I have UD2.0 installed right now and I came from Cyanogenmod 6.1RC3. Both of these ROMs have the automatic backlight settings and I think it would be very useful for better battery life but the problem is that I don't understand what most of these settings mean. I have searched the internet for a guide/best settings, but I cannot seem to find anything for the OG Droid. I was wondering if anyone could explain what these settings mean or possibly point me in the right direction.
