Whenever I use the Razr and use it normally while on the charger, it doesn't charge. Every single phone I have had in the past I could use it and watch it charge as I use it. It will only charge while it is in sleep mode. And when it charges, it doesn't go at 1 percent at a time; it goes in 10 percent intervals. I had it on the charger not in sleep mode for almost an hour and a half and it didn't gain one percent. Please help!!
