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 have same problem on my ip 14 pro. After upgrade to ios 16.1.2, the battery drained badly. Looking at battery usage it said siri used 20%. I turned off siri, then few hours later I checked battery usage again. It says camera took 70% but I did not use camera at all. How come the camera took 70% of battery usage. Apple software updates is awful :(

As of this morning, my phone battery is draining so fast the charger can't even keep up. The power is on, all apps are closed, airplane mode is on and screen is off. Battery still draining faster than the charger can replenish it. iOS 16.11 on iPhone SE 3rd gen.


NOT acceptable Apple. This is a 1 month old phone.

Experience the same problem. Turning off optimized battery kinda works, at least for some degree. Also that I did I close all apps in background and reboot my iPhone. After that, draining while I sleep is almost stops. Pls fix that problem, on iOS 15 I had great battery performance even in my 86% battery health.

I have an iPhone 13 Pro with 91% battery health -- of which the health of the battery dropped from 98% to 91% after the ios 16.1 update. The past few weeks, my phone has been losing 8-12% an hour and running hot with it just sitting there and not much activity. Actually using it for anything that you would want to use a smartphone for drained it even faster. I have both called Apple "customer service" and visited the "Genius" bar and everything checked out and they couldn't find any issues with the battery or the ios. I explained to both that there are known threads out there describing these issues that many are experiencing, but they had no knowledge about it. Not sure what the point of these boards are if Apple doesn't actually review or assist and they leave their customers to fend for themselves. Pretty poor all around service when they won't acknowledge known issues.


Following the advice of someone else on another thread, I disabled contact sync and that seems to have solved the problem. The problems for me seemed to be around syncing the contacts to iCloud, so I turned that feature off for now. If I find the battery drain has continued, I'll update here. Hopefully, ios 16.2 fixes this issue when it is released next week and we can turn contact sync back on. There should be no reason we have to dumb down these smart phones.

I don't think you are going to get ANY Apple support person to say there is a problem with a release of their iOS, or of their hardware, no matter how many people in the support community complain of similar problems. I'm sure anyone that said anything like that without there being an official statement from Apple would lose their job so fast their head would spin. They have FAR too much to lose to have any employee admit to issues with their products. Any statement or admission of such a thing would have to come from Apple corporate.


That said, my phone did this for just one day - they day I upgraded to iOS 16.1.1 As soon as I upgraded to iOS 16.1.2 (or whatever the newest release is) the problem went away. Lucky for me, I upgraded to 16.1.1 late and 16.1.2 came out the next day. It was very clearly a problem with that version of iOS.

Hello. I have a Iphone 14 for 2-3 weeks with 16.0 version and the battery discharged 20% from 100% in one night,with no usage. Yesterday I’ve done your above steps( 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%) + Contact backup deactivated and 100% succes last night (zero % discharge)

I’ll try to activate the contact backup now and see after.

Thanks.

The day after the 16.1.2 update, I started noticing my case getting hot, and the battery would drain about 15% per hour, regardless of whether the phone was being used or not. Before that update, I would typically make it to bedtime without having to charge during the day.


It's maddening that an update can cause the battery to start draining like this. I've heard different people talk about apps that are using 40%-60% of their battery life (mine was the notes app -which wasn't being used). We shouldn't have to start shutting off apps, changing battery optimization settings, or turning off iCloud sync, etc., just because we updated the phone. I've used mine the same way for years with no issues.... until the update to 16.1.2. Apple needs to fix this right away.
