The electronic device includes a location measurement module configured to measure a location; a memory configured to store an application program; and a processor electrically connected to the location measurement module and the memory, wherein the memory stores instructions that, when executed, cause the processor to store location information obtained by the location measurement module in the memory, process a request from the application program to obtain location information, and, in response to the request to obtain location information, provide the stored location information to the application program based on at least part of the location information stored in the memory.
System and method for maximizing mobile device power using intelligent attribute selection
A mobile application tracks a user's behavior and activities and, in particular, a geo-location. The mobile application may then produce a profile of the user's behaviors and locations. This may be used to optimize mobile device power and may also be used as a data aggregator to collect and gather user information for other purposes, such as data marketing and modeling. In an embodiment, the mobile application is continuously monitoring the mobile device's battery level and power usage and determining the most power-efficient approach for tracking the device's location. One-hundred percent location accuracy is not always required when profiling a user's behavior. It may be more critical to simply determine the general location of the device and the associated user. The application may continuously function in the background while expending the least amount of power possible.

Power-efficient location estimation
A wireless computing device may scan a frequency set. A first group of base stations may use the frequencies in the frequency set. Based on information relating to one or more base stations in the first group of base stations, the wireless computing device may estimate its location. The wireless computing device may further select a frequency subset of the frequency set. A second group of base stations may use the frequencies of the frequency subset. Based on information relating to one or more base stations in the second group of base stations, the wireless computing device may again estimate its location. If the two estimated locations are within a threshold distance of one another, the wireless computing device may perform, during a subsequent location-estimating operation, an additional frequency scan using the frequency subset.
