Dude wtf are you literally using your phone for 14 hours straight without taking your eyes off the screen? Otherwise I'm convinced you're just playing music for 14 hours.

So, what your saying is that you literally used the phone non stop with the screen on for 12 of the 15 hours. I highly doubt it. That's exactly what my phone said, yet I was using only the iPod to listen to music. In that scenario, you should get 40 hours of usage, not 12.
The Standby time is how long the phone has been on since you unplugged it from a full charge. The usage is how often the CPU is active. Yesterday at 11:30am I was at 2% remaining battery and had 7.5 hours of usage and 8 hours of standby. Today, at 1pm, having used the phone exactly like I did yesterday (minus the 30 minutes of Nike+) yesterday with the replacement, Im at 7 hours on Standby, 3 hours 30 minutes on usage with 49% battery left. And it's 2 hours later right now. If you think your batteries working fine, keep it. You shouldn't have to plug in your phone mid day with the battery that's in this phone, period.

I should get 40 hours just listening to the iPod according to the specs. That's basically all I'm doing. I'm not streaming music here via Pandora or anything else. If my 20 twitter updates is what drained the battery, that's ridiculous.
iPhone 4 battery life is great on iOS 6 for me. Over 2days life. Only takes 45-50mins to charge back upto 100%. Very happy this end
