On a high end phone such as yours, it should not be all that surprising that the performance is good!

On my low end Samsung J3, it is rather choppy, but I feel it can be improved, given that this animation is lovely and smooth: http://campoallecomete.it/#!/en

I think people assume rather quickly that animation in a mobile browser will be janky. Truth is, if done well, it really doesn't need to be.
