Present handheld devices like Smart phones, can be charged wirelessly using new energy harvesting circuit technique through using the traditional wireless technologies. In this case, Bluetooth with a charging circuit enables a short-range wireless charging of a mobile handheld. This paper present the overview of new process of charging and structure of power charging based on Scotty diode with a real commercial film-type antenna on mobile terminal. So that it may called smart charging, this new circuit improves the efficiency in charging upto 160%, known to be 0. 45 mA, relatively, 5 mA for smart phones.
