PORTABLE ELECTRONIC APPARATUS AND CHARGING APPARATUS
First Claim
1. A portable electronic device comprising:
- a battery;
a direct current (DC) power source;
a first device that consumes a first amount of power during operation;
a second device that consumes a second amount o f power during operation, the second amount of power being more than the first amount of power;
a first switch provided in a charging path between the DC power source and the battery;
a second switch provided in a path for supplying power from the battery to the second device; and
a charging control circuit configured to control charging the battery by connecting the first switch when external power is supplied via the DC power source, and control the second switch to be connected and the first switch to be disconnected when the second device is operated during the charging.

17. A method of charging a battery in a portable electronic device, the method comprising:
-
determining whether external power is supplied via a DC power source; connecting a first switch provided in a charging path between the DC power source and a battery when it is determined that external power is supplied via the DC power source; determining whether a device that consumes a larger amount of power during operation as compared to another device in the portable electronic device is in operation; and connecting a second switch provided in a path for supplying power from the battery to the second device and disconnecting the first switch when it is determined that the device is in operation. - View Dependent Claims (18, 19)
