    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.

    Abstract: An apparatus and a method for are provided for a wireless power receiver. The method includes receiving power from a wireless power transmitter; converting the power in an alternating current (AC) form into a direct current (DC) form and providing the converted power to a battery of the electronic device; measuring a temperature of a point in the wireless power receiver during reception of the wireless power; maintaining an amount of the converted power at a first level if the temperature is lower than a preset temperature; decreasing the amount of the converted power to a second level which is lower than the first level if the amount of the converted power is at the first level and the temperature is higher than or equal to the preset temperature; increasing the amount of the converted power to the first level if the amount of the converted power is at the second level and the temperature is lower than the preset temperature; and transmitting, to the wireless power transmitter, a signal including status information of the wireless power receiver device and control information to control the wireless power transmitter.
