I have some rant here:
Reported this while in beta but they haven't fixed it.
The thing is Nokia 8 is using an outdated interactive governor while many OEMs has switched to schedutil, this including Google's Pixel. But the thing with Nokia's governor is even worse it uses 800MHz on all four bigger cores in standby/sleep while it should use 300MHz instead. This leads to a battery drain and sounds like really dumb bug, I can't imagine it was made on purpose as a working standby freq for SDM835 is exactly 300MHz. For those who interested, you could use CPU monitor like Trepn or CPUFloat from the Play Store to see how freq are acting.
Hopefully mods could push this to a product management team. Another thing a lack of sRGB implementation is also inexcusable as it's part of AOSP
