Bro, actually not true la.
Depending on work load , if the things you are looking at are single to duo core cpu usage, then 675 is equal and even slightly edge out 845 due to the new big core., like moba, video streaming or Facebook (single to 2 Appa open) and under these situation 675 is more power efficient.
If you are looking at multiple cores usage eg pubg, or playing h265 or h264x encoded video, or multiple heavy apps open and running in the background, then overall 845 better.
But anything with gaming 845 due to the better graphics will have advantage but eat up more battery overall, compared 845 playing pubg va 675 playing pubg
Camera advantage goes to note 7 esp native with gcam even though pocco also can gcam.
As for battery life proven with review generally 675 better than 845.
As for design it’s not subjectively la come on note 7 is objectively obvious much more better than pocco just that for bro who goes for pocco don really care so they disregard leh. Credit due when credit due la
So depends on usage and how battery life and camera is impt to you.
Note 7 pro is a slightly younger bro/ sis to pocco F1 (if pricing not taken into account or if you take China pricing only )
Esp if you let the girl choose most (not all) girls will choose Note 7 la
