1. An electronic device comprising:
a battery comprising a positive electrode and a negative electrode;
a processor coupled to the battery and configured to generate instruction information according to a first value of a battery voltage that is between the positive electrode and the negative electrode;
a transceiver configured to instruct a charger to output an output voltage of at least K times the first value by sending the instruction information to the charger, wherein K is a conversion coefficient and is a real number greater than one; and
a conversion circuit comprising a switch-capacitor conversion circuit and configured to convert a charger voltage from the charger into 1/K times the charger voltage.
