Abstract

A mobile telephone able to save power in response to the position of the mobile telephone is disclosed. Location circuitry within the mobile telephone enables the establishment of one or more deep-sleep locations associated with a mobile telephone. When the location circuitry determines that the current location of the mobile telephone is within a selected distance of one of the deep-sleep locations, the mobile telephone operates according to a low power mode of operation wherein only a timer enabling periodic updates of the mobile telephone's position is active. If the location circuitry determines that the mobile telephone is not within a selected distance of one of the predetermined locations, the mobile telephone operates in a standby mode which utilizes more power than the deep-sleep mode but still conserves battery power and enables the mobile telephone to receive calls.
