Mobile equipment and CPU load control method and device thereof

The embodiment of the invention provides mobile equipment and a CPU load control method and device thereof. The method comprises the following steps: acquiring a historical occupancy rate of an OTA upgrade component to a mobile equipment CPU, and determining a target sub-component from the OTA upgrade component according to the historical occupancy rate; after the target sub-component is determined, the current occupancy rate of the CPU of the mobile equipment is monitored when OTA upgrading is carried out, and the occupancy rate of the target sub-component to the CPU of the mobile equipment is delayed when it is monitored that the current occupancy rate meets the preset limiting condition, so that the current load of the CPU of the mobile equipment can be reduced, and the current load of the CPU of the mobile equipment is reduced in the running process of the OTA upgrading component. And the situation of OTA upgrading failure or even downtime is avoided. And furthermore, on the premise that the hardware of t
