If you think your battery may have issues, you can test it with this test used by Genius Bar techs.
Write down your usage and standby time, press the sleep/wake button (or lock button, as some call it) to put the device to sleep, and set the device down for five minutes. When you come back, take note of the change in time. If your device is sleeping properly, then the Standby time should have increased by five minutes and your Usage time by <1 minute . If your Usage time rises by more than one minute, you have a drain problem. Something is keeping your device from sleeping properly, significantly shortening the time it will last.
If you still have issues, you may want to take it to an Apple Store and let them look at it. Everything has lemons. Even iPhones!
