So this is weird. It has happened a handful of times but I have yet to determine how and why. Randomly, the battery drains rapidly as if I am using the radio for an extended period of time, but I am not. Today I was on the phone for probably 15 minutes total. I went out and used the iPod and played music, but it was paused when not in the car. My usage says 2 hours and 14 minutes since last full charge (last night). WTH is using what for 2 hours and 14 minutes? What falls into the 'usage' category?
