Loving the DNA so far but I've noticed my kernel usage has been high. I don't think It's almost never been below 30%, at one point it was at 50%. From my understanding this is not normal and is creating bad battery drain. If anyone has any suggestions or advice it would be appreciated. Maybe I should try a different kernel? Here's some screenshots from a few minutes ago.

You can try a different kernel there are two different ones in this forum: http://forum.xda-developers.com/forumdisplay.php?f=1967 . However, the kernel is (are) the piece(s) of software that basically runs everything, so having the most battery usage out of the kernel is to be expected. The kernels on the form I gave may have better battery usage for multiple reasons (optimized resource usage, bloat removed, etc.) but it will (probably) still be the biggest battery eater.

Thanks. I was kinda thinking that. It makes sense that the kernel will be higher in percentage the less the screen is used and vice versa. Just seemed like my battery drain was excessive and since the kernel usage percentage was the highest I assumed that it was the problem. I'll give a different kernel a go and see what happens. Thanks again.

Sure thing, but don't expect much more battery life. With a quad core processor, two gigabytes of RAM, a 1080p screen, and an active 4G radio this monster draws a lot of power.

It would be helpful if you elaborate your Note's set-up. Such as like what ROM is being used, brightness level, LTE/no LTE, etc...
My Note currently has no issue lasting a full work-day with LTE on the whole time. And this is with moderate usage. (No videos, and minimal music)
I'm satisfied with mine... Just keep a charger near by.

There are only a few reasons why you see your battery life as terrible.
1) You are coming from an iPhone. But now you're using a tool of a phone, not a toy, so your battery life will be lower.
2) You are coming from the Droid RAZR MAXX, which is the only android with a bigger battery.
3) You have a rogue app that you didn't use before that is draining your battery life.
4) You are using excessive amounts of LTE data, and you came from a phone without LTE.
If those apply to you, there's your answer. If they don't, you may just have a bad device or battery.
You really need to be more specific when stating something as subjective as battery life is terrible. May I suggest you post screenshots of your battery stats so that you can give some insight to why your battery life is terrible. Coming on these forums and ranting without evidence won't get you very far.

Pretty much every device is unique, even though they are produced and assembled in identical fashion. It's possible for a device to have faulty software or internal hardware from the factory that could drain battery, and it's also possible for it to be shipped with a faulty battery. It's not a common issue, but also not unheard of. If nothing in his usage of the device is out of the ordinary, then it's possible he received a faulty device or battery, and should exchange it.

Install cpu spy and make sure you are going to deep sleep. For weeks I couldn't make it through the day and once I realized that the phone wasn't sleeping I found the app that was causing it and deleted it. I get great battery now but still reboot every morning because my original charging cable was lost so my phone will not sleep until I reboot.

I would say battery life can be defined by screen on time only.
Brightness and lte makes much difference.

Compared to what???
If you are trying to compare your Note to Apple itoy that is like trying to compare pink tricycle with pink tassels to a Corvette ZR1. No comparison at all, definitely more than apples and oranges. Having owed, well still own till I sell it, Dell Streak only other 5 inch screen out there. Agree it is still not apples to apples (or vette to vette), but Shelby Mustang to ZR1 and can say the battery performance is about the same. I upgraded my Steak to a 2400 mAh battery and had all services on and OC'ed to 1.9 ghz, yes I know single core, standard definition resolution, etc, but as close as you can get in 5 inch screen world. So far the 2500 mAh and stock ROM, with everything on, battery time is relatively the same. Will say only phone that might compare is Samsung Skyrocket HD that is set to come out this month(?), inside they are close to the same, but the screen is 4.6 inch super Amole plus.
Can anyone help me out? This is my battery on battery monitor widget. It says 1500 mah. I've only had my phone off the charger for 3 hours and I'm on 33 percent and watching it drop fast.

Battery Monitor Widget guesses at the capacity (or hard codes it). Go into the apps settings and you can tell it the battery capacity.
Also, make sure your using decent batteries. The two for $15 deals on ebay are not direct replacements. Stick with oem or brand names llike Anker.

Better battery for me. You should have done a poll
Sent from my rooted HRC Rezound
My battery life is better. But it will vary based on a lot of factors. I did somewhere around 30 firmware installs for other people. About 20 - 24 of those users have kept up with me. 2 are having really bad battery life and one more is poor but jot terrible, the really bad ones are both heavy users. They have high temp issues especially when downloading and streaming. Because I can't remotely look over their settings like I could on a computer, I can only deal with it further with some back and fourth trial and error while on gtalk. I know some is kernel related, as to why they have the heat and battery problems and others don't, I havent nailed it down.

So I've been struggling with battery life on this rezound since I purchased it. It does get hot every now and then sometimes for no reason. I was waiting for aosp to come along to determine if it was just sense or the phone itself but since its not fully operational and makes my rezound hot as hell, I've stuck with sense roms for my day to day. The following screen shots are venom Rom desensed by me, including no weather, or facebook. The only thing syncing manually is gmail. That's it. No gaming here either. Downloaded a 7mb song, listened to mp3s with headphones and cruised the web a bunch.

That's about what I had using viperrez, although it seems your phone is discharging quickly when screen is off. I'd recommend under clocking when screen off to about 500mhz that works for me. Doesn't help with the screen on time though

1.) sense 4 is a MAJOR battery hog. id advise not to use ut unless your showing off
2.) i usually get 2hrs screen on, so id say NOT defective
3.) if you want like an extra 30-60 mins, try aosp. its fast and good on battery
hope this helps
Thanks for the replies guys I appreciate it. I did forget to mention something though... This is with the extended battery I know 2 hours would be about right on standard but I would think the extended should yield more no?

Most likely yes, isn't the extended battery 1.5x? Either way, battery consumption is hard to perfect. Like I said maybe underclock or find a battery saving build. Prop script to try I know system tuner pro has one built in.

I noticed we don't have any threads about Eco Mode. I would like to hear other users feedback / experiences?
My experience:
I turned on Eco Mode earlier this morning and haven't notice any difference performance wise. Battery wise I have seen about a 10% difference to what I would be about now. (10 hours and down to 65%, whereas I probably would be down to ~55%). From what I understand Eco Mode shuts down 2 cores, essentially making it a dual-core. I ran two quadrants (Not that these matter) with Eco Mode off 7500, and with Eco Mode on 5500 (2000 difference). I also played some games and couldn't notice anything. Honestly, I wouldn't even be able to tell if it was on or off without doing a quadrant.
Based on my experience with Eco Mode I would recommend it be turned on. At the end of a charge cycle there is potential to save 20% battery life at no cost to performance (visually). As always YMMV.
For the most part I don't see much difference. I know the phone runs cooler most of the time and a tad bit more battery life. A little bit if screen lag sometimes with it on. Most of what you will ever do with this phone won't need 4 cores so it's a nice addition.

I hope we see this as well. I read a review of the Nexus 4 a bit ago over at Ars Technica, at one point they compared the performance of it to our LGOG and found the Nexus 4 faster "out the gate" but would stutter after being under load for a while (think playing a somewhat graphically intensive game). The reviewer concluded the kernels used in the Nexus 4 allowed the processor to run full boar without much of a governor so it would start to approach the thermal barrier and subsequently hindering performance. The LGOG kernels, however, were more restricted and allowed for more substantiated performance, resulting in better battery life and a cooler phone.
See review here:
arstechnica.com/gadgets/2012/11/nexus-4-two-thirds-of-a-great-phone/
I remember reading that article, too. I don't think LG gets enough credit for their Android "skin" and the thought they put into this phone. It's not perfect, but they did a really good job in my opinion.
A
I really do believe that Google rushed android 4.2. They should have added some kind of power management to the Nexus 4...
that which the hardware people giveth...the software people taketh away.
or...
you may not need all four cores today, but before end of life i'll bet you're glad you have em. i remember folks saying "what on earth would you need 512K of RAM for?" and "Why did you get a 100GB Hard Drive, you'll never need all that space."
Will Eco Mode keep your phone in dual-core mode no matter what, or does it dynamically turn cores on/off based on what you're doing?
It's dynamic AFAIK.

The os is the biggest battery user only because the screen is using very little power by comparison, skewing percentages.

I would be guessing as many people have complained about AndroidOS being out of control. However, what I was referencing was my post just above that where I said AOS should never be "MY" biggest source of battery consumption. If I get 3.5 hours of screen-on time, the battery would necessarily use more power than anything else unless there is an issue. No matter when I measure the battery stats, android os is the biggest consumer of battery. Right now I have 5hrs 35mins of charger. 23% screen power consumption with 2hrs 5 mins on time. However, I've 41% android battery consumption with on time of 3hrs 43 mins. It's a ROM or kernel thing. Not blaming our devs, they're doing the best with what they have released to them. However, there is something wrong as we should all be getting better battery life than we are with this size battery.
Sent from my LG-E970 using xda app-developers app
After having several android devices, I know that if screen on time is over 2.5 hours it should always be the highest battery usage. Also, Android OS should never be above 20%. If it is, there is a problem.

If you look at battery posts from nexus 4 users. You will see their android os % at about 6 where ours is usually 40%. Its definitely a software issue.

The Xperia u has a smaller screen,a lower clocked processor, you can't expect the amaze to be the same in terms of battery life. It's like comparing the mileage of a Honda civic and a mustang. There is no magical way to double your battery life, but you can lower screen brightness, underclock, etc
