1. A method for setting a sleep mode in a wireless power receiver that may receive wireless charging power from a wireless power transmitter, comprising:
- receiving wireless charging power from the wireless power transmitter;
determining a charging voltage based on the received wireless charging power;
transmitting a signal, including voltage information corresponding to the determined charging voltage, to the wireless power transmitter;
if the determined charging voltage reaches a preset first voltage, determining a duration for which the determined charging voltage maintains the preset first voltage; and
changing a transmission cycle of the signal including the voltage information, if the duration exceeds a preset time.
