One of the really interesting things about batteries is their draw rate.
If you increase capacity, you usually are changing the chemical make-up of the battery such that you decrease the draw rate (you have less power to play with... but more overall so it lasts longer).
All those big screens suck power like no-one's business. Couple it with hungry CPUs and to get the draw rate right, you have to change the chemical composition such that the capacity is reduced, or the number of recharge cycles is reduced.
Batteries are interesting things. And no matter which way you look at it you're making a compromise somewhere.
