Abstract

Systems and methods for profiling power cycle characteristics in a device powered at least by a battery are disclosed. In one embodiment, the method comprises the steps of: detecting a series of power cycle events, examining the series of power cycle events for at least one indication of reduced life of the battery; storing the indication; and notifying a user of the device about the indication. Each power cycle event indicates a transition between line power and battery power.

14. A method of profiling power cycle characteristics in a device powered at least by a battery, the method comprising the steps of:

detecting a series of power cycle events, each power cycle event indicating a transition between line power and battery power;

analyzing the series of power cycle events to produce at least one power cycle characteristic;

comparing the power cycle characteristic to at least one stored power cycle characteristic profile; and

storing in memory an indication of detrimental battery operation if the comparison is a match.

15. The method of 14, wherein the at least one power cycle characteristic comprises a frequency of power cycle events, a duration of a battery power interval, a total number of power cycle events, and a variation in the frequency of power cycle events.

16. (canceled)

17. The method of 14, further comprising the step of:

notifying a user of the device, through an e-mail message, of the indication of detrimental battery operation.

18. The method of 14, further comprising the step of:

notifying a user of the device, through a telephone call, of the indication of detrimental battery operation.

19. The method of 14, further comprising the steps of:

receiving a power cycle characteristics profile; and

storing the power cycle characteristics profile.

20. The method of 14, further comprising the steps of:

creating the power cycle characteristics profile based on a description of the profile.

21. A method of profiling power cycle characteristics in a device powered at least by a battery, the method comprising the steps of:

detecting a series of power cycle events, each power cycle event indicating a transition between line power and battery power;

analyzing the series of power cycle events to produce at least one power cycle characteristic;

comparing the power cycle characteristic to at least one stored power cycle characteristic profile; and

producing an indication of detrimental battery operation if the comparison is a match.

22. The method of claim 21, wherein the at least one power cycle characteristic comprises a frequency of power cycle events, a duration of a battery power interval, a total number of power cycle events, and a variation in the frequency of power cycle events.

23. The method of claim 21, further comprising the step of:

notifying a user of the device of the indication of detrimental battery operation.

24. The method of claim 21, further comprising the step of:

notifying a user of the device, through an e-mail message, of the indication of detrimental battery operation.

25. The method of claim 21, further comprising the step of:

notifying a user of the device, through a telephone call, of the indication of detrimental battery operation.

26. The method of claim 21, further comprising the steps of:

receiving a power cycle characteristics profile; and

storing the power cycle characteristics profile.

27. The method of claim 21, further comprising the steps of:

creating the power cycle characteristics profile based on a description of the profile.

28. The method of claim 21, further comprising the step of storing an indication of detrimental battery operation if the comparison is a match.
