Hey, I have a charging problem with my Galaxy Note 10 plus. It suddenly stopped charging via cable. Also no data transfers via cable. So naturally I immediately cleaned the USB-C port. As this did not help, I replaced the daughter/ charging port board. Still nothing. To be clear, if I stick a cable in the charging port the phone does nothing whatsoever. Luckily the phone can be charged wireless so that’s what I´m currently relying on. I´m not an electrical engineer so I´m kind of wondering what to try next.
I would start by getting a schematic or board view file to follow the circuit path from plugging in the adapter then need to test for short in the circuit. It be difficult to tell you exact problem without diagnosing it with an ammeter but from your analysis it is possible to have a bad charging ic where some of the solder contacts became loose on the charger side and partially still intact is why working on the wireless side
