Nothing. The iPhone SoC blows every android out of the water. Apple has been dominating mobile performance ever since they went to 64-bit in 2013. That's a decade of leadership in silicon. No android comes close. Not sure what OP is thinking.
So what? The OS is totally locked down. There's nothing to actually do with all that extra compute. Are iPhone games better than Android games? Probably, but I imagine most of the HN crowd isn't into mobile games. Other than that I can't even think of what the better iPhone SOCs would be used for.
I'm saying it's good enough for my use, which is watching YouTube videos, using apps, taking pictures, having a reasonable battery life, making phone calls, sending texts.
It might not be the best possible soc etc. But for $349 it serves me as a daily driver for 3 years without shelling out over $1000
Because each one of those has 3 (Samsung) or 4 (iPhone) major models with wildly different specs, and each of those specs has often times major differences in quality between the two lines.
