A method and an apparatus for waking up a device are disclosed by embodiments of the present invention, relating to the field of communications, and capable of improving user experience in a device wake-up process. A specific solution is: when a timing interval of a timer is equal to a preset threshold, detecting, by a first device, whether a second device transmits a radio signal, where the first device is a device waked up by the second device; when the radio signal is detected, transmitting, by the first device, a first message to the second device, so that the second device switches to a station STA mode after receiving the first message, where the first message is used to notify the second device that the first device is waked up successfully; switching, by the first device, to an access point AP mode, so that the second device implements wireless fidelity Wi-Fi access through the first device; and when the radio signal is not detected, disabling, by the first device, the Wi-Fi, and restarting the timer. The present invention is used in a device wake-up process. |
