The tail plug of the phone is plugged in, how can it be charged? It is not broken, but it needs a long charging plug to be charged. Is the tail plug repaired or should it be replaced with a new one?

Change the data cable, the interface wear will lead to less charge. My fast charge sign is still on. It's slow to charge. Change the line perfect solution!

It could also be a problem with the charging port on the phone.

Normal use of the battery and charging plug can not be broken.
