Electronic device including sensor and method for operating the same

A method for operating an electronic device, the method comprising:

• controlling a switch included in the electronic device to connect a first capacitor included in the electronic device and a sensor included in the electronic device, based on start of booting of the electronic device;
• determining an initial value of the sensor for determining whether a user grips at least a portion of the electronic device, based on connection of the first capacitor and the sensor;
• and
• controlling the switch to connect an antenna circuit included in the electronic device and the sensor, based on the determination of the initial value of the sensor.

An electronic device comprising:

• an antenna circuit including an antenna;
• a first capacitor;
• a sensor;
• and
• at least one processor,
• wherein the at least one processor is configured to:
• connect the first capacitor and the sensor using a first channel connected to the sensor, based on start of booting of the electronic device,
• determine an initial value of the sensor for determining whether a user grips at least a portion of the electronic device, based on connection of the first capacitor and the sensor, and
• connect the antenna circuit and the sensor using a second channel connected to the sensor, based on the determination of the initial value of the sensor.
