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.
Actually it even got much worse with 15.2.1 for my SE 2nd gen. Now it survives for 2.5 hours at most, while with 15.2 it lasted for about 4-5 hours. So it looks like Apple didn't really fix anything in iOS but rather just broke it even more. I recommend everyone to stay away from both 15.2 and 15.2.1.
Weird experience with my 6s today. I have like many of you experienced big drops in battery even with no usage and with 15.2.1 it’s even worse.
However the weird experience I mention is this, today my battery was at 47%. I wasn’t looking at my phone for less than an hour and when I did it was at 1%.
I just immediately thought, this is too bizarre so I decided to not charge it until it died. Now it has been many many hours of normal usage including having Twitch on, using Xbox apps, browsing Safari etc and my phone is still going at 1%.
Now I know a video above was actually showing the phones turning off after just a few hours but could there also be a problem with this update where the phones are indicating a low battery when it is absolutely not the case?
Contacted apple support about this yesterday. They recommended a factory reset. I asked if there was any point seeing as over 1000 others on this forum are having the same problems. They wouldn't even entertain that. They just ignored it.
I'm on iOS 15.2.1, iPhone 7 Plus, by the way.
My battery health is at 100% for now. Only bought the 6s in April 2020.
Also just a mention to the thread shared above, my 6s doesn’t really ever get hot at all or like it’s being overworked although I know it’s an older model and just scraped iOS 15 approval and won’t get iOS 16.
These battery drops still seem weird and more like a bug rather than the phone or battery not handling iOS 15 onwards. At least to me.
Frustrating issue for many even on new models which really is unacceptable especially for people who need their IPhone for work purposes.
Hope it improves with future updates for all of you.
EDIT: SORRY! I made mistake and described different version of iOS (which is not allowed to be mentioned explicitly here) in the first sentence. The rest of my text concerns my experiences with 15.2.1 properly.
Very strange. 15.2.1 is just security update to fix terrible bug in macOS Safari / iOS WebKit. My phones behave exactly as terrible as before upgrade. No changes noticed - both for 12 mini and SE 1st gen (which is smaller equivalent of 6s).
I had never problems with upgrades but do clean installs/configuration once in a while - just to be on the safe side (to avoid some side effects of upgrades). Maybe this time it's just coincidence and it's great time to make hard reset? Just thinking.
I have to be honest and tell what I found was very fine lint probably from my pocket had been packed deep inside the charging port on my iPhone SE 2020. I was able to carefully remove it with a sewing needle and blowing the loosened particles away as I went. My previous iPhone SE 2012 lasted almost 9 years before the battery wouldn’t even hold a charge and I used a Catalyst case for drop protection, so purchased another from Catalyst for my new iPhone but their new version didn’t have the small rubber port plug so lint was able to accumulate…
I upgraded to 15.3 after solving this issue anyway, in hopes that I might find success in Airdropping files from my Mac to my iPhone and iPad, to no avail, it seems a Monterey 12.1 update issue that prevents my mini from sending files using Airdrop, conversely I am able to receive Airdrops from my iPhone and iPad to my Mac mini 2014.
When I right click on any file or photo in MacOS 12.1 Monterey I can select share then Airdrop and a pop up shows either my iPhone or iPad, (previously in MacOS 12.0.1 both would show) but then clicking on my device nothing happens.
I'm having the same issue. iP 12 Pro Max (which I got a year ago) and recently updated iOS 15.2.1. The overheating/dimming of my screen started yesterday. Happened again today. I had turned up the brightness to 100% during my lunch break. Took off wifi (was on 5G), and was using Safari and watching a few videos. Battery Health is at 91%. I've tried rebooting and no help. It's like it suddenly has a mind of it's own.
WTH Apple?!?! Please fix ASAP with another update!!
1070 people on here with all different models of iPhone, all having similar problems and still no acknowledgement from apple. I have yet to meet someone who has updated to iOS 15 and has anything good to say about it.

Although Apple administers these communities, that doesn't include reading each of thousands of daily posts for possible feedback. However, Apple will "read all feedback carefully" here:

Yes me too, i feel it drained faster than 15.1.1. Any solution?

on my first generation ipone se, i still see big battery drain during the night in focus mode with 15.2 upgrade , upto 60% in 8 hours (battery condition is still at 84%)
so i did the battery discharge check, charged to 100% en shutdown for 8 hours.
on re-start first shows 99% and than a rapid decrease to 88%
Specifically when using hotspot through WiFi, after the 15.2 iOS update. Battery drops at an accelerated rate like 15% in half an hour. Honestly it’s absurd! ( iPhone 11)
