ELECTRONIC DEVICE AND METHOD FOR CHARGING BATTERY

A method for charging a battery includes charging the battery with a charging current at a constant current during an mth charge and discharge cycle; a first state of charge SOCof the battery when the constant current charging phase in any one charge and discharge cycle ends is the same as a standard state of charge SOC, SOC≤SOC≤SOC+k. SOCis a state of charge or a preset value of the battery at the end of the constant current charging phase during an nth charge and discharge cycle, SOCis a state of charge or a preset value of the battery at the end of the constant current charging phase during an (m−1)th charge and discharge cycle, SOC≤SOC≤SOC+k, 0≤k≤10%, and SOC+k≤100%.
