Abstract

A method of operating a mobile device comprises operating the mobile device in a low power mode, switching the mobile device to a high power mode in response to an event, identifying the event as specific type of event, selecting a time period according to the identified type of event, preventing an algorithm for switching the mobile device to the low power mode from executing, for the time period, and (ultimately) executing the algorithm.

Claims

1. A method of operating a mobile device comprising:

operating the mobile device in a low power mode,

switching the mobile device to a high power mode, in response to an event,

identifying the event as specific type of event,

selecting a time period according to the identified type of event,

preventing an algorithm for switching the mobile device to the low power mode from executing, for said time period, and

executing said algorithm.

2. A method according to claim 1, and further comprising, while said algorithm is prevented from executing, detecting a second event, identifying the second event as specific type of event, and selecting a new time period according to the identified type of event.

3. A method according to claim 2, wherein the new time period comprises the sum of the time period associated with the first event and the time period associated with the second event.

4. A method according to claim 2, wherein the new time period comprises the time period associated with the second event.

5. A method according to claim 2, wherein the new time period comprises the longer of the time period associated with the first event and the time period associated with the second event.

6. A method according to claim 1, wherein the types of events comprise key operations, display updates, incoming communications and processor pending events.

7. A mobile device comprising a processor and a power mode control system, wherein the processor is arranged to operate in a low power mode, and the power mode control system is arranged to switch the processor to a high power mode, in response to an event, to identify the event as specific type of event, to select a time period according to the identified type of event, to prevent an algorithm for switching the mobile device to the low power mode from executing, for said time period, and to execute said algorithm.

8. A device according to claim 7, wherein the power mode control system is further arranged, while said algorithm is prevented from executing, to detect a second event, to identify the second event as specific type of event, and to select a new time period according to the identified type of event.

9. A device according to claim 8, wherein the new time period comprises the sum of the time period associated with the first event and the time period associated with the second event.

10. A device according to claim 8, wherein the new time period comprises the time period associated with the second event.

11. A device according to claim 8, wherein the new time period comprises the longer of the time period associated with the first event and the time period associated with the second event.

12. A device according to claim 7, wherein the types of events comprise key operations, display updates, incoming communications and processor pending events.
