发明名称 Electronic apparatus and controlling method for the same
摘要 An electronic apparatus which is capable of correctly displaying the remaining usable time even if a discharged current of a battery pack is changed by an unexpected load due to an external apparatus connected. The electronic apparatus has a battery pack with a secondary battery mounted therein. A first remaining usable time of the electronic apparatus is calculated based on a consumed current of the electronic apparatus. A second remaining usable time of the electronic apparatus is calculated based on a discharged current of the secondary battery. The first remaining usable time calculated by the first remaining usable time calculating unit or the second remaining usable time calculated by the second remaining usable time calculating unit, whichever is smaller, is selected, and then a displaying unit displays the selected remaining usable time.
