Abstract
A portable electronic device and method for measuring electric current of an external electronic device by the portable electronic device are provided. The method includes detecting whether an external device is connected, through the earphone jack, or whether a simple headset is connected through the earphone jack. The earphone jack can pass audio signals from the headset, but if an external device is detected, software is implemented to measure the amplitude of electric current from the external electronic device.
