Here are Apple's recommendations for battery conservation:
I can think of two other recommendations:
1. I suggest turning the iPhone off when you are asleep. Otherwise, it wastes power checking your email etc.
2. Be very careful about using location based reminders. These are reminders like "Remind me to ... when I arrive home." These use the location services which place quite a strain on your battery.
Hope this helps.
