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.
1 hour and 30 minutes os screen time at this moment and i have 61% of battery (last charged to 90% yesterday at 10pm and i don’t used the phone).
there is a problem with this update.

my iphone 7 . after update ios to 15.2 . always battery drain and sometime shutdown or restart .
please repair this bug .
thanks .
Factory reset does absolutely nothing. It is a very common recommendation from Apple and it almost certainly brings back the issues. The issue is iOS 15 and iOS 15 alone. No ‘if’s and buts’ about it…
Yes, it was replaced at Best Buy by Apple’s certified service technicians. It’s not worth saving $10 to have someone else replace it.
Installed 15.2 on 12.18.21 on my 7 plus. Battery soon drained and would not charge. CarPlay did not work properly in my 2020 Bolt. Battery charged yesterday after a lot of frustration. Hoping CarPlay will work tomorrow.

It's been 5 days since my phone updated to 15.2. I don't know what could have happened over 72 hours to fix the issue, but in reality it gets only worse every day. 5 days after the update, and my phone gets from 100% to 0% in 5-6 hours even if I am not using it at all.

ali83iraq ~ Was the replacement done by Apple or Apple Authorized Service Provider, or approved Independent Repair Provider?...

I have noticed much better battery life since updating to iOS 15.2. I have an iPhone 6sPlus and have gone from having to recharge every 12-15 hours under iOS 14 and earlier versions of iOS 15 to recharging every 24 hours under 15.2. I don’t think I have changed much in the way of settings or usage since upgrading.

Funny, for me it's the other way around. I used to recharge my iPhone 12 Mini every 24+ hours, now with 15.1 and 15.2 I recharge it every 12 hours. Frustrating. I tried resetting and even erasing my phone, nothing helped.
Can anyone tell me what the problem is? It’s been like this since iOS 14.6 and my screen off time has consistently been high even though I check my apps and nothing is using a lot of background activity. It’s gotten so bad to the point that my phone drains by the minute sometimes. I have the 12 pro max that is barely a year old and it should not be having this many problems. At one point this was a 2 day 14-16 hour phone with heavy use. Now it’s barely a 7 hour phone. Thanks apple!!!!!!
Perhaps next time I will just have to upgrade to a better model instead of going for a 7 or 8 ... but just pointing out that many 100s of people seem to be experiencing a very weird high drain after 15 / 15.1 / 15.2 where it was ok with 14.
Since I have last update ios 15.2 ,
I see drastic changes in my battery life for my iPhone 12 , Before the update I used to have very good battery life and I can feel my battery is draining after 15.2 update..!
May be apple wanted that …?
