Description

[Technical Field] The disclosure relates to an electronic device having dual batteries and a method of controlling the same. [Background Art] Portable electronic devices, such as smartphones or tablets, may perform communication via various communication systems, such as cellular communication or short-range wireless communication, and may transmit and receive various information through various media according to the user's needs. However, when urgent communication is required in an emergency situation or in a situation or area where a communication system is unstable, communication through an existing communication system of an electronic device may be unstable or impossible, and thus a non-terrestrial wireless communication (e.g., satellite communication) service has been proposed. Electronic devices may transmit emergency SOS signals or help request messages via non-terrestrial wireless communication (e.g., satellite communication), and the transmitted messages may be relayed to ground-based rescue teams or relevant authorities. The above-described information may be provided as related art to aid understanding of the disclosure. No claim or determination is made as to whether any of the above is applicable as prior art related to the disclosure.
