Abstract

An electronic device, method, and computer readable medium for a functional mode aware resource management. The electronic device includes a memory and at least one processor. The at least one processor is coupled to the memory. The at least one processor is configured to identify when an amount of a system resource is below a minimum resource threshold. The at least one processor is also configured determine a functional mode of the electronic device. The at least one processor is further configured to identify one or more processes not corresponding to the functional mode that are running on the electronic device. The at least one processor is further configured to terminate at least one of the one or more processes not corresponding to the functional mode when the amount of the system resource is below the minimum resource threshold.
