POWER CONSERVATION TECHNIQUES FOR USE IN DEVICES WITH SELECTABLE POWER MODES

Techniques are provided which may be implemented in various methods, apparatuses, and/or articles of manufacture for use in and/or with an electronic device that is operable in a plurality of selectable power modes, including at least a "higher power mode" and a "lower power mode". In an example implementation, with an electronic device operating in a higher power mode may selectively transition to a lower power mode based, at least in part, on at least phase value obtained from a signal acquired from a ground-based transmitter. Further techniques are provided which may be implemented to allow electronic device to selectively transition from a lower power mode to one or more other selectable power modes, e.g., including various "medium power modes", and various "higher power modes".
