Samsung Galaxy S5 Mini is not that far from your requirements. I'm very happy with S4 Mini, S5 Mini wasn't that much of an improvement to make me upgrade. Physical button, replaceable battery, SD cars slot, all must-have features in my opinion but which are getting less and less common. Anyway, this size of phone is maximum I can handle with one hand. It's easy to unlock on the bottom, pull notification on the top and reach any corner of screen if needed. With larger phones I either have to use both hands, or "scroll" phone if I need other part of screen.
