Right, by this point high end phones should be much more powerful, with much more memory and battery life and more special features or similar. But the delta between high and low is mostly GPU and to some extent CPU speed and screen resolution.

For example, I'd expect by now that 64GB would be the default for mid and high end phones with 128GB and 256GB as options. Instead we're still seeing "high-end" phones at 16-32GB.
