I read and tried the suggestions, before I posted this, but I am at a loss. I have used the original EVO SHift 4G HTC AC charger with the the original USB cable, two other AC chargers and 3 different USB cable combinations, I have used my car charger and my laptop USB port to charge the phone. I have let it charge for 1 hour, two hours and overnight, multiple times. The phone never charges more than 27 percent the power indicator remains yellow! Any ideas?
