Is there a way to tell which OS X processes are using the most power over time? [duplicate]

Solution 1:

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.

Solution 2:

The answer to whether there is a similar App for OSX is yes. There are a number of them, but I'd recommend Battery Health which is available for download in the Mac App Store.

It shows cycle count, original mAh vs. current, time remaining on current charge, and processes using the most power over time:

As to whether your battery is defective is a different question. As stated by Apple, your battery is designed to retain %80 of its original full charge capacity after 1000 cycles. To obtain some helpful diagnostic information (much of same information Battery Health shows):
