Whether CPU is maintained in the working condition of corresponding occupancy level.Mobile terminal adds up CPU by level counter and continuously maintained
The number of each occupancy level, the number that occupancy level is continuously maintained as CPU reach the 3rd threshold corresponding with the occupancy level
During value, then it can assert that CPU is stable in the working condition of the occupancy level.For example, to L1, L2, L3 and L4, one is set respectively
Corresponding 3rd threshold value is c1, c2, c3 and c4, and the number that L1 ranks are continuously maintained as CPU reaches c1, then assert that CPU is stable
In L1 working condition.Further, the 3rd threshold value corresponding to each occupancy level, can subtract with the increase of occupancy level
It is small, for example, the 3rd threshold value corresponding to L1, L2, L3 and L4 is c1, c2, c3 and c4, wherein, c1>c2>c3>C4, such as, c1 5
Secondary, c2 is 4 times, and c3 is 3 times, and c4 is 2 inferior, but not limited to this.In one embodiment, if multiple continuous maintenances simultaneously be present
Number reach corresponding to the 3rd threshold value occupancy level, then choose highest level occupancy level as CPU stably work
State.
