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.
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.
Hi all,
On a number of occasions, I've used Market apps to control the screen brightness, either manually (like a brightness widget) or scheduled (using Timeriffic - a great tool for automatic profile changes throughout the day).
Apparently, these apps are not aware of the correct minimum brightness supported by the Leo, making it too easy to go too low, which essentially disables the display completely.
Touch still works, so if I'm lucky enough to remember the location of the widget/slider/controls, I may be able to turn brightness back up to a "sane" level.
For example, Timeriffic turns the screen off with a brightness level of 10% - 15% is the lowest working setting.
If I'm unable to fix it this way, I'm basically forced to reset. The problem is that Android *remembers* this setting after a reboot, and reapplies it just when the device is vibrated slightly at the "Android" logo animation. Thus, with a black screen, it is impossible for me to unlock the SIM, hard to unlock the screen lock, and virtually impossible to correct the brightness setting. I need to remove my data.img ("hard resetting" Android) and restore what I can from backups.
The problem also seems to occur with the standard screen dimming which occurs at about half time before the "screen off" setting. I can see the display start to dim, then it suddeny turns off. In this case, however, Android of course reverts to normal brightness at the touch of the screen or press of a button.
On a related note, I have experienced (like right now) that brightness range used by Android is much dimmer then normal. That is, using the regular brightness slider in Settings, I can only vary between almost invisible (min) and quite dim (max). Curiously, in this situation, the display can get *much* dimmer than normal, without becoming disabled.
Any ideas on these issues would be most welcome!
Workarounds found later in this thread:
- Shine a bright light on the screen - the graphics are still there if you look really hard. It's not a joke!
- Use Screencast in Droid Explorer to "remote control" your Android
- adb shell "echo 255 >/sys/class/leds/lcd-backlight/brightness"

I don't know these app(s) but if they are writing their settings and configured values into a ini or settings file, than you might be able to connect via adb and change the setting by this way.
With tools like Droidexplorer or ADB magic, browsing through the files should be very comfortable and you might find the correct file.
this happens on regular android devices ...i have a couple of them

What happens? That brightness is set too low, essentially disabling the screen, so you're forced to hard reset or perform some root magic? How do you cope with it? Or does it happen that the permitted brightness range is just dimmer than usual?
Btw, until there is no light-sensor support in kernel, you can't use such apps for the brightness
Stills a good advice
I have had the same issue with the brightness range being too low. The max brightness is really dim and the colors don't seem right. That may just be the dimming effect though. If I restart the phone it seems to take care of this. I have not had the screen go below the minimum level and turn off though.
is there a fix for this. i just experienced this problem
I experienced the same with Multicon widgets.. had to delete Android and start over

so that means if i do that i'll lose everything huh?
Theres no way to restore the factory brightness or factory settings for the android?

As long as you have a working WinMo it should be possible to edit the values of brightness, but I have no idea where this information is stored.
Deleting Android folder and unzipping again is esentially restoring to factory settings.
yea this happens to me all the time, its a *****. it cuts off at exactly 12% for me. what i do is have aldiko(a book reader) on the home screen. if i click on it and open a book i can just swipe on the left side of the screen to adjust brightness. since i know that its on the home screeen on the right side middle, i can usually find my way back to it.

any thing on this... isnt their a file in the android folder that i could maybe replace to restore to factory settings.
and could someone post a screen shot of their phone so i know where the numbers for the pin code lockscreen. tryin to get past that, then i can adjust my brightness
LOL I experienced it one time. And I must delete data.img to restore the phone. After this, I don't use any brightness tools (except ones already in the Android build).
If anyone have solution, please point us
Well i was able to get my screen back to normal. lol.
I didnt delete the data.img, i simply copied it and then removed it, started a fresh install, and then just marked on my screen where the numbers were, turned it off, put the old data.img back. Followed my marks, and was able to unlock it and then found the power control widget. And bam! screen back to bright...
This might work for you!
Erm... In similar circumstances I found this worked...
I was trying out different Android builds and I found a screen brightness widget. It had various available levels of brightness, one being 0%. As soon as I selected it I felt pretty stupid as true to it's word it gave me 0% brightness placing me in a similar position to the OP.
My Solution. I used my (very bright) led torch to light the screen. By playing around with the angle and beam width I found I could just make out the on screen graphics enough to re-adjust the brightness level.
Simples!
Just as " Justblair " said .. you can place your device under a very bright light thus you'll be able to see the screen and what it's showing .. idk what build you guys are using but in cyanogen you can adjust the lowest dim level so that any app or widget tries to set the brightness to 0% it's automatically set to your preset, 15% for instance.
I've only faced this problem once
Is it absolutely necessary to flood the main thread with all these useless noob posts?
It really has nothing to do with Android development on HD2 and should be posted in the General section IMO.

Cyanogen allows you a max dim level of 26 - which is too little on the HD2.
In Tasker, 30 is the lowest setting that still provides light. Maybe Cyanogen can be patched for the HD2 in coming builds?
Thanks for the tip on shining a bright light on the screen.
Another tip is to use Droid Explorer's "Screencast" feature, to view and control your Android's screen on your PC desktop. Of course, the brightness setting has no effect here.
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
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.
