One definite problem is the Setting Time Zone function in Locations (under system services). It never turns off location searching so it drains the battery. Turning off the Time Zone feature eliminates that particular problem.
Just let me turn off my damn 3G! It destroys my battery life.
You can......
Settings -> General -> Network -> "Cellular Data". When you shut that off and you're not connected to wifi, you'll see that the 3G symbol is gone.![]()
If you do that you'll remain connected to the 3G network which will use more power than the 2G network.
The "Cellular Data" toggle does exactly what it says - it disables sending and receiving data over any cellular network (2G or 3G).

make sure you turn on off location services for a bunch of stuff though.
Turn off iCloud Contact syncing. My iPhone 4 battery was dying from 100% thrice daily. I used iPhone Configuration Utility and pulled the console logs, and it's sending out multiple error reports every two or three seconds regarding iCloud and contact sync services. Turned that off, and all of the sudden my iPhone held a charge for two days again.
