker thread. Guess what? It stopped printing after 3 seconds.

So nothing is really running in the background.

But the weird thing is that it did show some activities in the Time Profiler.

It needs time to look into it.

And Apple should be responsible for this issue.

I also tried the way iCulture did. But the traitCollectionDidChange never get called in my case.
