Oh MiFan.... Picking an iPhone is easy, don't need to bother specs like Android world.... Just follow your pocket, select screen size & storage size. It just work smoothly bcoz it's an iPhone...

*Ignore previous gen X series(yes alot discount)

the latest iPhone 11 are good enough...
but if your pocket thick enough, then sure go 11pro max

Try watch this iPhone 11 vs 11pro after 2 months:
