When I know I will be employing the cell phone heavily, I slip into conservation mode employing the following techniques. This really is commonly at a conference or when I know I won't get to charge for a day or two.

This will extend the lifestyle for another couple of hours which helps get through the day!

Turn sound off -If the phone has to make a noise or vibrate, it's making use of battery lifestyle which you desire to conserve. So turn it off.
Do not listen to music. If you will need your cell phone for e-mail or other work purposes, don't deplete the battery just listening to music
Change E-Mail to manual - If you've your iPhone configured to push e-mail down to your cellular phone real time, turn this back to manual to conserve battery living. Do a manual pull of mail when and if you'll need it.
Set Autolock to 1 minute. The longer the screen is turned on, the much more it uses the battery. You'll be able to of course just put into sleep mode immediately soon after use as well.
Turn Bluetooth off should you aren't employing it.
Lessen the brightness as far as it is possible to without compromising your eyesight.
Turn Wi-Fi off if you usually are not making use of it as this is a huge battery drain.
Turn 3G off and use the slower speed GSM settings if mobile data speed is not an issue for you.
Turn off Location Services. You know where the cellular phone is!
At least once a week try to run your battery completely down anyway, then recharge your iPhone to 100%. This will keep your battery in very good condition.
