Noled

Hi
Has anyone tried the NoLed app on SGS2. This is an app that simulates a LED indicator.
The display technology on AMOLED screens is suppose to be highly efficient since each pixel is individual lit. Furthermore, the black areas on the screen are where the individual pixels have been turned off. That is why the Samsung skin makes use of such a lot of black areas.
The idea behind NoLED is that when you have a missed call it will display a small number of lit pixels on the screen….again, because it is an AMOLED screen over 99.9% of the screen can be turned off….so the device should only be using a negligible amount of power.
However, I have noticed that this app consumes a lot more power than it should. If I get a notification during the night I notice that the whole of the screen is very slightly lit….you would not normally notice this….I only did because it was night time.
Furthermore, I have noticed that the graph of the battery usage declines significantly after this point.*
Anyone else got any thoughts?

Have been using it since day 1. I don't see it as a big power drainer. Whether I have notifications or not, I tend to lose 5-10% depending on how much display on time I have.

I have it on for 15 min or so. So it shouldn't drain the battery if I don't check it for a long time like during the night. CM has a great feature/tweak that lets you choose a time that the screen never goes on. Just have to wait a bit longer for it.

[Q] Screen Mode & Battery Consumption

Ok so the Note's got Dynamic, Standard, Natural & Movie screen modes (in order of saturation).
Would a more saturated Screen Mode chew up more battery, because you'd think the OLED would require more power to produce a more vivid/saturated image.
I haven't seen it mentioned/discussed anywhere...It might be worth testing out, although I don't know how much of a difference it would really make...
P.s. I'm not talking about the brightness or backlight at all. We all know that makes a BIG difference.

Saturation of colors should NOT make a big difference. (provided overall brightness is the same)
Let me explain with an example :
Red on full saturation only uses the red leds (at full brightness)
While red on 0 saturation uses all 3 colors at much less brightness

I actually kinda put the same question nobody replied to me aha
It was in Q&A section, I thought I put it in the right place... but If its answered here its fine ^

Didn't know that about the screen. Which mode are you guys using? I always have stuck with dynamic.

TBH from 60% to 100% brightness i see NO noticable diffrence in battery life, on LCD and TFT screens brightness does vary the battery life a lot, but on the note 2 it barely shows any difference especially if most your usage involves dark/black backgrounds

Increase brightness mod?

Hi.
Is there a way to increase brightness of my screen pass 100%?
Ive been searching for apps on the store but nothing.
I can't see anything when I'm outside (san diego) and it's kinda annoying.
Thanks

Nah man.
In the instances where something like that is possible is because of inaccurate maximum brightness levels from the manufacturer in regard to the hardwares highest brightness output and it's realtion to software coded brightness level values
(for battery savings)
which is " unlocked " to allow brighter than usual levels which is still the devices 100% level.
None of this applies to the EVO because 100% brightness is already 100% brightness and not 85%

LCD is a non-emissive display technology. The backlight produces all the light you can have, each pixel's behavior is controlled by filters in front of the backlight that can only reduce the final light output from this initial maximum.
(By comparison, OLED is an emissive technology. Drive the pixel harder, more light comes out.)
So the control you are looking for is the one that controls the backlight.
If you can find a way to make it go brighter than its nominal "100%" brightness level, go for it.
This sounds like a hardware level hack.
Note that perceived brightness does not increase linearly with increased power supplied to the backlight. At the top end of the range, a 10% increase in apparent brightness could cost much, much more than a 10% increase in battery consumption. Do you really want this?

Damn that's true about the battery.i dont really need it all the time just sometimes its pisses me off that i have to ignore notifications cus i cant see ha

What is your preferred brightness level?

Auto is too dim for me so i set it around 79%. Higher brightness hurts my eyes but maybe I just need to get used to it?

I turned off auto and set the brightness to 100%. I love a bright screen. So far 17 hours on battery, 2 hours screen time, and still at 50%. Good enough for me.

I need better

Click to expand...
Click to collapse
Turn off the lights.

I keep it always on 100%. Only when I need to save the battery I lower it.

Would love to get more input.

I simply use auto brightness. Bright screens look better but they strain my eyes too much.

I keep it at 50% and thats super bright for me... Keeping it 100 sounds insane

Apparently I'm in the minority so far. I hate screens that are too bright for the setting they're in. I keep mine at absolute minimum (0%?) unless an increase in ambient light makes it hard to see. Then I increase it as little as possible until it's at similar visibility as it was before the ambient light increase.

i keep mine at 50% also, i could see doing 60% if i really needed it but anything over that would be overkill IMO.

I use auto

auto 100%

I use Lux app. Check the PlayStore and see if it might work for you.

You guys no you can adjust the contrast.

80% most of the time. I adjust when/if I need to.

Usually <50% indoors and >70% outdoors. The best way to make it learn what you like is to use LUX app.

Status Bar Burn in or its normal

I am using note10+ since Sep19 with a factory screen protector. A week ago I have removed the protector.
Now when I observe the status bar area its shade is a bit different than the whole display.
It's not visible easily, you have to observe it strongly to find a difference in the shade of colour.
This difference ends just below the camera module.
So it may also be normal and I have never observed it.
Since my phone warranty is going to end next month I thought to get it repaired if its a screen burn-in.
If you guys can check and confirm from your devices it will be great.

Not normal. Use this apk to detect display anomalies:

OLEDs do not "burn in", that's a CRT phenomenon where the electron beam physically burns the phosphors.
OLEDs have a finite lifespan. As they age their light output weakens.
White puts the most wear and tear of the OLEDs as all 3 c OLED colors are active.
Blue has the shortest lifespan follow by green than red.
The green wavelength is where human vision peak sensitivity is at, so less is more so to speak.
Use black for background whenever possible to increase efficiency and OLED lifespan.
>Keep brightness below 50% when possible<
>Avoid using over 80% and only briefly if so.<
>Keep out of direct sunlight whenever possible.<
Adjusting brightness manually gives you more control, better battery life and less headaches.
