I have seen some touch screen readers that have a gray on black background scheme that helps to reduce the power consumption and increase battery life. But those settings do not really exist on the Nook Color that I can find. What setting is more efficient, and does it save any significant amount of battery life? Is there any way to do a custom color set?
Generally, the best way to save battery on a NOOK Color (or any device) is to:
- Lower the brightness
- Turn off Wifi and Bluetooth unless necessary
These two steps can more than double your battery life on some devices.
