My terminal window was really spammed.

After boot, the phone runs smooth but after some time it lags heavily. As you can see from the attached output of the "top" command, Unity8 consumes 23% of CPU power when the screen is TURNED OFF (command run via adb). When the screen is on, this figure is much higher and sometimes rises up to 60%.
