The iPhone will typically go around 3 days between battery charges. This time may go up or down depending on how much you use your iPhone.
Heavy users may have to recharge every day.
You'll need a power adapter to charge your iPhone away from your computer. Normally this is done via USB but you're not always going to be around your computer.
It's a good idea to buy one or two chargers to keep you running.
