Im sure we had posts like this before. But Im stuck and need help. I was on cm7 nightly 87 with oc kernel. 5/23 and all was well. The this Saturday after playing pvz before going to sleep I put my nook to sleep with approximately 40-50% on battery and in the AM it was dead. I tought maybe I was wrong with the battery charged it to 100% flashed to 93 updated the kernel to 5-23 and played around with nook a bit, battery recolabration app, screen reco etc... Went to sleep approximately 70-80% woke up in the AM 44% just now typing this on nook went from 44 to 39% battery use shows android os 49%
I do play with new apps and maybe installed something bad but I can't figure it out. Please help
that is called PMD premature battery death.. theres a thread about it in nook android dev forum and is an issue with the current cm7

Thanks have to research that. Why would this just start ? It was working very good before. Thank you very much for the very fast response.
The latest nightlies (91, 93, and 94A) have an experimental fix that seems to improve things.

Yes I installed the latest nightly and left the nook over night. I left it at approximately 11pm with around 75%-80% this morning at 7am it drop down to 57%.
What I dont understand is that I didnt have this issue for a about a week that I had the nook and had the 87 nightly on it. The battery was amazing. It just kind of happen. I will start posting in the PMD thread this is very strange. Just seems that around 30% of battery disappears if nook is a sleep for a while.
No Drain - No Pain
I'm running version 88 and have virtually no drain whatsoever. I use an app killer and shut off the wifi before shutting down each night but can have less than 1-2% drop by morning. I can go a week without recharging.
Log battery stats
CurrentWidget, available in the market, is capable to log battery voltage, percent, current, and running applications list, to a file. It is also a home screen widget. Select widget type=clear text. Edit widget and change presentation to 2 column style. With these two changes all information is shown clearly. Touch displayed data value on home screen widget to cycle display between current, percentage, or voltage. Its useful and well done.

Wow thanks have to try this. Also will try shutting off the wifi before sleep. The issues is that I had no problems prior to Saturday, it was working flawless I would get no battery drain I would go to sleep with WiFi on no killing apps and get approximately same battery as when I went to sleep it was great. I dont get what happened.
Also like I said before in about tablet > battery use the "Android OS" now shows 41% when the battery gets drained. So some thing happens. I guess I can wipe /system /data and start over. I flashed the latest nightly this morning while the battery was on 55% (this is drain over night, as before sleep it was 77%). Lets see how it goes. And I was so happy how this thing performed !!!!!!
It was when you flash from n87 to n93 is the reason your battery is showing such different charges. the reason your are battery is draining so fast is because your nook is not deep sleeping. you can check to see if your cpu is deep sleeping or not with a free app named "cpu spy" Im also suffering from SOD and no DS.
There are 3 battery issues right now with the nook.
1) PBD, you can read about it here:

I was still on 87 when the issue first occurred. Now I understand everything you posted and will be more then happy to fill it out and etc.. what I dont understand is how come this worked before with out any issues, with no modifications

Also I never got Sleep of Death, I just got home and I`m about down to 21% from this morning 57% which is approximately 10 hours, there was some use today. I installed the cpuspy and current widget.
Cpu spy does show deep sleep 20%. I just put it on the charger and will take it of today. I did put all levers down in Nook Tweaks.
Lets see what happens. Now will report in the AM.
Today I had battery issues as well.
When I look at the battery usage, it showed
Phone Idle used 29%
Display 28%
Cell Standby 22%
Data enabled was turned on in Mobile network Settings. I turned that off and will check again. What would be using that if there is no hardware?
I had those turned off as soon as I installed CM7 few weeks ago
I've heard it explained thusly:
Phone idle = device idle
Cell standby = radio standby
Disabling those functions does nothing to increase battery life, as reported by kernel devs, though many users report otherwise anecdotally.

Had you by any chance just rebooted the NC before looking at those stats? The only time I've seen stats that high for those processes is right after powering the NC on. At that point, you're only seeing usage statistics for the last thirty seconds, and like any statistic, the smaller the sample size, the less meaningful the data.
I was in a reboot cycle where the unit would not power on without being on the charger.
I just checked again after installing build 95 and at the top of the screen it says 15 hours 50 minutes on battery. The percentages are still the same as before.
Ok here is my report from this AM. Took it of the charger last night at around 10:45pm with 100%, rebooted in to recovery to clear battery stats, rebooted to CM7 went to wireless enabled the wifi, deleted 1 wifi network (more on that below), made sure it was connected to my home network. Pretty much it. Battery showed 99%. Woke up just now 7am, battery shows 98%. Great.
So here are my thoughts and I think I have to experiment a bit more before conclusions.
1. Nook Tweaks with DAC boost could be causing an issue, maybe a better idea to do on demand rather then set on boot (still have to experiment.)
2. (this is most likely one) I live in Long Island and we have free wifi from Optimum (cablevision) from my house there is a week signal for that SSID and some times Nook did get on it instead of the home SSID. I suspect that it was jumping between SSID and thus draining the battery, this is why I deleted that network before going to sleep.
3. N95 fixed everything that was wrong.
4. I changed wifi to sleep after screen is off, that could of helped as well.
More testing will be done in coming days.
I do have a question regarding the OC kernel and governance. I do remember having 4 options, but now I just have to 2, performance and conservative. First question which one to use ? Second question where are the 4 governance ? Why arent they showing up ?
Thank you guys.
Dalingrin found that the smart-ass and interactive governor were causing issues (don't recall what, exactly) and pulled them out. Conservative is recommended.

Got it. Thanks.
I'm on n98 with the 5/23 OC kernel (I believe). I always make sure minimal apps are running, I only have the wifi/sound/bluetooth toggle widgets. Screen brightness kept to minimum needed for visibility.
I charged up to 100% at about 6pm. Put it right to sleep (no wifi or anything running) and within 10 minutes it was down to 98%. I read for about 30 minutes using Aldiko before I went to sleep and for 20 minutes on the train to work. I pulled out the Nook on my lunch break to read some more and it was down to 59%, and that is just sleeping and reading (on low brightness) for about an hour.
I always have ample opportunity to charge wherever I am, but I'm just paranoid about battery life not lasting at all even when I'm barely using the thing.
I was set to OC @ 1100Mhz on Conservative but I knocked it down to 800. I don't know if that makes a difference.
Should I go back to an older version? Go to stock ROM? I'm really only going to use the Nook to read and watch Netflix on the train, or browse some websites on my lunch break. Nothing too heavy.

I dont know what the deal with it. I downloaded juice defender and nothing has changed.
I unplugged it from charge today at 6.20am as of now (10.20am) I have %79 battery left. 5 mins (if that) web surfing on 3g, 10 txts and 3mins of voice...
This is just ridiculous. If I was a moderate user I will have no juice by 2pm
I dont get it??
I have cyanogen mod 5.0.7.1 with oc'ed kernel. Screen brightness is about %20-%25 and it times out in 1 min. It syncs every 2 hours.
Try Enom's official ROM. I get nearly twice the battery life on that than on cyanogen.

No need to be smart about it. My buddy has the same rom and with moderate usage he gets 24 hrs of battery life. And also, It down clocks to 245mhz when it is not in use.
Well, you've answered yourself - if the ROM is the same, you have 3 options: faulty battery, faulty HW, or different apps installed and one of them draining your battery.
You can test the battery by switching batteries with your buddy, and you can check the apps by doing Nandroid backup, wiping everything and monitoring the phone battery drain, possibly even comparing logs of switched off devices (yours and your buddy's). In case you'll keep seeing significant difference - there will be no other way but to assume your HW is faulty. In case your battery is ok and wiping helps - install apps one by one and monitor, to find the rogue one.

24 hours.... I cannot make it through an 8 hour work day.... sure I use the phone, but that is the point of it... I went to bed at 100% woke up at 94%... pretty big drop for sleep mode.... this screen and hardware, you will not get great battery life without tweaks, IMO.... (or just do not use it)
everytime i use cyanogen 507 i ALWAYS get poor battery life. i switch back to stock ROM and its better. i really dont know why that would be like that though...

psh i took a nap one night (maybe a 3 or 4 hour nap), left my battery at i would guess 20-30 percent and when i woke up, i wanted to check my tweets so i hit the home button, come to find out its dead O_O
I see 2.5-3.5%/hr here.. No Facebook or Twitter syncing, but Google cal/contat sync, K9 IMAP Push email, weather updating, some other misc stuff...
CLEARLY something is wrong... Have you guys run System Panel or something to monitor the processes running to make sure something isn't driving the CPU all the time or something?
Do your phones get warm? Mine stays ice cold if it's outside of my pocket at home or at my desk at work, 73ish degrees F/23 C.
What about when you first load a ROM and the setup wizard has a checkmark next to Data collection by Google? Could that be it?
You should check the "Other Usage" section of the Battery History (in Spare Parts). See if your phone is sleeping at all. If the awake time is 100%, then something is keeping it awake, so check the "Partial wake usage" to see which app is doing that.
going from 100% to 94% while you sleep overnight seems pretty normal to me. certainly doesnt seem "bad".
definitely use system panel to see what's using your CPU. in monitoring, history, plot, top apps.

well some of this is going to be common sense, but today I turned off 3g (use 2 g networks only), wifi and the gps, I turned off live wall paper and I turned my brightness from auto to 40% (which, you cannot even tell the difference... the phone is still well lit). I turned on wifi or 3g when I wanted to check something.... and then turned it off.... today was not a super busy day on the phone.. but at the end of the work day... I had 60% of my battery left.... it is usually around 10-15%... I got the ideas from this site

hope it helps. Don't really need all the blind when not using the phone!
Ok, so ever since I upgraded to CM6 (which I LOVE) I've had serious battery issues and I've tried to fix it by installing Pershoot's kernel and I have SetCPU to underclock in depending on what battery life it's at. Also, I've wiped my battery stats and I've calibrated my battery already.
Today my battery was at 64% after only 3hr and 26min. I don't have GPS on, auto backlight is on, 3g/2g and sync are on. If it makes any difference I have the Korean radio installed (which btw improved my reception a lot! ). After about 9hrs and half, my nexus one died. As per usage, I wouldn't say it's much at all because I'm in class most of the time and I've only talked on the phone for about 1 min, browsed a few websites, and sent only a few texts.
I keep reading on the forums about how people are getting 1-2% lower per hour while on standby but the % I reported earlier, my battery's draining at over 9%/hr!
I really just want to be one of those people that can say that "I still have 50% left after 12 hours!" lol
So, is there anything else I can to increase battery life? Is my battery just crap? Any recommended setCPU profiles?
If you're one of the users that get really good battery life from your Nexus One, please tell me what you did to get it that high! Thanks!
Don't use setCPU to manage battery life, only to overclock. It overrides the kernel's settings. Sounds like you need to wipe and flash the rom again. Then gradually add applications you want, something is sucking battery life.
Last, buy a new battery.
CM6 has less than stellar battery life. If you check the "help with my battery life" type threads, you will see most of the OP's have CM6 as their ROM. Try another ROM, you will get better results.

Quoted for lies
I'm using CM6 and I get between 22-32 hours on a single charge. I just use the kernel that comes with it and i almost always have sync on. No GPS or bluetooth though.
Are you using a battery you purchased on ebay? Or are you using the stock battery? ebay batteries last me about 9-12 hours and die. The stock battery is amazing
Exactly the same situation as you:
CM6.
N1.
Student.
Experiences massive drainage in short amounts of time with low usage.
Tried everything.
I'll now be trying Enomther, because yes I have heard CM6 users get worse battery life.
Just a viewpoint on what I'm facing. For the past week I've gone to bed with 100% battery and woken up ~7 hours later on 75%. I've tried WCDMA and GSM auto settings and neither male a difference.

Thanks, I'm glad I'm not the only one with this problem. I thought I was being an idiot by doing something wrong...
I've calibrated my battery several times already while trying to fix this issue. Could that have killed my battery life?
1) Discharging the battery below 10-15% is bad for the battery, doing it many time will destroy the battery, making it last just about nothing.
2) Check CPU usage - download System Monitor or some other app like that, and check the running frequency of the phone. When you just run the program and don't touch the phone, it should float around 300 MHz. If you have it locked on 998MHz - you have an app that got your CPU stuck in a loop.
3) Download some app that stores battery stats, and check your discharge current and battery capacity - that way you'll know if it's your battery dead or your apps drawing the juice.
Sorry, double post.

crap, all the guides that i've read regarding calibration told me to discharge it completely.
My CPU usage seemed normal. It was stable at around 245 and would jump up to 998 from time to time that doesn't last for more than half a second though.
My battery seems to be in good condition as it's labeled as "healthy" by my battery apps and the voltage seemed normal....

Do a nandroid back-up of CM6, and then try out the above ROM. You can always go right back to CM at any time.
For calibration, complete discharge is necessary. Doing it once is not too harmful. As long as the battery is reported "healthy" - you're ok.
There are apps that will show you the approximate capacity of your battery in numbers. Try to find one like that.
Please check discharge current and voltage over time. It doesn't make sense that a phone on 245 MHz in sleep mode will draw the current required to discharge 10%/hour.

Awesome, if you find a fix let me know please.
I haven't been able to do any of the suggestions yet but (when it comes to flashing) but I do have an update that might shine more light on this issue.
Today in class I noticed that my N1 was warm when it was in my pocket but nothing was running and gps and bluetooth was off. I checked the temp of my battery it was at 36.1C while it's usually at 30-31C when I'm not doing anything.
Also, I checked spare parts this morning and found that, while I was asleep, my N1 was not asleep for half that time but my screen on for only 4% of that time (probably from my messing with it before and a little bit after sleep).
I've checked to see if anything is running in the background that might lead to this but so far none of my apps should drain my battery that much while I was asleep.
Is this normal? Shouldn't my phone be mostly in sleep mode when I'm asleep since I'm not doing anything to it? As for the battery heating up, do y'all think it's a faulty battery or the fault of the OS?
Thanks again for all of y'all's helpful replies!

About battery heating...
I checked and mine is at 75-78F while in class. My n1 is also in a case, so for it to be that low is good. Just thought to throw that in as a comparison.
Also i've switched ROMs to help with battery, no luck there. Still experience 7-8% drop per hour.
I've been keeping my phone off now at school, which has helped, though I still lose nearly 15% while it's off.
Sent from my seXus One using XDA App. While I gripe about battery stats.

Hi folks.
Sorry if this is a redundant question or thread, I have used the search feature and am not getting the results I want. Furthermore I have a 2 year old and 9 month old hanging on my legs here and just need an answer so again apologies if this is redundant.
I have had my Captivate for about 5 days now. I rooted it and installed Serendipity 5.3 ROM. Today I noticed my battery went from 100% to 5% in 4 hours. Is this normal?
I got home and updated Serendipity to 5.4 and then 5.5 but not sure if that will fix the battery issue. The day before I ran the battery all day 10 hours and I was at 35% which to me was normal as my iPhone 4 had the same performance. But 100-5% in 4 hours seems a bit strange.
Any help would be appreciated sorry for the long post I need to get back to my kids.
Thanks!
4 hours for almost 100% battery usage is not normal.
check your wifi setting, gps setting first.
Sounds to me like your battery needs a calibration. It's generally a good idea to re-calibrate your battery after flashing. I generally get 20hrs on my Captivate with Serendipity 5.2 with average usage.

Thanks to both replies
Now that one kid is asleep and the other on her way....what is the optimal wi-fi setting for best battery life and the same for gps?
Also, I looked at that thread and I am in process of trying it out integrasaurus.
This is my first time with an Android phone, I came from an iPhone 4 jailbroken so I am an Android virgin and 5 days old.
I also want to say I am sorry about starting a thread if this topic was hit on already. I have been around forums a long time and I know how frustrating it is when noobs do these things so I thought I'd offer my sincerest apologies for doing what I would get mad at too.
usually after you flash a new rom, the gps is set to on. turn it off if you are not using it;
go to settings->wireless and network->wi-fi settings, then click menu to bring up the advanced->in the wi-fi sleep policy->make sure select "when screen turns off";
go to settings->applications->samsung apps->make sure it is "off"

Hmmm
I dont see this?

I got the wi-fi taken care of though thanks for that.
It was strange today though, I plugged the phone in to wall ac and it took forever (5hours) to charge from 5% to 40% and then drained in less than an hour back to 5%.
Its charging now and has been on my usb port for 2 hours and its up to 72% from 4%.
That was also a confusing mystery.
Hey guys, just want to say thanks again. I'm still working on calibrating batt but I after reading some more in the forums (kids finally both in bed and OUT) I discovered that I had 2 task killers installed and that these apps are battery killers (at least in some opinions).
I uninstalled them and charging seems to be moving faster than before. I will let you know how things go.
Thanks again!
I am running Serendipity 5.5 and my battery typically lasts between 26-30 hours with normal use. I don't use any task killers, but if you have your task killers set to be too aggressive I'm sure that would drain the battery pretty fast. I'd suggest just ditching them completely though, as I get over a day's battery without trying to manage all of that.
Also, check if ur gallery has the sensor bug. U can find this out under battery usage using the SPARE PARTS app.

yup, I deleted them already. I believe that was the cause of the sudden change in life, as I didnt have many problems before them.
After my battery cal I have been running the phone on and off normal use for over an hour. Battery is now at 95%, started at 100%.
I see improvements already, but will hold off saying its fixed completely until I can give it a day or two of testing.

sometimes the thumnails get corrupt which eats battery while trying to load and need to be "refreshed" a simple way to do this is in the app SGS TOOLS run the script "clean_thumb_db.txt" this should fix gallery issues.
Thanks for this info. This will be something I will keep an eye on for sure. Phone is still above 90% after over 2 hours. Hoping the calibration and deletion of task killers did the trick.
Sent from my SAMSUNG-SGH-I897 using XDA App
Charge battery 100% then some... Power off phone and let charge longer... Boot into Clockwork and reset battery stats.... Run the phone a few charges and you should be gold.... Under normal/light use I can get 1.5 days out of my battery...
Also check your wireless settings. Try setting them to turn off wireless when the screen is off. That was a huge battery drain for me.
Thanks to all here for the help and thoughts.
So last night I
1. Got rid of task killers
2. Updated Serendipity from 5.3 to 5.5
3. Adjusted wireless settings
4. Calibrated battery
I finished all this at 8:15pm CST and the phone has been unplugged since then, with moderate use between 8:15 and 10:15pm. It is now 7am CST and the phone is at 63% power which is a huge improvement from yesterday.
I am convinced it was the task killers that had the most drain on the battery.
I will give it one or two more days and see how performance is then and let you know.
You guys rock!
Back on Serendipity 4.3, while OC/UVing I could get about 25-28 hours with normal use, texting throughout the day, occasional calls.
Now that I'm on 5.5, I am getting about 28-32 hours, still OC/UVing.
Also, I use advanced task manager, and it doesn't kill my battery at all. Any more than other apps at least.
Glad everything is working out for you iDroidd!
..Now back to flashing lol.

so I went 22 hours on one charge, now that's the initial charge of calibration. It's plugged in now we will see how it fares going forward.
Hey guys,
I'm running the latest release from nadlabak, 04.10 one.
I experienced battery issues on some previous releases as well, however i don't know if it's this release or what, but the battery usage is draining very fast!
I am not really running anything, I have liveprofile auto memory manager, and handset sms. liveprofile doesnt even really run, i barely use it so it should be either in the background or not running.
i looked at the battery usage stats, it shows email is using about 40% of the battery draining.
my phone is VERY warm, feels like the cpu churning through something... i can run at 52vsel with 1000mhz vrate. fine and still my battery is about 40% after 2 hours.
I reset to factory clock speeds and it drains the same if not faster!
not sure what's going on but its driving me nuts, google maps also shows to be running in the background, however i never turn it on, i reboot my phone, leave it as is and it shows maps is using 10% battery usage roughly when i havent even initiated it to be running(unless it always has a service in the background?)
i had releases from march that ran better, about 8 hours of battery life. and i believe even a april release was working fine. but now this latest release especially seems to suck up the battery, i dont know if its the releases or if something else has changed...but its very annoying holding a very WARM phone and having the battery get sucked up in 3 hours.
Looking at spare parts, does it sleep at all?
40% usage from email is high so something is wrong there but I doubt it's CM7.
Also, what AMM settings are you using?
Hi there, I'm running the following:
vmheap 40mb
amm: 6, 13, 24, 40, 51, 63.
any suggestions?
where do i find out if it sleeps, im in spare parts.
In Spare Parts, the first item is Battery History.
Go there and it will show how long your battery has been running (%) since unplugged.
If you select the top drop down list, select Partial Wake Usage to see which apps might be keeping the phone awake.
Where did you get those AMM numbers from?
I'd suggest my Balanced 3 (6-8-26-28-30-32) for a nice mix of free memory without being overly aggressive on the background apps.
If you use any of my scripts, disable AMM from having superuser permissions.
I had gotten the stats from another popular thread on this forum.
ill try your stats as well.
vmheap still 40?
also i still notice email is the one that has a huge bar graph usage on the partial usage stat page. not sure why email is being kept awake..
should i factory reset?
have you wiped cache/dalvik? If not do that.
Sent from my Milestone
I had wiped the caches multiple times, tried a lot of things, everything accept a factory reset.
I did a factory reset for the hell of it, set the amm settings as requested vmheap to 40.
everything seems to be running smooth and fine at 1000mhz 54vsel
and the battery usage is at 90% while being unplugged for 7 hours, will monitor to see if the usage drops substantially later on in the night but so far i think things may be fixed.
Battery usage is nearly constant.
That's not good at all.
Something is keeping it away.
What does spare parts show now for partial wake apps?
The partial usage is like 5% now vs what was like 50%. and email isnt even probably 2%. handcent sms is taking up the 5% roughly.
its at 80% after being on battery for 8 hours 26 mins. and i have probably used it for about 30-45 mins worth of on screen time, rest idle.
Oh wait, I think I misunderstood.
You meant that you had 90% left and only 10% used up, right?
If that's the case, that's pretty amazing.
I have expirienced that if I haven't done full wipe(factory reset) my battery is drainin like a crazy. That's happing in all roms I have used. So my opinion is to apply any update or now rom on clean Milestone
how to delete apps in android
i have recently started using android on htc hd2.. i am bit annoyed with the fact that i could not unistall a few apps which i am never going to use. eg liveprofile..and it keeps starting automatically
so could anyone tell me how to remove such apps?
I didn't use the note much, but it needs to charge each day. This is bad than tablet. Any software to save battery? I tried 'air plane mode' sofeware, but it also turns off phone after sleep.

What apps and widgets are you running? Have you gone through 2 or 3 full discharge/recharge cycles? There are apps out there that can detect if any app is consuming your battery but you will have to search the forums as I don't know of any first hand.
Also, which ROM are you using? When I was using Rocket Rom v22 with AbyssKernel 4.1, my Note would last more than a day on the same charge even with moderate use. Give that a try as it also really boosts performance.
I'm currently on Team Rocket Rom (ICS based) v5 but have not used it extensively to comment on battery yet. So far with 3 activesync email accounts (all push), some widgets running (weather, clock, etc.) and the Note sitting idle consume about 2-3% battery per hour. Will monitor this.
most smartphones ned to be charged every day, what battery life are you expecting to get ?
battery depends on the usage and applications you installed on the phone.
have you tried rooting already? usually custom roms have the best alternatives of extending your phone's battery and giving it an optimal performance.
Try to stop some bloatwares that your phone's loading up everytime it starts up(from rebooting)

I am using la2 rom. Here i attached an picture.
Geez... i personally feel that one day charge is reasonable especially with the juice required to drive the big display.
Anyway, Juice Defender premium is one app that has helped me, and may help you too.
Since you got Activesync, with the premium version of JD, you can customize app to be excluded from 'power saving', so that the inbox is up to date.
+1 for juicedefender.
Other tips that may not be obvious to first-time smartphone owners are:
1. Set your screen brightness to auto. You don't need the brightness cranked right up all the time.
2. Disable bluetooth and GPS if you're not using them. Juicedefender will do a pretty good job of managing your other radios.
3. If you've got email syncing set up on your phone, set it to check as rarely as you can put up with. Push email uses a LOT of battery life, and even a scheduled check can blaze through your battery if it's happening often enough.
4. If you've put on a custom ROM your phone may be reporting inaccurate battery stats. Give it a full charge, boot into clockwork recovery and wipe your battery stats. You'll find a few days after that your phone will start reporting more accurately.
Good luck, and if any of this was unclear feel free to ask further questions.

Try a later ROM to see if the same issue exists. I think you should instal rocket rom v22 - you'll be happy with performance and battery life based on your usage.
try to calibrate your battery as well... there are many apps out there that offers better battery calibration or you can do a manual calibration as well.
Give it some time and upgrade your ROM
I am getting great battery life. It runs for full day (24 hrs) with 30% of battery usage. though in a day i dont use it much, just 5 to 10 calls of around half an hour to 40 minutes.. data and gps always on.. screen brightness on auto...
My note running the OEM battery last me about 6 hrs.
Averages about 45mins talk time/day
About 50 SMS/day
Screen brightness set to 100
Checks email every 5 mins
Using a live wallpaper
Refreshes the daily weather using Accuweather every hr
Bluetooth always turned on
Battery Widget
Fancy Widget
ESPN scoreboard ticker widget refreshes
Twitter running all day
Facebook Widget syncing all day
and more...

^ This. Or better yet, just always set your brightness to the lowest brightness setting, 50% afaik. And use black/dark wallpapers and always turn on night mode (if applicable, especially when using your browser)
If in case you need to adjust the brightness, you don't have to go through the jungle of settings, just click notification bar and slide horizontally to change to your preferred brightness.
Jd is hit n miss will actually helping out. If your phone sleeps a lot jd is nice at keeping cell or wifi off if your like me and on it every 10 minutes then toggling data and other things can consume more juice. .... I have tried with and without on my tablets and phones and see no big difference depending on use.
Sent from my Ice Creamy Galaxy NOTE
I was pretty happy with my battery until two days ago. I use my note very little, for e-mail checking (which I pull manually) a few times a day, and to make two or three phone calls per day. I also text my kids occasionally. GPS and Bluetooth are off most of the time. Battery used to last me about two and a half days under these conditions, which seemed reasonable to me. All of a sudden, two days ago, I charged my battery, and after a full charge it drained 60% overnight. Thought that it was a fluke, so rebooted my phone, fully charged again, and the same thing (over half of the juice gone overnight) happened again. Battery stats tell me that Android OS were 100% responsible for overnight drainage. Any clues? I am on stock ROM, by the way.
Thank you.

Get a good app to check what is using the battery or keeping the phone awake. This last is the most likely.
Baddass Battery Monitor is my recommendation.
Not a single phone call, only used about 10 mins. after 21 hours only 11% left. Install Jd with 'balanced' option.

Thank you. I will give that a try.
Badass, got to love that name....
Ok, I used the Badass monitor to see what's going on. Once again, no phone usage, quick overnight battery drainage. Android OS 100% responsible, and the main power sucker is the Kernel (96%). Why is this happening? And, is there a remedy? I have changed nothing that would trigger this! My Note is still within the return window, so if there is anything wrong with it, I will return it.
Thanks again.

Badass Monitor is very useful, my note was drained by Dolphin Browser, it used 38% of battery. Seems like for this browser, if I only press home key to exit, It will keep running?
I think the reason the battery drain fast is we press 'home' key to return to main menu, that will keep a lot of apps run in the background.
