Samsung Galaxy S2-Phone says battery is charging when it's NOT plugged in.

I got a rude shock when I saw the battery was shown charging when the charger was unplugged. I had the phone on  a car charger when on a long drive before this issue set it.  And the worst thing to happen was upon shutting down the Samsung Galaxy S2, it didn't boot and had the battery charging logo flashing...and it was never plugged to a charger.
Solution:

1. The issue is with the USB port. 
2. The center part of the USB port was touching the other sides of the port which made the device think the charger was connected but the fast was the port was getting short.
3. All you need to do is to use a needle or a safety pin to space the center portion (to be done with the battery removed and phone off)  else
4. Plug in the charger again and move the charger pin slightly up and down so that the charger pin would center the portion. 

Problem sorted. But also ensure that you clean the port of any debris.

Simple :)
