Systems and methods for managing current consumption by an electronic device are provided. The electronic device includes first and second clock units. The first clock unit generates a first reference clock signal based on a first current input. The second clock unit generates a second reference clock signal based on a second current input greater than the first current input. The system includes a control module configured to identify an application to be executed. The control module is configured to determine whether the application is associated with a first current consumption level or a second current consumption level greater than the first current consumption level. The control module is configured to select the first or second reference clock signal based on whether the application is determined to be associated with the first or second current consumption level. The system includes circuitry configured to execute the application based on the selection.
