Dark Background/Battery Life Correlation? - Nexus 7 Q&A, Help & Troubleshooting

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.

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.

Screen Burn-in

The burn-in is more noticeable in white/gray backgrounds...

Mother of GOD ! there are other icon imprints as well if I look closely !!
Hope it doesn't get darker than this ...
You won't find away around it unfortunately.
These screens are both fantastic and both sh*t at the same time. It's good technology but it isn't perfected. My original SGS went terrible. After nearly 2 years on it I could see perfectly the alarm icon and almost every icon I had on my home screen on light and dark backgrounds - It's a nice screen but it will only get worse within time.
As others have said only real solution is to keep altering your backgrounds and home screens but tbh I wouldn't bother, you'll still get burn from the time and other icons in the status bar.
Until Samsung sort them out and improve how they work it's just the way it's going to be
Whoa!! That is scary!
I have heard that there is no solution for a burn-in..? Thanks for the advice though. I'll keep changing the layout constantly.

[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.

Question on display, please

Sorry, on a black background you can see the glow of the light bulb as to form a stain?
I would not be just my problemi

It looks the same as every IPS monitor ever.
Great color, great brightness, but mediocre blacks when viewed from the side
If you mean light bleeding or bad panel uniformity, yes most (if not all) have that.
R: Question on display, please
And so the infiltration of light from the top of display is normal?

Yes it's normal on IPS screens. The degree that it "infiltrates" varies between devices. my First Nexus 4 had backlight bleeding that was more obvious then the replacement device I have now. The replacement's back light bleeding is barely noticeable.
I've owned various devices with IPS screens
Asus Transformer TF101 (I've handled about 5 different devices)
Asus Transformer Prime (handled about 3 devices)
Asus Transformer Infinity(handled just the one I owned)
LG G2X (Had multiple replacments)
Nexus 4
Nexus 7(handled 3: 2 32gb HSPA+ and 1 16gb Wifi)
All had some light bleeding to a certain extent or another. Some being much worse than others.
I have a RMA for a 3rd Nexus 4 (The one I have now I love, hardly any backlight bleeding and everything is great except there is this one dark vertical line from top to bottom of the screen that you can see on white/gray backgrounds. My original Nexus 4 didn't have any of that)
If my 3rd has worse backlight bleeding than the one I currently have I might just deal with the dark line on the screen on white/gray backgrounds on my current device as that's the ONLY thing that bugs me about it.

[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

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.
