CHARGING METHOD FOR A BATTERY, AND AN ELECTRONIC DEVICE USING THE CHARGING METHOD

A method for charging a battery, and electronic device using the method, includes charging the battery with a first charge current Iat constant current in a mth charge-discharge cycle of the battery, wherein the battery has a first cut-off voltage Vwhen the constant current charging stage of the battery is cut off in the mth charge-discharge cycle. The first charge current Iis calculated according to a formula I=I+k×I, where, 0
