Effect of Background Color on Battery Life in Android App I am studying about the effect of different parameters of Android app on Power Consumption and tips for optimizing them . I came across this 
paper which states that ligh background color consumes less power than dark bg color.
I wonder whether We can apply the same logic for apps. When I measured the power consumed by changing the back ground color of a mock Android App , I couldn't notice any change .
Is the change too small to notice or it didn't occur at all?
It would also vary with the type of screen, blacks on AMOLED screens do not turn on the cell, so there is no power drain. It's a bit more complicated than the paper suggests. Really the brightness will have far more effect than a colour, unless you are going all white or all black, and even then the screen type and the software rendering will have a huge impact. –  RossC Oct 22 '14 at 10:52
