Will I get more battery life if I increase black colours? - Galaxy Note II Q&A, Help & Troubleshooting

I was wondering from my understanding the amoled turns off the leds that are within the black area of the screen display. So if I turn my wallpaper and most layouts into black colour will that help reduce the battery consumption through the screen or will it be almost insignificant?

I would say insignificant at the risk of not enjoying your phone. Does it really matter if you squeeze out an extra 30, maybe 60, minutes at the expense of not just using it and enjoying it?
Everyone spends too much time obsessing over cranking out every last little bit that they forget to stop and smell the roses.

According to the quoted site, a white pixel on a SAMOLED screen takes up nearly 6 times as much power as a black pixel, as all sub-pixels need to be lit fully. Being that the screen is by FAR the biggest consumer of battery on our devices, I'd suspect that turning down brightness and throwing on some black backgrounds will make a difference. The site also analyses average battery gain (on non-pure backgrounds):

This guy tested SGS3 and concluded 3 hours extra battery life, regardless of brightness: http://forum.xda-developers.com/showthread.php?t=1882467
If you're indifferent, then pick black. If you can't stand black, then pick white.

In my line of work, involving alot of field work where I do not have the luxury to charge my phone whenever I want, it matters. Besides I do smell the roses...even in black.

Incase youre wondering what this job might be that doesnt even have electric sockets in close proximity ..im trapped in a chamber for a month doing saturation dives where I only get to charge my phone once every 2 days.

Then I'd say get a second, even 3rd, battery and crank up the colors.
And, to be fair, your situation is obviously on the extreme compared to everyone else trying to max juice.

Black is beautiful on amoled. ..I use the dark background on tapatalk. ..I wish Google currents had a black background. ..hope they introduce it.

Yes, it will help a little bit.

[Q] These HD sAMOLED screens kinda suck

EDIT:
tldr: Too much Vertical lines on my GN. It's very visible and worse than the graininess.
I know others won't agree with me here but, this is a $650+tax phone.
A phone of this price deserves a perfect screen.
Look at iphone 4 / 4s. Sure the screens are small but there are NO ISSUES WHAT SO EVER. The IPS they use is basically perfect.
Ever since I got my Galaxy Nexus, I have had concerns regarding the screen:
1) It kills too much battery. Battery settings show it killing 50 - 70% of the battery WITH AUTO BRIGHTNESS ON.
2) There are LINES EVERYWHERE. The whole screen is very grainy unless the brightness is very high. But then it's too bright (especially for low light reading) and it will probably kill 80%+ of the battery....
3) Pentile matrix. Sorry to say but it's very noticeable. This is especially true for text that is white or red.
Download this app:
http://www.appbrain.com/app/dead-pixel-test/net.ujacha.deadpixel
Cycle through the colors and notice, Green is the only true 720p. The red/blue look terrible and you can see the sub pixels (because there are only half as many of each compared to green)
Overall, it's a great screen. I can live with the high battery drain (large screen). I can also live with the pentile (high resolution, excellent blacks).
However, the lines / grainy textures everywhere is just unacceptable. I could even live with the grainy texture but there are a few vertical lines that are VERY noticeable.
Should I get mine exchanged ?? I'm just afraid that the replacement may be worse....

The definition of 720p is based on pixel arrangement, NOT subpixel arrangement. it is a 1280x720 screen. By your definition, a 720p/1080p screen is only true if it is an RGB subpixel arrangement. So you would also say that the Sharp Aquos Quattron TVs that have a yellow subpixel are more than 1080p.
If you expected the equivalent of a current generation plasma screen shrunk down to a 4.65" screen in a phone, that's just unreasonable. Its the first iteration of this tech. Lines and grainy screens are AMOLED's version of lasting burn-in and high power consumption on plasma.
Also, everyone references the iPhone. Why? The colors are inaccurate and undersaturated, and the contrast is too high. It is NOT a calibrated IPS panel. Name-dropping IPS technology means nothing.

They are all like that.. it's a flaw of the pentile matrix that they used to build the screen.
auto-brightness makes it worse.
What's the point in setting up a scenario to expose the flaws that exist in every (gnex) screen?
Most people's use-cases won't involve that scenario and they'll be able to enjoy the screen without a problem except for battery life, but battery life is always going to be a problem for a display larger than 4".
In my day to day use of looking at things other than dark gray backgrounds and solid color fields, the screen looks fantastic and has one of the highest pixel densities of any phone display out there. (Nitro HD, Rezound, LG's 720p screen phone and iPhone 4/4S have slightly higher pixel densities.. but they're all a cut above most other phones available)
ok the wife and i upgraded at the same time...........i chose the GN she chose the iphone 4s.
and honestly i would be gutted if i had chosen the 4s !!! ive worked a lot with the sg2 and for me the screen is too 'in your face' colours are vivid...the GN screen has a great balance.........and well going from the from the GN to the 4s ..........jeez the 4s is tiny
That first point drives me crazy. It's a percentage of battery use, do you get that? It means that if the phone uses almost no power except a little when the screen is on, then the display will be using most of the battery.
What you WANT is that. The worst is when cell standby eats up all the battery. That means it's draining just sitting on the table.

OK fair enough.
People have been *****ing and complaining about this phone not coming out fast enough for months now. Now that it's out people are logging in here to ***** about it not being perfect.
All I can say is that some people are creating a lot of needless suffering for themselves. At least keep it to yourself if you are going to go through life with that kind of an attitude.
If 14 year old me could have seen this phone in 1991 his head would have exploded.
I'm not an expert, but I just sold my Bionic and got the G. Nexus. The pentile on the Bionic drove me NUTS, but I LOVE this screen. I don't see ANY screen door effect, and I have loaded a few HD Videos on it and watching them is GORGEOUS. The colors are amazing and blacks are better then my 55" Samsung LED with an 8 million:1 contrast ratio. My roommate has the iPhone 4, and his draw dropped at this screen, and we held it right next to the iPhone 4. Only complaint is video recording is shaky, glad they are adding video stabilization in 4.0.3. OH, and I looked at my battery usage and the display is 68%. I bought the 2100mAh battery (for 25 bux, and barely any size change why not) and am getting a good 8-9 hours with a lot of use out of it which is about what I got on my Bionic with the 2760mAh extended battery. So maybe the screen is just by far, the most power intensive component, hence the high percentage of battery use. Anyway, this phone, like all others, could use improvements in some areas, but I absolutely LOVE it. And am SO GLAD to be rid of my Bionic (GOOD RIDDANCE)

I never complained about it not being out lol. Hell I didn't even line up, just pre-ordered online and waited patiently....
It's just that: THE VERTICAL LINES...It's worse than the graininess part. These lines should not be here on a $650 phone is really my biggest complaint.
Honestly, it's just a matter of quality control. Some phones are worse than others ??? Well that just proves that it's the QC.
I hope Samsung ups their quality control so people don't get stuck with these visible lines on their $650 phones.

Which is why I call this thread bullcrap. I'm not trying to be some android shrill, but telltale signs like "iPhone is perfect" and "I can tell its pentile" stand out.
No, you can't tell it's pentile (no one has been able to and I doubt he's placed his screen under a microscope).
Maybe you should have bought the iPhone 4 instead.
I thought it was obvious this person is an apple troll. C'mon. Iphone being better with it's 3.5" screen being compared to a true hd amoled that is first gen. Makes the iphone better? Please. Also, you knew you were buying into an early adoption on all kinds of fronts. Get a blackberry and be done with it.

HD Super AMOLED Eyestrain?

Does anyone else experience eyestrain with devices that have the HD Super Amoled screen?
I notice after about 10 - 15 mins of use, I get dizzy and my eyes hurt like they are being crossed or something when using the galaxy s3 or galaxy note, my old galaxy s2 skyrocket doesn't bother me though....
I've tried to turn the brightness down all the way, using the device at different distance to no avail.
Any possible solutions to remedy this? or am I going to have to sell my new S3 like I did my galaxy note? :/
depends on 2 very important factors...
1- how much cheese I've smoked
2- what was the question again?

I've actually noticed a decrease in eye strain coming from an LCD screen on my atrix. LCD screens are constantly flashing, and the screen on my galaxy s3 is super clear for me almost no eye strain. Its probably personal preference though.

I've actually experienced the opposite as my first android device was an atrix....
I think it may have something to do with the 1200 x 800 resolution on such a small screen because If I turn up the resolution on my PC HD monitor to something like 1600 x 1200 for example, my eyes start to hurt.
I was actually going to post a new great until I saw this. I came from retina displays and my eyes are sore after I look at the screen for over 10 minutes on my GS3. Kinda concerning!! Might have to switch back to an apple product. I was getting use to droid too. :-/
its because of the screen size/pixels. Your eyes still needs to be adjusted to the new screen lol... obv
Yes!
I got vertigo/migraines about a month after getting my S3. I had a number of medical tests to see what was causing it - but even after new glasses I've narrowed it down to the S3 display being too strong for my eyes. I'm going to sell mine and get a replacement with a duller screen.
Try this...
Try changing the Screen Mode to 'Natural' or 'Movie". Helped a bit.
I also immidiately noticed eye fatique after getting Galaxy s3, particularly in my right eye. It started only getting worse, and coincidently only when I was using Galaxy. Other lcd devices such as older 3gs never bothered me at all. Surpisingly majority of reviews call the display stunning quality, but its pretty dim, practically unusable outside and colors are unnaturally oversaturated, all of which didnt bother me that much as long as my eyes wouldnt hurt so much. I started reading more about specs in Super amoled technology, but nothing pointed out to potensial issues, than I googled galaxy s3 refresh rate, and the first video from the search result comparing s3 to the iphone, provided a major clue. The poor quality camera was picking up horrible flickering from galaxy, but iphone screen didnt flicker at all. It instantly brought me back to old CRT days, and I also remember getting dizzy from such displays running at low refresh rates of 60mhz. Back than bumping up refresh rate to 75mhz conciderably dicreased eye strain. I took the video to the store, sales person was suprised that I was returning such popular product, but its been a day since my exchange for another brand and eye strain is gone. The issue maybe overlooked as it affects low percentage of people, but if you have sensitive vision, than you'd be much better off with non hd amoled technology
Could it be the brightness?
I'm sure your not holding it against your nose while watchin you tube, but maybe its the overall brightness of the screen thats getting to you? I use a powersaver app that has a black screen filter that dims it out a good little bit, maybe something like that could help, or a matte finish screen protector...the anti glare ones I think.
Use the "Screen Filter" for use at nights.
Set brightness to 0, and enable filter. I set mine at 48.6% and 36.9% (created two widgets with these percentages) and use either as needed.
Set your brightness lower. It's the brightness of your screen. I have the same problem before turning down the screen

Hi all,
There are a lot of users who feel uncomfortable with AMOLED displays (not all of them, for example sgs2 is not affected). They can struggle with head ache and eye strain. You can google "galaxy s3 eye strain" for example or watch how AMOLED blinks through photo/video camera (there are tons of youtube videos). This effect apperars only when screen brightness is not at maximum level. The nature of that is the mechanism used for brightness control. Instead of forcing the pixels to glow at less brightness they force them to blink very fast. The faster pixel blinks - the brighter it seems to the user. The downside of this is that the whole screen blinks as an old CRT monitor which causes this negative effect.
I found an app which could help us to workaround this issue. I filed a feature request. So if you are interested you can add yourself to wathcher list and post a comment here - https://bitbucket.org/VitoCassisi/lux/issue/38/lux-auto-brightness-feature-request-for
This should not take a lot of time since you can authorise there with your google/facebook/twitter or other account.
Wow! I switched the screen to "natural", the problem with oversaturared, too rich colors was solved. I had to keep the brightness low so color pictures aren't too bright, but this made reading text on white backround unpleasant. Of course now I have to find new brightness levels (what brightness levels do you guys use for day and night?)
PS: Samsung has been doing similar tricks with the colors in their TVs. Some series 6 TVs made the picture look like it was from a heat sensor in dynsmic mode, and this was their default mode.
PPS: Mobile screens suck. LCDs have washed out blacks which strains the eyes, and AMOLEDs don't care about correct colors which makes you duzzy.

You are absolutely right. S3 screen flickers a lot. Try to move it quickly in front of your eyes, move your eyest when looking at it, or move your finger fast in front of the screen. I certainly do notice it.
What other phones have better displays? Sony? HTC?
I have a solution to resolve galaxy S3 scren flickering: set brightness to max in settings, install an app like "Screen Filter" (one with black-white rectangle) and decrease brightness there, in the app.
Flickering gone!

Most of phone LCD screens are not affected by flicker. Even some amoled displays too. For example old HTC Legend and galaxy S2.
Galaxy note 3, 4, Galaxy s4, 5 are also affected. I strongly recommend you not to buy any new samsung phones equipped with AMOLED screens.
Now with this https://play.google.com/store/apps/details?id=com.vito.lux software you can get rid of screen flickering issue. Automatic brightness adjust will also work.

[Q] Note 2 - Comfortable Reading?

I am planning to buy Note 2 in close future, and i wanted то ask Note 2 users, that read books on it.
Is it comfortable?
Is the Amoled screen is better or worse for reading than ips?
What is the overall feeling of Note 2 as reader?
I want to use Note 2 heavily for reading, that why i need that info.
Thank you.
I do a lot of reading on my Note II. Not so much books but news! The display dpi lends itself well to reading as does the smart stay feature. I have my screen of set to 15 seconds yet have never had the screen switch off whilst viewing. It was a feature I first thought was a gimmick but it really is very very good. The only problem is if you read at night with no ambient lighting. Then it cannot see that you are reading and may turn off.

normally i'd say an LCD display is better for book reading.
when an amoled screen is forced to display white, it consumes more than twice the amount of power compared to an LCD screen rendering white, simply due to the way amoled works. so amoled will drain the battery faster if youre reading black text on white backgrounds.
but if you invert it to white text on black backgrounds, you'll get much better battery life.

I know that Amoled consumes more power on white, but Note 2 has a monster battery - so that isn’t a problem. I am taking about reading quality in 4 variants:
Reading news in browser,
Reading books in daylight -black on white,
Reading books at night - green on black,
Reading pdf and djvu books with lot of diagrams and pictures.
(I know that for pdf tablet is better, but i want something compact.)

I bought note ii for the same reasons and I am not regretting.
I read news/forums a lot on GN2 and it's been fine, no eye strain even with black text on white background. I do recommend Screen Filter app and set auto brightness with auto tone turned on. You can even turn on negative screen colour rendering in accessibility options.
The screen size of this phone is a big plus for reading, however I do make the text larger than the default for easier viewing at distance. Remember don't read too close to the screen...

I use my note2 daily for reading daily. I switched from the fairly large screen s3 but its a huge difference. s3 was fine for occasional reading but note 2 can totally replace an eBook reader or tablet.
I would say that the Note2 is He best phone for reading simply due to its sheer size. Its only slight smaller than a standard book, so you can display text at standard book font size (publishers tend to use very similar sizes across the board) but not have to keep scrolling excessively like on smaller phones.
Using a reader which properly renders white text on TrueBlack (like Pocket), lets you use a lower the brightness than you normally would, due to the high contrast. I find this greatly reduces eyestrain compared to an lcd.
Black text on white background is pretty good as well, in part due to a setting called Auto Adjust Screen Tone (AAST) . This saves power by reducing the tones of brighter colours and has the side effect of reducing eye strain.
Also don't want to under estimate the battery life.
On a full charge, I get about 7 hours of screen time for purely reading Black text on white back. However white text on black lasts a whopping 13 hours. Video playback is usually between 7-9 hours.

Thank you all for your reply. Finally bought the Note 2. For now, I am very pleased by the screen quality. Overall impression is just incredible. There are so many things in that device! I am feeling "little" overwhelmed by that pho... tab... phab.... thing. About reading - feeling very good after 30 minutes reading. No comparison with my LG P500 LCD screen. Screen is not as bright as LCD, but with much better readability. Feeling it little like e-ink display... Will see how it will feel after more reading.
My brother just upgraded from an iPhone 4 to a note 2 purely for reading. He was always saying the iPhone is fine for ebooks but once he used the note he could never go back haha.
Tl;Dr note 2 is great for reading

I was reading fine even on my Zoolander phone called Vibrant, this phone is much easier on the eyes. You'll love it.
You can use an app called screen filter to bring down the brightness even more to make it more comfortable especially in a dark room

I bought Samsung Galaxy Note 2 just a few weeks ago, and because I'm an avid reader I'm immediately downloaded from Google Play store all major readers in the market such as Kindle, Kobo, Aldiko Premium, and UB Reader. I was reading e-books when I have Nokia E71 with just 2.4 inch screen! And by the way, I do not remember when was the last time I read a printed version of book. It's the past. So, you can imagine what the reading is when you have Note 2 with 5.5 inch screen. It's just an awesome experience. However, I went to Settings + Display +Screen mode + and chose 'Natural' instead of 'Standart' and I'm thinking about switching to Sepia in my reader instead of those white-black or vice versa. It looks like it is easier for your eyes but I'm not sure about that. Maybe others will tell me if reading on Sepia is healthier for your eyes than on sheer white?
Use night mode. ..white words on black background. ..is less Stressful and also saves battery on amoled screens

Brightness Uniformity of Note 2 Display.

When you go into LCD Test (*#0*#), I notice that the brightness is not really all that uniform on the display. If I bring the device close to my face I see the brightness as same and when I extend the phone further away from I can see a little difference of brightness (very minute difference; extremely hard to tell unless you play with the different brightness modes). To appreciate the difference you need to squint your eyes. Am I trying to be too nit-picky?
Okay, my eyes are playing with me; just washed my eyes and everything looks normal, what AMOLED should look like, early mornings, lol :silly:

yeah seems you're trying really hard to find any imperfections. "extremely hard to tell, play with brightness modes, squint eyes etc"
should i do this under a full moon or candle light?
i usually stay away from these threads but just found all the conditions you mentioned funny. just use your phone under normal conditions. i havent noticed a single flaw... cause im not looking & digging for them.
you have three threds open discussing screens, mura & audio problems... seems like maybe you're trying to convince yourself or others about something?
EDIT: Four threads.... Refurbished phone
Perhaps, I know I paid too much, and finding flaw's like these shouldn't be so easy. I mean, I've been through '3' Note 2 already, currently on my 3rd Note 2, and am I trying to mend my relationship with the Samsung Company, especially after facing more or less similar experiences on the S2 and Note 1. I know my AMOLED display is fine, but physical things like chrome-paint finish, and elevated home button are things I really hoped Samsung would improve their quality-control on; pretty soon, they will loose business as a result of this. I made threads not only to share my insight, but to also have an open discussion about everything I have come across with the Note 2. Not surprising, many have seemed to confirm the same things that I see. So, I'm just joining the bandwagon and moving along. :good:
I think I'm going blind because im very satisfied with screen on my note or maybe I'm not that picky. I be happy if it last next 2-3 years or until my next impuls buy.

Does the screen hurt anyone else's eyes?

I feel like the screen from my new note makes my eyes ache and get blurry after extended use. Does anyone else have this experience? I am wondering if it is the WQXGA LCD screen that is doing it. I didn't have eye strain with my last tab, the asus tf101, which admittedly had a much lower resolution IPS screen. I also didn't notice eye strain for the short time I had the tf700, another asus with an IPS screen which I ended up returning for the note. So maybe IPS screens are better for me.
I tried reducing the brightness on the note and have it in movie mode but I still notice the pain. I am not sure if this pain will go away after time or I am imagining it.
If anyone has any experience with this I would appreciate hearing about it.
Thanks very much in advance.
So is my first time with a touch device, and with this resolution. I didnt experienced that... I am pretty sure that is only you: (or maybe, you just need vitamins )
I dont have any medical problems in my eyes, I dont need glasses... I never experienced something like that (just something weird in my fingers) but actually my boyfriend does...
He feels the same as you... But in this case, his problem is different... After a long time with the same problem, he experienced random nosebleed's... Like pression. The only thing that helped him is just the use of eyeglasses. But maybe is not the same thing, so dont worry, im just saying my opinion.
What else do you feel? Surely your eyes got tired, or you just need glasses for that. Something else that you want to say? Greetings! (And sorry for my bad english.)

Your Note probably has smaller text than the other tablets. Now your eyes are straining to see the smaller text.
The cheap solution is Drugstore reading glasses, which may or may not help you.
The best solution is a visit to your optometrist. It happens to most of us. :cyclops:
Thanks for the replies. I have used other 10 inch tablets and I have not had a problem with them. Why would the text be smaller on the Note if I am looking at the same web page in Chrome, for example, at the same zoom level as another 10 inch tab like the transformer tf101 or tf700?

The higher the resolution, the smaller the "default" font.
A 10" 800 x 600 screen will use a larger font, while a 10" 1920 x 1080 can take advantage of the resolution by using a smaller font.
The normal eye can make out smaller text if it's "clear". Lower resolution screens have fuzzier text.
The Note's 1920 x 1080 screen is the "clearest" on the market, beating the Apple by a wide margin. Any other 10" tablet you look at will be less clear than the Note.
The only thing that hurts my eyes are reading all these stupid complaints about this tablet. This has got to be the most idiotic thing I have ever heard. Take vitamins, get glasses and get Laid..

No need to be rude. This guy has a legitimate question. Sorry if it's not up to your forum standards, but this is the Q&A forum and he had a Q. No need to be a douche bag about it.
I had the same problem. Two things helped
1. Got an app named Lux from Play Store. Excellent for reducing eye strain especially at night.
2. Installed a screen cover - matte anti reflective. Also has the advantage of being fingerprint resistive. Amazon has several brands.S-pen works just fine with it.
I get blurry eyes and what not like @xda-soar mensioned thanks to using the tablet in a dark environment. I didnt even know an app existed that can lower the brightness further (esp in stock Android) so Thanks for that @arbit12 the Lux app is awesome and Thanks @xda-soar for asking the "idiotic" ( )question as otherwise I'd probs had never found this app. :thumbup:

If your eyes hurt, yo u are either reading a bright screen in a dark room, or you need new glasses. The tablet isn't the culprit, eye strain is. I have no issue with the screen at all, and I use it quite a bit.

I'm not blaming the screen as such but I find it doesnt go as dim as I'd like at times when I use it in a relatively dark room. I'm used to using my laptop at a very very low brightness setting.
During the day however I never have any problems with it, so it is just a night thing for me but anyways with the Lux app now installed on the tablet all is well.

If that hurts, why don't you stop reading and close the page :fingers-crossed:
Or this comments helps in anything with the post
Actually any Samsung AMOLED hurts my eyes, too. I think it is not problem with most people.
I and my wife are facing the same issue of eye strain , this is not after prolonged usage , within 2 mins , eye strain starts while using regularly , there is no strain whenever j use my iPhone and my friend's ipad
Yes!! I found your question when I googled the same question. My eyes are blurry for at least 10 minutes after using my S7. My old phone’s, iPads, don’t do this.. and I’m on low brightness and night mode.. it still does it. I needed to buy glasses shortly after I got the phone. I am at the age for it, but the eye strain and pain is seriously ooonly after every use of my phone. I don’t even want to check my messages any more. Ouchies!

I have just got the new note 10 phone and experiencing the same thing.... never had problems with my eyes beforehand, since this phone!
For all those posting negative snotty comments.. get a life... why are you even here to comment if you have nothing good to say?
Have you got a new device? How are your eyes now
Old topic but:
- IPS/LCD is usually less stressful on the eye (as there is no pwm flickering on <100% brightness) compared to OLED.
- Notebookcheck usually tests for PWM/flicker in their reviews. Also see: http://forum.tabletpcreview.com/threads/flicker-free-tablets.64302/
I would say.. the Note 2014 is fine, but it will never be as good as an e-reader screen - in terms of like eye friendliness.
For me, I did have some eye strain with this device when I was using it for hardcore note taking. But I think it only happened because I was so focused on taking notes, and trying to make them look good and whatnot that I didn't blink often enough. My relative used this tablet for a few years - and now it's back to me. Used it like all day long and never complained about eye strain. So I am certain it was on me.
I feel strain when I look at it in the dark to unlock. Apparently due to facial recognition, the brightness goes full to emit light and brighten the face for recognition.unfortunately you need to leave eyes open for it to unlock or see what you are typing. Switching off facial recognition and turning on blue filter fixed it for me.
