An apparatus and method for determining a status of a power unit in a portable terminal are provided. The apparatus includes a power unit for supplying power to a internal circuit, a resistor located between the power unit and the internal circuit, and a voltage determination unit for determining an amount of a current consumption by the internal circuit by considering a difference between a first voltage between the power unit and the resistor and a second voltage between the resistor and the internal circuit, and for determining status information of the power unit by compensating for a voltage drop of the first voltage in accordance with the amount of the current consumption.
