New Macbook Pro power efficiency and time remaining
> Reducing mA (power draw) rather than increasing mAh (power storage) is the most effective way to increase battery life, which would go a long way to explain manufacturers’ obsession with thinness (which, in electrical terms often directly translates efficiency (i.e., smallness)) in their devices rather than just giving us something that endures.I think it goes the other way; the manufacturers' obsession with thinness (for mostly aesthetic reasons) goes a long way to explain why they're focusing on reducing power draw.It's great that they are reducing power draw, but by making everything thinner (usually translating into decreased power storage), those gains in efficiency are largely cancelled out when it comes to battery life in real-world usage.When creating these things, the designers, engineers, and marketing people obviously have some kind of target battery life in mind, and it seems as though the target is always "about the same battery life as the last generation," whereas there's no end to the number of compromises and engineering efforts that go toward cutting 1 mm off one dimension.And of course, the tech bloggers all go nuts about how thin the newest generation is compared to the last, and people buy computers based on their recommendations.Aren't these things thin enough already, at least for professionals? Why not go for some truly earth-shattering battery life on one of these laptops? Do people really care more about that 1 mm than they do about potentially hours of additional battery life?
