Abstract

The present invention provides a system and method for extending the battery life of a mobile device. The method of extending the battery life of a mobile device can be broadly summarized by the following steps of determining if at least one component on the mobile device can be placed in a hibernation state for a predetermined time, setting a remote clock to the current time, and powering off the at least one component on the mobile device that can be placed in the hibernation state. The method further includes waiting a predetermined interval, re-activating the at least one component on the mobile device that was placed in the hibernation state, and synchronizing a system clock with the remote clock.

Claims

1. A method for extending the battery life of a mobile device, comprising the steps of:

determining if at least one component on the mobile device can be placed in a hibernation state for a predetermined time;

setting a remote clock to the current time;

powering off the at least one component on the mobile device that can be placed in the hibernation state;

waiting a predetermined interval;

re-activating the at least one component on the mobile device that was placed in the hibernation state; and

synchronizing a system clock with the remote clock.

2. The method of claim 1, wherein the mobile device is a GPS tracking device.

3. The method of claim 2, wherein the step of powering off of the at least one component is performed after determining that the GPS tracking device is unable to obtain a GPS position for the GPS tracking device.

4. The method of claim 2, wherein the step of powering off of the at least one component is performed after determining that the GPS tracking device is unable to establish a communication link to transmit GPS position data.

5. The method of claim 1, wherein the mobile device is a communication device.

6. The method of claim 5, wherein the communication device is a wireless telephone.

7. The method of claim 1, wherein the mobile device is a mobile computing device.

8. A system that provides for extending the battery life of a mobile device, comprising:

a priority determination module that determines if at least one component on the mobile device can be placed in a hibernation state for a predetermined time;

a remote clock that is set to the current time of a system clock;

a deactivate module that powers off the at least one component on the mobile device that can be placed in the hibernation state; and

an interrupt routine that reactivates the at least one component on the mobile device that was placed in the hibernation state after waiting a predetermined interval and synchronizes the system clock with the remote clock.

9. The system of claim 8, wherein the mobile device is a GPS tracking device.

10. The system of claim 9, wherein the priority determination module further determines if the GPS tracking device is unable to obtain a GPS position for the GPS tracking device.

11. The system of claim 9, wherein the priority determination module further determines if the GPS tracking device is unable to establish a communication link to transmit GPS position data.

12. The system of claim 8, wherein the mobile device is a communication device.

13. The system of claim 12, wherein the communication device is a wireless telephone.

14. The system of claim 8, wherein the mobile device is a mobile computing device.

15. A computer program product for extending the battery life of a mobile device, the computer program product comprising:

a tangible storage medium readable by the mobile device and storing instructions for execution by the mobile device for performing a method comprising;

determining if at least one component on the mobile device can be placed in a hibernation state for a predetermined time;

setting a remote clock to the current time;

powering off the at least one component on the mobile device that can be placed in the hibernation state;

waiting a predetermined interval;

re-activating the at least one component on the mobile device that was placed in the hibernation state; and

synchronizing a system clock with the remote clock.

16. The computer program product of claim 15, wherein the mobile device is a GPS tracking device.

17. The computer program product of claim 16, wherein the powering off of the at least one component is performed after determining that the GPS tracking device is unable to obtain a GPS position for the GPS tracking device.

18. The computer program product of claim 15, wherein the step of powering off of the at least one component is performed after determining that the GPS tracking device is unable to establish a communication link to transmit GPS position data.

19. The computer program product of claim 15, wherein the mobile device is a communication device.

20. The computer program product of claim 19, wherein the mobile device is a mobile computing device.
