Title:
ELECTRONIC APPARATUS, BATTERY RESIDUAL QUANTITY CALCULATION METHOD, AND PROGRAM
Document Type and Number:
Japanese Patent JP2015102342
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an electronic apparatus, a battery residual quantity calculation method, and a program which can display a more accurate battery residual quantity while further reducing a processing load.SOLUTION: A CPU 101 measures use time of a battery 106. A voltage detection section 107 detects a voltage of the battery 106. The CPU 101 calculates a residual quantity of the battery 106 on the basis of the use time of the battery 106. When the voltage of the battery 106 is less than a predetermined threshold, the CPU 101 calculates the residual quantity of the battery 106 on the basis of the voltage of the battery 106. A display 105 displays the residual quantity of the battery 106, which is calculated by the CPU 101.
