Standby power consumption of a mobile device is an important component of its overall power consumption. During standby, mobile devices periodically wake up to communicate with the network to exchange information pertaining to serving base stations, neighboring base stations, etc. which consumes power without any actual call or data activity. This disclosure describes techniques to reduce the standby power consumption of a mobile device. Location (latitude and longitude) information derived from a geolocation receiver such as GPS, GLONASS, or BeiDou is used by the mobile device to modify the frequency for performing network search, e.g., the frequency of network search is reduced if the mobile is determined to be substantially stationary. The techniques use an existing geolocation receiver in a mobile device, e.g., without additional hardware cost, and are applicable to a wide variety of air interface protocols.
