Systems and methods for predicting remaining battery capacity
First Claim
1. A system that predicts remaining battery capacity for a battery used by a device having a plurality of operating modes, the system comprising:
- a memory that stores indicia of remaining battery capacity, and for each mode of the plurality of modes respective indicia of an increment of battery capacity consumption; and
a circuit that determines a duration of operating in a particular operating mode, recalls from memory a particular increment of battery capacity consumption in accordance with the particular operating mode, and stores in the memory indicia of battery capacity remaining in accordance with recalled indicia of remaining battery capacity adjusted for the particular increment of battery capacity consumption.

Abstract
A system according to various aspects of the present invention predicts remaining battery capacity for a battery used by a device. The system includes a memory that stores indicia of remaining battery capacity and a plurality of predefined increments of battery capacity consumption. The system further includes a circuit that determines a duration of operating corresponding to one or more of the increments and stores in the memory a predicted remaining battery capacity, adjusted in accordance with the duration and the one or more increments. Other systems, according to various aspects of the present invention, further include a display indicating remaining battery capacity, for example, as a percentage of initial battery capacity, and/or temperature compensation.
