Keep GPS, WIFI and Bluetooth off until you need to use them.
Under sounds and display make sure you have 'automatically detect brightness' selected and power saving mode checked.
I follow these simple steps, and my battery lasts for a good 15 hours, and I'm always on it.
Good luck, I'm sure other people have little tips and tricks they use.

Having the GPS on won't hurt battery life, because it is only active when an app is using it. The best battery life you will get will come from rooting and debloating, or running a custom ROM. I get almost two days of battery running my setup

If you have WiFi at home you want to use that instead of 3G data. I use Auto Wifi Toggle to monitor my wifi connection and turn it on/off. I also suggest rooting your phone and removing the crap Verizon places on your phone. I run a custom rom and kernel that has already been optimized to save battery.

I understand rooting can be a bit scary and if you're not comfortable with it then by all means don't do it, but the forums are a great resource and we have tons of people here who can help you through the process if and/or when you're ready to root.
As for battery life, there's not TOO much you can do without being rooted other than tweak some settings. Don't listen to suggestions telling you to keep GPS and WiFi off when you're not using them -- we've discovered over time that it has essentially zero effect on battery life. Like Kevin said, GPS remains idle when it's not being used and has zero negligible effect on battery performance. If you don't have screen brightness set to auto, I would also recommend doing that as well.

@jaybro, how do you use your phone on a normal day? A lot of texting or talking? Games? I do some texting, a lot of web browsing, a couple phone calls, and end up with 60+ % at bedtime. I have GPS and wi-fi on at all time. Screen brightness set to auto.
How is the coverage in your area? Do you get a strong signal in all parts of your house/work? I've seen batteries go dead in 2-3 hours with the phone just sitting there looking for a signal.

the biggest hogs of battery life since i've had my FASN8 have been the display, and i keep at the lowest manual setting which is plenty bright enough for indoors, and the radio itself. when i'm at home or work the vzw signal is poor so the phone sucks a lot of juice trying to find a better signal."One Really Really Deep Thought" by Ytaay...

my battery lasts about 4 hours max... rooted, tons of texting and facebook.hardly make calls. gps on and brightness on auto. also i live in houston so i have pleanty signal. i did notice my signal jumps alot when im texting though. even when it switches back and forth between 1x and 3g after a text message.
also does noLED drain the battery?

Yes, noLED will drain the battery, but only when it is displaying notifications (since it is keeping the screen turned on). You can change the settings so that the screen will turn off after a specified amount of time, which will help.

What are some typical drainage rates you are seeing? My phone drops about 20% in a 10 hour day without making calls. (2%/hour) That is with everything on except bluetooth. BT will drop it a couple percent more in a day. My phone is basically stock but rooted. I haven't noticed anything different in battery usage through all 3 software revisions. Occasionally I will notice an unusual drop in battery but I think I found that Shopsavy or or weatherbug was looking for a gps location while it was tucked in my desk. When this happens, I would see a sudden drop of 10-20% in an hour or so.
I also get about 25% time without a tower signal which probably hurts my battery.

Charge your phone for 5 minutes or so then take it off the charger.
Let it sit for an hour or two WITHOUT USING IT or waking the screen.
Go to settings>>about phone>>battery use and you will see the problem at the top of the list. It should most likely be "cell standby" if it is working correctly.
