PURPOSE: To provide a battery remainder-displaying device for preventing the remainder of a battery from being judged to be an unduly small level immediately after changing from a call state to a wait state by using the sampling and averaging methods of a battery voltage in the case of level judgment when displaying the remainder of the battery with several levels. CONSTITUTION: A battery voltage measurement part 130 measures the battery voltage value of a battery 10 at each 0.5 seconds, and a correction part 140 adds a specified correction value based on a correction value table for a battery voltage value being measured in a call state. A level judgment part 120 obtains the average value of the current voltage value (a value after correction for those requiring correction) being measured for the last 15 seconds at each second, compares the average value with a level table being specified based on the characteristic of the current voltage value in the wait state, and judges the level and displays the display mark of the remainder of the battery for indicating the corresponding level on a LCD 110. |
