Abstract

Techniques for conserving battery power in devices are provided. One or more deferrable tasks are queued for later execution. An initiation of a subsequent charging event for a battery of the device is detected. The queued deferrable task(s) are enabled to be executed during the charging event. For instance, the queued deferrable task(s) may be enabled to be executed if the charging event is predicted to be a long duration charging event, such as by referring to a charging profile of the mobile device. In this manner, battery power is conserved while the device is in use and not connected to a battery charger.

Claims

1. A method in a device, comprising:

queuing at least one deferrable task for later execution;

detecting an initiation of a charging event for a battery of the device subsequent to said queuing; and

enabling the queued at least one deferrable task to be executed during the charging event.

2. The method of claim 1,

predicting that the charging event is a long duration charging event based on a charging profile for the device;

and

enabling said executing as a result of said predicting.

3. The method of claim 2, wherein said predicting comprises:

predicting that the charging event has a duration greater than a predetermined threshold.

4. The method of claim 2, further comprising:

monitoring a charging of the battery of the device over time; and

generating the charging profile based on said monitoring.

5. The method of claim 2, further comprising:

enabling a user of the device to manually configure the charging profile.

6. The method of claim 1, further comprising:

receiving a request to execute a particular task;

determining that the particular task is not deferrable; and

enabling the particular task to be executed prior to the charging event.

7. The method of claim 1, further comprising:

queuing a deferrable task associated with a file for later execution;

receiving a request from a user related to the file;

removing the deferrable task from the queue due to the received request; and

performing an operation with regard to the file as a result of the received request.

8. The method of claim 1, further comprising:

performing a lightweight scan on a file to generate a scan result;

transmitting the scan result to a remote server;

receiving an indication from the remote server whether the file is malicious; and

queuing a full scan task associated with the file if the file is indicated to not be malicious.

9. The method of claim 1, wherein the at least one deferrable task includes at least one of a file download task, a virus scan task, a backup task, or a configuration management task.

20. The computer program product of claim 1, wherein the fourth means comprises:

means for enabling the processing unit to predict that the charging event is a long duration charging event based on a charging profile for the device; and

means for enabling the processing unit to enable the queued at least one deferrable task to be executed as a result of the prediction.

10. A task scheduler in a mobile device, the task scheduler enabling conserving of battery power of the mobile device during mobile operation, the task scheduler, comprising:

a task queuing module configured to determine that at least one task is deferrable and to queue the at least one deferrable task for later execution;

a charge monitor configured to detect an initiation of a charging event for a battery of the mobile device subsequent to queuing the at least one deferrable task; and

a queue enabler module configured to enable the at least one deferrable task to be executed during the charging event if the charging event is predicted to be a long duration charging event.

11. The task scheduler of claim 10, wherein the queue enabler module comprises:

a charge event analyzer configured to predict that the charging event is a long duration charging event based on a charging profile for the mobile device; and

the queue enabler module being configured to enable the queued at least one deferrable task to be executed during the charging event as a result of the prediction.

12. The task scheduler of claim 11, wherein the charge event analyzer is configured to determine whether the charging event has a duration greater than a predetermined threshold to predict whether the charging event is a long duration charging event.

13. The task scheduler of claim 11, wherein the queue enabler module is configured to monitor a charging of the battery over time to generate charge history data, and to generate the charging profile based on the charge history data.

14. The task scheduler of claim 11, further comprising:

a user interface module configured to enable a user of the mobile device to manually configure the charging profile.

15. The task scheduler of claim 10, wherein the task queuing module receives a request to execute a particular task, and determines whether the particular task is not deferrable, the queue enabler module enabling the particular task to be executed prior to receiving the charge current if the particular task is determined to be not deferrable.

16. The task scheduler of claim 10, wherein the task queuing module queues a deferrable task associated with a file for later execution, receives a request from a user related to the file, and removes the deferrable task associated with the file from the queue due to the received request.

17. The task scheduler of claim 10, wherein a scanning module of the mobile device performs a lightweight scan on a file to generate a scan result, and the scan result is transmitted from the mobile device to a remote server;

the task queuing module being configured to queue a full scan task associated with the file if the file is indicated to not be malicious in a response received from the remote server.

18. The task scheduler of claim 10, wherein the at least one deferrable task includes at least one of a file download task, a virus scan task, a backup task, or a configuration management task.

19. A computer program product comprising a computer usable storage medium having computer readable logic embodied in said storage medium for enabling a processing unit to perform battery management for a device, comprising:

first means for enabling the processing unit to queue at least one deferrable task for later execution;

second means for enabling the processing unit to detect an initiation of a charging event for a battery of the device subsequent to the at least one deferrable task being queued; and

third means for enabling the processing unit to enable the queued at least one deferrable task to be executed during the charging event.
