I was wondering if someone could create (or if there already is) an app that will dim the screen a lot more than just setting it to 0. I work late hours and come home, just wanting to unwind and play some solitaire. I'm blinded by the screen. I know that there are night/clock apps that can do this. Thanks!
I second this request. The screen is quite blinding in a dark room. A night mode would be nice too have.

I would pay for this app, blows my mind how they could make a phone that can't dim lower. Even when setting brightness to 10 with Dimmer it's a real pain using this phone in the dark.

I would also throw down some of my hard earned dollars for something like this, i want to preserve my battery and the dimmest setting isnt making me feel happy about things
Why not just slide your finger across the task bar from right to left and it would lower the brightness to the lowest setting. To brighten go the other way.
Way easier than another app.

Thanks, but not what I was talking about. I'm talking about lowering the brightness past that for nighttime usage. I know it's possible; I have a bedside app that lowers it way past the default.
BTW, that trick only works with Auto Brightness off.
yeah this would be nice. also, having those cool filters like on CM6 would be nice too. the red filter is great for checking your phone in a dark movie theater.
Does anyone know how to dim Down screen even more than it says on the settings? Like ex. If you use the stock browser it gives you the option to dimmer to (high power save) so it dims more than normal... Can I do that when out of browser?

I believe you have to use apps found on the Android market. That was also the problem I found with this phone. I'm used to Samsung phones allowing you to maker the screens dim extremely dark right out the box. The Note is my first Samsung phone, and it really doesn't have that many brightness settings. The lowest setting is still fairly bright. I downloaded an app called Lux from the market, and it's amazing. I can make my phones screen almost pitch black at the lowest setting.
Nice thanks I just got lux and it better than the screen filter

Be carefull i used one that dims it to 0
and i did that accidentally and it stays in the settings after a reboot , i had to blindly find the app on homescreen and luckily got the dimmer to 15% brought the daylight back

The app called Dimmer will take you from 10 to 0 (10 is as low as you can go with the stock brightness control). However, I later found an app called Screen Filter which works even better - you can make the screen even darker, I found 0 to still be very bright in a dark room.
Even better, you can set up Screen Filter so it dims the screen a small amount all the time to save some battery life.

I really didn't like screen filter as it ruins the clarity when you dim... I used it on my evo and it was good while it lasted, but as Dr. Evo directed me to lux, it's a great app as it actually dims the brightness, and doesn't distort the screen with a filter

Try this app called LUX. It allows you to customise brightness.
The paid version allows dim below "0%".
You can set it to something like -40% in a dark room, and normal brightness when you're outside. Basically, it's like auto brightness which you can customise. This is so you don't have to on/off a screen filter app.
And yes lower brightness saves battery.

i just tried this app and it killed my battery faster than using screen dim because this program is constantly running on the background. what settings are you using on it?
Sent from my A100 using xda premium
I'm an author of a program named Custom Auto Brightness, currently it's not under-dimming automatically but it'll be added soon.
Meanwhile, could I ask some of you to test it? I'll provide apk if anyone agrees. The problem seems that PoverVR GPUs seem to have problems with screen shading like in Screen Filter and the like, I'd like to check if I were able to circumvent the problem or not.

Having something run in the background doesn't mean it's using a significant amount of phone's battery. The amount of battery saved from low brightness is much much more than the battery used for Lux to compute brightness level. Of course I did not test it, but it is common sense: as the display uses most of the battery. You can check your battery use in settings.
Lower brightness, longer battery. Lux doesn't even appear in battery use. My screebl app, which constantly uses CPU to check for orientation uses only 3% in battery use.
Download ES task manager to see what's running on startup, and look at what you do not use, it'll probably shock you.
As for my settings in Lux, I set it to dynamic and so far my linked samples are:
Lux ----- Brightness
2 --------- -40%
25 -------- -25%
550 ------- 20%
20000 -----100%
Been using these settings for a couple of weeks, and no problems. I have also added picture viewers, camera apps, and video players to ignore/compatible list.
Another tip to save battery which most already know: use setcpu to underclock your phone when screen is off to 300max/300min, or 600max/300min if you use your phone for music. Needs root though.
well i noticed after i wake up in the morning the battery has gone down so much more after i started using lux. i disabled it and everything was better. it probably used about 10% more battery in 6 hours.

I can say the same about battery drain. Been off full charge now for an hour, already down @ 78%.

I use the brightness control from widgetsoid. I leave it set at 10% and my battery still hase 40% or more charge after all day and evening, even though I read on the train for about 1 1/2 hours and do moderate email ---huge difference from auto brightness setting. Tap the widget to go to auto brightness when outdoors (although, frankly, I go days without using it outdoors so this works great for me).
Hi guys!
I just bought LG L5 II. It's still UNrooted, so I need a brightness control that doesn't require ROOT privileges. The reason is quite simple - the minimum brightness is too bright, when you're NOT outdoors (if you're outdoors, you better set the brightness on 40-60%). I'm posting here because it doesn't matter If I have Motorola or LG - the principle is the same - display is too bright.
I've installed Screen Filter. In this topic some of you lot are chatting about Lux app - is it better than Screen Filter? What's your opinion? Obviously I want to save some battery and to use my display at night or indoors (without causing pain to my feelings and emotions ).
I will test Screen Filter for couple of days and see what's what. Hope some of you have tested it already and give me some tips. Cheers!
PS: Sorry for reviving this old thread mods, found it on Google, dunno if there is a newer one 'bout the same problem.
I think Lux and other screen brightness modification apps use a transparent layer over the main ui and we actually darken and brighten that layer running over the Ui instead of setting a further down limit to the screen LCD power value. This might be the reason that using Lux or any other screen dimmer app consumes more battery~ the screen LCD uses same power and in addition an extra app is running in the background continuously . It is only the transparent layer that darkens to save your eyes in dark atmospheres~ LCD power consumption remains the same.
^^ This right here is what I've been wondering for some time, because I suspect that at least some of those apps work that way, and is also likely imho what the OP was really asking. Yes, everyone knows the display is by far the largest drain on battery, and so lowering the brightness helps with that, so the question is does the app in question actually do that or does it simply provide a customizable overlay, as the poster above me speculates. Because if an app is doing the latter, not only will it not conserve battery it will actually drain it more, to a point, because the actual brightness is still the same (even if you don't "see" it) and the app itself is running all the time. Granted its consumption may be very low, but the point is that scenario certainly wouldn't SAVE any battery. And my guess is that within this group of apps that are the focus of this thread, some are simply overlays and some (the very technical ones) are the real deal, and it's a question of knowing which to pick. What I'd really love is for someone who is very technical in this area to see this thread and provide some definitive info.

This is partially right. If you have an LCD, you are just dimming your screen, not saving battery in the process. If you are using a LED screen, the app's will save battery since LED pixels can be individually lit. Using black or battery saving backgrounds will also help your battery life on LED screens. This is one of the reasons why LED screens are much more preferred than LCD.
I was messing around with the settings on my phone to try and eek out some more battery life. I noticed with the stock battery monitor that the screen was using the most battery (as is expected) so I turned the brightness setting all the way down using the slidebar in settings.
Then I went into the Sprint Zone app, clicked help, then my device, then power controls. There it shows what is turned on on the phone and a general breakdown of how much those things are drawing on the battery (kinda nifty). On the lowest possible brightness setting it says it's at 11% and that that's "medium" usage. Is there a way to get screen Brightness lower? I just find it odd that it still registers as medium usage on its lowest setting...
Also has anyone noticed that on the "Automatic" screen brightness setting that the screen doesn't go as dark as it could go when there is a low light condition? For example if I'm sitting in the dark with auto brightness on, I can turn it off then make the screen darker manually than it would go on auto.
Any thoughts? Or fixes?

Try rootdim. Also, the screen brightness is going to be mostly controlled by the kernel, so try using a different kernel or build one from source.

It's not in the kernel, it's in an xml or something. There are seven brightness levels (I think it's seven) based on lumens, and there's an associated screen brightness value assigned to each on a scale of 0 to 255. Stock auto brightness levels set the bottom three levels to the same brigness value. I think it's 63. Setting the brightness manually, you can go as low as single digits, maybe even zero.

That's cool you can edit the XML files, but how can screen luminosity or display not be part of the kernel or kernel modules? I have an HD2 with CM7 on it, and through installing different kernels and whatnot, I can get different features for display like render effect, auto brightness, and whatnot. Is this only just for sense ROMs then?

So maybe the stock rom doesn't let you zero it out? It's posting the lowest value as 11% as read by the Sprint Zone app. Maybe they do it as a safeguard against setting it too low and not being able to see the screen to turn it up when it gets in a brighter environment?
That's a funny thought, I could see me kicking myself over something like that. Would be nice if we could make that call on our own though, wonder how dim it is...and why not make the auto brightness go to the lowest setting (or perhaps even lower than the stock setting)? At least then it would ramp back up as needed.

Did you try rootdim? I'm pretty sure you can dim the screen lower than stock with it on this phone. I've only used it on my HD2, but it worked well with it and It's free.
Nm rootdim only allows the screen to go down to a value of 30. You can set lower values, but it doesn't change the brightness.

Correct - stock only lets the brightness go down to 11%. I'm not sure if auto brightness will ever set it that low though, doesn't seem like it does.

Yea that's what I'm saying it doesn't go to the minimum. I mean I'm sure the battery savings isn't much, but another usefulness of it going that dark is when you check your phone at night in the car you don't want the phone to be all lit up inviting attention.

I think 11% is probably dim enough for most cases. If you have a dark background that will help with the car situation. The only time I find it still too bright is when I'm laying in bed at night. I haven't rooted yet so I can't comment on the solutions others suggested but give that a try. You probably won't save that much battery though unless you're in the dark a lot.

if i'm correct, what screen filter does to make the screen looks dimmer is it "puts" a black image on top of the screen, so it always runs in the background to make the screen dimmer
on my tf300 i use rootdim, it actually lowers the brightness settings the way samsung/android/system does, the difference it lowers more than the system allows, even to completely black. so after you use it to lower the brightness, it doesn't have to always run like screen filter -> no (or at least less than screen filter) battery drain
I have had great success using RootDim on my Acer A500 (rooted, stock ROM). However, I could not get the brightness to go any lower than the system minimum when trying it on my Galaxy Player (5.0, rooted, stock ROM).
If you're on another ROM maybe you'll have better luck or there's always the Screen Filter method. Or if anyone else knows of a way to do this I'd be curious what worked for you.
yeah, your best bet is a third-party app that lets you specify the actual brightness level.
