My old 8gb iPhone had a nice battery life (received in Sep 07, sold this month). Like at least up to 5-6 hours of varied activities usage. But the new iPhone 16gb I just bought after being disappointed with the 3G announcement? My first full run with it and it survived 9 hr and 15 min of usage with 1 day and 16 hrs standby. Usage was comprised of email reading, web surfing, 2 or 3 texts, calendar adding/editing/checking, phone, notepad, some maps, weather, and lots of iPod. Don't know what they did to the batteries in these news one.....But this phone's battery life is truly epic. It only has one stuck 'red' pixel. I'm living with it though.
