How much of a battery killer is the display

    I left my MBP turned on and dimmed the screen down fully, but forgot to leave it plugged in. I came back 5 hours later, and was amazed to find the MBP was still on with 24% battery left!

    Is the screen a huge killer of battery life? My MBP was saying it could go on for another 2 hours and 5 minutes with 24% battery with the screen fully dimmed down.

    That's 7 hours in total without the screen being on, quite impressive!

    Another thing, I've noticed that my SR MBP charges a LOT quicker than my old 2nd gen MBP did. It can go from 0% to 100% in about an hour and 40 minutes, where my 2nd gen would take 2 and a half hours at least. Anyone else noticed an improvement in battery charging times?

    I can't comment on the last bit, but yes the screen is a huge power sapper. As is a constantly writing hard drive and a spinning optical drive, FWIW. :)
