Systems, apparatuses, and methods for detecting a foreign object on a wireless power charging region are described. A circuit can detect an object inductively coupled to a wireless power transmitter. The circuit can further measure an input parameter prior to a power transfer stage, the input parameter can be one of an input current and an input power. The circuit can further compare the measured input parameter with a predetermined value. The circuit can further determine whether the object is a foreign object or the wireless power receiver based on a result of the comparison between the measured input parameter with the predetermined value.
