new flagship chips are kinda pointless unless you care about photography or mobile vr (lol).
2016 brought us SD625: which on stockish android is basically the same experience as a SD820 outside of games and HDR processing, with tremendous System on Time.
i'm more curious about battery life for the new 10nm process than benchmark times.
There's still a lot that can be done, but I doubt the 835 fixes it all.
Read/Write speed still has ways to go. Multithreaded/Core is solid, but single core still lags. Bandwidth could still be improved.
Oh and more effective switching between BIG little as well as spinning up and down as needed.
I also still think Chrome has a long way to go and a lot of performance on Android isn't the chipset, but rather Chrome.
Feels like also since even base line 430 phones have better GPUs these days that Google should try and leverage more GPU acceleration in the OS.
