I found the display way too bright. You can reduce it by the command:
sudo sh -c "echo nnn > /sys/class/backlight/rpi_backlight/brightness"
where nnn is a number from 1 to 255. I set mine down to 80, which is much better for my eyes and reduced power draw from 1.2 A to .9 A.

Please consider adding other handy tips to this thread.

The wiki in GitHub might be a good place for tips like this, if Ashhar wanted to activate the wiki...
