I called Sprint and asked them if there was something else I can do to improve battery life on EVO. I told them I did all the dimming screens, turning different radios off( wifi, Bluetooth,4g,) all that stuff & the advanced tech support guy said their's nothing else he knows off. Then he said he can offer me a $50 credit on my bill to buy a battery. They don't give you money but the fact that they're giving you $50 off your bill to "buy a new battery" is a step in the right direction.( its not a bad way to get $50 off your bill either if your short that month let me know how this works for you guys
