    Is it true that it doesn't matter if you have a dark wallpaper vs a more brighter one, or if you read with a dark background vs a white background, in what concernes to battery life?

    I read somewhere that there is a screen light that is always on, and for what I understood, is consumes the same power always, regardeless of the colors on the screen.

    Your understanding is correct. No additional power is used for any colors.

    White colors actually take more battery power. LED displays are less impacted by this than, say, OLED displays. For example, the reason the Samsung Galaxy Nexus and Nokia Lumia 900 come with such dark color schemes is that white takes a huge amount of power to display on these types of displays.

    Windows Phone 7 even tells you that selecting a white background will significantly reduce battery life.
