My Mi 5 used to be fast charging, but now it's slow to death, and there are fast charging signs on it. Looking for a solution?

It is recommended that you change a data cable, because I also encountered the problem of slow charging of millet 5, and asked the solution on the forum, but the methods of other people in the forum did not solve the charging problem, and then took a friend's letV data cable to rush it, and solved the problem of slow charging, so if you have a slow charging problem of Millet 5, you can directly change with the data cable
