The present application relates to a flexible electronic device for sensing a deformation state and a method for operating the same. An electronic device comprises a housing; a flexible display; at least one first sensor disposed in the housing; at least one second sensor disposed in the housing and different from the at least one first sensor; at least one processor disposed in the housing and operatively connected to the flexible display, the at least one first sensor, and the at least one second sensor; and memory operatively connected to the at least one processor, wherein the memory stores instructions that, when executed, cause the at least one processor to perform a plurality of operations comprising: acquiring first data from the at least one first sensor; activating the at least one second sensor at least partially based on the acquired first data; acquiring second data from the at least one second sensor; and sensing a deformation state of the flexible display at least partially based on the acquired first or second data.
