a 6 hour active 3g connection is equivalent of 6 hours of talk time (over 3g too)

do you know many phones that can last much longer than 6 hours talk time on 3g?

People do not tell you to disable these functions but to use them when needed.

I think you should return your phone as you were clearly looking for something that does not exist. Not bashing you, just saying it as it looks.

Sorry
