Due to the poor battery life on the iPhone I have been testing various settings and hardware to see what will work well for my needs.
Brightness
The iPhone by default uses an Auto-Brightness. I am not sure how it works but the iPhone is bright enough to light a movie theater with the default settings. Turn it off in your Settings > Brightness area of your iPhone. Also setting down the brightness to the mini increased my battery life by about an hour.
Car Charger
If you have a car I suggest you purchase the Car Charger for the iPhone. You can plug your iPhone in to charger and your battery will charge as you drive.
Solar Panel Charger
I am outside usually a few hours a day. A good way to charge the iPhone while outside is to use a Solar Panel Charger. The little panel costs less then $30 and keeps your iPhone battery charging while you have fun in the sun.
Emergency Charger
If you need to extend the battery life in an emergency you can get a USB remote charger for your iPhone. I like that you can slip in some AA batteries (available almost everywhere in the world) and have your phone back online. If your a power user then this little device might be a life saver some day.
Hand-Crank Charger
The eco-friendly alternative to charge your iPhone would be to use a USB hand-crank charger. You would need to crank it for several minutes and then could charge your phone. I would personally prefer the Solar Panel charger but this one might be good if it is raining.
What have you found helps with extending your iPhone battery life?

Turning down the brightness does work and is a good idea. I had to do the same with projection TV to help preserve the bulb so if you look around, there are plenty of gadgets where doing simple thing like this can extend their life.

I use the brightness tip too. I always keep my brightness on the lowest setting all the time.
I do the same thing with my laptop when it isn’t plugged in.

Also be sure to turn off any radios that you don’t need: 3G, Wi-Fi, and Bluetooth can be big battery hogs.
