The data line interface IC is not working properly, and the data line is damaged, so the data line needs to be replaced. The data line interface IC works normally, but a pair of codes between IC and mobile phone can't work normally. Maybe the golden finger of the interface has been used for a long time and is dirty. Clean it up and try again. The gold finger of the data line interface is welded to the circuit board abnormally.
Under strong light, check whether there is dust hidden in the charging port, pick it out with a toothpick, blow it clean a few times, turn off all the background of the mobile phone, try plugging in the adapter again after restarting, and plug it in several times. If it is invalid, it means that the inside has been damaged. Take the shopping receipt to the local Apple for sale and replace the adapter for free.
