1. An electronic device comprising:
a housing;
a plurality of batteries arranged in the housing;
a power management circuit configured to control the plurality of batteries;
a plurality of current limiting integrated circuits (ICs) configured to limit a maximum intensity of a current flowing into the plurality of batteries, respectively; and
at least one processor operationally connected to the plurality of batteries, the power management circuit, and the plurality of current limiting ICs,
wherein the at least one processor is configured to:
set a total charging current output from the power management circuit,
set individual charging currents flowing into each of the plurality of batteries, respectively, in proportion to a total capacity of each of the plurality of batteries regardless of current remaining capacities of the plurality of batteries,
after setting both the total charging current output from the power management circuit and the individual charging currents flowing into each of the plurality of batteries, determine whether the total charging current set has changed, and
based on determining that the total charging current changed after being set, recalculate the individual charging currents.
