Is anyone experiencing battery drain since updating to iOS 15.2? If so, any tips for what to do about it? I just updated this morning. Thanks!
iPhone 12 Pro Max
As posted in the 15.1 battery drain thread, some of the fixes that I found might help with 15.2 as well. I'm talking about drain that persists for more than the 1-3 days after an update while Spotlight is indexing. I had my iPhone 13 Pro Max and iPad Mini 6 BOTH draining enough to run dry in 20 hours of standby, and fixed it completely, so I'm still on 15.1 with no issues..
1) Turn off Apple News Widget on your Home Screen if you have it configured. I had seen that Apple News was using a lot of battery in "Settings > Battery" and I wasn't using it. Turning off background app refresh made no difference in battery use and drain in the background. Then I discovered the widget hiding on the screen to the left of the Home Screen that has my app icons, and turned it off. That reduced my drain from 5-7% per hour to only 3-5% per hour. I also turned off most of the other widgets except Calendar, Reminders, and Battery level for bluetooth accessories (watch, and AirPods).
2) I had my iPhone 13 Pro Max and iPad Mini 6 paired with my iMac and MacBook 16", and had "show this iPad/iPhone when connected with WiFi" turned on. I "Reset Network Settings" which broke this pairing, and COMPLETELY solved my battery drain issue. I was later able to plug my devices back into my iMac and pair/Trust them, but I made sure to turn OFF "show this iPad/iPhone when connected with WiFi" when I Trusted them, and the drain has not come back.
Apparently the WiFi network connection between iDevice and Macintosh computer maybe has the iDevice phoning home continuously in 15.1, even when you are not on the home, and this system resource is still draining the battery regardless of low power mode or not. But my best guess is that when the iDevice is NOT looking out for the computer constantly, with "show this device on wifi", then the drain goes away completely FOR ME. This might not be your problem.
My iPhone 7 Plus is also much warmer than usual since the update to iOS 15.2.1
Totally agree. I've tried that reset nonsense for other problems before and it does absolutely nothing. It's more of a fob off from apple.
Even worse after 5.2.1. The battery behaves as though my phone is years old instead of months old . All background app refresh is off an location very limited . No help
They tend to do that a lot when it comes to things like this. Remember 'batterygate'?
I'm not sure if it makes sense to keep posting that link for submitting feedback to Apple as there is no option to specify iOS 15.2 there, so no one is going to process our reports properly anyway.
No mention of the battery problem in iOS 15.3 release notes.
I installed 15.3 yesterday, I am not sure if it got even worse with that update, but for sure it didn't get any better. Still same crazy battery drain.
Facing the same issue on my 11 pro and following this thread actively for a potential solution. No luck so far even with the 15.3 update.
Thank you, just e-mailed them.
I have an iPhone 13 Pro Max and was working beautifully until I updated software to 15.2. I always play Words with Friends and have it charging while playing. With 15.2 battery drains even though charging while playing Words. Please fix the problem with next update!!!

raffeph ~ We can't "fix the problem with next update" – because we're just users like yourself. Ask Apple to fix it here:

But it was 15.1 that kicked off many of the recent complaints about battery drain. Obviously they haven’t issued a fix yet in 15.2. Maybe it will arrive in a future iteration.
But please…… anyone having these problems, please report directly to Apple Feedback. Another user has kindly provided a link elsewhere on this thread, or you can simply Google it.
Apple is not reading these user forums.
No, it was actually iPhone 2 and the inclusion of 3rd party app that kicked off many of the complaints about battery drain. Prior to the inclusion of the App Store Apple could carefully control what was running on the iPhone since it was available only on one cell provider and only AJAX apps were available aside from ones included with the OS. Every update since then has resulted in battery drain issues from someone. And there is no feasible means to test every possible combination of iPhone configuration.
yeah i got the update about a week ago, but i didn't get a battery effect until today. so i left for a class i have every monday from 7-8, and the battery drained like 10% in 1.5 hours. It was normal for the ENTIRE day at school (keep in mind that my school has bad wifi, so it drains it faster than at home) all the way until the evening, and then that happened while my battery was at home. the strange thing is, it drained more with no background activity at all than when i actually had my screen on, as you can see the usage from 6-7 in the first pic vs 7-8 in the second pic. my questions are: why did it just happen now, AKA a week after the update, why did it happen at home with A) better wifi AND service than at school, and B) NO background activity whatsoever??? and why did it just happen from 7-8? it was normal for the entire **** day, even after school! I was planning on enjoying a movie on it all throughout my class 😭
Yes u r right i am usinh The same apps and same settings which i was using before the update but after the update the battery is draining very fast ..plz release another ota update to fix this as soon as possible,
