I don't know what is causing this issue in my Samsung Galaxy Nexus, it's a kernel problem? Any ideas? Suggestions? How to extend a bit more my battery since it drains in 2 or 3 hours as maximum (see the attached images for more info)
Is your device supposed to be idle during this period of time? If so, then perhaps you have the USB port issue, which one of it's symptoms could be phantom charging. Phantom charging basically means that the device thinks it is charging which turns the screen on and also keeps the device awake.

Maybe but I'm not so sure since phone screen is off, maybe another things, any application or CM issue?

same issue
I have the same issue. I was on the stable release and the battery drain was terrible. I went from all day battery life to about 6 hours or so. I updated to the nightly builds hoping it would fix it. Still terrible battery life. I have pretty idle usage too. Any ideas?
I was having issues with the battery life on nightlies until the snapshot hit at the end of last month. Then it drastically jumped to better battery life for me. It's been much better since then on the nightlies.
I do have a battery-chugging app (pedometer), but even with that, the battery life went dramatically up after the snapshot.
magical fix
Gave it a full charge and updated and the issue is gone. got great battery life the other day.

I'm sure others have this issue: battery battery battery.
I'm on CM9 nightly (3-02-2012) with francos M1 kernel. Have not changed anything of the settings. have a pretty lean app collection. The problem is not the phone not going to deep sleep. The phone uses very little battery when screen off. My problem with this phone is when you have the screen on!!! As soon as I start using the phone for anything, the battery starts draining fast.
For example I unplugged the phone at 7 Am at 100% this morning and by 7:15 I had 91%. Turn the screen off and at 9:15 I have 89%. Is this some kind of battery programming thing or does this phone just eats battery when in use. I have the OEM extended battery.
CM7 did the same thing to my Nexus One. I lack the knowledge to know what in the stack was causing the problem. I'd guess something was tuned more for responsiveness than battery efficiency.
Or the fact that it's BETA.

what are you using now?
I switched to jellybean (android 4.1) recently. The system is great. However it drains the battery much more than cm7. During a night the battery can reduce from 80 to 60. Is it normal? If not is there solution to extend battery usage?
Unfortunately, that is normal. Turning the fire off can save the battery, but I just charge it everyday. Compared to rooted stock, battery usage increases between 10 and 20 percent for me under normal use.

According to Better battery stats, most of the drain on my Kindle is caused by AudioOut2 wakelock. I failed to resolve the issue and i'm not sure what is causing it. I would like to know if anyone else experienced similar issues.
IMHO, it must be sort of a bug since JB is fairly new and devs need time to resolve all the issues.

Same exact issues here. And I agree that it will (hopefully) get ironed out over time.

I don't seem to seem that terrible of battery life with mine. I'm running twa_priv's cm10 and during the night it might go down about 7-10 percent. I do have Wi-Fi off while in sleep which helps.

That's not normal for a standby... it should be <5% ...not the mention that device does not have to communicate with 2G/3G networks (unlike smartphones), and on my smartphone i get average of about 3days (medium usage, light on wifi) without recharging
It's a bug - some process prevents device to go to sleep (aka. wakelock) which causes drain. I expected at least 2-3 days on a single battery charge, and tbh, recharging it daily is little bit disappointing Something tells me it's a kernel bug since i encountered it on every CM10 rom so far :S

Well coming from an previous ICS build it's a major improvement. Typically the battery life from ICS builds(That I used, Energyrom, AOKP Kindle Edition, GedeRom) would drain 20-30% nightly like the OP said, so coming from there it seems like JB fixed whatever was killing the battery. I can probably go a week with light usage on my kindle before I recharge it. ICS in general drains the battery on any device. I used to get 5 days on my Droid 1 running CM7. With ICS I'll go through 3, though I never want to go back to Gingerbread, hahahaha.

My record for battery on a smartphone is 6 days... using ICS
Anything that drains battery more than 1% in 1.5/2 hours in standby is bad, no matter what OS version...
I also have the impression that on a fully working Jellybean ROM, battery usage is more intense than on a stock ROM. I still prefer the advantages of the new ROM, and also charge daily. Being mobile, I use the XTPower MP-10000 Powerbank, which gives more than enough battery life and charges the kindle while in use to 100% full. This has resolved the issue of battery drainage for me.
After updating to the latest nightly I have discovered a serious drop in my phones battery performance. Not only does it seem to drain much, much faster but even while charging it still drains the battery. Turning wifi off, screen bright brightness down or even setting my phone to 2G nothing seems to stop it draining. Anyone else getting anything similar?

I've got the latest nightly, my first CM10 ROM. I've noticed a quicker battery drain. ie. about 50% in 4-5 hours, with mild use, ie. phone call, some play store downloads and browsing, and full brightness on the screen. It's certainly not as good as ARHD but its not that bad. I'm putting my faith in the wonderfull devs of CM to resolve this soon. Its not a massive issue for me, and hope it gets sorted in the near future.
I'm using the kernel which comes with the ROM which I'm assuming is stock.
Does yours drain even while charging? It's not that irritating no, just an inconvenience really.

no drain while charging. I'm sure battery life will improve as the ROM does.

I was using stock Sense for a short period of time but it seems to me that cm10 takes more battery. And I am using JuiceDefender.
I think that is because I am on Vodafone and having troubles with the network in my home area.
I want to upgrade cm10 and my radio.

hey guys
I'm new to GNex (3 days user here )
my nexus has a serious battery drops when it reaches to 40% on every roms and kernel!!!
it is like this that when battery percentage is under 40% it drains super extremely fast even w/o any usage to nearly zero ( in about 20 min ) of course some times it even does not get to 20% and phone shutdown!!!!!
i also calibrate battery but no success .
( my battery usage above 40% is normal and i get nearly 3+ hours screen on with moderate usage but it sucks below 40%)
any help/suggestion/etc is welcome.
thanks in advance
edit: screen shot added
**********************************************************************
i notice several nearly same topic but no one exactly mentioned to my issue so i created a separate thread
sorry for spamming
Do you have consistent network signal throughout the day? Just saying as 40% may have been reached by the time you get back home, for example.
Have you checked if your phone wakes up too often - triggered by some application?
(Further to above example, perhaps some location based applications starting up?)
A screenshot of battery usage would be nice.

no in every time, every where it is the same
i also monitor battery with better battery and there is no such culprit
as soon as my battery get to 40% period i'll take screen shots
thanks bro

any help? solution?
When you say you "calibrate" your battery, what exactly do you mean? If it's wiping battery stats, that has nothing to do with anything even remotely related to battery charge or indication.
From the screenshot you posted, it looks as though your screen is constantly on. That's another tangent, though.
You'll need to try a factory reset, but be advised you'll lose your data. If that doesn't fix it, then you're likely looking at a bad battery.

It really bears mentioning that there's no user calibration of the battery. Anyways, if this is happening regardless of rom, then you're looking at it being defective hardware. You'd want to first try a new battery. If it still exhibits the same symptoms, the problem would be the phone itself.

You could try and rest the phone (switch wifi off, screen off and keep phone unused), and see if the drop is still drastic after say 50%.
Tried the ZenSeries v8/9 too? I had good battery times with that, close to 4 hours screen time with 25% remaining.
Do check what month the battery was manufactured on, and if it's a recent manufacture month, it may be faulty.
I have the same problem too with my Yakju. I am using stock ROM updated to JB 4.2.1 manually. Battery drops dramatically from 40% when sitting idle.
Dear XDA,
I've tried various 4.2.2 ROMs on my HTC Desire HD and experiencing horrible battery life.
I do not know what to do, from 100% till 0 in 2/3 hours, while just being standby. It's not the battery since I've replaced this one some days ago.
Currently running the cm-10-1-unofficial-ace, a nightly by Mustaavalkosta.I am having a 3G connection with Sync on, turned location related actions off. The Kernel is also by Mustaavalkosta (3079-3.3+)
What could I possibly do to fix is?
Much appreciated!
No1?
from what i read and experienced it isnt a rom issue. that being said, search the numerous battery threads here, a good start would be better battery stats thread

Can you say with certainty that rolling back to an older version of Android would give marginally better battery life?
I had a similar issue to you several months ago. My battery just became useless. Since I switched ROMs frequently, I also thought it was the ROM, but ultimately the battery was at issue. The Desire HD is getting up their in age, and so are the stock batteries that came with them. They can go from a decent charge to holding a pathetic charge in a short amount of time. Suggest you pick up a new one, you can even get higher capacity batteries for 10-15 bucks online.

Hi there, thanks for your help!
I did buy a new battery, one with an increased capacity. It seems that a simple battery calibration tool + juicedefender is doing the job pretty ok, the battery life is somewhat still disappointing as it was before, however acceptable.
You need to flash the Kangbang stable kernal V3.3 I believe and also use greenify to kill maps trying to get location and any other app thats opens without you wanting it to.
I had RC! CM10.1 and got 16 hrs and 30 % left before I cracked my screen. Now waiting for a replacement to fix it.

That's really strange since my battery drains to 90% in 5h standby with stock battery.
Have you tried reflashing the ROM?
