i have the 9570 i9/4k and after upgrading to kernel 4.17 almost all problems are gone, i run nixos + i3 and battery sometimes reports 16h+ but in reality I’ve gotten about 9h. i don’t fire up the 1050 at all as i don’t need it.
Did you consider blogging or writing a guide about it?
There is a mismatch on information about the 9570 with chunk of informations here and there if you Google a lot, but nothing definitely well written yet.
