Has anyone here tested their battery life on their new 4g touch yet? I have fully charged the battery, shut of wifi and bluetooth, and let my iPod play music continuously to see how long the battery will last. This was tested with ear buds in, and volume between 1/4 to 1/2 mark. I was only able to achieve over 20 hours according to the battery meter. This same test on my 2g touch wielded over 40 hours. Does anyone think the battery meter is currently inaccurate? Ive read reports of the meter being inaccurate during recharge.
