    Abstract: An apparatus and a method for are provided for a wireless power receiver. The method includes receiving power from a wireless power transmitter; measuring a temperature of a point in the wireless power receiver during reception of the wireless power; regulating the received power; identifying the temperature at a first time point; maintaining an amount of the regulated power to be provided to a battery with a first level if the identified temperature is lower than a preset temperature; decreasing the amount of the regulated power if the identified temperature is greater than or equal to the preset temperature; in response to decreasing the amount of the regulated power, identifying the temperature at a second time point after the first time point; and increasing the amount of the regulated power to the first level if the identified temperature at the second time point is lower than the preset temperature.
