I was under the impression that the battery drain issue was fixed with new sc 2.9.2. Anyone else still having issues?

Im only having problems with voodoo kernels. Flashed ec10v last night and had same issue. disabled voodoo and flashed back to eb01. did full wipe this morn and installed sc 2.9.2v and im back to same battery issue. its irritating.
No issue for me
I am actually seeing much better battery drain... I am on SC2.9.2V
im unplugged almost 4.5 hrs and im at 95% still....
sigh... working on battery calibration now. i have to leave for work soon so w/e i do it has to be now. lol. no comp access at work so i cant odin cwm if i break it. might just flash back to sc 2.9.2nv till i have time to play.

I feel your pain. In my case, and maybe yours, I think the culprit is the horrible coverage verizon gives me.

Does your battery drop to 0 that fast?
I have had a time where by battery dropped 15% within 1-2 hours, but then I was stuck on a certain percentage for hours.
Hello, I started a thread 2 weeks ago and it has some good info there. Take a look.
I update the OP regularly adding post made by others. No one has posted anything in a week. If you find how to fix your problems please post it there and I will add it to the OP. Its up to everyone to keep that thread alive.

I've had issues as well. Mine are related to GPS wakelock. Every fresh boot I will consistently get a partial wakelock of 100% because of the GPS. Simply opening Maps and closing it will force the wakelock to release.
I'm curious as to why others aren't having this issue, yet some of us are?
I've tried the EB01 modem as well as the DL09 modem and its the same results. Aside from this, battery life is great...

When you say 'idle' do you mean like zero apps running (like stopping everything running via a task killer). Then what,, like keep the phone's screen lit up by not letting it sleep and monitor the battery drain over a period of time? I'll have to try that and see how mine does. I'm guessing mine will prolly drop 15-20% as well if I have the screen lit for a solid hour.. hmm
I didnt really think mine was working 'bad' though, I just figured thats about what these batteries in these could do. I can make it though a day without a re-charge but I admit I have to budget my usage of the phone thoughout the day.. not using it for long solid periods of time and such.. If 15-20% an hour drain would be considered 'bad', how much should it drop in an hour to be considered working 'well' in your opinions?
Well I spent all day charging, using and then recharging my phone. it died in about 5:45 hrs of med to heavy use. I used the method outlined in this thread. http://forum.xda-developers.com/showthread.php?t=987529
I lost 5% battery in 45 min this morning which would have been nice but it was idle in my pocket. :-(
I gave up... reflashed 2.92nv and im checking to make sure its not having same issue.
If anyone has more suggestions there are now 2 pages i found for this problem specific to the facinate.
My battery is pretty decent after clearing battstats. Heavy use I'll lose about 13% per hour. Idle is decent, 3-5% per hour.
2.9.2 ec10voodoo
Ok I did a little test with mine - I set my LCD screen timeout setting to 10 minutes, turned my wifi and gps off (left the cell radio on), killed all apps that were running in task manager. Then I sat the phone down on my desk with the screen lit up and tapped the screen every 8-9 minutes or so just to keep it from going to sleep for one solid hour. I didnt do anything else with or use the phone in any way during this time. My battery dropped 18% in one hour. Think I'll try the batt stat clear procedure and redo the same test and see if its any different.
Mine is horrible. For some reason, it drains in proportion to my use. If I use it constantly, and hardly put it down, I'm lucky to only get 6 hours out of it.
I don't get decent life unless I put it in airplane mode, turn off rotation, and don't use it. Then I'm good for
16 - 18 hours.
WTF¿

I can understand getting 6 to 8 hours if your a heavy user. but Im only concerned with my idle battery use. Juicedefender help some what. you can get it on the marketplace.
I'm still having the same issue with the nonvoodoo version. I'm still not sure how some users are getting over 40 hours of battery life.
as far as I can tell recalibrating my battery had no effect on the battery life. I plan on trying to recalibrate 1 more time in case I messed up the process. I will post my results in a day or 2. good luck to the rest of you. if you find anything out that may help me or anyone else please post it here

It sound like you have a faulty battery if it only lasts three hours, I think you would have to be gaming to flatten a good battery in that time.
John.
Mine is the same. If I'm browsing the web, using instagram, Facebook and receiving email my battery will go from full to empt in easily 3 to 4 hours.
Backup, factory reset, reinstall apps from market (try to install only the ones you use a lot at first), restore the data you need. If you're still seeing the same things happening, install a battery logger / system logger. Use this guide to see if there's a rogue app that's causing the trouble: http://forum.xda-developers.com/showthread.php?t=937080
If it's still acting up and you cannot identify any unusual drain, I'd ask for a replacement.
After you get things sorted, you can use apps like Juice Defender from the Market to prolong your battery life even more.
-KJ
thanks guys for the sincere contribution.... i hope your advices help me...
my top battery consuming activities are:
temple run
google play
msging
go launcher
and nothing else
gaming and browsing certainly make the battery drain almost visibly..
things above and beyond the above to try include..
1. reduce screen brightness
2. reduce frequency of or disable background updates by apps
3. no vibrate notifications
4. work more, play less!..lol
the battery life of the Note is great, unless you use it .. a battery monitor will allow you to see the battery drain over time..this will help when you address item #2 above.. if you accept default refresh times, and have lots of social apps your battery can die in 6-7 hrs without even using the Note at all!..
I really love when people give the tip to not use your phone as a battery saving tip

some hints for better battery life
Got mine the other day. First charge battery was fine. Second charge went down 7% in about 5-10 mins. Then it restarted :/ Came back on, down to 88%. Turned the phone off as was frustrating me as it restarted 3 times yesterday. But when I turned it back on I was at 83%?
Hasn't last me the day, it's on charge now. When it pops up telling me to charge it tells me to shut all apps and that using while charging may effect it charging. Is this correct? I didn't think it would have anything to do with it?
3 to the 4 hours continuous use is normal... Only if your phone is standby and then depletes in that time You should be worried. I recommend researching wakelocks in that case.
There are many variables that can atribute to batterylife depletion. Eliminate those first and you will have your answer.
I had best results on stunner version 19. To bad it has the death kernel (leaked ics)

Usually that wakelock is there cause you are charging, or have USB plugged in

Had the note for 2 days. It came with LA4 FW and updated via Samsung Apps for the latest FW.
Battery drain, that was none on LA4 became very strong!
Installed Better Battery Stats and discovered that the CPU was always running.
Factory reset solved it...

Is your screen at max brightness? When you click on your screen in that screen what kind of on time are you getting before it's dead? I get 3-4 hours usually
Its all the way down and on auto. And it says 1 hour and 45 mins

What does betterbatterystats say?
I have the same problem, but I get around 2:30 screen on. About 6-8 hours usage, I've been trying different ways of charging to see if it will extend life, I might try to use power saver mode next if I can't find a way to get better life.
I have same problem too. This is day 7 for me since I acquired the device. The first day I thought the drain was from the amount of usage during my setting up the device. But now even after a full charge. It will be down to 92% just sitting in my holster in about an hours time. The battery would drain in about 8 to 10 hours.
The only massive usage in the battery status page I see is the screen and I have set that at lowest brightness and then auto. Im using battery saver as well. Im thinking about taking this to AT&T store tomorrow to see about battery or device replacement.
We shall see.

That is definitely abnormally high battery drain. I get less than 1.5% drain / hour when the phone is idle. So your drain seems to be more than 5 times higher!
It may be a misbehaving app.
BetterBatteryStats, is good because it gives you detailed info on what is consuming your battery.
This is what mine looks like

If you are in a building with pretty thick walls that could drain your battery also due to the phone using more power to acquire a signal. I work in a building that house a lot of servers and notice it uses more battery than when I'm not at work.

This i can agree with, when i visit my parents in the middle of nowhere my battery on any phone every has always died in 3 hours looking for a signal so this might be relevant if you're in a porr signal area.

I'm having this problem too, I don't understand BBS but here's a screenshot of the screen.
I'm tired of this, how can a new and expensive cellphone's battery lasts like 8 hours without even really using it.
My drain was resolved. Android battery stats indicated the screen was draining the battery. BBS indicated my WIFI use was. But neither usage seemed too much.
A visit to the local AT&T store got me a new battery. Albeit some arm twisting occured trying to convince them of the hardware issue.
Yesterday, after overnight charge the previous night, I ended the day with a 72 % battery.
Did a quick charge to 100 percent this morning and my charge dropped 1% in 1 hour. With heavy usage, I sit currently at 72%.
Much better results and happier.

Hey guys, i noticed my phone has been dying faster than usual.
Last night, i charged my phone to 100% and then unplugged it and went to sleep. I used it sparingly to answer a couple text messages.
But I've been noticing this everyday: the "phone idle" is eating a crap load of battery! I wish better battery stats was easier to understand so i could see what the problem is.
Does anybody have ideas as to why my phone is eating so much battery just sitting around?

one quick thing i can recommend is to turn off features you dont use while you sleep. like gps,wifi,data. that alone should help some, as simple as it may be.

Interpreting the battery stat, it's easier to guage the battery life based on display on time. Most of the time, my M dies around 3.5 screen time hours.
Hi all.
Just a quick question. My battery life is great but i feel like it could be much better. Here are my current stats as i write this.
With this its saying i will get under 4 hours screen on time, i wouldnt say i was a heavy user. I use my phone quite a bit but i wouldnt say it was alot.My biggest problem is with the android system anyone else have it as such a big drain? Somedays its sat up at 40%
Anyone know what i can do to rectify this? Im currently not rooted..
Thanks in advance
Liam
There are just two possibilities.
LG stock rom is so bloated that it sucks most of battery or GRAM feature is so good that screen time is not really problem anymore.
Forgot to mention, my screen time was 2hr 30 so probably looking at not even getting 4 hours screen on time.. Gonna have to guess that it's the stock rom sucking up loads of battery? Would that cause the android system percentage to be so high?
I'm having the same issue here.. Getting 4 hours screen ttime though...

install greenify. it save my battery. last longer.
I can easily reach 6 hours screen on time. And I'm a heavy user and by no means try to save battery. multiple social networks, emails syncing etc often streaming music and watch videos and brightness set to a constant 75%. This is on StockModRom. So yeah I'd say something is draining your battery unnecessarily there.

Strangely, for me, when I go over ~2h screen time the Android System drain is taken over by the Screen drain. This being said, I never got over 3h30m of screen time - this is with about 10h WiFi (including overnight => ~2% drain) and about 7h 3G. I have noticed plenty of crap among the kernel wakelocks, but I lack the knowledge to remove them in the source code and rebuild the kernel.
Also, BBS is among the apps that trigger a Qualcomm bug regarding sensor kernel wakelocks (sns_async_ev_wakelock), which, obviously, lead to more battery drain.
All of this is not really acceptable coming from a company like Qualcomm (the sensor bug, in particular, is present ever since the S3 QC version...).
I'll second that Greenify is pretty good at saving battery.
I too have had a screen on time of 6 hours 11 mins over a duration of being off charge for over 14 hours
I'm using StockMOD kernel but the ROM itself is stock as i can't seem to get StockMOD rom to boot.
Also if you Root try TricksterMOD and use multicore savings etc maybe get a bit more life from your battery
Hope battery life gets better for you as it is an awesome phone would be nice for you to enjoy it as much as the rest of us

been on for 26 hours now with 2hr 20mins screen on time and still at 62% absolutely amazing!
still unsure whether to root and try and squeeze even more battery out of it!
Still annoyed i never found out what was causing the issue..
Wow just wow. This was my last charge, absolutley incredible.
This includes 1hr 45min of music streaming.
Streaming a 2hr 20 min film.
Twitter/facebook/emails and a tiny maybe 10 mins of web browsing.
I have with cyanogenmod 11 a very nice Akku.
99% Akku - 5 hours standby (Internet GPS.... On)
58% Akku - 4.5 houers tune in radio (everytime Internet on)
I think that's whery good
