Battery life-weight trade-off
Why do the manufacturers feel compelled to make the choice for us? Couldn't they sell the phone with the option of a lighter battery of a heavier one for more hours? Or with two or even three battery pods, so you could change configuration whenever you wanted to? (Like swapping between a CD drive and an extra battery in IBM ThinkPads, some years ago).
Of course that's only possible if the battery is user-installable.
