According to various embodiments, an electronic device comprises a communication processor, an application processor operatively connected to the communication processor, and a memory, wherein the at least one memory may store instructions configured to, when executed, cause the application processor to identify a user identifier (UID) corresponding to at least one allowed application or at least one disallowed application when the electronic device enters a power saving state and to generate, on the basis of the user identifier, a first packet filter program which includes at least one condition for filtering a packet, and cause the communication processor to identify the first packet filter program generated from the application processor and to filter at least one packet associated with an application other than the at least one allowed application or at least one packet associated with the at least one disallowed application by using the first packet filter program, while the electronic device is in the power saving state. Various other embodiments are possible.
