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

I solved this! The above ideas got me thinking- I turned off Wi-Fi, and kept an eye on cellular data usage per app for a few days.


Turns out the notes app was using 100–200MB/day even though I wasn’t using the app or adding/removing notes. Turning off cellular data for that app greatly improved battery (unless I was on Wi-Fi), but didn’t fix the root cause.


I went through my notes manually and deleted large notes that contained lots of photos or other attachments, which I suspect were having trouble syncing up to iCloud, as I wasn’t willing to turn off iCloud sync. Deleting enough notes cost cellular data usage to drop to almost 0 again - fixing the issue and battery life returned to normal.


Hope this helps others…

Guys 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

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!!

Fortunately, for me, it appears that 16.2 has “resolved” the problem.


I can’t help but feel like I’ve been gaslighted by Apple though. So they create an update that makes you use 100% more battery with no changes to your usage pattern, everyone throws a fit, so then they put out the next update where in the background now you’re only using 20 to 30% more battery power for nothing. Which was probably the intent in the first place, to push additional sales of new phones from people who assume that their phone is messed up for the battery is not working properly.


Since I’ve updated to 16.2 I have not had any overheating that I was having before, or the level of intense battery drain that I was experiencing from the previous update.


hopefully the update will fix it for others as well.

Went to my Genius appointment. He of course ran a diagnostic test and of course all systems came back operating as they should be. I was told to restore to factory settings. I'm currently in the process of doing this. My iPhone is backing up from iCloud as i type this. After informing the Apple employee that I have almost nothing backing up to iCloud and have every possible setting to the off position (that could possibly cause increased battery drain) and no background app automatically refreshing, It was recommended to add the Apple protection care plan before the 60 days expires. So I did that while I was at Apple. Someone from Apple is supposed to call me on Wednesday late morning to followup if my situation improved after the restore process. I should know by the end of the day tomorrow if there is any improvement. I will report back.
