Abstract

System and methods to determine the energy consumption per event type from usage data of portable devices are described. An example method includes determining a first plurality of linear equations representative of energy expended in a portable device for a second plurality of functions, the second plurality of functions including at least one software function of the portable device, the first plurality being more than the second plurality, and determining, using a processor, energy values corresponding to the second plurality of functions by applying a statistical method to the first plurality of linear equations.

Claims

1. A method to determine energy usage of a portable device, the method comprising:

determining a first plurality of linear equations representative of energy expended in a portable device for a second plurality of functions, the second plurality of functions including at least one software function of the portable device, the first plurality being more than the second plurality; and

determining, using a processor, energy values corresponding to the second plurality of functions by applying a statistical method to the first plurality of linear equations.

2. A method as defined in claim 1, wherein the statistical method comprises a least squares fit.

3. A method as defined in claim 1, wherein at least one of variables or inputs of the first plurality of linear equations include lengths of time spent performing the second plurality of functions.

4. A system to determine the energy usage of a portable device, the system comprising:

a data analyzer to;

determine a first plurality of linear equations representative of energy expended in at least a portion of a portable device for a second plurality of functions, the second plurality of functions including at least one software function of the portable device, the first plurality being greater than the second plurality; and

apply a statistical method to the first plurality of linear equations to determine energy consumption values corresponding to the second plurality of functions.

5. A system as defined in claim 4, wherein the statistical method comprises a least squares fit.

6. A system as defined in claim 4, wherein at least one of variables or inputs of the first plurality of linear equations include lengths of time spent performing the second plurality of functions.

7. A tangible computer readable storage medium comprising computer readable instructions which, when executed, cause a processor to at least:

determine a first plurality of linear equations representative of energy expended in a portable device for a second plurality of functions, the second plurality of functions including at least one software function of the portable device, the first plurality being more than the second plurality; and

determine, using a processor, energy values corresponding to the second plurality of functions by applying a statistical method to the first plurality of linear equations.

8. A storage medium as defined in claim 7, wherein the statistical method comprises a least squares fit.

9. A storage medium as defined in claim 7, wherein at least one of variables or inputs of the first plurality of linear equations include lengths of time spent performing the second plurality of functions.
