Hi Quentin, I tried on a hikey960 with an android kernel 4.19. The used percentile is the 95%, the tests are jankbench list_view and edit_text, and exoplayer. Values are normalized against the menu governor: list_view: frame duration -35% count: +20% energy: +1% edit text: frame duration -45% count: +27% energy: -0.3% For audio and video playback, there is no frame drop. audio - energy: -2.8% video - energy: -3.8% These are preliminary results. -- Daniel -- <http://www.linaro.org/> Linaro.org │ Open source software for ARM SoCs Follow Linaro: <http://www.facebook.com/pages/Linaro> Facebook | <http://twitter.com/#!/linaroorg> Twitter | <http://www.linaro.org/linaro-blog/> Blog
