Method and apparatus for managing battery power in response to an indication of an application being scheduled for immediate execution

摘要

Techniques for managing battery power of a mobile device are described. In an aspect, battery power may be reserved for an application prior to execution of the application on the mobile device. The reservation may ensure that the application has sufficient battery power for execution. In another aspect, battery power may be allocated to applications based on their priorities. The applications may be ordered based on their priorities, and the available battery power for the mobile device may be allocated to one application at a time, starting with the highest priority application. In yet another aspect, battery power may be allocated to applications based on a battery discharge curve for the mobile device. An operating point on the battery discharge curve may be selected based on at least one objective. The available battery power may be determined based on the selected operating point and allocated to the applications.

主权项

1. A method of managing battery power, comprising:
receiving an indication of an application being scheduled for immediate execution on a mobile device; determining available battery power for the mobile device; determining required battery power for the application without user input; and reserving battery power for the application prior to executing the application on the mobile device, wherein the determining required battery power for the application comprises: identifying at least one subsystem of the mobile device used by the application, estimating battery power consumed by the at least one subsystem to support the application, and determining the required battery power for the application based on the estimated battery power consumed by the at least one subsystem to support the application, and wherein the estimating battery power consumed by the at least one subsystem to support the application comprises: identifying a subsystem used by the application and at least one active application, the subsystem being one of the at least one subsystem supporting the application, and estimating battery power consumed by the subsystem to support the application based on a difference between total battery power consumed by the subsystem to support the application and the at least one active application and battery power consumed by the subsystem to support the at least one active application.
