1. An electronic device comprising:
a CPU; and
a memory storing a program which, when executed by the CPU, causes the electronic device to function as the following units:
a power receiving unit that receives power from a first battery and receives power from a second battery;
an acquisition unit that acquires from the first battery a plurality of information relating to the first battery, including information of a discharge current of the first battery and acquires from the second battery a plurality of information relating to the second battery, including information of a discharge current of the second battery; and
a control unit that calculates a first operable time for which the electronic device can operate using power from the first battery based on the plurality of information relating to the first battery acquired by the acquisition unit and calculates a second operable time for which the electronic device can operate using power from the second battery based on the plurality of information relating to the second battery acquired by the acquisition unit,
wherein in a first mode in which the power receiving unit receives power from the first battery and does not receive power from the second battery, the control unit calculates the first operable time based on the plurality of information relating to the first battery acquired from the first battery, and calculates the second operable time based on information other than the information of the discharge current of the second battery among the plurality of information relating to the second battery acquired from the second battery and the information of the discharge current of the first battery acquired from the first battery.
