Abstract

A novel portable electronic device comprising a first housing portion (106) having a first battery (135) integrally associated with said first housing portion and a second housing portion (104) having a second battery (102) operatively coupled to an external surface of the second housing portion. Also, a method for coupling power to a portable electronic device comprises steps of providing a recessed region in a first housing portion for receiving a first battery and operatively coupling a second battery to an external surface of a second housing portion.
