Abstract

An object of the present invention is to provide a portable electronic device, a method, and a computer-readable recording medium, all of which are capable of preventing the portable electronic device from being taken away by another person while charging. The smartphone includes: a touch-screen display; a power receiving unit that receives power from electromagnetic waves that are supplied from a battery charger; and a controller that restricts execution of predetermined functions in a case in which the portable electronic device is separated from the battery charger in a state where the battery charger is supplying electromagnetic waves to the power receiving unit, and enables the predetermined functions to be executed in a case in which an authentication operation is performed via the touch-screen display after restricting execution of the predetermined functions.

Claims

1. A portable electronic device, comprising:

an operation unit;

a notification unit including a speaker;

a power receiving unit configured to receive power from electromagnetic waves that are supplied from a battery charger; and

a control unit configured to cause the speaker to make a sound notification in response to a determination that the portable electronic device is separated from the battery charger, in a state where the battery charger is supplying the electromagnetic waves to the power receiving unit.

2. The portable electronic device according to claim 1, wherein

the operation unit is defined by a touch-screen display, and

the control unit is configured to, in the state where the battery charger is supplying the electromagnetic waves to provide charging power to the power receiving unit,

cause the notification unit to make the sound notification, in response to the determination that the portable electronic device is separated from the battery charger and the electromagnetic waves are no longer supplied from the battery charger, and

accept an authentication operation by a user'"'"'s input via the operation unit.

3. The portable electronic device according to claim 2, wherein,

the control unit is configured to

restrict execution of predetermined functions when the portable electronic device is separated from the battery charger in the state where the battery charger is supplying the electromagnetic waves to provide the charging power to the power receiving unit, and

cause the speaker to make the sound notification when the authentication operation is not performed within a predetermined period of time after restricting the execution of the predetermined functions.

4. The portable electronic device according to claim 3,

wherein, in the state where the battery charger is supplying the electromagnetic waves to provide the charging power to the power receiving unit, in a case in which the portable electronic device is separated from the battery charger, the control unit is configured to cause the touch-screen display to display the predetermined period of time.

5. The portable electronic device according to claim 4,

wherein, in the state where the battery charger is supplying the electromagnetic waves to provide the charging power to the power receiving unit, when the portable electronic device is separated from the battery charger, the control unit is configured to cause the touch screen display to display countdown for the predetermined period of time as an initial value.

6. The portable electronic device according to claim 5,

wherein, in a case in which the battery charger starts again supplying the electromagnetic waves to provide the charging power to the power receiving unit while the countdown is being displayed, the control unit is configured to suspend the displaying of the countdown.

7. The portable electronic device according to claim 6,

wherein, in a case in which the portable electronic device is separated from the battery charger after suspending the displaying of the countdown, the control unit is configured to cause the display unit to display countdown for the predetermined period of time as an initial value.

8. The portable electronic device according to claim 1, wherein the control unit is configured to cause the speaker to make the sound notification to prevent the portable electronic device from being taken away by another person while the battery charger is supplying the electromagnetic waves to the power receiving unit.

9. A portable electronic device, comprising:

an operation unit;

a notification unit including a receiver;

a power receiving unit configured to receive power from electromagnetic waves that are supplied from a battery charger; and

a control unit configured to cause the receiver to make a sound notification in response to a determination that the portable electronic device is separated from the battery charger, in a state where the battery charger is supplying the electromagnetic waves to the power receiving unit.
