Abstract
In an electronic device in which a charge path to a secondary battery and a signal path to a reception device are partially shared and a receiving-time current due to the reception is made to be a charging current for the secondary battery, even in a case in which the voltage across the secondary battery is close to a maximum voltage, by bypassing the charging current due to the signal reception, the voltage across the secondary battery is controlled so as not to exceed the maximum voltage.
