0), the state of the mobile phone is output to the use time calculation unit 10 (202), the standby time and the talk time are input from the use time calculation unit 10 (204), and it is determined whether the state of the mobile phone is in standby. If the display mode is standby (Yes), it is determined whether the display mode is standby (20).
8) If the display mode is the standby mode (Yes), the standby time is displayed on the display unit 5 (210), and the available time display process ends.

On the other hand, in the process 206, if the state of the portable telephone is busy (No), the available time (actually the minimum available time) is displayed on the display unit 5 (212),
The usable time display processing ends.

In step 208, if the display mode is set to talk (No), the process proceeds to step 212 to display the talkable time.

In the above description, the available time display processing of the control unit 2 is activated every time a predetermined time is counted by a timer circuit built in the control unit 2 so that the standby time and the call enable time are displayed. The time is updated, and the extent of the fixed time is set in consideration of the accuracy of the usable time to be displayed.

However, as another method for reducing the load of the processing related to the display of the available time, the control unit 2 activates the display processing of the available time at the start and end of the call, and sets the standby time and the call. The possible time may be updated, and during that time, the standby possible time and the talkable time displayed on the display unit 5 may be decremented. In order to reduce the load to some extent and to increase the accuracy of the usable time, the certain time is set longer, and during that time, the display unit 5
