I've also noticed that with the latest CM's battery life is an issue for me. Ive got KoR roms to last almost two full days but cm is dead within 20 hours.
My battery life has changed as well and I now have to keep my travel charger and car charger with me at all times or suffer with a dead phone.
i had been running rc3 with the 8-19 kernel, and my battery life was similar to stock, but the combination of latest CM and wildmonks are just killing me... i think im going to go back to rc3 with the 8-19 kernel.
Check the active processes. You can't drain the battery in 8 hours unless you have a process stuck, using 100% CPU constantly (possibly Exchange?).
good thought, but im not an exchange user... i cant seem to isolate the issue. im going to do a full wipe and try stock to see if maybe i have a bad battery.
People with battery life issues should try Enom's ROM with a wildmonks kernel. I'm 18 hours in of a full charge and I'm at 76%. That's normal use with full screen brightness, wifi and gps, quite a few background updating apps, etc.
Over 50% of power usage should be the display under even moderate usage.
With wifi, push, and poll active, the battery drop per hour with the screen off should be less than 1%.
If it's higher than that, you need to find the rogue process or get rid of an automatic task killer.

Display is most of my usage with over 50% every time. I have one app that auto updates in the background, Twitter, and thats every half hour. I do have 3g on but with wireless on most of the time. GPS, Autosync, and Auto-Brightness is on. I play one game twice a day, World War, once in the morning, once at night, but both times are usually on the charger.
Now that I think about it, Im a part of latitude but maps/latitude never consume battery according the about>battery.
Either way CM6 full charge starting at 4am, with light-moderate use, will be dead at like 5pm. I can go almost 2 days on a single charge of KoR rom. Enoms rom I have tried and lasts a full day +some...

I have the same issue and have had it since RC2. I can deal with it since I have the desktop dock at work, the car dock, and two wall chargers at home. The drain is pretty noticeable -- after about 30 minutes of the phone being off the charger and left alone with screen off, the battery charge is at 94% with "Display" using 65% of that. Wifi/BT/GPS off.
Like I said, it's not a big deal right now because I have chargers everywhere, but it's really annoying. I'm still searching for the fix, but if I can't find it, back to MCR for me.
I tried CM for 1 week and I must say the extra glitters is not worth the poor battery life., only lasted 1 day if used moderately. I just switched back to FRF91 Stock Rom today, lasts me 2days if used moderately. Longivity of the battery is another long term concern people should think about. I still miss my modded dialpad with big buttons, cool trackball colors and many more, CM is such a TEASE!
What kind of battery life are people getting with Pershoot's latest? It's undervolted, so it should do pretty well.

Tried Enom? I've seen zero difference in battery life, perhaps slightly better, since switching to it from stock Froyo on my N1.
In the battery use screen, what's draining the battery with the screen off? Let the phone drain like 10% with the screen off the entire time after unplugging.
several recent nighties and cm6.0.0 seem to have something broken.. Four hours of standby after full charge and the battery level already @ 83%.
cell standby 32%; idle 29%; display (wtf was turned off all the time) 28%.
Drains twice as fast compared to older CM roms..
The LEDs are also considered the Display by the battery meter.
Still, 17% in four hours is enormous. I guess I'll have to hold off on CM6 until they sort this out.
Dicks! 4% battery drain in one hour with almost no use, and that's after flashing pershoot's undervolted kernel. No way.
I'm going to try wildmonk's kernel now. :/
So sorry for adding to the battery life threads, but I'm pretty frustrated.
I've seen people posting screen shots with 18 hours uptime, 7 hours wake time and 50% battery on custom roms. I've seen people getting about 24 hours on a single charge.
I've had my evo 2 weeks now, and I've tried about 3 different ROMS and 4 or 5 different Kernels all of which promised LONG battery life. I'm currently running BakedSnack 1.7 with Kernel #5. My phone has been on 10 hours, 2 hours of wake time and it has only 35% left. Couple of short phone calls, 10 mins Pandora and a bit of browsing and texting here and there. I was expecting more after rooting, yet it seems almost the same as it was before I rooted.
Am I expecting too much ?
I've gone through the full discharge/recharge cycle about 4 times so far. Bad battery perhaps ?
will the phone charge get you through a day say 10 hour work day ( includes travel time )
imho your expecting to much with 10 hours in to your charge and still have 35% left is pretty damn good imho
Baked Snacks is a great rom ! its no the battery check your TWS
Depends what you are doing, some things (3d games, flash) will drain the battery faster than others.
If you are at 10 hours and 2 hours awake with 35% left, thats not too bad. You should end up around 16-17 hours with 4 hours of awake time.
If you are talking on the phone, that will drain your battery the fastest.
Make sure you completely condition your battery as well (as many posts show)

It will make it through but usually by 5pm its around 30%. I almost have to make an effort to use it sparingly though. I really like the Baked Snack Rom, its very slick probably the best I've had so far. TWS was 3% today.

Have you tried SetCPU? I have stock rooted with SetCPU (Perflock Disabler ftw) and without a signal 13-25% of the time (meaning the phone is searching for a signal), I end a 10-12 hour work day with about 45-50% left. Underclocking to 250 while the screen off has helped a lot.
This seems to be a common concern. first please remember to take everything with a grain of salt when it comes to people reporting there battery times. There are just to many factors to say ok if you use this rom and this kernel you will get 20 hours of battery life. Also many of the people reporting battery life exaggerate. sure they may ahve gotten 50 hours between charges on stock battery... but they surely didn't have moderate use ... or any real use during that no matter what they claim.
from another post it seems the majority of people in that post (with everything tweaked calibrated and set up) were getting roughly 13-18 hours of battery life out of there phone with normal use. normal being defined by actually using your phone as a phone as well as using its other capabilities. So my feeling if you are a moderate user you should expect to fall into this area as a goal. Things to help would include setCPU, making sure you turn off data when you shut off screen (or getting a program to do so for you - juicedefender) and making sure you calibrate your battery and battery stats of your phone.
it seems like you are getting close to this range however you are having to watch your use to do so. as others have said the first thing i would do is get setCPU and set up a battery saving profile. read through some of the battery threads if you havent and look for setting changes that wont impact you tremendously but will help save battery (for example if you dont use landscape mode a lot you can turn off autorotation and save some battery). If you are using froyo and are running a task killer uninstall it since it doesnt work any way. While most settings will make a small impact together they should help get you to where you can use your phone moderately through out the day with out worries.

Don't get me wrong here, the thread wasn't about me complaining, more about setting my expectations.
2 Years ago I had the first Touch Pro which would be dead by 3pm regardless of usage. At one point I had 4 batteries. I got the Touch Pro 2 a year later and it could go 2-3 days on single charge with normal usage. It was like night and day.
Granted this is a much more powerful device than either of those, but I feel like I've taken a step backwards with the battery situation.

I tried out SetCPU but the phone was slugglish for me at times and once or twice I had to reboot.
I'm probably just gonna grab an extra battery and a desktop charger so I can charge one battery while the other is in use.

Thanks alot for those tips, I'll give SetCPU another go.
I haven't tried out Juice Defender but I'll look into that as well. Turning off Data when the screen is off might be just the thing I need!
Alright, so I'm not a very heavy user on the phone but I've started getting 36 hours of use on my phone. I was blown the hell away! I usually would get a Max of up to 25 or 26 hours or so before this. Even then a full 10 hours extra is magnificent!
Here's what I've got going on:
Running MIUI 2.3.23 ROM with Bulletproof Add On pack
Using Tiamat 1.1.5 kernel
Juice Defender Plus on Advanced mode
Recaibrated my batter with Battery Callibrator app
Overclocking at 1039 MHz and underclocking at 184 mhz using SetCPU
After calibrating my battery I let the battery run out completely a couple of times and voila!
I took a screenshot of my usage statistics but I can't find the damn thing now. I guess you're just got to trust me on this. This was definitely worth sharing.
All the best!

How many hours of screen on time did you have at the end of that charge? The longest battery life i've ever had for my phone was actually 3 days and 3 hours with 5 hours of screen on time. I'm a light to moderate user and i achieved that result with CM7.2 RC1 without any tweaks.
I really like the look of MIUI but i don't find it to be as fast as it really should be. I get frustrated by the scrolling lag that is present in the settings menu and the fact that video playback is much slower in comparison to other ROMs. Web pages were also always SO much more laggy in MIUI for me than on Sense or AOSP based ROMs. That's my personal experience, i think i've just about given up on MIUI and Sense based ROMs. I haven't touched either of those for a while now.
I get 36 hours normally with the stock Sense 2.1 ROM and Unity V10 kernel. Overclocked to 1Ghz with the standard governor.
I use it quite lightly though, 10 to 20 SMS, bit of internet / Facebook and 30 mins FM radio in the morning. Also accounts sync automatically, mail picked up every hour, data always on. That was with the stock battery, with the Anker 1600 mah I get to 36 hours with about 30% to spare!
On a side note, underclocking below 245Mhz has been know to cause problems. Standby of Death (or Sleep of Death), and possibly dropped SMS etc.

I'm not sure how much screen on time I had. I'll give it a check next time I'm monitoring my performance.
Sense UI has been a pain for me from the moment I started. I tried CM 7 but it had a bug where it wouldn't vibrate when I got a message unless it was in silent mode. Since I SMS quite a bit, it was quite annoying. I tried a couple of Virtuous ROMs too but they were glacial in their speed. Couldn't stand the lag.
I find MIUI to be the perfect balance between features, UI and speed. It might be a tad laggy in some places, but on the whole, it looks great, works great and doesn't give me problems in the parts I use the most. It doesn't seem quite as laggy with me as you seem to describe it. But anyhoo, for the first time since I bought my DZ, I feel like I have a good phone that I can rely on.
Thanks for your comments, man.

Letting the battery drain to shutdown is not a good idea. Not good for long term life of Li ion batteries. Also, its unlikely, but possible that draining to shutdown will render the battery unable to take a charge. Fail safes on the device and battery are supposed to prevent this in theory, but in reality they don't always work. Several reports on this device of people that drained to shutdown, and then couldn't charge their battery.
The battery meter is not accurate enough to necessitate draining to zero. Just drain to 10 or even 20%, charge to full, repeat a couple times. No value added whatsoever to draining to shutdown.
I have easily gotten 48 hours+ with light usage on various ROMs, including ILWT and Virtuous Unity (which is Sense 3, and claimed by some to be a "battery hog"). This is with Bluetooth and WiFi always on, and no special battery calibration or battery saving apps.. So many things affect battery life. But my personal hunch is that the ROM, clocking, radio, and data reception in your area (and of course usage) have more to do with battery life than other factors. And with radio and reception being the really big drivers.
That's definitely very helpful. I've always heard that rechargeable batteries are supposed to be drained completely and charged at least periodically to extend its life. Your proposition is contrary to this belief but then, I don't know that much about the battery and those aspects of the device itself to be able to refute what you're saying. Best to be on the safe side though.
Current record for my battery is 42 hours as of today. I'm pretty thrilled. My device was giving at least 10-15 hours less before I made these customisations. So I feel it probably has helped. However, there are a lot of factors at play, as you said.
Thanks for the response!

There are various types of rechargeable batteries with very different behaviors. What you mention is known as battery conditioning, where you periodically drain to (nearly) empty and charge to full, and is recommended for older type NiCd (nickel cadmium) batteries. This is to avoid "memory effect" where the battery will remember how much was discharged in past cycles, and not deliver any more than demanded before. Kind of a "use it or lose it" principle.
Lithium (Li) ion cells (the type on most smartphones) do not suffer from memory effect. And full discharge cycles actually hurt the long term life of the battery. Charging frequently is actually the best for this type of bettery. But a couple nearly full cycles are needed to properly calibrate the battery meter on the phone.

I have had my Note for 9 days now and wonder if my battery may have an issue. Yes the phone is entering deep sleep, No I don't have any specific app that is running it dry. Screen takes most of the juice. I have it set at automatic brightness. Everything is off. It does auto sync. Signal is fantastic. I can hardly get 3/4ths of a day. I usually spend 30 minutes on the phone. 30 emails, 2 hours browsing, 30 minutes on tapatalk. This has always been my pattern and coming from a Motorola photon I always made the day easily. I'm on ISC (stock) not rooted just plain old stock. I'm thinking maybe a battery problem? What do you all think? Thanks for your help.

I've only had my note a couple days. I've gotten about 10-12 hours out of it both days. But that was with what I would call moderate to less then moderate usage. A little web browsing and facebook, probably less then 2 hours total. Maybe 20-30 texts and reading emails for maybe 30 minutes and 10-15 minutes of calls. I'm not sure what to expect, I am coming from a rooted HTC evo which I ran a lot of custom roms/kernels on, so I got great battery life with it. But I don't remember how it performed stock. The Note gets me through my work day, but not much more.
Charge the battery to full.
Let it drain completely (till it turns itself off).
Charge the battery to full once more.
I don't know the science behind it, nor does everyone benefit from doing this. (Something to do with calibration of the battery) but I do this after every major update, or new phone. I'm currently sat on 44% battery after 24hours usage (Moderate, certainly not heavy usage).
You have to remember the note will consume a large amount of battery simply because of its screen size (As you've noted its the biggest offender).
Someone with more experience/knowledge will hopefully be along shortly to give you better more informed advice but this is what I know from experience.
Normally what I have seen is I get approx near
4 hours of battery life (screen on time)

Batterylife on samsung ics (XXLPY) is terrible if you compare it to gingerbread. It is nearly cut down in half. I guess touchwizz has gotten more hungry than before or samsung has altered ics so much that the advantages are gone.

I do this method every 2 or 3 months on all my devices (iPod, phone, Laptop) so that the percentage or battery shown on the devices is more accurate. I read somewhere that since most of us charge out devices before battery dies completely, like we charge it when its 80 or 60 or even 20 instead of charging it when it completely dies, doing so makes the accuracy of the percentage very low but we can't help it but to charge it at what ever percentage for various reason thus, I always drain all my battery on devices completely than charge it full before using (minus the first full charging). Any ways if your ICS it seems to be a bug, it cannot be fixed until a new update.

Do the charge/drain cycle.
I've done this and improved the battery life immensely.
Currently my note has been on for 3d 21h 16m 1s and has 11% charge left - okay so it hasn't been used much over the weekend but that not a bad standby time.
Hey guys i got a s4 for free a few weeks ago and the battery was having issues so i brought a new battery from Samsung for $50. I guess the phone is $50 now huh, still that's a good price. Anyway i have an improvement in standby time over the old battery that seemed to drain no matter what, but i only get around 2hrs to 3hrs screen on time full brightness with a mix of auto. The phone tends to get warm when its below 40% power. Also using the phone drains it at a fast rate, but standby only 1% per 8mins or so witch is good. Im backing up with twrp and titanium backup, ive tried recalibration, and im about to do a factory reset on this (stock touchwiz)

Battery calibration apps are a placebo.
Anyway, let me tell you a little story:
2 weeks ago I watched a 2 hour movie on my phone. Started from 100% ans towards the end of the movie I was left with about 50% battery.
Screen brightness was around 60%, WiFi was enabled and the mobile reception was 4G.
All things considered I would assume I can get 4 hours SOT, since it took 2 hours to get from 100 to 50.
This is on a custom rom and battery oriented kernel settings.
Also take into account that I was watching a movie, so the CPU was idling most of the time. Doing tasks and switching from one app to another drives the CPU up.
Your screen-on time seems acceptable to me. I have to mention that my battery is one and a half years old, but I always took good care of it (I never let it discharge too much and never left it charge too much, as both of those, over time, can reduce its storage capacity).
Im using Albe95 rom with a custom kernal and the battery is draining slightly less, ive reduced my brightness to 60% and its drained from 100% to 77% in standby and extremely light use in 6hrs (about 4hrs standby drained 6% and 2 hrs of on off use every now and then drained about 17%. I guess im used to my old LG L70 D320n witch could hold up at full brightness forever. Will Cyanogenmod 13 bring much improvement for me?

I don't know. Maybe Optimized CM13 because it has a custom kernel and you can select battery or performance profiles.

I still dont get why i should have to do that with a BRAND NEW battery

You won't miraculously get 5-6 hours SOT even if the battery is new.
Maybe with lowest brightness, WiFi and mobile data off you will.
Underclocking and undevolting might help a little, but I don't see anyway of getting more than 5 hours.

There's a guide in the general section, _Bon_Bon's tweaks.., Something along those lines is the title.
It has a guide on how to increase battery life.
The guide is based on alucard kernel, though.
Alucard kernel is available for any 5.0 and 5.1 roms. But there is no public build for android 6.
Only JDCTeam roms have alucard kernel for android 6. Those roms are Optimized CM13 and AOSP 6.0 rom.

Ok so slowly things have improved but today when it was at 9% (6:30pm charged this morning) it froze up and i pulled the battery. Then it jumped down to 2% at restart! This has happened before (cant remember if it was on stock rom or the note 5 rom im using on it now) from 40% freeze, pull battery, restart, 22%! Any idea why this happens. I talked to samsung about the battery performance and they just wanted me to send the phone too as "its not just the battery" just for more money instead of honering their 3 month ****ty warranty! Stick it samsung my next phone will be lg like the rest, even though i only just brought this damn phone

The freezes might be caused by CPU undervolting, if you did any.
But the battery percentage dropping suddenly is a sign of a bad battery. It might drop 2 or 3% during the boot up, but not 20%.

Samsung say the phone is the problem. Today i got to 40% and it jumped to 30% within 20 mins. Then i pulled the battery and started the phone up, repeating this multiple times to see the battery percentage. It jumped between 24% 15% and 19% up and down each time i pulled battery and restarted (no crashing just to see what happens). Is this enough to tell Samsung ITS NOT MY PHONE.

Apparently they refuse to accept the possibility that they might have sold you a faulty battery, so they blame the phone.
I don't see how the phone might drain the battery from a hardware perspective.
It's possible from a software perspective, but since you changed roms it is unlikely to be software related.
Did you install any apps to check if the phone enters deep sleep? Or if there is anything keeping the CPU at max frequency?

Wake lock doesnt find anything strange. Even twrp battery indicator in my custom recovery experiences the same effects

Ok ive done it a few more times and it seems to possibly be a calibration issue. But ive calibrated it multiple times before

How did you calibrate it?
Battery calibration apps are a placebo. What they do is they delete the batterystats.bin file which, as stated by a Google engineer, has no relation to battery life or the battery display.
Also, that file gets deleted automatically at every reboot by android itself.
What you could do is:
First let your battery fully discharge, until the phone turns off. Then try to turn it back on. If it turns on, proceed to use it until it turns off again. Do this until the phone won't turn on again.
Now the battery is completely empty and you can plug it in to charge. Let it charge to 100% without interruptions.
Take into account that it can take up to 3 hours to fully charge.

Haha done this before to no avail. Will do again but i noticed battery life is generally better if i leave it charging for 10hours after its charged fully. Instead of taking it off when it gets to 100% but i think a long worded and very angry email is about to be sent to the Samsung repair centre

on my travels around google I've read many times that with lithium batteries you NEVER want to completely discharge or overcharge them. give it 10 minutes extra once fully charged, not more. you're damaging the poles or terminals or something I can't remember fully when at either extreme. all you achieve is a shorter lifespan for your battery.
discharge it until it turns off but never until it can't turn on again. it has a chip in the battery that needs to stay powered too.
