turn the phone off

You'll drastically extend the life of your battery by powering the phone down when it's not in use. I get a week out of my iphone by carrying an external battery pack, which is the size of the phone. (You plug it into a usb port at home to charge the pack, and then it can re-charge the phone once. It also has a solar panel, but I don't generally need to use that.)
I check a few web pages each day, for weather and such. Email progress reports/float plan changes to the home office. Talk to my wife and daughter most nights, and otherwise just keep the phone off. If I leave the phone on, it runs through the full charge in about a day and a half. If I simply turn it off when not in use it lasts 3-4 days on a single charge.
