How to make screen dimmer - Galaxy S I9000 General

I often use the phone to read in bed with the lights off. The screen is still way to bright even set to 0%. Anyone know how to dim it further?

If you're using the Aldiko ebook reader, just set the background color to black and set the text color to grey or some other dull color.

on 1% mine is very dim even in pitch black darkness, you must have sensitive eyes

I wonder if mine is behaving normally. I have set it to Auto adjust off, and slider to 0%, and it is still readable in bright light (probably daylight).

Maybe you have the same problem described here?

Get the Dimmer app from the market, it drops the screen "0%" brightness from 18% default to 10% and I find it perfect.

I just tested 3 apps on the market. Dimmer is good, but quite simplistic. Varies the brightness between "10" and whatever you have it set at. Apparently Android's idea of 0% is "18".
I also tried "Brightness Level" which gives a bit more control and allows you to set 0%, 25%, 75%, 100% and Auto. 0% setting in Brightness Level appears to be the same as the level of "10" that Dimmer allows. The program gives a percentage indicator of brightness.
Brighterrific may be very marginally 'better' at dimming the screen. It allows you to set a minimum and maximum brightness. If I set it to 0% in the program and then compare, it says the brightness has been set to -3% (according to the brightness percentage indicator in "Brightness Level"). The difference between 0 and -3 isn't very visible to me, but maybe it'll save slightly more battery life. I also noticed that clicking on Dimmer won't work after setting it to a level of -3%; maybe because the program doesn't recognise a level lower than it's default lowest level of "10"?
Obviously lower levels must be possible if Dimmer indicates that it's lowest level has a value of 10; it must be possible to set it to 0 or 1 somehow. Needless to say, if anyone finds a program which can set -30% let me know

Thanks folks. I have installed Dimmer and I am happy with the screen brightness.

Automatic brightness vs manual

Hi guys
Which preference do you use? Is automatic brightness option best for battery saving?
i remember it was an official battery saving tip for iPhone and wondered if it's the case for N1.
eh, just keep it on the lowest brightness... thats the best bet
the problem with auto-brightness is that it fluctuates a bit too much if you're in a room with localised lights and shadows... even in a seemingly bright area to your eyes, the display will go to lowest brightness... i just found it personally annoying, as it would usually fluctuate when i wasn't expecting, and to a lower brightness than i could stand... i've since stopped using it... i set my brightness manually to about 25%... for me that's a good balance between a usuable brightness for all conditions, while still giving good battery life...
I use auto brightness with locale which toggles it on and off based on my location. But even before I did that I really didn't notice to much of a difference in battery levels at the end of the day.
I just wish there were min and max settings for auto brightness. Cause I am pretty sure I have never needed the brightness turned all the way up.
i prefer auto brightness if it works. my 1st N1 had a glitch where the screen brightness used to flicker. on my 2nd N1 the auto brightness does not adjust on full scale........(if you go into 100% dark room, the brightness setting must automatically drop to 0)
I too found that the auto-brightness flickered too much. I downloaded Brightness Level off the marketplace and never looked back...
Auto-brightness fluctuates too much for my liking. So, I just keep it set to middle brightness.
the light sensor is unstable, so manually 25% all the time..
Auto brightness too dark
In my Nexus autobrightness works ok outdoors, but indoors it sets the light too dark. I wish it`d work fine because it's a waste of time adjusting it manually every time you move into different light conditions.
I've read Nexus users report different behaviours of their light sensors, maybe it is a bad quality component of the phone. Is there an app which can modify the sensibility of the light sensor? Would be great to adjust this sensibility and set brightness always to auto with a little more brightness indoors in my case.
manual, 25% - the best balance of battery and light for me.
i use about 60%. I hated the automatic brightness because it was darker than I would like most of the time.
My position is, I bought a phone that has a high resolution, so why not give it the brightness to make the color "pop" like they should.

Auto or manual brightness..that is the question

I have been experimenting with brightness on my sgs and how it relates to battery life. So should I keep the brightness on auto or the lowest?
I have noticed that when my brightness is set on lowest, the phone will sometime turn the brightness up a lot for no reason. I think it should be on auto brightness.
Ideas?
on the notification bar up there if you sweep it left our right it'll adjust the brightness too, just found that or. pretty damned annoying.
my brightness is on it's lowest always, unless I need to see in the sun.

Yeah.. In Froyo they don't have that "feature" (hopefully they don't enable it either).
I keep my light down to minimum too. I've had no probs looking at the screen here, but then again, it is winter and I am an evening person..
I'd say lowest setting is the best, the screen isn't difficult to see even at it's lowest. brightest just makes everything look more vibrant and awesome. you can have a separate brightness setting for the browser too.
i set mine to manual
the auto doesn't work well, i like it bright, and in auto mode, it is not bright enough for me

You are right. If you have your brightness set to Manual, you can adjust brightness by sliding left or right on the notification bar at the top.
It's a problem because you can by accident set it to high and therefore drain your battery fast.
I have setup Tasker to set brightness to 40 once every hour. 40 is about 16% of full brightness.

Automatic Brightness

Here's my dilemma... I like saving battery by setting my brightness level lower than the automatic setting (since the screen still looks great anyway), but I would like it if I didn't have to go into my settings manually to change the brightness level so that I can see the screen when in direct sunlight. Is there any way someone could develop a mod to have the automatic brightness, but about 20% dimmer? I don't know if it's possible, but it would be pretty awesome.

I have my screen set pretty dim, and use the Power widget to crank up the brightness if I go outside.
You can also you the "Screen Filter' app to make the screen x% darker than the current setting. (which even allows you to make it darker than the dimmest brightness settting, which is really nice on the batteries.)

I am current searching for the same thing.
temp solution is to Market > Dimmer (night mode) by geekyouup
It toggles auto brightness and sets back light to min. when on. click once, screen goes super dark, click it again, auto brightness take over. handy. (put it up to status bar w/ bar control and you can get to it when ever)
Problem with auto brightness right now is at it's lowest setting, the back light is still at about 25%. there is gotta be a way to change that in the settings.apk
or better yet, have an option to set your own ambient light to lcd brightness ratio for the auto brightness
option to set own ambient light ratio?

I'm search for this also. I believe you can adjust this in CM7 but is there is a way to do this that is not ROM specific? I'm currently using RoyalGlacier with Faux123 kernel and I find the auto brightness setting for dim ambient to be too bright and the bright ambient to be not bright enough.

Screen too bright, fix + save battery

Evo screen is brighter than most phones with AUTO light sensor on = more battery drain.
Just found app "screen adjuster". It works along with LIGHT SENSOR. I'm setting it to 50%. So it's half the brightness and you keep the auto sensor on.
https://market.android.com/details?...t=W251bGwsMSwxLDEsImNvbS5uZXRtYW5zbGFiLnNhIl0.
Going to try it out. I've thought the same thing for a long time. Thanks for the suggestion!
Tried this app out not sure how much battery it would save replacing the brightness with an app constantly running in the background considering it has to run 24/7 to maintain the brightness level I doubt it would save any battery if not kill it faster than the brightness level since 1. Brightness is off when screen is off but this is still running while screen is off and 2. The brightness only goes all the way up when you are in bright light so you can see the screen setting the app at 50% is really pointless since on auto the screen is at 50 - 70% when you are indoors

@Evil
I think your points are valid, but just wanna throw out that I think the OP is saying the baseline screen brightness is too high. At all levels.

It only sets Max at whatever level u set it to then autos from there, and it runs ~5mb ram constantly so it really doesn't do a whole lot it just sets, as an example, u set it to 80% with the app then on auto ur brightness goes from min to 80% and back to min or in between the two it doesn't dim all levels, and runs constantly so I would say its more trouble than its worth it would be nice if u could just set a lower Max and not need the app running 24/7

There MANY processes constantly running in the background, the OS is smart enough to pause most of these processes when in sleep mode (display off). For example, if you use the light sensor and your phone is off the sensor is not being polled anymore.
Setting 50% means if the brightness is normally at 100 it would be 50, if it was normally 50-70 indoors it would be really be 25-35 with the app.
Or a lower baseline, which I believe is the OPs point. But yes, running an extra ap is an inefficient way to do that.

The app doesn't pause it runs as a notification task killers don't touch it, and it doesn't work the way u think in lower light it will stay at 50% it just prevents the screen from going past where u set it it doesn't change the values of anything in the sensor just stops the screen from going above x% so if ur in a bright room where ur screen would be at 50% and u have it set to 50% it would still be at 50% not 25%, what I'm trying to say is the app doesn't work the way its advertised

This was on my list of things to be fixed nearly from the start but nobody, especially devs, seemed to care.

Display brightness
Based on experience what are the optimal display settings for the best battery life?
lol 0% is the optimum setting. really, the more its off, the more you save. the less its off, the more you save. its really up to your eyes and what you can tolerate. i just have a widget, at night i flip it to 0, and during the day if i'm out doors and in doors i leave it on auto, and if i'm indoors like at work, i leave it at 25%. what sucks is i don't smoke in my apt, so when i wake up i go outside for a cig and my screen's at 0, and i'm trying to read it in the sunlight to turn it back on lol... buuuuuut, i'm sure my way saves more battery than using an app that is constantly running

Auto-brightness still too low on 4.5.11

Hello guys, I installed 4.5.11, but auto-brightness is very agressive, many times i find it on the lowest setting. Any way to fix this? I just want it a bit higher.
Seems like Oneplus is having everything that saves battery on, from brightness to Doze. As some notifications didn't show untill i opened the app. Usually whatsapp. Personally, instead of 7h of screen on time, i prefer having "just" 6 and everything working good. Just got this phone, 6-7 hours of SOT on a 3300mah battery is insane!
This is very stupid. I have the same problem. I dont know why OnePlus don't make AutoBrightness ajustable like Samsung in Touchwiz for ex...
same with me, when autobrightness in darker room, display is always set to lowest brightness ever. really annoying.
On my side, I really love the way auto brightness behave on my OP5. Too much light is not good for the eyes.
Exactly, the user should be able to set a default level, then auto brightness goes from there.
For those who have sensitive eyes, you can always use night mode. It just block the blue light that is mostly responsible to keep is awake.
When the auto brightness is too low did you go into Settings / Display and move the Adaptive Brightness slider to your desired brightness? I am now in a very dark room and the slider isn't all the way down to the minimum. I can see my screen fine.

Yeah or i do it from the status bar. Still after a while it returns to a lower level. While i already want it on a low level, it's too agressive. I whish i could raise it by 10-20%.
Yeah, that slider doesn't adjust the adaptive brightness level like it would on a Nexus or Pixel device. It remains as a standard brightness level instead

Well, we could install xposed to fix the brightness. But then i don't know i want to install all of that just for brightness.
