Abstract

An electronic device includes: a first processor; a load that operates with power supplied by a rechargeable battery; and a first sensor that obtains information on an output voltage of the rechargeable battery. The first processor determines whether the rechargeable battery is in a low usage state with regard to power supply by the rechargeable battery. Based on the information obtained by the first sensor, the first processor determines a degree of decrease in the output voltage over a period of time during which the rechargeable battery is determined to be in the low usage state. Based on the determined degree of decrease, the first processor detects a deterioration of the rechargeable battery.
