IOS 16.1.1 Iphone Battery Drain

forever-the-luddite Said:

"IOS 16.1.1 Iphone Battery Drain: My Iphone 13 Pro Max battery drains much faster after IOS 16.1.1. It was already draining faster after earlier IOS 16 iterations but it’s much worse now with the latest update. Is anyone else having this issue? Why is IOS 16 so problematic for so many Iphones?"

If it means anything. My phone started to eat battery. My phone (14 Pro Max) was draining with nothing running and the absolute minimal usage. I tested it and made sure everything was turned off, Siri, background app refresh, brightness, you name it, it was off.

The genius bar ran tests last Wednesday, stated something is wrong with it and haven't gotten it back yet. Prior to that I was getting around 4 days per full charge. I updated to 16.1.2 and with no obvious change. Its extremely frustrating as Apple provides no real updates on what is going on nor when I will have it back. I expected more from them.

"Steps to Reproduce: Ran Mobile diagnostics

Ran battery usage diagnostics 

Viewed battery life in diagnostics, there is a sharp noticeable decline in battery life even when device is not actively in use

Viewed settings such as Always on display, background app refresh and toggled all off 

Customer states they already restored device using iTunes and set up as new at home"

Click on the Last 24 hrs button beneath the Battery Health & Charging, take a screenshot of that page and post it. Then tap on Battery Health & Charging, take a screenshot of that page and post it also.

How long ago did you update to iOS 16.1.1?

It seems that I'm responding to 2 different people here. The screenshots that I got from the original poster, it seems the the graphing of the battery match the times and heavier usage, including the fact that Firefox is using 77% of the battery. You may need to watch that to see if it is using more than normal battery. 77% is a lot, but it seems that you are using it a lot looking at the screen time. Is there anything else using a high battery percentage?

I've been through all of this myself after upgrading my iPhone 12 Pro to iOS 16.1. The later point releases didn't make things any better. After a quite a long dialogue with Apple Support, I ended up restoring my iPhone to factory settings. Since then the battery life has recovered to its previous performance.

A quick warning if you're thinking of trying this: make sure you've got everything backed up to your Mac or PC, and also to iCloud. I couldn't restore my iPhone data and settings from my PC, but I was able to restore most of my settings from iCloud. I had some trouble getting my music restored, and Mail was unhappy for a couple of days but seems to have started working again now. It's also worth checking that apps like WhatsApp are also backed up to iCloud before proceeding.

Yes, 6.1.1 caused more battery drain as we’ve all discovered, but that’s because Apple added and turned on deeper settings for tracking and other battery activities. Once I dig deep into all of the settings and turned off a ton of things that I do t need (and neither do most), my drain stopped. No joke. You have to go into the general settings and other s to turn off what the last update turned on. That fixed it for me, but you have to patiently dig. I did mine two weeks ago and can’t recall everything that I turned off but I will note, that I didn’t have to turn off anything that I used or felt I needed for the drain to stop. It was things I had never heard of and they haven’t cause any adverse affects to my phone. Good luck hunting.

I may have spoken too soon. I noticed battery life was poor again today. I checked which apps had been using the most power, and Siri was top of the list (26%) even though I've disabled Listen for "Hey Siri", and hadn't been using Siri through the day anyway. This is similar to the problems I saw previously.

I've disabled Siri for the time being (this means I can't use CarPlay though).

Same exact phone (iPhone 13 Pro Max) & same problem! iOS is so buggy!
