Abstract:

A mobile electronic device with an enhanced battery pack construction is shown. The mobile electronic device () includes: a housing () including a front housing () and a rear housing () having a reservoir area (); a user interface () connected to the front housing (); and a battery pack () including a planar inwardly facing surface () and a nonplanar outwardly facing surface (), the nonplanar outwardly facing surface () being substantially complementarily configured to be received in the reservoir area () of the rear housing (). Advantageously, this construction helps to provide a uniquely shaped mobile electronic device with enhanced ergonomics, adapted to be comfortably held in a user's hand and can conform to a user's palm. Advantageously, this construction is adapted to accommodating expansion and contraction of the battery pack (), when it comprises a Lithium Ion Polymer, in one embodiment.
