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

So I know amoled screens save battery power the darker the backgrounds are. Are the tft screens that the g2 have the same way or is it the exact opposite?
This stirred my curiosity and was hoping one of you could answer this. Thanks guys.

I saw a thread like this on iPD
I think the best is black but someone was arguing white so if not go for grey
Neither is true for traditional lcd screens. The backlighting is ALWAYS on so it doesnt matter what color is being displayed on the screen if im correct
I believe that PURPLE is the best color... No, Im just kiddin I honestly think that this is hogwash and that its all about opinion. I think as long as you do not use a live wallpaper you are good. So Just keep that in mind.
Thanks for feeding my curiosity guys XD
I'm not really worried about battery life. This battery is just about as good as my old MT3G, which was way better than my old G1 and HD2.
Was just curious because I saw review videos of them saying how the battery life will be better with 2.3 on the Nexus S due to it being amoled and having black touches throughout the interface.
Black takes more power to display than white. It has nothing to do with the backlight though. It's only about a 3% power savings though.
What is it that makes an LCD pixel change color? Is it a different frequency or a slight adjustment in voltage that does it? I don't know too much about it but it seems that it would need to be either one of those two right?
Wouldn't that mean that power could be saved if you tried to theme with a color that uses a lower voltage to trigger? Or frequency for that matter..

If that were the case...I believe red would be your best bet... Give it a try and tell us what happens!

Lol. I have been using red actually. I have decent battery life already. Just switched to green, we'll see how that goes.

I've been wondering this to I always had a black wallpaper for my vibrant and I haven't really changed the wallpaper on my g2. I get better battery life if I use the HTC live wallpaper for some reason lol

Since screen consumes a good chunk of the total battery percentage, I've been reading some things on the internet and it seems like people are saying black color theme consumes less battery power than other colored themes, but only on a certain type of LED. If so, does the MT3GS has that type of screen and does black color theme really saves more battery for our phone?
some other odd stuff: first one is what happens when i leave my phone on in a lecture hall for an hour... second one is just my screen going weird.
That is for AMOLED screens and you have to use a mod that uses true blacks and what that is, is instead of using backlit blacks it just doesn't use those pixels and so that increases battery life. (And AMOLED is used on higher end devices so no the MT3GS doesn't have it.)

Ah, thanks very much!
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
I like the effect of negative color.. but I dont know if it drains battery faster or not..
Any information is appreciated

The feature itself does not drain battery more or less, it depends what colors will be on during the screen time. If you look at a mostly white screen then the answer to your question is YES. AMOLED screens only consume power when color is displayed, so everything black on your screen is actually not using any power, white on the other side is reaaally bad for OLED and AMOLED screens, because all subpixels need to be powered. So only by using a black wallpaper you should save some battery life, whether you achieve this by using inverted colors or not does not matter in the end. I also remember reading about blue pixels dying the earliest in AMOLED screens, that was when I was using my Galaxy SII, I don't know if that is still the same for Note II. I used to avoid blue wallpapers etc...
Here is a little info
Not really yeah but it's said dark colours are more battery friendly.
