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.

My screen is too bright, what will make it dim below "10"?

Even on the dimmest settings, the Vibrant is too bright for me in bed, where the light disturbs my wife.
It seems that, with root, you can lower the brightness further - at least on other phones. Is there any way to do this with the Vibrant?
Thanks!

The "Dimmer" app will toggle it from your current brightness down to 10 but if you find something that will go lower let me know.

It has an automatic brightness control based on input from the sensor. You may need to disable this in the settings too, but I would think it would be automatically dimming itself already in a dark room.

Right, but that doesn't get dim enough in some situations and the minimum brightness you can select manually is 30. "Dimmer" will take it all the way to 10 but I would like to see something that would take it to 1 or 2.

I agree. It's too bright in low light situations.
If you find a solution please post it.

Try the Screen Filter App from the market. You can get UNBELIEVABLY low brightness. Which means much better battery.

+1 on screen filter. New version now dims taskbar too.

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.

Automatic Brightness too low

Automatic brightness enabled on my new OP6T. It constantly goes too dim, where I have to slide it up some to see the screen better.
Unlocking the phone an hour later, in same low light setting, the screen has auto dimmed itself too low again.
Anyone else feel it goes too dim on its own? Or have a solution for me?
A maximum dimness setting would be nice. Not sure if that exists though.

I'm with you 100% it keeps defaulting back to a brightness that's way to low for the environment have to constantly raise it manually. A minimum brightness setting between certain hours would be great.
I wonder if something like that can be done in tasker, keep automatic brightness on, but set the minimum to 25% or so during certain hours.

This exactly!

It's generally really low. The worst is in the dark, it's almost unseeable, unless you manually adjust it.

Phone has great battery life I just crank it 100% outdoors and 75% indoors.
I agree with what others have stated but that's why the battery life is good...I'll drain it to appease my eyeballs.

Does lux work?

hopefully can be fixed with an update...

My phone was like this for the first day or two. After that it's been just fine.
I don't know if it fixed itself, or I've just gotten used to it. I'm thinking the first because it was really dark.

I have observed this on different phones. So I suppose this is an android issue. The brightness goes too low than its supposed to or it will keep adjusting. I've tried lux auto brightness on other phones, it works perfectly. But due to lack of updates I've stopped using it lately. Custom ROMs seem to handles auto brightness very well. I've tried Cyanogen and Resurrection remix on moto x play and Honor 8 pro, auto brightness was never a bother on them. Which was not the case with the OS they came installed with.

I've compared this yo my pixel 3xl and in low light situations its noticeably darker. After a few days I'm already used to it.

The smart adaptive brightness adjusts to your usage over time, once you manually raise it afew times in various situations it will adapt to this. Mine was dim to begin with but after 2 days it's fine.

LUX works after enable it in usage access. Settings>apps&notification>special apps access>usage access.
