The Galaxy Nexus is such a power hog any suggestions on how I can reduce the drain? I've made sure GPS is off and I don't have an active background. Anything else I can try? I loose 30% of battery power when phone is in sleep mode.
Not exactly sure how to turn off NFC.
here's something worth a try, from Francisco Franco, a kernal dev:
"
About the battery I want you people to test this: Reboot your phone, then after it booted up open up Camera, then close it. I think we have the same bug as we had on the NS. Google Talk Video version opens the camera during boot and its sensor gets fired up and since the camera isn't closed the sensor just stays there open in the background wasting battery like there was no tomorrow. Opening and closing the Camera after booting up closes the sensor and then the GN enters in Sleep mode just fine (easy to check with Cpu Spy). If more people can confirm my initial testing then we may "have" found one of the possible battery drains when the phone is idle.

Turning off GPS will have insignificant impact (unless you are USING it in maps etc), turning off WIFI/3G will be significant. Anyway I've recently tried JuiceDefender (free version) and it has helped dramatically so I paid for the "ultimate" version. There are a few issues I need to resolve (likely tweaking its settings) but very happy so far.
The ultimate version does something that Android should have and that is adjustment of the screen brightness while remaining in an automatic mode. All my phones have always been too bright (except outdoors) and I can now adjust it so it is not so bright (and of course save battery that way).
I use Aldiko ebook reader and it had a white background, I have changed to a black background (night mode) as black pixels do not use power.
The phone will give you an idea what is using power overnight, I assume the screen is off so just check first thing in morning which apps have used the juice. It could be something syncing, again JuiceDefender ultimate has a night mode that can turn off the radios overnight.

I've been getting 16 hours of battery life on average lately. This is with G+, wifi and 4g turned on. I had bad battery for a while and finally found the app thst was killing ny battery. It turned out that my exchange account was killing my battery. Once I removed that account my battery significantly improved.
