What would cause this battery drain?

Im at 60% batter since about 6 hours ago.

Display 35% Would be more understandable if it weren't on the lowest setting all day.
Cell Standbye 16% WTF is this?
The Weather Channel 13% I have not checked the weather once, sometimes this absolutely KILLS my battery
Phone Idle 9% Why?
Maps 8% Have not checked maps at all since I used GPS this morning, and was 100% charged since
Android System 5% I would think this should be the highest

If I had just killed all tasks earlier would this have solved the problem?
