Seems since I went to 50% with auto brightness off battery life is going quick. 74% with 1 hour 15 minutes usage and 10 hours standby
 
Quote from iPhone Manual:

"Screen brightness affects battery life. Dim the screen to extend the time before you
need to recharge iPhone, or use Auto-Brightness.
Adjust the screen brightness: Choose Brightness and drag the slider.
Set whether iPhone adjusts screen brightness automatically: Choose Brightness
and turn Auto-Brightness on or off. If Auto-Brightness is on, iPhone adjusts the screen
brightness for current light conditions using the built-in ambient light sensor."
 
Personally, I turn off auto-brightness. Not to save the battery, it just bugs me when the screen goes dim or bright on its own. I prefer a single setting.
 
My current settings are

50-55% brightness

Auto brightness off

30% battery life

3 hours, 56 minutes usage

1 day, 10 hours standby

is this normal? would i be getting more battery life if the auto brightness was on?

I keep my brightness down to about 25-35%. I am jailbroken and have an app that turns the quicklaunch volume control into a brightness control so if I'm outside and need to increase the brightness it is very quick and easy to do so. I bet if you were to drop your brightness down you would get much better battery life.
 
chances are yes you would. The amount of power it takes for auto brightness to run is next to nothing.
If the sensor is what I believe it is then it is nothing more than a resistor that decrease resistant with light. Those were used in some kids toys in the 60's so clearly they have to of gotten cheaper since then.
That being side Apple Auto brightness controls are pretty poor compared to others and even the others are not that good.

Well this is mine..

What are you doing during your 3 hours and 56 minutes? A lot of streaming and games? Or is that just normal usage?
