Watch the video again. Look at how the iPhone XS was SLOWER in loading Asphalt 9. You seem to be trying to find an excuse as to how a $300 phone is competitive and in some respects superior to the $1000 oneOpening an app is not practical usage. It's how fast the app gets it's work done, which the iphone will demolish. As far as how many people render using imovie, I do and do it frequently to edit movies that I share with my family. I daresay between apps like clips and imovie there may be more usage than you postulate.
