AMOLED: Black wallpaper = Battery saved?

[ilh]

100% black background for me too, 1 of the first things I did when I got my Desire. Looks better, saves battery and reduces the need to have the display brightness up as things are easier to see against it saving even more battery.

Do what I did - Google 'black.png' on the phone and use the image off Wikipedia!

It's a tiny file, will save you battery and saves the desktop looking cluttered; I can't stand pictures behind all the icons.

/rockin' 100% black desktop on all my computers & phones since, well, a ZX81 or something I suppose!

I must say, that is an amazing idea!

I was thinking about the hassle of putting one on via my laptop. I'm new to smart phones

To be honest guys, much as i appreciate this interesting read which i quite educative but i must however confess that my phone has WIFI on ALWAYS because i have free WIFI also at work, i browse very often during the day both at home and at work. Though i do not listen to music but i still use the phone considerably during the day. I actually charge my phone daily when i go to bed at nights and by then the level is about 40% left (as i can read in the sticky section about batteries , this is recommended for optimal lithium battery life).
My battery lasts roughly 2

+1 !! i love the nexus one live wallpaper...allways amazes people when they see it

Just remember that a live wallpaper is also very detrimental to your battery life...

Roughly, you will get 1.5% battery saving per 15 minutes if you are using black background compare to the default HTC Desire wallpaper.

Only if you stay on your homescreens for long periods of time

Exactly, and thus people are wasting their time.

What would be useful (and I think I have seen this in some ROMs) is to use a modded browser with white text on black.

On both the Olive Tree Bible program and EReader I have changed the background to black with white letters.

I haven't done a real test but I think my battery use is much less than white background and black letters.

No, AMOLED needs a pixel to be powered all the time, unlike LCD where blacks come from turning the pixel off.

So you'll use the same power, no matter the colour. Only Brightness level will have an effect on battery usage.

You got it backwards.

id love that or at least an app / theme for this forum (where I spend most of my time) that is white on black.

XDA app is great for this.
