I have always kept my phone on dim setting because my phone has crappy battery life, and its seems to last longer sometimes, but shorter other. With my Nook, its the same, but I also make the book pages where the words are white and the pages are dark gray, hoping thatll help. With my laptop, there actually is a setting called "Battery Saving" that dims the brightness. I know it works on my laptop, but does it actually save my battery on my phone and nook? Thanks in advance.
