I have been noticing that on all AOSP derived ROMs since I got the phone. I've also noticed that I absolutely can not use any governor except Interactive. Changing governors is a guaranteed lockup within 10 minutes of the phone going to sleep.
I've just been setting min to 300 and ignoring that it seems to peg itself at whatever I have the max set to. My battery life is still very good, so, I'm not entirely sure what is actually going on.
I don't have any lockup issues, but I have noticed Core 1 and Core 4 both are used pretty much in sync. I have a CPU gauge in my status bar, and on 4.3 Core 1 would alway be active the most. Now on 4.4.2 I see Core 1 and Core 4 both used about the same, and at the same times. All four get going pretty good faster now too. It's having no effect on my battery, but the phone is running much smoother overall, so I'm very happy with it.
My cpus are all over the place...

Will there be any problems with my phone if I have max cpu speed at 800 or lower?

No. Just don't expect enough of a battery gain for it to be worth it.

I use my phone in a very hot environment so I just want it to stay cool.
How much will under scaling effect heat produced?

The term is underclocking.It might help, but CPU temperatures vary with each phone, the best bet would be to just give it a try.

K I'll try that

If you haven't already, you might want to also install a widget that monitors vital stats, like temperature. I use one called TEMP+CPU Pro. It monitors CPU usage, clock speed, temperature, and available RAM and only takes up the space of one icon on your desktop.
I've been capped to 800mhz on a kernel that goes up to 1.3ghz for 2 weeks now. No problems.
Well if it makes your face smile, I run at 600mhz.

I'm currently on EXT4, VisionKernel 1.0, deOdexed EC05 and when I clock down to 600 MHz, my Epic stutters here and there.

Are you referring to your screen off setting or do you run it at 400/200 all of the time?

You can use CPU Editor, It's a script that allows you to force dual core and allows a lot of customization. For instance you can run different frequencies on each core along with different govenors and so on, could be great for saving battery life too.
If you have a dual core processor in your Windows 7 computer and one of the processing cores is disabled, you have the ability to make both cores work again. Utilizing both processing cores instead of just one will substantially increase the processing performance of your computer, which will translate into faster operations.

Root your phone. Download system tuner pro from the app store got to Cpu and change the governor to performance instead of on demand... This will use a lot more battery tho.

I actually wouldn't recommend that, in some cases performance is the better govenor for performance but I heard the S3 or the S4 processor is actually optimized for the ondemand govenor. I did some tests and I noticed that they scored pretty close to the same in the benchmarks department, I noticed that the S3 gets hot when using the performance govenor and then it starts to lag here and there but I did not experience this with the ondemand govenor.
OnDemand:
Scales CPU according to the processing needs of the programs running which saves power and is still snappy as ever.
Performance:
Locks the CPU at the top frequency regardless of processing needs which drains battery and can make the S3 insanely hot.

If you read ops request... He wants to know how to make both the cores work at the same time... And I gave him the right answer regardless of what it does to the phone he wanted to know how to do it and I answered.
Now would I recommend having both cores on at all times absolutely not... Phone drains the batter and gets pretty hot.

Naturally the second core will come on when it needs to based off the type of governor set. As said before performance governor locks at Max. SmartassV2 does not have smp so the second core never goes offline. Simply turning on the second core really won't give you a noticeable difference in performance.
But using root explorer or terminal emulator, setting
/sys/devices/system/CPU/CPU1/online to 1
Then change same files permission to read only will yield an always active second core.

Well sorry but it definitely makes my system faster no matter what these other people say. I find for instance that Tapatalk can get hung up quite easily but when I run this mod forums load instantly every time.
So, try it out and see for yourself.
Or instead of using the app (since it murders the battery life) you could just change the min frequency of your CPU to like, 600mhz or higher and it does the same thing as this app

No it doesnt do the same thing. I have my cpu set at 1800 performance and this mod clearly makes a difference above and beyond that.
And it may burn battery a bit faster but it doesn't "murder" your battery. I've been heavily using my phone with the mod on for 6 hours and have used about 40% of the battery. Pretty normal burn rate for browsing, texting and watching netflix non stop.

My S3 was getting really hot after rooting so I decided to try undervolting. I was able to under volt each clock speed by -100mv, and my device hasn't seen any performance issues, runs cool, and battery lasts way longer! What do you guys keep you voltage settings at?

It doesn't matter what other people UV since all devices are different. I can reach -125 all steps (haven't tried farther) but some others can barely do -25. It's just how their device is built.

Sent from my SGH-I747 using xda app-developers app
The reason I personally don't do both under clocking and over clocking is that the phone itself isn't made for that. I personally don't know what this phone can handle. I have seen people under clock and over clock phones and have it work while some people have phones that can't handle much at all especially the refurbished ones. My S3 handles it well but I only tried it out once. That's my feeling on the subject. If you do do either undervolting, under clocking or over clocking just remember to do it responsibly and not put it to highest power and leave it there.

I'm a huge gaming nut, I game on my pc, xbox360, ps3 and on my android phones. I've noticed that it doesn't take much time for the note 3 and it's gpu/cpu to heat up to the point where it's almost to hot to hold. This wasn't a problem on the note2 and it's exnyos cpu, I'm loving the slimness of the phone but thinking that's also why it gets hot soo fast.
I generally don't play too long, mostly 15-20 minute sessions of dead trigger 2, Asphalt 8 or Riptide 2. Anyone else notice this? I'm thinking maybe when the ZL battery comes thru and the extra bulkiness it will take a bit longer to heat up. That or maybe it's time for companies like Seidio,Otterbox etc to make some liquid cooled phone cases lol

I suppose it depends on the game but my GN3 doesnt't get too hot playing the two games you mentioned and it's over clocked. I'm on Darthstalker 3.0 with leankernal if that makes any difference.

How long are you playing the games? I'm not even overclocking, I'm on Omega rom with compulsion kernel. It's not a huge deal to me and don't think it happens all the time, could be the amount of apps installed on my phone too..

I'm not playing with the phone charging, matter of fact I just played about 4 missions on dead trigger 2 and it's already starting to get too hot. It's gotta be the snapdragon chip, none of my other phones have ever gotten this hot in soo little time.
Again I haven't overclocked or play while charging ever. This phone needs a water cooling case for reals lol

Remove mpdecision from /system/bin (but just rename it.. Add "00" to the beginning or something) and run with all 4 cores online. You will find you get better battery life and your device will not ramp as much.
This is what I do personally...
Ondemand
Deadline
io_is_busy - 1
up_threshold - 95
sampling_rate - 20000
Stock has up_threshold at 85 or 90 if I'm not mistaken, way too aggressive for a processor of this caliber.
And mpdecision is way too aggressive. I don't need all 4 CPUs spinning up to max when I open my messages app.
Also, edit your /system/etc/init.qcom.post_boot.sh file to have this line it (see picture)

Sent from my SM-N900T using XDA Premium 4 mobile app
Wow!
Did everything you said in your earlier post and I'm noticing it running way cooler now. Normally after 3-4 missions on dead trigger 2 it's getting pretty hot near the camera when holding it in landscape mode, now it just seems to idle normally.
So before I tweaked my system root and set cpu settings was it only utilizing 1 or 2 cores thus stressing more and making the snapdragon soc run hotter? These games are very graphic intensive and could use extra cores running to keep everything running more smoothly and cooler (which you have now achieved developmrntbro!!)
I advise anyone experiencing what I was dealing with to do the same and be amazed how much better it runs now, thanks again for the knowledge :good:

Trying this out as well. I don't game, but I do a lot of downloading & streaming, and the phone does tend to get very hot during. I did this about an hour ago, I'm torrenting and so far it's still not hot and the battery isn't flying out the window like it usually would be. Nice!
wow this sounds a really good idea. did anyone just include this mod directly in their rom?
So if we have 4 cores why not take advantage of all 4 from the get go instead of having to do this mod?

My Note 3 doesn't get hot like yours, unless I play a game such as Madden 25 over a 40 minute period, then it's moderately hot, nothing compared to my previous phones, and that list includes the Note 2. I love everything about this Note 3 except the camera, it has a hard time focusing on some things close up, and sometimes at a distance too, I resent the camera, I did see in another thread that I am not the only one with this problem, only problem is I did not wait for the root de la vega or else I would've ordered a replacement already.........
