My New Trent charger has always been like carrying a DieHard battery in my pocket. Until recently, then it's been taking forever to charge the RAZR. So the other day I let it drain down completely then recharged it; now it's back to it's old self. Charged the RAZR up 40% in about 15 minutes. So FYI if you are a New Trent carrier ( I never go to the bar without mine) do a complete drain and recharge once in a while.
