1. An electronic apparatus comprising:
a secondary battery;
a first power feeder that feeds power to the secondary battery;
a second power feeder that feeds power to the secondary battery at a current larger than a current fed by the first power feeder; and
a processor configured to:
detect a voltage of the secondary battery;
determine a remaining power of the secondary battery based on a comparison of the detected voltage with a first reference value that is a predetermined value set in accordance with the current fed by the first power feeder; and
determine the remaining power of the secondary battery based on a comparison of the detected voltage with a second reference value that is a predetermined value set in accordance with the current fed by the second power feeder and that is higher than the first reference value.
