Ditching the glass back and reducing the thickness of the glass panel on the front has affected the design of the metal band around the edge of the iPhone. It is now chamfered and while that looks pretty, we've already noticed that on the black model the edge has started to wear, revealing the shiny silver aluminium metal underneath the "slate" coloured coating and, indeed, we've witnessed it on two separate models, ruling out a fluke manufacturing error.
These small scuffs will catch the light and make the phone look visibly worn. We suspect that it won't be as noticeable on the white model because the metal edging is silver, so that's worth bearing in mind when you come to order your colour choice.
Good to know, thanks. No wear on the chamfered edges at all?
