The Android OS monitors the power consumption of running apps and hardware (display). As you may guess, this is a useful feature as it allows to track down energy greedy apps.
Is there an application that would do such monitoring on Mac OS?
It should calculate the percentages of the charge that an application/process/hardware has used.
I use plenty of little software that runs in the background permanently. It would be nice to know if such little helpers drain the battery significantly.
