1. A method, comprising acts of: monitoring power consumption of a mobile device of a first user during user navigation along geographical routes using a map application; accessing, via the mobile device of the first user, metadata of a second user stored on a network as location updates, the metadata comprising speed data and vector data, and stored on the network as the second user navigates along geographical routes using a map application; estimating according to a probable location approximation via the mobile device of the first user, a realtime geographical location of the second user based on the accessed metadata, the estimating performed at the mobile device to conserve power in the mobile device based on location update importance, the power conserved by periodically accessing the network for additional location updates of the second user rather than expending power by continuously accessing the network for the additional location updates of the second user; and configuring a microprocessor to execute instructions stored in a memory, the instructions related to the acts of monitoring, accessing, and estimating.
