Cause 1: The IC of the Lightning interface of the data cable does not work properly, and the data cable is damaged. Replace the data cable. Reason 2: The Lightning interface IC of the data cable works normally, but a code pair between the IC and the phone does not work normally. Maybe the gold finger of the Lightning interface has been used for a long time, and there is dirt. I try to clean it up. Reason 3: There is a problem of virtual welding between the Lightning interface of the data cable and PCBA(circuit board) under the gold finger, and the data cable is damaged. Replace the data cable. Reason four: The probability of this problem is very high, generally upgrading a new system may lead to such a prompt, please replace the genuine original data line.
This situation is basically caused by the incompatibility of the charging line, which is basically a hardware problem that you can replace with a professional
