1. A method for controlling temperature of a battery installed in an electronic device by utilizing waste heat generated by a heat source therein, wherein said heat source comprises a display apparatus that generates thermal energy when operating, comprising the steps of:

  • transferring said waste heat to said battery by thermal conduction, thereby bringing the temperature of said battery to a value at which the performance of said battery is enhanced;

    varying thermal resistance relating to said conduction heat transfer to bring said temperature value to within a desired temperature range in which the performance of the battery is enhanced; and

    transferring said waste heat away by convection to lower the temperature of said heat source to within a desired temperature range, wherein said convection heat transfer is brought about by a fan.
