    White pixels cost 3.5 more energy wise than black pixels and a lot of iOS 7 is a whiter interface. Do you think it will reduce the battery life compared to if they had a darker interface?

    No, the back-light is on 100% of the time regardless of if your screen is 100% black or 100% white.

    That is indeed true for plasma, AMOLED, OLED etc. displays. LCD's (also LED's) have a constant energy consumption independent of the image type (unless you change the brightness).

    As others have said, no LCD backlit displays use the same amount of energy all of the time.
