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.

Claims

1. A method comprising:

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

analyzing, by a computing device that includes at least one processor, 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, which includes an average frequency of transitions to battery characteristic, an average interval between transitions to battery characteristic, and a total number of transitions to battery characteristic; and

storing in memory an indication of detrimental battery operation if the comparison is a match, wherein a determination is made whether to notify an individual of the detrimental battery operation based on settings provided by the individual, and wherein an e-mail notification is provided to the individual to identify the detrimental battery operation.

2. The method of 1, 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.

3. The method of 1, further comprising the step of:

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

4. The method of 1, further comprising the steps of:

receiving a power cycle characteristics profile; and

storing the power cycle characteristics profile.

5. The method of 1, further comprising the steps of:

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

6. A method comprising:

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

analyzing, by a computing device that includes at least one processor, 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, which includes an average frequency of transitions to battery characteristic, an average interval between transitions to battery characteristic, and a total number of transitions to battery characteristic; and

producing an indication of detrimental battery operation if the comparison is a match, wherein a determination is made whether to notify an individual of the detrimental battery operation based on settings provided by the individual, and wherein an e-mail notification is provided to the individual to identify the detrimental battery operation.

7. The method of claim 6, 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.

8. The method of claim 6, further comprising the step of:

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

9. The method of claim 6, further comprising the step of:

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

10. The method of claim 6, further comprising the steps of:

receiving a power cycle characteristics profile; and

storing the power cycle characteristics profile.

11. The method of claim 6, further comprising the steps of:

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

12. The method of claim 6, further comprising the step of storing an indication of detrimental battery operation if the comparison is a match.
