Abstract
A detecting method and a detecting device for saving electrical power consumption of a communication device are introduced. During each operation cycle, a receiving end is switched between a hibernation mode and an operation mode alternately. The receiving end in the hibernation mode is supplied with a first electric power, the receiving end in the operation mode is supplied with a second electric power, and the first electric power is smaller than the second electric power. The receiving end in the operation mode detects whether there is a first signal from a sending end. If receiving the first signal, the receiving end is kept in the operation mode, and continued to be supplied with the second electric power. If the receiving end in the operation mode does not receive the first signal, the receiving end enters the hibernation mode and is supplied with the first electric power.
