Hi! My question is: Is there a BIG difference between leaving lowest brightness setting and auto-brightness? If so, how much? (Hours, battery usage, etc)
Thanks! I hope this thread will be informative for everyone..
Auto-brightness consumes more battery because it is constantly changing brightness, if you want the best battery power just use the lowest brightness
as aaitken said auto brightness consumes more battery . its better to use low brightness and use a brightness control widget from market and change the brightness manually when required

If you have a stock firmware, or a stock based ROM, you can adjust brightness anywhere you can access the notification bar. This is built into TouchWiz. Just hold your finger on the notification bar until you see the pull-down shade, and slide your finger left or right to adjust brightness.
I leave my brightness on lowest and adjust as necessary with this, i.e. when I'm in a bright setting, and need to turn my brightness up.
Also there is brightness options in AOKP with the toggles and in CM9 (and most other AOSP roms) as a power save widget bala_gamer's option's also a good way
Thank you very much for your helpful answers..

I figured this would come along by now but for some reason it hasn't. On my iPhone I could set my brightness that the auto brightness would adjust accordingly. Because the auto brightness is generally too bright or too dark. Also maybe adding some timing controls for how long before the auto brightness adjusts. The displays in these devices suck down the battery like crazy this would help significantly.

I too thought we might have seen this by now. I know there have been some tweaks in ROMs, but a slider that sets the sensitivity or the upper/lower limits would be excellent.
u talking about this? http://forum.xda-developers.com/showthread.php?t=708660
extended controls has a auto brightness controller sort of if thats what your looking for

Extended controls has an Auto Brightness setting, same as Froyo Power Control widget.
What OP wants is auto setting where you can control sensitivity of light sensor.
Ok I'll try explaining again. Communication isn't my strong suite. Basically, on an iPhone you can set auto brightness, then under auto brightness checkbox you have a slider that calibrates the brightness throughout the range of the ambient light sensor. So it's still a brightness control it just works in conjunction with the auto brightness setting. Being able to fine tune the brightness throughout the range of the ambient light sensor would be a bonus because with the current auto brightness I can barely see the screen in daylight but it's not maxed out because I can still adjust it all the way up with the power control widget and the opposite is true at night, i could go dimmer at night and still see the screen clearly. Strictly copying the functionality of the iPhone wouldn't fully address this. An app would be ok I suppose but I'd much rather see a system mod. I really hate apps like Trackball alert, nothing against the author I just don't like running an additional app to address the lack of a feature in the OS itself.
Good thought
I agree completely. I'm a recovering iPhone user and the adjustable auto-brightness is a feature that I desperately miss. One of my top complaints about android.
This idea is fantastic. It's something I've been thinking about too (never knew iPhone has it though)
When indoors I sometimes find auto brightness too bright. When outdoors and its sunny sometimes its upper limit is not bright enough. In both situations I have to turn off auto.
Actually last night I noticed that auto brightness was dimmer than the lowest brightness setting. I reckon that a lower/dimmer threshold should be available too on the manual brightness settings.
I just installed Android 2.1 and rooted it. In the brightness setting there is no longer a selection to choose the Auto-brightness setting, just a slider for low and high brightness.
Also I noticed the Power Widget that has the brightness control switch lets you switch between low, auto, and high, but while in Auto (the dimmer setting while the button is ON), the sensitivity is very poor and will only brighten the display by about 10% while moving from a very dark environment to a very bright environment.
Yup, i agree. This sucks. Although i had forgoten how nice everything looks with the brightness turned up. All the same id like to have it back.

cant expect everything in 2.1 to be perfect. Yes it has taken them a while but i wouldnt expect it to be without any flaws!
At least we got it finally. WOOOOOOOOOOOOOOOT

I thought this today too but the Auto Brighten IS there and still working, just a bit differently.
Initially you choose the 3 levels of brightness on the quick select from the 5 widget icons. This is the brightest it will go, but if you go from a dark or light room it DOES indeed still adjust.
I noticed this after a bit today just standing in the kitchen watching the movers do their thing at my old place. The sun was ducking in and out of the clouds and the auto function was working fine. I tried it in all 3 modes, the only one it doesn't do anything in is the least bright mode...the one I noticed it most is the middle bright mode.
So YES, it is indeed working, just differently.
The auto Brightness sucked in 1.6 anyway. It was never that good for me. I use a brightness widget to adjust it.
I much prefer the way it works now. Seems to be a lot more user friendly tbh
have you tried the setting in spare parts (from the market)?
I've not tried it myself, but I know the auto setting is there.
Auto birghtness
Hmm. I have the 2.1 update and I have set the brightness to the low setting in the power widget. The brightness still adjusts automatically, and I don't want it to. I want it to stay at a low level all the time to save my battery. How?!
I found the autobright option (middle setting on the widget) doesn't brighten the screen as much as in version 1.6. Is there a setting that can be modified to increase this threshold?
When i set it to full bright (last setting on the widget), although very bright and crisp, I find it kills my battery life.
The only settings I've found about brightness are the ones of the widget and the ones in the setup menu, under the voice "display settings", I didn't found anything you need but if I'll found I'll let you know, specially if you can tell me how to disable the autobright option at all, leaving the brightness at a value that I want, without any changes by the sensor. I hope this is possible, because my battery is really eaten by my display
I use the Brightness Profiles app. It seems to hold the settings after reboots.
Is it possible to tweak the auto brightness levels now that we have EC10 kernels (someone had told me that auto brightness levels were controlled by kernels)?
It seems like this would be an awesome opportunity for some battery life savings...
Why not just keep it on a low setting, then bump it up whenever you need to?
Just slide your finger along the notification bar or use a widget.
I know I know. I just thought itd be nice to get some use out of the ambient light sensor...
Is there a way to show the current display brightness set by Android's "auto" brightness?
I'd like to analyze sometimes in what level it's being set by the light sensor so I could consider controlling manually.
Sometimes it's just too high for the ambient, and could be using less battery.
I tried some apps on Google Play, like Brightness Motion, that show current screen brightness on widget or status bar but when in auto mode they'll only display "auto" instead of the percentage.

Have you tried this one? And here's another one.
Let us know if you find something that works.
