From start till it is shut down, the CPU is continuously running processes. Each process takes part of the CPU cycles. If the CPU is fully loaded then the System Idle Process will be fluctuating around 0-10%.
Once the running processes finish, the CPU will be freed and doing nothing. This is indicated by the System Idle Process (a null process) with more % usage. In this state CPU is running less processes and idle most of the time.
