I have become satisfied with the battery life on my AMOLED inc, but the power button is screwed up so I am getting a new/refurbished one. I am not sure if it will be AMOLED or SLCD, but I am excited either way.
Does the SLCD get the same or better battery life? Is the only other difference between the two that some recoveries don't work with it...
I may be wrong but I've never heard any blaring differences between the two, yet this is with my experiences.
If there is any battery saving difference I haven't noticed any. I got one of the first SLCD units and the battery life is just as bad as before.
For some reason I have it in my head that amoled has better battery with dark colors and lcd with whites. I think I read it in regards to lcd and led tvs.

As far as I know, AMOLED's are better when displaying black colors. Because the pixels don't light up thus saving power. But on the downside when displaying white (Such as a web page) it can use up to 3x more power. The SLCD on the other hand is more neutral. It uses the same power with all colors. Because the blacks light up, but the white doesn't use any more power than the others.
Correct me if I'm wrong. That's just what I've read somewhere along the line.
I think lcd's work by always displaying white then use power to block certain colors out.thus blocking every color, ie black, uses the most. At least that'd what I always thought.

AMOLED on average has better battery life through most tests I've found, but the principles of what you're viewing has a large affect on it. I prefer dark backgrounds as it is, but if you're using a lighter background and have your screen unlocked often it's going to drain a bit more than it would if you had say, a black or dark gray background. The differences are really going to be minimal in everyday usage.
there are several threads for HD2 and desire they are using super amoled screens ... they have mentioned that for super amoled usng black background saves battery ...... cause the pixels are turned off ...
while in case of LCD the pixels are by default turned on .... so if we put black background it actually sucks more juice in case of LCD using Black background . it is advisable to keep white background in case of LCD
Motorola defy neither has LCD and definitely not super amoled screen ......so should we keep black background or white background to save battery ??? i mean ours is Capacitative TFT .... so which on of the case above i mentioned is applicable for motorola defy?
black is prefered, the white one is so dazzle...

LOL, the Defy has a capacitive LCD Touchscreen.
So in theorie it is better to have a white background but
the most saving can be achieved when turning down the backlight.
So it is more important to have good contrasts.

LCD are on all the time when showing black areas or even a full black screen (not the same as being off), unlike OLED choosing a dark background will not save any battery life.
But I have noticed when using dark themes my display consumers less battery.

Makes no difference, lcd backlight is always on regardless of colour.
Just decrease your phone's brightness, it will consume less battery regardless of White/Black background [which may matters but I never experienced such things]

Defy uses a LCD screen, therefore turning all pixels on all the time something is displayed. Even pure black pic
OLED screens however benefit from black backgrounds since a pixel is not turned on until it is commanded to display a color other than black. This results in deeper blacks/higher contrast.
therefore, using a black bg on a lcd screen will not save you power. If you experience otherwise, it's placebo effect
Hi all. Few days ago, i've made a pure black image on my PC and set it as wallpaper on my Gnex. But when i view that photo in gallery (in full screen mod) i realize that screen is not 100% black, it's super strong gray but not black. I'm confuse that the screen is really Super AMOLED or a kind of LCD?
Its superamoled

Although its true that in theory there would be no backlight for an OLED screen, there is still a small amount of current that goes through just below the threshold of on/off for no lag when going from black to something else. Unfortunatly, the tjreshold will not be common for every led, so some leds will be lit. Thats what produces the small backlight even when displaying true black
Its super amoled (or amoled HD or whatever they call it) and is able to produce true black.
Xda dark theme shows no color difference between it and the nav buttons on the bottom.

There is no difference because the soft buttons are part of the display. Turn off the lights and you will see the entire 4.65" display glow a dark grey. It's a bit of a disappointment actually, I have a Samsung focus and galaxy S2 and the displays are BLACK. Side by side you can definitely see the difference, in the dark I cannot even find my Focus, the nexus on the other hand glows bright enough to notice.
You guys need to remember also that this is a PENTILE display, in order to get the 720P res, Samsung went with a pentile display. There is a big difference between the Super AMOLED displays on the other samsung devices and the nexus. The not really pure black blacks is one of the cons of the nexus' pentile display along with a slight yellow hue, viewing angle and a few others covered in many online articles.
Don't get me wrong, the display is still very beautifull in comparioson to most other phones. The resolution is amazing, I played a 4.2GB MKV of Avatar with MX player and it played flawlessly and the full screen (4.65") video was gigantic and absolutely crisp. But it's still not the AMOLED that Samsung customers are used to seeing.
so pentile or not if it displays black all led is turned off and thus dark no?
i understand pentile may affect other color reproduction but true black must be true black coz led is turned off right?
my previous phones were a gs2 and vibrant, blacks are blacks on all of them including this gnex

It's a PenTile Super AMOLED screen. This is as opposed to the Galaxy S II and Droid Charge which use Super AMOLED+ screens-- which use the traditional RGB stripe sub-pixel arrangement.
Looking at the button bar in the dark on my gnex, I can safely say mine is true black.

No. Like the guy before said, there need to be still a low current on the display so that there would be no lag when switching from black to other colors because it takes longer to switch on the display than changing the color.

For some reason these new HD amoled screens aren't showing total black like previous amoled screens. There are already threads we talked about theorizing why this is. Put next to the nexus one or galaxy s and its not as black. Perhaps its due to higher pixel density, or maybe a change in the technology. But you're not alone, just have to live with it.

Put the phone next to a Note and you'll cry foul. Colors, brightness, and everything look like crap when held side-by-side.

I don't get it, since they are using the same screen (except the resolution), shouldn't they be the same?
There are some defective screens out there.
My blacks are black. Not grey, not almost black.
Black.
Is pure dark so important? How often we stare at our phone with a pure dark picture in a pure dark room?

It's more of saving battery. When it's pure dark, the individual OLED's are almost completely turned off. I say almost because some current still runs through it but nothing like what an LCD would.
And it's better for contrast?

The blacks are pretty damn black on my phone, comparing with my gs2 if anything its just as black?

Higher resolution will most likely result in more possible backlight from true black. (Because of the greater amount of leds being over the threshold)
And i cant says my screen is totally absent of any light, but it is damn friggen close.
Any AMOLED screen will beat the crap out of LCDs. The contrast is an order of magnitude higher thanks to the screen generating its own light, thus being able to shut down fully (or almost fully) to provide no light.
Why do you complain that there is a minuscule amount of current going through the current with a barely noticeable in pitch black amount of light being emitted, when any other screen will be VERY noticeable at night when displaying black?! This phone's screen is amazing. Yes, it's not perfect, but it's better than most (all?) other phones' screens out there. You know, screw that, this thing is probably SEVERAL THOUSAND TIMES BETTER THAN THE MONITOR YOU ARE CURRENTLY STARING AT.
I had before Note and it was burninng in! Things like keyboard or status bar, now I'm afraid to use my Note 2 because I don't want to have burn-in things on my screen :/ So will galaxy note 2 burn-in? They said the new screen in Note 2 is non-pentile ,so.. it will be burn-in proof ? (rethorical question)
Sorry For my bad english.
Yes with the time it will have burn-in as all amoled screens.
I had my note 1 for a year and I was worried about the screen being damaged with screen burn. I kept the brightness down to a low to medium level and found no noticable wear on the screen after a year. The brighter and more vibrant your screen settings are set on the faster your screen will suffer.

All AMOLED screens suffer from burn in, it's a matter of when but with caution you can prevent it. My SGS2 with RGB non Pentile suffered from burn in after 11 months, likewise my sisters SGS2.

It will burn in, but I've had my Note 1 for nearly 11 months now and I don't have any burn in, and I keep it on automatic brightness. But I'm sure it's just a matter of time.
My GS2 got bad burn-in from Navigation - I left the screen on all the time when driving.
I am now using a MIUI rom which lets me press the home button 4 times to invert screen colours. I use this on Navigation to try to balance it back out (the lighter middle section of the nav screen is where the burn occurred).
I use lowest btightness and little screen on time and in 6 to 9 mths i noticed it

Ok so this is only my opinion.
This phone is awesome but very expensive. Some buy this phone with a 2 year contract so i think its really bad that screens on phones like this have screens that can burn in within a year.

I had exactly the same experience with my galaxy s and galaxy s2. I always kept the screens at low brightness, and never noticed any burn in. A friend of me who also had an S2 always had his brightness set very high, and at his phone I noticed there was some screen burn in when I looked at it.
So, now I have my note 2, and I am going to keep the brightness at a low level most of the time, so I don't expect any problems.

Preventing AMOLED burn in
I've had the Samsung Moment (AMOLED), Epic 4G (Super AMOLED), and the Epic 4G Touch (Super AMOLED+).
I noticed burn-in on both the Moment and the Epic 4G due to long screen on times and high brightness. I used to leave the screen on during my 45 minute commute so the Pandora Controls and the status bar icons were easy to see on any white backgrounds. With my latest phone I use short screen on times and adjust the brightness as needed (using the status bar slider). I've also switched to dark backgrounds in an attempt to maximize battery life as well as prevent burn in. This phone is currently just over a year old and has no detectable burn in, as checked with a dead pixel app swapping the screen colors between red, green, blue, and white. I've also integrated smart stay to keep the screen on when I need it but shut it off when it's not being looked at.
So, YES! Amoleds will burn in. In order to prevent screen burn-in I suggest this:
Limit unnecessary screen on time ~burn in is directly related to how long the screen is on.
Use the correct brightness for your situation ~burn in is directly related to how bright the screen is.
Use dark vs lighted based themes ~black uses no pixels, can save battery, and prevent eye strain!
Auto-hide the notification bar, or change the time format frequently ~It's the first thing to burn-in since it's visible and in the same location regardless of what app you're running!
Consider using a screen filter app at night for an even dimmer screen ~It'll protect your eyes and your pixels.
To detect screen burn in you can use just about any dead pixel app. Burn in will be most visible when the screen is all WHITE or all BLUE although you may be able to see some burn in in RED or GREEN although those colors are less likely to help detection.
Replacement is the only real solution in order to correct screen burn in. If you replace your phone every year (like I do) it shouldn't be much of an issue for you. However, If you're stuck with your phone for 18-24 months than you should take burn-in prevention seriously!
is the screen replaceable and for how much?

Best would be a warranty repair. Otherwise you have to source the screen + digitizer so price will depend on that, then you'll have to do the teardown/ replace/ reassembly yourself:
This is sad, warranty should cover this, it´s so miserable that you must be this careful about usage of this pricey phone...
How do I Auto-hide the notification bar?
Also, how do I disable UMTS messages from a mobile phone carrier that sends occasional messages to notify the balance I have left on my prepaid card?

If I spend a lot of time with my screen on does the color of the background wallpaper have a measurable effect on battery life? I've heard that a plain black background uses the lowest power. Is it a big enough deal to give up a nice background screen?
I don't think there is much if any difference in battery life based on the background picture. Brightness along with screen time affects this phone more then anything else.

I would assume that a live background would make a difference in battery though. Iv always used a black background since my G1 but thats just because I like it but u could always do a test and see if it does effect battery compared to different colors.

With our AMOLED screens having a darker background actually does help. I was reading up on something where when u have a black pixel, the cpu instead of turning that pixel color black, it shuts off the pixel.... So it should save some power. As for color regarding solely on processor use, id say its very minute and shouldnt effect ur power consumption that much
