Abstract:
Managing use of a location sensor on a computing device for energy efficiency. The location sensor is briefly initialized to measure the signal quality. The measured signal quality is compared to pre-defined signal criteria values. The signal criteria values correspond to acceptable energy consumption, for example. If the signal criteria values are satisfied, location information for the computing device is obtained. Otherwise, the location sensor is disabled without obtaining the location information. In some embodiments, a lower-energy location sensor is used to obtain location information to determine whether to enable a higher-energy location sensor based on expected energy consumption.
