Abstract: A battery charging method and corresponding apparatus include charging a battery based on an initial charging operation, and verifying whether a change event, with respect to a charging operation, occurs based on the charging of the battery. The battery charging method and corresponding apparatus also include changing the charging operation to an adjusted charging operation in response to verifying that the change event, with respect to the charging operation, occurs. The change event includes a physical quantity event in which a physical quantity of the battery sensed during a charging rest time of the initial charging operation is greater than or equal to a threshold physical quantity.
