iOS 14.2/14.3 battery drain bug!

it ***** really yesterday when 7pm my battery on my 11 pro was only 20% left only wifi home and juste some data outside 20mn in 3g crazy normally like that i have 40 left maybe 50 when this time

so today here we go again with eco mode i have no choice till new update comes

I did a clean install through iTunes on the advice of the Apple CSR I spoke to just over a week ago; it made no difference. I also tried your suggestion of erasing and clean-installing as a "new" phone with third-party apps – that made no difference either. The apps are not (and never were) the problem: the phone continues to lose power overnight sitting idle on my desk, no apps open and no information given as to what is using up 25% or more of the battery overnight.

I guess I could use it as a paperweight from now on.

Even my two years old android phone is performing much better than ios 14.3.

I don't even need to low power mode and other bhlah bhah.

It has just been 7 days that I have bought my iPhone and not being able to use it peacefully.

It is a shame for Apple.

I installed new battery yesterday and It still drains battery overnight without any usage see screenshot.

I have talked apple support person and he said your battery needs to be charged. Than I changed it but nothing improved it still drains overnight without any internet and home and Lock Screen uses much of battery

I downloaded the 14.3 update 3 days ago, before that I could get through 80% of my day many phone calls, texts, emails and app usage (including a run with music and gps) before my battery got to 20%, after the update... I charge my phone all night have 100% battery when I wake up and 11am with minimal use a couple of emails and a phone call I’m at 20%

Thank you for all the suggestion here but it would seems nothing can be done at this moment from the community and its unfortunate that company like Apple does not acknowledge this.

I'm having the same issue with my iphone 12 mini to the point where I have to recharge it two times during the day, just being on standby, all apps closed and without 5G.

Consuming twice/triple the electricity to keep your iphone from dying does not contribute well to global carbon footprint and what was gained with excluding the charger is diminished.

I have the iP11Pro Max 512Gb (over 1 yr old) and iP12 Pro Max 512Gb (3 days old), both running 14.2 (weary of 14.3 battery drain issue). Both phones running same software, same layouts, same programs. What's strange is that the iP11 outlasted the iP12 by 15% in battery life. I ran the battery health (iP11 max hold 88% while Apple recommends batt exchange and iP12 max hold 100%) and both are showing the same battery usage. One particular app (State of Survival: Zombies) takes 40% of the battery on both phones as I play multiple accounts simultaneously and the iP12 still runs out of battery faster. Today, I tried not using either phone due to work and the iP11 still has 74% battery while iP12 has 62%. Not sure where the issue is here and now hesitant to download 14.3.

Tonight I changed network setting. I use 5G auto instead of 4G, I set it at 4G because I don’t have a 5G contract and I thought it was the best setting for me. Tonight I only had 4% drain with everything on and it was almost 10 hour standby. I will keep trying this settings some days now.

This is truly ridiculous.

My phone battery is abysmal now and doesn't last 24hrs after the auto update to 14.3.

Previously on 14.1 I had over 3 days!!! battery time and now my Iphone 8 cannot even last a day. This is horendous.

If I use Waze it doesn't even hold 1hr roadtrip, how dangerous is that Apple?

In addition my battery health is dropping 1% per week compared to 1% per 3 months before the auto update to 14.3 abomination.

I wish there was a rollback option.

APPLE: You need to fix this asap, I cannot believe a company like Apple takes the head in the sand approach and not even acknowledge this major problem.

Frustrated beyond words!!

That's quite a write up, enjoy your android. The reason I moved away from android was I got tired of waiting six months for my provider (Verizon & ATT) to push out the updated OS. Sometimes Google would have released a newer version before the cell provider had even tested and then pushed out the older version. Only the new android flagship phones came with the latest android update; everyone else waits from a month to six months and many never get the update.

I’m scared to look at my battery quality these days. Last I looked, it had dropped 3% in a matter of weeks.

An article I read said 14.4 added minimal battery life. For my iPhone SE 2020, I gained “a few minutes” of battery life. Very disappointing!

I did fill out a feedback form. I appreciate you spreading the word.

Well, I gave it a chance... waste of time. my iPhone SE still loses up to 20% sitting idle overnight with no apps open. And yes, I've done all the usual when it comes to preserving battery power. It dropped from 90% to 59% just sending my mom a text yesterday.

I've used iPhones since they first came out, but won't be getting another one. I've already purchased a different phone – Android, Moto G Power on sale for $170 at Target over the New Year... since I'm not a very heavy phone user, the battery lasts me up to a week before I feel the urge to recharge and even then it's still got about 40% left.

Yep, it's exactly the same with my iPhone Se. Shame on you, Apple, for not fixing this issue. I'm also thinking of switching to another brand because of this problem and the inability/reluctance of Apple to fix that bug..

But please don't start an Apple/Android in this thread, it just doesn't help.. :'( Other phones have other shortcomings.

Same thing here. I bought an iPhone SE 2nd generation during Spring 2020 and since I installed iOS 14.2 my battery has been drained super fast, even when I'm not using my iPhone. iOS 14.4 doesn't seem to be fixing anything.

I tried to avoid using my phone to keep it for necessary tasks. I'm hoping for a software issue soon!

Hi user0197,

No, it's the second generation iPhone SE. The battery is not bad at all, and it was confirmed by Apple Support. It's definitely a software issue has my usage is very minimal.

Thanks for sharing the steps. I really appreciate. However all those things and many more were done and nothing seem to solve the issue. The only way I can use my iPhone now is by activating the «Low power mode» each morning when I wake up. And even then, I think my iPhone went from 50% to 40% last night in an hour for just being next to me.

Thanks again for the help, it's much appreciated.

Have a great day!
