Make sure anything you have syncing is doing it at a moderate level, when I set up my two email accounts they were set to push and sync every 15 minutes, both are way too much for what I need email for so I set them both to an hour.

Also, changed twitter to only manually sync being that it only takes a couple seconds to due and saves the phone from unnecessarily turning on from sleep.

Don't know if this helps but maybe try turning NFC on if you don't use it?

Disable Facebook contact sync as it doesn't work with 4.0 anyways.

If you can, disable bluetooth, same goes with GPS/Location services.

If you have fancy widgets/beautiful widgets, see how often they update location/weather.

Sorry if it seems like every other point here is just checking what is syncing and what not but when your phone is sleeping those are really the only things that will effect battery life.

Edit: Wiping battery stats has been proven to not do... Well anything.
[Samsung Galaxy Nexus] gogol:
same with me ... using stock 4.0.2 ... drain is about 1% per 2 hours :)
[Samsung Galaxy Nexus] RogerPodacter:
I drain 1% every 2-3 hours. So after 8 hours i'm at 96% overnight. This phone has superb idle drain. This is with wifi connected, 2 gmail accounts synced, 1 calendar, contacts and picasa, gps is on. But i do not have facebook app installed. I am stock 4.0.1 and dont have many apps installed, only what i use.
[Samsung Galaxy Nexus] AndreaCristiano:
mine is great when idle but as soon as I start using it it drops precipitously any ideas or fixes?
[Samsung Galaxy Nexus] miketoasty:
Sadly, lower the screen resolution is probably the easiest way that will notch the best gain in battery life. These screens require a lot of power especially at their brightest settings.

[Samsung Galaxy Nexus] virtualcertainty:
I have the GSM Galaxy Nexus running stock 4.0.1 and I consistently lose 4-5% in 6-8 hours overnight with...

- WIFI on

- 3g/4g on

- GPS on

- bluetooth off

- NFC off

- syncing 2 emails, 2 calendars

- lightflow running LED notification for max 2 hour but on silent (not uncommon for a couple of notification go off during the night)

- beautiful widgets with 1 hour sync

- no effort taken to kill facebook or other backgroung apps.
[Samsung Galaxy Nexus] z06mike:
Try out the new 4.0.4. You're standby drain will go down considerably.
[Samsung Galaxy Nexus] itch808:
OP, are you on a GSM or CDMA Nexus? Are you on 3G only or LTE/3G?
[Samsung Galaxy Nexus] jonathan3579:
Yep. That's about the same exact thing I get on a day-to-day basis with the same settings you mentioned. In addition, I don't think I've ever turned NFC off. So pretty much everything but Bluetooth stays on for me overnight.
[Samsung Galaxy Nexus] NIK516:
Sounds like you may have a wakelock check your awake time com paired to your screen on time , if its considerably more then you may have some apps waking your device. For me it was Google maps so I disabled it for now till the update. I used betterbatterystas to find the wakelock. Now I get 3.5 hours screen on time and under 1% drain per hour
[Samsung Galaxy Nexus] neotekz:
you guys realized that gps and bluetooth do not drain battery unless you are using them so it doesnt matter if they are on. GPS will only turn on when an app needs a lock and bluetooth wont use power unless its transmitting to another device. im not sure about NFC but i would think it works the same way. as long as you dont have anything syncing or losing reception at night then you should only lose about 5 percent in 7-8 hours. this is the case with most android devices that i've own.

Running Milestone 2 with franco 16.2. 400-1000, uv.
[Samsung Galaxy Nexus] virtualcertainty:
There is obviously a vast disparity of results here. I think people need to scrutinize the apps they have installed. I know it is a hassle downloading and customizing everything over again, but a lot could be learned by doing a factory reset, getting a baseline of results, then installing a few apps at a time to see their impact on power consumption while idle.

Just to recount one experience I had: I'm a big winamp user. Loved it on my Desire and installed right away because I love the sync feature from the desktop. However I soon noticed that when that sync is active (ie I have winamp open on my desktop AND the winamp services were running on my Nexus) it was a huge battery hog even when inactive. Even if I only close the desktop application and left the sync running on my phone there was no noticeable power drain, but the two together did lots of damage. I only picked it up because it showed up in battery stats as media server. But if it was an app that used system resources then it would be hidden in Android OS. One app not yet optimized for ICS would cost me an extra 10% per night.

I'm currently at 5% battery loss per night. If I take the time to turn off GPS then it is only 4% because google maps doesn't get busy with passing satellites. Ask yourself what your apps are doing.

I'm running completely stock 4.0.4. Battery drain is very minimal when idle and connected to Wi-Fi. Never really have it idle connected to anything else other than Wi-Fi.

Picture is just a small example I took this morning. As you can see, it's pretty much flat line. I have posted other examples on different threads.
[Samsung Galaxy Nexus] Jules.Winnfield:
Google plus was killing it for me. With it disabled, I lose about 0.5 percent per hour. I do not have Facebook installed either and disabled other apps that I do not use like wallet, current, etc.). Other notifications are all push.
[Samsung Galaxy Nexus] RogerPodacter:
Thats why i think there is something weird with the lte version.

Btw last night had my best yet. Lost 3% over 9 hours with all my syncing going and wifi on.

Well today I downloaded the latest lean kernel and leantweaks.zip and am currently running the preferred voltage and tweaks. I notice a definite boost and slow drain in battery life. It's only day one but I feel the difference in sleep and using my device. Normally would wake up and my phone would be dead. I'm still running on more than half of my battery life so that is definitely a plus.

Here is a screen of the app for those who aren't familiar. Been hearing good things about it and decided to give it a test run.

This is STOCK BATTERY.

Nfc off

Wifi on

Power control enabled

[Samsung Galaxy Nexus] jhericurls:
I'm always flashing new Kernels so its difficult for to get a steady avg idle time.

But I normally can't get less that 1% per hour drain with sync and wi-fi on. With mobile data on its slightly higher drain.

I think I've already tweaked my phone as far as it can go. I only get a single Wakelock during almost 8 hours of deep sleep. Not sure what else I can do apart from put it in Airplane mode, to get better battery.

I'm using Switchpro widget to automate my data & sync to switch off during the night and back on during the day.

Btw OP, idk if that's you in your dp, but if it is you're beautiful.
[Samsung Galaxy Nexus] patt2k:
how the hell do you guys get such good sleep battery? i even use easy battery saver on power saver and i would always lose about 20% overnight (insantly it goes to 98% after un-plugging the charger)
[Samsung Galaxy Nexus] s2d4:
the difference is pbly the level of understanding of how to find unnecessary drains...
[Samsung Galaxy Nexus] MS.:
1% per hour? Mine doesn't eat that much. 3-4% over all night. How do i do that? Hmm, it just works that way. Honestly, i do not care about battery life at all, nor i'm trying to get some better results. Sync (contacts, calendar, weather, Tweetdeck) enabled, WiFi on, mobile data on, screen brightness on auto.

ROM and kernel can be seen in my signature, CPU is set 700-1200MHz. I do not wipe battery stats after flashing ROMs as it calibrates itself after two-three charges.
[Samsung Galaxy Nexus] Baguett:
Why not turn off GPS and BT when sleeping? i dont see the pointon having them on. Also you should use 40% screenlight or less.
[Samsung Galaxy Nexus] dvirf:
i also lose about 1% every 2-3 hours at night.

i have AOKP with BT and GPS off, but the WiFi is on.
[Samsung Galaxy Nexus] JFMFT:
Turning off latitude has always been a great improvement for idle battery life. Great suggestion.
[Samsung Galaxy Nexus] ro_explorer:
I have GSM version, apex 1.0.0, franco kernel - standard 1750mAh battery.

The services ON all the time are: HSDPA, autobrightness, wifi, bt, g+, gtalk, gmail and during the work hours (9am-9pm) I have also moxier mail with push sync.

Under the above circumstances I have idle drain of 1% every 2 hours overnight and about 1% per hour during the day (when, of course, the activity on my synced services is more intense).

The situation changes dramatically when I'm actively using the device ... usually I end up having about 16-36 hours battery life, depending heavily of how much I'm using the phone. The screen on time varies between 3H30M and 4H15M.
[Samsung Galaxy Nexus] kangxi:
I have no problems keeping Latitude on and getting great battery drain. It really doesn't drain much battery at all as others are saying. And keeping GPS on all the times had no effect in battery also when it isn't being used.
[Samsung Galaxy Nexus] ogdobber:
your wrong on this one...if an app wakes the phone and it requires location information, and your gps is on, it WILL use more battery than if the gps is off. common sense here

for example in this screen you can see how the gps was turned on multiple times, battery life would've been better. you might not see the results immediately but over the course of the day, battery stats will get it right. gps requires more energy than anything else...
[Samsung Galaxy Nexus] dwang:
5 hours of deep sleep and still at 100%.

Lean kernel 1.10exp2, gsm gn.

All sync enabled.
[Samsung Galaxy Nexus] RogerPodacter:
Honestly its the difference between the gsm and lte version. The gsm just gets good idle while the lte has something wrong with it is what it seems. I get this great idle on complete stock 4.0.1.

There is no reason to turn off gps. If no app is using gps then it is completely off using literally zero power. Only when you see the gps icon in your status bar is when the gps is on. So turning gps off is a complete waste of time and nusance having to manually turn it back on all the time.
[Samsung Galaxy Nexus] Baguett:
ah, had a suspicion about that, but was not sure. what about if i tick the box above the gps "google positio service", will it drain battery or will it only be active when apps uses it too?
[Samsung Galaxy Nexus] opensourcefan:
Last night I went down 5% in 8 hours, very close to only 4%. From hour 8 to 9.5 I lost another 2%.

[Samsung Galaxy Nexus] ogdobber:
I would think you would know this by now. if your gps is on and your screen is off,,,how are you going to see an icon?

for example, lets say I have latitude and genie widget syncing (there are a ton of apps out there that use location based services but these are the ones I use) anyways, both of these apps will wake the phone to update and when they do, the gps radio will turn on if enabled (and use more battery)...

I guess another solution is NOT to have these apps sync and when you go to the app it can update then...but I don't like to wait, and the accuracy that the gps provides isn't necessary.

another example, if I am searching for something in maps, always cell location is good enough to determine my location...I might search around for a significant time and if the gps was on, it would make a noticable hit on the battery. If I decide i want to navigate to the result, I will just pull down the notification bar and easily enable gps there.

I get you grief having to go into settings/location to turn it on... but I guess that is why I prefer roms with better/more options- aokp
[Samsung Galaxy Nexus] RogerPodacter:
Well sure, but for me personally i know i have no apps setup to wake the gps. And this can be confirmed anyway in the battery graph at the gps line. You should see blips of gps there when it comes on.

One of my biggest problems with battery life was the Exchange client. I would consistently lose 20% on idle overnight, and it drove me crazy. I explored lots of wakelocks, and decided to just try migrating to Google Apps for one account and POW, my battery was getting the incredible idle drain.

[Samsung Galaxy Nexus] JoeSyr:
I'm extrapolating this from real use (albeit light use since last charge), but my phone has been off the charger for ~29 hours, it's currently at 53%, and screen is at 36%. I figure that means raw screen draw has been (.36*.47=~.17). So 17% of my battery was eaten by the screen today. Adding that back in, my phone drained only 30% from everything that wasn't the screen itself (some texting, used facebook a bit, fiddled with some phone settings here and there).

Over 29 hours and throwing it a little wiggle room for the power used to process what I was doing when the screen was on, that's pretty close to 1% battery drain while being inactive. (Screen on time was about 80min by current count, sticking to rough estimates, ~28hours of idle time for ~30% drain).

This is on 4.0.4 (the one rom just about everyone on 4.0.4 seems to run), stock kernel, CDMA w/ LTE off, good reception, wifi on most of that time, 2100mAh battery. I've gone to pretty far lengths to make sure apps I don't want aren't running in the background, and my awake vs screen on finally looks reasonable.

Pretty happy with this level of battery life! This is my first smartphone and while I do like being able to use various apps and access the internet on the go, I still miss my old phone that finally broke, but let me go all week without charging it, using it mostly to text people and make the occasional call. I think this is as close to that as I'm going to come on this phone, unless they really crank out better battery in future updates. Or maybe I'll go down the rabbit hole of kernels next.

I'll append this with some screenshots I just took in the morning.
[Samsung Galaxy Nexus] MilkPudding:
If you want to save battery, turn ON wifi and keep it ON. Wifi uses much less battery than 4G/3G unless the signal is weak and your phone is constantly searching and connecting to it.

Turn off auto-sync. It drains battery no matter what device you are on.

All the videos and directions I saw said do NOT apply in clockwise OR counter-clockwise... Only apply in ONE direction, up to down, down to up, left to right, right to left.... no circles...

I think they might have pushed this to market a little quick and might be getting their PR and documentation a little mixed up.

The emergence of another product with similar performance makes me wonder if we are seeing the next "wet-apply" style revolution. Someone figured out the next best thing and this is the beginning of the new trend :)
