Thank god for this thread. This issue had plagued me for a week. Never any problem with the phone charging when it was connected, I had the issue of it thinking it was charging when it wasn't even connected. As this wakes the screen it was killing my battery. At first I thought it was a rom I just flashed so I went back to a previous one but that didn't solve it. I used my air compressor and blew out the usb port for 3-4 minutes at 120psi. No improvement. In a desperate attempt to keep my phone from draining I cut the plug off one of my car chargers and would stick it in the phone when it was in my pocket. This prevented the phone from waking up in charge mode but it only lasted a few days. I emailed wirefly Friday night to see if the phone was covered by factory warranty and haven't gotten a reply yet. Then I came across this thread. I did exactly what someone suggested and cut a q-tip down to make it thinner, soaked it in alcohol and wiped out the inside of the port. It was fixed! Then I plugged it into the charger in my room and the problem came back when I unplugged it! I cleaned it again. All better now for the 2-3 hours since I did it. I have since plugged it into a different charger and had no problems since unplugging it. I'm ing stoked!
