i know this may sound boring but
google "black wallpaper" pick whichever link, dont even dowload just long press the image and set is as wallpaper.
It saves you a TON of battery that and having the brightness of the phone turned off completely ( unless you're using it outside and the sun isnt letting you see properly)
i play alot with the phone, text and when i do talk its 30min or more. i unplugg the phone around 7:30ish and it can literally last me till 9pm. thats my experience. I have a solid black background which made a huge difference.
Also i try to minimize the necessity of widgets that run in the background. ( that battery widget is one of em)

um did you turn on and off your phone after putting the black wallpaper? cuz mine hovers around 12% most of the time ( i toggle the brightness off and on my phone thus the 12% goobling of my battery)
the battery use tab keeps a record from when the phone is switched on. so if your phone has been switched on since yesterday and it was until recently that you switched the background well the difference is not gonna show up (in my experience of observation)
You mentioned you were at work... does your phone have a good cell signal in there? because THAT really drains the battery... the constant search of 3g ( and 4G if you have that turned on) in an area where the signal is scarce
Also have you tried shutting off all background apps through manage apps tab? like music and the browser? google maps too! they do tend to stay on lurking in the background.

The you should definitely hit the stop process on .com.android.settings
you have a virus on your phone
JUST KIDDING!!!!!!!! Wow 14mb?! are you sure it's not 1.4mb? ( mine is 1.9mb)
if its 14mb then something is def not right ... your phone is overhauling that process way too much >.> Try turning on and off your phone to see if you can reset it if that dont work i'd go to sprint... you're still well within the 30 days.

Actually AMOLED registering 58% on the battery use seems pretty normal for that screen type. I don't think it's actually wasting battery but it is what uses the most power relative to the other things on your device.
My battery has last for 4h 38m today and is about dead. Display is at 31%, Google Voice is at 26%, Calls at 16% and Android OS at 9%. I'm getting terrible life with it right now and usually my display hovers around 40-50%. Not sure what the deal is.

When checking the battery widget, it is indicating that the display is eating roughly 58% of the battery.
I know this isn't normal. Any ideas?
Your phone is new and you're playing with it a lot, so the display will eat more battery power. Once you start getting acclimated and bored, the display consumption will go down.
Earlier today at work my display was at 9%, but Pandora was at 47%.
Tonight I was tinkering, surfing and watching Netflix on my phone, so the display is now at 61%.
the battery % is based off a whole, 100% of what has drained the battery, if the display is the most consuming bit for you then the only advice for you is to shut the screen off more often.. :P

I got a program on my phone called JuiceDefender a few days ago. Since I've only been using it for a few days, I can't yet swear up and down that it's the best thing ever, but it does appear to be leading towards that. I have it set up so that if the screens off, 3G/4G/Wifi are all off. Even when I'm using a radio, it determines which radio is the best for the situation and disables the other 2. When I'm using an app that doesn't need the radio (as defined by me), it shuts off the radios. Basically, I've only got the radio on when I need it on, the rest of the time it's automatically off. According to JuiceDefender, it has improved by battery by 42% and I'd believe it.
About the black background. Why would that help? Just because the screen's darker? I don't claim to understand screens, but if that's the case, could we have something like this:

It's still real dark, so you have that, and it's more interesting to look at than a pure black background.
The theory behind a black background on an amoled display saving juice is because of how OLED works, there is no backlight and only the pixels that are displayed are being lit. So on an LCD displaying a black background and nothing else on the screen, when the screen is on it still has the backlight on using power. On an amoled display, that same all black background with nothing else on it would consume no power even when you had the screen on.
Of course, one would have widgets and/or icons on the screen so it would use some juice but just be more efficient if the rest of the screen was black.
I looked into how OLED displays work, and it looks like you're right. It just shuts off the pixels that don't need to be on. That's pretty cool. I'll see how much a 100% background seems to matter. I might just get a cool background and accept that I've got a LITTLE less battery life.

And when the MTSO has an inbound voice call for you, how does it transpond with your phone when the radios are all off??? Or a text message?
I'm the last one to trick out a phone with active wallpapers and constant Twitter and Facebook updates and all that, but fer chrissakes you got a smart phone, it stands to reason that you'd use at least *some* of its features. Or maybe strap a car battery on your belt to power the thing and a liquid nitrogen cooling system for the processor?
Do they still sell plain Jane voice-only flip-phones?

MTSO? If I get a voicemail or SMS, I still get it instantly. Those features are part of the standard cellphone radio, 3G/4G/Wifi are ONLY used for data. So those are still enabled 100% of the time. If, for example, you were using IM+ to talk with people through text and you didn't tell JuiceDefender to keep a radio on when that application is open, you wouldn't get your messages until you turned the screen on. Either that or it would just straight sign you out. I'm not sure, but that's because that uses data. I haven't been hindered AT ALL by using this program. It functions 100% as a phone when the screen's off, the radio stays on when I'm listening to Pandora(or any other apps I've configured), and shuts off the radio automatically when I don't need it.
Either way, after a few more days of messing around with JuiceDefender, I can now swear to this program. It has increased my battery life by a substantial amount. (Note that I'm also using a plain black background and manually adjusting the screen brightness)
Yeah, they still sell those. My dad got one a few weeks back. :P
I think they're all pretty sweet looking. (Yeah, I realize they're all the same, but they're different resolutions! :P)
great - do 'blackish' ones get the same desired affect- i'd assume the darker the better so if not completely black it would still be better than a colorful one, correct?
That's what I was thinking at first, but the according to gabbott and other parts of the internet, no. Pure black shuts off the pixel completely, dark grey still displays dark grey.
EDIT: Also, I wasn't completely convinced that the background was 100% black, so I decided to make one. That way I KNOW it's 100% black and the right resolution. Here's a QR code for the "ideal" wallpaper for the Nexus S 4G.

I'm putting my android to the ultimate battery life test st the moment. I have been at the IRS for just over 2 hours. I have been playing music and using it constantly. I still have 52% left on my battery. If I continue at this rate, my phone will still last me for another 2 hours or so. This is MUCH better than the battery life I was originally getting. It should have already been dead.
My battery saving methods:
Juice Defender - amazing. If you have short battery life, get this.
Black wallpaper - couldn't hurt.
Dim screen - good idea if you don't need it to be bright.

ok, i'm new to the qrcode stuff - i scanned it but now what? i can't seem to figure out how to save the wallpaper
When you scan it, it should take you to a pure black wallpaper that's the right resolution for the Nexus S 4G. Just hold down on it and click Set As Wallpaper.

I made my own by pressing the phone's camera against a few pieces of paper to black out any light from seeping into the camera lens, taking a photo, and making it my wallpaper. Works great, especially as a backdrop for the app icons.

Just tried it to see if it worked well for me, wasn't happy with the results. While it's ALMOST 100% black, if you look closely, you can see some specs on the photo. These specs will have the backlight on.

Get the qr scanner from the market and scan the QR previously posted. Use that background, you will be SHOCKED at how much better it looks than just taking a picture of a black background or blacking out the camera. We tried both and it is a WORLD of difference between the two.

I just pulled the black photo that I took with the phone into Photoshop, painted the entire 2560x1920 pixel rectangle with absolute black, and copied that resulting image to the phone.
I went into a dark room and could see very faint non-black pixels on the edge of the snapped photo, so I set my Photoshopped black image as my wallpaper. The difference did not shock me, but now I am guaranteed all pixels are off on the wallpaper.

I actually like my display power consumption as high as possible. It means I don't have any other useless crap running in the background chewing up my battery, and the display is the one that's using up most of it while it's on. As someone else has mentioned, it's a relative power consumption to other processes, so the fewer processes you run, the higher your display power consumption will be. As soon as I put my phone down and display goes off, that power drain should drop to 0%, and I know there won't be much of anything else draining the battery. I've seen mine as high as 80%.

your display drops to zero? even if i let my phone sit for some time it always seems to be at least in the 40's -typically how many other processes do you show running?

I don't know if it really drops to 0%, I'm just guessing it does because the display is off. Unfortunately, being able to see your display power consumption requires you to turn the display on, so there is no way to see what it actually is while the display is off. Does it make sense?

Just like the question of the ages: When you close your refrigerator door, does the light go off???
So, I'm currently laying in bed and I just noticed something... Go into a room that is as dark as possible while you have a black background. In theory, you should be able to cover up all the non-background pixels and see absolutely no light coming from the screen, however, this doesn't appear to be the case since my screen is still lit a little. Any thoughts on that?
I have also the same problem with my Galaxy Nexus ...just got it before 3 days and since then I am experiencing this problem;more than 50% Battery is consumed by display as showed in settings>battery.
Battery backup is very poor I tried all the recommended things and downloaded Battery saver app also.Still Battery is not lasting more than 14-18 hrs.
Anybody have a permanent solution?
Tried the above solution...phone has been sitting on work desk all day and battery is dwindling down. Widgets gone and wifi off.
Display is still using 56%?!
Anyone else out there experiencing the same problem?
