Various embodiments of the present disclosure relate to an electronic device that receives wireless power using a radio frequency (RF) signal, and a method for controlling the same.

Various services and additional functions provided through an electronic device, for example, a portable electronic device such as a smart phone, are gradually increasing. In order to increase the utility value of such electronic devices and satisfy the needs of various users, communication service providers or electronic device manufacturers are competitively developing electronic devices to provide various functions and differentiate them from other companies. Accordingly, various functions provided through the electronic device are also increasingly advanced.

Portable electronic devices such as mobile phones or personal digital assistants (PDAs) are driven by rechargeable batteries due to their characteristics, and in order to charge the batteries, electric energy is supplied to the batteries of the portable electronic devices by using a separate charging device. Typically, the charging device and the battery each have separate external contact terminals, so that the charging device and the battery can be electrically connected by contacting them with each other.

However, in such a contact charging method, since the contact terminals protrude to the outside, contamination by foreign substances is easy, and for this reason, a problem in that battery charging is not performed correctly may occur.
