my eyes are getting bleary
i turned down the display brightness by just a bit and i think
its making quite significant savings on battery life
Nowadays, I just set it to auto brightness, because the default
battery life is just awesome. If need be, I'll just use the tasker
app to run individual apps with custom brightnesses. eg, movie
player run at maximum brightness, upon exit, minimal
brightness.
I recommend you get a widget for brightness profiles.
