So I'm at ten percent around 1:30, now I'm at 14 percent @4:30!!! What gives!?

You must have rebooted your phone and the battery gauge got thrown off. Check your battery graph. If you see a huge drop off, which would have coincided with a reboot, then that's your answer. In this situation, the battery level can sometimes climb as it settles back towards its actual level.

This is an oddity with all the SGSII variants that has to do with the rather unique Maxim fuel gauge chip that is included.
