To provide a method of calculating capacity of an intelligent battery, the intelligent battery and a portable electronic device capable of allowing for power consumption by a minute current undetectable by a conventional circuit without any special cost required so as to consequently allow an error of capacity data to be smaller. The capacity data in a low electric power consumption mode such as while in a soft-off mode is calculated based on the capacity data acquired by multiplying a consumption electric current value in a low electric power consumption mode acquired in advance by the time that the mode continues and voltage or the capacity data acquired by multiplying the consumption electric power value in the low electric power consumption mode acquired in advance by the time that the mode continues rather than capacity calculation based on the electric current value measured by a current measurement circuit of a battery itself, and so it allows the power consumption in the low electric power consumption mode to be calculated correctly so as to make the error of the acquired capacity data smaller.
