ABSTRACT:
A portable terminal and power supply control method are provided. The portable terminal having a power supply control feature includes a main battery for supplying power to the portable terminal, an auxiliary battery for supplying power to the portable terminal independently of the main battery, a switch module for controlling the power supply of the main battery and auxiliary battery, and a power unit controller for controlling on-off settings of the switch module and for disconnecting, when a battery level of the main battery is higher than that of the auxiliary battery, the auxiliary battery from the main battery. The battery levels of the main battery and auxiliary battery are measured and are controlled to prevent charging of the auxiliary battery with a charge current from the main battery through switch settings.
