iPhone XS Max lightning port charging issue

When I contacted Apple-support, they said it was not an iOS issue but a sw issue that occurred when I set up an iPhone from an existing iPhone or a backup. Therefore there is no need for a bug fix of the iOS. Also they said it was not isolated to the new iPhone XS Max phones. The charging issue should therefore be fixed when I did a factory reset.

So, I used to have the issue, until I went to the FaceID & Passcode part of the settings. When I went to the menu and scrolled down, there was an option, called "USB Accessories" that was turned off. It basically makes it so that if the iPhone is idle for more than an hour, the phone won't recognize any external usb connections as a security feature. When I turned the option on, everything worked fine. It seems that there might be a flaw in the OS where if the feature is turned off, the phone won't recognize a cable that's trying to just charge the phone.

Tl;DR- Go to FaceID & Passcode in settings, turn on USB Accessories. It should work fine after that.

I too have experienced the Issue that users have been experiencing when charging their new iPhone XS/XS Max without waking it up from a deep sleep. Before, It would not begin charging without waking up the display once the cord was plugged in. What you need to do is go to Settings, Face ID & Passcode and scroll down to the bottom to the “Allow Access While Locked” menu and toggle on USB accessories. Once toggled on, your phone will charge regardless of being awake or locked in sleep mode. It worked for me and hope this helps all of you! No phone swap required!

Hello guys, so I’m pretty sure I’ve figured out what the issue is. I’ve literally swapped out 3 iPhone XS MAX at the apple store and I’ve spoken with them personally there about what the issue could be. So on the last phone I swapped out we tried to charge the phone before we even set anything up and the issue still persisted with it not recognizing the charger when the screen was off. We even tried the apple associates personal phone since he has the same one and guess what? The same thing happened to his. One of my siblings has the same phone also but silver instead of the gold and the same thing is happening to his. So after checking 5 iPhones and all those having the same issue we concluded that the issue is a software related problem that will probably be resolved in an update in the upcoming weeks. So to save you guys the trouble of waiting at the apple store don’t even bother switching the phone as I guarantee you will probably be having the same issue with the new one, so for now I would just be patient and wait for an update to resolve the issue. Thanks!

I never noticed this issue, but when i tested it with the official charger that came with the box i experience exactly the same charging errors.

When i test it with my normal 2.1 amp charger (anker 5 ports) and then i have no errors.

I think it's an amp threshold where 1 amp just isn't enough to get it charging properly.

Temporary solution, use a aftermarket 2.1 amp charger.

Apple should have included an 2.1 amp charger at least.

hey xMASTIFFSx,

unlock your iPhone, plug the cable in, it will charge now.

this is related to the feature that stops unauthorized access to your iPhone through Lightning Port,

there is a vulnerability in the iPhone Lightning Port that allows an attacker to gain access to the

information (through the Lightning Port) stored on your iPhone while your iPhone is locked.

this vulnerability is patched by disabling access to the Lightning Port after a given period of time when iPhone Locks,

so,

unlock your iPhone, plug it it, it will charge,

or

get a wireless charger

cheers!

Hello guys I saw one of the YouTube guys. And think this may help.

If you go to settings// Face ID and passcode// scroll all the way down and look for USB accessorie this option is off by default. Turn it on.

Basically this prevents to connect USB accessories from connecting when the phone is lock for mid than 1:00 hour.

Looks like it is something going on with that feature.

Note: That fixed the problem with the charging issues for me, but looks like this feature doesn’t work the way it is. Hopefully this issue will be fixed in the next software update.

Possible Hack to try until apple figures out the issue.

My iPhone XS max is experiencing the same charging issues. Most of the time it does not charge regardless what I do while it is powered on. I am beginning to believe this bug is a software issue and not a hardware issue (hopefully) by I have found a workaround that seems to get it to charge every time. When I need to charge my phone I first turn the device off then plug it in. One the lightning cable is plugged in I allow the phone to turn on on its own and after it will continue to charge until I choose to unplug it (regardless of how long I leave the phone unused/locked).

It looks like the last update did not address the issue for all devices. I upgraded to iOS 12.0.1 as I like to wait till the first patch prior to updating devices. On my iPad Air 2, the issues occurred. Note I am using a 3rd party *certified lightning cable. The workaround that worked for me is to actually unlock the device and the charge will start. I suspect it's some security issue for passive USB hacking. It will probably take a couple more patch updates to get all the various combinations sorted out.

Spoke with a Supervisor at Applecare and they advise me at this time it’s a issue that they are aware of and At this time they advise me to get the phone replac

It’s a new software update in iOS 12. Go to settings, Face ID and passwords, then toggle usb Accessories to Off. Done

Settings/Face ID/allow access when locked (turn on USB devices, it’s off by default). Problem solved

I think I figured it out!! I switched from the small white block charger that came with the phone and tried the iPad charger and it started working right away. We don't usually use those small ones in our house anyway so I am hoping this is a fix!

I had the same issue but tried this and it seems to be working fine now.

"Open

Settings app and browse for Face ID & Passcode. Provide your Passcode. Next scroll for the “Allow Access When Locked Section” make sure that the USB Accessories feature is enabled, to allow access to the USB port when the iPhone is locked."

Lemme know if this was helpful. I will update if anything changes

I think is a bug on IOS12 related to the new feature in the "FaceID & Passcode" section. "USB Accessories" . Unlock iPhone to allow USB accessories to connect when it has been more than am hour since your iPhone was locked.

Try enabling and then disabling that option. They should issue an update for IOS12 soon, there are some bugs that need repair specially this one.
