Cell phone battery system with back-up reserve

Abstract

The invention relates to a cell phone battery pack and a method of providing backup battery power to a cell phone. The cell phone battery pack is configured to be positioned within a cell phone. The battery pack includes a first battery, a second battery and a means to allow switching between the first battery and the second battery for powering the cell phone. The first battery and the second battery may differ in one or both of size and capacity.
