> Part of me wishes it is for battery life, yet sadly in many area's like this when we gain battery life we find that offset with a smaller battery and the marketing of how it is now lighter prevails. The iPhone has gotten thicker and heavier year-over-year for every year since the iPhone 6, mainly due to monotonically-increasing battery capacity, and the new MacBook Pros are also thicker, heavier and with a bigger battery than the outgoing ones too. I'm not sure where this "they always make it thinner and cut battery capacity!" meme comes from.
