Abstract

An electronic apparatus includes a secondary battery, a first power feeder, a second power feeder, and a processor. The first power feeder feeds power to the secondary battery. The second power feeder feeds power to the secondary battery at a current larger than a current fed by the first power feeder. The processor detects a voltage of the secondary battery, and determines a remaining power of the secondary battery based on a comparison of the detected voltage with first or second reference values. The first reference value is a predetermined value set in accordance with the current fed by the first power feeder. The second reference value is a predetermined value set in accordance with the current fed by the second power feeder, and is higher than the first reference value.
