I can get to 8/8:30h screen on with power savings settings on and persus kernel HighPerf settings and 7/7:30h without power savings, stock rom, brightnes auto, no push notification no sync, wifi, battery 10%. Mostly gaming 60/70%,video,music usage.
[Galaxy Note II General] nitinmairothia:
I already did a factory reset,

I disabled Samsung link,

and now the battery is much better,

it was the main cause for my battery leak .

still I am shocked, how you guys can juice out 2 days from that little poor battery !
[Galaxy Note II General] tuxonhtc:
Rooted, de bloated, custom kernels :) You're just not utilizing the full potential if you're not rooting - calibrated screen, better battery life, fluidity, sound enhancement etc.

Either way even on stock, you're getting 6+ hours battery life right? Depends on usage, network coverage etc. obviously, but still?
[Galaxy Note II General] bluur:
Hi, my record so far 4 days without charging phone. 3g data off, sync off, wifi at least 1h per day on.

They really don't disappoint :D

First full charge out of the package.
[Galaxy Note II General] naeem86:
Wow..thats sick. It isnt too big?
[Galaxy Note II General] Simone:
At first I thought it was too thick and heavy but after a little while, I find the extra weight a little good and kinda gives a premium feel.

The thickness, I could get use to. You can still hold it comfortably.

But hey, for 3 times the stock Note 2 battery and just 39.99$ there is nothing to complain. :victory:
[Galaxy Note II General] 9ja Droid boy:
Guys this is what I get! I think my battery is draining fast...am using omega v16 ROM it was not like this when i was on stock ROM then it was far better.
[Galaxy Note II General] Simone:
Hi,

You have mobile network on and you have poor signal reception, sir. That may be one culprit.

Ok you are on which firmware 4.1.1 or 4.1.2 and did you experienced a faster battery drain on 4.1.2? ?
[Galaxy Note II General] 9ja Droid boy:
Please post the screenshot of your setting
[Galaxy Note II General] kaimyns:
Yes, in my opinion the battery drains much faster on JB 4.1.2.

Here's today's battery usage:
[Galaxy Note II General] Sajal Sharma:
Your battery life is awesome. I have never got a backup of more than 17hrs is use facebook app is this the reason (although I cant remove it) or is it due to 4.1.2. By the way you are on which firmware version.

I do get screen on time of more than 4hrs but even if I dont use it. I loose battery at a rate of 4-5%/hr. I am thinking to roll back to 4.1.1!
[Galaxy Note II General] naeem86:
here is mine. criskelo rom + saber kernel. using powersave and UV to -75. dont feel any difference with and without UV though. could have gone till 8h screen on time. but needed my phone the next day. so i charged it. xD
[Galaxy Note II General] timus911:
Wow! I've got to try that kernel.

Till now I've found Stock kernel to be the best for battery. I've tried perseus, redpill, uneak and terrabuzz. Out of these perseus works best(not better than stock though) for battery. Performance is the smoothest with uneak. but it drains almost 1.5 times that of perseus.

Stock-1d 10-20hours

Uneak 15-20h

Ive used ROMOW ROM throughout.

Me too am a stock kernel fan. But when i was installing criskelo rom, saber kernel was recommended in aroma. So i decided to give it a try. But this kernel is really good. Tried a lot of kernel. Only one that satisfied me was terrabuzz. But still it was not like stock one. Now i should install stock kernel on this rom and find out how much screen time i get.

[Galaxy Note II General] MarionCast:
100% agree! I don't have to worry about leaving the house with less than a full charge.

I'll post some of my own battery stats soon.
[Galaxy Note II General] GizmoFreak:
I tried leaving this beast alone for 8 hours. Came back and saw that it dropped only 8% in 8 hours. 1% an hour!

And this is on Stock Rom with no root or any such thing.

So was wondering that a moderate user can easily manage to get 2 days of battery life from this beast.
[Galaxy Note II General] oniwanbanshu:
Did you use the phone?
[Galaxy Note II General] MarionCast:
He did say he

left

the phone.

On that note, I think 1% drain while idle is still high, considering what is 1% for the Note II (with the 3300 mAh battery) is bigger than the usual 1%. But I guess that still is a good indicator of how impressive the battery is, battery drain or normal usage or heavy usage wise.
[Galaxy Note II General] yoniinfante:
correct* 3100 mAh battery
[Galaxy Note II General] oniwanbanshu:
my bad i read it wrong

personally i lose like 1% during the night in airplane mode
[Galaxy Note II General] fscherz:
Ok, I did today a battery rundown because I disliked that the note showed 100% for 2 hours after unplugging.

In the past I never came below 50% in my 18h days unplugged, I had once even 5h talk time in there.

I use just rooted stock ALJ1 and have push exchange mail, GPS, wifi & Bluetooth running all time. Great device, first after SII and note which worked always full day with a lot of reserves.!

I used first the device to sort my goole play crap and was playing Internet radio. I updated some apps and started to fill my SD card with some game downloads.

After that I started to download via wifi the picture cache of my SmugMug account. After some 4gb of 7k photos with you mostly screen on (I set it to long time out to keep it burning battery) I came now below 5%.

[Galaxy Note II General] timus911:
I get drained by 5 percent (from 100 to 95) with screen off in some 3 hours with uneak. Not so with other kernels.

Also I checked in BetterBatteryStats kworker/ many of these, are consuming maximum. And I know kworker has something to do with kernels. Why's that I'm getting so different results!? Same thing happened when I had uneak v1.7

What is it?
[Galaxy Note II General] ppn7:
An app named greenify. Just use it
[Galaxy Note II General] timus911:
Greenify WORKS!

Check my screenshot!

I never believed in task killers, but this is something else. It's perfect. I just have my power toggles, and network data speed monitor exempted from greenified.

And I'm still on uneak kernel. Wonder what those kworker things in BetterBatteryStats meant.

WOW! JUST WOW!
[Galaxy Note II General] D3_:
Greenify isn't really a task killer, those just kill the task and do nothing else.

Greenify stops things from running altogether as long as you're not using them. It's like an easier way of going into the app info in settings and disabling it whenever you're not using it. This way apps that you've greenified won't run at all unless you launch them. Facebook won't drain your battery anymore :P
[Galaxy Note II General] podface:
Stock everything except rooted... Samsung and Google sync on as well as whatsapp... wifi on 3g and gps was off... spent a good few hours watching mxplayer and youtube which was why battery was draining more after around 50%
[Galaxy Note II General] indie:
My battery life went from ok to very good in my opinion. Im on a stock pre rooted rom. I know screen time is nearly 3 hrs but I check the phone on regular intervals and kids sometimes watch a bit of netflix. I can get another day out if this. 3 days is Not bad !!!
[Galaxy Note II General] ppn7:
I think you have lot of wakelock that's avoid your phone to keep on deep sleep.
[Galaxy Note II General] R0B3RTF1SH3R:
greenify hibernates your stuff. it doesnt kill it or stop it from running. it just means. no resourses will be given to it. almost like its not allowed into cpu/ram/system. but is in a saved state

task killers however waste more battery than they are worth.

on

kill task cpu=drain

off

on. | decide need task.

load task back cpu=drain

load task killer + kill task again cpu=drain

.. that make sense?

[Galaxy Note II General] kinghu:
First discharge of ZeroLemon - looking good.

I purposely used it more than usual to try and drain the battery (browsing, eBay, Tapatalk and movies). I can see my usual light-intermediate usage pattern getting 6-7 days from this.

Dual SIMs don't seem to add much more drain either.

Nothing out of the ordinary. Standard battery yields 8 hours for many people, so this is simply 3x as much more-or-less.

Hey man !!! How did manage to get all that ,, i mean .. i need at least 2 batteries to make as half as you did !

I tried criskelo with saber kernel .. and see what i got ?
[Galaxy Note II General] naeem86:
I didnt do anything special. Like I said I underclocked to 1.2ghz and uv -75. U should check if ur phone is getting deep sleep. koz for me with saber kernel, even if the kernel is battery friendly, I found that lots of the time it was keeping my phone awake. Hope I helped.:)
[Galaxy Note II General] Jwan:
Oh thank you

But actually im not so comfortable with this undervolting ... i don't know it could be gross but i just think it's not ok for the phone to run it on a lower voltage as it designed to

So ... i guess im gonna back to my "SWIFT" ROM with the (6-7) hours screen-on .. well i didn't mind more but still not that bad

As far as I can see, great screen and idle times are achieved with excellent reception, 2G, wifi, disabling auto sync, and using chat software. I just got 2d of idle time with around 3h of screen on with auto brightness, no wifi, but the stuff given above and still have 50% battery. This is only while I change sim cards and get new broadband since I've just moved. No great shakes. It'll be back to a day of usage with 5h screen on time on 3G soon enough.

Camera snaps. Games. Tapatalk. Facebook. Viber. Texting. Videos. Internet browsing. Lots and lots of music and Wifi turned on all the time. Its very difficult to hammer the battery. Brightness set to Auto most of the time.
[Galaxy Note II General] timus911:
It really helps a lot if you choose the right modem. With custom ROMS, this is a big thing why people get inconsistent results. I am using ROMOW ROM, it came with perseus kernel. Since then I changed to red pill, uneak, saber... Right now on saber, I didn't feel any dramatic changes except that uneak offered smoothest interface with less battery. However all of these were sub power to the battery I used to get before getting rooted. That is while using everything stock. Wondering what it must be, I found a flashable. Tar file of the modem that came with the latest update in my country... and flashed it using Mobile Odin. And guess what, battery remained at 100% for the first 2hours that I didn't use the phone after unplugging. Almost equal or maybe better than stock kernel. Therefore it was never a kernel issue in my case, though they do effect battery life as well as performance in their own way. I'll post my screenshot proving this as soon as it discharges. :D
[Galaxy Note II General] Azinou:
Hello everyone !!!

Looking at your resulst of batterylife makes me wonder if I wasn't doing something wrong with my setting !

So my setting are the following :

Stock rom (latest version)

Mugen Power Battery (6400mah)

Batterylife : +/-40h with +/- 6h of screen display on

What's on : Wifi / GPS / 3G / Power save mode / Auto sync (work + private account in push --> +/- 200 mails / day in 3g cuz there is no wifi at work)

My average daily use : 2h of spotify with bluetooth on (for my BT headset - Other than for music, the BT is turned off), 2h of checking news on internet, +/-1h playing game (Age of empire, Candy Crush, Dead Trigger, ...), and social network + communication app (What's app and others)

Do you think my battery life is ok ? If not, what could I do to improve that WITHOUT changing my use ?
[Galaxy Note II General] naeem86:
its not bad if u have wifi/gps/3g on and looks like ur using the phone all the time. and ur playing too. but in my opinion u should be getting a little more like 9-10h of screen time. koz this battery is twice the normal one. for me with the normal battery i get like 6-7h screen on. i use my phone mainly for browsing the web, twitter and games. my phone is also always on 2g koz 3g sucks where i live. and i enable wifi only when browsing.
[Galaxy Note II General] Azinou:
Hmm, forgot to tell too, it's that my phone reception is awfully bad at home (something like 2 bars on the 5). The signal bar in my phone is, instead of the other posts, more yellow/grey than dark green -_-''' Could that be a reason of the battery drain ?

Is there a way to improve the reception ? :o
[Galaxy Note II General] naeem86:
in my opinion, the 3g syncing all the time is draining the battery. but still u should be getting more than 6h of screen time. u can improve reception by changing modem. but if ur using the latest me6 or mf2, dont mess with it. some people had probs messing with it. also try switching to 2g and see if it improves battery life. and also let ur phone sync like every 2hours.
[Galaxy Note II General] Azinou:
Could you explain how I could change modem ? And what is me6 or mf2 ? :o

I'll give a try to limit to 2G, should help I guess. But stopping the sync is not possible, at least, during work time... :(
[Galaxy Note II General] ppn7:
Please just try some day to put 2g instead of 3g and you will be fine. You don't need 3g for sync mail. Then you will get 7 hour screen time our maybe more.

If you need 3g for video or web browsing just toggle it please
