In order to squeeze even more juice out of the note 3 battery I have recently installed CPU Tuner after rooting. Has anyone starting using this app with their note 3 and what is best settings for best performance/battery life balance?
Guess not but was a good thought....

And can anybody compare it to the Galaxy Nexus, or an iPhone 4/4S (a 4S WITHOUT the battery issue that was going around)?
I'm really interested in switching from 4 to either a 4S or the a Note or Nexus... Battery life is an important thing to me though.
Also, just how much does having blacks on the screen help? How much does that help? If you just wanna answer my first question "How's your battery?" then that's fine. That's what's more important here.
Compared to the iPhone 4, I am getting almost twice the battery run time. I have not changed my habits during my normal day, and use the same apps that are available for both platforms by the same authors. The black home screen does help if you are starring at it all the time, but how often are we doing that?
I am also rooted and using FM kernel. Love the Open Source community.

Some site did a comparison of 3g talk time with a Note and an I****.
The Note got a whopping 14 HOURS of 3g talktime.
The i**** 4s got 8 hours.
So phone vs phone, thr Note wins.

Holy cow! What's your screen-on time? Are you underclocking or anything? I'm guessing your good battery life was because of the kernel?
even @ stock ROM and Kernel, the NOTE is impressive in terms of batt life except if you're browsing a lot (since we all know that AMOLED consumes more juice in showing white shades compared to other display technology) ... Some ROMs and Kernels have battery saving scripts embedded and you can also find a lot of tips on how to improve batt life on our Note...
In my case, my Note can last 22hours+ of moderate to heavy usage; im using Rocket v6 ROM and FM Kernel (undervolted and underclock to 1200mhz)... I set my Wallpapers to the darker ones, customize goSMS with pure black background and themes, disable fast dormancy, turn off GPS and wifi when not in use, use minimal widget as possible, set the brightness to lower level that suit you, set to GSM mode mostly, disable background data when not needed, delete some unimportant processes in the system, manage startup application, disable task manager, and etc...

Yes, the FM kernel did help significantly. The reasoning being that the author disabled the heavy logging Android does for debugging purposes. Other than that, everything in the kernel is stock. No undervolting or underclocking. I also keep away from any app that overclocks the CPU, they usually mess with the phones ability to go into deep sleep.
Screen on time: 4:29m
regarding deepsleep and unwanted processes in background; you can install CpuSpy, Watchdog or Wakeclock monitor app if you're having an abnormal battery drain...

CPUSpy is a wonderful lil app. That is how I determined that SetCPU broke the phones ability to go into deep sleep, even after uninstalling it. I had to flash the ROM all over again.
Compared to iphone 4 gnote battery is less... the reason is bigger battery.
However even with heavy usage my battery last till night every day.
battery life has got better with time.

true... the apps i posted are all essential IMO... wakeclock monitoring is also very helpful in finding faulty apps running...
I'm getting glorious battery compared to my GSII.
Granted it's relatively light usage for now because of work and such, but I'm impressed. Almost always have the brightness at 25%, never need any more.
The sudden drop was from a restart.
My battery life was fine until Google started selling apps for 10p, I downloaded Jelly Defence and I became addicted to playing it...
...Who seems to be getting worse battery life since I've rooted and installed CM10 and Franco Kernel than stock.
Before with stock I was only losing about 1% every two hours on standby (sometimes even better I've no idea how)
Now I'm losing about 3% an hour on standby and also about 30% an hour screen time with just basic browsing (Screen brightness set to auto).
Also Media server is hammering my battery. Like I lost 3% battery in 15 mins without the screen on just playing music (not streaming) is that normal, I've come from an iphone 4s which didn't lose that in an hour :S
have i flashed it badly is there something else maybe i should try or are these stats about right ????
thanks guys
That's just the way it is just custom roms. When flashing, put your head between your legs and pray for the best. You can spend hours trying to figure out what's gone wrong, but you might never get an answer.
You can try underclocking your N4. Currently my dual-core Snapdragon S3 T-Mo Galaxy S2 is underclocked to 810MHz from 1.5GHz and performance is still great. I'm guessing you can UC your N4 to at least 1.2-1GHz and performance will still be great because of the quad-core Snapdragon S4 Pro CPU. Also, what governor and i/o are you using?

Hi Gents
Thanks for the reply, yeah it does seem a bit of a hit and miss kinda situation, I'm not masively bothered, im hoping eventually someone will stumple across a fix for the way the screen murders the battery life but im not holding my breath. Still love the phone, really getting used to it now, have tried (and failed) many times to switch to android, must be honest, this is the closest I've come so far to waving bye bye to ios, android is really really fantastic as an os, it's also super pretty to look at these days, stock apps like contacts, calender and the phone app itself are beautiful.
Let the phone and battery have several cycles, it will improve, eventually
thanks mate !!

Under clocking your phone isn't a viable situation. It's a phone, what's the point in it if you're not going to use it to your fullest when my phone lasts through the whole day going from 384-1500?
Some battery tips for op:
- download better battery stats (Google it for a xda version) use this to debug wakelock and ensure your phone is deep sleeping under cpu states. You can also use cpu spy to check cpu stats. Better battery stats is a must need.
- disable Google latitude in maps. Disable the automatic reporting and any other checked marks
- disable Google now cards that you have no use for
- disable gps (some apps use gps and drains battery when it keeps using gps when it isn't necessary)
- ensure your governor is interactive and on latest version of Franco (r20 is very good)

Just stick with the stock kernel that comes with cm10.

Highly advise doing that. Other kernels are way more optimized whereas CM is focused on the ROM itself and not optimizing the stock kernel.
I believe CM10 uses stock Google kernel anyways (could be wrong).
Use Franco Kernel or anybody elses kernel that you choose to.
Mine definitely improved after rooting and flashing custom ROM. Battery life when I was still stock was horrible.

A ROM has very minimal battery life improvements, it isn't as significant as a kernel. Hence the definition of "better"
Hey guys I just got a Nexus 4 with a cracked screen for $50, I just fixed it also.
I love the phone, I cut my AT&T sim to fit it.
I've just got a few general questions though:
If I disable two CPU cores, will it still be a snappy phone? Kinda like the S3? I mean the S3 has two cores right, not 4. Would it improve the battery life a lot more?
In the battery mod thread I've seen, I asked if anyone has the 3D model for the backside of the phone(to add another battery). I was wondering if anyone has some info on this? I would gladly risk this phone for an extended battery
What app could I use to disable two cores? Is there a kernel for 4.3(jss) that does this?
Thanks,
goatocean

As far as I know, it's only using all the cores when neccessary, so if you're worried about battery life just reduce the number of apps you use. I'm using the Purity rom now and easily get a day out of the battery.
As counter-intuitive as it sounds running more cores in a multicore CPU is more power efficient than running a few cores in most modern multitasking systems. You're spreading the process load over multiple processors that can be run at a lower clock speed than a smaller number of cores running harder.
Well drooling over the Ok Google feature of the moto(always listening).
Is it possible to make a kernel that would have 3cores running max, and 1 core running 196mhz?
Then make an app that's using that one downlocked core to always listen. I wonder what our battery life would be though
Hi guys,
I'v got exynos version of note 4 and the battery life is awful. 3 to 4 hours of screen on is the highest score it can reach. Do you think if I change it to snapdragon it would be better ?
Exynos note 4. 3rd day with the phone. Stock ROM. WiFi on sync on.

You'll need to root, install a ROM and Ultimate Kernel v9. It'll improve it a lot.
For the record there's no difference between the SD and Exynos re battery life.
I started doing this just for experimental basis on my note 4 without root after lollipop update.
1. I encrypt my phone.
2. I activate knox protaction under security, i just ignored warning about activate this feature will affect performance.
Results i like to share is...
No problem in performance.
Antutu score around 50k.
Antutu stability test shows fentastic.
Amazing battery life.
In my opinion u can try this, if you don't like very well u can revert back.
U can select finger scan as a password for screen unlock.

What launcher do you use? I am on BOC5 (XSG). But my battery performance is terrible. Daily its on low to moderate usage but battery runs out faster than when it was on KK.

agree on using nova prime. I did not do what the OP said but we have the same note 4 variant and i'm having a great battery life. 8hrs. SOT and 18hours on battery.

Now others also activated knox protection & their antutu score gone high on lollipop.
