Description

  The present invention relates to a software determination device, a terminal device, a software determination method, a software determination program, and a communication system.

A mobile phone device, which is a type of mobile terminal device, has various functions such as mail transmission / reception, web browsing, camera, and game in addition to a call function.
The mobile phone device is equipped with a battery (secondary battery) due to its characteristics, and is driven by electric power charged in the battery when carried by a user. For this reason, in the mobile phone device, it is necessary to ensure the duration of the charged battery.

In a conventional mobile phone device, only one application (hereinafter also referred to as an application) can be activated at the same time, so the operation of a CPU (Central Processing Unit) and memory is necessarily limited to one application. .
However, in recent mobile phone devices called smartphones, platforms based on technology cultivated in personal computers (personal computers) are employed. And in such a mobile phone device, like a personal computer, it becomes possible to start a CPU and a memory by a plurality of multitasks, and to execute a plurality of applications simultaneously in the foreground and background, and relatively power consumption is reduced. Consumption tends to increase. For this reason, in such a mobile phone device, there is a problem that the duration of the battery becomes shorter and shorter than the conventional mobile phone device.

By the way, an application that operates on a smartphone may operate in a place not intended by the user regardless of whether the user has activated the application.
For example, in the case of a social application, location information, a phone book, a profile, a running application or task, the contents of a calendar, and the like are collected in the background, and the collected information is periodically transmitted to the server device. Thus, the collected information can be used on the server device side for user hobbies or preference analysis, social graph analysis, search, and search for friends who are geographically close.
In the case of a news-type or game-type application, in order to keep the information presented to the user always up-to-date, a request for acquiring information may be periodically transmitted to the server device in the background. In the case of a backup-type application, similarly, data to be backed up is periodically transmitted to the server device.
Furthermore, in the case of an app that accepts push notifications from the server device, TCP (Transmission Control Protocol) / UDP between the server device and the app so that the server device can send a notification signal to the app at any timing. Since it is necessary to maintain a (User Datagram Protocol) connection, a keep alive packet may be periodically transmitted to the server apparatus.

  As described above, there are apps for various purposes, and there are also a variety of apps that run in the background, and users generally recognize that these apps are running in the background. Absent. As the number of apps that operate in the background increases, the operating rate of the CPU and memory increases, which causes a problem that the duration of the battery is shortened against user recognition.

As a specific example, when the mobile terminal device 1 holds a file in which the accumulated value of the CPU usage time from when the mobile terminal device 1 is activated until the current time is recorded, the file is recorded in the previous file. By calculating the difference between the accumulated value and the accumulated value recorded in the current file, the CPU usage time can be detected (determined) within the time range of the information collection cycle. In addition, when the mobile terminal device 1 holds a file in which the communication amount for each of the software 101-1 to 101-N is recorded, if the information collection time interval is X (X is greater than 0) seconds, When there is a difference in the communication amount between the time before X seconds and the current time, it is considered that the communication has been performed for X seconds, and the usage time of the communication circuit can be detected (determined) as X seconds.

  The information collected by the software use resource collection unit 21 may be recorded in the storage device in association with, for example, date and time. This information may be recorded, for example, as a file in an internal storage device or an external storage device. This information may be recorded in a storage device of an external device such as a server device.

(Step S2)
The software consumption current acquisition unit 22 uses the software 101-1 to 101-N based on information about the usage status of the resources 12 used by the software 101-1 to 101-N (information collected by the software use resource collection unit 21). The current consumption of 101-N is calculated, and the information of the current consumption of each software 101-1 to 101-N is acquired.

May be.
As the timing for calculating the consumption current, for example, the timing of a predetermined time of the day, the timing of a predetermined time period, the timing of execution instructed directly by the user, or the timing satisfying a predetermined condition, Any one or more of these may be used. The conditions at the timing satisfying the predetermined condition include, for example, a condition that the mobile terminal device 1 is in a charged state, a condition that the remaining amount of the battery 13 is greater than or equal to a predetermined value, and a running software that is predetermined. Any one or more of a condition that the CPU load is less than a predetermined value or a condition that the CPU load is less than or equal to a predetermined value may be used.
The time period (period) for which the current consumption is calculated is, for example, one of a predetermined number of days, a predetermined time, a predetermined condition, or a combination of these. May be used. As predetermined conditions, for example, the condition that the mobile terminal device 1 is being charged, the condition that the mobile terminal device 1 is being discharged, and the remaining amount of the battery 13 are greater than or equal to a predetermined value. Or a condition that the remaining amount of the battery 13 is a predetermined value or less may be used.

In addition, the software consumption current acquisition unit 22 may acquire, for example, information on consumption current when each of the software 101-1 to 101-N is in a predetermined state. As the predetermined state, for example, a state where each software 101-1 to 101-N is in the background may be used. In addition, when both the state where each software 101-1 to 101-N is in the background and the state where they are in the foreground exist in the time interval for acquiring the current consumption information, the time in the background state is predetermined. The current consumption may be calculated when the threshold is exceeded, and the current consumption may be regarded as zero (0) when the time in the background is equal to or less than a predetermined threshold. Further, the current consumption may be calculated when the time in the foreground state is below a predetermined threshold, and the current consumption may be regarded as zero (0) when the time in the foreground state is equal to or greater than the predetermined threshold.
The software consumption current acquisition unit 22 may refer to the history information (log) of the usage status of each software 101-1 to 101 -N.

In the present embodiment, the terminal consumption current acquisition unit 23 acquires information in the same interval as the time interval in which the software consumption current acquisition unit 22 acquires information.
Note that the timing at which the terminal consumption current acquisition unit 23 acquires the information on the entire consumption current of the mobile terminal device 1 may be another timing, for example, the process in which the software consumption current acquisition unit 22 acquires information. The timing at which (for example, calculation) is completed (for example, the timing immediately after being completed) may be used, or the timing independent of the process in which the software consumption current acquisition unit 22 acquires information is used. Also good. In addition, information on the current consumption of the entire mobile terminal device 1 acquired by the terminal current consumption acquisition unit 23 is stored in the storage device of the mobile terminal device 1 or an external storage device by the terminal current consumption acquisition unit 23.

As a specific example based on the information of the battery 13, a method of calculating the total current consumption based on the decrease value of the remaining amount of the battery 13 in a predetermined time and the capacity of the battery 13 of the mobile terminal device 1 may be used. Good. For example, when the decrease value of the remaining amount of the battery 13 per 2 hours is 1 percent (%) and the capacity of the battery 13 is 2000 mAh, the total current consumption of the mobile terminal device 1 is 10 mA (= 2000 mAh). ÷ 100% ÷ 2h) (where h represents time).
As a specific example based on the overall usage status of the resource 12, the total current consumption of each resource 12 obtained by integrating the usage time of each resource 12 and the coefficient of current consumption is the total of the mobile terminal device 1. A method that considers current consumption may be used.
In the present embodiment, information on the current consumption of the mobile terminal device 1 (or what is regarded as the whole) is used. However, as another configuration example, information on current consumption as another reference is used. Also good.

(Step S4)
The battery influence degree acquisition unit 24 analyzes the degree of influence of the software 101-1 to 101-N on the battery 13 based on the result of the process of step S2 and the result of the process of step S3, and acquires the information.

In the present embodiment, the battery influence degree acquisition unit 24 is a battery by each of the software 101-1 to 101-N in the same period as the time period during which the software consumption current acquisition unit 22 and the terminal consumption current acquisition unit 23 acquire information. 13 is analyzed.
The timing at which the degree of influence on the battery 13 by each of the software 101-1 to 101-N is analyzed by the battery influence degree acquisition unit 24 may be other timing. For example, the terminal consumption current acquisition unit 23 may The timing at which the information acquisition (for example, calculation) ends (for example, the timing immediately after the completion) may be used, or the software consumption current acquisition unit 22 and the terminal consumption current acquisition unit 23 acquire information. A timing independent of the processing to be performed may be used. In addition, information regarding the result of the analysis performed by the battery influence degree acquisition unit 24 may be stored in the storage device of the mobile terminal device 1 or an external storage device by the battery influence degree acquisition unit 24.

  In the present embodiment, the battery influence degree acquisition unit 24 calculates an index indicating the influence degree of the battery 13, and evaluates the magnitude relationship between the calculated index and a predetermined threshold value. As an example, the battery influence level acquisition unit 24 reaches a predetermined remaining amount (second remaining amount different from the first remaining amount) from a predetermined remaining amount (first remaining amount) of the battery 13. The arrival time is calculated in a state in which each software 101-1 to 101-N is operable and in an inoperable state, and the difference (change amount) between these two arrival times is calculated as an index. As another example, the battery influence degree acquisition unit 24 relates to the battery 13 so that the total amount of consumed current (discharge amount) is changed from a predetermined discharge amount (first discharge amount) to a predetermined discharge amount (first discharge amount and the first discharge amount). Is calculated for a state where each software 101-1 to 101-N is enabled and disabled, and the difference between these two arrival times ( Change amount) as an index. The battery influence level acquisition unit 24 determines that the influence on the battery 13 is large when it is determined that the calculated index is equal to or greater than the predetermined threshold, while the calculated index is less than the predetermined threshold. If it is determined that the influence on the battery 13 is small. The battery influence degree acquisition unit 24 acquires the determination result as an analysis result.

  Here, in the mobile terminal device 1, the software 101-1 to 101-N can be operated, for example, when the software 101-1 to 101-N is installed in the mobile terminal device 1, This represents a state in which each software 101-1 to 101-N can operate. On the other hand, the state in which the software 101-1 to 101-N is made inoperable is, for example, that each software 101-1 to 101-N is uninstalled from the mobile terminal device 1, or each software 101- 1 to 101-N is not uninstalled but is invalidated, which indicates that the operation of each of the software 101-1 to 101-N is impossible. Further, for example, in a state where the processing by each software 101-1 to 101-N is being executed, the operation of each software 101-1 to 101-N is impossible due to the forced termination of the processing. The state in the case of becoming may be included.

As a specific example, a method of directly calculating based on the remaining amount of the battery 13, a method of calculating based on the consumed current calculated based on the remaining amount of the battery 13 in the process of step S3, or a resource in the process of step S3 Any of the methods of calculating based on the sum of the 12 current consumptions may be used. In the method of directly calculating based on the remaining amount of the battery 13, the battery influence degree acquisition unit 24 collects information on changes in the remaining amount of the battery 13, for example.
On the other hand, as a method of calculating the arrival time relating to the remaining amount or discharge amount of the battery 13 in a state where each of the software 101-1 to 101-N is inoperable, for example, the result of the process in step S2 and the process in step S3 A method using the processing result may be used. As a specific example, the current consumption obtained by subtracting the current consumption of each software 101-1 to 101-N (the result of the process in step S2) from the overall current consumption of the mobile terminal device 1 (the result of the process in step S3). A method of calculating the arrival time based on the above may be used. Alternatively, a method may be used in which the arrival time is calculated based on the current consumption as a result of subtracting the resource use time of each software 101-1 to 101-N.

  As another configuration example, as an index, the ratio of the current consumption of each software 101-1 to 101-N (the result of the process of step S2) to the overall current consumption of the mobile terminal device 1 (the result of the process of step S3). May be used. In this case, when it is determined that the ratio (index) is equal to or greater than the predetermined threshold, it is determined that the influence on the battery 13 is large. On the other hand, when it is determined that the ratio (index) is less than the predetermined threshold. Determines that the influence on the battery 13 is small.

As a method for determining the degree of influence on the battery 13, a method other than the method for evaluating the magnitude relationship between the remaining amount of the battery 13 or the amount of change in the discharge amount and the threshold value may be used. As an example, based on current consumption information reduced by changing each software 101-1 to 101-N from an operable state to an inoperable state and software current consumption information frequently used by users, The number of times of use (or use time) of the software frequently used by the user, which can be increased when each software 101-1 to 101-N is changed from an operable state to an inoperable state, is calculated, and the result of the calculation Is determined to be greater than or equal to a predetermined threshold, it is determined that the influence on the battery 13 is large. On the other hand, if it is determined that the result of the calculation is less than the predetermined threshold, it is determined that the influence on the battery 13 is small. May be. As software often used by the user, for example, software that may be set by the user, or software whose usage frequency is higher to a predetermined number based on the usage frequency of each of the software 101-1 to 101 -N is used. May be.
As another example, each software 101-1 to 101-101 regarding the maximum use frequency (or maximum use time) of software frequently used by the user, which is possible until the remaining amount or discharge amount of the battery 13 reaches a predetermined value. When it is determined that the number of times (or time) that can be increased when N is changed from an operable state to an inoperable state is greater than or equal to a predetermined threshold, it is determined that the influence on the battery 13 is large, When it is determined that the number of times (or time) is less than the predetermined threshold, it is determined that the influence on the battery 13 is small.

(Step S5)

Independently, information on the usage status of each of the software 101-1 to 101-N may be acquired. The information regarding the usage status of each software 101-1 to 101-N by the user includes, for example, information indicating whether or not the user has used each software 101-1 to 101-N.

As a situation in which the user uses each software 101-1 to 101-N, for example, each software 101-1 to 101-N is activated in a state having a user interface that can be operated by the user. A situation (for example, a foreground situation) in which 1-101-N transitions to the forefront of the display unit of the mobile terminal device 1 may be used. Or the situation where the user touched the screen of the display part and operated each software 101-1 to 101-N may be used. Alternatively, the software (software 101-1 to 101-N) specialized only for the user interface that can be operated by the user is activated, and a situation in which a part of the software resides in the forefront of the mobile terminal device 1 is used. May be. Alternatively, a situation in which the user operates a part of software (software 101-1 to 101-N) by touching the screen of the display unit may be used. Or two or more of these situations may be used.
On the other hand, as a situation in which the user does not use each of the software 101-1 to 101-N, for example, the software (software 101-1 to 101-N) is activated with a user interface that can be operated by the user. Regardless, a situation in which the software (software 101-1 to 101-N) exists in a location other than the forefront of the mobile terminal device 1 may be used. Alternatively, a situation (for example, a background situation) in which software (software 101-1 to 101-N) is activated without a user interface that can be operated by the user may be used. Or these two situations may be used.
Normally, when a user specifies a situation where each software 101-1 to 101-N is used, the other situation is a situation where the user does not use each software 101-1 to 101-N. Can be considered. Similarly, when the situation where the user is not using the software 101-1 to 101-N is normally specified, the other situation is a situation where the user uses the software 101-1 to 101-N. Can be considered.

  As a section (period) of time for acquiring information on the usage status of each software 101-1 to 101-N by the user, for example, a section of a predetermined number of days, a section of a predetermined time, a section satisfying a predetermined condition, or Any one of these combinations may be used. As predetermined conditions, for example, the condition that the mobile terminal device 1 is being charged, the condition that the mobile terminal device 1 is being discharged, and the remaining amount of the battery 13 are greater than or equal to a predetermined value. Or a condition that the remaining amount of the battery 13 is a predetermined value or less may be used.

(Step S6)
The user-presented software determination unit 26 analyzes the influence of the software 101-1 to 101-N on the battery 13 performed by the battery influence degree acquisition unit 24 and the software performed by the user performed by the usage degree acquisition unit 25. Based on the analysis result of the degree of use of 101-1 to 101-N, software to be presented to the user (for example, one or more of the software 101-1 to 101-N) is determined. As a result, the user-presented software determination unit 26 presents to the user information related to software that has a large influence on the battery 13 and has a low degree of use (for example, the corresponding one of the software 101-1 to 101-N). To help you.
Information related to the software determined by the user-presented software determining unit 26 may be stored in the storage device of the mobile terminal device 1 or an external storage device by the user-presented software determining unit 26.

In the present embodiment, the user presented software determination unit 26 first selects software (for example, one or more of the software 101-1 to 101-N) determined to have a large influence on the battery 13. Next, the user-presented software determination unit 26 determines (evaluates) whether or not the usage status of the software satisfies a predetermined condition for the selected software, and presents the software determined to satisfy the predetermined condition Determine as the software.
As another configuration example, the user-presented software determination unit 26 first selects software that is determined to have a usage condition that satisfies a predetermined condition, and then determines that the selected software has a large influence on the battery 13. If it is, the software may be determined as the software to be presented.

Here, as the predetermined condition regarding the usage status of the software, for example, a condition that a certain condition is satisfied in a situation where the software is used, or a certain condition is satisfied in a situation where the software is not used. Any of the conditions may be used.
In the situation where software is used, for example, in the section of a predetermined number of days, the section of a predetermined time, the section of a time satisfying a predetermined condition (period), or a combination of these sections The condition that the situation using the software is less than or equal to a predetermined number of times, a predetermined time, or a predetermined ratio may be used.
On the other hand, the above-mentioned certain conditions in the situation where software is not used include, for example, a predetermined number of days, a predetermined time, a time period (period) satisfying a predetermined condition, or a combination thereof. A condition may be used in which the situation in which the software is not used in the section is equal to or greater than a predetermined number of times, a predetermined time, or a predetermined ratio.
Note that the time interval that satisfies the predetermined condition includes, for example, a condition that the mobile terminal device 1 is charged, a condition that the mobile terminal device 1 is discharged, and the remaining amount of the battery 13. Either a condition that is equal to or greater than a predetermined value or a condition that the remaining amount of the battery 13 is equal to or less than a predetermined value may be used.

The user presented software determination unit 26 presents information regarding software determined as the software to be presented to the user. This presentation is performed, for example, by displaying information on the screen of the display unit or by outputting information (voice) from a speaker.
At this time, the user presenting software determination unit 26 may present, for example, information regarding the analysis result acquired in the process of step S4. As a specific example, the amount of change in the time to reach a predetermined remaining amount or a predetermined discharge amount of the battery 13, or the number of times of increase in the use of a predetermined software (or use increase time, maximum use count, or maximum use time) Information about may be presented.

  The number of pieces of software to be presented to the user may be any number greater than or equal to 1, for example, a number equal to or less than a predetermined number, a number satisfying a predetermined condition, or a combination thereof Numbers may be used. As the predetermined condition, for example, a condition in which software installed in the mobile terminal device 1 in a factory shipment state is excluded from the presentation target, or a file in which a list of software excluded from the presentation target is described is read. Thus, any one or more of the conditions for excluding the software described in the file from being presented may be used.

  In addition, for example, when the total current consumption in the mobile terminal device 1 exceeds a predetermined value, two or more pieces of software (two or more pieces of software determined by the user presented software determination unit 26) can be operated. Information such as an effect obtained by summing up the effects of the inoperable state may be presented. In this configuration, for example, when the overall current consumption in the mobile terminal device 1 is large, the effect of disabling the individual software 101-1 to 101-N may appear to be small. The total effect value obtained by disabling the plurality of software 101-1 to 101-N can be displayed, and the effect of appearance can be shown greatly.

FIG. 3 is a diagram illustrating a specific example of processing performed in the mobile terminal device 1 according to an embodiment of the present invention.
FIG. 3 shows the behavior of screen transition for a certain software (referred to as application P in this example), and the time interval for acquiring current consumption information by the software current consumption acquisition unit 22 and the terminal current consumption acquisition unit 23. (Time interval from time T1 to time T4) is shown. In this example, this time interval is predetermined.
It is assumed that history information (log) of usage status of each software is stored.

In this example, the software consumption current acquisition unit 22 and the terminal consumption current acquisition unit 23 acquire the current consumption information for each time interval obtained by dividing the time interval into a plurality of time intervals. Here, as an example, the time interval from time T1 to time T4 is 3 hours, the time interval from time T1 to time T2, the time interval from time T2 to time T3, and from time T3 to time T4. Each time interval is 1 hour.
In this example, the software is operating in the background in order to diagnose software that consumes the power of the battery 13 wastefully in the background even though it has not transitioned to the foreground (not used by the user). When (only) consider the power consumption (get that information).

First, in the time interval from time T1 to time T2, the app P transitions from the background state to the foreground state, and then transitions to the background state. This foreground state lasted for x (where x is greater than 0) seconds.
The software current consumption acquisition unit 22 determines that the time (x seconds) that the application P occupied the foreground is equal to or less than a predetermined threshold, and the application P is in the background in the time interval from time T1 to time T2. Judgment is considered to have been performed. Then, the software current consumption acquisition unit 22 calculates the current consumption C1 [mAh] by the application P based on the history information (resource log) of the resource 12 related to the application P for the time interval from the time T1 to the time T2. And get that information.

Next, in the time interval from time T2 to time T3, the application P transitions from a state in the background to a state in the foreground, and then transitions to a state in the background. This foreground state lasted for y (y is a value greater than 0 and greater than x) seconds.
The software consumption current acquisition unit 22 determines that the time (y seconds) that the app P occupied the foreground exceeds a predetermined threshold, and the app P operated in the foreground during the time period from time T2 to time T3. Judgment that it is considered (used by the user) is performed. Then, the software current consumption acquisition unit 22 regards the current consumption C2 [mAh] by the application P as zero (0) and acquires the information for the time interval from time T2 to time T3.

Next, in the time interval from time T3 to time T4, the application P continued to be in the background. The state in the foreground lasted 0 seconds.
The software current consumption acquisition unit 22 determines that the time (0 seconds) that the application P has occupied the foreground is equal to or less than a predetermined threshold, and the application P is in the background in the time period from time T3 to time T4. Judgment is considered to have been performed. Then, the software consumption current acquisition unit 22 calculates the consumption current C3 [mAh] by the application P based on the history information (resource log) of the resource 12 regarding the application P for the time interval from the time T3 to the time T4. And get that information.

  As described above, the software current consumption acquisition unit 22 calculates (C1 + C2 + C3) [mAh] as the current consumption of the application P (current consumption in the background in this example) in the time interval from time T1 to time T4. , Get that information.

  As a specific example, when the user frequently uses the application P, the application P is often in the foreground, and the current consumption at that time is regarded as zero. For this reason, it is considered that the application P is unlikely to be a presentation target. Furthermore, when the application P does not operate in the background, it is considered that it is not a presentation target. Conversely, if the user does not use the app P much, but the app P often operates in the background, the app P is likely to be a presentation target.

The specific example of the effect acquired in the portable terminal device 1 is shown.
In the mobile terminal device 1, whether or not the currently installed software 101-1 to 101-N is useless that greatly affects the duration of the battery 13 is determined based on whether the current behavior of other software or the user's Judgment can be made in consideration of usage.

  As a specific example, when the current consumption of a certain application (referred to as application Q in this example) is Papp, the total current consumption of the mobile terminal device 1 is Pall, and the predetermined discharge amount is Ctarget, the formula (1 ), It is possible to calculate the amount of change in the arrival time up to a predetermined discharge amount (battery effect) when the app Q is operable and inoperable.

[Equation 1]
Battery Effect
= (Papp / Pall) × {Target / (Pall-Papp)} (1)

  In Expression (1), the first term on the right side indicates the ratio of the current consumption of the application Q to the total current consumption of the mobile terminal device 1. In Expression (1), the second term on the right side indicates the arrival time to a predetermined discharge amount when the application Q is disabled. From formula (1), it can be seen that the influence on the battery 13 changes depending on not only the current consumption of the app Q but also the overall current consumption of the mobile terminal device 1.

  For example, it is assumed that there is an application Q1 that consumes 5 mA (= Papp) and an application Q2 that consumes 10 mA (= Papp). Further, it is assumed that the current consumption of the entire mobile terminal device 1 is 155 mA (= Pall). In this case, when the applications Q1 and Q2 are changed from the operable state to the inoperable state, the remaining amount of the battery 13 is changed from 100% to 15% (if the capacity of the battery 13 is 2700 mAh, Ctarget = 2295 mAh). Consider the amount of change in arrival time to reach. This change amount is [(5/155) × {2295 / (155-5)}] = about 30 minutes for the application Q1, and [(10/155) × {2295 / (155-10) for the application Q2. )}] = About 60 minutes.

However, consider the case where the overall current consumption is reduced to 50 mA (= Pall) depending on how the user uses it. In this case, the amount of change is [(5/50) × {2295 / (50-5)}] = about 5 hours for the application Q1, and [(10/50) × {2295 / (50-10)}] = about 11 hours.
Thus, when the current consumption of software does not change with time, the reduction effect of the current consumption changes depending on the overall current consumption of the mobile terminal device 1. For this reason, in this embodiment, it is easier for the user to understand, and it is possible to induce an action for disabling the software.

As described above, the mobile terminal device 1 according to the present embodiment reduces power consumption according to the number and type of software 101-1 to 101-N that can be different for each mobile terminal device 1 or the usage status. From this point of view, the software to be presented can be determined. For example, the mobile terminal device 1 specifies the current consumption of each of the software 101-1 to 101-N for each software 101-1 to 101-N, and the battery 13 due to the disabling of the software that changes depending on the usage of the user. The degree of influence on the duration time is analyzed, and software that is not so much used by the user among the software 101-1 to 101-N having a large influence is specified and presented.
As described above, the mobile terminal device 1 according to the present embodiment can support reduction in power consumption.

In addition, the software determination device is a first acquisition unit (in this embodiment, a software consumption current acquisition unit 22) that acquires information on an index value of power consumption for the part of software and the predetermined standard.

Information on the degree of influence is acquired based on the information and the information acquired by the second acquisition unit.

Here, in the present embodiment, the current consumption is used as an index value of power consumption, but other index values may be used. As another index value, for example, power consumption itself may be used.
In the present embodiment, the battery 13 that is a secondary battery is used as the power source. However, any power source may be used.
Further, in the mobile terminal device 1 according to the present embodiment, software that has a large influence on the battery 13 and has a low degree of use by the user is presented to the user, and the operation is disabled (for example, deletion by uninstallation). As another configuration example, the mobile terminal device 1 may disable the operation, invalidate, or forcibly terminate the software determined as a target without performing such presentation.
