lol I think he meant that he returned the phone and got a replacement, or a different phone.
If you want to be very specific about what is causing your drain, then get BetterBatteryStats. If you're rooted, you will see under Alarms the specific service that is causing wakelocks. Most likely it is Google Play Services. The battery drain sucks. Turn off Location reporting in Google Settings (and also turn off remote location under Android Device Manager). Pretty sure that doing both is what helped me. But I went back because I am trying to see if Google Now is worth it. You should aim for 1% per hour idle drain and ~95% deep sleep
