Abstract

Various computing devices and methods of managing the power consumption thereby are disclosed. In one aspect, a method of managing power consumption of a computing device that has a battery is provided. The method includes cycling the computing device between a connected standby active state and a connected standby idle state. The duration of the connected standby idle state is set based at least in part on a charge level of the battery.

Claims

1. A method of managing power consumption of a computing device having a battery, comprising:

cycling the computing device between a connected standby active state and a connected standby idle state; and

setting the duration of the connected standby idle state based at least in part on a charge level of the battery.

2. The method of claim 1, wherein the duration is increased when the battery charge level falls to a selected level.

3. The method of claim 1, comprising running an application on the computing device and instructing the application to limit its activities to the connected standby active state.

4. The method of claim 3, comprising preventing the application from activity during the connected standby idle state.

5. The method of claim 3, comprising setting a quality of service level of the application.

6. The method of claim 3, wherein the application is operable to cause the computing device to communicate with a network device, the method including causing the application to communicate the battery charge level to the network device and modifying the interaction between the computing device and the network device in response to the communicated battery charge level.

7. The method of claim 1, comprising setting the duration of connected standby idle state based at least in part on a temperature of the computing device.

8. The method of claim 1, comprising setting the duration of the connected standby idle state based at least in part on an anticipated elapsed time before the battery is recharged.

9. The method of claim 1, wherein the computing device includes a connected standby controller operable to sense wake up events, the method including having the connected standby controller selectively mask off some wake up events and leave other wake up events unmasked based at least in part on the battery charge level.

10. The method of claim 9, comprising counting assertions of an unmasked wake up event and enabling the wake up event to cause exit of the connected standby idle state if the number of assertions exceeds a selected threshold.

11. A computing device, comprising:

a battery; and

a connected standby controller programmed to cycle the computing device between a connected standby active state and a connected standby idle state, and set the duration of the connected standby idle state based at least in part on a charge level of the battery.

12. The computing device of claim 11, wherein connected standby controller is operable to increase the duration when the battery charge level falls to a selected level.

13. The computing device of claim 11, comprising an application on the computing device, the connected standby controller being operable to instruct the application to limit its activities to the connected standby active state.

14. The computing device of claim 13, wherein the connected standby controller is operable to prevent the application from engaging in activity during the connected standby idle state.

15. The computing device of claim 13, wherein the connected standby controller is operable to set a quality of service level of the application.

16. The computing device of claim 13, wherein the application is operable to cause the computing device to communicate with a network device, the connected standby controller being operable to cause the application to communicate the battery charge level to the network device and modifying the interaction between the computing device and the network device in response to the communicated battery charge level.

17. The computing device of claim 11, wherein the connected standby controller is operable to set the duration of connected standby idle state based at least in part on a temperature of the computing device.

18. The computing device of claim 11, wherein the connected standby controller is operable to set the duration of the connected standby idle state based at least in part on an anticipated elapsed time before the battery is recharged.

19. The computing device of claim 11, wherein the connected standby controller is operable to sense wake up events, selectively mask off some wake up events and leave other wake up events unmasked based at least in part on the battery charge level.

20. The computing device of claim 19, wherein the connected standby controller is operable to count assertions of an unmasked wake up event and enable the wake up event to cause exit of the connected standby idle state if the number of assertions exceeds a selected threshold.

21. A computer readable medium having computer readable instructions for performing a method comprising:

managing power consumption of a computing device having a battery by cycling the computing device between a connected standby active state and a connected standby idle state, and setting the duration of the connected standby idle state based at least in part on a charge level of the battery.
