Abstract: A system for, and method of, extending useful life of a battery and a battery-powered device incorporating the system or the method. In one embodiment, the system includes: (1) a charge detector operable to detect a charge level contained in the battery, (2) a use modeler coupled to the charge detector and operable to receive data from the charge detector and develop a model of the charge level over time and (3) a charge activator coupled to the use modeler and operable to forego an opportunity to charge the battery when a sufficient charge remains in the battery to last until a full charge can likely be undertaken.
