Phone Says It's Charging When It's Not Plugged In.

So I don't know how it happened, but after unplugging my phone from my computer, it thinks it's charging all the time, even when unplugged. I've tried everything to fix it, clearing battery stats with CWM, a complete nanroid restore, swapping batteries, you name it.

Does anyone have any suggestions of what could be causing it? Between the bugs and the pathetic battery life, I'm rapidly approaching my wits end with this phone.
