This application provides a battery charging method, an electronic apparatus, a storage medium, and a program product, and relates to the field of terminal technologies, to resolve a problem that some electrochemical cell is overcharged due to uneven voltage division of electrochemical cells in a charging process of a battery formed by a plurality of electrochemical cells connected in series. The method includes: obtaining a current charging current and voltages of n electrochemical cells; if a difference between a highest voltage in the voltages of the n electrochemical cells and a preset upper limit of a single electrochemical cell charging voltage is less than or equal to a preset difference, determining a derating current, where the preset difference is greater than or equal to 0, the highest voltage is less than or equal to the upper limit of the single electrochemical cell charging voltage, and the derating current is less than the current charging current; and indicating to charge the battery with the derating current.
