BATTERY-CHARGING APPARATUS AND METHOD OF ELECTRONIC DEVICE
First Claim
1. A method of charging an electronic device, the method comprising:
- detecting a connection of a charger;
checking a charging power and a discharging power of a battery while charging the battery with an output of the charger;
determining whether the electronic device is in a normal charging state according to a difference between the charging and discharging powers;
restricting, when the electronic device is in an abnormal charging state, a supply of operation power from the battery; and
supplying, when the electronic device is in the normal charging state, the operation power from the battery.
