What do you mean "marks" charging? You mean the charge icon appears on the status bar at the top and lockscreen? Have you tried other chargers? It might be an issue of a bad battery. Take the battery out and spin it on a flat surface, such as a table. If it spins like a top then its a bad battery and you should get a replacement. This could be the issue since the battery may not be holding the charge.what can i do nothing seems to work help please
