Help regarding battery life - Galaxy Note II Q&A, Help & Troubleshooting

Hi all I just got my galaxy note 2 yesterday but the battery life is bugging me.... I feel that it is not normal.. every 5 minutes or less the battery percentage drops by % 1 even if I am not opening any apps and I have GPS, mobile data and other unnecessary things turned off and just using Wi-Fi with power saving turned ON.. I even didn't used it that much yet, no videos or apps that consume a lot of CPU and I always make sure that I kill apps after using them, currently I am just surfing the web with chrome and it is still inconsistent sometimes it drops after 10 minutes and sometimes after 3 minutes, I also turn everything off except for power saving when I go to sleep but after waking up I noticed that it dropped by % 4 .. sorry for the long post guys but I am very worried and I just want to check if this is normal and if it's not I can get the battery or the whole device replaced since I have a 2 year warranty. I also attached some screenshots if you need to judge from them.

Have you updated your Note to 4.1.2?
I recently updated to 4.1.2 and my battery life has suffered.
Hopefully a new update will fix this.
Judging by what others have written, you should get between 6 to 7,5 hours with the screen on. I plugged mine in yesterday efter 1 day and 12 hours. This includes 8 hours om sleep and 6 hours at work -no time to use the phone at work. I did not make note of the screen on time.
As i write the phone has been on battery for 8,5 hours and the screen on for 1,5 hours. The battery is at 54%
Hope this helps.

Thanks for replying
But my device is still on 4.1.1 and haven't touched the software update option and still .. I am not getting that spectacular battery life everybody is reporting which bugs me since I love my note 2.. even while I am typing now the battery percentage has dropped by % 3

It's that a task killer icon in the top left corner? If so, you might first want to try if your batterylife improves after uninstalling that!
Also find the app called better battery stats on play store. I recommend you buy it and install it. EDIT: there is a free version of it on xda too... Then charge your phone to full and use it normally. When the battery starts to get low again, open the battery stats app and look for "partial wakelocks since unplugged"
There you might find the cause of your problems. Post the screenshot of the partial wakelocks screen here if you need help interpreting it!

There is a free XDA-edition of BetterBatteryStats as well.
I got similar battery life as Dmwitz reported, no idea how some people get 3 or 4 days or 7,8 h of screen-on time out of their device.

I have the same problem as you

That icon in your notification bar... Is that a task killer? If so, then that's your likely problem.
When you use task killers, apps that restart themselves or their services will constantly be starting up again, leading to more battery drain. Let android handle your running apps and only manually kill apps that are frozen or highly problematic (uninstall those problematic apps if you can).

Thanks for your suggestions guys I uninstalled the task killer and will try the battery app now, I will let you know once I try it

Battery drain on JB!

Is anyone else having big battery drain since updating to JB? I used to get 2 full days now i can't get 16 hours my phone is staying awake. I'm stock unrooted using juice defender plus. Thanks in advance.
I don't get as much battery I get about 8-14 hrs with 2-4 screen in time I use to get 10-20 hr with 3-4 hr screen on time. I hope they realise a update to help fix the issue seems like quite a few are having.

Yes. I suspect you're probably having the same problem as me. Ever since upgrading to JellyBean, the battery is horrible. Checked BetterBatteryStats, and it's because of msm_otg, it's constantly hitting the device with kernel wakelocks. If I look at CPU states, my phone has been in 384 MHz for 97% of the time, deep sleep 0% of the time. Since it's not sleeping, the battery is draining much faster.
It has something to do with USB on-the-go, but I can't figure it out.
I am having opposite experience. I am getting incredible(to me) battery life. Fully charge yesterday at 430pm and this morning after a bit of texting and calls, battery is at 80%. Pretty good and should be able to get at minimum 1.5 days usage out of it at current rate.
Also, disable Google Now. That's known to be a huge batt drainer.

Sorry for the noob question but how do you disable Google now, never used it so don't know which one it is. Thanks in advance.

This still didn't fix my battery problem. But you'd go to apps -> Google -> Settings -> Google Now. Press the on/off switch at the top right.

Thanks, we'll see how it goes from here.
Did notice my battery was draining more before JB. Once I downloaded JB my battery seemed to drain worse. Finally figured out it was Nova launcher, so switched back to TW and battery is back to normal, with google now on, mainly just get traffic and weather for now.

I apologize for posting in the wrong section. The battery drain continues even after disabling Google Now uninstalling Facebook, pandora and other apps and turning off gps, bluetooth. Andriod OS is staying awake and killing the battery. In data usage delete apps is running in the background at 43 mb? Anyone else?
For me it started with LI3 then into JB.
I noticed Media was at the top of my list when i checked what apps were using battery.
So i ended up disabling the com.sec.android.providers.downloads and so far i think this has helped get my device back to normal battery life..

I don't like any apps that are supposed to save your battery. they usually contribute to battery drain. get better battery stats and see what's causing wakelocks. it's probably location services related to google now. when you don't need it, turn off gps AND location services

Here's a possible problem http://rootzwiki.com/topic/21871-ro...y-build-discussion/page__st__2690#entry750372
I would be more concerned with partial wakelocks first, then kernel wakelocks second
enable restrictions and make sure your wifi isn't when not needed same with your Data. if you don't have 4g, turn on only CDMA data. went from 50% every 4 hours just to 15%

Facebook has always been a huge battery drain. Especially now that messenger is integrated into it. Friendcaster Pro is much better anyway

Exact same issue for me. I will try this.
I have had severe battery drain for a few days now. I disabled google now yesterday and that didn't change anything. My phone was constantly warm. Today, I turned airplane mode on and the battery still drained. It got down to 58%. I read somewhere in this forum that the google maps update was causing some battery drain so I uninstalled the update at 58% battery life. Three hours later I had 57% battery life. So, for now I can only assume that it was google maps that was consuming my battery. I will have to try updating maps again to make this a more concrete assumption.

The OS isn't always the reason for battery drain, many factors take into play.
How often you use the device.
Applications like widgets, email push.
Wi-Fi. If your not on it shut it down it else is always going to try to find a signal and drain battery.
Bluetooth. same with this.
Using the net.
Things like Google now, it's always running and trying to update info, shut it off of make intervals longer.
These are just some things to take into account, but at all use the phone different, and im not saying the OS doesn't drain but it solely isn't the only reason.
Hope this help.

I seem to be having the same problem. ..
Same here. With sync turned off, google now turned off, and most everything else that eats battery...
In the battery setting is shows that media is eating at least 25% battery.

I'm having the same issue. I read that the media drain could be caused by bad media files, but I didn't have any issues before this weird.
In my experience when you first update to a new samsung rom, the media using the battery is your phone updating the picasa albums...which stinks because it also eats your data like crazy if you are not on wifi and forget to turn off sync until wifi is available.
I've noticed faster than normal battery drain as well on my device. Normally by 4:30pm I'd be at 40-50%. Now I'm in the 20-30% range.
I'm going to try factory defaulting it soon and run it for a day or two. OR I might not even do that and just go directly to Task's AOKP or CM10.

I am going to flash to tasks tonight, not fond of what I've been reading about cm10.
But guys remember we all use our phones differently, take into account apps, usage, ect
Some days my battery lasts a bit longer than normal but I want using it as much.

i dont have any issues with battery drain, but i would suggest a full restore after upgrade. dont restore using titanium, just install through playstore. then report back but i doubt it will be an issue
Before everyone jumps ship, may want to try a new kernel. KT and a few others should work on the new release. Just make sure you choose one that works on JB TW and not ASOP.

I'm currently a kt kernel for jb twz.. but I'm not really complaining about my bat as I use my phone like a cheap hooker lol

I have the same problem.. After JB update there is huge battery drain. With average usage it drains almost 100%. Before update with heavy usage I was going through the day.
Maybe I should try KT kernel I don't know. I wiped all after updated, nothing saved from ICS.

Try kt kernel and change the governors to suit your usage

Same here,
It's seem the culprit is the android.process.media.
Each time i bootup,android.process.media is running for about 30 min, non-stop.
I already do a factory reset+sd formatting, but no succes.
With startup manager, i can block that process,but you need to be rooted .
I use the same settings as before i did'nt upgrade yet..i got it fully charge with no texting and calls the next 1hr its already 80%..i think i would try to cycle first my battery for 2 more days..then i'll see if it still have heavy drains..thanks for the response guyss.
Check out my overnight drian! from 1:30 to 10 the average drain is around 4% an hour, Losing about 20% overnight doing nothing.

I just got this phone the other day and immediately updated to jelly bean.Though I have nothing to compare it to my battery drain seems normal. I'm losing about 5% an hour but that is with some use (it's new so I'm playing with it a lot).
I did notice more drain the first day of use (may have been because I was using it a lot) and noticed maps was taking up quite a bit of the battery and I wasn't using it. So I uninstalled the updates for Maps and then re installed it. Battery drain seemed much better after that and now the maps app doesn't even show up in the battery report(before it was about 3rd and it seems kinda high on yours as well though you may be using it).
i'm noticing about the same battery consumption as the stock ICS rom. about 1~2% per hour when idle and sitting, 2~5% per hour listening to music over bluetooth with the screen off, and 5~10% per hour surfing the net and watching videos and stuff.
Well after doing probably 5 resets on my phone , it seems like everything is working fine . I was having issues with the battery drain ,internet not connecting, and phone calls taking 2 minutes to connect.
I was having issues with high battery usage as well after updating to JB.
I froze most every app and widget associated with AT&T and Samsung (with the exception of AllShare) and flashed KT747 kernel and set governor to ktoonservative (default settings).
I am really never a heavy user during the day, but with the same usage I had on ICS, I average 15.5 hours (with the phone at approx 15% when I shut it off to charge) - screen on time between 2.5 and 3 hours; call time between 45 min and 1.5 hrs; media (which seems to be a big battery hog) only about 6 minutes. I use bluetooth exclusively, so that radio is on all the time the phone is on. I keep sync and background data on, but only turn mobile data on as needed.

Solution for overnight battery drain.. Tested and working!!!

Whats up guys.. I have a one x and my battery just drains when i go to sleep... Around 20-23 percent.. Even with power saver on and all toggles off.. I tried many apps just to prevent this and still its the same result.. I heard about this app and i just want to share it to you.. Battery drain is down to 4-5 percent within a 10 hour period.. Thats just great!!! App is called Greenify and it hibernates your apps than drains battery.. Have a try and let me know.. Support the dev as well.. Cheerios!
https://play.google.com/store/apps/details?id=com.oasisfeng.greenify
Been using this for a while and it works well. Just understand what your 'greenifying' so you don't think apps are broken as a result.

Does your battery drain even with screen off at night too bro?
Thanks for sharing, this is sort of stuff I looking for
Anyway, I prefer to solve the problem without this kinda application first, I'll try it once I'm at dead end

Not hugely like yours but I use it among other things to get a good full day use out of my phone without limping towards end of the day.
I would use gsam to identify the app drain at night and greenify to help if you can't stop it with the app settings or a fresh install.

I used wake lock and saw google maps draining so much of my battery and I disabled it and so far 4 days battery is good... I mean it doesn't drain. Hope it works.
I use this Greenify with Deep Sleep battery saver at night, Wifi drains alot of unnecessary power in the night, deep sleep turns on wifi and sync every X hours. Managed to get 1 day and 11 hours with total of 3 hours screen time(i use my phone as a PDA not as a high performance device)

Not good battery times - wakelocks? (+screenshots)

Hello.
In my previous phone - HTC Sensation, when not use, battery takes 1-3% for an hour or even two. I buy Note 2 and I heard about great battery life (even with screen on - 6h-8h). But in my opinion it discharge faster than my previous phone, even when not in use. I post screenshoots, and can somebody told me where is the problem?
http://imgur.com/a/ChtrE
I think you should stop locus pro and turn off gps, just for tried if it's that drains battery
I would suggest an app called Greenify but it shouldn't be a solution. However, what I can suggest it for you to go into settings/data and disable the apps that tend to connect to the net in the background. Furthermore, install BBatteryStat and look for partial wake lock and see what apps keep waking your device. Once you understand what's using up resources you can mention them here and we can help you solve accordingly.

I use Greenify and BBS - see screenshots which i post. Maybe FB Chat is problem, because my last phone kill service in some time (because of ram), note 2 not kill, and app is always running as service.

Battery life

Just a general question, i have no problem with my devices battery life during useage, but whats annoying me is how much battery life i'm losing when the device is "asleep"!
i can lose between 10 and 25% battery when the device is asleep overnight, or while i'm at work.
this isnt a one off, it seems to happen most of the time, so i'm having to charge it every couple of days, rather then once or twice a week.
is this a general problem, or do i need to do a reset.
thanks
There are many apps found out there (some need root) that can track down what's eating the battery and or preventing device sleep. Google Search app is probably one of the culprits. I disabled it long ago.
If you're not rooted, try to disable some "bloatware" apps in your device settings > applications. .... If your rooted, freeze apps from self-starting using greenify app or remove with Titanium backup app. Just backup them first
I could go on and on, but at least some pointers where to start. Good luck
Have your wifi sleep when not in use. You may have some apps hijacking your bandwidth. You should only lose a few percent overnight...

I have the 8.4, fully stock and hardly a thing installed on it (it's like my 5th tablet for use) and I think its at 50% after idling for 15 days.
only thing that beats it so far is my Nook HD+, which probably idles for 4 months, literally.
having the same problem.
i do have google search in my pages. disabled it , gonna see how it goes ...
whats a good app to recommend that i can check out what is causing my device to wake while it should be asleep?
im rooted btw
