Dark Background/Battery Life Correlation?

Hello all,
First time poster here with a pretty simple /silly question... If you use darker backgrounds, reading apps, themes, etc... (as opposed to bright /light ones) does it save battery life? I read somewhere that it doesn't matter and that the screen uses the same amount of power regardless. I also read though that some types of screens are able to turn the black pixels off saving battery life.
Thanks for any input.

For amoled screens a little bit but LCD I don't think so.

Excuse my ignorance but what type of screen does the N7 have?
Thanks for the help.

LCD.

Yep, with an amoled display you can save some percents(the exact value differs over the display/phone/app used) over a darker background due to the techique used. With a lcd display the only thing that influences the battery time is the screen on time and the brightness.(of course this two points also count for the amoled)

Thanks everyone!

Nexus 4 display and speaker

I usually keep my phones on full brightness. I'll deal with the battery draining because I love how it looks with full brightness. Has anyone noticed the display on the n4 kind of adjusting sometimes. I have noticed sometimes it changes to a little darker or a little brighter while using the phone.
I also noticed when I am talking on the phone with the speaker on sometimes it shuts when opening an application or sometimes even without opening an app and switches to regular ear piece. Sometimes it will stay on speaker but go lower.
Anyone having these issues? Its not a deal breaker or anything I still love it. I know phones will always have their issues, I've had ever nexus and the g1. I just want to know if other people are having this issue.

Its not auto brightness, my phone does the same thing. Its hardly noticeable but I find it strange too

My guess is glitch hardware. Lg is known for making inconsistent quality. Terrible QA. Just because its made in Korea doesn't means its better than in China.

I don't know how you can use this display on full brightness it's too damn bright! Strains my eyes. lol I tend to keep mine around the 25% mark

It's adaptive contrast, runs independent of your brightness settings and there's not an option to disable it. You probably notice it most when moving from a largely black screen to a white one.
I think I remember first hearing about it's use in a Galaxy S2 review, my TV does the same thing on its dynamic setting.

[Q] Nexus 4 weird display issue

I got my Nexus 4 yesterday, and just today I've noticed that when in dark screen (locked, or simply the settings page) and outside of the house I see kind of weird black lines on the whole display screen, going form top to bottom making some 3 small square shapes after the others all over the display, can be obviously seen when display facing bright sky outside in almost any angel, but in room light barely can see them with certain angels.
will make a photo of it asap.
p.s. I've never seen a notification light yet on the middle bottom of my device.
Anyone same "problem" with display?

Its the digitizer.

Could you link an example image from goolge or something to make sure it is what I mean? can't seem to find something alike..is this normal?

I can confirm that its the digitizer I too have found that with this phone it is very easy to see even with weak light I see it when I get the right angle. It looks like you described but the vertical lines look more like dots arranged neatly than lines on mine.

Just noticed the same thing on my device. Thought I was tripping out maaaaaaan
Sent from my Nexus 4 using xda app-developers app

Its the digitizer, its normal. I think its because of the "zero gap" technology thing ; the display and the digitizer are right below the glass.
As for the notification light, download Lightflow from the Play Store. Works great.
Sent from my Nexus 4 using xda app-developers app

For the notification LED, make sure you enable the " Pulse notification light" option in Settings->Display. Using Lightflow on top will give you lots of customisation options though.

I am now noticing the same issue in my nexus 4. If it is because of zero gap technology then why it is not there in iPhone 5 and other phones which use this technology?
I also notice that my brother who got the phone some time in November 2012 is not having this issue. I got the phone in Jan 2013...is it issue with only the new lots?
What google and LG are doing to address this issue?

Its the digitizer. I mean seriously why are y'all complaining about that, its normal.

[Q] Any Nexus 4's Without Backlight Bleed?

I've already tried out 3 brand new Nexus 4's, and they all exhibit light bleed around the top right corner.
I know, I know; I'm being obsessive or nit-picky. But, just humor me for a second, and chime in on the topic....
Anybody got a Nexus 4 without any lightbleed whatsoever? You should be comfortable around 30-50% brightness and have no uneven backlighting around the top border....
Does a perfect Nexus 4 even exist?
Thanks fellas

No bleeding here

No bleeding here mines the first batch HW Revision 10 :good:

I swear my Nexus 4 is the best phone I've had! Better than the SG3 and the One X I've owned! BTW no light bleed on mine.
Sent from my Nexus 4 using xda app-developers app

Minor light bleed at the top & bottom.. although it is very minor. I really have to try to see it. I would say for a normal person, they would think it has "no light bleed". But to us perfectionists yes it's there.

I know this is asking a lot, but would someone with a perfect device mind posting a pic with your brightness turned up with your notifications dropped down?

No bleeding here either and I'm on Rev 11

Lots of light bleed here in the top right corner. Nov 2012 version, rev10
Don't really care though.

No bleed and I bought mine at an insanely bright tmobile at sunset.
Sent from my Nexus 4 using xda premium

Maybe for some of the people who say they have a perfect device, just dont notice it or their brightness is too low..
someone, please, put my OCD worries to rest and snap a shot of your phone with no lightbleed with the notification dropped down with at least 50% brightness.
I will be in your debt.

Is this what your looking for? Sorry I'm half ass sleeping right now.

Nexus 7 2nd generation FHD display

I got mine today from Amazon uk and I must say that I am a bit disappointed from the screen. I watched many reviews and all of them were talking for one of the best displays out there. Well they probably haven't seen Samsung galaxy tab 7.7 super amoled + magic. I will post a video later on with both devices playing a trailer from imdb.
Don't get wrong here. I love it but it just can't display black. Period.

I compared the display on mine with my wife's iPad4 with the retina display and I think its just as good if not better than that. Plus at this price point you cant go wrong.

I couldn't agree with you more. The Galaxy tab was retailing at 700 us while the nexus a fraction of that. However the amoled display on my "old" Sammy tab 7.7 is out of this world. The black and the color reproduction are just stunning. I was used to that display and the gnex looks to me a bit washed out. Other than that is is really great.
Sent from my GT-I9505G using Tapatalk 2

I suppose he is talking about the colours?
They are a little bit washed out and the white is a bit yellow when compared to my nexus 4 that has francos gamma settings applied.
However, when gamma controls are ported to the Nexus 7 the screen will look great with some tweaking. :thumbup:

Guys you do realise this screen is one of the few ones actually calibrated in the factory at two different stages and that the colours are accurate. What you see in the unfortunate Samsung models etc is a screen just with ridiculously saturated unrealistic colours. You guys need to train your eyes to see real quality...

400% saturation doesn't make a good screen
