So I rooted my phone and flashed the Blazer ROM. Everything flashed well and I am loving the look of this ROM. My only issue is that now my battery is draining very fast. It seems to be going down faster than before the flash. I tried calibrating the battery with one of the marketplace apps, but it hasn't done much. One of the main reasons for flashing was to improve the battery life. I am looking for any suggestions on what I can do? Is there any point in trying to re-flash the rom? Any help will be appreciated.
Thank you in advance!
Give it a few charging cycles for everything to settle in....also download better battery stats and check for possible wakelocks

I had the same problem with this version of Blazer Rom. After my 4th charging cycle I had to get off it. I couldn't get a whole day use. For some reason battery drained hella fast. I'm back on stock rooted now. No rom has given me better battery life than when I'm on the stock one so far. I usually give the rom about 4/5 days to see any improvements. If too many bugs or battery drain I'll get off it sooner than that.
OK thanks! I guess I will try and give it another couple of days and see if it improves. If not I'll consider switching ROMs. Sorry but what is a wakelock? I'm still pretty new with all of this.
had same issue i just flashed rom three times and since then ive been getting a good 16 to 20 hours on one charge.
had the same issue, i was at work and charged my phone, one our latter my battery was down 20 percent went back to stock root.
Im also curious, what's wakelock?

wakelock is a term meaning an app I going rogue keeping your kernel awake. if you use bettery battery stats and cpu spy you can see what keeps waking your phone up when its supposed to be in a deep sleep. btw when charging it doesn't go into deep sleep. so it may give you a weird result if you check after a charge. also do not spend any money on battery calibration apps. every app I have come across tries to calibrate by deleting battery stats. which has been proven to do nothing. just a heads up dude.

A kernel mechanism for Android power management. When a thread holds a wakelock, the kernel will refrain from entering a low-power state.
Basically, an app or process is not letting your phone sleep. Free app betterbatterystats can help you identify any rogue apps

Thanks for that suggestion! I shall install betterbatterystats and cpu spy and see what happens to my phone as i let it set over night. I've seen it drop by almost 20% in battery life overnight for some reason (~8hours)...which I find to be unacceptable.
EDIT: Please read this entire thread, there's some good info. Every phone and every situation is different, however it turns out my battery drain was the result of my phone not hitting "Deep Sleep". The culprit was my SD card, if you're experiencing battery drain after upgrading to ICS try removing your SD card and restarting your phone, use the app CPU SPY to verify your phone is now hitting "Deep Sleep". Again please read on, amidst some trolls there is more detailed information.
SIDENOTE: This being my first thread I have to say on the whole I really like this community!
I never thought I'd be that guy saying don't upgrade to ICS, because the OS is so slick and fun. However the glitch with the battery drain nullifies it's value. My brand new phone, less than two months old will die before the end of the day without me making a single phone call. I'm talking maybe an 1 to 1.5 hours of use texting, checking mail, surfing, and my battery now runs dead before I even get home from work. If you go into Settings > Battery it will show you the break down of what's using what. At the top should be your display, it takes a lot of power for to run the ultra bright display and this is what I saw before the ICS update. After the update these are the numbers:
Android OS: 58%
Screen: 18%
Cell Standby: 10%
Phone Idle: 7%
Android System: 2%
The OS is taking 58% of the battery?!? This is crazy!The buzz going around the net is if you do a factory reset it will fix the issue, well it does, but only for a very short time.
I went through the pain and formatted my SD card, then did a factory reset on my phone lost everything, well I backed it up, but still was a long process. After all that I loaded up my apps, and everything looked great. If you I went into the battery break down Screen was back at the top and the Android OS was several rungs below. I was SO happy! It was worth it after all.... THEN
Imagine my chagrin I woke up this morning to a full charge. Didn't make one phone call, just checked a couple emails, and being only a HOUR into my day my battery is at 76%!! I look back at the battery break down, and there's Android OS sitting at the top, draining double the battery juice as the screen display. I mean this almost makes ICS useless, what good is this great cell phone if you have to be tethered to a power cord. WTF!! Point being, don't bother resetting your phone, it DOES NOT permanently help. If you haven't upgraded to ICS don't, we're all just screwed until they come out with a fix, and you see how long it took them just to get ICS.
I don't know what happened between last night and today, but my hope is some dev person will read this and it will help them pinpoint the issue.

Nope, the only thing I backed up was pics, music, and video, and I combed through those folders to make sure there were no sys files.
It sounds more like your battery is going bad. You can go to Sprint store and they will test your battery for you.
You might also want to get a battery monitoring program and see what is using the battery up.

its not a ics glitch its your phone lol.. ive never had this issue.. plus with the source kernels coming out and with roms/tweaks already out youcan increase battery life yourself.. because your battey cant keep a charge you bash ics? go back to gingerbread then lol. i can use my phone for two hours and leave it off charger over night and still have at least 50% charge

Having a bad battery would not make Android OS use the majority of his power though. I have had this problem myself in the past and never did figure out exactly what stopped it. Running Blue Kuban now and my battery life, though never great, is reasonable. FYI, I also run Juice Defender which makes a substantial difference for me.
Running pretty much stock ICS FF18, just have agat safe recovery/kernal installed. Yesterday I left Wimax on all day and when I went to charge it last night it had about 28% left. I made several phone calls, many texts/whatsapp messages, reading emails and using twiitter/fb a couple of times.
The battery life on this is not the greatest, for example, I forgot to turn off wifi when I left my house the other day, well my battery dropped about 30% in just a few hours. I now find that just leaving Wimax on all day is actually better and pretty much on par with just having 3G on, I prefer wifi at home but if I forget to turn it off it kills my battery.
I was so used to Blazers 4.1 battery life, the battery lasted forever and I could leave wifi, bluetooth etc on all day. Just hoping for the ROMs to start incorporating the recently released source so that we can get better battery life on these great ROMS.
This is all known information. That's why you use custom roms that have much better battery life.

I had same issue here with custom rom FF18 touched by SGS3. Went back to EL29, FF18 is glitchy and slower anyway.
Confirmed, factory reset battery drain exists.
OP, why don't you put up a screenshot of your battery graph? The expanded one, not the one that lists the percentages.
There are a number of reasons why this could be happening. One of my biggest drainers on CM9 was Google login service, turned out the "keep this device backed up with Google" in the backup and reset settings was completely preventing my phone from going to sleep. This is but one example.

I'm a super n00b, if you or someone could link me to the best ICS ROM the cool kids are using I can figure out how to install it.
-----
However bottom line, before ICS upgrade my battery life was great and my Android OS was not 50% of my battery power. I'm not rooted or have any custom anything, after the ICS upgrade my battery drains rapidly. I'm willing to do what it takes to get it fixed, however I do fully put the blame on ICS, I'm using stock everything, the battery is good, something in that update is screwing my battery.
All I was trying to do was give developers, a little insight that the factory reset temporarily fixed the issue, for 3-4 hours before bed I monitored it and everything was good. So hopefully this will help turn the light bulb on in someone else's head.

ICS works really well for some, but for others it renders the phone completely useless. I'm one that it won't work for as well. The battery life is **** and 4g connectivity is non existent. As a result, I'm back to EL29/GB until a patch is made.
I spent 4 days after teh OTA was released trying to find fixes, trying to make it work, using different kernals and modems, but had no success. I posted about it many times and more or less was told that I was doing it wrong.
On that not, good luck mate. Here's to hoping for a patch from samsung soon. :good:

I have a thread stickied in general called "welcome to he et4g" that might be a good place for you to start, from there you'll figure out what you need to search for to learn more... there is no best rom its a matter of opinion, so read the dev threads and see what looks good to you... bottom line without seeing more information from you I would guess you have something running in the background preventing deep sleep, as mentioned earlier... also are you leaving wifi, Bluetooth, etc on? That'll kill your battery quick... do you live in an area with poor sprint signal? Constantly searching for service will also drain you battery. What do you have to set up to sync? And how often? There are easy ways to prolong battery life on ff18 and the vast majority of people complaining about battery life have not taken positive steps to learn more and resolve their own issues... it can be done, good luck

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.

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)

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:

I'm always sensitive to my device, every time when I feel that battery drains faster than before, I will always find out what was the problem that caused battery drains...
It's kinna pain in the ass to see battery drops faster than the first time I used the device.
So far, those suggestions that I've provided are my "BEST" solutions. (My opinion)
I will also continue to monitor my device after flashed the new MA6 French firmware...
I will see how is the results and share my experiences to you all (For those who would like to listen... If I am wrong, please don't blame me and I'm sorry)
:good:

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:

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?

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

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)
SORRY FOR MY BAD ENGLISH AND I HOPE YOU SATISFY MY REPLY...

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.

I have been stressing myself out about this for over a week, trying different things, buying new batteries trying new chargers, changing roms.
Turning so many things off basically making my phone into a dumbphone to try to figure out why my battery life is so bad. Could it be I just have a bad phone and need a new one??
I had a Galaxy S3 gave it to my GF, never turned any sync services off and I am able to get 20+ hours with that phone, this phone is HORRIBLE.
I was stock getting about 5 hours before dead battery (phone would get real warm- battery stats showing 33C+).
So I rooted and took it back to an LJC rom (4.1.1). Tried different modems, kernals, files tweaks with root explorer.
I bought BBS, a battery calibrator from the market and still cant see any problems that would do this?
last picture......
Should I just take it into Sprint and get a replacement???

I am running Macintosh 3.0 and I have power saver turned on, and I run DS Battery saver all day long. I am getting 2.5 days solid with moderate use. I am pretty sure DS Battery Saver is what is saving my battery. Let me know if you want to try the app. I have the .apk saved on my sdcard.

Also try uninstalling and reinstalling facebook. My girlfriend's phone (GS3, not a note) went from 8 hours to probably 14 hours just by using the mobile web version of facebook instead of the the app. Facebook is atrocious at making apps.
But it really does sound like you got a lemon here, I'd get a replacement from Sprint. I don't think I could kill my battery in under 10 hours unless I was playing a game non-stop. My phone is completely stock.
I will uninstall Facebook, and test it out. Thanks!

OP. Your problem is not your ROM or anything else. Jeeze people.
Those partial wakelocks are PURELY from Google Now and the wifi/network based location. Either turn off Google Now, or turn off network-based-locating and those partial wakelocks will disappear....I'd also wager you have Sprint Connection Optimizer still running causing your phone to hangup trying to find a network conenction.
My battery took a good hite when I updated to 4.1.2 used to get 20+ hrs with 7+ screen time now I get about 14-15 with 4-5 hrs screen time

Based on your first pictures, your status bar, and the amount of awake time your phone is showing I'm guessing a couple of things. Do you have a phone signal where you spend most of your day? If my awake bar was solid like yours I wouldn't have a battery after 7 hours either. I would backup everything and do a full wipe / clean install and run the phone a day or so.

What of the borderline useless bells and whistles do you have enabled? I.e. face recognition/unlock, auto-brightness, SPen battery saver etc? Things like battery savers unsurprisingly don't help so i'd nix it as it is only wasting battery.

Meh. On this device I always aim for getting 10%/ battery usage per hour of screen-on-time on TouchWiz ROMs, and a fraction of a percent per hour in screen-off....something is burning battery here, and it is probably a system setting.

No face recognition/unlock, auto brightness is enabled, but with that little screen time does it really matter? No SPen battery savor. Thanks for the suggestions.

The thing is, I have a Galaxy S3... The Note II is setup no different then that, settings or otherwise. I am trying all of these suggestions, but why did I not have to turn any of these off on my S3?? Same service area obviously. I took the Galaxy S3 off the charger last night at 100%. Put a new battery in the Note II so it was at 100%. Let them both sit on the counter for 1 hour. S3 had 98%, Note II was at 87%... No calls no texting, no screen time. It is so fustrating! I have had my fair share of battery tweaking with previous phones (HTC EVO, HTC hero). It seems something isn't right. I had problems with stock rom, that is why I rooted so quick, to try a different ROM.
If the wipe does not work I will try to get Sprint to get me a replacement, was hoping the get this figured out before I fly to Florida for a week. Good thing I have extra batteries.

Bought Ds Battery savor. Charged phone to 100% put it in airplane mode went to bed at 11pm (phone at 100%), woke up at 7am and it was at 8% Fail! 0 screen time, 0 talking, zero everything and lost charge in a little over 8 hours! Going to use it in florida the next week, with my extra batteries and most likely going to return when i get back
Thanks All for your suggestions!
