Abstract

Techniques for power management of a portable device are described herein. According to one embodiment, a user agent of an operating system executed within a portable device is configured to monitor activities of programs running within the portable device and to predict user intent at a given point in time and possible subsequent user interaction with the portable device based on the activities of the program. Power management logic is configured to adjust power consumption of the portable device based on the predicted user intent and subsequent user interaction of the portable device, such that remaining power capacity of a battery of the portable device satisfies intended usage of the portable device.

Claims

1. A computer-implemented method, comprising:

monitoring, by a user agent of an operating system executed within a portable device, activities of a plurality of programs running within the portable device;

predicting, by the user agent, user intent at a given point in time and possible subsequent user interaction with the portable device based on the activities of the program; and

adjusting power consumption of the portable device based on the predicted user intent and subsequent user interaction of the portable device, such that remaining power capacity of a battery of the portable device satisfies intended usage of the portable device.

2. The method of claim 1, wherein the power consumption of the portable device is adjusted automatically without user intervention or knowledge.

3. The method of claim 1, wherein adjusting power consumption of the portable device comprises disabling a function of a first of the programs to reduce power consumption, if the subsequent usage of the portable device consumes more than the remaining power capacity of the battery.

4. The method of claim 1, wherein adjusting power consumption of the portable device comprises increasing performance of a second of the programs, if the subsequent usage of the portable device consumes less than the remaining power capacity of the battery.

5. The method of claim 1, wherein predicting user intent and possible subsequent user interaction with the portable device comprises communicating via an program programming interface (API) with a third program to estimate a period of time during which the portable device is without charging.

6. The method of claim 5, wherein the third program provides a travel itinerary that specifies the period of time during which the portable device could possibly operate in an airplane mode.

7. The method of claim 6, further comprising in response to a signal indicating that the portable device is operating in the airplane mode, adjusting power consumption of at least one of the programs such that the remaining power capacity of the battery can last the period of time without charging.

8. The method of claim 5, wherein the third program is a global positioning system (GPS) program indicating a location of the portable device.

9. The method of claim 8, further comprising:

determining possible actions that a user of the portable device would possibly do and how long the user would stay at the location; and

adjusting power consumption of at least one of the programs such that the remaining power capacity of the battery can last the period of time at the location without charging.

10. The method of claim 1, wherein predicting user intent and possible subsequent user interaction with the portable device comprises:

communicating via an program programming interface (API) with a fourth program to determine an ambient condition of an operating environment; and

automatically reducing backlight of a display of the portable device if the portable device operates in a dark environment.

11. A non-transitory computer-readable medium for storing instructions, which when executed by a processor, cause the processor to perform a method, the method comprising:

monitoring, by a user agent of an operating system executed within a portable device, activities of a plurality of programs running within the portable device;

predicting, by the user agent, user intent at a given point in time and possible subsequent user interaction with the portable device based on the activities of the program; and

adjusting power consumption of the portable device based on the predicted user intent and subsequent user interaction of the portable device, such that remaining power capacity of a battery of the portable device satisfies intended usage of the portable device.

12. The non-transitory computer-readable medium of claim 11, wherein the power consumption of the portable device is adjusted automatically without user intervention or knowledge.

13. The non-transitory computer-readable medium of claim 11, wherein adjusting power consumption of the portable device comprises disabling a function of a first of the programs to reduce power consumption, if the subsequent usage of the portable device consumes more than the remaining power capacity of the battery.

14. The non-transitory computer-readable medium of claim 11, wherein adjusting power consumption of the portable device comprises increasing performance of a second of the programs, if the subsequent usage of the portable device consumes less than the remaining power capacity of the battery.

15. The non-transitory computer-readable medium of claim 11, wherein predicting user intent and possible subsequent user interaction with the portable device comprises communicating via an application programming interface (API) with a third program to estimate a period of time during which the portable device is without charging.

16. The non-transitory computer-readable medium of claim 15, wherein the third program provides a travel itinerary that specifies the period of time during which the portable device could possibly operate in an airplane mode.

17. The non-transitory computer-readable medium of claim 16, wherein the method further comprises in response to a signal indicating that the portable device is operating in the airplane mode, adjusting power consumption of at least one of the programs such that the remaining power capacity of the battery can last the period of time without charging.

18. The non-transitory computer-readable medium of claim 15, wherein the third program is a global positioning system (GPS) program indicating a location of the portable device.

19. The non-transitory computer-readable medium of claim 18, the method further comprises:

determining possible actions that a user of the portable device would possibly do and how long the user would stay at the location; and

adjusting power consumption of at least one of the programs such that the remaining power capacity of the battery can last the period of time at the location without charging.

20. A portable device, comprising:

a user agent to monitor activities of a plurality of programs running within the portable device and to predict user intent at a given point in time and possible subsequent user interaction with the portable device based on the activities of the program; and

power management logic coupled to the user agent to adjust power consumption of the portable device based on the predicted user intent and subsequent user interaction of the portable device, such that remaining power capacity of a battery of the portable device satisfies intended usage of the portable device.

21. The portable device of claim 20, wherein the power consumption of the portable device is adjusted automatically without user intervention or knowledge.

22. The portable device of claim 20, wherein adjusting power consumption of the portable device comprises disabling a function of a first of the programs to reduce power consumption, if the subsequent usage of the portable device consumes more than the remaining power capacity of the battery.

23. The portable device of claim 20, wherein adjusting power consumption of the portable device comprises increasing performance of a second of the programs, if the subsequent usage of the portable device consumes less than the remaining power capacity of the battery.

24. The portable device of claim 20, wherein predicting user intent and possible subsequent user interaction with the portable device comprises communicating via an program programming interface (API) with a third program to estimate a period of time during which the portable device is without charging.
