Will using Black background,drain battery less than using white background?
White background produces more light hence more drain...
Any thoughts...
Huh? you mean having a black wallpaper?
yep..you got it right..

Blackle
This sounds like the old Blackle instead of Google argument. Black does not save battery energy on an LCD monitor, of it it does its negligible. If the LCD is on, the backlight is on regardless of the colour displayed.
"The Roberson study found that LCD monitors saved up to 3W by switching from a white to a black screen, and in no case did any of the LCD monitors use more energy displaying black than white. "
The old CRT monitors save energy displaying black, but it is widely thought that LCD monitors do not.

All I have to say is...
"You know the rules, and SO DO I!"
I have been using a black Google at bGoog.com to get a better battery life on my phone and to reduce my data usage. On OLED based screens you can use over 4x less power having a black background instead of white! The idea that black screens don't save anybody power is out of date and does not account for all the OLED screens that are growing fast in popularity and now in use. There is more info on this at bGoog.com/about
Doesn't the backlight produce the light? It's is on as bright as it is regardless of color in the background. The background color is what it is regardless of the backlight.

What you are thinking about only applies to LCDs from what I understand. CRT, Plasma and AMOLED screens don't have a backlight. Here's an article on AMOLED that explains it: en.wikipedia.org/wiki/Active-matrix_OLED

Why, hello there!
With the Cali sun rendering my Droid almost impossible to browse I come to XDA to seek advice on possible solutions to make the ability to see the screen even marginally better! (Bar a anti-glare shield) Heard there are some possible tweaks on brightening the screen beyond it's apparent '100%' brightness but am curious if this is just positive thinking?
I have been hunting on forums for tips and tricks but to no feasible avail and, 'go in the shade' falls short of answering my question!
So is there any new developments on this or is it not possible to brighten the screen to browse on a sunny day?
Much appreciated!
~L*xo
Are you rooted? If so go to the Market and download Adjbrightness app, it is free and lets you turn the screen display brightness to its Max or any other preset or custom brightness you like. You can also turn off the backlight on the touch keys. If you aren't rooted try auto setting in the display options or try an on screen widget such as the power bar widget that is stock loaded on the Droid1. Long press the homescreen, choose widget, powerbar. Hope this helped.
Thank you for Your reply!
I don't think I worded my question properly.. I meant brightening the screen beyond using an app that can adjust the brightness (I have mine set to 100% in the sun and 0% at night!)
I was hoping there was a further tweak to get the screen even brighter to browse when the sun is glarong down...if that is even possible?
Thank you so much!
.......Ohh and yes I'm rooted (LithiumMod)

Hi guys!
Sorry, its another screen thread. However, Im not enquiring about the screen blackness. Im looking to find out if there is a way to make the background a brighter/crisper white? I notice this when surfing on Goolge or emailing where the background is mainly white.
I never had this problem with my GS1, but the Notes white seems to be dull, like egg shell white.
Any apps or setting to improve this? Thanks!
Part of the whole screen lottery process, some units produce better whites that others.
Or you can goto the settings and under display disable automatic power saving something for the screen, it allows whites to go full blast at the current brightness level.
The stock browser also dims the screen (by default IIRC).
More light == less battery!

Hi, I love my Xperia T but there is one thing that bothers me. I noticed that every xperia T has that automatic screen dimming when viewing darker media on your screen. For example, when i turn on facebook app, before the actual app opens there is dark grey screen. During that sequence screen gets darker, and when white facebook page pops up you can actually see screen adjusting its brightness to higher "normal" level. That really bothers me especially when gaming. On dark sequences screen gets really dark, and than it takes second or two to adjust normal brightness when brighter sequences appear. You can actually see brightness going down when darker images are displayed, and then back up again when brighter images appear.
So I'm not talking about dimming when overheating or flickering (that second is fixed by jellybean update as I noticed), or etc. And before you ask me I if turned on autobrightness in display settings, it has nothing to do with that.
My question is, is there a way to turn this off because it is really annoying?

Can you read my last sentence before question, please? It has apsolutely nothing to do with that. "Adopt to light conditions" means adopt to light conditions in your sourrounding, not in your screen light conditions.

All i thought it differs to auto brightness thats why i ask it sir. Sorry for the question then
You dont have to apologise. So, the problem is that when you watch darker images, or videos, or just any darker screen on your display, contrast and brightness goes down. And when you switch to brighter screen you can actually see, with your naked eye, brightnes going up. I see that Sony intentionally put that feature, but it is very, very stupid one. There is no point in making dark images even darker with even less contrast. I assume they wanted to achieve better black levels that way, or I don't know, but it is very stupid way of doing black levels more black. And, of course, there is no setting in settings menu tu turn this nonsense off, nice one Sony!

This similar annoying ass feature is there in my Spectre laptop. This was supposed to be a battery saving feature and I haven't yet found a way to turn it off. Maybe it's also a way to get higher black levels.
This is the Bravia Engine. Just unselect Settings -> Display -> Mobile Bravia Engine

Dude, this is definitely not a battery saving mode. There is no need for batery saving mode when displaying dark screen, and the problem occurs when displaying dark images or any other dark media, app or non-app. every single time.

OMG... Mobile bravia engine has apsolutely nothing to do with with that, because bravia engine works only in phones stock apps for viewing videos and pictures, and the effect is not even similiar to screen dimming. It brings more saturated colors and that is all.
Same problem is posted here: http://communities.sonyericsson.com/thread/61560?start=0&tstart=0 and Sony replied "I'm sorry that it has taken so long but I have done some testing now using a later software and I'm not able to replicate the issue that you guys report so I assume it's fixed." It is more than obvious that they like to close their eyes on every single problem that occurs. Thank you Sony for your gorgeous support to your beloved customers. I cant be more sarcastic, of course.

It's not my way, it's the way it is. If one understands what mobile bravia engine is, one could never offered it as a solution to a problem that has nothing to do with it. I'm terribly sorry if I ofended you, and I apologize for my attitude. I'm not mad at you, or anybody else here, I just don't see why would one write something just to be written. I know my T-Rex wery well, and I know there is no "normal" way to turn this dimming crap off, so I posted my question here, and expected that someone of the experts would offer some kind of solution to that. And I got things like "turn automatic brightness off", or "turn mobile bravia engine off" even though I previously mentioned that i tried all that stuff. People are "trying" to "help" me here, and they didn't even read what I've written. I'm really not one of guys that would post a question here just to be posted, I searched the crap out of the internet, and I found apsolutely nothing helpfull. That's why I decided to open this thread, to hear what experts have to say.

My phone is rooted and I can't change those values. Can you explain me how to change this? I went to that system location via root explorer, but i can't do much from that point. If I try to open it in text editor it says that this is read only and can't be changed.
Thanx in advance.

If you are rooted, you need root explorer and mount the directoty as RW, then open in text editor

Thank you guys very much! Changed values, and rebooting my phone...everything is fine now, no more stupid dimming. However...I noticed that color adjusment is still visible when changing from dark screen to colorfull bright one. So the dimming is now definitely gone, but that color adjusment is still visible, like it changes contrast a bit, from worse to better, it is clearly visible. Any ideas about that?
I'm uploading a video I recorded with my webcam to get you a closer look. I'll post a link once it's uploaded.
Video will be live here in a couple of minutes: http://youtu.be/fHozO8zGZ1Y
After I managed to turn off DLS, that auto-contrast thing still remains. If you look closely, you'll se that the blue facebook stripe (and everything else) slightly changes its color/contrast when returning from the gray screen. But DLS was much bigger pain in the ass and I'm very pleased with the result od turning it off.

1. if i makes brightness to zero then also it gives some brightness
2. color combination is not correct
tell me what will be issue
thanks in advance
Azhar
What so u mean that u made the brightness zero.
Did u used the slider bar in the display setting.
If yes then it will not make the screen black as it is not practical.
And what do u mean by the colour combination not correct.

Different phones do different things - doubt it's a bug - you can install screen filter apps to further reduce brightness (I use one for phone use in the dark).
The orange/yellow photos that the camera on this phone takes is a well known feature of the SP...
