Is there a way to tell which OS X processes are using the most power over time? My Android phone comes installed w/ an app that graphs out power usage of various components over time, so it's clear that the screen is the biggest user, followed by the phone, followed by Facebook etc. 

Is there a similar app for the MacBook?  I'm following best practices yet only getting a couple of hours of time out of a new (reconditioned) 2013 Macbook Pro (Mt Lion) with a battery showing only 10 cycles and near max health on it.  

Thanks
Activity Monitor has this feature. It can chart power consumption per process in the Energy tab. You can find it in /Applications/Utilities/Activity Monitor.app.
