For people that want to save some battery juice and think that the autobrighntess values are too high...I got the right mod for you.

I lowered the autobrighntess values in framework-res:

old:
Code:
    <integer-array name="config_autoBrightnessLcdBacklightValues">
        <item>63</item>
        <item>63</item>
        <item>63</item>
        <item>96</item>
        <item>130</item>
        <item>143</item>
        <item>171</item>
        <item>199</item>
        <item>227</item>
        <item>255</item>
    </integer-array>
new:

Code:
  <integer-array name="config_autoBrightnessLcdBacklightValues">
        <item>1</item>
        <item>11</item>
        <item>23</item>
        <item>35</item>
        <item>48</item>
        <item>55</item>
        <item>80</item>
        <item>150</item>
        <item>200</item>
        <item>255</item>
    </integer-array>

People who dont know what this mod is doing, a small explanation.

When you got your brighntess on "automatic" your screen brighntess will be set regarding the value of you brighntess sensor.

So if its dark outside = low screen brighntess,
if its bright outside = high screen brighntess.

But in my opinion the brighntess states of the automatic screen brighntess are far too high and wastes battery.

When you also compare both first values in the two arrays you see that the minimum autobrighntess value was at 63 as default.
So when its completly dark in your room/outside your screen brighntness is brighter then it has to be.
...so you have maybe already noticed that the manual brighntess you can yet is far lower then the minimum autobrighntess value.


Its a flashable zip and compatible with Leedroid Tweaks.
In the next version of Leedroid Tweaks there will be a toggle to choose different autobrighntess arrays:

normal, low, lowest.

But for now you can use this zip with my prefered values.

hf:

Pls make a backup, before flashing this zip.

Works great. It's not as over powering with the brightness now.

Yeah, but still need to test if that values are okay for daily use.
Could be that a few steps are too low, so wou wouldlnt see the screen as good when its bright outside.
Just tested it my office..will seeover teh next two days if that values are okay (-:

This mod seems a good idea.

Have only been using my phone for a day or so, but the screen does seems to drain the battery somewhat. Am hopeful that your mod will help.

It's a good idea to have different profile with LeeDroid tweaks.
