Abstract
An electronic apparatus comprising: a main body including a reception unit and a processing unit; and a power supply device switches between an operation state for supplying power from an external power source to the main body and a standby state for supplying power from a secondary battery to the reception unit without supplying power from the power source to the main body. Charging of the battery with power from the power source is performed during the operation state and is terminated when a value indicating power level of the battery reaches a threshold value Vt satisfying (discharge lower limit VL+Vs)≦Vt<charge upper limit VH, Vs denoting a decrease in power level occurring when power from the battery is supplied to the reception unit for an estimated maximum duration of the standby state within a time period having a unit time length.
