John Gruber: “After a few days using this case, my thoughts turn not to the Smart Battery Case itself but instead to my personal desire that Apple had made the 6/6S form factor slightly thicker. Not a lot thicker. Just a little â€” just enough to boost battery life around 15-20 percent or so.”
I don’t have battery life issues with my phone, but I think John nails it. It would be really nice if Apple made a slightly thicker phone. I don’t understand their obsession with thinner and lighter. In fact, my favorite phone design was the iPhone 4 and it must have been the heaviest phone Apple has ever built.
