Battery management system and method
First Claim
1. A mobile device having a battery that supplies power to a plurality of subsystem functions, comprising:
- a battery monitoring circuit that generates a battery capacity signal based on a present capacity measurement of the battery;
an interface that receives an input allocation of battery capacity among the subsystem functions; and
a battery management module responsive to the input allocation and the battery capacity signal, and which selectively disables each subsystem function when each subsystem 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.

13. A method for managing a plurality of subsystems of a mobile communication device powered by a battery, comprising:
-
associating an enable condition with each of the subsystems;
monitoring a present battery condition of the battery;
comparing the present battery condition with the enable conditions of each of the subsystems to determine if a disable condition has been met for each subsystem; and
selectively disabling each subsystem if the disable condition has been met for the subsystem. - View Dependent Claims (14, 15, 16, 17, 18)
