:D Same with me, it pinches me a lot to see my battery draining faster than before. And even I try to keep Hawk's eye on what's gulping my battery but so far I ll only blame it on new official samsung kernels.

But Well I guess Samsung has heard the cries of people and today I received two updates(OTA) mentioning Stability update. Hope this fixes this battery drain and other bugs. Also, now they included Google Play Music App in the update.

And after 4 hours of the update, battery life, I feel that it still draining quite fast but will test it in 2-3 days to be sure. Will update after few days of usage.

And thanks again for taking time to share your suggestions :)

Looks like the update was kinda dissapointed... It is quite battery draining after a day...

But I did try battery calibration as my solution, looks like is kinna sweet.

I charged my phone until 100% full this morning 11am and did battery calibration, now I still have 72% after listening music, surfing facebook, instagram, and twitter, with Wi-Fi on all the time and Auto Brightness on...

Anyone tried anything else? :)
[Galaxy Note II Q&A, Help & Troubleshooting] zevozki:
Im about to open thread but I saw yours so I decided to put my own issue.

I just upgraded my sofware from 4.1.1 to 4.1.2 France rom. Factory wipe before and after upgrade and first thing noted battery drain. I would specifically note SCREEN ON is eating my battery. 19 hours max i could get which comparing to old rom was day and half with exact same apps and settings.Who faced the same thing and who managed to resolve it?

Please see my battery screen shots
[Galaxy Note II Q&A, Help & Troubleshooting] ishaan_chd88:
Yep new updates doesn't resolve battery drain issue very much but its still better than before. During my sleep for around 8 hours, battery drain was just 2%, I was so happy but during normal usage, I still feel battery drain is little on higher side. I guess new updates do increase standby time but while on load it just doesn't performs like it used to be on 4.1.1.

That's sweet, you manage to get a lot of juice by those calibration. Currently Charging my phone and will see how it performs after a full charge cycle.
[Galaxy Note II Q&A, Help & Troubleshooting] ishaan_chd88:
Well, 4.1.2 do drains a lot of juice from battery when compared to 4.1.1. Almost every Note2 has been plagued with this after updating to 4.1.2. That's kinda shame for Samsung that their new updates are battery juice guzzler.

And to resolve this battery drain issue you can wait for samsung to fix this in new updates or you can root and then install custom kernels and roms. And also please go through takumibunta's posts above, He shared very nice points to resolve battery drain issue.
[Galaxy Note II Q&A, Help & Troubleshooting] aka_sirok:
have any of the ones who updated checked for sensors of movement and like that? i updated to avoid the SDS but after the first day I noticed that my phone was draining faster. I checked some things and some of them have been changed with the update (movement sensors is the only one that i can remember now) and now it last the same than before with some apps more such as xda app which it is said that drains also some battery

Hope it was just that the issue good luck! ;)

What is the method used for battery calibration?

---------- Post added at 10:23 PM ---------- Previous post was at 10:15 PM ----------

Can you advice where is this sensor menu so I can check?
[Galaxy Note II Q&A, Help & Troubleshooting] aka_sirok:
just go to movement in settings and click into the leters not into the "on/off"

U means motion to be turned off. Ok I did that now and let see the difference
[Galaxy Note II Q&A, Help & Troubleshooting] takumibunta:
Hi bro, I did some research before. 8 out of 10 people suggested do a battery calibration after flashing a new ROM. Well I tried and I think the results are good. I upgraded/flashed my firmwares four times since my first purchase. And I noticed it ate my battery when I flash a new firmware.

I did a battery calibration, it managed to hold more than 24 hours. I'm sorry I can't share my battery stats now because I just did calibration again to monitor my battery again so that I can ensure the accurate and 'real' result.

I'll keep you posted, let's see how the device go. Anyway, I still using a custom Kernel, did under-volt and using the ONE POWER GUARD app...

And 1 question, is your phone using all stock settings, ROM, and KERNEL??

---------- Post added at 04:22 PM ---------- Previous post was at 04:07 PM ----------

Oh yeah I almost forgot to share with you guys.

I found an app called Android Tweaker. It is free from market. But I managed to get a PRO versions which contains full functions.

For details just refer the Google Play's descriptions...

Back to topic, I used this app to do some tweaks on the battery section which are increasing the Wi-Fi scan interval and Increase Deep Sleep Battery Life...

I will see is it able to push my battery saving 'limit' even LOWER. Now I'm still charging my phone. I will wipe my battery stats and monitor again... It takes time, and I hope it will show more significant result of maintaining battery life.

Try this app with CAUTION! It might cause BOOTLOOP or get STUCK at Samsung logo!

DO A NANDROID BACKUP BEFORE USING THIS APP! JUST IN CASE. I HAVE WARNED YOU ALL...

See you guys soon... :)
[Galaxy Note II Q&A, Help & Troubleshooting] zevozki:
Lets first all agree in one thing to narrow down the source of the drainage. Is it the SCREEN ON is the eating your battery?

To answer your question im in stock rom and stock kernal with cf root only.

I know there are methods by using custom kernals and undervolting and supported apps.

Honestly I prefer to stable my stock rom and kernal battery usage first to last my battery more than 24 hours. So basically I like to work on stock because the majorty of the phones users are stock.

One thing I can try is battery calibration. Can you tell me the process?
[Galaxy Note II Q&A, Help & Troubleshooting] takumibunta:
Ok.

There is 2 options for your case.

Since you are using stock ROM & KERNEL, with ROOT access,

First option, I suggest you to use the ONE POWER GUARD app... The latest version is stable and there is a battery calibration function in the options.

Second option, download 'battery calibration' in the Google Play. Just for simple battery calibration only...

I STILL RECOMMEND ONE POWER GUARD. IT CAN OPTIMIZE YOUR KERNEL, ROM, WI-FI, 3G AND I/O SCHEDULER SO THAT TO MAINTAIN BATTERY LIFE. IT'S A NICE TRY.

Here is the step (The developer recommend us to follow these steps but not necessary)

THE FIRST AND SECOND STEP IS THE BATTERY CALIBRATION PROCESS

1. CHARGE your phone to 100%

2. Click on battery calibration button first (battery calibration app or ONE POWER GUARD app), then only plug off your charger.

THE THIRD AND FORTH STEP ARE NOT NECESSARY TO PERFORM, I TRIED AND I SUGGEST YOU TO DO THESE AS THEY CAN ASSURE YOUR BATTERY ACHIEVES THE MAXIMUM PERFORMANCE.

3. Drain your battery until it shut off completely, until you cannot switch on your phone...

4. CHARGE your phone again until full, without switching on your phone...

(Some people recommend to charge 4/5 hours to 'heat' the battery chemicals, I just forward their messages, I am not understand why to do that)

SORRY FOR MY BAD ENGLISH AND I HOPE YOU SATISFY MY REPLY...:)
[Galaxy Note II Q&A, Help & Troubleshooting] zevozki:
you did a great work bro. I will try what you adviced. 5stars
[Galaxy Note II Q&A, Help & Troubleshooting] takumibunta:
You are welcome. I understand how it feels when your battery is draining like hell. I will also try new things. Who knows? Maybe will find out something interesting :)

I am now trying the new app called Android Tweaker. So far, after my device is fully charged, I 'Skype' with my friends about 1 and a half hour, using XDA app about 1 hour, 'whatsapping' and watching music videos. They drained about 21% of battery in 5 hours. Unfortunately I rebooted my device to flash something and my battery stats had reset, it became inaccurate.

Looks like I have to wait until next round fully charge then I can make sure is the Android Tweaker helps me to reduce more battery usage.

But so far, I deep sleep my device about

6 hour. And I made several calls about 30 mins of total time. And I did set an alarm, I was too tired and I didn't hear it. The music was replaying about 30min :p Haha so embarrassing :D Now I still have 53% battery and I completed my charge at 2am in the morning.

According to my rough calculation, I have used my note 2 more than 11 hours (Including all the activities I mentioned above, and deep sleep time) ADD: Wi-Fi on all the time, motion on, and auto brightness on.

Looks like quite OK for me. But I still want to take a few days to observe few times so that I can provide a more accurate result to you all.

THANKS FOR YOUR APPRECIATION AND I WILL DO MY BEST. I'LL KEEP YOU POSTED BRO. :)
[Galaxy Note II Q&A, Help & Troubleshooting] zevozki:
Great analysis you have done so far. Im already started using one guard using one of preset optimization "daily mode" from this morning. I will monitor my battery till I see how much it can reach then I will post my comments.

Can you share me what best optimization mode you selected from the six and what you changed on it (one guard app). Your phone usage is similar to mine so I think your settings will suit me. Testing these all modes will require at least six days for testing so to save time and im a bit lazy :D I will use yours.

Keep it up im sure im not the only one who is trying your experience. There are viewers now they are getting benefit from your posts.
[Galaxy Note II Q&A, Help & Troubleshooting] takumibunta:
About the six modes, I had look through them and tested them shortly.

For me, the six modes are actually different settings (different CPU governors and I/O schedulers) only. For example, the power saving mode states that it will only 'run' the lowest CPU frequency, but yourself have to set the lowest frequency that you like.

Same as other modes, you will also have to set the CPU frequency.

Means that, the modes are just some 'guides' and they enable you to choose modes when you have set different settings.

I personally think they are no different since is just different 'original settings'. You are the boss who decide what CPU frequency to 'run' and what I/O scheduler to perform.

Now I'm using the custom mode. I can set the CPU frequency and I/O scheduler by my own. If you want to save more battery, you can always change the maximum frequency lower a bit (Original is 1.6Ghz).

*IF YOU DON'T UNDERSTAND WHY TO DO THIS, REPLY ME AND I CAN EXPLAIN AT THE NEW POST

About my I/O scheduler, I set 'ZEN' (This is an I/O scheduler from Perseus Kernel, I'm not sure other kernels/stock kernels has it or not)

For those who DON'T HAVE this I/O scheduler, you can choose 'sio' (I did some research and refer different xda posts, many people recommended use this I/O scheduler, maybe has benefits on performance or something, sorry I have forgotten it...) or you can use 'cfq' (So far I know this I/O scheduler can stabilize the performance or something)

*I PREFER YOU GO DO SOME RESEARCH ON THIS TOPIC IF YOU LIKE TO KNOW MORE, WHAT I EXPLAINED IS JUST BASED ON MY MEMORY THAT I READ THE POSTS, THEY ARE DEFINITELY WRONG/NOT REALLY CORRECT. I'M NOT AN EXPERT AND I JUST 'FOLLOW' PEOPLE'S RECOMMENDATIONS. AS THEY SUGGEST 'SIO' WOULD BE THE 'BEST' CHOICE. THE REASON I CHOOSE 'ZEN' BECAUSE IT COMBINES 'SIO' AND OTHER ONE I/O SCHEDULER. (I also forgot what is the other one)

I'm apologize for my bad English and I hope you could understand what I'm trying to explain. I'm not an expert, I just using the 'simple' way to explain...

For the others would like to help me to explain more clearly, welcome to correct my mistakes/help me elaborate more so that people could know the correct/more accurate answers...:)
[Galaxy Note II Q&A, Help & Troubleshooting] zevozki:
Your explanation was good enough. I could easy understand what said, dont worry bro.

I was comparing what you selected ZIN for IO schedular to mine and yes the stock kernal has three different choices NOOP, DEADLINE, CFQ. So guys who is reading please note the options to choose is vary from kernal to kernal, keep this in your mine.

I have read ablog referenced by the developer of this app to quick guid for using it. It was very helpful and good way to start to understand the process http://pinoyflare.blogspot.com/2013/01/one-power-battery-guard-100-working.html

I will try diffrent settings and its easy by the way dont afraid to give different limits and schedule. I will post later what is the optimum settings for longer battery life with accepted performance.

Cheers
[Galaxy Note II Q&A, Help & Troubleshooting] takumibunta:
The blog is good, it explains everything about the app.

I think this is the 'only' app that really works on saving batteries. Really sick of those battery app in the market which mostly of them are 'battety level reminder' only. When your battery is low, they only recommend you to switch off Wi-Fi or other ****s, which is really cause us inconvenience when we still need to use our phone.

ONE POWER GUARD, it's the 'real' battery optimization and battery saving app.

Hope those who are trying to use this app can see significant result of their battery life which I believe it will!

Good luck there! :D;)

Guys I just flashed the new rom N7100XXDMB2 France region after that I restore factory. Booom my note 2 battery is back like it was in 4.1.1

Iam writing now after first charge and using the phone heavliy to restore my data and setting my apps and still in 66%

No more battery drain. Note 2 is rock

You guys are trying too hard.

I downgraded to the oldest firmware lij (4.1.1)

Am I glad to have my old awesome battery life note again. Don't heed the naysayers who will scare you from 4.1.1.

If your memory check shows that you don't have the abnormal eff, I suggest downgrade.
[Galaxy Note II Q&A, Help & Troubleshooting] zevozki:
Guys I am telling you I gave up.

I have returned back to 4.1.1

I did tried many 4.1.2 and its waste.

Samsung should rethink many times before release any update. Shame

I feel sorry bro I told earlier that firmware was ok but after the second day I noticed draining exist.

If you welling to stay and for new one you can use one power battery as I wrote ealier. Otherwise switch back to 4.1.1 as I did

4) 8 mp primary camera with full HD

5) 2 mp secondry camera with 720p

6) full rooted JB with CWM and drivers free to download for developers/buyers (after a contract breach like HTC :P)

7) Innovative launcher that replaces oldschool drawer and home screen concept.

how can we make a custom rom on the easy way i dont mean from clockworkmod but trough the kitchen and is it good to use a linux version as OS on the computer
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] ThaiDai:
There is no easy way to a Custom Rom because you add customized mods or tweaks - that's always manual work and you need to learn for it.

If you use the kitchen (working for the N7000 since december - search for it) it'll give you a base: deodexed, zipaligned, etc.

Everything else is hard work - and risky if you do not know what you do to your device.

For the kitchen or other things you can use CygWin in Windows - but you always will have the performance impact and I would only call it a workaround.

If you want to really develop or build own Roms a Linux OS is the best environment to do it - but the question is: are you experienced with the "command-line-world". No Klicki-Bunti there.

[Android Themes] dhirend_6d:
Nice. Very useful tool. One has to batch rename the PNGs though first.

On Windows, if you want to batch rename, open command prompt (type cmd in search/run) and then go into the folder where all the PNGs that have to batch renamed are. Then just type this,

Replace the word prefix with the word you want to prefix all the PNGs with.

You can also add a postfix. Just place the postfix after %a.

I just use Faststone Photo Resizer for bulk renaming. :)

Correct. Most (if not all) factory default roms are odexed. As for installing a custom rom, I'd look at Supercharged Hatka if you want a stock look with tweaks. If you want an AOSP looking rom, go to Battery Plus (Something along the lines of that... Forgot the exact name)
