This is my first Android phone in a few years but the last one I had would charge with it plugged into the computer via the USB cable, but either something is wrong with my phone or the G4 does not charge that way. I did notice that the phone would get warm to touch while plugged into the computer, but I left it on the computer all night last night and the phone was almost dead this morning. I tried it on another computer when I go to work and it would not charge there either. Is this a problem with my phone or a problem with the G4. Thanks for reading.
