iOS 14.2/14.3 battery drain bug!

for me they lie most of user have problem update ***** since 14.2, 14.1 was fine.

yes lot of APPLE genius are here ..... to tell us eh just reset and all is fine so funny to read that... XD

crazy..... i m not novice with iphone ..... hope APPLE is aware about this BIG PROBLEM

it s normal update is necessary no need to reset phone or other things useless ... just wait new update hope they will fix that soon .... my 11 pro is 60% left when normally 80% maybe 85% i did nothing just send few sms 1 phone call 8mn some internet outside like 10mn and whatsapp 20mn crazy 14/2 14/3

After a couple of days of my phone giving me a solid two days charge after resetting & then restoring today my phone went back to not taking charge & needing to be plugged in constantly. I was on the phone to Apple support for well over a hour, and they have sent out a box to pick up the phone as they believe it is a processor issue.

Personally I think this is nonsense as the battery drain only started after the osx 14.3 update, but whatever, if the issue gets sorted I dont care.

Pretty annoying that a £1000 phone can be rendered useless by a software update though. After issues with my Macbook updating I will be turning off auto updated on my devices from now,

We all know it's 100% software bug and only solution is Apple to release a patch. It may be 14.4 or something.

We can cooperate each other to narrow down the issue so that we can get the patch from Apple sooner. Instead of insulting other people's intelligence, do something positive.

I'm a macOS/iOS/iPadOS app developer and probably know more than average iPhone users.

Hello, I can say my situation too,

I have Iphone 7 (old but still fine), before I had 63% battery health and ios 14.1, now I have brand new battery - 100%, and ios 14.3.

Now after update it´s worse or comparable with the old bad battery...

2 hours of using on low brightness, just social sites and safari, no videos, it almost drain all battery... nonsense

Just wanted to provide a brief update. As I wrote yesterday, I ended up replacing the battery (1st gen SE 2016). Today, nearly 12 hours after it was disconnected from the charger the battery is at 59% after a number of phone calls, messages, emails and Safari use.

I do believe that the 14.3 update has caused the battery drain rate to increase exponentially; before the update it would drain from 100% down to +/- 30% in the same amount of time.

Cheers.

Replying again with an update: I can now only turn my phone on when it's plugged in. When plugged in it shows as fully charged – if I unplug it the screen goes black and when I try to start it up, battery shows as uncharged/red. Plug it in and all is fine again.

My iPhone 8 now does EXACTLY what you described Moonspinner. It's not really a "mobile phone" any longer as it needs plugged in to the mains all the time 😡 At least I'm not going outside at the moment thanks to the pandemic...

I am experimenting with Low Power Mode after reading stevepo's post 🤞

Mine lasted about an hour and half on Low Power Mode but just now decided to shut down and started the recovery process (for the 72nd time). A total disaster 😡

I bet Apple will say "service the battery" - that's what they said to me when they did the diagnostics on my phone a few days ago.

not true if you charge during night your iphone will be 100% when wake up !!!! cos on the plug lol you FUNNY !!!

ok i tried something just restart iphone actually seems better i have to see other days, but IOS update is necessary i m sure.... it s 1:29pm i have 77% i used my iphone since 8:30am will see if ok till 23pm like 30% left is ok.

I have background refresh off for everything: I started doing that after 13.7, which is when I first started having battery drain problems. It's just awful with 14.3... though toggling Airplane mode on and off seems to have stopped the problem where my phone was dying the second I unplugged it, last night it drained from 100% to 11% while sitting on my nightstand. Nothing was running in that time, but the battery monitor shows activity in apps I don't even use and never have. Like the Mail app... I don't use the phone for email and in fact have never ever opened the mail app on the phone. Yet there was activity in the app overnight while I was asleep. What even?

I'm so furious at Apple. They want to charge me to replace the battery but the battery health is at 93% and the person who ran diagnostics for me yesterday says there is nothing wrong with the battery or the phone.

Hi

I’ve noticed faster battery drainage after swapping the iOS 14.1 to iOS 14.3.

I can tell I use standard iOS application in most of the time. No google chrome.

Apple,pls, fix this bug.

I’ve been happy with the original battery life till now.

the battery life percentage running out in front of my eyes. Meanwhile I read a few replies and writing this the battery dropped down about 2%

I have similar issues since having upraded my iPhone7 to iOS 14.3! The phone has a healthy battery however the battery tends to go from 100% to less than 20% within a timeframe of roughly 7 hours, while the phone is in standby, doing more or less nothing. After rebooting the phone it may be OK for a day or two, but then again this phenomenon occurs. When looking at the battery usage indicator, I notice an unusually high amount of usage by the home and lock screen as well as the AppStore service. I also noted that charging the device takes a lot longer than it usually does. Pretty sure that this is a software bug and not related to any hardware issues.

at a first glance it'd be so, but for example, I had 14.2 on my iPhone 11 wirh two days of battery life. The second after I upgraded to 14.3 the battery went from two days to maybe 8 hours at most with minimum or no use.

I saw the same linear discharge on multiple devices, sure it’s IOS and not the third party app because my iPhone 8 Plus was doing this right away after upgrading to iOS 14. I’ll post battery stats after this night.
