Reading with black background

[ShawnBoucke]

I will be going on a long trip and will be using my iPad to read. Of course I want to battery to last as long as possible. If I have the background be black (I do it by reversing the colors and not in the app). Will it save the battery by doing that or will there not be a noticeable difference?

Good question and I don't think it matters because the backlight which powers the screen is still on. The best way to increase battery life is to turn down the screen brightness.

Where inverting the colors helps is you can turn down the brightness level and still see the text.
