Abstract: Methods, systems, and portable devices which reduce the power used by a portable device to receive/process satellite navigational system signals and/or to compute the portable device's position using satellite navigational system signals are provided. A method includes retrieving information concerning power usage characteristics based on aggregate data corresponding to a current location of the portable device; and selecting a power saving mode based on the retrieved power usage information from the aggregate data, where each of the plurality of power saving modes reduces power usage in at least one of receiving the satellite navigational system signals, processing the satellite navigational system signals, and computing the portable device's position using the satellite navigational system signals.
