Just checked, there is only activity on 3 cores. Core 0 1 and 3. Core 3 is not activating at all and there is no graph at all for Core 2. Is that normal?

Maybe system monitor has some bugs?
Maybe u turned power saving mode on?

Did you restart your phone at least 3 times?
swyped all these spelling errors from my galaxy note 2
What? Restart the phone 3 times? Why do that? And no, no power saving on!
I notice that sometimes, one or more CPU goes "offline", i guess it's a power super saving feature of the phone and not a bug. I check with system tuner, cpu 1 and 2 are "offline", i start a game, check again, and all cpu are online.

On my N7100 Note 2 (international, LJ3, rooted), every time I mount am USB stick through the otg cable, after I securely unmount it, I get CPU pegged at 1100 MHz, and no deep sleep.
To restore normal functionality, I have to reboot.
Is it only me? I have monitored cpu frequencies with the "cpu spy" application.

I'm analyzing the issue.
After umounting, OS monitor indicates that android.process.media is getting high cpu load. I've killed the process, and cpu gets relieved, and doesn't show pegged at 1100 MHz any more.
But, afterwards, the device still doesnt' go into deep sleep.
Better battery monitor indicates that "UsbStorageUnmountter" is issuing partial wakelocks, at almost full time.
How can I kill it?

I've searched in these forums for "usbstorageunmountter". It seems it's a common issue for Samsung devices.
There's the suggestion to unmount the usb stick through the settings-storage menu (in http://forum.xda-developers.com/showpost.php?p=28668028&postcount=3 ) but unfortunately that doesn't work.
Also unplugging abruptly the stick, as suggested elsewhere, doesn't work, and additionally can be dangeruous for the the file system.
There is a solution, eventually

Remember to stop the Media Server after unmounting your usb stick, otherwise cpu could stay pegged at max frequency.

Can anyone help about how to stop this Media Server? I tried with stock task manager and Advanced Task Killer and it doesn't even show it.
I have a Note (N7000) which doesn't enter in deep sleep after unplugging a USB stick. BetterBattery Stats shows "UsbStorageUnmountter" as patiial wakelock all the time. I just can't kill this unless reboot. I find frustrating to reboot phone after using a stick!
My phone is not rooted I don't intend to root it.
Thanks!
I've been noticing something with my cpu that seems strange to me. I run an app called system panel to monitor my phone for various things and I've noticed for the past few days that my second core is constantly sleeping, even under a full load it stays at 100% idle and system panel says that cpu 1 is asleep. I downloaded kernel tuner and it says that cpu 0 is active but cpu 1 is offline. Was running stock rooted with no tweaks or other things added so i tried using odin to go back to stock but I still get the same info. The first screenshot is from kernel tuner with root and the sceond is from system panel with no root. Could my phone be defective?

Try system tuner in the play store. It has an option in settings to force the second core online, all the time. Set it to always on, and set it to boot that way. At least you can test it to see if it can be forced online. It is normal for the second core to be sleeping most of the time. In your first screenshot I see a toggle for cpu1 on/off at the bottom. You accidently toggle that?
Also, what's up with your CPU temp being 32°F? Are you in the arctic tundra?
You could also try flashing a new kernel. I believe there are a few for touchwiz based ROMs. IMO you should go aosp based ROMs. Slimbean4.1.2 with asdk kernel is the best performing rom/kernel combination I've ever flashed
there is no spoon.....
I tried flashing other kernels when my phone was rooted but it kept giving me the same thing. I tried the toggle in kernel tuner to see if I could turn the second core on after noticing the issue but it did nothing. System tuner was able to force the second core on for a bit but about 30mins after boot, the core went offline and has not come back on since.
Update: found out why core went offline. Apparently, if I touch any frequency settings such as core speed or governor for either core, the processor doesn't like it and shuts down the second core. Not sure if that's normal or not. Once phone is charged enough, gonna try flashing a different kernel to see if the same thing happens when I try to change the speed and governor.

Here is a long story, but please read it all as I really think it will help explain how the two cores work together.
I had/have the same thing. Exactly as you described it. Here is what I found (What I think anyway). I ODIN'd to stock, rooted, and installed Trickster MOD. That app showed only one core working. From reading up on Trickster MOD changing any CPU settings will apply to both cores. I changed the speed, and check the info panel. It showed both cores at the same speed that I changed it to, but the second core was still not moving. I reset Trickster MOD to default, uninstalled it, and installed Kernel Tuner. Same thing. Only one core was working. I started to think it was the stock kernel, so I flashed Tiberius, Jedi, and am now on Faux123. All kernels are doing it. It's not a kernel issue, but a kernel/Stock ROM function. Here is why I say that. I installed CPU Stats, and enabled it to display the CPU cores in the status bar. 99.9% of the time only one core was working (When I mention "99.9% of the time" I mean only one core would be working for about five minutes at a time. Which would lead a person to think somethings wrong since they normally wouldn't stare for ten minutes at the phone's kernel stats trying to catch the second core come on, and think only one was working.). I did catch the second core come on very briefly, so I knew it was working even for a split second. When I did see the second one on I tried to quickly open whatever kernel tuner I had to see what the cores were set to, and what they were doing, but by the time I opened the app only one core was working. I did some thinking, and I opened Lookout and ran a full scan, opened a couple more apps that use a lot of CPU. Then I opened, and kept on top my kernel tuner. To my surprise again 99.9% of the time only one core was working. Even if the CPU load was at 100%. The second core never came on, BUT it was because the first core wasn't at 100%. The CPU load would get to 90% when the first core would hit 100% under heavy load, but no second core was working at all. I finally watched it long enough to see a pattern (Like 15 minutes). The second core will only come on when the first core is at 100% AND the CPU load is at 100%. Then the second core kicks in. Once both cores were working at the same time the CPU load quickly dropped back under 100%, and once it did the second core shut right off to leave the first core do the work. So long story short your phone is not broken. That's the way it's meant to work. In my finding anyway. I'm running the stock ROM from ODIN with Faux123 JB release 1 kernel. That's all my mods are, and running quadrant I get an average score of 3730, so I'm thinking both cores have to be working to get a score like that. Here is the Play link to the CPU Stats app: https://play.google.com/store/apps/details?id=jp.takke.cpustats
And here is what it looks like in the status bar (The last icon on the left showing both cores at max in one screen shot, and the second screen shot showing only one core working. Just to show it does show both cores working separately.):
Thanks for the explination. I watched everything like you did and same results as you. I'm grateful for everyone's input. It puts my mind at ease knowing that everything is like it should be.

It's easier to show in pics that type all the stats. Here you go:
Not sure if me forcing my second core to be on constantly did something or what but I just ran quadrant twice and I got a score of 5661 the first time and 5981 the second.
Sent from my SGH-T989 using xda premium
damn dude. Now that's a score. Obviously your battery life will suffer with that kind of performance. If still using system tuner u definitely want to turn that second core back to default. You dont need all that muscle. I run at 1.18ghz/ lag free governor monday - Friday and 1.67ghz on the weekend. Battery life is more important to me. And everything is still buttery smooth. Glad all is well, your phone is back baby.

Hi, In my apparently new Note II N7100 (Just a few months old).
I have started noticing my battery life is getting worse.
Multiple issues ;-
1) Battery self drains even when I put my phone in Sleep mode. If it was 60% at 10:00pm , it reduces to 10% in the morning by 6:00am
2) It is taking hours (almost 12 hours) to get it charged to 100%.
3) Even like unlocking phone and even opening a call log can eat upto 1% of battery.
Can anyone help please.

Hi, How long should it take? Actually, I couldn't even reach to Cache restore part. The moment I pressed the three keys (as you told), it is showing "downloading..." for last half an hour..
I don't know what it is downloading?

U have to press volume up.
Not down.
Volume down is to get download mode like what u said.

install cpu spy from playstore and see if ya note 2 deepsleep or not
if not , then :
Remove battery for 5mins and check again if it deep sleep or not ?
I've done both wipe cache and installed cpu spy.
Deep sleep mode is visible and out of my total States of 7, deep sleep add 6.
It shows 86%.
What does it mean? Can you please help me interpret?
It's it normal for this phone to run 2 cores even if we have 4. I use android Tuner and the cores will switch off. With the governor set to performance still 2 cores?

The phone saves battery. When you don't need all 4 cores to process you use only 2.
For normal usage 2 cores should be more than enough..
Sent from my LG-D855 using XDA Free mobile app
Try running Antutu or something that will stress your CPU,then all 4 cores should kick in. If not then you've got problem. The process of turning of cores when they're not needed is called "hotplugging".
Is it a known issue that HTC One m9 phones are underclocked to prevent thermal problems? Because when I open up cpuz to see what frequency the cores are running at, the highest core 0-3 go to is 1.5 gigahertz. Core 4-7 never go higher than 700ish megahertz and only 2 of them are ever running at the same time. I have a custom rom installed that enables Vulcan support, but even before flashing the rom, cpuz was showing the same results mentioned above. Power saver is turned off, there are no programs that are changing the core frequency in any way, and high performance mode is turned on in developer options in settings.
Any suggestions on how to possibly unlock core 4-7 frequencies to go all the way to the advertised 2 gigahertz? Or did I just turn on a setting that somehow affects possessor max speed?
Yo boy i have a answear for you in kernel auditor go to cores and make sure you disable core 8, core 6 and core 3 and maybe set the governor to deadline and irq blance to 0
NOW you have to go to vendor folder in system or root folder / . and delete thermal.conf or so at 10 you need to go system root /vendor and delte the file reboot and now you have unlocked full performance
