How to decrease backlight while keeping auto adjust?

Hi!
I wonder if there is a way to lower the backlight levels on auto adjust (or increase for those who think its still not bright enough). Point is I think having the backlight on generally lower levels will naturally increase battery life. I know I can change the the brightness to a fixed level that suits me - but that would just be right for the current situation. I still want it to adjust to different lighting situations. Ideas?

It would be nice if it was possible to change how dim the backlight gets on total darkness and how bright it gets on your average sunny day.
I've been messing around with the reg to see if I could find max and min values but I can only change manual settings, not auto mode using the light sensor.
One note though: The sensor itself uses battery to measure ambient light. That being said, if you spend most of the day under a constant light source (say an office) manually dimming the device should consume less energy since the sensor is not doing much good for you anyway.
I guess it's not your case. I had this app on my Cruise to change backlight intensity. never used until now. it works on leo (running 1.48 but that should not matter) and changes backlight in 25% increments. You can copy a shortcut to the startmenu and add a quick link to your home tab or map it to a hard or soft button somehow.
I wold really like to know how to change max and min levels on auto backlight.

Try Lumos - it's a backlight replacement that allows you to customise how you want your auto backlight to work, ie. what the minimum/maximum brightness is, how fast the backlight changes, etc.

Seems to work fine. Still some tunning to do. Thanks!

I'm using Lumos now and it works great! Simple to set up and easy to customize. Thanks for the hint!

lumos is great but I found it was draining the battery quite fast on the leo.
Admittedly I was using it with the wm6.5 Check for active programme only setting. I never tested it to see if it worked without checking that box.

As far as I can tell by now the batterylife appears to be rather better than before. I haven't put in any application exceptions and didn't check the one checkbox in the settings tab. I also use a custom curve where the backlight stays at 30% until the sensor hits about 400 (30% is plenty in my opinion and still brighter than my friend's iphone in normal light condition inside).

you should try AutoLight http://forum.xda-developers.com/showthread.php?t=548402
it works fine on Leo

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.

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.

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

Screen brightness settings?

I came from a Nexus 5 and had to always leave my screen brightness on about 1/3 in order to preserve battery. After playing with my 6P for over a month, I feel like the battery can handle a brighter setting (with my usage). But, I have concerns about burn-in if I put the setting too high since this is an AMOLED panel.
What brightness settings are you using and have you had any issues with burn-in?

I will get this started. I first started by activating the Adaptive Brightness under the display settings.
It makes the screen dimmer - to my eyes even though it sets the overall brightness to exactly half way.
I thought my whites looked somewhat grey at that setting so I turned it off and put my screen back down to 1/3 (LOL) and I am pleased with the results - especially at night as the whites look whiter.
anything past half at night burns in my retinas much less the screen.
I have not noticed any less Screen on time. I still get about 4.5 - 5 hours until it hits 15%. This is with location turned on and email push. I don't use twitter, facebook or any of those social apps the young people are using these days.

Is there an easy way to dim the screen to the point where you can't see the picture? I stream the phone in my car, which means it will get hot with charging, screen on, and high usage simultaneously. Since it is an AMOLED screen, it would not allow for screen off like other devices. Seems like without this, burn in would be a big problem for me.

I would think that you could just do the 2 finger swipe to bring it to the default menu. Then set the slider down as low as possible until you can barely see anything. I took a 5 hour drive today with my Nexus 6P with the girlfriend and had it plugged in for at least 2 hours at a time. My phone did not get really warm while either plugged or when running on battery.
Also I have enabled the System UI Tuner and now my phone screen only stays on when plugged into the power source if I select "stay on when plugged in"

No burn in issues? I would think there is a way to reduce brightness beyond stock but I don't know enough to do that at this point. Perhaps through Xposed it something.

I had a gnex that I kept on low brightness and refused to get another nexus until battery was straightened out. On my dmaxx, I kept the brightness high and no burn in on the amoled. The 6p isn't as good at battery, despite being huge, but it's good enough. I keep it on 60-100 brightness, using lux to adjust it as needed. No burn in so far

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.
