My iPhone 4 battery dies too quickly?

No matter what I do it always dies way too quickly. What can I do to fix this? It's about a year old… Is it fixable? Can I get a new battery?

Better to get a new battery because you are saying that's 1 year old one. Otherwise once see your daily usage and better stop using all the day and give rest time for it.

Let me guess, you use it constantly for 4 hours and then are surprised the battery doesn't last forever?
