Battery drain in iOS 14.7.1

Hi,


Battery drain is happening after updated to iOS 14.7, the percent is jumping from 77% to 71% without almost any use, I am using the iPhone 11 Pro normal and my battery health is still on 100%.


Is anyone experiencing this too?


iPhone 11 Pro, iOS 14

There IS a fix that works, guys. I had battery drain issues after 14.7.1 and now I don’t. First thing you can try: Settings/General/Reset/Reset Network Settings. Then charge it and wait a couple hours. If that doesn’t fix the battery drain, you can connect your iPhone to a Mac (if you have one) and do a system restore via Finder. When that’s complete, set it up as a new phone. If you don’t have a Mac, do an iCloud backup, then go to Settings/General/Reset/Erase all Content and Settings. Set it up as a new phone. Once you’ve set it up as a new phone, if you don’t want to manually redownload your apps and customize your settings, you can restore again from your backup. I don’t think this will reinstall the battery drain “bug.” Give those things a try and let us know if the suggestions did or did not work for you.

Nah, I give up. Seems like every solution helps for a while, but then again phone starts to melt.


What I’ve tried so far during last 2 months:

  • removed all widgets
  • turned off mail fetch/push
  • removed most of apps
  • turned off find my
  • restored via phone restore
  • restored via mac
  • reset network settings
  • turned off screen time (was off, so turned on, turned off)


After every fix I saw that battery becomes ok. But next day all of a sudden I feel that phone is warm, and battery dropped by 20% in an hour, all while standby. Funny enough I have cheap old redmi phone which I use for development, and it lasts a week on standby.


I’ve tried to hook up Xcode and watch activity monitor, but after I connected bug seems missing and I can’t even make my phone warm. Anyway, I don’t even know what to watch, because most of the processes don’t show up at google, or maybe it’s gpu that works hard.

as i said this is standard in apple updates. as soon as update 14.7.1 was released, I read on the forum that the old error with a battery drop, e.g. from 50 to 0% in 5 seconds returned, so for half a year I used the 14.5.1 version on which everything was as it should, but suddenly one day they stopped to run applications using mobile data, I had to install updates ....

I have had the same issue on iphone 6s. I upgraded to 14.7.1 after replacing with a new battery.

2 days ago had got the battery replaced (with a genuine apple battery) at an authorized service center and after that I upgraded to ios 14.7.1


Tried everything:

  • disabled wifi
  • disabled background refresh
  • disabled raise to wake
  • deleted all widgets


Still not resolved. Battery drains out in a few hours without any activity.


Wish I had not upgraded. Also since 14.7.1 is a signed version so cannot downgrade as well. Apple please help!!

Is your iPhone 6S Plus's battery still the original one?


And what's the Maximum Capacity % here?...
