hey no prob. One thing to understand about auto-brightness is that say you are in a well lit room, the iphone will actually turn up the brightness based on your max brightness setting on your auto-brightness slider.

You would think the brightness would be dimmed since their is ample light in the room. This may use more battery juice than having it at a constant 10-20% brightness.
