This is a two part question. What screen brightness do you usually leave your phone at? I leave mine on what seems to be 0 (see next paragraph for explanation) and my screen still always uses around 60-70% of my battery. I don't understand how it can use that much without the backlight on.
Next question - When adjusting the screen brightness and the slider is all the way to the left is that 0? I'm asking because every widget out there when set to 0 is a a few times brighter than when I manually move the slider all the way to the left. Also, after using a widget to toggle to 0 and I check in the display settings, the slider isn't all the way to the left.
So I'm wondering what is true 0? What the widgets set it to or with the slider all the way to the left? Could the slider being all the way to the left actually be hurting my battery life?
No zero on the slider is technically not zero. You can confirm this checking your brightness sysfs file. You have to decompile framework and adjust some numbers. We can take it down to true zero or slightly above which would be much dimmer.
I did this for the atrix. Im surprised it hasnt been done yet for the nexus.
I know it is not actually 0 because if it was I wouldn't be able to see anything on the screen.
Is there anyone that has insight on my questions though?
I dont understand your question. Zero is not true zero unless we mod the framework. So your backlight is not "off". I dont know why youre getting so much drain.
But we should mod this anyway. Use root explorer and go to sys/devices/omapdss/display0/a6e8aa0 and open the brightnesd file. Note that value with your slider at zero and you will see a reading of 30 (0-255). So we can lower that down to maybe 5-10 and zero on the slider will be much dimmer = battery saving.
I have a similar problem. The max brightness is piercing and the min brightness is just a tiny bit too dim.
I have tried used root explorer to change the maximum brightness from 255 to 100 hoping that the slider may be more granular after. For some reason however I cannot update the max brightness file. I have ensured that it is r/w mounted and tried changing the permissions too. It says that the changes have been made and the original backed up. When I reopen the file it hasn't changed.
BTW, my 'brightness' file is at 10 when placed at the minimum brightness.
Try the newest AOKP.
Brightness controls.
I actually have NEVER used auto brightness...even back in my OG days.
And my X days.
Even when custom auto-brightness options were around I ignored them.
I'd simply keep it at around %20 of the default lowest value.
BUT...this is slightly annoying when you step into the sun and can't see anything.
With the newest AOKP you can even set the amount of brightness changes.
I set up four values.
I've mine set up for a pitch black room to lowest.
Average room to my previous 20%ish.
Bright (sunny) to 100/255
SUPER sunny to 240/255.
I didn't notice any added drain today.
But this was my first test.
I think this feature was actually kanged from CM9, but I'm not certain.
So far I have resisted the temptation to get flash happy and I am on stock 4.0.2 but rooted. Do I have any options without changing ROM?

We cant change that brightness file with root explorer, even mounted, unless we mod the driver first. It will likely just revert right back to its previous value.
However it is possible i bet to edit the driver. Would be a cool project. You could also try to echo your desired value in terminal. ie echo 255 > brightness. But you prob will get the same result as using root explorer.
Maybe ill look at the driver with my limited skills heh. Or the alternative is to mod the framework which is def possible to fix this, and easier. We did exactly this on the atrix. And the sgs2 had it done too.
Edit: i think i found the code for your granular request. Check lines 30 or so.

Still would be easier to do in framework instead.
Folks,
As most of u might knows that the CM10 auto brightness values are very low indoors, but its fine outdoors, any way to manually customize the minimum brightness value?
Settings > display > automatic backlight
Search the Play Store for autobrightness and you will get loads of apps that do it(i use "lux autobrightness")
Take care because some of these apps prevent you from installing .apk files of the market(you have to uninstall them, the filter they draw on the screen causes this)
Hi,
I always dim my screen 15-20% lower then the automatic mode do. Can i set it permanently lower between the lux-variables which are linked to 0-80% screen brightness?
Is this understandable?
For example: 20% screen brightness is set to 140lux
50% to 250lux.
I want to increase the lux or reduce the %.
It was so simple on my old Nexus 5 with Cyanogenmod ;D
Is there a xposed module or a app to edit the settings?
I dont want a app-icon in statusbar or a widget.
Thanks

Lux Auto Brightness app can do that but it's paid (not necessarily)
But with Lux i always have a ugly symbol in statusbar and it doesnt work like i want it to work.
What settings i should make in Lux?
GravityBox Xposed Module
Hi I find auto brightness too bright. Like every step could be darker / dimmer. Isn't there app or setting (for root ) that can set values ?
I have Franco kernel .
Hi all!
Is there any way for setting the minimum brightness to a specific value?
When in low light conditions, the brightness is set to extremely low using automatic brightness. I don't want to change it manually every time but it can be solved setting a specific value.
I don't see any adjust in developer settings.
It happens in both, stock and paranoid android.
Thanks in advance.
