Battery management system and method
First Claim
1. A battery management system for managing a plurality of subsystems of a mobile communication device powered by a battery, comprising:
- means for monitoring a present battery condition of the battery;
means for comparing the present battery condition with an enable condition of the plurality of subsystems to determine if a disable condition has been met, wherein the enable condition and the disable condition are set by a user of the mobile communication device; and
means for selectively disabling a subsystem in the plurality of subsystems if the disable condition has been met for the subsystem.

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.
