Abstract

A battery-operated computing device collects data on battery power draw, and logs events and user actions occurring during device operation. A time profile or graph of the battery power draw is displayed on the computing device. The displayed time profile or graph of battery power draw is overlaid with markers or indicators of the logged events or user actions to highlight power hogging events or actions.

Claims

1. A battery-operated computing device, comprising:

a processor;

a battery monitor configured to provide a time profile of battery power draw in the operation of the computing device;

an event logger configured to record events occurring in the operation of the computing device;

an overlay generator coupled to the battery monitor and the event logger, and configured to generate a graph showing time in a first axis and battery power draw in a second axis with text indicators describing the events at times that the events occurred; and

a display configured to display the generated graph.

2. The computing device of claim 1 that is configured as one of a battery-operated laptop or tablet computer, a digital camera, a personal digital assistant, a mobile phone, a smartphone, and/or a multimedia player.

3. The computing device of claim 1, wherein the overlay generator is further configured to present the graph on the display in the computing device.

5. The computing device of claim 3, wherein the overlay generator is programmable and allows designation of events as interesting, and wherein the overlay generator is further configured to overlay the graph with indicators describing the events that have been designated as interesting.

6. The computing device of claim 5, wherein the overlay generator is further configured to highlight events that caused increases in battery power draw above a threshold percent.

7. The computing device of claim 5, wherein the overlay generator is further configured to highlight events that failed to cause increases in battery power draw above a threshold percent.

8. The computing device of claim 1, wherein the battery monitor is further configured to sample battery power draw in the operation of the computer device periodically.

9. The computing device of claim 1, wherein the event logger is programmable, and wherein the event logger is programmed to log computer or application initiated actions and/or user initiated actions during operation of the computing device.

10. The computing device of claim 9, wherein the event logger is programmed to log selected events, and wherein the selected events include one or more of opening or closing of tabs in a web browser, navigating to or away for a particular website, pop-ups, starting or stopping audio, starting or stopping video, transitions between 3G, Wi-Fi, or Ethernet communications, user-triggered or automatic display brightness circuitry responses to ambient light changes, keystrokes, and/or activation or closing of applications.

overlaying the displayed graph with text indicators describing the logged events at times that the logged events occurred.

12. The method of claim 11, wherein logging events occurring in the operation of the computing device includes recording and time-stamping one or more events occurring in the operation of the computing device.

13. The method of claim 11, wherein displaying a time profile of the battery power draw during operation of the computing device includes displaying the time profile on a display in the battery-operated computing device.

14. The method of claim 11, further comprising, designating particular events in the operation of the computing device as interesting and overlaying the displayed graph with the text indicators at the times that the interesting events occurred during the operation the computing device.

15. The method of claim 14, wherein designating particular events in the operation of the computing device as interesting comprises designating as interesting one or more opening or closing of tabs in a web browser, navigating to or away for a particular website, pop-ups, starting or stopping audio, starting or stopping audio, transitions between 3G, Wi-Fi, or Ethernet communications, user-triggered or automatic display brightness circuitry responses to ambient light changes, keystrokes, and/or activation or closing of applications.

16. The method of claim 11, further comprising, reporting collected battery power draw data and a log of one or more the events to a remote device.
