I go way past lunch as well. I last about two days or one day if my use is very heavy. Every now again I hear of some BlackBerry user or some iPhone user with odd battery life. There is typically some odd setting somewhere that is responsible. I get much the same battery life with the iPhone as I got with the BlackBerry.

What's nice about these small devices are the batteries charge very quickly. The battery has never been an issue. If it is, check a few simple settings. Maybe wifi is set to scan and join every WiFi node it can find or some other silly setting.

I get a good amount of email, have two accounts, listen to audiobooks for about 140 minutes a day plus normal phone, calendar, and note taking and still I could go the full day without losing even half the battery.
