Does iPhone brightness affect battery life?

My auto brightness is turned off, 50 or 60 percents...

Yes. It does.

Of course it does. LCD light intensity. I've noticed that more on my iPod classic. It'll start dying on me and then I'll turn down the brightness and all of a sudden the battery bar color will go from red to green. So it should be the same for an iPhone. Not as dramatic, but internally I'm sure it does something.

It definately has to be on the list of the things that suck the most juice. The screen is why when you plug an iPad in through USB it says not charging. I hate anything auto so I have my brightness set as low as I can stand where it balances looking good and being dark. I turn off Auto.

Keep it around 60% and it'll last you a bit longer. Any phone or device with a screen on maximum brightness is obviously pumping in a lot more juice to the display and draining the battery quicker than one with a lower brightness level. Use a higher brightness only when you're in the sunlight or something and you can't read what's showing up on the phone.

Seriously?
