iOS 14.2 Reportedly Causing Severe Battery Drain

I noticed the quicker battery drain in my iPhone 8 Plus, but I was getting faster recharges too. And it seems to be the same in 14.3 for me as well so I dunno if they fixed anything or not.

I just could not understand how it ended up at 40% while in bed with me while I was asleep not being used!
 
Have 14.2 on an iPhone X, 11 Pro Max and iPad Pro... No issues

Logical Conclusion: Therefore problem simply does not exist outside of the imagination of a very few complainers (/s).

Not entirely true, as hardware keeps being improved. It's not a software issue that your Mac Plus of 1984 can't run Big Sur.

As for the drain, I would suspect that it is a runaway process busying a core at 100%. A common "feature" on both MacOS and IOS, and the kind of bug that Apple really doesn't pay any attention to. They have given up about fixing bugs.

Sure, but if both software and hardware is based on same ARM family, these isn't anything stopping them from supporting devices for 10+ years. It's sad if Apple have given up fixing bugs, and might explain all the recent battery drain issues and bricked devices.
 
What really sucks is you pay through the nose for the iPhone which, of course, is not just a phone but a multi-purpose device that might be running apps 24/7. A short time later, the battery loses it's charging capabilities and what happens? You simply pop in an inexpensive replacement battery and...uh...no, you don't. Apple won't let its customers do this on their own. It requires getting Apple people to put in another battery and you again pay through the nose for that service. Then you go through this a few times only to have Apple declare your model iPhone obsolete and no more iOS upgrades can be made.
 
I noticed this battery drain issue since I updated to 14.2 I own an XS. I was planning on re installing a brand new copy of iOS 14.2 and do iCloud restore. But Now I see it’s a wide spread problem it’s best to wait an update that fixes this.

I use an old iPhone SE (1st gen). I changed the battery a year ago and it works just fine. Last more than a day if I don't use it often.
What I noticed is getting really hot when I try to run a specific game that has ads (Brutal Street 2). Since I use Adguard DNS, it blocks ads in games and since it goes to 0.0.0.0 devs might be upset.

A WhatsApp video call (LTE) can drain considerably the battery.

So I guess it depends on the software being used.

Well with any video call you will have 2 factors ( well 2 major and one minor) : 1:the screen ( wich probably draws sidnificant power) is on throughout the call 2:radios ( 4g/5g/ wifi) are capt more or kess moussy due to the real time constand data use, so they have no chance to go to low power. ( minor power drain): video encoder/decoder is kept in active state for both decodeing (remote partys video) and encoding (video from local cam for remote participants). And then we have WhattsApp itself, i’m not shore wether it does its video encode/decode in hw or sw wich can significantly affect power usage. Not to mention the encrypt and decrypt of all the data sent over the nerwork. It all adds up

Had this issue on my iPhone 12 Pro Max over Night until I started to use my phone on airplane mode when I am home. It used to drop over 15+ % on standby without any app running in the background. Therefore it seems to be modem related in my case

Exactly the same for me with the 12 Pro Max. I've exchanged my unit and no change.
Hopefully it's a simple software fix

$69 for battery replacement on older devices.

Rather refusing to replace batteries in my experience even if I wanted to pay they always say well your battery does not need to be changed.

Hold on are they refusing to provide a servivice that adds money to their botum line, this does not make sense, or are they justbadvising you that a bettery change probably will not deliver the results you exepect?

Funny story - I went to the Apple store last year to have my 8+ battery replaced (was planning to hold on to it for another year). The replacement attempt failed, they ended up replacing my 8+ entirely, which qualified me for a free year of TV+.

That said, battery life on my 8+ has definitely been (a little) better compared to iOS 13, though I typically still need to charge it once during the day.
 
Definitely having this issue with my iPhone 11. Battery running down SUPER quickly even when doing very little and taking a very long time to charge - even when plugged into a fast charger - a matter of hours.

And my iPad Air 2 is even worse.
 
I had shocking battery life on my 12 pro. I did do a full erase and restore and it looks to be much improved.
I have a feeling it might be connected with the time it's seeking a cellular signal and if the area is variable it's seeking and seeking and burning the battery but not as severely as some others have reported here.
 
I'm surprised it took this long for somebody to post a thread on this. I seldom get through a day since iOS 14. I just figured it's part of the year-end saga of one of the worst years in memory. Please don't shoot the messenger, but I considered picking up ordered a Pixel-5 as an interim solution until Apple gets their act together.

NO, I didn't want to. I ordered one a while back, and it sat on my kitchen counter for a few days unopened. I got cold feet and figured I was overreacting. I guess I expected a patch to solve the issues by now. So, I re-ordered the damn thing' again this morning. Yes, I still have cold feet about it, but I'm tired of the reliability quirks. I have significant medical issues, and I can't afford to be patient indefinitely. Heck, the problems extend to my AirPods Pro. When I'm talking to the Mayo Clinic, they keep telling me they can't hear me very well, so I have to stop using them as well.

Please know I'm still at Apple fanboy through n' through, but there comes the point; blah blah blah. 🎻

Well a smart-shopping consumer would ask Apple if the battery is customer-removable before making the purchase. They will say it's not. Then that smart-shopping consumer can buy a different brand of phone that satisfies their overall needs.
But in your case you already know that the iPhone doesn't have a customer-removable battery so it makes no sense to complain about the high price you paid for an iPhone when you know you can't remove the battery yourself. You didn't have to buy an iPhone. Simple as that.

So what you're stating is the Pixel is perfect and without it's own set of issues right? Because that's exactly what you suggested based on your post. Maybe Google needs to get their act together too on issues the Pixel may have, because I hope you realize that it can't possibly be perfect?
 
12 Pro Max here. 0 problems. Actually had trouble trying to drain the battery. Ran all kinds of stress tests but it's really difficult to run the battery down. Wanted to test some chargers at low SOC.
 
I have an XS with 14.2. I had one day where my battery was exhausted by 1:00PM(November 30th) and I just thought some app was left open and working. I normally use 50% of my battery each day before I recharge at bedtime.
 
My 2018 iPad Pro read 100% after leaving it charged like I normally do overnight. In less than 5 mins, I got the low battery warning and saw that my battery dropped to 1%. I let it charge for about 8 hours and it still sat at 1%. So I restarted it and plugged it in again, the battery started to charge and was at 100% in a few minutes.
