And yet, despite benchmark numbers, my point still stands. For all the usage I listed above, my old Android is perfectly serviceable. Not once I was using it and thought a better CPU might speed something up, because nothing was slow. The phone never feels hot while using it.
When I try a new phone, I don't see any noticeable difference in speed. Everything loads more or less the same.
A better CPU (even one twice as fast) on a smartphone brings virtually no benefit at this point. Half of "this is pretty fast" is still "pretty fast".
