Abstract
An electronic device includes a charging unit that charges a battery with power supplied from an external device, and a control unit that controls a communication unit of the electronic device such that a communication interval from a start of charging the battery by the charging unit until a battery voltage exceeds a predetermined threshold is shorter than a communication interval after the battery voltage exceeds the predetermined threshold, in a case where power is received from the external device.
Claims8
An electronic device comprising:
- a CPU;
- a memory storing a program which, when executed by the CPU, causes the CPU to function as:
- a charging unit that charges a battery with power supplied from an external device;
- a communication unit that communicates with the external device;
- and
- a control unit that controls the communication unit to perform a predetermined communication for requesting a change of power to be supplied to the electronic device in a case where the battery is being charged by the charging unit,
- wherein the control unit controls the communication unit such that an interval of performing the predetermined communication from a start of charging the battery by the charging unit until a battery voltage exceeds a predetermined threshold is shorter than an interval of performing the predetermined communication after the battery voltage exceeds the predetermined threshold, in a case where the battery is being charged by the charging unit.

- a memory storing a program which, when executed by the CPU, causes the CPU to function as:
- a charging unit that charges a battery with power supplied from an external device;
- a communication unit that communicates with the external device;
- and
- a control unit that controls the communication unit to perform a predetermined communication for requesting a change of power to be supplied to the electronic device in a case where the battery is being charged by the charging unit,
- wherein the control unit controls the communication unit so that an interval of performing the predetermined communication becomes a predetermined interval, in a case where a change amount of battery voltage exceeds a predetermined value in charging of the battery, and controls the communication unit so that an interval of performing the predetermined communication becomes shorter than the predetermined interval, in a case where the change amount of battery voltage does not exceed the predetermined value in charging of the battery.

A method comprising:
- charging a battery by power supplied from an external device;
- communicating with the external device;
- and
- controlling the communicating to perform a predetermined communication for requesting a change of power to be supplied to the electronic device in a case where the battery is being charged by the charging,
- wherein the controlling controls the communicating such that an interval of performing the predetermined communication from a start of charging the battery until the battery voltage exceeds a predetermined threshold is shorter than an interval of performing the predetermined communication after the battery voltage exceeds the predetermined threshold, in a case where the battery is being charged by the charging.
