After 12.0.1 update battery drain is high

Same issue on iPhone 6, dropping at 2% per minute just with the home screen open. In sleep mode, also an unusual drop.

If it helps anyone, I got a slight improvement by turning off the "Screen Time" feature (Settings > Screen Time > down below "Disable"). It didn't last too long in my case, but some people are reporting it as a fix.

It's NOT how I configured my phone, it's NOT the age of the battery, it's NOT the indexing after the update (enough time passed, and the other updates don't behave like this). It just worked fine on 12.0 and the only thing that's changed is the update.

It't the same thing they did with iOS 11.4, which had me carry my charger around for several months.

I had exactly the same problem as everyone here: iPhone 6; Apple replaced battery four months ago; worked ok until a couple of weeks ago; battery dropping quickly; battery health showing 100%; need to recharge permanently.

Had switched off everything I could - to the point where I no longer had a smart phone!, but the one thing I hadn’t done was disable Screen Time. Can’t believe it, but seems to be working perfectly now. Only :) lost 5% in last two hours. Basically as perfect as it used to be.

Thank you yulius123!

I performed several hard reboots (home button + power) and although my battery life is still not as good as before 12.0.1, it is much improved vs after the update

After months of poor battery and having to charge twice a day I have found that running the latest beta 12.2 fixed my issue. I’m back to charging every other day the same as in iOS 11. I had previously tried everything possible including running the phone completely stock with no apps etc and could not get the phone to last more than 8 hours in standby. Now it’s better than ever.

I ended up taking my phone to the Apple store when it wouldn't hold a charge for more than 2 hrs and I was traveling, without ability to plug in constantly. I waited for 2 hrs as a walk-in for the "genius bar" service. After another hour the geniuses determined the battery needed to be replaced which I approved. While attempting to replace the battery during the following hour the geniuses ripped a cable and were thus apparently unable to replace the battery. Geniuses said I needed a new phone, it was now not fixable. Since I have a year old SE, which apparently they have stopped making, this store and hardly any others had it in stock. I had to go to a different store far away to get the new phone and transfer everything over from an iCloud backup that I had to create. Overall this experience took almost 2 days and 3 store visits in person to deal with. So that was a lot of lost work time, on a business trip, where I really needed my phone.

So, in summary the upgrade ruined my battery somehow that was not able to be explained, Apple repair then ruined the entire phone, I now have a new replacement phone that is given to me as an already obsolete device, but (knock on wood) for now at least, works fine with the new iOs 12.0.1. We'll see how long this one lasts.

I'm glad to hear that Knobby888 and Plannergirl found a solution to their problem, and I hope it stays that way for them both. The problem is far from resolved for me, however. I installed iOS software proposed by them in hopes of seeing a miraculous fix all of a sudden (after all the other prescribed miracle fixes that have miserably failed); and sadly, the problem persists.

I had 100% charge, surfed one website for no more than two full minutes, only to be down to 94% with a fire-hot battery once again.

No miracle cure here, folks. Back to the other magic beans, teas, pills, and elixirs!

But what we really should be doing, friends, is all of us scheduling appointments with Genius Bars around the nation, and all of us demanding that this problem be resolved, and not quit going until they either give us free working phones or fix this nightmare they created!! Flood Apple with THEIR problem.

I'm having the exact same problem. Was running great with the 12.0 upgrade and now after the 12.0.1 my battery is dropping equally fast. Maybe 4 hrs at best. It's not the settings, it's the update.

I also have this problem. I purchased a new battery for my iphone 6s in February 2018. The battery health is at 97%. Ever since I upgraded ios to version 12.0.1 my battery drains very quickly, even when I’m not using it. I made sure my location settings are only on when an app is in use. I close most apps when I’m not using them. I dimmed the screen. I have very few notifications enabled. I disabled background app refresh. I store the phone upside down when not using it, but the battery is still draining at a ridiculous rate. I barely use the phone anymore unless I have to and don’t go anywhere without a charging cable. I just spent over 30 minutes on a chat line with apple support. She verified my battery health is good and recommended to backup and reset my device. That is not a solution! I urge anyone in this situation to make a formal complaint to apple. This is the link to make the complaint. Feedback - iPhone - Apple

I just updated 12.0 to 12.1.2 without reviewing on internet about battery issues. My battery health is 100% and normal user that isn’t playing game. I found that 12.1.2 is absolutely bug in battery life which drops dramatically from 100% to 50% just few hours.

I called to Apple contact and they replied “this is normal phenomenons after updating iOS. He says there is some application or setting which will update in background and it will be fixed just a few days later”. I don’t like his way of answer on battery issues. I never experienced such battery problem before.

They checked my battery and battery is in good condition. So what’s the problem in iOS 12.1.2 . Being Absolutely wasted phone!!!!

For what it's worth, the screen time setting has always been disabled for me and i've had dismal battery performance. I just don't want anyone to get their hopes up that this would be a solution.

I thought, how about making the phone completely useless and putting in airplane mode? Would that save some battery?

Nope.

I put it in airplane mode, then turned the screen on and set auto-lock to never so I could watch the battery without touching the phone.

Here are the percentages and the time:

69% at 2:04

68% at 2:06

67% at 2:08

66% at 2:10

65% at 2:12

64% at 2:14

63% at 2:16

62% at 2:18

61% at 2:19

60% at 2:21

59% at 2:23

58% at 2:25

that's an 11% drop in 20 minutes in airplane mode with bluetooth off and all apps closed, with the exception of the settings screen.

On a full charge, that's 3 hours of airplane mode with the settings screen on. Whoo hoo!

I googled iphone 6 standby time

and one of the answers was: 11 hours of video playback

For those wondering, how old is my battery? It's a month old. Battery health says 100%.

Have you even checked to see if your battery is consumed, defective, or if say a single app is consuming then entire battery ?

I have read that article and adjusted settings to maximizer performance. Battery was fine pre-12.0/12.0.1, after installing both of these it lasts about 4 hours. I used to be able to use it all day. Upgrades should upgrade performance, not significantly downgrade it. Very annoying when we are all too busy already to have to contact support for what was supposed to be an upgrade.

I have the same problem with my 6S since the 12.0.1 update too. Battery drains so quick that I’m now charging 3 times a day. Previous to the update I was getting a full day. I can actually see the battery level draining in huge chunks over very short periods of time (upto 20% a minute) just from browsing the web and with my screen brightness turned right down. Once it reaches 1% it apppears to last a lot longer than you would expect for the last remaining 1%. There is definitely an issue with apples latest update. Come on Apple hold ya hands up and get it sorted.

I think, today everybody knows, that there is a bug in iOS 12.0.1. I have of course the same problem as a lot of people (may be all users with older iPhones than 8 or X). I have iPhone 6S.

The question is, if apple did it purposely, or it is really a bug. In this last update, they fix some problems with battery recharging of the latest iPhones, as I have read. It's possible, they fix the "long battery life at older models" at the same time 😀

When I was iOS 12, my battery holds for 2 days (I am not at facebook all the day, ok?).

As I upgrade to 12.0.1, my battery holds for less than 1 day! I bought the new battery, and it holds for one day (from 8 AM to 11 PM).

My wife has iPhone6 (not S) and she has iOS 12, her batt holds longer than my new batt!

What's wrong with apple?

I am planning to buy the new XR model. But, I will wait, until this issue will be solved.

If it doesn't, I completely leave iPhone and go to Xiaomi, or another better and cheaper choice...
