Per hour or whole night overall 2%? How about air mode off?

Any idea what could be causing Android OS to use more juice than android system and anything else besides screen? Mine's been this way since day1 (have had it for almost a week). I have now disabled most of samsung bloatware with little to no effect. Only things syncing should be s-note, google stuff and email.

I should add that with Juice Defender Ultimate on, the drain is about 1% per hour when screen off. Without that app it's 2-2.2% per hour

I'm still happy with the battery life in actual use, but the stand-by life worries me a bit :eek:
[Galaxy Note II General] dzontra11:
Around 7 % for 8 h...thats normal i think.
[Galaxy Note II General] DanDroidian:
Stock with 3G on all day, some WiFi...
[Galaxy Note II General] Gnarfsan:
Your calculations are wrong. Most of the other apps you see in there ran for 2 hours more than maps.

But if I let it run, it will normally have a percentage thats twice that of the screen during a day of normal usage.

My battery has been dieing fast these days and I am only using wifi. I have disabled gyro and 95% of the smart functions. As you can see in the picture below the android os is number 1 crazy and if I am lucky getting 5 hours of display time. Does anyone have any ideals what I could change or programs to use ? Thanks in advace

Really curious about finding the battery life for the people who have the N7105 model with LTE on. Otherwise, HSPA only looks great.

I have just got this phone there was some battery it in so am I right in thinking I should leave it die then chsrge to 100 percent

Get BetterBatteryStats (Available somewhere on the XDA forums if you search) and check for wakelocks after you get battery drain like that

Nah, on newer batteries like the ones in smartphones now you don't need to let the battery die (in fact I'm pretty sure it's bad for the battery if you let it completely die) before charging.
[Galaxy Note II General] berryc:
I've had mine for 3 weeks and I find the battery brilliant, always on Internet, listening to pod casts, email and messaging easy lasts me a day and a half.
[Galaxy Note II General] sway40:
Looks like you have a rogue app, think of what you installed that past few days and uninstall those. Like the other member said use betterbatterystats it works well in telling you what's up, your android os should be around 5to8 though. Have you simply tried restarting your phone, turn it off for a min or so, may just be some core app stuck running.

Edit: I still haven't got my note yet but I'd give my left nut for that screen on time, I know you note people get more but just sayin

Easily the best battery life of any touch screen smartphone I've had, and I've had a lot. 61% with wifi on all day and apps and web running constantly. Display was at about 30% brightness throughout the day.
[Galaxy Note II General] DanDroidian:
Has anyone noticed if the battery life was better or worse before/after rooting their BEAST?

If you did notice a difference, do tell!
[Galaxy Note II General] sohebq:
rooting alone has no impact on the battery life unless you freeze some apps or change kernal

[Galaxy Note II General] rtz619:
Amazing battery life.

Only used for calls, sms, What'sapp and browsing. But still 3 days and still going.
[Galaxy Note II General] dnahelix:
Really a beast.. keeps running. With the routine use as my previous phone this is what I got. .beyond 2 days.
[Galaxy Note II General] DanDroidian:
Damn, this phone really is a BEAST!

Almost 9 1/2 hours of screen time, and that's after I unplugged it at night and let it drain for about 9 hours while I slept the night before!

I used it all day, using the internet, Tapatalk, downloading new apps, setting up new widgets... Mostly on WiFi, but also used 3G some too.

And here are 2 screen shots I took right when I woke up after letting it drain for about 9 hours. (I did switch it to 2G and "Power saving" mode while sleeping just to let it save more battery power for the next day. No need to do that unless I'm going on a long trip or something though.)....
[Galaxy Note II General] dzontra11:
I dont understand how is possible that you have 9 1/2h of screen.Rooted..your set up?
[Galaxy Note II General] DanDroidian:
I agree, almost unbelievable!

I didn't play any games that day, but I was downloading a lot and doing a lot of browsing with the internet. I was inside restaurants the whole time, so my screen was only about 20% bright most of the time, or less once it got darker.

Stock XXALJ3 with no mods at all.

Features like motions, Google Voice ALWAYS listening were off (auto-rotate was on, of course).

Gmail, Facebook, FourSquare, DropBox, WhatsApp, Viber, etc were all on and synched.

Made a few calls, but mostly using it as a browser the whole time and checking out different apps and various browsers (of which I liked the stock browser the best, in case you were wondering...)

I would call it medium-heavy usage, since the only things I didn't do were play games....

And, since it might be relative, when I bought the phone it had about half a charge on it. I used it for several hours before charging it to 100% while on. After that, I let it drain to 0% and die and then charged it fully to 100% while powered off, which I did 2 more times. Just so you know.. Also, it takes LESS than 2 1/2 hours to charge from 0% to 100% while powered off. That's fast! !

(If you saw my other posts from yesterday, you'd see I asked if rooting my Note 2 would have ANY effect on my battery life, and the answer I got from many was NO. I was just as surprised as you are to see over 9 hours of screen on time, ESPECIALLY because I had already let it drain for almost 9 hours while I slept the night before!)

I'm almost worried that rooting it or deleting certain ROM apps will somehow make the battery drain faster than it does now.
[Galaxy Note II General] dzontra11:
I know about root ,,,i just was thinking maybe you set some costume kernel ,,beceuse kernel is most important for battery life(almost most important).

Anyway,,,only once i got 7 h screen but most of the time i got "only" 6 and half screen on.
[Galaxy Note II General] DanDroidian:
Good questions, but stock kernel....
[Galaxy Note II General] dzontra11:
Damn....
[Galaxy Note II General] jujuburi:
It's a wrong idea that you can have good battery life with custom kernel only. Stock kernels can also achieve great results, as you can see from the results above, I have also posted 9+ hours screen on time twice in this thread.

But being said that, everyone has their own method of using, how many apps you have installed and those related factors, so no need to worry if you're having less screen on time.
[Galaxy Note II General] dzontra11:
I am not saying that just kernel can improve

battery but can help a lot..for sure.

We talking about 2 h more juice from yours devices...so i want to know how to do that...for sure my apps is not reason to have less juice.
[Galaxy Note II General] jujuburi:
Then maybe your connectivity is. You may leave your Data or WiFi on at nights and Sync some apps randomly. One more thing, long standby means less screen on time. If you have standby of 3 days then 6-7 hours screen on is amazing. Twice I achieved 9 hours screen on time and on both occasions my standby was around 1-1.5 days. More standby means more overnight battery drainage, so lesser screen on time.
[Galaxy Note II General] dzontra11:
Nope 33 h and 6 h screen on...over night i lose only 2% with air mode and battery saving on.

im confused on how many of you are saying the battery life is great.

Can anyone help me on how to improve my battery? I struggle to get through half a day without charging it

You must have some sort of wakelock, have you tried betterbatterystats to check wakelocks?

@raymun

see you have proved again, juice defender is a just a crap battery drainer app a d nothing else. it drains more battery than saving and you can easily see that from your stats. Remove it first man. The 2nd wakelock is related to audio being played. Third one is related to a mms app

[Galaxy Note II General] Raymun:

[Galaxy Note II General] jiicee:
I can happily report that I have fixed my "android os" -caused battery drain. Now the phone drains 0.4-1% per hour when idle and "Android OS" battery usage is where it should be (well below screen, and below android system).

The culprit? Apparently some freak compatibility issue with my wifi router (Telewell ea515) and the phone. I did googling for several days and apparently there are quite a bit of folks with android 4.0-> who have this compatibility bug(with different routers, it's not just telewell specific). Some people have great battery life home and horrible at work, and vice versa. I changed my wifi router back to my good old linksys wrt54g and that instantly fixed the issues. Same settings, no problems.

Weird? Yes. Solved? Yes. :cool:

Now I just gotta find a new wifi-N router that's known to work with this phone. Anyone can recommend a great modern wifi router that they have with this phone without the battery drain issue? Thanks.

i finally decided to give my battery a bit challange. below are two attached pics.

7h screen on: causual wifi/data use, maps disabled, facebook app removed.

5 hr screen on: data on all the time, maps on all the time and facebook app running

other than these 3 basic things, all other useage remained same. Hence those who are not getting higher screen on time should:

never ever let the wifi and data on all the time, only turn it on when u need. This will make a hugeeee difference. Some people have posted bbs stats. In the kernal wakelock screenshot, the multipdp and 12hsc wakelocks are related to data and these only arrive if you keep wifi or 3g on all the time.

If possible remove both facebook and maps app. Plus some other ones which you don,t use.

Doing this will save at least 2-3 hrs of battery juice.

Same here...that damn facebook app drain battery a lot.
[Galaxy Note II General] jiicee:
I disagree having to turn off wifi and 3g. What's the point of a smartphone if you can't have sync running in background? :confused:

For me changing my wifi router gave battery life back (read a few posts above), but I don't use facebook and rarely use maps. I do have full gmail and calendar sync on, also rss.

Hey guys,

Im not to sure if its just me being paranoid or i am also not experiencing the awesome batt life that other NOTE 2 users are having.. But my phone doesnt seem to be doing that well...

I fully Charged the phone to 100%, played games and watched video till 70%.. That all seemed fine... But then i locked my phone at 3am and slept till 10am to wake up to a loss of 20%?!?!

Is this normal?? Should i go down to the service center??

Thanks in advance :)

Fair enough, at least keeping it on when at workplace or home(in good wifi coverage) shouldn't be an issue ever. If it is then some app or os bug is raping the battery and those are fixable. When things are working, there should be no reason to keep the syncs off unless you are going camping or smth and need the battery to last for many many days :)

I am quite sensible with my set-up though, with autosync around 3hrs, brightness 40-50%, 1min timeout and all touch feedback off.

Any wakelocks I should be concerned about?
[Galaxy Note II General] sohebq:
^^

can you see the yellow bars in your signals line in the battery stats? yes that,s when wakelocks actually arrived due to poor signals. The top 2 wakelocks in the kernal wakelocks is due to that. Partial wakelocks are fine. It's all your choice man that how you want to use the phone and this is what i love about android.

Yeah maps I know, it's because I use latitude with my family members, it's a pretty nice feature. The media handle wakelock could be the fm radio? Or youtube? Do I really have to manually kill active processes from settings? Does it interfere with sync jobs working invisible to the user view? Does not android manage to its own needs active processes and ram?

The mobile signal seems not to be a problem, there's full hsdpa+ coverage here

Talkin about the second highlight maybe browsing or using youtube? if It was approximately 20-15 hours before the screenshot time, i was probably browsing or using youtube.. maybe this last one made the phone keep awake..? The no signal part is for the airplane mode during night

[Galaxy Note II General] jujuburi:
Yes, Android does manage to run/start apps or any jobs automatically when needed, but NO, it will NOT kill any app/process you turned on, you have to manually end it what you started.

Just end all processes from Task Manager (obviously you know you can achieve it by pressing and holding the home button).

And just fyi, Latitude is huge battery drainer. You of course will use it if you need it but just thought would inform you.

Also your phone signal is weak sometimes! I am quite sure that you are on 3G however, if you don't need it you could switch to 2G and have solid signal and battery also.
