Battery Management System And Method

A method for managing a plurality of subsystems in a mobile communication device having a battery, comprising:

• monitoring a present condition of the battery;
• comparing the present battery condition with an enable condition of the plurality of subsystems to determine if a disable condition has been met;
• and
• disabling a subsystem in the plurality of subsystems if the disable condition has been met for the subsystem;
• wherein the enable condition is a threshold temperature associated with the subsystems, the present battery condition is a battery temperature measurement, and the disable condition is met when the battery temperature is less than the threshold temperature for a subsystem.

A mobile communication device, comprising

• a battery for supplying power to a plurality of subsystems of the mobile communication device;
• a battery monitoring circuit for monitoring a present battery condition of the battery;
• and
• a battery management module for comparing the present battery condition with an enable condition of the plurality of subsystems to determine if a disable condition has been met, and for selectively disabling a subsystem in the plurality of subsystems if the disable condition has been met for the subsystem;
• wherein the enable condition is a threshold temperature associated with the subsystems, the present battery condition is a battery temperature measurement, and the disable condition is met when the battery temperature is less than the threshold temperature for a subsystem.
