Logically you should be getting roughly twice the battery life compared to other phones with the same or very similar specs. It's only 3300mah. Sure if you are heavy on it, it's going to wear down faster than those who are "average" users. So I guess the questions is whether or not you think you have a defective unit? If so, take it back to VZW and explain to them your situation and hope for the best. My phone lasts all day with no issues, but I'm not a heavy user and I'm not normally in a 4G area and wifi is normally turned off. Try a day of light usage and see how far it takes you.
