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.

So you don't see any other issues with 15.2?I seen people reporting more drain on battery or overheat . Those are just anecdotal ?

I m using domination HD ROM. But have used kernelpanic as well I found this problem in both the ROMs wifi takes a lot of battery juice and when I am using the phone wifi keeps getting disconnected and connected. Is it a known issue?

I'd day it is normal. It isn't actually sucking up much power. Mine is at 65% and my battery is still almost full.
Is that so ? How many hours after it's plugged off the charger? I fully charge my cell and if I keep wifi on in the night. in the morning it comes to around 80 percent in 7 hours
Sent from my nitro hd using tapatak
7 hours, was still at 90%. Had it on all night by accident. Wifi becomes negligible when I begin to use other apps. Any game outweights my wifi really quickly. Anyway to see exactly how much drain an app has aside from the "about phone" "battery use"?
Now, please, screenshot of 8 hours with wifi off. Then we'll talk
I use systempanel app for it. it doesn't show wifi drawing a lot of battery juice though. But still do you notice wifi keeps getting disconnected?

Quiet impressive. My guess is you have not much installed there, no push mail, no weather, nothing like this?
The signal strength seems to help this as well.
My phone left during night with wifi on, cell signal at 2-3 bars (although I can see the cell tower from my window 3 block away), plugged into computer in sleep mode (which for some reason doesn't charge the phone), in the morning after 6 hours leaves about 80-85%. But I do have 3 push mail boxes, weather, news and gps enabled.
btw have you noticed that the temperature is always generally above 35 degree C. even when the outside temperature is below 15 and the device is untouched for hours.. in the screenshot.. temperature shown is 32 while the outside temperature was about 15. and it was taken in the morning after untouching the device for 7 hrs.
Have you seem something like this in your battery consumption
Sent from my unlocked rooted Nitro HD using tapatalk
Anyone got any idea what is draining my battery sooooo fast? I've had strong signal all day, for the most part minimal brightness..turned wifi of when not in use, didn't even play any games today... I left the house at 8:30 and it was dead at 6:45, before I even got home. Also, only made one short official today.

The built in LG apps are known to eat up the battery. If you are rooted, you can use NoBloat to disable these applications.
Here is a website that has a list of the applications that are safe to disable: http://androidadvices.com/optimize-lg-nitro-hd-phone-performance-removing-bloatware/
I'm not gonna lie, I'm scared to root it. This is my first Android phone.and if I screw it up I won't have a phone for quite some time.
Sent from my LG-P930 using XDA App
I understand your fear, but if you read the directions closely and go slowly the likelihood of bricking the phone is small. Rooting by itself isn't too dangerous - the dangerous part is loading CWM and ROMs, and the risk will be greatly reduced when (if) we get CyanogenMod for our phones...
After CM9 came over to our Phone still Wifi takes a huge percentage of battery drain and usage. I have seen my frens Galaxy nexus and his wifi was on for 10 hrs still it was taking 3% of battery . in our case it would take more than 20% if its on for 10 hrs
I am on CM10 now and WiFi is still the biggest battery drainer by far..
on other phones typically the screen was using the most battery. WiFi is typically battery efficient.
My phone went from 95% - 68% with WiFi on (but not using it) AND while on airplane mode.
There is some issue with wifi drivers
My battery died in a few hrs today and the culprit seems to be 66% cell standby. I've never experienced this kind of drain before. I'm running the latest Franco Kernel and I'm wondering if anyone else is seeing this?
I just posted something exactly like this earlier in the day. Do you have google chrome and recently updated? I think when I just uninstalled it, it fixed my problem...
Sent from my GT-P7510 using xda premium
would be amazing if you actually posted a screenshot of your usage, with awake time, screen on time, and network state....
Leave your screen on all of the time. It will make the cell standby percentage go down .
On a serious note. what's the time without signal? Just press on cell standby and it will tell you the percentage I think. It sounds like you didn't have coverage and your phone was constantly trying to find it...which would kill your battery fairly fast and probably make your phone warm in my experience.

I've noticed that juice defender ultimate hasn't been running so maybe this has been a problem I didn't notice, I turned it off because I hate how long it takes to bring 4G back up...
phone has of course been on the charger since I was less than 10% but:

What did your network level look like over that drain? It looks like you have bad signal, but it shouldn't effect it that much if you're on WiFi the whole time... as noted before, a radio constantly hunting for better 3G/4G signal can really drain the battery.
How much screen on time was that? Probably pretty low?
56% of the time you were without a signal? Where do you live? Alaska? On a serious note though...I'd recommend switching to 2g/3g or wifi when you're having trouble finding a signal.

WOW yeah didn't even see that. There's the drain right there. Your phone is boosting power to the radio to try and get a signal and just obliterating the battery.

At home, my signal is generally 2-3 bars 4G, maybe we're having tower issues in my area. This battery consumption is definitely not the norm for me. Kind of took me by surprise which is why I posted...

So it is true that when your phone did not have network connection, it will constantly find coverage and thus account for the awake time in the battery state? Therefore eating up the battery life, even though the screen is off?

Yes. This is true. The phone pushes more power to the radio also, which drains the battery.

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.
Sent from my Galaxy Nexus using XDA
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.

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.
Hello all!
I'm a brand new and happy user of the galaxy Nexus. Bought it two days ago and of course I started to play around with it quite a lot.
It was not new but it was used rarely, especially in the past 3 months. The phone itself is five months old.
I am just wondering if it is normal that the battery drains so quickly. Considering the fact that as a new toy i am using it quite strongly I still find it too fast eating the power.
The other thing is that could be in relation with this is that I think it is very strange seeing that something keep waking up my phone when it should be sleeping.
Let me attach a screenshot about battery stats. Please ignore and forgive it that it is in hungarian. The important thing is still visible.
What shall I do?
Thanks in advance!

How much screen-on time? With crappy signal and a LOT of awake time, I'm not surprised at all by 15hrs of total time.
You have an app (or a few) keeping your phone awake quite often. That alone will drain the battery. Try something like "Better Battery Stats" to see whats keeping the phone awake.
Yeah I forgot to mention that I had very bad reception for that time in the mountains. Screen on time was around 45 minutes - one hour.
How shall I look for apps not letting my phone going to sleep? Any free subsidiary for Betterbattery?

If your getting bad signal I suggest turning off your sync unless you need it, most of the time battery life is a result of the user or the apps they use better battery stats is a good app to find out what apps are keeping your phone from sleeping, also just a tip posting about battery life can get nasty responses good luck man

Judging by the wake bar, go to Latitude and in Location Settings sign out of Latitude. Google Now still works and you won't get your device constantly updating your position while screen off. I believe when you turn on Google Now it automatically signs you into Latitude as well.
Just trying to find out how to spy out apps using my phone than they should.

get BetterBatteryStats. I am sure that you'll just see googlelocationupdateetcetcwhateveritwascalled at the top of wake locks
Ok now I am quite sure that it's the wifi that keeps waking up the device. After testing two days with wifi on and yesterday with wifi turned off it seems obvious.
I also find another topic where an other guy found the same answer... Very strange and very annoying.
With wifi:
Without wifi :
Both test were running during night when the device should sleep as well

I think the betterbatterystats is the best way to go as mentioned earlier. You might find that it's an app that is calling the wifi connection that causes wifi to appear neat the top of your stats at present.
I have an unrooted M919 which is running 4.4.2 (FNB4). Problem I have is when LTE is on, and I have about 2 bars signal in my room, the battery drains quicker than when the phone is only on H+ /WCDMA.
My question, will the 4.4.4 firmware improve my battery comsumption?
Thanks
In general LTE is known to consume a lot of battery I recommend u stick to H+/WCDMA it what I do .
I doubt the new firmware will have any battery improvement
LTE alone is a battery drainer
LTE is not that bad a drainer, its low reception that will consume a lot of power. The update may not help much, but doesn't hurt to try
I have already packed my M919. I will return it... it makes no sense keeping it it I still have to disable LTE... I will just keep my stellar i9505
The reason I bought the M919 is to have LTE, but I never expected it to suck my battery that fast. I went out with the family to do some shopping this afternoon, from 4pm with 75% battery ( I have rebooted the phone, and greenified everything I can), then after dinner at 8pm, I had 35% left on the battery.
Unless you were actively using it the whole time there is no way it should drain that fast. Did you check battery stats? I wouldn't give up that fast but it's up to you

That kind of drain is not caused by LTE.
+1. Even in marginal signal areas where it is spending lots of energy hunting for signal, it should not drain that fast.
Definitely investigate what is causing power drain. At that rate, it's not LTE or "hunting for LTE" that is causing it.
LOL.. I hate you guys... I will have to unpack the phone and start again then....
But seriously, I have used all Samsung phones... look at my signature LOL... I have never had this kind of battery drain... but I will give it another try, but I am not optimistic because I have reflashed the firmware twice, and have reset the device about 4x already with the same issue...

Edit:
I also always disbale things like google+, and other samsung bloatwarez... so nothing really sinisterly running in the background

Yes I use that, and I don't see anything running wild... I am flashing NH7 now....
What about the stock battery stats? And also do you have Google now disabled?
These are what I habitually disable:
(I am surprized, "SNS" which is related to facebook and twitter is not on the NH7)
I don't have facebook, twitter and other social media apps installed....
The 4G signal you see in my screenshots is because I only used WCDMA connection at that time.

Just an update, I went out this morning for about 2 hrs. Only time I used the phone was when I received a call which lasted about a minute, used the calculator once for less than 30 seconds, and the only times the screen was on was whenever I checked is if I have LTE signal...
I notice, the "Wifi" is "On" but I am sure I have turned it off. "Wifi calling" is also disabled in case you ask...
Go into WiFi, settings, advanced, and disable always scanning. I forgot about this one, it is a battery drainer for sure. You should get much better battery now

One other thought: perhaps the battery itself is not up to spec, and so "30%" of your battery isn't the same number of milliAmperes-hours it should be.
