I agree the iPhone's battery life is not good. But people who are really bothered by this and can't find a solution are not trying.

There are many external battery packs (also called battery extenders) for the iPhone. They are typically 1800 mAH (compared to the iPhone internal battery roughly 1100 mAH) and cost $40-50. These will usually 2X to 3X your iPhone's "battery life". Juice is one brand.
