BATTERY DRAIN DRAMATICALLY ON IOS 16.1.1

Have you restarted the phone since the update? You might also try a Forced Restart, no guarantee but worth a try...

The last update killed my battery! - Apple Community

Apple software do such a sloopy work these days , not only modern ios full of bugs , apple still couldn’t figure out how to get better battery 🔋 with every update

and lastly i wouldnt ever upgrade to ios 17 whenever it comes because apple has a history of intentionally make iphone slower with every update and force people to buy new device , fyi apple your greed will never be satisfied no matter how many trillions you get every passing year

I didnt buy apple because it better i only bought it as status brand , motorola tenth of price does better job than this sloppy iphone 13

The battery drain on iPhone 14 pro max is significant. Earlier I used to get a full day and over night and next day till I finish my morning workout. Now I need to put it on charge in the night. iOS 16.1.1 has surely messed up. Hopefully apple helps fix this.

I've tried restarting, force restarting as suggested in some forums.

I have the same for iPhone 13 Pro. Battery was fine before the update, drains like mad after it. Doesn't even last a full day.

Completed iOS 16.1.1 update. Very noticeable rapid battery drain noticed immediately on my iPhone 11. Not great.

I tried all suggested work arounds - force restart, restart etc. but no improvement. Seems like Apple's QA ain't focussed on making sure the releases are good. Can accept some minor bugs.. but battery drain isn't necessarily minor.

Here it is 14% drain overnight with no screen time. This is totally unacceptable from Apple to keep mum on the mess iOS 16.1.1 has created.

12 mini here. IOS 16 battery was good but after the 16.1.1 update battery drains dramatically. Furthermore, during the call when the phone on my cheek, I can not volume up or down. I need to remove my phone from my cheek to volume up or down the call voice. What happened Apple?

I am also facing battery drain in my iPhone 11 I have also try force restart

but no any changes

Same problem for me on my iPad Pro 11" 3rd Gen.

Since Sunday, it loses a solid 2%/h just by sitting there connected via WiFi.

Display is off, and I didn't touch it after the soft reset.

I don't think it's a hardware problem but just a bug in 16.1.1.

the same thing happened with my iphone, is this an ios or hardware error, does anyone know what the problem is?

ios 15.7.1

iphone 7+

Today, for the first time, I am thinking of replacing my apple with an android device.Every update is a problem with the battery.I don't know why you do this to people who have been loyal to you for 13 years.I've been using an iPhone since 3Gs, but I think that this iPhone 12 Mini will be my last iPhone even if I wanted to buy a 14 Pro.New update should solve the problem, but when you have Apple with a new update, you get a new problem.Apple I think it's time to say goodbye.

Same with my iPhone 13 Pro, it’s so noticeable, they should release an emergency update to fix it as fast as posible!
