A method is provided for folding an electronic device including a first housing and a second housing. The method includes an operation of calculating an angle between the first housing and the second housing. The operation of calculating the angle includes calculating, based on sensing data measured by a first sensor module disposed in the first housing and a second sensor module disposed in the second housing, an angle between the first housing and the second housing. The method further includes an operation of measuring a magnetic force value using a digital Hall sensor when a state of the foldable electronic device corresponding to the calculated angle corresponds to a set condition. The method further includes an operation of setting a first reference value associated with folding the foldable electronic device and a second reference value associated with unfolding the foldable electronic device based on the magnetic force value.
