1. A processor-implemented method with charging control, comprising:
estimating respective step degradation amounts in charging steps of a first charging interval for each of first candidate current patterns of charging a battery from a first state of charge (SOC) level to a second SOC level during the first charging interval;
determining an interval degradation amount in the first charging interval for each of the first candidate current patterns, based on the estimated step degradation amounts; and
selecting a first representative current pattern indicating a minimum degradation amount from among the first candidate current patterns, based on the determined interval degradation amounts.
