IOS update 12.3.1 now Battery draining

Here’s something I recently discovered on mine. Even though I don’t have an Apple TV my device always looks for a one under screen mirroring. And couldn’t find a method to disable that. Wonder if it’s a cause for the drain as well. Can’t recall turning it on purposely.

Do you live in close proximity to other people? It's possible that someone who lives within BT range of you has an Apple TV. Where I work, there are a couple that are used in conference rooms. If I'm close to those room, my phone picks them up. As your phone is simply recognizing what devices are within BT range, it's not a battery drain.

Dear Apple, please do something about your OS. Don't tell me that it's an issue of the battery. I've already had the phone serviced once for the battery so telling me that it's time for me to do something about my battery is, to put it mildly, nonsense.

Battery power should not drop from 100% to 0% in 4 hrs and when I plug it in, a miracle happens, my phone suddenly has 10%. Within 20 min the phone shows 60%. Trust us when we, the users, tell you that IT'S NOT THE BATTERY THAT IS THE PROBLEM. It's your OS. Because I am pretty sure your OS update doesn't suddenly allow us to supercharge the battery by 50% in 20 minutes.

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

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.

Update, after trying a full reset, reset network settings and swiping up to close programs constantly, my phone is steadily deteriorating, it now has a battery health of 63%. (86% just before the update)Has to be a software issue as it is the software that decides when to charge the phone and for how long. I have had days where it will not charge at all to others it charges in an hour, other times the battery percentage remains the same for extended periods to today I have it plugged in and it will not pass 69% charge level, it actually is losing charge while charging!!! I cannot get a run out of my phone now as it dies while I am out so cannot log my distance or even have music to listen to, that's with charging my phone fully before a one hour run. Apple have 2 year warranty but not for consumables like batteries, I have never felt so frustrated and helpless in my life. No matter what I decide to do its going to cost me money thanks to Apple's greed, not happy just to sell phones when they die naturally they go ahead and kill them prematurely. Irony is we go back for more :-(

I bought the iPhone 4s when it came out. The last update I did on it was the 8.3. (Because Apple messed up with Operating releases after the release of the iOS 7.

the only reason I upgraded to a newer phone was because... well, 6yrs.

my current phone. The iPhone 6s had no problems under the 10.2.1 system. LITERALLY! RIGHT after downloading the 12.3.1 I've had battery drainage issues. Which are ridiculous, and unacceptable

I’m totally with you Chris. I had called the phone support and they ran another restore factory setting and the battery is still running super fast even it’s off! I’m still waiting for them to sort out. My 6s’ battery just got replaced in Dec 2018. I really doubt it’s fhe battery issue... my other 6s is still 12.2 and still running fine with the new battery that’s replaced in Dec 2018 as well....

this is so annoying!!!

That is not helpful because that would be a work around.

My iPhone 7 Plus (company phone, company managed), since I went to 12.3.1 I have suddenly battery draining issues.

I hardly make phone calls, I never have WiFi on for long periods of time, mostly only 4G, I have already disabled it from downloading email in the background (I get a lot), have disabled a plethora of other stuff that was recommended, never used Bluetooth, running phone in Dark mode, disabled Siri completely, yet, Siri still comes up on top as the main source of battery usage and does not last me 24 hours.

If there were a braille option I would have tried that to to prevent the screen from using the battery.

All kidding aside, this aint fun. I am unable to upgrade any higher than my current 12.3.1 as it's company managed, but reading this post, that is not going to help me.

Apple, please enlighten us.

Apple is not going to reply to you here.

I've been using an iPhone 7 + for over two years now. I have had not problems with excessive battery drain with any version of iOS 12. Have you tried any of the troubleshooting steps mentioned in this thread?

iPhone SE and iPad 5th generation BOTH have ridiculously fast battery drain since installing 12.3.1. Drove to nearest Apple store 1 hour away a few days ago, and the “genius” told me there is nothing wrong with this iOS version, that my battery is just old (phone battery was rated as 85%). He reset network settings on the phone and said that would solve it. Put a new battery in the phone, charged to 100% and battery was at 4% after being out of the house last night for 4 1/2 hours, even though for part of that time the phone was turned completely off for a show. iPad hasn’t changed, doesn’t last a day now, when it went 2-3 days of typical use before this update.

I have been a 100% Apple devotee for >10 years (home and work macs, iPads, phones) and have promoted them to friends and family, even helped them purchase devices; I have been fond of the cross-platform fluidity of their “ecosystem”, but now you can do all that with Google. I am seriously considering jumping to Android for my next phone if they’re gonna keep releasing new iOS versions before fully testing them, then covering up their ineptness, meanwhile jacking up prices on new gadgets and denigrating older ones after shorter and shorter times. My loyalty is wearing very thin.

My iPhone 10 won’t even last half a day on a charge I used to go a day and a half before this patch is awful. I can’t load websites either screen freezes also I had to reboot my phone 2 times this week. Just now!!! My phone pop’s up battery low!!

iPhone 6S, update 12.3.1 --not just battery draining, but battery will not charge from a lightening cable.

Any fixes??
