All these phone irrespective of their manufacturer and batteries have to be put recharge after the battery has drained out the main objective of this current proposal is to make recharging of the mobile phone independent of their manufacture and battery maker. In this paper a new proposal has been made so as to make the recharging of the mobile phones is done automatically as you talk in your mobile phone!. This is done by using microwaves. the microwave signal transmitted from the transmitter along with message signal using special kind of antennas called slotted wave guide antenna at a frequency of 2.45GHz .There are minimal additions ,which have to be made in the mobile handsets ,which are the addition of sensor, a "rectenna" and a filter with the above setup, the need for seperate chargers for mobile phone is eliminated and makes charging universal .Thus the more you talk the more is your mobile charge level ,With this proposal the manufacture would be able to remove the talk time and battery stand by from their phone specifications
