Why? Obsessing over your battery gauge is not helpful and should only be done if you're doing something that you know is tremendously power-draining. For that matter, I only occasionally glance at my fuel gauge in my car too. If it as at 3/4ths 10 minutes ago I don't need to double-check to make sure it hasn't suddenly hit empty.
