Just bought an Ipod touch 2 g 16G two day ago. Wandering if the battery life is what it should be. I tested it under worst case scenario: Backlight on approximately 50% brightness entire time WiFi enabled and connected Driving 24 ohm 30 mm headphones approximately 50% volume I started it playing music & stopwatch (app) & left it alone. I got just over 4 hours and 35 min before it completely died. With the first low battery warning (20%) after 3:38. Is that within reason or is my battery defective? One other question too. Why buy an Ipod? I have a cell phone and do not want to pay for the unlimited data plain but If I was to buy an Iphone outright with no cell service associated with it. Wouldn't it basically be an Ipod with the addition of a camera? Is there any advantage to having an Ipod over an Iphone?
