Battery management system and method
First Claim
1. A battery management system for managing a plurality of subsystem circuits and functions of a mobile communication device powered by a battery, the battery management system comprising:
- a battery monitoring circuit operable to monitor a present battery capacity and generate a battery capacity signal based on the present battery capacity;
a user interface operable to receive a user input allocation of battery capacity among the subsystem circuits and functions; and
a battery management module operable to receive the user input allocation and the battery capacity signal, and selectively to disable each subsystem circuit or function when each subsystem circuit or function has depleted its allocation of battery capacity.

Abstract
A battery management system for managing a plurality of subsystem circuits and functions of a mobile communication device powered by a battery is disclosed. The battery management system includes a battery monitoring circuit, a user interface, and a battery management module. The battery monitoring circuit is operable to monitor a present battery capacity and generate a battery capacity signal based on the present battery capacity. The user interface is operable to receive a user-input allocation of battery capacity among the subsystem circuits and functions. The battery management module is operable to receive the user-input allocation and the battery capacity signal, and to selectively disable each subsystem circuit or function when each subsystem circuit or function has depleted its allocation of battery capacity.

15. A method for managing a plurality of subsystem circuits and functions of a mobile communication device powered by a battery, comprising:
-
allocating battery capacity among the subsystem circuits and functions;
comparing a present battery capacity of a battery to respective amounts of battery capacity depleted by the subsystem circuits and functions; and
selectively disabling each subsystem circuit or function after each subsystem circuit or function has depleted its allocation of battery capacity. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)
