iOS 14: No longer charging

After upgrading to iOS 14 on my iPhone XS Max, everything seemed to be okay at first, but then tonight the phone decided it had had just about enough of that whole "charging" business. Tried it on multiple devices, across multiple different cables, including plugged into the wall. Tried hard reset. Tried it while the phone was powered off; in doing this, upon plugging in the cable, the phone powers on, so it clearly *recognizes* the cable plugged into it. No indication of even trying to charge, no chime, no green battery, nothing. As a result, it won't show up in iTunes, so I can't make a backup and restore the system to any previous state. Everything else seems to be functioning as it should.


All I can think is, since the unit clearly recognizes cables plugged into it and so the connector is probably functioning, that this is a software issue with iOS. Any thoughts on things to try?

Check my last post here:

https://discussions.apple.com/thread/251804766?answerId=253527075022#253527075022


I disassembled my iPhone (I am an engineer).


I checked the voltage level of my battery. It is 3.3 Volts. This voltage level means the battery is just empty. It was discharged to zero. But the iPhone is not able to charge it anymore. I tried a new original battery. And it works.


 


Summary


So, because of the charging problems after update of the iPhone to new iOS the battery was discharged to zero and the iphone was not able to charge it to an appropriate level.


  1. I want to check my old battery further if it is damaged or not.
  2. I want to check my new battery if it works properly to get this battery to zero and then charge it again to

the 100%.

I wish I could change at least the title of my post. At this point, the problem isn't charging; it charges just fine on a wireless charger. The problem I'm having is that the USB handling is just gone. It'd be nice if Apple had a series of tests I could do here that would confirm whether the problem is actually a problem with the Lightning port (which I don't believe, but might be) or with the OS. But then, that'd mean they'd have to admit they made a mistake with their latest OS release, which, they didn't want to admit that even in the beta testing phase, when a huge chunk of people were like, "My charging disappeared" or "My USB disappeared".


I mean seriously. At this point, if I could revert the phone to 13.7, I absolutely would. This is torturous.

You know what? You might have actually given me the final piece of the puzzle here.


We already know the iOS 14 upgrade causes an *immense* initial draw on the battery, something that was easily the number-one complaint about the upgrade itself. Between running update processes in the background and forcing updates in the foreground, the power draw was much larger than I believe any other iOS release.


It's entirely likely that the folks at Apple anticipated this, and decided to include code to reduce power draw by other, "less necessary" elements, including but not limited to the wireless charging, USB, and camera / flash LED, in order to make the transition to iOS 14 seem like less of a problem and more overall successful. ****, I might even say that it was their intent to have the code then restore that functionality once the initial power draw boost was over. However, it would appear that someone forgot to include that, because a large number of people are still without. They fixed the camera / LED item because for many, that destroyed half the functionality of the phone, but these other issues have been largely ignored because "you can work around that".


In radio, there's a well-known thing called the reciprocity theorem, that states that an antenna's receiving characteristics are equivalent to its transmitting characteristics. The wireless charging on the iPhone is an inductive charge, but that's still a form of antenna: If power is reduced to the receiving antenna, its ability to receive is subsequently also reduced. That would explain what you're seeing, that the induction charging only works if you remove the back plate.


Similarly, USB is a signal transmitted down a wire. If the phone's USB receiver has reduced power, its ability to see that signal is also summarily reduced. So, while the phone sees the signal well enough when it's off to power itself back on, it doesn't see the signal well enough to actually consider it a proper USB connection.


I think we're getting somewhere here. I sincerely hope Apple's engineers read this, but I know it's called the "Community Forums" for a reason. :V

Hi,


like I wrote, I have the same problem with my iPhone XS. Check my update here: https://discussions.apple.com/thread/251804766?answerId=253535644022#253535644022


I went to Apple Store. They told me they were not able to test and to analyze the problem due to the dead iPhone. But they told to me also that is a hardware issue and the Battery and IOS 14 have nothing to do with it. (:D I don't believe that).


So, after that, I replaced my battery with new one (also original one, from other iPhone). My iPhone worked prety good some time, but then it did the same thing again. It did restart and started with a bad battery and without charging possibility.


This time is the voltage level of this second battery is about 3,7 volts and 37% of charge. But the battery is recognized by the iPhone like 1%.

**UPDATE** I have had the same issue where my iPhone XS Max did not charge. I tried to update the iPhone through the iTunes app on PC, but my iPhone didn’t connect. When I tried a new charger that my friend just bought, it charged my phone. The problem could be the charger. Maybe the support of the charger on the newer version? TL;DR Get new charger and see if it works. You could get one for free if you recently bought your phone

So, in this case, your problem was your charger. But we don't have this problem. I have two Apple charger and one powerful charger with DP and 20W. Nothing works. The Lightning Port is clean and is 100% not defective.


Without a sim card in my iPhone I can turn it normal on. The battery is in a regular state (60% of charge) and I can charge it with any of my charger adapters.

Hi Baphijmm,


I've just installed iOS 14.0.1 this morning on my iPhone 7+, I charged my phone once until 50% and can't do it again. I'm now stuck with 29%.


And like you, if it's off and I put the charger on it's booting but no charge whatsoever.


At first I thought it was because the connector was dirty but I've cleaned it and it doesn't charge.


Never had an issue like this before...
