Power management system and method for controlling use of power-consuming applications

An electronic device having a power management system, the electronic device comprising:

• a battery for providing power to the electronic device;
• a processor for executing applications, where the executing applications are assigned predetermined prioritization;
• and
• a power management module configured to dynamically control use of at least one of the executing application that is a power-consuming element of the electronic device based at least on the predetermined prioritization to enable use of the electronic device for a requested duration based at least on an amount of power available from the battery powering the electronic device.

A method for managing power consumption in an electronic device, the method comprising:

• receiving a requested duration of time for powering the electronic device by a battery and storing the requested duration in a memory;
• assigning, by a processor in the electronic device, a priority to each executable application from a plurality of executable applications that when executed by a processor cause the processor to consume battery power;
• executing, by the processor, one or more of the executable applications in the electronic device;
• determining, by the processor, an estimated battery power duration based at least on analyzing the battery and power draw conditions from the executing applications;
• and
• if the estimated battery power duration is below the requested duration of time, ceasing execution, by the processor, of one or more of the executing applications that have a lower priority than other executing applications.
