1. An electronic device, comprising:
a first housing and a second housing;
a mechanical coupler by which the first housing and the second housing are movably coupled;
a first display and a first battery disposed in the first housing;
a second display and a second battery disposed in the second housing,
a first fuel gauge disposed in the first housing and sensing a state of the first battery;
a second fuel gauge disposed in the second housing and sensing a state of the second battery;
memory storing instructions; and
a processor, wherein the instructions, when executed by the processor, cause the electronic device to:
obtain the state of the first battery via the first fuel gauge,
obtain the state of the second battery via the second fuel gauge,
determine capacity ratios of the first and second batteries based at least on battery capacities of the first and second batteries, as identified via the first and second fuel gauges, respectively,
calculate a residual capacity of the first battery and a residual capacity of the second battery based on at least one of the determined capacity ratios and the obtained states of the first and second battery, respectively, and
output the calculated residual capacity of the first battery and the calculated residual capacity of the second battery via at least one of the first display or the second display.
