BATTERY DRAIN DRAMATICALLY ON IOS 16.1.1

I purchased the iPhone 14 Pro Max the battery was okay not as good as my previous iPhone 13 Pro Max which was a legend. It’s annoying how my battery has been dramatically draining so fast on my latest iPhone 14 pro max after the iOS 16.1.1 update apple should really fix this we were promised a better battery life which should be an hr better then the 13 pro max not lesser by 5hrs it’s barely lasts through the next day when I used to get 2 days of 13 pro max. Come on apple I’m really considering selling my latest iPhone and get last years one!

iPhone 14 Pro Max, iOS 16

The drain is indeed dramatic.

Dramatic enough to consider moving to another mobile platform.


Thanks appleheadone for finding a workaround.


I guess that the UAT people at Apple rely on actual users to find solutions for what should be the outputs of their jobs. BTW the only reason why I accepted the release is that the phone annoyed me with UX coercion, which eventually left me no choice to upgrade, for fear of being further annoyed. The cost of accepting the coercive demand is having worse product.


Yes agree with others -- this is not acceptable.


Is not the passing of acceptability not a function of the testing team over there in Cupertino? What gives?

Yeah it’s unfortunate that Apple may lose a lot of users over this long drawn out issue, that has no communication on when it will be fixed. Has anyone seen this as a concern from Apple?


I also tried turning OFF my Contacts in iCloud setting and that stopped the draining even more, when paired with the battery optimization work around. So both together seem to make the battery some what close to normal. The 16.1.2 update definitely did NOT fix the battery drain issue.


What a bummer.

Hi everyone, I can’t remember who posted the some sort of a solution, but…it said turn off optimize charging on your phone then use your phone until the battery dies. From there fully charge it back up. I tried this and it semi fixed the issues. Reason I say semi it’s still seems to die faster then before but not as near as what it was prior to trying this.


try it out maybe it will help you too…until Apple decides this battery issue is a major one and have their developers all

over the next update to fix it.


good luck!!

Go to the battery settings & turn off the optimized battery charging, Switch off your iPhones and then turn it back on. Leave it to die then connect it to the charger let it charge from 0 - 100% hopefully it will stop draining I tried doing that and thank God it’s getting back to normal you’ll even notice it on your battery activity. I wish you all the best ! just follow my steps I hope it will get back to normal. If it doesn’t work let’s hope the upcoming updates fixes all the bugs and battery drain issues.


also keep an eye on the screen idle for some reason it’s getting higher then normal
