Description

Method for adjusting transmission power according to whether a display is extended in an electronic device including a grip sensor The various embodiments disclosed in this document relate to an apparatus and method for controlling transmission power according to whether a display is expanded in an electronic device including a grip sensor. While portable electronic devices have historically shown a trend toward miniaturization to emphasize portability, recently, devices have emerged that are so large they render the term "portable" almost meaningless. Furthermore, recently released portable devices possess transformable characteristics, blurring the boundaries between classifications based on device size. Meanwhile, portable electronic devices include various sensors, including grip sensors. In particular, a grip sensor is a component that converts contact stimulation applied to a portable electronic device into an electrical signal and can perform the same function as a tactile nerve among the sensory nerves of the human body. In addition, portable electronic devices emit electromagnetic waves during use, and electronic devices released to the market are required to be designed so that the specific absorption rate (SAR), which defines the rate at which these electromagnetic waves are absorbed by the human body, is lower than a certain level.
