long time android user, and my GF just upgraded to her first smartphone to the galaxy nexus, same phone i have. and the battery sucked, she had 50% left and went to work and within 2 hours it was dead, so i unlocked/rooted. and installed aokp 3 milestone along with franco krenel to the latest milestone. same rom and kernel i have, and i get atleast 14+ hours on regular use nothing turned off.
her battery status looks like it usally the cell standby to blame, could this be a hardware issue? i completly wiped data/dalvik/battery and did new install, going to try again flashing back to complete stock. but could this be a hardware issue?

Turn off 4g.
have you checked if you both have the same radio? you can try that
also maybe check hows reception on her workplace
So... she had bad signal. Phone sat there trying to get 4G / hang on to a bad signal. Will drain the battery 100% to 0% in a few hours if you let it do that.
no i haven't tried turning 4g off yet, shouldn't have to i wouldn't think. she lives in seattle and i live 30miles further north of from her, and i don't have a problem with 4g conection. but i'll try that just to see if it gives a different result.
Well I can tell you right now, AOKP gets absolutely HORRID battery life. Try BAMF.

Download juice defender and set it to balanced. You will see a HUGE difference with standby drain.
If you have a third of the time without signal, I would expect energy to drain a lot, as the radio will keep trying to find a signal and consume way more energy than if it is connected and in stand by.

Nothing wrong with AOKP battery
yea im useing AOKP and get great battery on my phone, but not hers, thats why i was wondering if it COULD be a hardware issue, or if this is always a software issue.
Update to 4.04 u will get battery like this.

Ditto that. It's easy to blame a particular ROM for one's battery woes, but the truth of the matter is it's invariably something else causing the drain.

Her signal is destroying the battery, turn off 4g and if she only does the Facebook thing and messaging do the following

Constantly turning on/off mobile data when the screen is off will more than likely drain the battery more than leaving it on. Not to mention that you'll get no background sync or notifications.

No I think you have to turn it off if its right on that fringe area. Plus lte networks and radios are very immature ans have a lot of years to get fully optimized and tweaked to match current cell coverage performance. You're using a brand new network technology that has a long way to go. Beta testing.

Guys, the GNex I am using is VZW LTE device.
I know its battery issue and have been playing around to find the best balance to use both LTE/all awesome features while keeping the phone alive for sometime.
So far my set up ,before I went bed yesterday, was pretty satisfactory: Franco kernel 15.1 + Gummy 0.7 + Hybrid Radio .
Before I go sleep, it has 31%.
This morning, after 5.5 hours sleeping, I press the phone. It is DEAD, seems long time ago.
Took a screenshot of the battery usage, here it is

Any idea why this may be the case?
I tried to look at the wakelock info but because the phone was dead, I can't really see what was there using "since unplug".
May run it down today and monitor why =((
Well, the last drop was when you seemed to have a really bad signal for some reason and the first drop was when you were actively using the device, so you should look at the apps you were using and what you were doing at the time. Outside of these two drops the device had a normal signal and normal battery drop.

Thanks . I do acknowledge the active use part and not surprised. What bugs me is that it was on wifi at last 30%.... so with wifi on,no usage,a change in radio signal can cause this drainage ? I think this is not normal

Same has happened to me, and a few others. There are posts about it on Androidcentral. Basically the phone drops the network then spends the rest of its battery trying to reconnect to it. Its possibly an authentication issue. It has happened twice to me. It doesnt happen if you leave the phone in 3G mode. Even with WiFi on, it can happen, because the phone still needs to maintain network connection for phones and data. This is on the LTE Nexus,

With low/no signal, the phone boosts power to the radio and tries to search for the signal. This is normal cellular phone operation and has been for many years.
It's a pretty big drop, but as has been said you can really hammer your battery when your device is searching for signal.
I notice that your screenshot shows wifi on.
Franco 15.1 had a faulty wifi driver that was sapping people's batteries. This is fixed in 15.2. Flash your Franco to 15.2 and those problems should go away immediately. My idle drain is now 2mA.
Have you tried Juice Defender? Give it a shot. It is a big help with standby drain.

4.0.5 can't come soon enough. Hopefully it will actually fix the dying radio issues.
You have 4g on.. that's why
Sent from my Samsung GNexus <3
WOW! what a drop!
What ROM, kernel and baseband are you using?
4G can't be the only reason for such big a drop!
Looks like the phone lost signal and never found it again... draining the battery by looking for the signal.
Sent from my Galaxy Nexus using Tapatalk
On 4g and no signal for two hours; it is actually amazing that there was still battery left.
Try a different radio?
Or, up the minimum frequency of the cpu to 700Mhz (in case you have an extreme variant of the 4.0.4 bug).
Hardly surprising. Something is keeping your phone awake, probable the radio trying to connect to a network for over 2 h. A phone trying to connect without success for 2 h gets pretty warm, even more so on 4G and drains your battery quickly.
Look at your signal its horrible! And 2 hours screen on time.. Your par for the course.

AOKP build 29, Franco Kernel milestone 2, and one of the hybrid radios(I believe 4.0.2 and 4.0.3).
The drop is definitely from the phone losing signal and searching for it that whole time, as evidenced by the network signal being red and the phone being awake.

Here, in my house, my signal averages -80 dbm. The screen wasn't on for more than a few minutes. The radio simply lost signal and kept the phone awake trying to find one.

I DO have the CPU minimum at 700 mhz
I'll go to build 30 with a different kernel and baseband and see if this keeps up.

My radio dropping issues were even worse on the 4.0.4 radios. But it can't hurt to try again.

I've had this happen before when the network was set to CDMA only. It was only once though... My phone is completely stock and I can't wait for the update to hopefully resolve these problems. Otherwise I will have to start requesting replacements until I get a good one.

Yeah. Since 4.0.5 is rumored to fix it, I'm holding out. I've had all sorts of issues with replacements, and my current phone is perfect except for the radios, which is hopefully just a software issue. Anyways, it's better now that I've wiped and everything, but it still drops. So I'm gonna try different basebands again.

What about "his right"? Or do you mean "you're"?
Anyway, try the GladOS kernel. Honestly, Franco's Kernel was amazing a couple of months ago, nowadays.. not so much. I had a big increase in both performance and battery life with GladOS.
hi !
I also have this kind of battery drain... but I don't have 4G, my GN is GSM...
And the battery is draining with airplane mode on.. I'v made a lot of searches and still can't find the source of my problem
Does it take awhile for this battery to settle in? It's just been 2.5 hours since my first charge and I'm already down to 90%. All I did was send a few texts and receive a couple of short calls. Can't remember if I experienced this on other phones but after hearing about how great the S3's battery life is, I'm a little disappointed.
I think it's great. It's a lot better than my Epic 4g Touch, that's for sure.
And 10% per 2.5 hours is pretty good IMO.. That's 2.5 * 10 = 25 hours of battery. That's pretty sick lol.
Just remember to turn off wifi/bluetooth when not in use, and turn off LTE if it's not active in your area (so the phone doesn't keep searching for the 4G signal).
Yeah, wait for it to settle. This phone definitely has the best battery out of everything I've owned...and I've had a few phones, believe me lol

I've been on wifi the whole time.
I sometimes get more than 2 days on a charge. I try not to use phone while charging, causes inefficient charging(supposedly).
this message brought to you by my GalaxyS3 running Phantom's Blazer v1.6
I must be doing something very wrong. I really got horrible battery life in my phone and I only got 4 apps installed: xda, rage of bahamut, Facebook, and power amp. The ones that can be on sync I turn it off. I'm currently running on CM10 but was on stock for about 3 weeks and blazer for about 2 weeks. All with similar battery life. 2 hrs of screen on time with 13 hrs on battery. On my epic touch I could do 5 hrs of screen on with 24hr battery and evo lte 7 hrs of screen on and 18+ on battery. I've already switched batteries so I know its not a defective one. I got no email syncing and brightness is always set on lowest unless I'm outside its at 50%. I will try to post a picture of better battery stats, CPU spy, and see if anyone can help me figure out what I can do to improve it. Really disliking battery life right now and hope it will get better
Sent from my SPH-L710 using xda premium
I personally just went 26 hours with 3 hours screen on time in CM10. That's way better than my Evo 4G could do, so I'm extremely happy with my battery life by comparison. This phone has been awesome for me.
Edit: That time includes leaving Wifi and mobile data enabled at all times, with data mode set to CDMA/LTE. I also left everything syncing like normal.
Coming from a EVO LTE so far my battery life been unimpressive. Loving the phone, but not digging the battery.

I recently switched from AT&T to Sprint and have the Galaxy Nexus on both services.
My signal for Sprint is better than AT&T at my house and I just ran my first battery test to find that with 2 hours of screen time I got roughly 4 hours of battery life on the Sprint phone verses the AT&T phone which I could easily get at least a day out of it...
Is there really that huge of a difference between the AT&T version versus the Sprint version in regards to battery life?
If this is the case, and the battery life on the Sprint version is this bad, I don't know what to do because there's no way I can only go 4 hours without having to plug it in.
Any and all help is greatly appreciated!

Yep pretty big difference.
LTE on the GN is a separate radio, so you have two radios running at once. Battery killer bigtime.

True but you can disable the LTE radio in advances network settings. That being said, there's still a huge difference. I can only get 3 hours screen on and thats only if I unplug at 100% and use my phone nonstop til it dies. Realistically I get 2 hours screen on a day.
I have the Verizon gnex and I get about 1.25 hours of screen time and at least 10-13 hours of life. Of course I can't live without having certain accounts syncing so I just had to suck it up and live with it. I tried many roms and different methods of trying to get more screen time and lasting the whole day... just not going to happen. Seeing that sprint is also CDMA, the likelihood of getting a impressive battery life is slim.
If you haven't yet, try rooting and putting a custom ROM. I'm running cm10 and I really like it.

Yeah, the battery life for our phones is not the greatest, I've found a spare battery to be a must for longer days. I do get better battery life than what you're seeing though, an average of about 4 hours screen on per charge, with about 15-17 hours of standby using the standard 1750 mAh battery.

Yup, the GSM guys get much better battery life.
My VZN Gnex has less than 2 hours screen time with mixed LTE and wifi on a good signal. That said, I'm still going to complain no matter how many people say to switch to 3G. I believe consumers buy products because they should be good, not so they can make sacrifices after purchasing a product. As of yet, the VZN crowd doesn't have much of a choice for Nexus devices, so Gnex it is.
Make do with what ya got and don't let some battery life stop you from enjoying your phone. Just charge your phone if you get the opportunity and don't let it bother you.
Other phones are worse, some r better. No one says u can switch to a phone with better stats. I'm not complaining cuz I come from a droid charge where ubhad to tweak the crap out of it to get 2hrs of screen on time.
