My 8 Plus feels like it must weigh at least 5-6 times more than my 5s. The weight combined with the size makes it a much more awkward mobile for me in some ways. I like my 8 Plus, but I cannot figure out why it should be this much heavier. Is it the "glass" back on it that adds this much weight to it? I do not have a scale sensitive enough to weigh the 8 Plus. Anyone know how much it weighs?
