A device (200) and method (300) of saving energy in a wireless communication device (200) capable of running on a wide area network and a local area network, are disclosed. The method (300) can include: operating (310) on a wide area network and a local area network, defining an active mode, wherein neighbor cell measurements are made at a first scanning interval; detecting (320) conditions to transition to a dormant mode, by: a) operating on the local area network, b) entering a scheduled quiet time, and c) determining a quality of service from the local area network meets a predetermined threshold; and transitioning (330) to a dormant mode wherein the neighbor cell measurements are made at a second scanning interval, reduced from the first scanning interval.
