iPhone Battery Life Complaints

If your iPhone battery life is poor, your phone is broken. Bring it in the Apple for an exchange. My iPhone will literally go for three days without having to re-charge it. I have my screen brightness set all the way down, I can report the best battery life of any cellphone I have ever owned. I have wifi on all the time. I have bluetooth off. I use all the features all the time, and can report no negatives on any aspect of the phone.
