Watch the video you posted. The Note wrecked the iPhone X in ram management. It’s obvious iOS 11 needs 4GB of RAM minimum.
Only because one phone has TWICE the RAM than the other. Obviously it'll win?
Apple balances RAM capacity and battery life. People want fast phones, want phones that can last for days, want phones that comes with 8GB RAM etc. Technology ain't there yet to balance all these features.
Let's be real.
I've seen you posting around here, Radon. Even if you were to use the Note 8, you'll whine about the delay when pressing the screen to launch apps.
