title: What is the best background color to conserve battery life?
body: <p>I'm developing a web based mobile application and I was thinking about the default background color.</p>
  
  <p>Do different color backgrounds use different amounts of battery life? For the best battery life should I choose black or white or some other color?</p>
  
  <p>I would assume that because there's a back light behind the LCD then white would use the least amount of power because no pixels would have to be turned on, is this assumption correct?</p>
