I just got an XS here in Germany to replace my old 6. Other than the Face ID (which is taking some getting used to), it’s not really all that different from my 6. I’m sure the camera is better but I haven’t noticed any significant improvements yet. The battery life is better, but that’s to be expected with a newer phone versus one that was pushing five years old. And the new ones don’t even look too different from the X models. It seems there haven’t been any game changers for quite some time.
