Embodiments of the present invention relate to a method and an apparatus for reducing power. The method includes: identifying, by a wireless communications module included in a communications device, when a Wireless Fidelity Wi-Fi mode of the communications device is already enabled, whether service data to be sent exists currently; acquiring, by the wireless communications module, received attribute information if the service data exists currently; determining, by the wireless communications module by using the received attribute information, a sending rate for sending the service data; and determining, by the wireless communications module according to the sending rate, a supply voltage value of a power amplifier connected to the wireless communications module, so that the power amplifier amplifies, according to the supply voltage value, a service request signal carrying the service data. |
