Not sure if the cpu percentage is normal

The previous question haven't been solved. I send it again. when my video neural network model was running on iphone11, the cpu occupation reached to 31%, is it normal? I am not sure if the value 31% has a serious impact on the other app. So that I would ask for your advice. Previously, I originally expected to lower the cpu percentage by reducing the model op. when I put a model with only 6 biliear_interpolation ops into coreml, the cpu percentage is 20%(equal on cpu, cpuandgpu&all), so I consider if the only coreML scheduling occupy the 20% cpu?
