Electronic device for adjusting parameter for driving of grip sensor and method thereof

A method for controlling a grip sensor in an electronic device, the method comprising:

• detecting, in a first state for detecting a grip on the electronic device, the grip based on a capacitance adjusted by the grip and a reference capacitance;
• adjusting, in a second state, which is different from the first state, for adjusting the reference capacitance and is different from the first state, the reference capacitance based on the capacitance;
• and
• adjusting, based on identifying that the reference capacitance is adjusted to be greater than or equal to a preset threshold, the reference capacitance to be lower than the preset threshold.

An electronic device, comprising:

• a grip sensor which detects a grip on the electronic device;
• an antenna;
• and
• a communication circuitry which adjusts a strength of a wireless signal transmit by the antenna based on the grip detected by the grip sensor;
• wherein the grip sensor is configured to:
• detect the grip by comparing a capacitance changed by an external object different from the electronic device to a reference capacitance adjusted based on a preset period;
• adjust, while adjusting the reference capacitance based on the preset period, the reference capacitance based on the capacitance in a preset range associated with the reference capacitance.
