Abstract: The present invention provides a wireless device and method for reducing standby power. The method for reducing standby power of the wireless device includes the steps of: charging a charging battery with power supplied from an AC commercial power source in a normal mode of the wireless device, blocking the power of the AC commercial power source and converting an operation state of the wireless device so that the wireless device is in a standby mode when an operation-off signal used for turning off a predetermined device is transmitted from an outside. In this case, the wireless device receives the power with which the charging battery has been charged. In a standby mode, the wires device is periodically converted to be in a normal mode to transmit an operation state inquiry signal to the outside, so that it is possible to normally control the predetermined device.
