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.
