  In this paper we present the preliminary measurement results of harvesting
radio frequency(RF) energy from the mobile phones. The aim is to revolutionize
the way mobile phones are being charged and paving a way of charging the future
mobile phones through RF energy harvesting. In order to measure the amount of
energy that can be harvested, mobile phones from two different manufactures
namely Asus and Samsung have been used. It was shown that depending on the
manufacturer it is possible to harvest 1.53 joules amount of energy per day.
