IOS 15 iPhone 12 pro - battery drain

When you upgrade to a new iOS you will find that many apps will update over the days following the launch as updates are released. It's a symptom of a large number of app updates for the release of the new iOS.

It will settle down after a few days.

Hello again ~ Great to hear back but not under current circumstances. Try this:

Close an app on your iPhone or iPod touch - Apple Support

If not help there close all apps and force restart:

Close an app on your iPhone or iPod touch - Apple Support

If still a problem take it in for a checkup:

Genius Bar Reservation and Apple Support Options

If you have to take it in:

Get your iPhone, iPad, or iPod touch ready for service - Apple ...

I would be happy to hear back from you if you have to take it in to Apple. Hang in there:)

I have the same issue too.

I’d manually update all apps in AppStore, so there is not the issue of background updates.

the full drainage took about 10 hours with no usage, with energy saving turned on or off.

I already disabled background checks practically for all apps, but without any success.

I had this on a 12 mini after upgrading to iOS 15.1. Battery would drain to about 20-30% every day with App Store showing as the culprit. Multiple reboots did not fix it. Automatic app updates are turned off, so that was obviously not it.

I did a Backup/Erase/Restore cycle yesterday and that does appear to have fixed it. 3pm and I'm still at 90% today.

Two things which helped considerably: 1) remove News widget, 2) turn off website tinting for Safari. It has pretty much stopped the battery drain. Hopefully this will keep things rolling until an update comes along with a true fix. I do miss the News widget, but I'd rather have juice!

Hi

When I bought my iPhone 12 Pro back in 2020, it came with iOS 14 and had the exact same problem until the fix was released with iOS 14.2.

I have upgraded to iOS 15.1 and the issue is back again.

it drains so fast with very limited app usage.

The reason for this battery drain back in 2020 was my network provider O2, I decided to switch the SIM card to EE and the battery drain stopped.

Funny enough I ran the same test again yesterday and the battery drain stopped.

If anyone has run a similar test then please share your results.
