Users complain iOS 14.2 causes some older iPhones to overheat, rapidly lose charge

(2020/12/07)


Apple released iOS 14.2 last month, with a laundry list of 24 security updates [1]some of which were being exploited in the wild , leading The Reg to [2]urge users to patch ASAP . Those sensible souls who heeded the call, however, were gifted with 100 new emoji, dark-mode wallpapers, and, according to users of certain older devices, rapid battery drain.

Affected devices, users have said, are losing as much as half of their charge in just 30 minutes. This, according to posts on [3]Reddit and the [4]Apple Developer forums , is accompanied with arduously long charge times and device overheating.

"My iPhone SE(2016) and iPhone 8 Plus were just fine until the 14.2 update. Now the fully charged battery drops to 45 per cent overnight and the charge drops rapidly even while simply reading my email. This cannot happen on both iPhones unless there is something wrong with the iOS 14.2 update," wrote StarFC on the Apple Developer forums.

"My phone battery was perfectly fine before update. Now it goes to 1 per cent from 70 per cent in matter of minutes. Some times it is even black out and I have to reboot my phone. After update, overnight [my] battery gets drained even [if] I have full charge," complained another user, bhandarip.

Per the reports, the issue appears to affect a smattering of previous-generation devices, including the iPhone 6s and 7, as well as the iPhone XS and 2018 iPad Pro. The fact that this behaviour coincided with a major operating system update suggests this is a software-related issue. And while it's theoretically possible to roll back to an earlier version, Apple [5]stopped signing iOS 14.1 last month , making downgrades almost impossible.

We've asked Apple for comment, and in the unlikely event it responds, we'll update this post.

Eleven! Eleven! Elevator: Could you please repeat that?

This isn't the only quality-control woe to confront Cupertino in recent days. Faced with complaints about [6]the fault-prone iPhone 11 display , which in some cases can become completely unresponsive, Apple has been forced to open a servicing program — much like it did [7]with its loathed Butterfly keyboard .

"Apple has determined that a small percentage of iPhone 11 displays may stop responding to touch due to an issue with the display module. Affected devices were manufactured between November 2019 and May 2020," the page said.

Those suffering with duff phones can send their devices back to Apple for a complimentary repair, with the caveat that those with cracked displays may have to pay extra.

"If your iPhone 11 has any damage which impairs the ability to complete the repair, such as a cracked screen, that issue will need to be resolved prior to the service. In some cases, there may be a cost associated with the additional repair," Apple's support page said. ®

Since Apple practically force their users to upgrade every year or two...is it to be expected that this sort of thing will happen on devices older than that?

Either Apple didn't test properly on the older devices....or they know but don't care since it'll force people to buy the new shiny if they want a working phone again.

What makes you think that?

Not noticed any battery issues.

Erm, with all due respect, that’s bollox imo.

I have the following on 14.2:

SE 2016

6s

6s Plus

No difference to 14.1

In fact iOS is improving all the time. I have very few, if any, problems with these phones compared to the decade of suffering under Android and Windows Phone. And my very reliable iPhones are half the price of the problematic Androids.

There, fixed it for you. You’re welcome.

It is possibly only some of the given devices. Apple may have varied components are the production life of the iPhone SE (2016), for example, and only some have this issue with iOS 14.2.

My iPhone 7+ has been doing this rapid battery draining malarkey on and off now for months, so it's definitely not something to do with the latest iOS14 update.

It's intermittent so hard to pin down. I've had it drop from 70%+ charge to 3% in a matter of 15 minutes or so (with the phone not being used) ... then managed to have it continue to function on that last 3% charge for two or more hours.

So it leads me to wonder if it's actually draining the battery, or if there's some glitch that's causing the phone to misreport the actual charge level instead?

And people wonder why I haven't upgraded since...

A Severe Strain on the Credulity
As a method of sending a missile to the higher, and even to the
highest parts of the earth's atmospheric envelope, Professor Goddard's rocket
is a practicable and therefore promising device. It is when one considers the
multiple-charge rocket as a traveler to the moon that one begins to doubt...
for after the rocket quits our air and really starts on its journey, its
flight would be neither accelerated nor maintained by the explosion of the
charges it then might have left. Professor Goddard, with his "chair" in
Clark College and countenancing of the Smithsonian Institution, does not
know the relation of action to re-action, and of the need to have something
better than a vacuum against which to react... Of course he only seems to
lack the knowledge ladled out daily in high schools.
