Abstract
The present invention provides a charge management method for a battery in a mobile terminal having the steps of: setting an initial charge start point; setting a statistic analysis interval for gathering the remaining capacity of the battery at time of start and creating a statistic array for recording the remaining capacity of the battery upon each power-on operation in the statistic analysis interval; reading current remaining capacity of the battery and storing it sequentially in the statistic array; calculating a new charge start point based on a predetermined adaptive algorithm; and updating the initial charge start point with the new charge start point. The present invention also provides a charge management apparatus for a battery in a mobile terminal. With the present invention, it is possible to set an optimal charge start point through measurements, and thus lengthen the battery's lifetime. Especially for users who rarely use a battery to supply power, the battery's lifetime can be considerably extended in a smart way, and the safety of use of battery is improved.
