Abstract
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<k≤1, Iis the charging current of the constant current charging stage of the battery or another battery identical to the battery in the nth charge-discharge cycle, or Ican be a preset value, n is an integer and is greater than or equal to 0, and m is an integer greater than n, the value of k is not the same in at least two charge-discharge cycles of the battery.
