Ok, so I have spent the last few days tweaking the auto brightness settings.
My goal was to have the screen at the dimmest level at just about all lighting conditions, and to not have to strain to see things on the screen. In doing so I also altered settings to the sensor filter and scan timing to make it a small bit snapper. I needed to do this because sometimes I unlocked the phone to a screen so dark I could not tell it was on, and it took too long to adjust. Now it is pretty snappy. I took all my samples from many light situations, however there are situations where you may be directly under a light and at a angle where you have glare. I made no compensation for glare, and find no need to as it's very rare for me.
My goals were power savings and usability. I don't care about colors. if I want better color and I'm going to be using in a dark room I'll turn auto off for a bit. But I honestly don't find them that bad and like a dim screen in bed at night..

This is good stuff. I've never been able to tolerate auto-brightness, but I may give it another go. Thanks for sharing your tweaks.

No problem. I'm not into coding at all. So when i find something that's on my level to modify i like to give a little back to the community.. Feel free everyone to post tweaks if you find some.. im still going to tweak the high levels, but have not had sunny days to get some good tests

I second this. I've been on these settings for a few days now, and I haven't had to touch the manual settings. I think it's safe to say I'm an auto brightness guy now.
I still use manual when I'm indoors like in school where I just leave it all the way down because lighting is consistent, but I leave auto on the rest of the time.

Neh4pres, at the top of your screen shots it shows:
Sensor (filtered/raw): 6/5

After applying your settings, my phone shows -1/-1, disabled, -1 for those same settings, but I don't see any way to change them. Is there something I'm missing?
That's a great setting for autobrightness. But i think its not good for battery life.. too many levels will cause the system works hard for changing the display. Im currently on 7 levels, it gives me a great battery life. I'll try this and report, maybe my thought was wrong...

Those are not settings, those are a read out of values of the sensor. What you need to adjust is the grey boxes... And your readings of -1 simply means your auto brightness is turned off.

You could have a thousand levels and it would not make a difference.
What would make a miniscule difference is sampling rate.. But you turn that up to high and your going to start feeling very impatient when light around you changes and your screen takes forever to reflect the changes.
And you won't be saving much of anything by doing do.
Example:
Walk indoors from the bright outdoors, your screen takes 10 seconds to turn down from max brightness. You just wasted more battery with your screen in those 10 seconds than you were trying to save by turning sampling time up.
Our screen is our biggest battery killer
Sent from my SCH-I500 using xda premium
I still get about two days of life on the stock battery with these settings. Like neh4pres said, the screen is the real killer. There are also a lot of other tips and tricks out there to get the most out of battery life. In the end, I can't imagine my sampling rate is making any significant difference, and I love watching the screen quickly and smoothly ramp up when I step outside.
I just tried these values....its too dark for me but I like the consistency. I would like to try some slightly brighter values but I am not sure how this works. Can anyone give me some suggestions ?

At the top of the screen where you start the settings it shows what light level your on at that second. if it's to dark at that moment adjust the corresponding level and hit apply to see the difference..

Ok using the values from the OP, currently I am on Screen 11 and its a little too dim for me. What value do I change now? If I unlock screen its on #9 and dim as well..
It's not that bad really just after unlocking there is a heavy blue/purplish tint which goes away in few seconds as the screen brightens but if I could keep it like this only slightly brighter that would work. I don't really know which value I'm supposed to change..
In the meantime I found a nice compromise, I'm using:
Window length: 5sec
Reset threshold 400Lux
Sample interval 2sec
Screen Dim Level @ 20(default)
With the default levels and it seems to be working well so far. I'll know later tonight when I'm listening to beats in the dark.

Screen dim level set to 1. Then it's the values that are different in the pictures, the middle ones. Those are the brightness values. The first 2 numbers on the left are the light levels that would enable that level.

Please add the option of modifying auto-brightness levels, like CM 6.1. I suppose that it would require a kernel modification + an app to do this through gui.
Thanks.
What can CM do? I've been thinking it would be nice to be able to modify the min and max, and maybe the curve.

It allows one to arbitrarily edit a table of sensor output vs brightness/button brightness.
It's really nifty.
CM6.1 reports these sensor values:
10, 160, 225, 320, 640, 1280, 2600, 10240
10-160 is in dimly lit indoors, 320-640-1280, in moderately to brightly lit indoors, and the rest is outside.
So I set those to brightness something like 50,60,70,80, 110, 140, 180, 255. A it was perfect to my eye. Not too bright, not too dim.
Didn't ever have to mess with brightness after that.
I'd really like to hear from developers like Netarchy and King, as well as from regular users - if they would like that option.
I would love to see this.
I always feel the auto-sensor tends to be too bright, and never adjusts the screen low enough inside.

That's exactly what I think. Plus, the brightness is not at maximum in direct sunlight (although that might be a safety feature).
Mine always send to bright, or it won't get bright when I go into a bright area until I sleep and wake it. :|

The lack of adjustments to the auto brightness values is extremely annoying. Even my old Windows mobile 6 phones had this ability.

There was an application for WM I used to use on my Mogul, cant remember what it was called but it allowed you to calibrate the auto brightness levels. Anyone know what I'm talking about, or if there's an Android version?
This can be done with Tasker in the Market. Its a powerful app and there was a thread a while back about this exact thing. I don't remember what it was called, but I posted in it, so you could browse my posts from a month or so ago.
Hey... This thing makes phone calls too!
I'd like to start this bounty thread with a $50 offering.
The requirement is to hack official HTC Sense roms to be able to set levels of brightness which autobrightness uses.
It could be done via an app, or a file edit, or the way cm6.1 does it. And it should be supported for the future OTA releases.
The only true requirement is that I never have to worry about setting brightness again, after I tweak the brightness values to my own eyes.
(technical: autobrightness adjusts the brightness of the lcd by reading the light level sensor. CM6 allows one to edit the table of brightness vs. light sensor. Sense might implement the autobrightness differently. Regardless of the implementation, the default values of brightness, that autobrightness uses, should be adjustable.)
In for $10

I would like this issue to be fixed as well, but am curious to know how much a table would actually help. It seems that it may not be as bright outside as it is inside sometimes, but the sun reflects light a lot worse than a ton of florescent or artificial light does. When i am inside and all the lights are on, i can still read my phone with the brightness at 15%. But when its cloudy outside it needs to be at 100% or its hard to read from a direct angle. I would almost prefer to leave my brightness at 15% all the time, and then use a hardware switch like hitting both volume rockers together to toggle 100% and 15% to change the brightness.
It would be awesome if the evo used the front facing camera to detect the sky behind you or even use the better light senser in a camera, to detect and adjust the brightness. Probably not great for battery.

How does changing that setting qualify for manually adjusting autobrightness values?
Here's how cm6 does it. It creates a table:
Light Sensor level - Brightness
10 - 50
160 - 60
225 - 70
320 - 80
640 - 110
1280 - 140
2600 - 180
infinity - 255(max)
The autobrightness reads the light sensor level and then sets the brightness to the corresponding brightness value.

Auto-brightness is hopeless anyway, turn it off, as well as the setting Bigmile mentioned. Then, to make quick on-the-fly adjustments to your Note's brightness long press in the notifications area and slide left and right till you get the brightness you want. Much better way IMO.

The only time I've seen this happen since I've gotten the device is when the battery dropped below 5%, and it automatically adjusted the brightness to seemingly the lowest it could go, and stuck until I charged it to full again.
I blame it on Samsung's stockware.
maybe this is why i couldnt get the phone to look as bright as my note 2. i was using the browser and cnn.com to compare.. my note 2 screen was brighter with both phones brightness on max.

Just throwing this out there...the screen does dim about 10 seconds before the screen times out and turns off...even if you have automatic brightness disabled.
Let's say you have a 1 minute timeout:
Screen on
50 seconds later screen dims
10 seconds later screen turns off
Just putting that out there in case - it is confusing to some.

I'm sure it has to do with preventing burn in. You probably already know this, but in the right conditions, the Auto brightness setting can get over 30% brighter than manually maxing the slider. Hopefully, it's something that can be unlocked at some point.

I got my Galaxy S4 yesterday and noticed even after i turned auto brightness off, Set my screen to dynamic, the screen still changes brightness levels when entering the Chrome web browser (gets dimmer), playing some video games (screen get brighter) and other various tasks.
I am not a noob, I've gone through the phones settings for each app and cannot find a fix, do you guys notice your phones doing the same thing?? I might be a slight change in brightness level but non the less i like my screen extremely bright this is just my preference.
Any thoughts, ideas, tweaks or feedback on how to resolve this issue??

I don;t know if this helps or not....i notice the same thing earlier.....what i did was go to Settings--> Display, uncheck Auto Adjust ScreenTone
at least that is what worked for me
Maybe the power saving mode is manipulating it?

Its the power saving option. Its the same in s3. Go to powrr saving settjngs and uncheck the auto dim or auto brightness or something like that. It happens when power saving is on. I cant remember the exact optin coz im using custom rom on my s3.

This happened in the S4s I used in the store as well. Manual brightness, and auto screen adjust disabled, power save off. Opening certain apps like chrome and the stock browser causes the screen to dim a bit. Nothing I found prevented this behavior. It's annoying since I already find the screen to be a bit dim.

Notice this as well, super annoying. I've disabled power saving, auto screen adjust, etc. and even non-dynamic modes do it.
Hopefully this gets fixed by kernel mods in the future
Same problem, even with brightness max with auto off, decent charge, and off power saver. Very annoying

Its built into the Snapdragon, its called BRITE and seems works independantly of the auto screen tuning that the S4 has. The HTC One has it and its much more intrusive. I wrote a long winded post about it in the HTC One forums. You have to wait for devs to come out with kernels to disable it, much like they did for the Tegra 3
The HTC screen is bright enough that it doesn't matter. Samsung phones need to be at max brightness to be any good.

Just an FYI, if you put the screen on auto brightness, it reaches a higher maximum brightness outdoors as apposed to the slider. Samsung did this to keep the screen from overheating when set to max all the time.
I want full brightness indoors too.

I see. If you have the slider on max all the time, i think the screen will just dim eventually because of heat. Might want to stay away from the S4 then cus you might have screen problems down the line :/
If you havent go to settings display screen mode and use something other than adapt display. No more adjusting.
