Abstract: According to certain embodiments, an electronic device may include a temperature sensor sensing temperature information, a processor, and a touch circuit. The touch circuit may identify that the temperature information is lower than or equal to a designated threshold temperature, and may identify whether values included in pieces of touch sensing information are within a designated range. Each of the pieces of touch sensing information may include multiple values corresponding to multiple nodes of the touch circuit. On the basis of the result of identifying whether the values included in the touch sensing information are within the designated range, the touch circuit may not output touch information associated with at least one first node having a value within the designated range, to the processor. Alternatively, the touch circuit may output touch information associated with at least one second node having a value outside the designated range, to the processor.
