1. A method for battery management, the method comprising:

monitoring, by a battery management system, a present battery condition of a battery for supplying power to a plurality of subsystems of a mobile communication device, wherein the present battery condition indicates a present operating temperature of the battery, wherein an amount of battery capacity depleted by a subsystem has a relationship to the present operating temperature of the battery;

determining whether the present operating temperature of the battery falls below a power saving mode enable condition for each respective subsystem of the plurality of subsystems, wherein the power saving mode enable condition is set by a user of a mobile communication device, and wherein a first amount of battery capacity depleted by the subsystem when the present operating temperature of the battery is below the power saving mode enable condition is greater than a second amount of battery capacity depleted by the subsystem when the present operating temperature of the battery is above the power saving mode enable condition; and

in response to determining that the present operating temperature of the battery falls below the power saving mode enable condition for one of the respective subsystems of the plurality of subsystems, disabling the one of the respective subsystems of the plurality of subsystems without disabling one or more of a remainder of the plurality of subsystems.

2. The method of claim 1 , further comprising:

notifying the user of the mobile communication device that the subsystem is about to be selectively disabled if the power saving mode enable condition has been met; and

enabling the user of the mobile communication device to abort the selective disabling of the subsystem.

3. The method of claim 2 , further comprising:

modifying the power saving mode enable condition of the subsystem in response to aborting the selective disabling of the subsystem.

4. The method of claim 1 , further comprising:

temporarily disabling the selectively disabling of the subsystem in response to the mobile communication device being coupled to an alternate power source other than the battery.

5. The method of claim 1 , wherein the power saving mode enable condition for each respective subsystem of the plurality of subsystems indicates a minimum present operating temperature of the battery allowed for operation of each respective subsystem of the plurality of subsystems.

6. The method of claim 5 , wherein the minimum present operating temperature of the battery allowed for operation of each respective subsystem of the plurality of subsystems is determined according to a power requirement of each respective subsystem of the plurality of subsystems.

7. The method of claim 5 , wherein the minimum present operating temperature of the battery allowed for operation of each respective subsystem of the plurality of subsystems is determined according to a battery chemistry of the battery.

8. The method of claim 1 , further comprising enabling the disabled one of the respective subsystems of the plurality of subsystems when the present operating temperature of the battery rises above the power saving mode enable condition for the disabled one of the respective subsystems.

monitoring, by a battery management system, a present battery condition of a battery for supplying power to a plurality of subsystems of a mobile communication device, wherein the present battery condition indicates a present operating temperature of the battery, wherein an amount of battery capacity depleted by a subsystem has a relationship to the present operating temperature of the battery;

determining whether the present operating temperature of the battery falls below a power saving mode enable condition for each respective subsystem of the plurality of subsystems, wherein the power saving mode enable condition is set by a user of a mobile communication device, and wherein a first amount of battery capacity depleted by the subsystem when the present operating temperature of the battery is below the power saving mode enable condition is greater than a second amount of battery capacity depleted by the subsystem when the present operating temperature of the battery is above the power saving mode enable condition; and

in response to determining that the present operating temperature of the battery falls below the power saving mode enable condition for one of the respective subsystems of the plurality of subsystem, disabling the one of the respective subsystems of the plurality of subsystems without disabling one or more of a remainder of the plurality of subsystems.

10. The non-transitory, tangible computer-readable storage medium of claim 9 , wherein the power saving mode enable condition for each respective subsystem of the plurality of subsystems indicates a minimum present operating temperature of the battery allowed for operation of each respective subsystem of the plurality of subsystems.

11. The non-transitory, tangible computer-readable storage medium of claim 10 , wherein the minimum present operating temperature of the battery allowed for operation of each respective subsystem of the plurality of subsystems is determined according to a power requirement of each respective subsystem of the plurality of subsystems.

12. The non-transitory, tangible computer-readable storage medium of claim 11 , wherein the minimum present operating temperature of the battery allowed for operation of each respective subsystem of the plurality of subsystems is determined according to a battery chemistry of the battery.

13. The non-transitory, tangible computer-readable storage medium of claim 9 , wherein execution of the computer executable instructions is further for enabling the disabled one of the respective subsystems of the plurality of subsystems when the present operating temperature of the battery rises above the power saving mode enable condition for the disabled one of the respective subsystems.

14. A mobile communication device comprising:

a battery for supplying power to a plurality of subsystems of the mobile communication device;

a battery management system configured to:

monitor a present battery condition of the battery, wherein the present battery condition indicates a present operating temperature of the battery, wherein an amount of battery capacity depleted by a subsystem has a relationship to the present operating temperature of the battery;
