2 questions:

Is application CPU usage on Android correlated and how highly to battery usage? In other words, are apps that suck a lot of CPU also draining the battery or not necessarily?
Is there a way to itemize and display the phone's power use by application, at any given point in time as well as within defined time buckets and maybe view charts and such? Sort of like a diagnostic monitor for power usage by application or system component?

Thanks
