IOS update 12.3.1 now Battery draining

Updated to 12.4 and still having the same problems. Set in airplane mode last night and it dropped from 100% to 45% in 7 hours. I've brought it in to be worked on and they say there's nothing wrong. Help

I just happened to check my battery health before this update(12.3.1) and it was 86%, checked it last week it was 75%, checked again today and down to 71%! Dropping steadily since this update!! Definitely related!

12.4 didn't help, apple call support didn't help, resetting all settings didn't help..... will now try erasing everything and restoring from back up over the weekend.... if that doesn't work, then will again erase everything and restore as a new device and post it here again that it didn't help :'(

Then hopefully not but if required, take it to the service center and spend extra on an already super expensive gadget. I think even the service center might not be able to find anything

Had anyone been successful with deggie’s suggestion?

Has anyone been successful at any suggestion?

I have tried everything and continue to have the issue.

I continue to be perplexed by the following battery draining problems that are iOS related on my iPhone X:

-Spotlight search either inoperative or functions with errors. My workaround is to leave the App Store open and search and open apps within it instead of Spotlight. Spotlight drains battery.

-Battery function is normal until and unless I open either or both Safari and Mail

There are now thousands of views on this topic. Multiple models of iPhone are affected.

Really, has anyone found a successful fix that actually returns their device to normal functionality?

If so, please say so.

If your phone is overheating you probably have a hardware problem with your battery or the power IC. You need to click on the Contact Support link at the top right of this page to start the service process.

Yes, I’m having the same problem plus my Wi-Fi button will no long swipe to on. Position.

Hasn’t it been proven that Apple does this every time a new phone is coming out. I’m so upset. I can’t even back up my phone since I can’t get the Wi Fi button to do anything.

My battery is draining so fast. I could go all day and now within an hour it almost dead.

So frustrated!

my old iphone 6 is updated to iOS 12.4 and yesterday the battery health was at 94% and now i checked the battery health and it was at 90%. i only charged the phone once tho

Battery Health is an estimate. It will go up or down slightly depending on a number of factors. And, over time, it will go down. It's supposed to.

Safe to assume by now that APPLE DOESN'T CARE!

adding on to my post from a week ago where no sort of reboot or setting up iPhone as new worked, even Apple Service Center could't figure out a problem after keeping my phone with them for 2 days.

I spent ~$850 to get my iPhone 8 about 15 months ago and the only solution they have is to get it replaced by paying another $500.... the only reason they can give is that there is an internal hardware problem and phone needs to be replaced.....!!

Seriously???? An iPhone 8 is going to cost me $1300+ which wasn't even its launch price... disgraceful!

This thread is about updating to 12.3.1. Is that what you updated to? Have you updated to 12.4? When you checked the battery settings what app/process did it show that used most of your battery overnight?

I think if you had bothered to read the whole thread you'd have realised that

1) most of us only experienced this problem after we updated the OS

2) even after updating the OS to the latest the problem still persist.

3) the 'solution' of updating to the latest OS hasn't worked for most of us

& 4) the 'solution' of 'replacing our battery' isn't an acceptable solution.

Sounds like a last resort. A phone without all the usual apps is not very useful. Even if the test works, a phone should work without requiring a fresh install. It could help but is it worth the pain? Apple just needs to get their act together!

1) Clearly you have not read it, otherwise you would know that common factor is that it happens after the OS update.

2) Apple is aware of it, had you read the threads you would know that many of us have gone down to Apple to bring up the issue. Their excuse is always to change the battery or get a new phone.

3) If you had read the thread as you claim then you would be aware that I have changed my battery before as it was starting to fritz. After the battery change the phone was working fine - until the OS update, when suddenly, as if by magic, the battery drains at an unprecedented rate, it drops from 90% to less than 10% and then suddenly shuts down and refuses to turn back on as if the battery was flat. When I plug in the lightning cable the phone turns back on showing at least 15% and within about 15 minutes it charges back to 70%.

So unless Apple has miraculously and secretly enabled my lightning cable to supercharge my phone I am hard pressed to agree that it's the battery.

4) You say that we fail to consider a third party app, I would say that you assume that it is a third party app. Not everyone updates the apps immediately after the OS change, there are those who do and those who don't. Yet the problem still occurs. if you want to claim its the app, then either the older version is faulty (then regardless of whether we use the latest OS or the previous, the problem would occur), or the newer version is faulty (and would not explain why those of us who are using a version of an app that's not updated are facing the same problem). Either way the common factor here is the OS.

5) There have also been others here who have also said that they reset their phones to factory mode after - ergo, there are no 3rd party apps which can be blamed yet the battery drain still occurs.

The Iphone 6 that I still have? The one which I changed the battery? I tried factory resetting it and loaded only Whatsapp and it still happens. Amazingly my older iOS devices? The ones which are no longer supported by Apple (meaning no more updated OSes), their battery life is still doing fine. No sudden battery drain and shut down.

The common factor amongst the complaints have been that the severe and sudden battery drain occurs after the OS update. It is as if the OS has been designed to figure out how old the phone is and to cause problems so as to encourage us to buy a newer model of phone, something I wouldn't mind if not for the cost.

Just want to point out that my phone is a relatively new iPhone 8 (less than 6 months), so it's not the battery that is in cause. Everything was fine before I applied the 12.3.1 update. I have tried to backup my data to iCloud and restore from backup, as it was suggested on this forum, but the problem is still there. I disabled SIRI and it has helped the battery life a bit, but it is still draining.

Has anyone tried updating to the new 12.4 that was just released? I an normally reluctant to apply updates when they are released, but with the battery problem, I am tempted to update and see if its solves the problem.

yes I tried the 12.4 update via ITunes as soon as it was released (specially with the hope to get rid of this matter) The problem still exists. My XR was barely 6 weeks old when I encountered this problem.

Hey you know what? My phone consumed battery even it was off. Went from 100 to 38% while it was off!! This is seriously crazy!! This 12.3.1 just had killed my phone!!!!!!!! Un-fxxking-believable!!! And Apple deny is their fault!! WTH?!!!
