Electronic device for reducing power consumption and operating method thereof

An electronic device comprising:

• a display;
• a wireless communication circuitry capable of supporting a plurality of communication networks;
• a processor operatively connected with the display and the wireless communication circuitry;
• and
• a memory operatively connected to the processor,
• wherein the memory stores instructions that, when executed by the processor, cause the electronic device to:
• establish a connection with a first cellular communication network among the plurality of communication networks, based on control information received from a second cellular communication network among the plurality of communication networks,
• perform first data communication with the first cellular communication network via the established connection with the first cellular communication network, and
• based on a determination that the display has been in an inactive state for a reference time period and that a data throughput detected in a state of the connection with the first cellular communication network has been established is lower than a reference throughput:
• establish a connection with the second cellular communication network, and perform second data communication with the second cellular communication network via the established connection with the second cellular communication network, and
• release the connection with the first cellular communication network.
