## Abstract

An electronic device includes a storing unit which is provided on a battery pack and which retains power information of the battery pack, an acquiring unit which is provided in the main unit and which acquires the power information of the battery pack from the storing unit, and a control unit which is provided in the main unit and which controls the operation of the main unit based on the power information of the battery pack.

## Claims

### Claim 1

(canceled)

### Claim 2

An electronic device, comprising:
a battery to supply power to the device, wherein the battery is installed in the device and the battery includes storing circuitry that stores power information of the battery; and
control circuitry provided in the device that acquires the power information of the battery from the storing circuitry, and that controls an operating frequency of the device based on the power information of the battery.

### Claim 3 (depends on 2)

The device according to claim 2, wherein the power information of the battery is regularly stored by the storing circuitry, and the regularly stored power information is continuously or intermittently acquired by the control circuitry.

### Claim 4 (depends on 2)

The device according to claim 2, wherein the power information includes a maximum amount of power that can be delivered by the battery.

### Claim 5 (depends on 4)

The device according to claim 4, wherein the maximum amount of power is a maximum amount of energy per unit time that can be delivered by the battery.

### Claim 6 (depends on 4)

The device according to claim 4, wherein the maximum amount of power is calculated based on one or more of an ambient temperature, voltage, and deterioration factor.

### Claim 7 (depends on 2)

The device according to claim 2, wherein:
the battery includes a detectable part, the detectable part including a detectable shape or a detectable circuit that enables detection of a type of the battery,
the device includes a detecting part, the detecting part including a detecting shape or a detecting circuit to detect the type of the battery, and
the control circuitry controls an operation of the device based on the power information and the type of the batter detected by the detecting part.

### Claim 8 (depends on 7)

The device according to claim 7, further comprising:
a housing for the battery that includes, on an outer surface thereof, one of a detectable projection and a detectable recess as the detectable part, wherein
the device includes, thereon, as the detecting part, one of a detecting recess into which the detectable projection is to be inserted and a detecting projection to be inserted into the detectable recess.

### Claim 9

A method, comprising:
storing power information in a battery of an electronic device, wherein the battery supplies power to the device and the battery is installed in the device;
acquiring, by control circuitry provided in the device, the power information of the battery; and
controlling an operating frequency of the device based on the power information of the battery acquired in the acquiring.
