An apparatus for prolonging battery life in a mobile communication device comprising means for executing a search for a communication network, means for confirming that no communication network is available if the executed search is negative, means for entering into a sleep mode during which a reduced number of searches are executed if no communication network is available, means for detecting movement of the device and means for re-commencing of execution of searches for the network in dependence on movement of the device being detected. This is especially advantageous where a user will be within an area of no network coverage for a long period of time. In this case, any network search will fail and therefore shorten battery life unnecessarily. |
