Device and method for controlling transmission power according to whether display is extended in electronic device comprising grip sensor

Abstract

An electronic device according to various embodiments comprises: a slidable housing including a first housing and a second housing; a flexible display visible to the outside of the electronic device via at least a part of the slidable housing; a wireless communication circuit; a grip sensor; and at least one processor electrically connected to the flexible display, the wireless communication circuit, and the grip sensor, wherein the at least one processor is configured to: recognize that the slidable housing is in a first state and sets, to a first parameter corresponding to the first state, a parameter related to the proximity of a human body if a capacitance measurement value associated with the slidable housing satisfies a first range, and recognizes that the slidable housing is in a second state different from the first state and sets the parameter to a second parameter corresponding to the second state if the capacitance measurement value associated with the slidable housing satisfies a second range different from the first range, and the wireless communication circuit can control transmission power based on the result of comparison between a value measured by the grip sensor and the first parameter or the second parameter.
