Hi guys!
This One X is very performing smartphone, games are really pretty... But I can stand that battery problem! I've tried so many rom, using setcpu for ondemand governor of the Tegra3... But I still not have so many battery life!
Can you guys suggest how rom, kernel or something else can save my battery?
Generic suggestions about this problem... Now I'm using Jdroid exodized 3.0.3 with bricked kernel v0.2, but battery is so draining... 63 % of battery with 1.37 hours of screen.. 4 h 22 min on it! =(
Hi!
I see a lot of people complaining about battery life, but if you take a look around you'll find the thread where people posted their battery usage. Me - I'm using rooted OneX running the stock ROM and am more than satisfied as far as battery life goes. I do 15 hours with ease. If I try to save it it usually lasts for more than 24 hours. Maybe you could try stock rom + root ... maybe a little underclock? I've been hearing underclock is quite the juice saver.
Hi,
I am the same I have tried custom Rom's but they claim to improve battery life but they just move the tegra 3 powersaving driver into the correct place!
I have a unlocked O2 HTC One X with O2 Rom and flashed battery fix and rooted the device!
Using this thread: http://forum.xda-developers.com/showthread.php?t=1597227
I have managed to setup a shortcut using widgets on the screen to select how many cores I want to use. I find that using one core clocked at 1.5GHz is fast enough and I don't have much lag! This has helped my battery massively! This is because O2 still haven't pushed through the HTC updates yet!
And also using this thread: http://forum.xda-developers.com/showthread.php?t=1630200
I flashed this using CMW and this has also helped.
I also find disabling some stock apps using App Managment in Settings, also using CPU spy from the Play Store and Battery Usage in settings. I can find the apps that use the most CPU power then uninstall or limit their usage (maybe using the internet instead of a dedicated app) this then has the phone stay in Deep Sleep for longer. I can easily get through 24hrs without having to try to save battery at all! I sometimes have almost got two days without charging!
Another tip is in the Usage app you can Restrict Background data over the network although when you connect to your WiFi it enables it again. Although it is meant to help save your Data it can also help your Battery Life.
Hope this helps!
Steven
Thanks for the answer!
I noticed that, in this Rom that I'm trying, I've the Screen that consume a lot of battery, even in the lowest brightness mode. Not using WiFi, 3g data, autosync, nothing, only a lot of text message received and sent. I think that this S-LCD2 consume a lot of battery or maybe the software of HTC, this time, is a loot poor of balance with this expensive hardware.
Do you think I can improve battery life with the tips that you said? I'm using this ROM right now http://forum.xda-developers.com/showthread.php?t=1597778.
Setting CPU to ondemand governor 304 mhz min and 1.5 ghz doesn't help me? I must disable some cores? I can give it a try, hope that this tips can be made in this AOSP Senseless Rom.

I'm asking myself [ and you ] if this screen consume really a lot amount of battery... Or there is some problem with my one x... Reaching the 3+ hours screen on is a good result, but in a 15 h battery day life, I hope... Maybe I can reach disabling a couple of processors
Don't worry about the screen, it will always take a lot of power whatever you do! It isn't worth messing with it.
You don't need to mess with the CPU although personally it does make a diffrence to the battery, I don't notice it too unless I am gaming!
Maybe an app is preventing your phone from going to deep sleep whilst the screen is off
Try using this app: https://play.google.com/store/apps/details?id=com.bvalosek.cpuspy&hl=en
If it says that your phone hasn't been in deep sleep, We need to try and find the culprit. Once you have done this maybe post back and I might be able to help you sort this out! It took me a while as I had this problem but it was definatly worth the effort!
Try looking in battery in the settings and see if there are any apps that are using a lot of power (maybe take a screen shot) and also try in Data Usage, there maybe apps using the Internet whilst you aren't using the phone. This also wastes the battery. If you restrict background usage (only on certain apps) it will only use the Internet in the background whilst you are connected to wifi only. Facebook is a good example!
Hope this helps

If you don't understand anything please say, I know my explanations are awful but I will try my best! I think I have changed everything here to fit your rom!
The rom itself although you or the developer know this but the overall system could be causing a problem! (just a theory!)

You're too fine with me steven, thanks!
I've downloaded Cpu Spy and it says that my one x has been in deep sleep for 70 % of time, so there is no problem with some apps doing something during screen off. My problem is that when I'm using all 4 cores, without internet via wifi or 3g, without autosync, nothing at all, and screen at lowest brightness, there is still a drastic battery drain while I'm using only Message app a lot. I don't wanna think that my HOX have a fault battery, but how can I test and prove it ? I don't know if there is a program, app or test for doing this thing.
Now I'm with that ROM Senseless AOSP ICS, I will try next charge with two cores actives only and view how much I can stay with that SetCpu settings. I'm using this settings: 101% Battery <, CPU Max 1Ghz to 51Mhz and priority 100, governor ondemand ; screen off, CPU Max 1Ghz to 200 mhz and priority 100, governor ondemand. I'll give you the result soon.
you need to give it time to settle the battery mate. i manage to go a day or two and have like 3 hours screen on time and that is with everything on. if you need any help send me a PM mate and i see what i can do to help you. and i would not use SetCpu for now i am using No-Frills. And switch from ondemand to Interactive. and that is with 1.5Ghz as max and 100mhz mininum

I agree that you should not use set CPU although you are best using ondemand as that is only using the amount of power you need, interactive keeps the speed high to increase the overall speed. (not good for battery life) also maybe, my mothers Samsung Galaxy S2 had battery problems and she got 6hrs of battery out of her phone at max, she always carried her charger around.
I calibrated the battery without using any software, I just fully charged the device and left video/audio/maps on to get rid of the battery as fast as I could and then fully charged the device. All I am trying to say is give this a shot (I did this when I first got my phone) she now gets on average 2days battery life! I know that it can take ages but it is defiantly worth the effort!
Hope this helps
Steven
Also, how do you find that ROM it looks great. I think I might try it!

Hello,
I have a high battery drain because of "Android System". I lose about 3-5% per hour of my battery in idle state. I turn screen off and didn't use it.
I'm using Slim ICS ROM with franco kernel #174.
Badass Battery shows me that following included processes are in Android-System:
Code:
com.android.systemui
system
android:ui
com.tmobile.themechooser
surfaceflinger
com.android.settings
servicemanager
So anybody know what's the problem here?
I'm already disabled Google Photo Sync, NFC and GPS because I didn't need that. Also googling for the problem doesn't help.
Hope you can help, thanks!

Again, I've mentioned this twice today: Bullsh**, I don't mean to be disshonouring, or anything, but please, give proper answers,. It's all good, that you want to help, but only with proper and correct answers.
Right, back to topic;
Go into your dev. settings, and uncheck everything that doesn't need to be checked (Stay Awake, Strict mode, etc.) Undervolt the CPU, that should save a ton of battery charge, and underclock to 900-920 MHz, that is definitly enough, on a dual-core
Thanks for your answer =)
I think my phone is already undervolted through Smartreflex in francos app and I also tried underclocking by setting max cpu to 1036 Mhz (instead of 1200 Mhz).
The problem disappeared after 1-2 charges (don't ask me why..).
And now after flashing Slim ICS 3.9, battery time seems to be ok (for me at least).
Per hour in idle state the phone consumes ca. 2-3%.
I ask myself how do others get 1% drain over night. Is that even possible? Tried very much kernels (franco, trinity, glados and leankernel) and didn't even get near that.
Any tips?
OP Im glad you mentioned the issues went away after a few charges. this has been an issue for some who do not believe that a few charge cycles does anything. well im with you as i always see things sort of "settle down" after a few days of flashing a new rom.
I have the same problem on my Nexus S.
The process consuming battery is surfaceflinger. I can see it on battery screen before the name change to Android System.

Just wipe Battery stets after flashing. It needs few complete chargings to calibrate the battery.
There are also many apps in the market for this

Yes, it is possible. I get 1 or 2% drain overnight with wifi and mobile data disabled, and up to 5 to 6% if mobile data is enabled overnight.
My record with it is 1 day and 20 hours from 100% to 3%.
I had a LG Optimus Black before and didn't last a day. I'm loving this Galaxy Nexus.

I would like to achieve battery drain like that, seems like what it should be.
I am running AOKP Build 2 and I feel like my battery life is ok but not great. I let my phone sit overnight last night with sync off, but LTE on and it drained roughly 4% an hour. I actually turned off LTE in the middle of the night to see if there would be a difference, and no, it drained at the same speed on 3G as well. I live in an area with pretty good reception actually, GSam says I spend the vast majority of my time with a signal strength of 4/5.
GSam reported that roughly 34% of my battery drain overnight was due to Phone Radio. Another 52% was due to app usage. Drilling into that it tells me that over 40% of the battery drain from apps came from "Android System", "Phone" and "Kernel". Under Android System, which was by far the greatest drain of the apps, it only kept the phone awake 1m18s overnight so that doesn't seem excessive. However, I'm confused as to why, with a good signal/connection my battery would drain at nearly 4% an hour whether connected to LTE or CDMA. Unless the radios in this device are poor, I have a hard time believing there isn't a way to fix this without using something like Juice Defender.
I can't recall because it's been so long, but I don't really remember any ICS ROMs draining this fast. I'm on a clean install of AOKP B2 and I've tried a few different kernels with the same results. Any ideas anyone?
So I wanted to let you all know that after trying a few different ROM/Kernel combinations all with similar idle battery drain, I installed the latest (9/21) CM10 nightly and I only lost about 10-12% overnight last night connected to LTE. That is a much better drain than the 30% or so I was seeing previously. Not sure why but my phone just hasn't been handling the latest AOKP builds very well. I am afraid to try a different kernel right now as I'm leaving town tomorrow for most of the week so I'll leave it as is until I get home next weekend, and see if I get this good of battery life with the latest Leankernel.
Surfaceflinger
The same happens to me, this app appear in BetterBattery stats, Surfaceflinger appear as the culprit of my 45%+ battery consumption caused by Android Sys
When I first rooted my phone (xperia S) I noticed an 31%+ energy consumption by Android Sys, I reflashed and re-rooted and stoped for 2 weeks or so, now 2 days ago I woke up to find that 81% of the battery is being drained by Android Sys, then it lowered to 31-43%. I noticed that when I refreshed the stock "Battery" app ,"Surfaceflinger appear for a moment, I seem that I confirmed with the BetterBatteryStats, Surfacaflinger appears at the top.
Why is this happening? Can something be done about it?
PS: I cannot change kernel, bootloader is locked...
Surfaceflinger and android.process.acore are top battery drainer. I mean how to make them not sucking on battery?
I've used cm9 and aokp the past month and tried the stock Kernels that come with it and Franco's. One thing is for certain. No matter combination I get horrible battery life. If I run stock android with my extended battery including various Widgets I get 24 hours battery life pretty easily. Moderate usage and some heavy usage. With cm9 I'm getting maybe 15-16 hrs with aokp maybe 8-9 hers and I'm using Franco's kernel right now. I don't understand this. People talk about how much better the battery life is with various ROMS than stock but I'm not getting it. I'm getting like half the battery life I was before. Any ideas?
Sent from my Galaxy Nexus using Tapatalk 2
I can relate to you. Was in CM9 and Franko's kernel and as you said, horrible battery life. I went back to stock but this time I did not install apps thar would require services running (well I have to run WhatsApp so that's the only one running besides default abdroid services).
I am seeing better battery life this way.
The next step would be to install CM9 and restore all my apps to see if I can replicate the same battery life.

you need to find out what apps are keeping your phone from sleeping dude its not the ROM or Kernel if you want to find out you can use better battery stats or just read the permissions on your apps otherwise its probably cause your on your phone too much with the screen on first show use a usage screen shot then how many apps you have we can narrow it down

I used that better battery stats app and apparently there was audio something (sorry can't remember the exact words) causing partial wakelocks, read some google search results and disabled the lock screen sound in aokp and it went away, go figure?
I swear my battery life is better with the kernel that comes with AOKP rather than franco, which was a bummer since I'd just bought the franco updater app, perhaps just my imagination or maybe something just needs to be tweaked
Well, this has pretty much nothing to do with the ROMs/kernels, you flash to the device. If you use the device for heavy gaming, you use loads of apps etc. the battery life will obviously be bad, because the CPU needs the according CPU clock speed...
Underclock the CPU, or better: Get AnTuTu CPU Master pro, and set the profiles, underclock screen off, to 700 MHz, and every other proile, where you do not neccessarily need the device to that speed, not below, otherwise it will just crash... That way you have the best battery life, for your usage, so basically, every time you switch the device's screen off, it will save a hell of a load of battery
Under clocking doesn't do much for battery life contrary to popular belief. It just increases the time it takes to process a task. It might take 1s at 1.2ghz vs 1.8s at 800ghz to complete a given task for example. So yes the cpu will run at lower speed and voltage but it still also take longer to return to idle.

Well, I don't really mean to break this, because it is right, but not completely...
Underclocking & undervolting, when the device is not in use (Screen off) saves loads of battery...
And because it's a dual-core, it takes mostly just as long to open an app at 700 MHz, as when you're doing it at stock clock speed, or voltage or higher.. So, in that case...

Not sure how this wouldn't have to do with the different ROMS and kernels since I stated what battery life I was getting with stock vs using a custom kernel and ROMS. I'm giving a comparison of my battery on each with the same usasge and they are different.

Hi guys,
I recently switched to CM 10 (Android 4.1.2) and the battery life is significantly lower than what I had on the stock ROM and the new Sense UI... I guess.
My phone won't run longer than 10-15 hours a day with normal usage, which means Wi-fi and 3G always on, screen on automatic brightness being used for about 1 hour in total (for one charge). However Android OS, Cell Standby and Phone Idle still account for the most battery usage, which I find weird. I have no wakelocks and my device goes to deep sleep when not used.
Is this normal behavior with the new Cyanogenmod and Jellybean or are my expectations too high? I already read most threads concerning battery life, but most of them discuss problems such as wakelocks or similar issues. My question relates to the normal behavior of CM 10.
I am grateful for all replies on the matter or personal experiences.
It's known that CM10 battery life is worse than stock JB. You can try different kernels and different governors, but it's a trade-off between life and performance.

I don't understand, I thought that CM is stripped out of unnecessary background processes and apps. As long as I'm not using any CPU or GPU intensive apps like games it should consume less battery than the stock ROM. Is there something I'm missing?
Maybe the updated kernel and drivers give better power effeciency. When the JB kernel source is released, hopefully CM10 and other AOSP ROMs will also improve.
You were saying about on screen time?
Sent from my faster than SGS3 HOX.
CM 10 really uses a lot of battery but of you could switch off wifi and 3g when not using, and clearing all the apps frequently in the recent menu may help... My battery then lasts from about the start of the day till night though the batterys now quite old.

i got a weird battery life yesterday, i was walking from work to home, i started watching videos on youtube, looked at the battery, 31%, after few videos looked again, still 31%, i walked 41 mins with a total of 9% of battery drain, i also played a game for about 25 mins, it was a really battery life.

Maybe the updated kernel and drivers give better power effeciency. When the JB kernel source is released, hopefully CM10 and other AOSP ROMs will also improve.

That's pretty much my battery life as well. Regarding age, I'm really concerned, as I'm not able to open the phone and just replace it. But I guess that much better smartphones will come along before I consider getting a new battery and it won't be worth it any more.

I get that sometimes as well. I pick up the phone a couple of times and the battery is always at, say, 50%. Then, a couple of hours later I read a message and it suddenly jumps to 41 or lower. But from what I've read that's normal and no cause of concern.

I heard what causes the CM10 to have such an awful battery life is something that was supposed to save power when you lock your phone [Which is normally quiet often] and actually causes it to depelt, so it obvoiusly doesn't affect screen time
CM10 is a horrible ROM, get something else... I used LiquidSmooth for a while, it's a great ROM
Now running ParanoidAndroid 2.53
Btw, Stock ROM had a wonderful battery life, I only realize that now ... lots of ROMs can't reach that much

That's exactly what I did, flashed the old RUU and installed all updates. I don't know how the guys from HTC managed to do it, but the battery life on Android 4.1.1 and Sense 4+ is AMAZING. I easily get 24 hours with normal usage, over 2 days if I'm really careful.
This is what I got during a night sleep with cm 10.
I installed it yesterday so its kinda new tot me. What causes this?

Probably some nasty wakelocks. Install with wipe/factory reset if you didn't so already. Then try betterbatterystats (search xda) to find out what is causing wakelocks.
Hi! Guys, Well I bought my Note 2 in November 2012 with Multi Window update already Installed. Everything was So smooth and awesome until the Christmas update in India. My battery started draining comparatively fast but still not a huge change. But handset became little slow. That I consider Negligible. But then come the Jan update which I feel was quickly done to rectify that "root permission by default issue" like in S3. And after that am facing Issues like fast battery drain like previously when I used to sleep my battery drop by 1% only but for same amount of time when I check on waking up it had gone down by 7-8% and haven't installed any new apps so far.
But the biggest issue I face is that Note 2 won't charge sometimes then I have to restart my mobile and then it charges again and it happens quite often. Like I will face this 3-4 times in between 10 cycles of charging.
My Note 2 is not rooted for now.
Also a issue I have noticed that sometimes my camera images becomes corrupt on its own. This happened only 2 times though.
So, guys do share your advice/views on this.
Thanks
Also I have noticed that some times blue led blinks on its own. without any notification. And Smart alert doesn't go off, faced this rarely though.

You can TRY flash the latest FIRMWARE using ODIN... I'm not sure whether it will solve the battery drain issue but you cab try, but I personally think it's not too big difference...
For the battery drain issue, here is my suggestions:
1. Flash CUSTOM KERNEL, do undervolting your device, which I believe will significantly reduce the power usage...
2. Try use ONE POWER GUARD apk, I optimize the kernel and CPU, and other stuffs (Wi-Fi, 3G...) It's available in Google Play.
3. (I think you really need this if your battery is behaving as you mentioned) Do battery calibration, download BATTERY CALIBRATION in Google Play, charge your phone to 100%, open the app and tap BATTERY CALIBRATION. After that drain your battery until it switch off automatically, and charge your phone to 100% again in off mode...
And I'm so sorry to tell you that you need ROOT access then you only can try these solutions...
I also had battery drain issue before, but I found out that if you use all my suggestions, the battery life does INCREASE!
I flashed Perseus Kernel and undervolted my device using SET CPU... Battery drains about 6-8% in an hour with my Wi-Fi ON, Auto Brightness, and without turning off the screen to surf the WEB!
After that, I found out that my battery also drains about 7-10% after a whole night deep sleep, when I wake up in the morning.
I found the second solution, which is using the ONE POWER GUARD. Now, the battery life IMPROVES EVEN MORE! Now when I wake up to check my device, a whole night sleep is just draining 2-3% the most!
Thirdly, I accidentally found the Battery Calibration app in the Google Play...
I tried that but no difference, since you only need to use it when your battery starts to have problem (Others comment)
You can try this, I saw many good feetbacks from many users that it helps...
Now, I open my Wi-Fi all the time with Auto Brightness. I enjoy my music, video, web ever day. I finished charge my phone in 9 am yesterday, and now, I still have 51% to use XDA app to write this post Amazing isn't it!
ROOT YOUR PHONE, IT DEFINITELY WORTH TO SAVE YOUR BATTERY BY USING THESE SOLUTIONS... (My Opinion)
TRY THEM OUT BRO! GOOD LUCK

Thanks a lot for your suggestions.Will definitely gonna try these. And will surely root my phone once I get proper time to perform this ..
Yep I also think that these are cause of new kernel which samsung released hurriedly.
Will Contact Samsung and see what they gonna say.
And I checked my battery drain today with wifi & 3g off, Screen rotation off, sync disabled,location disabled,All motion disabled, pen detection battery save on but still ate my 5% of battery that too in sleep mode. Samsung's New updates have lot of bugs.
will root my mobile and will see how it performs. Thanks again for your valuable suggestion.

A lot of people complain of battery drain with their latest updates. I'm personally not too happy with it, but my device still lasts a whole day. I'll give Samsung another update to fix the issue. If they don't, I'm going back to 4.1.1 because I never had any issues there.
I've done a hard reset and nothing. Next time I'll try clearing all data and everything off of my storage and we'll see. Hopefully Samsung will fix this.

Indeed Samsung's new update has numerous bugs, hope they will fix it soon. 4.1.1 was Flawless.
And I doubt that clearing all the data will help as battery drain will be related to the new kernel and OS.
Let's see when will Samsung gonna release there new update to fix these issues.
I flashed the new MA6 French firmware, seems many MODs and Custom ROMs are released/updated based on this firmware...
I will see how it goes, I still using Perseus kernel, and ONE POWER GUARD.
So far, the results are not sure because now I have only tested it for 2 hours...
Hope it doesn't drain much battery... :laugh:

It's kinna pain in the ass to see battery drops faster than the first time I used the device.

I will also continue to monitor my device after flashed the new MA6 French firmware...

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?

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.

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.
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!

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??

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...

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?

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)

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 Haha so embarrassing 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.
