I would try what LordVincent mentioned and make sure that your charging port is clean. If that doesn't work, try doing a factory reset? You'll lose everything on the phone if it's not backup up with an app like Titanium but as long as you have a gmail account you'll be able to get your contacts back. I don't know if you're rooted or not but you can do a factory reset even if you don't have root.
From a powered off phone, press volume up and power at the same time until a black screen with blue writing comes up, then let go of the buttons. Using the volume buttons, scroll down to the wipe data/ factory reset option. Use the camera button to select and do a factory reset. Hopefully that will fix your phone.
