The Worst Feeling Ever? No Battery Power

Lately it seems like I'm forever trying to make sure my iPhone isn't dying. I have to be sure I have enough battery power to get me through my idle browsing when I'm sitting at home not watching my dad's game shows. I have Facebooking to do, Pinterest, Scrabble, Draw Something, and many other very important things to do, I'm sure? In response to this, my iPhone decides to hemorrhage battery power like it's going out of style.

What gives, iPhone? Why the crappy battery life? What can I do to recharge you, because the extra charger I carry around at all times doesn't seem to be doing the trick. I'm at a loss here, iPhone. How can this be helped?
