1. A method for managing power data, comprising:
- determining an amount of power used for a system running an application over a first time period from an operating system;
determining an amount of power used for the system in a baseline state over a second time period from the operating system; and
determining a net power consumption of the application from the amount of power used for the system running the application and the amount of power used for the system in the baseline state.

Abstract
A method for managing power data includes determining an amount of power used for a system running an application over a first time period from an operating system. An amount of power used for the system in a baseline state over a second time period is determined from the operating system. A net power consumption of the application is determined from the amount of power used for the system running the application and the amount of power used for the system in the baseline state.
