ABSTRACT:
A logical battery partitioning approach is disclosed. In one embodiment, a power management system in a portable computing device having a plurality of subsystems can include: (i) a battery coupled to a plurality of subsystems; (ii) a first battery variable provided to a first subsystem to indicate a characteristic of a first logical battery partition; and (iii) a second battery variable provided to a second subsystem to indicate a characteristic of a second logical battery partition. A battery variable can include an accessibility control, or a percent of battery power available, for example.
