acquiring at a preset time interval current time and historical power supply data corresponding to the current time when a preset condition for switching a charge mode of a battery is met, wherein the historical power supply data comprises actual power supply information of a terminal loaded with the battery within a time period determined according to a battery endurance time of the terminal and the current time;

determining a corresponding predicted charge mode according to the historical power supply data, wherein the predicted charge mode comprises a first charge model and a second charge model; a fully-charged capacity of the first charge model is smaller than a fully-charged capacity of the second charge model, and a recharged capacity of the first charge model is smaller than a recharged capacity of the second charge model; and

updating a current charge mode of the terminal according to the predicted charge mode,

wherein after the current time and the historical power supply data are acquired, and before the corresponding predicted charge mode is determined according to the historical power supply data, the method for battery charge management further comprises:

judging whether a data amount of the historical power supply data is greater than or equal to a preset data amount threshold; and

determining the corresponding predicted charge mode according to the historical power supply data when the data amount of the historical power supply data is greater than or equal to the preset data amount threshold.
