OK so I know pie devices get relatively hot, but when just having my screen on and typing on here or using root explorer it goes up to some 90 degrees. And it just concerns me because my galaxy s2 hardly guys 90 even while playing intensive games.
I'm just curious if 90 is normal or if I should get a new device through warranty.
Thanks everyone.

When I was using SetCPU, I saw mine hovered between 80-90 most of the time. If it is bothering your hand, put a case on it. I use an Otterbox Defender and I can feel the heat through the case sometimes.

In my experience this generally hapoens either after a new rom flash or just at random (seemingly). But it has always eventually calmed down and stays cool after that.
I suspect it is searching for mor something....like updating libraries of songs and whatnot. Seems like it occasionally gets stuck and when you add additional load it easilyy heats up. Try using Show CPU Use in dev options and keep an eye on the top few processes while it heats up. May give you an idea as to the real cause.

after enabling what you had said, I couldn't notice anything out of the ordinary. Surfaceflinger was the only one that was always up. But that's absolutely needed. I'm hoping it settles down after about a week.

Mine is also dimmer than it was on ICS. After the OTA update I noticed it. Did factory reset with same results. Formatted everything and applied the rooted version through odin and still have them dimmed LED. Updated my brothers S3 and his is the exact same. I got a text message last night and the LED was fully illuminated, but after I opened it and received another message after it was dim again.
This needs to be fixed I'm very ocd about stuff and this is fine of em

I always thought they needed more power? but they are more efficient as using this power?? I dont remember its been forever since ive studied electronics
Anywasy, on topic, i run CM10 and dont think its all that dim. Maybe they added an option inside the settings for brightness? I wish it had the "breathing" option instead of just flashiing. But check for a setting maybe?

Not really positive about details. I think they are more efficient. Whether they use more power I have no idea. I know our utilities company is offering to take old Christmas lights and they give you LED strands instead for free.

Single color LEDs are quite efficient. These multi-color, variable brightness LEDs are somewhat less so. That doesn't really matter the question at hand though because most of the power drain of LEDs is just having them on. The difference in power drain from a low intensity to a high intensity is marginal.
Everything is supposed to load much faster. It's getting rave reviews in the playstore. Is it really that noticeable or placebo effect?

At first I noticed no difference but I ran a few test like turning animations off and running apps with and without seeder then did the same with animations on and I do notice a slight speed up when opening apps. Not a huge difference because like someone said this phone is already a speed demon, but there is a slight increase, but then again could be placebo lol.

I posted this on another topic as well that was discussing the seeder app. This is straight from a CM Dev on G+.
" The entropy pool stuff is bull****. The only users of /dev/random are libcrypto (used for cryptographic operations like SSL connections, ssh key generation, and so on), wpa_supplicant/hostapd (to generate WEP/WPA keys while in AP mode), and the libraries that generate random partition IDs when you do an ext2/3/4 format. None of those 3 users are in the path of app execution, so feeding random from urandom does nothing except make random... well... less random"
A lot of tech talk but he goes on "The only reason devices feel faster is because by constantly polling the PRNG, it keeps the device's I/O in constant use (which in turn, depending on device, will make the CPU stick to higher clock frequencies to keep up)"[/QUOTE]

How is this useful? To anyone wondering if it will work or is curious: install the free apk on xda. Try it out. If it helps: great keep using it. If you want, buy the play store version to support the dev. If it doesn't work, good you didn't waste your money now you can go spend your buck and some change on a pack of gum or a soda.

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.

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'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)

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.........
