Abstract: Disclosed is an electronic device. The electronic device includes a battery, a charging part configured to be connectable to an external charging device to charge the battery, a memory, and a processor operatively connected to the charging part and the memory. The processor may determine whether the charging part is connected to the external charging device, determine whether the electronic device moves and/or electronic device usage time information of a user, and reduce a voltage at which the battery enters supplementary charging to a second voltage lower than a first voltage which corresponds to a value stored in the memory, based on whether the electronic device moves and/or the electronic device usage time information. In addition, it is possible to implement various other embodiments understood through the disclosure.
