I have this problem too. It works just for five seconds after I press the pins then it fails again.

Clean the iPhone charging port with a clean dry toothbrush. See if better. If not, you could try a Restore of iPhone with iTunes on computer. See if better. If not and there is Warranty or AppleCare make Genius reservation and take to Apple for resolution. If no Warranty, clean iPhone charging port again with toothbrush and small amount of Isopropyll Alcohol.
