My Nokia 7 plus is on July security patch that is the latest patch but animations like swiping right to access Google now and also switching between apps,
For me android P beta = no ability to select mics in video app, no ozo audio. Also some issues with nova launcher. Other than that it's been ok... but as said, for me, stutters not fixed, just slightly improved. Battery life seems similar to before.
just turn off that news feed on the left side of stock launcher and the stutters is gone, and everything is faster after some time
i know that it can be better in terms of fluid animations, because it is pure android, but disabling that feed in stock launcher keeping things quite good... try to NOT use nova or any another launcher, disable that feed, and use it for few days..
