My phone charged fine till a few days ago anywhere I plugged it in. I charge it via wall charger and USB through my computer and in my car. All of a sudden the other day it stopped charging when I plug it into the wall. It will charge in the car and through my computer. I even plugged it into the USB port on the T.V. last night, just to see if it would charge and it did. The problem with this is that I have to leave the T.V. on all night or if I charge it with the computer I have to try and keep the computer from going to sleep or it stops charging. I am using the same USB cord via the computer I used in the wall. Although I have tried different cords and wall outlets. I have looked to see if there is a setting that will only allow it to charge via USB and I cannot find one. I saw somewhere online that this setting doesn't exist anymore with ICS. My phone is my lifeline I have to keep it charged any reliable help will be greatly appreciated.
