1. A terminal, comprising:
a battery; and
an integrated circuit (IC) configured to:
charge the battery with a charging current being variant in a step charging mode by changing a level of the charging current stepwise when a voltage of the battery reaches a first threshold voltage and is less than a second threshold voltage,
the first threshold voltage set to maintain an anode potential of the battery to be greater than or equal to a reference value during the charging of the battery; and
change the step charging mode to a constant voltage charging mode in response to the voltage of the battery reaching a third threshold voltage.
