Title:
PORTABLE TERMINAL
Document Type and Number:
Japanese Patent JP2019161931
Kind Code:
A
Abstract:
To provide a portable terminal capable of accurately displaying battery residue.SOLUTION: In a portable terminal, a battery internal resistance value is calculated from a measured voltage value and load current value of a battery before a predetermined time and a measured voltage value and load current value of a battery in this time (S18); the measured voltage value of a battery in this time is corrected based on the internal resistance value having been calculated (S20); and the residue of a battery is displayed on a display part 24, as an icon, based on a corrected voltage value of the battery (S22). A correction for a voltage drop of a battery voltage is performed, and the residue of a battery is displayed, so that, even when equipment has high load and power consumption is increased, battery residue is accurately displayed.SELECTED DRAWING: Figure 8
