Abstract

Event triggered snapshots of display content of software applications facilitate for a user, typically in the role of a software application developer, in the process of power-optimising an application under development. The invention provides the developers with an ability to correlate specific software application events, e.g. user interface events, to power consumption peaks and lows.

Claims

1. A method for monitoring power consumption in a mobile battery operated device, the device comprising electric circuitry, a display and a battery, the method comprising the steps of:

executing a software application, during which the software application at least generates display content,

detecting, at a plurality of instants of time, at least one electric quantity representative of power output from the battery,

detecting at least one triggering event, and

in response to the at least one triggering event, recording at least a respective subset of the display content generated by the software application.

2. The method according to claim 1, wherein the step of detecting at least one triggering event comprises detecting a signal generated via said electric circuitry in response to a user action.

3. The method according to claim 2, wherein the detection of a signal comprises detecting a signal from a keypad.

4. The method according to claim 1, wherein the at least one triggering event is generated by way of analysing a plurality of said at least one electric quantity representative of power output in terms of any of peak values, gradients and changes of gradients.

5. The method according to claim 1, wherein the step of detecting at least one triggering event comprises detecting a timing signal.

6. The method according to claim 1, further comprising the step of:

displaying the recorded display content.

7. The method according to claim 6, wherein the displaying of the display content is performed in response to the at least one triggering event.

8. The method according to claim 1, further comprising the step of:

displaying power level indicators representative of the at least one detected electric quantity representative of power output.

9. The method according to claim 8, wherein the displaying of power level indicators comprises displaying a graph of power level indicators with respect to time.

10. The method according to claim 8, further comprising displaying a graphic triggering event indicator corresponding to a point in time associated with a detected triggering event.

11. The method according to claim 8, comprising blending the displaying of the display content and the displaying of the power level indicators.

12. The method according to claim 1, further comprising the step of:

recording the at least one detected electric quantity representative of power output in the form of a time series of values.

13. The method according to claim 12, further comprising the step of:

providing the recorded time series of values for use in an analysis system.

14. The method according to claim 1, further comprising the step of:

recording a respective time point associated with each recorded display content.

15. The method according to claim 14, further comprising the step of:

providing the recorded time points and the respective recorded display content for use in an analysis system.

17. A computer program comprising software instructions that, when executed in a communication terminal, performs the method according to claim 1.

16. A mobile battery operated device configured for monitoring power consumption, the device comprising electric circuitry, a display and a battery, the terminal comprising:

means for executing a software application, during which the software application at least generates display content,

means for detecting, at a plurality of instants of time, at least one electric quantity representative of power output from the battery,

means for detecting at least one triggering event, and

means for, in response to the at least one triggering event, recording at least a respective subset of the display content generated by the software application.
