An electronic device includes a display, a communication circuit, and at least one processor, and the at least one processor may be configured to establish a connection with a second external electronic device upon identifying that a packet is not received from a first external electronic device during set time while providing a location-based service for the first external electronic device, transmit, to the second external electronic device, a packet for requesting to operate as a relay device for obtaining a location of the first external electronic device, receive, from the second external electronic device, a packet including a distance and a direction between the second external electronic device and the first external electronic device, predict a location of the first external electronic device, and display, information indicating the predicted location of the first external electronic device.

Electronic device for providing location-based service and operating method thereof

Disclosed is an energy generating system having an integrated energy generator and energy storage. According to one embodiment, energy generation and storage may be performed using external kinetic energy, and output from a generator device may be improved using a voltage stored in the energy storage. A storage efficiency of the energy storage may be further increased via the improved output from the generator device. Further, the energy generator and energy storage may be integrated with each other to improve a space utilization.
