## Abstract

According to one embodiment, an electronic device includes a charging controller, a first information detector, an elapsed time information detector, and a charging instruction module. The controller performs control for charging a battery with a first charging value. The first information detector detects first use date and time information stored in a storage unit of the battery. The elapsed time information detector obtains elapsed time information based on the detected first use date and time information, and detects whether the elapsed time information corresponds to a preset value. The charging instruction module provides an instruction to change a charging value to a preset second charging value when the elapsed time information corresponds to the preset value.

## Claims

### Claim 1

An electronic device comprising:
a charging controller configured to perform control for charging a battery with a preset first charging value;
a first information detector configured to detect first use date and time information stored in a storage unit of the battery;
an elapsed time information detector configured to obtain elapsed time information based on the detected first use date and time information, and detect whether the elapsed time information corresponds to a preset value; and
a charging instruction module configured to provide an instruction to switch a charging value from the first charging value to a preset second charging value and charge the battery when the elapsed time information corresponds to the preset value.

### Claim 2 (depends on 1)

The electronic device of claim 1, wherein when the first use date and time information is not detected, start date and time information of start of an OS is stored as the first use date and time information.

### Claim 3 (depends on 1)

The electronic device of claim 1, wherein when the elapsed time information does not correspond to the preset value, an instruction to charge the battery with the first charging value is provided.

### Claim 4 (depends on 1)

The electronic device of claim 1, wherein the first use date and time information is detected in accordance with start of an OS.

### Claim 5 (depends on 1)

The electronic device of claim 1, wherein the elapsed time information is obtained in accordance with the instruction to charge the battery.

### Claim 6 (depends on 1)

The electronic device of claim 1, further comprising a second charging value storage unit configured to store the switched second charging value.

### Claim 7 (depends on 1)

The electronic device of claim 1, wherein the battery comprises a first use date and time information storage unit configured to store the first use date and time information.

### Claim 8 (depends on 1)

The electronic device of claim 1, wherein the charging instruction module comprises a detection information storage unit configured to store information used to detect whether the elapsed time information corresponds to the preset value.

### Claim 9

A method for controlling an electronic device, comprising:
performing control for charging a battery with a preset first charging value;
detecting first use date and time information stored in a storage unit of the battery;
obtaining elapsed time information based on the detected first use date and time information, and detecting whether the elapsed time information corresponds to a preset value; and
providing an instruction to change a charging value to a preset second charging value and charge the battery when the elapsed time information corresponds to the preset value.

### Claim 10

A computer-readable, non-transitory storage medium having stored thereon a computer program which is executable by a computer, the computer program controlling the computer to execute functions of:
performing control for charging a battery with a preset first charging value;
detecting first use date and time information stored in a storage unit of the battery;
obtaining elapsed time information based on the detected first use date and time information, and detecting whether the elapsed time information corresponds to a preset value; and
providing an instruction to change a charging value to a preset second charging value and charge the battery when the elapsed time information corresponds to the preset value.
