Abstract: The present invention provides a method and electronic device for controlling transmission power. An electronic device according to various embodiments comprises: a communication module; a memory; and a processor electrically connected to the communication module and the memory, wherein the processor may store a transmission power value during a first time when approaching to or gripping of the electronic device is detected, calculate an average transmission power value of transmission power values stored during the first time, control the communication module to transmit a signal at a first transmission power when an average specific absorption rate value corresponding to the calculated average transmission power value exceeds a threshold specific absorption rate value, and control the communication module to transmit the signal at a second transmission power which is different from the first transmission power when the average specific absorption rate value does not exceed the threshold specific absorption rate value. In addition, other embodiments are possible.

Abstract: A method for outputting audio data through an external device while preventing the generation of noise, and a portable terminal for the same are provided. The method for outputting audio data through the external device by the portable terminal includes identifying a connection voltage applied to a connection resistor included in the external device when a connection of the portable terminal to the external device is sensed, identifying a device code corresponding to the connection voltage, determining whether the external device is an audio output device according to the device code, and connecting a Universal Serial Bus (USB) interface, which is to be connected to the external device, to a ground (GND) for audio output if the external device is the audio output device.
