iOS 14.2/14.3 battery drain bug!

Good advice from FinalCutPro7473 to contact "Product Feedback". I wonder if Apple even reads these discussion threads. Good idea to register your complaint via their feedback page. I wish they would at least acknowledge this issue exists and if they are working on it. I've even completely wiped my phone and downgraded to 14.2 but soon realized I lost all my contacts and pictures and the 14.3 backup of files would not load. So I reverted back to 14.3 IOS. Still have the bug. Its a shame we have to resort to disabling so many features and run in battery saver mode just to get a few more hours of battery life. I'm a light user and previously I could get 2 or 3 days before charging. These days I have to charge 2 to 3 times a day. Like everyones else, Even with no usage at all while I sleep, I'll loose 25% overnight.

I have an issue regarding the iOS 14.3 update. I updated my iPhone 8 Plus yesterday. After I opened my phone this afternoon, the battery drained from 80+%to 22%. I checked the battery info and the MAIL is running on background, which I am not using the mail, and IDK why it is opened after I updated my phone to iOS 14.3.

I started having random rapid low battery indications with 14.2. Still have the problem with 14.3. Battery fully charged then phone suddenly goes dead and shuts down. On restart shows around 10% battery. Plug in to charge and almost immediately goes back to 90+% battery. Have to go through this two or three times to be able to use phone normally. Getting really tired of this “bug” not getting fixed. I’ve got an iPhone 7.

Apple you have a problem with 14.3 that I suspect you know about by now.

Please acknowledge it.

I have an Xs and a Mini4 that I am abled to visually watch the battery indictor fall from 100% to 5% in less than 90min.

I have erased and reset all settings and started without restoring from backup as well as a DFU recovery on both devices.

The problem persists on both devices despite this troubleshooting.

Both the iPhone and the iPad get smoking hot.

This is my ticket for the iPhone Xs 101295232794 from 1/12

This is my ticket for the iPad Mini4 101297258716 from 1/14

Spending hours on a call with your support teams it not fair to them or us when you know there is a problem.

Also how hard would it be to provide the users with an ability to choose an operating system version when you do a DFU recovery?

Since you decided we can't be trusted anymore to downgrade our iOS versions after iOS 14 you need to be a bit more proactive in fixing these issues....Beta 14.4.2 doesn't seem to solve the problem, I'm running on both the Xs and Mini4 and battery drain is horrific.

What hapoens IF you use airplane mode and turen wifi and Bluetooth on?

What are your settings in network? 5G/5G auto or 4G

When i choosed 5G auto my drain disapeard, i hand it on 4G beqause i dont have a 5G plan with my operator

After this change of setting my phone drain 3% at night and holds a lot better on daytime to.

> Also (also!) just noticed that my phone had been set to enable automatic updates, which is something I've always had disabled.

Same here - disabled it right now 😧 very fishy...

I can confirm that factory reset does not make any difference. I think apple has to fix the bug.

What does it say for battery health on your 7?

If it's the original battery still, you might want to consider replacing it (the battery).

99% of new.

not to sound like a broken record...

Going to battery usage, Messages, Photos (with background activity, even though I forbid it...), Phone (I was on a call for 15 minutes, which should use the LOW POWER cores as per apple marketing)...

Home and Lock Screen is now much higher than it used to be. I don’t use widgets, so please don’t ask.

And Mail - but I manually pull, and do not have any dynamic push (ie iCloud/me, exchange, gmail, etc).

Safari is far behind, and chrome is not on the list, since I don’t use it.

crazy problem is not my phone but those update 14/2/14/3 my iphone is like new !!!! when 14.1 and before all was fine !!!!!

we are all in this case, only help is APPLE UPDATE !!!! not to check the battery health or drain battery till 0% or reset iphone like new !!!! when most of our iphone when 11 pro or other not so old are 97% left !!!! like someone said there are many genius bar here ..... just hope APPLE works on this update cos it s not acceptable to have iphone like that and have to use my 11 pro with ENERGY ECO till drain bug is fixed, my battery is 70% now and normally i m 85/90% when at home and just do some check.

When are they going to fix it....

More likely after they fix the Youtube issue with Apple TV...

On a serious note: I've noticed a drastic battery drop after 14.3 upgrade. Good thing that I have a battery cover - that helps a bit.

Otherwise, it goes from 100% after disconnecting from the charger down to 28% in about 2 hours.

I've ordered a replacement battery, since the original battery is four years old (2016 SE) but Apple is getting worse and worse with its updates/upgrades. I am scared to upgrade my Mac to Big Sur after reading the horror stories of people reporting their good working machines getting bricked. And Apple tech. support blows. I spoke once with an idiot who was replying "LOL" when I was describing the issues I was dealing with. I think Apple needs to concentrate on quality control...

Sorry for the off-topic.

Cheers.

problem is not data on or off !!! i dont use data when home normally a sunday when 7pm i have 80% left now i have 60% with eco mode lol, an update please, no need to find what is the problem, all iphone have no problem except if your battery sucks old one but for those like me with 97% health one, problem is just 14.2/14.3, problem is IOS.

Good for you AzizBhimaniMax, but for many of us the battery drain extremely fast since iOS 14.2 and iOS 14.3 doesn't provide any fix yet. I have a brand new iPhone SE 2nd generation. I've ran some tests over the phone with Apple support and everything is in order on my phone, but the customer support agent did agree that my battery was draining way too fast for absolutely no reason!

So yes, there is an issue for some users.

I had problem in 14.2 but now with 14.3 its fine, Apple are powering up their devices yes its true but its still fine to use, even Samsung with all their powers have not reach 2 Trillion worth so think about it, their software is everything otherwise it would not be the company which it is now, use it, if you dont like then look for alternatives, I moved to S20 and guess what i came back to my Xs Max because of the software so smooth even without 120hz it feels better with smooth gestures and app handling, so understand it.

Dude, this is clearly a bug, I´m an iphone user since 3g, so I dont have a problem that would led me to go for another brand. I´m just trying to hepl other dudes since this is historically a common issue on ios updates, this is not new (at least for me) and notice that a big part of the people having problems, comes from devices like 6s, 8, x and xs, even my 11 so I think this is not apple powering up devices via os update, this is a bug.
