They do make portable batteries that charge your phone also-ebay.

Turn the brightness down or put it on Airplane mode.

Well some iPhones have been known to have battery drain issues but if you do things like turn down brightness and make sure when you are done with an app double tap the home button and close it out by holding the your finger on the picture of the app and hitting the red minus button plus some apps use more battery than others and if you have it constantly searching for a signal like Wi-Fi that will drain the battery
