Battery drain since iOS 15.6 is ridiculous

Same problem on all our Apple products. Did an upgrade on two IPhone 12, one IPhone 11 Pro, and one Iapd Pro 11“ 2 Gen.

All devices updated form 15.5 to 15.6. On each device the battery is running super fast empty. not usable anymore without a powerbank. O; each devices!!

A clean install on one of the IPhone 12, and then a backup from ICloud also didn‘t fix the problem. Apple said this should fix it, but it doesn‘t. Even ‚‚twas getting worst, after update battery health crashes from 100% health to 94% and one day later to 93%. this come is 6 month old!

So big warning, don’t install IOS 15.6.

Apple, please fix this problem, and don’t let us make extra route with fresh installations. It won’t work!

BR.

Lawrence, I reported the issue to Apple. The advice they gave me was the same I got with IOS 14.x battery issue a year ago. Apple made a copy of the Log from my IOS 15.6 installation. Then I have to install a clean/new iOS 15.6 version (no update from 15.5 to 15.6) and then I had to restore from my ICloud Backup. ODU everything with the result, that the battery drain still is remaining 😳😢

same Battery drain issue is still on 4 other devices at my family , where we updated from IOS 15.5 to 15.6. IPad Pro, 2x IPhone 12 an on my IPhone 11pro.

As I said, i did a clean install on my IPhone 11 Pro and my IpdaPro. still the same issue, so I didn’t waste my time to do the same procedure on the IPhone 12 as well. Still waiting for IOS 15.6.1 to get this topic fixed.

Install a clean/new iOS 15.6 AND DON’T INSTALL ANYTHING AT ALL. No apps, no mail accounts, don’t enable iCloud sync. Charge the phone to 100%. Use the phone for a day. Does the battery drain still happen? If it does you have a hardware problem. If it doesn’t one or more of your apps are causing the problem.

Apple has big time messed up with everyone’s Phones with iOS 15.6 update. IPhone 12 Pro Max with iOS 15.5 battery used to last 2 days. No other changes except iOS update to 15.6 and battery doesn’t even last half day.

This squarely is an Apple iOS issue period.

a) This didn’t make sense , on our phones if nothing has changed except iOS update, it’s iOS 15.6 that’s causing issue

b) Everyone here bought iPhones at a minimum $700 and upwards to use it with apps, not to use phones with experimenting one app after the other for nnn days downtime , we users expect the updates not to cause issues

c) @Apple if you think you cannot release good quality tested updates so frequently, please reduce the frequency and provide better quality than quantity

Lesson learnt is to not to update iOS and wait at least one to two releases from now onwards

I am a user, I don't know iOS internals. I don't have to explain that, Apple does.

My battery is ruined.

Take a look on Google, lots and lots of people are complaining about batteries ruined.

And all that Apple says is "its is somebodyelse's fault".

Apple doesn't generally comment at all. They have not, for example, commented in this thread. And, suggesting that the problem with the phone is something other than the most recent update is vastly different that saying "it's the user's fault".

iPhone 6s+.

Battery was ok until I installed first version iOS 15.

Then, immediately, my battery lasted 1/2 of what it did with last version if iOS 14.

Now battery lasts 1/3 or 1/4 of what it did with iOS 14.

Battery health 92%.

I know, it will never be Apple's fault, it will always be our fault.

My Xs Max has 96% battery health, factory original. I’m a light user. I stayed on IOS 14.8 until IOS 15.5 was released. Few days of indexing and all other background activities that I understand, a month later still having awful battery life and my cellular all over the place. Waited two months for IOS 15.6, hoping it will fix my battery issues but with such a disappointment here I am sitting and looking at my iPhone screen watching the battery drain like a timer on a microwave.

I had the battery drain issue as soon as I updated to IOS 15.5 with all of mine and my families devices. But reading this I find it interesting that after the 15.6 update the phone battery is back to normal and working great as well as all other devices except my watch. It worked 1 or 2 days great then now it dies mid day (better than 2-3 hours with the 15.5 update). Wondering if it’s regional some how, as here in Sweden myself, my family and friends battery life issue has been resolved in our phones and iPads but so many others are complaining through out the iso 15 updates at different stages. Interesting….

No, it has never been replaced, it is original, I am a very very very light user.

As I told before, battery was ok until I installed first version iOS 15.

Then, IMMEDIATELY, my battery lasted 1/2 or 1/3 of what it did with last version if iOS 14.

Too sad see battery charge dropping 30% in one day with 10 min of whatsapp and 10 min of a bank app.

Again, it was ok with ios 14, then it has been terrible since first version of ios 15.

I am wondering if Apple engineers testing IOS 15 on older devices, not only focus on the latest and the greatest

Apple’s internal alpha testers test every version on every device that it runs on. In addition, there are over a million beta testers who test new releases for months, and they are distributed among all hardware versions. And you will notice that most of the reports in this thread are from users who are using the “latest and greatest”, so your hypothesis is fatally flawed.

feliperj ~ Light user or not, the original battery in your iPhone 6s Plus would be long overdue for replacement. The long process of applying a major iOS update to an iPhone 6s Plus with an aging, weak battery can be the proverbial "straw that broke the camel's back." Your old battery wouldn't be the first to fail following a long update. Have the battery replaced and then tell us how great the new battery life is.

I started to have the battery drain issue a few months back. I can’t recall which update it was. But I’d have to have my phone on the charger for a few hours mid day & then it would be drained again before bed. I did this update last night & this is the first time in months, I didn’t have to charge my phone all day. It’s almost 11 PM here & I’m still at 43% battery. Im not sure how to even figure out what caused the fix since others seem to have gone in the opposite direction. Apple needs to fix this across the board because a dead phone or one that has to stay plugged in is pretty useless.

Battery health declines, on average, about 1% a month. However, that decline is not always linear. Sometimes, it will stay the same for a couple of months and then drop by a couple of points. Updating the iOS will also cause the battery health to be recalculated. So, if your phone is more than three months old, there is nothing untoward happening.
