A method of a charging battery includes the following steps: charging the battery with a first charging current in an nth charge and discharge cycle, where n is an integer greater than or equal to 0; and charging the battery with a second charging current in an (n+m)th charge and discharge cycle, where m is a preset integer greater than or equal to 1, Ib=k1×Ic, 0.5≤k1≤1, and Ic is a third charging current, where the third charging current is a smaller one of a first maximum charging current and a second maximum charging current in a same state of charge. This application further provides an electronic apparatus and a storage medium.
