1. A system that facilitates dynamic power management, comprising: a portable multi-modal device including an onboard power source that provides power to portable multi-modal device during normal operation of the portable multi-modal device, a context determination component that determines, independent of a user action, a context based at least in part on at least one of external environment data or internal application data, and a power/mode management component including a power conservation component that dynamically enables an alternate power source based at least in part on the context in order to supplement the onboard power source and place the portable multi-modal device in a low power consumption state.
9. The system of claim 1 , wherein the context is inferred using one of probabilistic or statistical-based analysis.
