iPhone doesn't charge by cable, it charges only wirelessly.

Hello,

recently I bought i secondhand iPhone 12, but I was scammed.

The iPhone doesn't charge with the lighting cable. It charges only with the wirelessly charger. Actually, when the phone is off and I'm trying to charge it by cable, it is showing that is charging, but it doesn't. (Battery level doesn't go up.)When the phone is on and I'm trying to charge it, then nothing happens, no charging indication at all. The wirelessly charger is working.

Firstly after I bought the phone, the battery died at some point, because it went to zero, so I try to charge it, but the battery was completely dead. I went into an apple store and they told me that it was probably water damage, but the guy wasn't really sure, because he couldn't see clearly the water indicator. He mentioned that he couldn't see any corrosion to the port and that the port seems to be clear. They didn't try to charge it wirelessly. They connected a diagnostic tool and they said to me that they were receiving some signals, but they were too slow, so probably I have a bad motherboard. After this, I bought a wirelessly charger, and the phone charged and start successfully! It is working ok,(except for the ear speaker, which is too low, barely you can hear it). If a try to connect it to my mac, then sometimes I'm receiving a USB indication to the iPhone for some seconds and then nothing. Do you think if I replace the charging port board, it will fix the issue? I'm planning to "bath" the board in 99.9 alcohol, too.

I can not contact the guy who sold me the phone, nor Apple is giving me his details.

Hi Demetres,

Yeah, I'm with you; it seems like it would be worthwhile to try changing out the charging board. Since it is charging wirelessly, that tells you that the internal charging circuitry is working, at least as far as the wireless circuit is concerned. While not definitive, it is a good sign that charging works on the motherboard.

Replacing the charging board is really the only repair possible in this case; if there's anything else wrong with it, it's on the motherboard and that repair is far beyond what us home do-it-yourselfers can accomplish; in fact, it requires specialized microsoldering expertise and equipment to fix.

It seems like an issue of less importance to you, but the earpiece speaker is replaceable. If you buy the full assembly, you'll lose Face ID, but if you can solder and unsolder just two small points, the speaker itself can be replaced without losing Face ID. I wrote a guide for that for the iPhone X, but the steps are virtually identical for the 12. I can give you more details on that if you like.

Hello,

Thank you for your answer.

I have to add that I think that the phone is overall a little hot while using. Not overheating, but hot. It is like this, only when I use it if the phone screen is locked and off then it doesn't get hot. Yesterday before I slept I left with more than 25% battery and the next morning battery was dead.

I am suspecting a ground issue. Or if I am lucky the charge circuit is fried and somehow is emptying the battery by a shortcut. As for the ear speaker, I saw, that if you only desolder the old tiny speaker and solder a new speaker from the face id part, you are not losing the face id functionality.

I open the screen of the phone and the water indicator doesn't seem to be enabled. I noticed that on the edges of the screen in the glue part, there is a lot of dirt. (This rings the bell that the phone was wet, but I really don't know why the indicator didn't change color).

Did changing the charging board work?

Why do I not see any guides to replacing the Lightning connector? My i12 charged fine for the first year on that connector as well as played music through my good headphones, and then the entire port died. Which also means there is no wired headphone option -- just another "design upgrade" that I really resent Apple for. Any guides coming?

@markdowdin11100 With the huge number of devices iFixit supports, I strongly suspect their department that writes guides prioritizes the most sought-after ones and lets the rest go. I personally wrote a significant number of the iPhone X guides since I was working on them regularly and the guides I needed weren't there.

So unless a user steps up, I wouldn't hold my breath on getting an iFixit guide for the charging port.

That being said, iFixit is not the only site making phone repair guides. There's a Spanish site called Nadie Me Llama Gallina that has just the guide you need; of course it's in Spanish, but used with the Chrome browser's translation, it's more than usable.

Of course, since you're doing the repair anyway, why not go ahead and take lots of pictures as you work and create your own guide to that repair?
