Battery Not Included

Scientists in The U. S. A. say they have created the first battery~free mobile phone (Metro, 7~ 7~17),
signalling the end of chargers.
It makes and receives calls using only a few microwatts of power which it gets from light or latching on to wi~fi signals .

Also it uses 'almost zero power' by encoding speech vibrations from the phone  into a radio
signal , The University Of Washington said.
The companies that produce mobile phone batteries and chargers will be watching this closely
because this has the potential to affect their profits .
