A wake-up method for a receiver is performed by an electronic device, the electronic device having a first receiver and a main transceiver, with operating power consumption of the first receiver lower than operating power consumption of the main transceiver. The method includes: receiving a first power-saving signal, the first power-saving signal being used to indicate whether to wake up the first receiver; and receiving a second power-saving signal, the second power-saving signal being used to indicate whether to wake up the main transceiver.
