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.
My 2.9.2. dropped 5% in 15 minute idle state.

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

I'm noticing that battery life is worse in 4.2.2 - I was on cm10.1 nightlies w. Cm10.1 kernel and was getting about 10 hours screen-on time before I needed to charge, but I'm getting 7 hours at best on 4.2.2 stock (rooted, bootlader locked).
I have the usual culprits turned off - Google now, location services, currents background updates etc. So I hoped I would at least get the same.
Anyone else?

Yes! I just read that. I am just about to do it now.
I can't comment on battery life, but did notice something a little alarming with regard to battery drain. Was on the couch for an hour talking to someone using viber, just plain text. No video or audio. Tablet was plugged into the wall, and after about an hour i noticed that the battery had gone from 100% to 98%. Should not be possible for a simple messaging app to cause the battery to drain faster than it can charge. screen was on auto brightness as well.

Did you look at your battery information to see what was using the most energy? Display is always far and away the highest for me, and if it was on Auto Brightness, depending on the lighting around you, it could have been running at full brightness...which would be a pretty massive drain on battery.

Once the device reaches a full charge it cuts off the power draw to avoid damaging the battery. It's normal for it to hover between 97% and 100% while still plugged in.
I barely get 6 hours of use now.

I did not look at battery usage, but the screen was generally dimmed, where as normally i have it manually set to full brightness, and nothing was running in the background that would not normally be running, that is to say nothing other than android stuff, it's basically a tablet for internet, email and skype/viber while i watch films etc on my computer

Indeed, but this has never happened before and i typically run the device with screen on maximum brightness. on 4.2.1 it would always show 100% when plugged in, i never once saw it drop to 99% or below.
So without further analysis of the issue, it could either be that something is sucking more power, which would seem odd, or that the update has brought about changes to the way the device charges, or changes to the way the device displays the battery level.
Damn guys, I don't know what I'm doing wrong, but I'm jumping around in happiness when I manage to get over 6 hours of screen time lol.
I've been on battery for the past 12+ hours with about 6 hours 15 minutes screen time and still have 36% battery left. Battery seems at least as good as on 4.2.1.

Thanks, I've done this now, and get about 5~6 hours of screen time now with around 50% left.
My battery life has gotten considerably better after updating to 4.2.2. The biggest improvement is how little the battery life drains on standby...it's nearly nonexistent.
Sent from my Nexus 10 using Tapatalk HD
Standby has always been great for me. With stock rooted 4.2.2 I'm getting great battery life. Loses maybe 2% after 8-10 hours idle. In constant use I'm averaging 11 hours on screen. I have everything on and synced but as I'm indoors I stick to 30% brightness. Also, I'm mostly just browsing. With games the life would be less for sure. Totally satisfied with the battery life of this tablet. If yours is getting truly bad battery life I suggest you try searching for rogue apps. After that, try a complete reflash of the stock image which deletes everything. Another thing I've found that helps performance is setting the WiFi band manually. As I have a pretty good router that utilizes both the 5 and 2.4ghz bands I set mine to 5ghz only. I live in a town house and 2.4ghz can be pretty congested even after turning my antenna power up to 150mv or greater. The 5ghz band is pretty open. I'm getting load times on webpages comparable to my i5 2500k sandy at 4.5ghz and ssd with its 5ghz WiFi n wireless card. This is the quickest rendering tablet I've ever used.
As an aside, the complete re image to stock 4.2.2 from Google might fix reboot problems as well. It seems to do wonders for people with battery and other issues on early n4s. My screen on mine is new but the hardware is from launch day.

My battery life is significantly worse after the update. I flashed back to stock 4.2.2. It seems that the problem with mine is my tablet isn't sleeping. Android os is the highest battery user. Maps is taking a lot too. I have Google now and location services turned on so I'll try disabling those again... No rebooting though

do you mean reducing the maximum cpu clock to 1.5 ghz?
My battery life has been pretty good. However, the number one thing consistently using battery is "Android System". Is this normal? Thanks!
Same here. On all my other Android phones Screen is the top user.
U are using ips technology on the screen unlike amold that saamy used which kills the battery in hours in full brightness . As you could see that the iPhone has good batttery life because the 720p ips screen.

I've found that rebooting the phone after taking it off of charge, the battery life is awesome. There seem to be some wakelocks that kill the battery and for some reason, charging has something to do with it.
I don't know if this is why, but I heard the G2 has special screen technology that greatly reduces battery drain.

Those claiming that Android System > Screen for battery use on the G2...I'm coming from a Nexus 4 which is also IPS.

Yeah, somthing about 30% lower battery use or something like that. It's 6 hours since I took mine off the charger, must admit very moderate use, some toying, some photos, some mails and 1 phone call. but still, my phone is at 96% battery. My old S2 would be at 60% at this point.

I tried this and it worked. However, one instance is not proof I guess haha. I will experiment more tomorrow (namely, not rebooting after charging) and let you know what I find. I wonder what specifically about charging may cause wakelocks?
Over 48 hours of use, more than 50% battery left. 3,5 hours screen time. Android system worst offender with 35%, screen 2nd with 25%.

If you look at the programs listed under Android System, try uninstalling the ones that you would never use. This has seemed to help me. But to be honest it was kind of unnessary because the battery life is just crazy badass. In a few weeks or so when the devs have there way this phone is going to be epic.
It is two things, which by the way are great news.
A) LG's screen tech which doesn't refresh pixels when the images are static
and B) IPS
What we can't control is screen power consumption, but guess what? We can control android system consumption through kernels and roms. This means that we can *hopefully* expect EVEN BETTER! battery life since the screen is, for 80% of users, the main culprit for energy drain.
Just a quick note that flashing CleanROM on my ATT LG G2 basically took my battery life from <20% at the end of the workday to just under 80% at the end of the work day with increased use on the CleanROM install. Highly recommended.
Been off the charger since 6:50 this morning. Sitting here at work doing some texting, Words With Friends, and a test call for a co-worker...96% at 12:15pm. My Nexus would have been at 40% by now.
So is Android System different from Android OS?
I normally can squeeze out 15-22 hours since installing Snapdragon Battery Guru. Which has been working great until today.
Here's my situation today:
-100% charge at around 1230am. Light to moderate usage leaves me with
-77% between night before and waking up (only dropped like 2% overnight) at
-830, then i worked from 9 to 1230 so i didnt use my phone too much. But since ive been off work ive been using it more so im not too surprised about my low battery level currently.
But what concerns me is Android OS using half my battery! It says its been active for more than 4 hours and i dont understand where it comes from. Its way more than my screen usage even with a screen time of little over 3 hours.
Anyone know whats up with Android OS? It doesnt tell me what is running when i select it so im lost.
Also ive done many of the suggestions in this thread with positive results. Ive been monitoring my wakelocks and since doing some of the suggestions on here nlpcollector has actually gone down.

Just to benchmark .... I used the phone moderatley ..
I did.. a little over 50 hours of total on time
4.75 hours of on screen time,
2 hours of spotify with bluetooth for the entire time,
2 hours of MapMyRun with GPS running ..
then various text messaging and a couple phone calls
The only modifications i've made to the stop experiance is taking of google's location service for programs, but leaving GPS active .. and changing the screen to auto-brightness, baseline of 50%.
I came from the SGS2 ..... with 1 hour of on screen time and the other spotify and bluetooth .. i'd be around 10-20% after 8-10 hours !!!!!
Mines pretty awesome.

I'm not sure if my battery is defective or not. Right out of the box was around 75% and I drained it until it turned off then charged it to full.
Over the next few days at work it's on wifi and then on 3G/4G before /after work. I pull it from the charger at 7:30am and by 7pm its at 40%. Then on Friday night I unplugged it at 12am with 100% and woke up the next day with 80%. It's dropping like 1% about 10-15minutes. Would a factory reset fix the battery drain? or call for a replacement?

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

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...

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

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

Hey guys i got a s4 for free a few weeks ago and the battery was having issues so i brought a new battery from Samsung for $50. I guess the phone is $50 now huh, still that's a good price. Anyway i have an improvement in standby time over the old battery that seemed to drain no matter what, but i only get around 2hrs to 3hrs screen on time full brightness with a mix of auto. The phone tends to get warm when its below 40% power. Also using the phone drains it at a fast rate, but standby only 1% per 8mins or so witch is good. Im backing up with twrp and titanium backup, ive tried recalibration, and im about to do a factory reset on this (stock touchwiz)

Battery calibration apps are a placebo.
Anyway, let me tell you a little story:
2 weeks ago I watched a 2 hour movie on my phone. Started from 100% ans towards the end of the movie I was left with about 50% battery.
Screen brightness was around 60%, WiFi was enabled and the mobile reception was 4G.
All things considered I would assume I can get 4 hours SOT, since it took 2 hours to get from 100 to 50.
This is on a custom rom and battery oriented kernel settings.
Also take into account that I was watching a movie, so the CPU was idling most of the time. Doing tasks and switching from one app to another drives the CPU up.
Your screen-on time seems acceptable to me. I have to mention that my battery is one and a half years old, but I always took good care of it (I never let it discharge too much and never left it charge too much, as both of those, over time, can reduce its storage capacity).
Im using Albe95 rom with a custom kernal and the battery is draining slightly less, ive reduced my brightness to 60% and its drained from 100% to 77% in standby and extremely light use in 6hrs (about 4hrs standby drained 6% and 2 hrs of on off use every now and then drained about 17%. I guess im used to my old LG L70 D320n witch could hold up at full brightness forever. Will Cyanogenmod 13 bring much improvement for me?

I don't know. Maybe Optimized CM13 because it has a custom kernel and you can select battery or performance profiles.

You won't miraculously get 5-6 hours SOT even if the battery is new.
Maybe with lowest brightness, WiFi and mobile data off you will.
Underclocking and undevolting might help a little, but I don't see anyway of getting more than 5 hours.

Thats not the problem, im bearly reaching a bit over 1 and a half hours SOT

There's a guide in the general section, _Bon_Bon's tweaks.., Something along those lines is the title.
It has a guide on how to increase battery life.
The guide is based on alucard kernel, though.
Alucard kernel is available for any 5.0 and 5.1 roms. But there is no public build for android 6.
Only JDCTeam roms have alucard kernel for android 6. Those roms are Optimized CM13 and AOSP 6.0 rom.

Ok so slowly things have improved but today when it was at 9% (6:30pm charged this morning) it froze up and i pulled the battery. Then it jumped down to 2% at restart! This has happened before (cant remember if it was on stock rom or the note 5 rom im using on it now) from 40% freeze, pull battery, restart, 22%! Any idea why this happens. I talked to samsung about the battery performance and they just wanted me to send the phone too as "its not just the battery" just for more money instead of honering their 3 month ****ty warranty! Stick it samsung my next phone will be lg like the rest, even though i only just brought this damn phone

The freezes might be caused by CPU undervolting, if you did any.
But the battery percentage dropping suddenly is a sign of a bad battery. It might drop 2 or 3% during the boot up, but not 20%.

Samsung say the phone is the problem. Today i got to 40% and it jumped to 30% within 20 mins. Then i pulled the battery and started the phone up, repeating this multiple times to see the battery percentage. It jumped between 24% 15% and 19% up and down each time i pulled battery and restarted (no crashing just to see what happens). Is this enough to tell Samsung ITS NOT MY PHONE.

Apparently they refuse to accept the possibility that they might have sold you a faulty battery, so they blame the phone.
I don't see how the phone might drain the battery from a hardware perspective.
It's possible from a software perspective, but since you changed roms it is unlikely to be software related.
Did you install any apps to check if the phone enters deep sleep? Or if there is anything keeping the CPU at max frequency?

Wake lock doesnt find anything strange. Even twrp battery indicator in my custom recovery experiences the same effects

Ok ive done it a few more times and it seems to possibly be a calibration issue. But ive calibrated it multiple times before

How did you calibrate it?
Battery calibration apps are a placebo. What they do is they delete the batterystats.bin file which, as stated by a Google engineer, has no relation to battery life or the battery display.
Also, that file gets deleted automatically at every reboot by android itself.
What you could do is:
First let your battery fully discharge, until the phone turns off. Then try to turn it back on. If it turns on, proceed to use it until it turns off again. Do this until the phone won't turn on again.
Now the battery is completely empty and you can plug it in to charge. Let it charge to 100% without interruptions.
Take into account that it can take up to 3 hours to fully charge.

Haha done this before to no avail. Will do again but i noticed battery life is generally better if i leave it charging for 10hours after its charged fully. Instead of taking it off when it gets to 100% but i think a long worded and very angry email is about to be sent to the Samsung repair centre

on my travels around google I've read many times that with lithium batteries you NEVER want to completely discharge or overcharge them. give it 10 minutes extra once fully charged, not more. you're damaging the poles or terminals or something I can't remember fully when at either extreme. all you achieve is a shorter lifespan for your battery.
discharge it until it turns off but never until it can't turn on again. it has a chip in the battery that needs to stay powered too.
