Abstract: Battery life of mobile phone is always been a problem for manufacturers. People are complaining about their mobile’s battery life, that they don’t have long battery life and they have to charge their phone several times. In this paper a new idea is shown to charge your mobile phone automatically by the using the microcontroller circuit with timer. By this concept mobile will not be over charged and battery life would be long and efficiency of battery would remain same as previous. In this concept we used two circuit one transmitter and other receiver circuit, Transmitter circuit have AC to DC rectifier circuit and then it is modulated by pulse width modulator circuit .It is connect to the primary coil to transmitter by the Faraday’s law of mutual induction secondary coil will get induced emf then AC to DC bridge circuit it is used to connect the charger pin to the mobile port. A microcontroller with timer circuit is used to avoid the overcharge the battery.
Keywords: Step down transformer, Bridge Rectifier, transmitter circuit, PWMS (pulse width modulator), Receiver circuit, and Microcontroller circuit with timer coding.
