I need somebody's help. The coolest my Note 4 CPU/GPU seems to get is about 53 degrees C and that's when I turn it on after it's been asleep on my desk. It is not a rogue app or anything like that because I have done both Factory resets and I have install custom roms, so everything has been factory reset multiple times. The water damage sticker indicates no water damage whatsoever. I know phones can get hot when gaming, my Note 4 gets to anywhere between 70 to 85 degrees Celsius and I am just wondering if that's normal I reduced my screen resolution to 720P and disabled two cores of the quad core processor and it does not seem to help one bit. Is this temperature normal or do I need to get rid of the phone?
PS when doing normal browsing it seems to hover around 60 to 67 degrees C
And the battery does not seem to go over 37 degrees Celsius

Okay, so I got rid of my Note 4 so this is off of memory (full-disclosure). My Note 4 always ran pretty hot when it had to do anything. When flashing ROMs I'd be lucky if the CPU was below 70 C and any time I'd be playing a GPU intensive game it would get too hot to touch. I never had a lot of issues with the battery temp being too high though despite this.
As far as solutions go:
1) Screen res might help.....but I would try my other suggestions first
2) I wouldn't recommend disabling cores, it just makes the other two have to work harder to accomplish the same tasks and may be worse overall.
3) Kernel adiutor will allow you to do two things: adjust thermal throttling and adjust max GPU/CPU frequencies. I always reduced the max GPU frequency on this phone to lower the temps and adjusted thermal throttling to 55 C. The only CPU adjustments I did were to make sure the CPU wasn't overclocked.
4) I know you said it wasn't a rouge app, but get a task viewer (this is a good one) just to make sure (I had Nova taking 25% CPU usage in the background because I restored it from TiBu).
I saw your post in the NSeven thread and decided to respond, but please in the future try not to post errors in other threads unless you have the issue in that ROM. It sounds like you might have the same issue in that ROM as well, but you didn't say so in your post.
Well first of all I would like to say thank you! I have been hoping for a while that someone would have some knowledge on the subject and I very much appreciate yours. Secondly, I apologize and I will try to refrain from posting the wrong thing in the wrong area in the future. Thirdly I have kernel auditor when I changed their frequencies on my CPU cores they just change right back. If I set a minimum it will stay but then if I try to set a maximum it resets them both to the default setting. I will turn my other course back on though thank you for that information do you have any idea why I may be having this frequency issue?

You're welcome, and no worries for the post . As for your third point it would be really helpful if you tell me what you're running.
Could you list: kernel, ROM, root method, Android version, and any kernel mods (govtuner, skynet, etc)?
Also, does the same thing happen when you set a GPU max frequency? Have you tried having the settings run on boot and then reboot the phone?
Yes I have tried that a couple of times I am currently running the nseven ROM with the CPU frequencies set at a minimum of 300 megahertz and a maximum of 1190 megahertz, or at least that's what I'm attempting to do LOL I have not tried changing the GPU Max frequency. The N7 ROM I believe is Android version 6.0.1. here is what I have tried
Wiping cache in recovery
Starting in safe mode
Factory resetting
Turning off certain settings such as WiFi calling, data Etc.
Using apps such as greenify to limit background processes.
Changing screen resolution to 720P
I actually installed this ROM hoping that it would make a difference because I have the same exact issue on the stock ROM before I ever unlock my bootloader or rooted my phone at all. And according to the sticker on the back of the phone it is not nor has it ever been water damaged. The picture I have attached shows my phone's activity just while writing this reply to you. In the bottom left-hand corner you can see the statistics. Sorry for the Inception lol

Since you're replying to both threads I'll keep my responses to your other Q&A thread to make life easier .

I'm looking to optimize my battery life without sacrificing performance when I need it. I know it sounds easier said than done, but I figure that if anyone might know how, they'd be here. My goal here is to have the performance when I need it, and to keep the battery preserved when I don't.
I'm rooted and running ViperROM 4.0.4 Trinity v2.0. I have the "Genocide 1.2GhzOC EB13 Kernel v0.3a" kernel also flashed to my phone. SetCPU is installed and I've set up my profiles, but I think I may be doing something wrong with them.
I am using autodetect settings as is recommended for adjusting clockspeed. Everything is set to on boot. All profiles are set to conservative as I'm not sure which ones actually apply. Below are screens for everything I have currently set up.

Am I doing anything wrong here? And if not, is there anything I need to do to improve battery life without sacrificing performance?
I would bump your charging max to 1200Mhz and keep the min at 1000Mhz, although I keep max and min while charging through AC power at 1200Mhz.
Your screen off profile is fine. If you get hiccups or missed calls for any reason, bump the max up to 400Mhz.
If you can run it smoothly, set your minimums for your battery profiles to 100Mhz. It what I'm at now and it runs fine. You may want to keep your minimum for your "screen off" profile at 200Mhz if you get hiccups or missed calls like I mentioned before.
As for your battery <50% profile, I'd set the min at 200Mhz if you're wanting to save battery. Don't want the phone running at a higher clock when it doesn't need it. That's the point of running the min lower.
I personally uncheck the "set on boot" to allow SetCPU to always come back to the appropriate profile rather than going back to the default setting.
Also, set a Battery < 101% profile which will be your new default. I have mine at max 1000Mhz and min 100Mhz and it works well.
Also, conservative simply means the battery will remain at the lowest possible clock until it needs more juice. Assuming it starts at 200Mhz, it'll bump up to 400Mhz, 800Mhz, etc. depending on what the demand is. It will jump frequencies from 200Mhz to 1000Mhz if necessary.
On Demand means the CPU will either be at your minimum set clock frequency or your maximum.
On Demand is usually the most compatible/stable, but the conservative setting is best for battery/performance if your kernel allows it.
Hope this helps =). Let us know if you have more questions.
EDIT: The "set on boot" button simply sets the min and max that's shown on the main screen in SetCPU. If this button is unchecked but the "enable" button on the profiles menu is checked, your profiles will still adjust accordingly.
I can't really see the profiles but do you have the Max set at 400 when the battery is under 50%? If you do your phone will crawl. The 1000 is undervolted. That way you get speed and save battery. And on demand does not.mean that your CPU is either at min. Or Max. It means that it Scales faster then Conservative does. My profiles are when battery is less than 50% I go to 1000/100 and when screen is off I'm at 200/100 all set on demand. My regular setting.is 1200/100.

I'd like to hijack this since I have a similar question.
I'm using ACS Frozen 1.0 and have the latest SetCPU and am still getting pretty crummy battery life.
The weird thing is that in SetCPU the maximum CPU frequency is always 1.2ghz even if I drag the slider down to 1.0. I don't currently have any profiles enabled that would cause this, so why won't SetCPU let me top off a 1ghz undervolted instead of 1.2ghz?
My battery life definitely hasn't improved at that's a big bummer for me :\
I also have a question. I kept getting a message about superusers rights not being given. I searched to see how to grant SU rights, but could not fond any. I turned the phone off and on, and that message did not pop up anymore.
Now the main screen I cannot adjust any of the numbers, is this normal? I can however enable and make profiles. I made the first one if temp is greater then 0 (I obviously do not want it like this, but its just a test) then it should be OC to 1200. When I saved this in the top right hand corner it says I am at 1200, however when I bring up a program, and go to setcpu and look at the main screen it says 1000.
So what am I doing wrong.

Yeah I hear you, I get the same crummy battery life with SyndicateROM, I was dying for the 30 hours ! Starting to think it's the battery itself.

Do you keep your 1200/100 on conservative? And what's the battery life you're getting on average? Dummy question but you know...
I'm going to try out this setting today actually with BakedSnack.
Referring to those of you getting "crummy" battery life. The screen takes so much battery many other things don't come into play. Therefore, if you're getting 4-6 hours of screen-on time, you're getting about what everyone else is getting. Those who report 30 hours+ probably have there phone idle more often than not.

Did you update to the latest Twilight kernel? It's 1.0.1 I believe. Try that as I believed it fixed some CPU scaling issues. Just install the zip in CW, but I'd still wipe cache at last, just in case.

+1 I think this was a bug with the original release of Twilight Zone that was fixed in 1.0.1.

I'm trying this out right away, thanks!
This whiny message brought to you by the letter E for Epic 4g
ok so im running the STOCK GB but im rooted and have been running gingertiny 9/29 ran into rebooting issues.. phone constently reboots after 20 mins of use. usually when this happened before like on stock kernels the battery temp would rise up to 104 but i kept eyes on the temp and it never goes over 78.4 F
not overclocking cpu im actually running at about 625 mhz but issue still occurs
SO with that being said i need help finding either a better kernal or trying to find solutions with this one.
i went back to complete stock and rooted to see if i still have this issue
any help will do thanks!
These questions belong in the Q/A section. This has zero relevance to development.
Now:
1) pull the battery then place it back into your phone.
2) Charge it awhile to make sure you haven't dropped a considerable charge during the bootloops.
3) Turn your phone on and move your clock speed towards 998400 (stock clock speed) via setcpu or however you underclocked.
This bootloop is likely due to you being underclocked so low. If you want, flash Tiny's latest kernel from 9/29/2011 to bring yourself up to date.
Was your min clock speed underclocked below the stock 245000? I had random reboot issues when I underclocked my min to 128000.
Having your max_freq set at 628 or whatever it was shouldn't cause reboot issues. You're phone should be rock-solid stable at a speed like that. I'd suggest taking a look at your voltages.
I've never run that kernel so I'm not familiar with what the voltage table looks like, but it might very well be that your voltage is too low. If your max_freq were higher, the transition through that clock freq would probably be too brief to cause an issue. I don't know if that kernel has sysfs enabled, but if it does, upping the voltage at that step .25 volts should cure it.
Min speed was at 628 even switching back to stock kernel still having issues I'm not sure what can be the issue I only last few mins playing any games or watching anything all speeds are stock

Sounds like it's time to start wiping stuff.
This is something that i have noticed and have confirmed several times. Ill be downloading a rom ( as im currently doing at this moment) and i get a average of 1.6Mb/sec with the screen on. I turn it off the screen for 30seconds or so then back on amd my live data graph in System Panel shows it imediately reducing my data speeds to around. 5Mb/sec or 500kbps. As soon as my screen is back on my data speeds are right back to 1.6Mb/sec area. How could this be? Im just more curious than i am upset that my phone does this. Thanks in advance for insite some one may provide in regards to my question

Are you using cpu scaling? Perhaps when you turn your screen off, it's forcing the CPU speed down to 200mhz and that is slowing down your connection transfer? Just a guess..

How do i check what my screen off cpu state is? Im running Caulkin's 2.8 and i know his is 200mhz-600mhz screen off. But im using Rom Toolbox to keep my cpu max at 1ghz so maybe that is changing the screen off cpu mhz?

Actually i have found out that rom toolbox doesnt over ride it. CAULKINS battery script always seems to take over as long as you dont check the box "apply on boot" i tuink im going to dive into Tegra app for my underclocking. Heard its great and i love the idea off a slow cpu clock of 800mhz and a higher 245mhz (i beleive) gpu clock. Best of both worlda. Smooth screen and extra battery so to low cpu clock
I'm on stock, rooted, s-off
my device is getting extremely hot during normal use.(i dont play games at all, just whatsapp, facebook, news etc..)
sync is off, auto brightness.no google location reporting and history, no google now or history.
and using bbs to see what is going on ,i have no wakelocks and looking at battery screen, screen on time and awake time are almost identical.so nothing is keeping my device awake.
but for some reason, when the device is idle, the cpu goes nuts!
i installed cpu status bar xposed module so i could monitor cpu on real time, and i see the device jumping allot from 300mhz to 960 and 1000+ for no reason.(without touching it, and no apps running).when i touch the screen it scales to maximum.
it drives me crazy because i dont understand why the cpu behave like that.there is no logical reason for cpu going to max when i'm typing text.
its unbearable, cause its getting really hot while i hold it.
i have tried various kernels(elementalx, skydragon, faux, ionx, hacker kernel, but all of them shows that behavior.
on my old i9100, i never got that behavior, ondemand governor was perfect and i could reach 4 hours of screen on time.with the m8, i can barley pass it , going for 4-5 hours, because its draing too fast.
any suggestions?
*EDIT*
tried a factory reset, and i just installed xposed with cpufreq status bar module, and the device is still going nuts.WTF?
Can I ask... are you sure this is abnormal? I mean, are you seeing ill effects? Is the device laggy? Is your screen-off battery time awful?
All OS's do stuff in the background, and "idle" doesn't really mean anything at all to be honest -- even when you "don't have any apps running" there are apps running, and you'll always see the CPU cycle from idle to low speed to high speed if you're looking for it.

i know there are background process and apps, and i don't except the device to stay at 300mhz all the time, but its quite annoying to hold on to a device and feel its temperature rising to insane levels without doing anything fancy with it.just texting.and every touch ramp the cpu to the max frequency, its weird.and unnecessary.
i don't know if its normal behavior, as i mentioned, my old i9100(galaxy s2) would not act like this. and i could get 4 hours of screen on time, and here, i get 4-5 hours max.it dose not seem logical.
I'm not using lte of nfc or BT.my reception is full(both wifi and cell).
i just want to know if this a normal behavior? anyone else having this heat buildup on light use?
I have a similar problem there on M8S. I killed half the background tasks, disabled syncing, auto backups, and then I open FBreader(or any other app) at 30% brightness and all the cpu cores go to 50 degrees C, heat up my battery to 43 degrees C. It results in loss of 40% of battery charge in just an hour. With screen off my device usually consumes 1-2% an hour. Whatever I do, I have never seen at least one core sleeping, they always work at 600-900MHz.
First of all, Hi everyone - chefs, users and admins!
I am writing this post with a really heavy heart now, almost bleeding experience happened to me from nowhere about 2 months ago. I feel quite an advanced "flashoholic", however I've broke up with that few years ago. In 2013 I sold my Note 2 and started "new life" with Android, bought a DSLR and engaged into photography. This year, in february I have bought a tablet as I needed really something for business purposes, and I have chosen a Tab S 10.5 LTE. I didn't ever hear about any Knox tripping or anything, and as soon as it arrived I flashed a AOSP ROM to my thingie as I love AOSP overall. Than strange things started to happen with my CPU. As I recall I have noticed it first after installing Xposed to the tablet - it started heating pretty badly. When I checked my CPU states through ROM Toolbox etc I noticed it sometimes freezes at frequencies around 1.7-1.9 GHz, and during this behavior max frequencies could even fluctuate from 1.7 to 1.8, 1.9 and so on. It looks like "something" changes max frequency setting of CPU as it wants, whenever it wants to and pushes usage to the maximum.
Now, I started to look for a fix - uninstalled Xposed, every root apps etc. Nothing stopped it. I was "pretty sure" the cause is in AOSP thing and the conflict between my hardware and custom AOSP Roms. So after 2 months of tryouts to solve the problem, I today reflashed TW to "finally" get rid if this and save my battery life. What shocked me was... the bug is still here! Even with 0 apps installed, all ROM stock and clean, my CPU goes crazy, the back is hot, and CPU monitoring apps show a hard usage of 1.9 and 1.8 GHz frequencies. At this point I started to panic.
To mention - before I posted this here, tried to search over xda, googling it and so on, but it seems noone has such problem anywhere! As long as I know I can't get my warranty back, and I feel really panic and don't know what to do. I am asking experienced devs or anyone who faced it before for some help, on my knees. This tablet is great, but pretty useless when my battery hits 20% after 4 hours!
EDIT
I snapped a screenshot of some kernel options I don't understand, however someone maybe would find any wrong input here (as I can change them thanks to the app). Thanks. PS. I have changed max fr tp 550 in order to avoid heating and battery drainage, to this moment thayt's the only way I know to stop it.
Thank you very much for any help and advices, and sorry for my bad english.

Hi John, it looks like that option doesn't work. I see that none of apps exceeds CPU usage over 10%, but the clock still goes on 1.7GHz etc. Sometimes it cools down, but it happens rarely.
Did you adjust the setting to monitor all phone processes, even if you have an wifi only tablet still do this.

Thanks but umm.. nothing happens. Tried holding down task switch capacitive button for few seconds on every tab, but it just goes to task switch view.
Strange, I just hold the button down and within 2 seconds the strip along the bottom of the display appears, maybe you are in the wrong mode, there are three section on the top of the screen, you need to select the far left one called STATS.

VERY strange. I did it on all 3 tabs, just nothing happens. Is it possible that app changes maximum frequency of my CPU? I don't believe any app has possibility to do it on it's own...
Have you tried it again with watchdog on the same screen in my screenshot then press the button, watchdog does not change cpu frequency.

I used to have the same problem on AOSP roms and some Touchwiz roms! When you first flash it and set things up, CPU usage is fine. But after a few days maybe hours, CPU would do the same exact thing like yours! Then my device gets hot and drains battery.
I found this to be a problem with AOSP 5.1.1 roms. Resurrection remix, CM12, PAC ROM and yeah. Never had problems on Cm11. The only ROM that solved my heating issues and no cpu problems are AOSP roms on 5.0.2 or Liquid Smooth rom. 5.0.2 was bug free. Liquid Smooth ROM has an custom kernel which helps cool down the device and reduce the high CPU usage. Seems to be the only ROM without issues for me on 5.1.1. For Touchwiz roms, I just install skyhigh kernel and turn on hotplugging and CPU multicore power saving to solve heat issues. But really on Touchwiz roms, CPU is fine most of the time for me.
My device is SM-T800 BTW. This is what I found out from flashing many roms.
