So I've bee tinkering with my energy preferences in order to get the best battery life I can, I've turned down the brightness to 1, my keyboard back light, to 1 (when I'm watching a movie in a dark room) and I've set it as the 'better battery' option.
But now i'm a bit confused. What's the point in the screensaver if you can set your display to sleep (which i'm sure would save more energy).
Is it just to look pretty?
How does everyone have their notebooks set-up to get the most out of their battery?
Lastly, the 'better battery' option in energy preferences, does this do anything apart from adjust the display/computer sleep? I read that it reduces processor power hence the 'better performance' option.
Cheers and look forward to your replies!

You can set your system to require a password when waking from sleep or screen saver, but not from only the display sleeping. As far as energy, having the display sleep (turned off) would probably save more, but I like the added security of requiring a password. However, to save energy, the screen saver I use is BlackenedPixels, so the display is turned completely black, saving energy.
 
Thanks for the reply,
so I guess the best thing to do is, set the screensaver for 1 minute with password and display sleep for either 1 or 2 mins...
Also I was under the impression that LCD screens use the same power, whether displaying black or any other colour...

As far as I understand, a brighter image or an image with more whites than a darker image or an image with more blacks, consumes more energy, but I can't get into the technical details right now, my brain is in dire need of sleep, just my motor skills are too defunct to actually heave my body onto the bed, and I'm not even drunk.
