DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a block diagram of an embodiment of a main part of a portable communication device according to the present invention. This embodiment is an example applied to a mobile phone. As setting items for various functions, ring volume setting 1, ring tone setting 2, mail ringing time setting 3, LCD backlight illumination brightness setting 4,
Key backlight illumination brightness setting 5 and the like. In these setting items 1 to 5, the current level values 6 (I1) to 10 (I5) of the consumed current change depending on the setting values.

Each of the above current level values I1 to I5 is
As shown in Table 1, when it is 0 to 10 mA, "level 1",
"Level 2" at 10 to 20 mA, "Level 3" at 20 to 30 mA, "Level 4" at 30 to 40 mA,
It is selected and determined from these levels as "level 5" at 40 to 50 mA and "level 6" at 50 to 60 mA.

[0017]

[Table 1] The current level values of all the selected functions are added up by the total current level determination unit 11 and then compared with the threshold value. The comparison determination result is supplied to the display unit 12 and displayed as a standard of current consumption.

Next, the operation of the present embodiment will be described with reference to FIG.
Will be described with reference to. 2, the same components as those in FIG. 1 are designated by the same reference numerals. In FIG. 2, the operation of the incoming call volume setting 1 shown by the broken line A in FIG. 1 will be described as an example. The ring volume setting 1 can be set in 6 levels from ring volume setting = 1 (101) to ring volume setting = 6 (106), and the ring volume changes according to the set value.
Here, it is assumed that the volume of incoming volume setting = 1 (101) is the smallest, the volume gradually increases as the volume setting value increases, and the volume becomes maximum when the incoming volume setting = 6 (106).

Further, the level value I1 of the current consumed when the ring tone volume setting = 1 is set to level 1 (61), and similarly, the ring tone volume setting = 2, 3, 4, 5 and 6 are consumed respectively. The current level value I1 of the current is level 2 (6
2), Level 3 (63), Level 4 (64), Level 5
(65) and level 6 (66). Current level value 6
Levels 1 to 61 have the smallest values, levels 1 to 61 have the largest levels, and level 6 (66) has the largest values. These ring tone volume settings and current level values I1
The relationship between and is previously measured and stored in the memory.

Now, ring volume setting 1 = ring volume setting = 5
If (105) is set, the value of level 5 (65) which is the current level value I1 at that time is input to the total current level determination unit 11. On the other hand, as functions other than the ring tone volume setting 1, there are ring tone setting 2, mail calling time setting 3, LCD backlight illumination brightness setting 4, key backlight illumination brightness setting 5 and other functions shown in FIG. Then, ring tone setting 2, mail ringing time setting 3
And the LCD backlight illumination brightness setting 4 are set respectively.

Here, the current level value I2 according to the setting item of the ring tone setting 2 is level X, the current level value I3 according to the setting item of the mail calling time setting 3 is level Y, and the LCD backlight illumination brightness. If the current level value I4 corresponding to the setting item of setting 4 is level Z,
The current values at these levels are also input to the total current level determination unit 11. In the ring tone setting 2 described above, the average current consumption per unit time is measured for each of the plurality of ring tone types, and this is set as the current consumption level value of the selected ring tone type.

In the total current level determination section 11, the level 5 (65) of the current level value I1 of the ring tone volume setting = 5 is set.
And the current level values of the ring tone setting level X, the mail reading time setting level Y, and the LCD backlight illumination brightness setting level Z (step 1).
11), the total value G thereof is compared with threshold values M and N (however,
M> N) is compared (step 112), and the comparison result is output to the display unit 12.

Here, according to the above comparison of magnitudes, the total current level determination unit 11 determines that the level A is greater than the first threshold M, which is the larger summed value G (G ≧ M).
Is output, and the sum value G is less than the first threshold value M and is less than or equal to the smaller second threshold value N (M> G ≧).
When the intermediate level is N), the comparison result of the level B is output, and when the combined value G is a small level less than the second threshold value N (N> G), the comparison result of the level C is output.

The display unit 12 includes a total current level determination unit 11
When the comparison result from 1 is level A, it is displayed on the display portion 121, when it is level B, it is displayed on the display portion 122, and when it is level C, it is displayed on the display portion 123. The level display on the display unit 12 allows the user of the mobile phone to know the standard of the current consumption amount corresponding to the setting item set by the user.

The display unit 12 may be provided with a display unit dedicated to the current consumption display, or may be constantly displayed in a partial area of the LCD screen for performing various displays. FIG. 3 shows a display example when the current consumption is displayed on the dedicated display unit 12. In FIG. 3, the level A is displayed as “large”, the level B is displayed as “medium”, and the level C is displayed as “small”, but here it is displayed as “medium”.

According to the present embodiment, when the level A is displayed, it can be seen that the current consumption is large. Therefore, if the user feels that the usage time is short, the current consumption should be further reduced. You can change the function settings to suit your needs. Also, when the level C is displayed, it can be seen that the current consumption is small, so it is necessary to add the setting of other functions or change the setting items with large current values even for the functions that have already been set. Is also possible.

Further, in the present embodiment, when the ringtone is made louder or the backlight illumination is made brighter, the amount of current consumption increases, and as a result, the battery consumption is faster.
Only a limited number of people are aware of this, but it can be widely known. In addition, in the present embodiment, the conventionally known battery remaining amount display is also performed, and the reason why the battery consumption is fast can be inferred from the above current consumption display.

It should be noted that the total current level determination unit 11 is shown in FIG.
Of course, when other functions other than the above are set, the current level value corresponding to the setting item is input and the summing operation is performed.

The present invention is not limited to the above embodiment, and the relationship between the current value and the level value is not limited to Table 1, for example. Further, the total current level determination unit 11 has two threshold values M and N to be compared with the summed value G, but the present invention is not limited to this, and three or more threshold values may be provided. . When three or more threshold values are set, the current consumption can be displayed more finely, and for example, a bar graph display as shown in FIGS. 4 and 5 is also possible. FIG. 4 is an example in which an intermediate level between “small”, “medium”, and “large” is also displayed, and FIG. 5 is an example in which six levels of current consumption are set. Furthermore, the present invention can be applied to other portable communication devices using a battery (battery) as an operating power source, other than the mobile phone. Further, the present invention is also applicable to a mobile communication terminal having a function capable of setting only one item among a plurality of functions.

[0030]

As described above, according to the present invention,
The same function is displayed by displaying the comparison judgment result obtained by comparing the sum of the current level values of the current consumption corresponding to the set item among the multiple functions with multiple different thresholds. Since it is possible to display the approximate value of current consumption that changes depending on the set item even if it is set,
You can make optimal settings for various function settings according to the battery level.

Further, according to the present invention, instead of simply displaying the total value of the consumption current, by displaying the comparison / judgment result obtained by comparing the plurality of threshold values different from each other, Since an easy-to-understand display can be made, it is possible to quickly determine the amount of current consumption.

Further, according to the present invention, only a limited number of people recognize that the amount of current consumption increases when the ring tone is made louder or the backlight illumination is made brighter, and as a result, the battery drains faster. It is possible to widely notify general users of the absence.
