Push notifications probably aren't the issue. Perhaps you are using an app that uses GPS a lot? Or maybe you have the screen set to sleep after a longer period of time than before. It is hard to guess at what may be wrong without seeing it.
Gps apps will suck a battery dry in hours, but amy app that "uses your location" activates the GPS. Most turn it off after getting a fix, but if you see the little arrow at the top right of the screen, your GPS is on.
Chris Breen wrote a helpful article about troubleshooting battery issues with his new iPhone 4S.

Two things I learned from the article were how to view crash reports on the phone and how to monitor CPU usage with the System Activity Monitor app. http://itunes.apple.com/us/app/system-activity-monitor/id306192663?mt=8
Ultimately he reset his phone and he thinks maybe a corrupt contacts database was to blame. I had some iCloud and voicemail issues that were fixed when I reset my iPhone 4S and refrained from restoring the backup from my iPhone 3GS. It was a pain organizing all my home screens and reconfigurng apps but it helped.
