A method and apparatus for reducing battery drain in a mobile station of a radio communication system characterizes and stores the radio environment in which it failed to acquire synchronization with the system. The mobile station then enters a low power mode for a predetermined time duration. Upon exiting the low power mode, the mobile station determines if the radio environment has changed by more than a predetermined threshold. If so, the mobile station will re-attempt initial synchronization. |
