[Q] gs3 thermal paste

hi everyone, a quick ? does the galaxy line of phone have thermal compound on the cpu or gpu? and if so is it possible to replace it with some prolimatech pk-3 thermal compound? i know when i did the thermal compound swap on my laptop my temps went down 12 deg C. i notice a difference in the warmth of my phone when i overclock it past 1.7ghz. so i hope the temps will drop on my gs3 if i can put some on the cpu and gpu.

[Experts] How to change temp. tresholds ?

Hello, my XS is overheating and throttling the CPU.
I have 7400 points on Antutu at room temperature (around 25* deg.), and 8500 when in the freezer. Apparently it's a mater of a few steps - it works fine up to 37* battery temp, then it drops the CPU to 1134 MHz at 38*. It doesn't go any warmer. I want to change the treshold to may be 40* or 41*. I don't believe it can cause any damage, and I'm willing to experiment. How do I do this ? Is it hard - coded ?

Go to system/etc and open thermald-semc.conf. In MSM_THERM category change in the line "thresholds" the number 55 to 65-70(depends on how much you want). Now your device will throttle the cpu when the temp will be 70d. Save and exit ,reboot.

I changed the line over cpu as well - only by 4 deg. It doesn't throttle anymore! Many thanks!

Thermal Daemon Mitigation?

Can someone please explain to me what Thermal Daemon Mitigation does?
Does it effect the CPU throttling or something else?
I've searched online but have had little luck with an explanation as to what it does.
People have been saying to turn it off to increase performance, so thought I'd find out what exactly it is I'm turning off
Cheers guys

Bump.
No one knows what the Daemon setting effects?

You're pretty much spot on with saying it has to do with heat and CPU throttling. Thermal Daemon Mitigation is what causes your CPU to under clock itself when it reaches an unsafe temperature. Unfortunately for us, LG thinks an "unsafe temperature" is anything above ~50 degrees Celsius, the point at which I have begun to notice severe under clocking. The Snapdragon 801's thermal safety level is ~90 degrees Celsius, which means the phone will more than likely freeze or reboot at this temperature. LG has attempted to save battery life and avoid the dreaded overheating warning by prematurely and preemptively throttling the CPU when it goes beyond an otherwise reasonable temperature.

Some say it's dangerous interfering with those settings..Others say it has improved their phone performance without blowing up their phones..
I'd suggest you read a bit more here and here
Read users comments and make your own decision. I've tried it for a few days but I eventually turned it back to it's original state. :good:

I thought High Temperature Property stopped the throttling. Do they both throttle?
Haha this is why I got confused.

I do not see a high temperature property setting anywhere in the build.prop or hidden menu. I am using the Verizon variant (vs985) though so there may be some differences there. I would assume the high temperature property regulates the temperature at which throttling occurs; that is, if it is an actual value and not a True or False setting. The thermal daemon mitigation build.prop value is what actually turns the throttling on or off. By definition, a daemon is a service or background process that runs independently of the user to monitor and maintain software or hardware aspects of a device. Mitigation literally means to reduce the severity of something. Your post got me curious so I decided to be brave and turn the Thermal Daemon Mitigation Off setting on in my hidden menu (the setting has the word Off in it so turning it on technically means you are disabling the mitigation). I used my phone for the entire day and I didn't seem to notice any adverse affects on temperature or battery life under normal circumstances. I did notice a substantial increase in performance under heavy load, however. On stock kernel settings, I went from an Antutu score of ~38000 to ~41000 consistently. My phone's temperature, however, did top out at about 92 degrees Celsius, which is almost the boiling point of water and is right on par with Qualcomm's safe temperature limit for the 801 SoC. Other than benchmarks though, my phone stays around 50 - 60 degrees Celsius which is fine by me. Just be warned that you may experience some excessive heat under strenuous load, but Qualcomm's own built-in thermal protection "should" keep your phone from melting itself. I emphasis "should." Just so long as your battery isn't getting too hot along with it your phone shouldn't burst into flames.

Off / Enabled?
Ok, sorry if this is a stupid question or if it has been asked before, but just wondering...
The setting is called "Thermal Daemon Mitigation OFF"
So if this setting is set to "On" - does it
a) Stops the throttling of the CPU?
or
b) Enables the throttling of the CPU?
It's just the wording of the setting is getting me confused
Same with the "High Temperature Property OFF" setting - would setting it to "On" disable or enable the throttling (or whatever it is the property is supposed to do)

Thanks. Was guessing as much, just wanted confirmation. :good:

So is it safe to enable both setting? it wont fry our phone or any other component?

As with any mod there comes risk but most of us have nothing but good to say from enabling this option. yes factory says of which means enabled set both to on to disable throttling. most ive ever seen is 72 c which is pretty warm to me i average 50 to 60 i did the thermal mod arctic silver paste on the proscessor which helps too

I tried Applying the thermal paste on processor (ram actually) but then the screen got hotter. so I decided to take it off... (I dont want to damage my screen)

Yea the screen does feel hotter but imo its also displacing heat from the pross its kinda funny i was one of the ones that had the yellow spot on my screen since i putnthe paste its disapeared and not been back in 2 months but in the end its prefrance

cpu temp @ 100c+ in negative weather.

Just wondering if its normal for the temp sensor to read 160c+ in -10c weather.
This happened when i was walking home. Cpu reports extremely high temp and just wondering if this effect any performance.
Bell, htc 10, boot unlocked, S-OFF, 1.90.666.4

.....

Wondering if it's a false reading. Can you download another app that monitors CPU temps and see if there are any discrepancies between the two apps?

Wow,that's really interesting. For my information, are you holding the phone in boiling water?

Probably a false reading. Your battery is too cool for a cpu this hot. Also cpu gets permanently damaged at temperatures this high. Either a sensor is damaged or app giving false reading.

that's because of the minus 10°C outside ^^
This has happened quite a few times for me when i used the phone in the freezer.
the CPU sensor somehow doesn't handle minus temperatures very well. Because the battery is constantly used it heats itself up and does not go into minus temperature.
The SoC itself is often in DeepSleep or almost idle. So it doesn't draw that much power, not enugh to keep the temperature over minus degrees, especially with an aluminum body that sends the complete outside temperature inside, not isolating like glass.
Don't worry about it
If you're curious you can install the app Stability Test https://play.google.com/store/apps/details?id=com.into.stability
It heats up the CPU pretty fast, then you can find out what's the lowest normal temperature the sensor can recognize ^^
P.S
You probably cannot damage a CPU due to heat. On my old Xperia Z2 i tried to disable ALL Thermal throttling, and run a Stresstest, when the CPU temp reached 91°C the phone simply shut down. Emergency shutdown to prevent overheating damage. Not sure if it's from Android or CPU hardware protection.
Most Intel CPU's do have a hardware protection, wouldn't be surprised if Snapdragons had the same.

with no OC (AKA 2GHZ + 1.5GHZ) I got 81c, with 2.2Ghz + 1.7Ghz I hit 92c but it kept going with no throttling

95c, i made a video

If you do that next time can you do me a favour and get the dmesg?
If you want to you can "dmesg | grep [THERMAL]" to make it smaller.

For those who are having erratic batter percentage!!

Hello xda,
I have been having the erratic battery behavior for a long time [i have the tablet for 3 years now].
I have sent it for maintenance on warranty and they changed my battery but no use!
The erratic behavior occur mainly while playing games i.e gpu workload....
But there was no kernel that allowed me to undervolt the gpu untill now
I flashed lineageOS with the tool deathly auditor and set the maximum gpu freq. To 420 mhz
The problem was alleviated but not completely resolved.
I also used battery HD app to monitor battery percentage and battery volatge during playing games and what i found is interesting.....
The battery suffers sudden sever voltage drops while playing gpu intensive games
This was alleviated by undervolting and decreasing maximum gpu freq.
I hope this helps someone regards.
Rydj

I also forgot to mention that i soldered the battery directly to the board but that didnt help either
As it was thought that the erratic battery behavior was due to cracked soldered joints of the battery connector.
BUT I CAN CONFIRM IT STOPPED SHUTTING DOWN AFTER I SLAM THE BACK COVER!!

Thanks for sharing
I also have the same problem.
I gave the note to my son and got myself a tab-s2, he is not so happy with the battery.
If he plays non intensive graphic games battery lasts hours, but a bit of graphic and its dead in an hour.
Can you please share your undervolt and max gpu numbers?
Do I need to undervolt and change cpu governer too ?
Are you on Nougat?
OP says:
GPU Control:
GPU Time in States - Same as CPU Time in States (Times in each frequency)
GPU Frequency Control (not yet supported on Nougat)
GPU Voltage Control (not yet supported on Nougat)
GPU Governor Control (not yet supported on Nougat)
