I hate dark screens as well, but the problem is that the more brightness you have, the more battery it eats
 
I have it on about 70% just to save a little bit of battery but doesnt take to much of the screen brightness away... What is the deal with Auto brightness? i dont really understand it?

Auto-Brightness is a patented technology in which a light sensor is used to determine how much light is around you.
This sensor then tells the screen what to adjust it's brightness to, according to the lighting conditions.

Correction: For example, in a dark room, auto-brightness would set the back-light lower, to compensate the dark conditions.
(Thanks Phil)

Hope this explains it a bit better for you.

no, it sets it lower so as it not blind/hurt your eyes
in bright conditions it brightens the screen, making it easier to read
from apple website:
Ambient light sensor.
The ambient light sensor in iPhone automatically brightens the display when you’re in sunlight or a bright room and dims it in darker places.
 
I keep my 1st gen iPhone at 60%. This is plenty bright and gets me through a full shift at work:)
 
If the auto brightness works than you shouldn't see a change in brightness. If it didn't work, the display would seen very dim out in bright sunlight, and seem to glare at you way too brightly inside a dark room at night. At least that's how it seemed to be with previous palmtops I've used without this feature.

I leave auto-bright on with the slider set at about 30%... enough to make the display readable without wasting a lot of battery life. I paid for an information appliance, not a fashionable flashlight.
 
Thanks guys!

I thought it would be that :p Just never noticed any difference
 
I keep auto bright off and brightness turned all the way up. I hate a dark screen.

The times I've put the brightness all the way up, it nearly blinded me. You can light up an entire dark room with the brightness fully up. I don't even want to think what your battery life is like if you are playing a game or browsing the internet (ie screen is continually lit up for 30 or so minutes).

I have my brightness on about 10%. I can read it fine and I don't have to worry about using the display too much kiling the batter.

For all the talk about how Push or location services or 3G kills battery, having your brightness above 50% dwarfs all those in the battery drain department if you use your phone at all.

Thanks for the reminder. I wasn't thinking about it when I had mine about 85%. I just moved it down to about 50%, and I'm already used to it. I haven't complained about battery drain, but every little bit helps. :)
 
i don't think anyone answered this, but the way to tell if auto-brightness works is by go into your brightness settings and toggle it between off and on, you will see the screen brightness change.

try it in a dark room and if you turn it off it will get a little brighter.
 
I switch

When I am at work, I tend to raise it as high as possible

When I go out socially, I lower it so if I pull it out, it isn't the brightest thing in the entire bar
 
I keep it at 40% with auto brightness on and haven't had to touch it since launch day. Its visible in full sunlight and not too bright in a dark room.
