Abstract: An electronic device is provided. The electronic device includes a housing, a battery disposed inside the housing, a power management module for controlling charging of the battery, and at least one processor operationally connected with the battery and the power management module. The at least one processor is provided to direct a plurality of charging intervals while charging the battery, each of the plurality of charging intervals having a target voltage, to alternately charge the battery in a first mode and in a second mode through the power management module, wherein a charging current flowing into the battery is uniformly maintained in the first mode and a voltage of the battery is uniformly maintained in the second mode, and to switch the first mode to the second mode when the voltage of the battery reaches the target voltage in the first mode.

Abstract: A method of controlling charging of a plurality of batteries and an electronic device to which the same is applied are provided. The electronic device includes a housing, a plurality of batteries arranged in the housing, a power management module that controls the plurality of batteries, a plurality of current limiting ICs that limits a maximum intensity of a current flowing into each of the plurality of batteries, and at least one processor operationally connected to the plurality of batteries, the power management module and the plurality of current limiting ICs. The at least one processor may set a total charging current output from the power management module, set an individual charging current flowing into each of the plurality of batteries in proportion to a total capacity of each of the plurality of batteries, and recalculate the individual charging currents when the total charging current changes.
