Please Help ... !!! My HTC One shows Grey Battery with "!" Icon ... ???

Working much better now ... No Charging Issues ... But a few times the same error occurs ... I noticed that the error occurs when the Battery V (voltage) is near 4.8 and charges properly when V is near 3.7 ... But most of the times no error ...

Have you considered taking it in for repair? They can at least give you a better answer for your problem I'm sure. Unless you are not near anywhere that can repair it.
