Not this again. Look, it's no secret as to the MBP's battery life. Even on a non-retina MBP, nearly half of the bottom unit is a battery. In the retina MBP over 50% of the unit is a battery.
If the MBP's battery life was so awesome you wouldn't see Macrumors posts in the Macbook section complaining about it.
