Screen Brightness and Battery Life Question

[Terry_Wr1st]

Is it ideal to leave Screen Brightness at 100%? What would be the difference in battery life compared to default settings (50%)?

Well the battery will run twice as fast as it would with 50%. My Brightness is at 40%, lol hats bright enough for me :)

haha 40% im on 25% thats enough for me, and a partial charge around 1/2 hour seems to last for ages now...
