Abstract
In order to reduce power consumption while an incoming call is detected by each of a plurality of communication methods, a mobile phone includes a radio circuit, a wireless LAN circuit, and a control portion to control power supply to them. The control portion cuts off power supply to the radio circuit when communication for a call by the wireless LAN circuit is established when power is supplied to both the radio circuit and the wireless LAN circuit.
