If you wanna automate your display brightness Then download the App Twilight which automatically adjusts the screen brightness according to the local timings.
Dump Unnecessary Widgets
Just Because they're sitting on your homescreen , seemingly inactive , Doesn't mean that they dont consume power . This goes for all widgets that poll status updates in the background, as well as those sitting rite their at your home screen (But don't dump everything, as part of what makes Android great are the home screen customizations; just remove the ones you don't use.)
