In terms of battery life and everything? Does it make a big difference to turn off auto-brightness and leave it on 20-30% or so? Or not worth it?
I use auto brightness and so far my battery life has been great. I prefer the auto brightness because then I don't have to manually dim it if I'm in a dark environment.
Mmy top battery consumption is ALWAYS display. Once you root, you can dim below the stock minimum of 10% brightness. i run all day at the lowest possible setting.
I use an app (free in market) called fastbright. Its a one-touch widget type app (strange, it's not a widget, but the app is a one-touch fuction). Anyhow, you tap the app button and it immidiately adjusts the screen brightness to whatever you have defined as a preset brightness - Very handy for outside with sun.
Auto brightness has given me the best results.. although its not too drastic of a difference.

Because I have clocked my Droid, I am a little more sensitive to the power drain on my Droid. I have finally set on leaving my backlight set on 10% and have disabled auto brightness. This is normally too low in most situations, but I have resolved that with a wonderful app called Screebl. Basically you set the angles at which it will boost the backlight to 40% (or whatever you set) and set the screen timeout to 15 seconds. If you are within those angles (i.e. holding your phone in your hand) it will keep the backlighting on. Lay it down, or even propped up at the correct angle and don't move for 2 minutes and it shuts down. Out of the angle, 15 seconds. It's the best of both worlds and you NEVER have to worry about the screen going dark if you are actually using it. It has made a huge difference for me. I really cannot live without it now.
So, let me get this straight... you run with the brightness turned ALL THE WAY dowm and autobrightness enabled and this gives you good battery performance? Plus, you don't ever have to mess with the settings or use any apps?
I used autobright for a little while and it just switched dark / bright / dark / bright almost constantly, it was annoying. Was I doing something wrong?
