Poor 3G signal will ruin the battery. As well as using that stupid Facebook app. Uninstall it and use the web browser. Also how much screen on time.

Right now it's at 54 mins.
absolutely, that damned facebook app! your screen on time is adout an hour there(it looks like). is your brightness up high or are you using auto brightnes? do you have root, what governor are you using? whats your cpu speed?
Yeah about an hour...... It was at half brightness...... Rooted....... Franco kernel milestone 6........dyninteractive governor....... 230 mhz Min. 1036 mhz max.

try ondemand/deadline sampling rate 15000 up threshold of 98%, or try interactive/sio(i dont use it so cant give you good settings for this combo). if still fine for you, lower the brightness a little more(33%?).
there are a few good posts out on the net about how to save battery life. common talking points would be
Turning off Wi-Fi
Adjust screen brightness
Turn off mobile data when not needed
Turn off Sync for apps that don't need to be always in Sync
Haptic feedback
and many more..
I guess these are the really common ones, so give it a try and see how it works for you
Actually I get way better battery life with wifi on its weird.....if I use mobile data my phone gets hot and my battery just falls!
If you have a VZW Nexus I don't think it's an app, the screen, etc. The wife, the girlfriend, and I all have the Nexus and none of us can make it through the day for the last week or so. The drain is terrible. And we don't all have the same apps installed. I wanna say something's changed about LTE because besides the hardware and Jelly Bean it's the only thing absolutely all three phones have in common. But I have no actual proof, so...
I have the sprint galaxy nexus, and honestly your battery life seems pretty normal if its a CDMA variant. I'd actually consider that to be pretty good battery life considering its a CDMA nexus
Was that with the screen on the entire time? Or mostly idle and screen off? For screen on, that's not that bad. For idle, that's a little off. Me, personally, I only get about 3 hours at below minimum brightness (modified with rom). Try turning down your brightness even more. It should help. The screen is the biggest killer of battery life on the nexus, especially because it's not optimized for it. As well, keep wifi on. Don't turn it off. It'll just waste more battery switching it constantly. Only turn it off if you are going to be using data for an extended period of time. As well, you could try a different kernel. I'd recommend trinity, but it depends on your rom and what features you like.

An hour screen-on, 50% brightness, and the Facebook app can easily chew 33% of your battery... especially if you're on a stock battery.
As an aside, how can you even stand 50% brightness (assuming you're not in bright sunlight)? 50% just seems way too bright. I typically run at 10% brightness indoors, even at work, where we have fairly bright fluorescent lighting.

True that! At first I didn't think the FB app was consuming that much battery, but I tried uninstalling it and the battery statistics have greatly improved. Hope FB gets to fix this soon, it's nice to use facebook through a native app rather than a browser. Don't you think?
Try Fast For Facebook, it doesn't offer as much as the regular app, but it's an app and it doesn't suck up as much juice.

I currently get at least 4 hours of screen time on my GN before it needs charging. I'd use my phone mostly for Netflix, Spotify, Poweramp, ICS+ Browsing. In this run I probably used Netflix for about an hour of the 4 hours of display time (3 episodes of US office on commute to college).
I am using a GN GSM with 2000 mah battery, AOKP Milestone 3, latest leankernel and my display is usually at about 40%.

you know if stock kernel would improve it?
I've gotten 4 hours of screen time with ezekeel's glados gsm kernel on the stock battery. This is with auto brightness, sync on, mostly connected to wifi, not doing anything special to conservative battery. Browsing, youtube, shadowgun, modern combat 3, wordfeud, tapatalk, gtalk.
With the 2000 mah extended battery, I would think you could squeeze out another hour of screen time.

Turn down the display all the way. Disable all mobile networks in the settings. And make sure you keep the battery cool so you dont damage it.

Well 14% onto your 4 hours would only be half of the extra hour needed for 5 hours.
Doesn't pulling data off WiFi consume less battery than 3G?

Wifi uses less battery, but it also depends on your 3g signal. If you have a weak signal then that will use more power than if you have a strong signal.
Why don't u just carry your stock battery in your wallet? Whenever I'm going to be away from a power source for an extended period of time, I'll just carry a spare battery in my wallet and I usually don't worry about battery life. The battery is so small, it easily fits in my wallet.
I'm on aokp milestone 3 with the trinity kernel undervolted and my phone just won't die. As you can see I used it a fair bit with the screen on for about 3.5 hours. So I am very happy with this. O am also on normal battery, nothing extra.

I'm starting to see that looking at battery life, we shouldn't be looking at any number but screen time on.
For me, no matter how long I use my phone. Let that be intense browsing to listening to music, my battery will not die until it reaches near the 2 hour screen on time.
I am trying to figure out if that is low compared to other users. If people can share that would be great.
thanks.
Hour and fourty five to two hours fifteen seem to be about the norm. Some users are getting ~3 hours of screen time with a lot of patience, kernel testing, fine tuning & tweaking as well as careful useage. I think we'll all get there sooner or later. In my opinion kernels can/will get MUCH better for this device. Only time can tell, but I'm not trying to put a show on. If I need my phone, I'm going to use it...whole point in having it.
Most GSM users get around 3 hours screen on time I believe.. I get three on a bad day

Actually both
1.standby
2.and actual phone usage
Standby can be sorted out via removing stupid apps or configs causing large amounts of wakelocks.
Actual screen on time AFAIK can only be done via lowering brightness, or maybe try reducing screen voltage(however, current may increase rendering this mute).
Having a lower dpi screen means less screen touch/input for scrolling so that also helps, it also looks great due to the high res screen (large ppi count).
obviously if you are doing battery intensive stuff like playing games or gps. Not much you can do there.
This is what I'm getting on average , GPS and bt is off everything else on. GSM 4.0.2

That's about my usage, I got two and a half hours yesterday. But I've since changed to Nitroz's Black Exodus so I hope to get more toward the 3-3.5 hour time.
I get between 2 and 2.5 hours with heavy usage on stock battery, GSM version, data on (2G screen off), sync on, AOKP M3 + franco kernel w/ turtle governor, 350/1000 UV. I'm trying gazelle with 700/1350 and I ordered the extended battery off eBay.
If you don't get at least 2 hours screen on with heavy usage (games, internet, etc.), research what is draining the battery.
On an average day I get over 4 hours screen time. A good day sees me hit 5 hours and a long time without charge can reduce this to around 3.5 hours.
I use the official extended GSM battery. Currently running AOKP 21 with Franco Kernel 14.4 undervolted by around -50mV. Auto-Brightness.
Here is an example of my last cycle.
Regards.
Stock everything GSM... Intermittent use of Skype. Wifi always on. Screen at 50%. Google calendar and mail sync.
4.0.1 just under 2 hours.
4.0.2 just over 2 hours and 2.5 hours max.
Average 16 hours without charge
I think it is just as important to post screen brightness as well as time on.
I've not yet tested a lower screen setting and I would be sacrificing its sexiness.
At least 4 hours screen time with:
Version: GSM GNex
ROM: AOKP Milestone 3 (power saver mode off)
Kernel: Lean Kernel
Battery: 2000 mAh
Frequency: 350/1350 InteractiveX
UV: -70 across all
3G/HSPA/LTE: 3G/HSPA and my network doesn't support 2G
What's off: BT, WiFi unless I'm home, Sync for Calender Contacts Browser and Photos.
Daily, I use: Netflix/Poweramp/Spotify/Reddit on my daily commute. Phone/Poweramp/Spotify/Reddit/Browser+ in between commute.
The WiFi is when I got home, and I didn't charge overnight, which explains the long straight line. My brightness is almost always at 40%, sometimes I go 100% if I get home and know I can waste the charge, sometimes it's at 0-10% if in very low light.
Guys, what is the BEST screen ON time you have had? and with What Rom/Kernal combo?
i am SO trying to love my Gnex, but i cant get over 2.5 hours of screen on time. and this is over 3g/wifi with pretty much all syncing off except gmail app.
just looking for more opinions. thanks everyone.
i should also note i am on the Verizon Galaxy nexus...

sorry but, if i'm not wrong the "screen on" define how much you are actively using you device
Honestly, what you are syncing / connectivity won't affect your screen on time much. The Screen is just too battery hungry.
I did get 5+ hours of screen time with AOKP / james bond...but I cheated. Reading books, white text black background.

no i know that, but i just wanted to let everyone know what was set up on my phone. my idle is fine, but if i can increase my screen on time, it would be happy. over WIFI its perfect but using it on 3g, SUCKS it right down bad.
so i would like to see your screen on times, with rom/kernal combos. im on Francos latest now.i was on lean, but it seemed to drain faster
Still haven't got much over 2.5 hours, but I do make a lot of calls and usually my screen on time is more video streaming/gaming so I guess that factors in to the battery life a bit more. AOKP m4/Lean
Sorry, what was the question? the ROM part i understand but what is "Kernal" ?
It also depends on how you use the screen. I'm sure I could get 7 hours all in one shot, but am choked if I don't get 4+ hours over 2 days.
3/4G uses more power than wifi, so you should see more screen on time when connected to a wifi network than on data.
My favourite ROMs: CM9 /w it's stock kernel, or BAMF with Lean kernel. Each ROM has customizable auto-brightness levels; can have a big impact if you use auto frequently.
The below shots are 90% on wifi, the rest on data.

5 hours was mostly from XDA, games and web browsing. I am on a Toro GNex. I limit my syncs to every 15 min, clock 350/1200 hotplugged. And I frequently monitor my wake locks and per app battery drain to insure a healthy battery life and to make sure my device sleeps like a baby. Normally if I'm using the device throughout the day with 4g data on and no wifi, I get 3-4 hours.
***edit: I do have the 2150 mA extended battery. Its not much but it does give a small bump.

Screen on time and battery size?
I get around 2:45 on my GSM Nexus. This is with Bluetooth constantly on and connected to my Bluetooth watch, and also with the screen set to 100% brightness.
Stock ROM and kernel and highest i got was 4.5 hours.

Lol, the system is obviously not resetting itself.....or it was kept on idle (doubtful)...or the dude messing with the phones internal clock. Either way, nice try.
Sent from GNexus w/CM-9 & franco.kernel
This is mine. Mostly Wi-Fi, I keep my screen on auto brightness, that was with AOKP B27 and Imoseyon's v2.5.0 experimental kernel, 230-1200Mhz, HotplugX with the stock battery.
I'd say on average I get anywhere between 4 to 5 hours. I've never gone to 0 battery, usually plug it in around 8 or 9%. Screen is usually auto or 50%, playing games on and off, cruising the store looking for good apps. I also monitor for apps running and kill stray apps.
AOKP with FuguMod kernel.
Hi,
i managed to get my standby drain on unrooted stock 4.2 to 0,5% (WIFI) to 0,8% (HSDPA) per hour with disabling some stuff that i dont ever need.
Market notifications
Latitude
Google apps like Currents, Play movies, Play books etc...
This is great, but sometimes after usage it still felt like the battery keeps draining as the phone is in use with the screen turned on.
What now happenend is really weird:
I did set a custom reference in BetterBatterySats and left the phone on the table for 1 hour. No unneccessary apps running in the background. But it drained 7% in this hour. As you can see in the screenshots, the device was in Deep Sleep most of the time and there are no noticeable Partial Wakelocks.

But how the heck is it possible that i lost 7% in one hour while deep sleeping? Is there any sort of app that can tell me in this particular case what went wrong?
Any info is highly appreciated.
Best,
ras
k9 mail seems to be one of the culprits
nope. it polls 2 accounts every hour anf therefore uses cpu time of approx. 0,4%. thats even even the case in that "awesome battery life" area seen on the last screengrab. a total of 15 sec. cpu time can't hurt that much.

im pretty sure that this would fix it.
but because this happens from time to time (though this is the first time i can document it because auf BBS) i want to know whats the cause of this. it is pretty annoying to leave a phone on the desk and to find it drained empty a few hours later. this would have happened if didn't pick it up after one hour.
I get a similar problem too. Only way to clear it is a power down and restart.
Well, first of all, can we really be sure that those 7% aren't within the battery measurement margin of error?
Considering of course stuff like temperature, sensor's reading delay and other electrical/chemical/whatever stuff the battery may go through after heavy draining like you show in the graph?
I really don't think that % stats are that accurate, but that might just be me.
Some guy disassembled his Nexus S and measured the energy drain with accurate reading devices. Maybe someone should do the same on the Galaxy Nexus. Because if one software says there's no cause of drainage and another say there was some drain, maybe one should confirm which software should we rely the most.

maybe it happens because the voltage still gets down because of heavy use before. if this is the case the drain should stop at some point and the battery should not die completely.
i will def. keep an eye on this.
Its the fundamental problem with android and our battery technology.
One of two things need to happen, Google needs to get their act together (think project butter but with battery) or the OEM's need to start providing better battery technology. Its ridiculous that over the past 3 years there have been NO significant battery technology improvements. Yes, processors are becoming more efficient and using less power, but that is only going to take us so far. **** needs to happen and Google needs to press it.

try flashing different kernels and see which one suits u the best.every phone is different.u may also wanna underclock and undervolt. also change the rom may b if changing kernel doesnot work.ine suggestion.XenonHD rom with its stock kernel.
The stock battery is a joke at 1800 and the extended is 2100...I had both and both sucked although the 2100 was a lil better. I have the 3800 Seiko battery now and that will last me all day. Makes the phone thicker but its better then charging all day and worrying about what's killing your battery.

Turn off features when not being used like data NFC GPS.
Also avoid auto task killers
How much does it drain in one hour? Battery drain depends on many factors. The mains ones would be what kernel and ROM you are running as well as what "features" you have turned on. For example I am running CM10.1 with the stock CM kernel and I usually get around 16-18 hours of battery life with 1.5-2 hours of screen time.. that is with all of the features (gps, NFC, etc.) turned OFF.

How on earth can you drain a 3800mAh battery in one day? Nonstop internet radio AND 3d gaming on full display brightness?
I am currently using PA rom with franco kernel. Normal day = roughly 13-15 hours ish.
By normal day I mean around 30 minutes of talk time, about 1 hour ish web browsing and like what, 30 minutes ish of youtube? Of course, sometimes I am free and end up playing games on it for couple hours lol, but the stock battery seems to be plenty enough to me.
My battery makes it about 15-17 hours,with about 1 hour gaming,1 hour browsing and talk time around 1,5 hours...Xylon + Purity Kernel!
It is what it is. This is Wi-Fi only on this charge:

Keep screen brightness down low.
If rooted use setcpu and choose a screen off profile of 350mhz maximum - I find this a real benefit.
