The embodiment of the invention relates to a resource management method and device, a mobile terminal and a computer readable storage medium. The above method comprises the following steps that: when a detection result shows that an application in a preset application list operates in a foreground, determining a corresponding foreground process; collecting the occupancy rate of each CPU (Central Processing Unit) in multi-core CPUs; selecting the CPU with the lowest occupancy rate, and distributing the foreground process to the CPU with the lowest occupancy rate to be operated; and when a background process operates on the CPU with the lowest occupancy rate, distributing the background process to other CPUs to be operated. By use of the above resource management method and device, the above mobile terminal and the above computer readable storage medium, a situation that the application which operates in the foreground slowly operates since resources are seized can be reduced.
