Guys with good battery usage, when your battery is near 0% how much time was your display on?
My display taked around 65% of the power consumption, and usually when it is on around 2.5 hours my battery dies. So it seems that even if I optimize all other things to reduce battery consumtion, when my display will reach ~4 hours the battery will die.
(My math may be wrong, I assume that my battery can provide power of X (linear consumption), and if my display takes 65% of it for 2.5 hours, then
0.65*X=2.5 ==> if all battery power went to display it would be X=2.5/0.65=3.8 hours).
And my brightness is set alsmost all the way to 0.
Just wonder how much display time you get...
