Abstract
A power control manager includes a processor to compute available power from a power source and a comparator to compare the available power to an amount of power to concurrently operate a plurality of sub-systems of an electronic device at full or a predetermined power. The processor generates one or more control signals in response to a decision signal output from the comparator. The control signals may indicate that a maximum power setting is to be set for a first sub-system and a reduced non-zero power setting is to be set for a second sub-system of the plurality of sub-systems. The sub-systems may be different sub-systems of a smartphone or another electronic device.
