I recently left my iPhone on the charger overnight on one of those chargers that can charge the battery twice as fast. I think i may have just fried the battery, but the apple logo will pop up for about 3-5 seconds and then the screen will glow a very subtle blue and then shut off again after about 3-5 seconds. DFU mode doesnt work and i cant connect to iTunes, are there any other home solutions i can try?

The fact that the phone is not recognized by iTunes leads me to believe that the Tristar IC is damaged. It is responsible for communicating with peripherals and coordinating the charge. This IC can be damaged by poor quality chargers.
I would check the battery first with a known-good battery, as that is the easiest thing to do. However, if that doesn't solve your problem, you will have to take your phone to a repair shop that does micro-soldering repairs to check the Tristar circuit.
