Power Awareness in Mobile Applications

The patent introduces a power management intermediary layer that sits between applications and power-consuming components. This intermediary collects power consumption data from hardware components, processes it centrally, and provides simplified power awareness information to applications. This mediator approach enables power optimization without requiring each application to implement complex monitoring logic, thus resolving the contradiction between improved power awareness and increased system complexity.

The patent implements dynamic operation scheduling where applications can adaptively defer or execute operations based on real-time power conditions and user-defined preferences. The system provides a spectrum of options from immediate execution to deferred execution, allowing applications to dynamically adjust their operational timing. This dynamic approach enables battery life extension while maintaining operational productivity by allowing critical operations to execute promptly and non-critical operations to be deferred when power is low.

The patent implements preliminary action by allowing applications to register interest in power-consuming components in advance and receive notifications when components become available. Instead of continuously polling or blocking waits, applications can preemptively set up notification mechanisms. When power conditions are favorable and components become available, applications are notified and can execute operations promptly. This approach optimizes power consumption by avoiding continuous monitoring while maintaining responsive execution when conditions permit.
