Abstract

An electronic device includes a charging power determining section and a control section. The charging power determining section determines a state of the charging power with respect to a remaining battery level, with reference to (i) information which indicates whether or not the remaining battery level of a rechargeable battery is lower than a first threshold and (ii) information which indicates whether or not the charging power, which is supplied from an external device to the rechargeable battery, is lower than a second threshold. The control section controls the electronic device to display a result of determination made by the charging power determining section.

First claim

The invention claimed is:

1. An electronic device, comprising:
a charging power determining section configured to determine a state of charging power with respect to a remaining battery level, with reference to (i) information which indicates whether or not the remaining battery level of a rechargeable battery is lower than a first threshold and (ii) information which indicates whether or not the charging power, which is supplied from an external device to the rechargeable battery, is lower than a second threshold; and
a control section configured to control the electronic device to display a result of determination made by the charging power determining section,
the control section controlling the electronic device to display the result so as to indicate that (i) the remaining battery level of the rechargeable battery is lower than the first threshold and (ii) the charging power supplied from the external device to the rechargeable battery is lower than the second threshold.

2. The electronic device as set forth in claim 1 , wherein:
the charging power determining section determines that the remaining battery level is inadequate and that the charging power is adequate, in a case where (i) the remaining battery level is lower than the first threshold and (ii) the charging power is equal to or higher than the second threshold; and
the charging power determining section determines that the remaining battery level and the charging power are inadequate, in a case where the remaining battery level is lower than the first threshold and the charging power is lower than the second threshold.

3. The electronic device as set forth in claim 2 , wherein:
the second threshold is set by the control section so as to be lower (i) in a case where the remaining battery level is equal to or higher than a third threshold than (ii) in a case where the remaining battery level is lower than the third threshold, the third threshold being lower than the first threshold.

4. An electronic device, comprising:
a charging power determining section configured to determine a state of charging power with respect to a remaining battery level, with reference to (i) information which indicates whether or not the remaining battery level of a rechargeable battery is lower than a first threshold and (ii) information which indicates whether or not the charging power, which is supplied from an external device to the rechargeable battery, is lower than a second threshold;
a control section configured to control the electronic device to display a result of determination made by the charging power determining section; and
a temperature sensor configured to detect an internal temperature of the electronic device,
the control section (i) referring to information which indicates whether or not the internal temperature detected by the temperature sensor is equal to or higher than a predetermined temperature threshold, (ii) determining, in a case where the internal temperature is equal to or higher than the predetermined temperature threshold, that the internal temperature is high, and (iii) reducing the charging power in a case where it is determined that the internal temperature is high.

5. The electronic device as set forth in claim 4 , wherein:
the control section controls the electronic device to display a reduction in charging power made by the control section.

6. An electronic device, comprising:
a charging power determining section configured to determine a state of charging power with respect to a remaining battery level, with reference to (i) information which indicates whether or not the remaining battery level of a rechargeable battery is lower than a first threshold and (ii) information which indicates whether or not the charging power, which is supplied from an external device to the rechargeable battery, is lower than a second threshold; and
a control section configured to control the electronic device to display a result of determination made by the charging power determining section;
the control section invoking a restriction on a processing speed of the electronic device, in a case where the remaining battery level is lower than a third threshold which is lower than the first threshold; and
the control section removing the restriction, in a case where the remaining battery level is equal to or higher than the third threshold or in a case where the remaining battery level is lower than the first threshold and the charging power is equal to or higher than the second threshold.
