Jelly Bean :: Note 2 Slow Charge Very Fast Drain?

I have had my Note 2 since last spring, I noticed in September that when using my original charge cord (plugged to wall) it would only charge when held in certain angles and very slow, I couldn't use while charging as it would drain it. I tried using my boyfriends nexus charger and that seemed to work. It was still slow but at least I didn't have to be constantly moved to certain angles (still discharged if used while on charger though).

If I plug my phone in at night (let's say at 14% battery life) by morning, over 8 hrs later, it's only at 60 % and then drains completely in 4-5 hours, while I'm at work and not even using it, if I'm using it it goes down 2% a minute.

This is getting so frustrating, I have no clue what's wrong. I've done a factory reset and nothing changed. If I use a universal docking station my phone actually charges very quick, at a normal speed. I'm not sure if it's the battery, usb port, or charger!
