supposed solution to heat during gaming .

i want to discuss the overlock or underlocking the cpu
so whats the effect on heat generated ????
overlock increase heat or dcrease heat ??
and is undervolting helps to decrease heat generated from the processor ??
many tests mentioned that overlock 1.6 is stable and undervolting scale (200-800) is also stable but non of the testers mentioned the heat effect all are reporting for stability and speed
i suffer from heat during hd games and i know it is normal but i dont want the phone to get hot during gaming i closes the game after around 30 minutes due to this problem

If you want to reduce heat during gaming, then you need to change the 1.2GHz speed (level 0) down to either 1.0GHz or 800MHz. Changing the Level 1 to Level 4 speeds won't solve your problem since your CPU will be at full speed Level 0 during gaming.

srry i dont understand what will make the processor return to full speed 1.2 during gaming ?? if i set it to 1000 or 800 ???

No that's just bull****. Go play around a few games and have CPU Spy running and after a gamsing session check the CPU states, rarely does a game go over 800MHz and most of the time spent is on 500MHz for most games. There aren't any games out there that need the computational power of higher frequencies and that's why their time-in-state is procentually so low.
If you really want to reduce heat, then you need to undervolt your GPU which right now is only possible with a Tegrak compatible kernel, which is frankly speaking out of date, or you wait a few weeks until the Ninphetamine team finishes GPU voltage control interface and then more kernels will be able to implement that.
While undervolting with Tegrak I was running 160MHz/750mV 266MHz/750mV full stable (default voltage 950/1000mV, 750 was minimum configurable). It was running full stable and while on default the back of the phone would get really hot, while undervolted it was just warm to the touch.

so is there any effect on device performance ????
after undervolting the hd games performs properly as stock ?? and without heat ?? if yess i will root now and see what can i do
and how can i know that my kernel is tegrak compatible ?? it is kg2

Changing voltage has no effect on performance unless you undervolt into unstable values and make it crash. Stock should be compatible with Tegrak (I think???). Just check out the free app in the market. The stupid thing is you need to pay for the full version to get GPU control and that's why it's unpopular, so maybe it's just better to wait for Ninphetamine GPU control in a couple of weeks or soonish and have it for free and get a good kernel to go with it.

thanks bro
but i think i have small thing that confuse me undervolting is different from downlock ??
and what is the relation between them ??? i think certain volt will give related amount of "Mhz" ?? is that right ??? so set cpu is the same effect as tegrak or what ??
srry im new to android

Tegrak, basically gives you more options such as GPU clocking and custom tweaks. SetCPU is ok, but I just use it for controlling clock speeds. Also, you can set oc'ing, max at 2GHZ, but you have to play around with stuff.

Use a very thin case and you'll never notice.

Sure. I just fired up Plants vs Zombies, which is not the world's most demanding Android game and played 1 quick game, taking about 10 minutes. While playing, the back of the phone just where the camera is became warm through the phone case! Tell me why I have the phone running at 1200MHz for such a big portion of time if my post is just bull****. This was also the Last Stand level, where you get a pause in the middle of the attacks to replant.

35% of time on full speed does not equal all the time on full speed like you said in your first post. It's still 50% on either 800 or 500MHz like I said. And you took a bad example as I dont even know if PvsZ is even using properly the GPU, and then might use only the CPU. Go play Gameloft HD games which are the most demanding atm and max CPU ratio to the rest falls down.

so what ??? at the end undervolting will help or not ???
i need it for hd games
and if the cpu need to be at 50% of time so it need to use 1200 mhz 50 of time so if we fixed it to 800 or 1000 or 500 this will affect performance

no heat issues
I have ninphetamine kernel, underclocked to 800 and undervolted, I haven't noticed any heat issues since then when playing games and noticed no slow downs. Games tried: HeavyGunner, Zenonia 3. Also no heat issues anymore when playing flash video in a browser.

but sorry these games are not using graphics as eternal legacy or asphalt 6 hd or fast 5 hd

really it works
i rooted then set cpu then put the values 200-800 and asphalt 6 worked around 20 minutes no heat at all only slight warm
and the benchmark only decresed from 3300 to 2750

[Q] What is the safe max temp for LG G2?

I checked this but I did not find it asked/answered here, I kept getting results of other devices.
I am running this modification my G2 and it seems to get hot pretty quickly. I have a case on it and I can feel the heat very easily, gauge is reading 103*F. I know this may not be too hot for other devices, I read 107 or more, but what is the safe temp?

thats only 39C its hot but not dangerously hot. 50C+ is when you need to get worry
you better off install a rom and wootever kernel and UV its...I rarely reach 35C

so all the other time you play asphalt it never got that hot?
did u play it with a case all the other times?
could be background process running along with your game causing it to be hot.

Since I downloaded it today was the only day I played this long (just 3 races in a row and some browsing here and there on the game screen, that's all) so I don't have any comparison data but I was just curious as to why it got hot so fast. It never felt this hot (hot enough for me to check the temperature) doing anything else, except maybe when I ran 4-5 benchmark apps in a row, I remember it felt pretty warm back then too but cooled down quickly. Also I did not hold the phone on hand when tests were running..

just try it again, if it get hotter than 40C then your thermal paste might be ****ty and might have to return. if it kept stay around that temperature then your fine. I wouldnt worry about it, but like i said, i rarely get up there.

Thanks, I am going to give it another run tomorrow after it is fully charged at %100 I am going to play the game for about 10-15 minutes report back with temp.
Then I will let it cool off, close all unnecessary applications and then try again and report back.
Is this actually battery temp or processor temp? I assume it is processor because the hot portion is actually top, right around the camera. Should I be checking any other temp gauges?
What rom are you running? I wanted to root and run a rom, but it seems like all roms are either nightlies or release candidates, there isn't even a stable 4.2 rom for G2 D800.
Edit:
I just saw CM 10.2 has finally been released as stable but there are still some reports of serious bugs, and a poster said this should be final before development on CM 11 begins.

Hi,
Do not confuse CPU temperature and battery temperature... Here guys (at least hydeah) you are talking about battery temperature, not CPU temperature.
40/45 °C for battery is not abnormal, an average 70 °C for the CPU temperature is not abnormal when you are playing games for example. In any case there is a thermal throttling to prevent a real overheating...
And according to the Thermal files in /system/etc the max battery temperature is 52/54 °C (and 120 °C for the CPU before shutdown)...
These threads about temperature bother me, even all the threads wich reports "overheating" are all expect real overheating, but only misinformation or whatsoever...
Guys you have a quadcore at 2,26 Ghz... what do you expect playing an heavy games 30 °C CPU temperature and 20 °C battery temperature???
With this mod (http://forum.xda-developers.com/showthread.php?t=2479892) it's normal that your phone runs a bit warmer, the max CPU temperature before thermal throttling is increased to 70 °C...
But in any case the thermal throttling still exists...
There is plenty of thread like this one, use the search function and you will see that your temperature is normal.

Thanks, what do you recommend to read both cpu and battery temperatures?
I did use search function, but like I said there were a lot of threads on other devices/models so I wasn't sure if they would apply to this particular device.
120*C? Won't things start melting and boiling at that temp?

I use Trickster Mod, you can try this one too: Temp+CPU PRO, System Tuner, etc...
But with these apps understand that you have a range CPU temperature, it won't be exactly the temperature at 1 °C precision. Maybe you'll see 70 °C in reality the exact and real temperature will be 68 or 71 °C for example...
Yep, high temperature limit and confirmed from a kernel dev (the "old" Samsung Galaxy Nexus have 110 °C as max CPU temp before shutdown for example, I push it to 100 °C max ), it's the internal CPU temperature. But I guess it's (almost impossible) to go so high, the thermal throttling is present to do its job before...

Merci beaucoup monsieur.
Too much work at the office, couldn't run the tests today, will do it tonight.

the G2 will start thermal throttling when its core cpu thermostat hits 150 degrees.

the G2 will start thermal throttling when its core cpu thermostat hits 150 degrees. Which sucks because most benchmarks will get your CPU up around 160-170° It lowers the clock speed to 1958mhz at first then if needed as low as 1152mhz to prevent damage.

Testing a weird kernel tweak. It's working and I don't know why !

ROM: NEAT ROM 4.4.4
KERNEL: gustavo_s' kernel for AOSP version 04 Feb 2015 with Synapse.
So one day when drinking beer I thought to myself: if Ondemand is so sensitive in jumping to higher frequencies, why bother setting the threshold low? So I just simply went to Synapse and set the up-threshold to 99%. Naively I just thought it was to make sure the CPU was full until it needed a faster frequency. To my surprise, a few days later was fantastic: the time my GS spent on high frequencies was so good it looked like I was using conservative, the least time was on 1200MHz and goes up along with lower frequencies. And the performance was intact :silly::silly::silly:
:silly::silly::silly: can anyone confirm you had tried this before?
One last thing: I just enable GPU rendering, I read that GPU used more power so it is not efficient but on this kernel I am able to use 54MHz and 66MHz which only drain 800Mah which is less than the voltage of 200MHz. My first feelinng is that scrolling through Manga app no longer lags. Will this work as I expected, guys? :silly:

Using gpu in lower frequencies may unstable phone. I use @Gustavo_s kernel too. My first frequency step is 108MHz and 800mV can easly handle this. Lower frequencies only slows phone. Enabling gpu rendering also causes overheating on AOSP roms on i9100 belive me I tested.
Edit: Also 99 is a high value. 85 to 95 is ok.
Sorry for my bad english too..

Yeah I may feel that right, I'm switching to 66Mhz and it feels better, yet I don't think GPU rendering causes overheating, it felt the same, I'm turning it off for comparison a few days... :silly:

I assume you don't care about gaming performance or any graphics intensive tasks? Don't see why this is a weird tweak, but it is still a noteworthy tweak that may help people who want raw computing speed but no gaming.

That's right, don't have any single game, but I'm very very into multi-task. Switching from app to app in seconds... so that obviously works for multi-task people.
I recently switched to intellidemand with the same setting and notice the CPU spent even less time on the high frequency, but it begin to has lag so I think ondemand is still my best choice right now

Major Speed Increase

I have noticed this phone underperforms compared to other Snapdragon 821 devices and I have found a method to majorly increase the speed of this device.
After the following changes the device remains running at cool operating temperatures and performance is increased over the board about 50%
Doing these changes will disable the useless thermal limits set by Xiaomi on this device. Xiaomi set the limits far to low unlike other manufacturers.
The device still has hardware thermal protection by Qualcomm so there is no chance these changes will damage your device.
Your will need:
ES File Explorer
Kernal Auditor
Root Access
Open ES File Explorer and navigate to System/etc
Scroll to the bottom and find file thermal-engine-8996.conf
Copy this to your sd card for a backup and delete this file. ( This will not take effect immediately )
Go to Kernal Auditor and change the big core CPU Governor to OnDemand and set the Maximum CPU frequency to 2150MHz.
Set the LITTLE core CPU Governor to interactive and Max Frequency to 1593MHz.
Go to GPU and change the GPU Max Frequency to 560MHz.
Restart your device for these changes to take effect, the changes are astounding and matches the performance of a stock Snapdragon 835 device while still running at standard operating temperatures.

are u sure, we will have same thermal sensation ? i mean in hand ?

Wont it make the device very hot and will have very fast battery drain?

The device doesn't get any hotter than usual with these settings.
It is important to under clock a bit so it can keep this sustained performance without breaching it's thermal limits.
The performance gains are very noticeable especially with Dolphin and PPSSPP.
You can see how hot the device gets with Kernal Auditor. Compare the heat listings before the changes and after these are done to check for yourself.
As long as you use these settings the device will not get hotter than stock.

The device doesn't get hot if you underclock the cores and battery life is even better because you are underclocking the GPU and LITTLE core which don't need to go up to 2.1GHz for standard tasks.

There are always down sides to system modifications that haven't been extensively tested, his mileage may not be what you get - be very careful changing core restrictions / settings.

I find there can be considerable variation based on the ROM. I have found EPIC to give the most consistent results. By results I mean Antutu, since general performance is hard to measure.
I set the cores to their max and the boost frequencies to max too. Governor is on demand for both. Response after touch is set to 100ms. In the thermal settings I have Temperature Throttle on and the GPU governor to performance. I get 155k In Antutu almost every pass. Sometimes it'll top 160k, other times down to 150k.
I don't care about the heat since I almost always use the included case and I'm not concerned with battery life. The main thing that still bugs me is the temp figure in Kernel Auditor. It'll show high 60s after Antutu, but other temp apps like CpuTemp show it never gets above 45C. What does your temp get up to?
From what I've read, even in the 60C+ range it's still within safe/reasonable working temps for the CPU. I've used these settings for around two weeks​ and I've gone out of my way to game when I rarely did before (sometimes 1-2 hours in PPSSPP which taxes it). Never had it freeze/lock/reboot once. My Nexus 6 would occasionally do that when I had it pushed to the limit.
If I didn't use the case then I probably would back off it a little as you have outlined as the temps when holding the bare phone can be pretty hot.

In the thermal settings I have Temperature Throttle on and the GPU governor to performance. I get 155k In Antutu almost every pass. Sometimes it'll top 160k, other times down to 150k.
I don't care about the heat since I almost always use the included case and I'm not concerned with battery life. The main thing that still bugs me is the temp figure in Kernel Auditor. It'll show high 60s after Antutu, but other temp apps like CpuTemp show it never gets above 45C. What does your temp get up to?
From what I've read, even in the 60C+ range it's still within safe/reasonable working temps for the CPU. I've used these settings for around two weeks​ and I've gone out of my way to game when I rarely did before (sometimes 1-2 hours in PPSSPP which taxes it). Never had it freeze/lock/reboot once. My Nexus 6 would occasionally do that when I had it pushed to the limit.
If I didn't use the case then I probably would back off it a little as you have outlined as the temps when holding the bare phone can be pretty hot.

Kernal Auditor gets the actual CPU/GPU temps , I'm not sure where apps like CPUZ or CPU Temp get their readings.
Even after running Dolphin or PPSSPP for a couple hours the CPU temp gets into the low 70's but that's as high as it goes.
These chips are safe to run up to 95 C for CPU , 100 GPU and 110 C for the battery.
Changing these settings keeps the device well within it's thermal limits.
I have had my phone set like this for months after running it many other configurations.
I just had to tell everyone about it because it beats my buddies OnePlus 3T quite a bit when it comes to gaming.

Give it a try and see for yourself.
I recently upgraded to the latest epic ROM version and found my phone to be running extra slow and battery wasn't lasting as long.
Turns out the update had reverted my settings so I decided to post this thermal "fix"
I highly recommend everyone make this change really , there is a reason that OnePlus decided to underclock their OnePlus 3T and why it runs much faster than the Xiaomi Mi Mix before this fix is completed.
It's all because the thermal throttle kicks in much too early on the Mix due to the extra heat at max Mhz for the GPU and large cores.
The only way to change this and get the performance enhancements is the remove the thermal file as I posted and follow the steps to ensure good thermals.

Thanks. Done here. It got REALLY REALLY fast but so warm for now. I'll wait to see if it get colder...

Tried these mods right now.
Simply wonderful.
Antutu from 130.000 to over 157.000
Increased speed
Now all is very smooth
But the temperatures, incredibly, are gone down...this smartphone now is more fast and more cold.
Xiaomi/Qualcomm thermal control is so bad?
But there's a strange issue with Kernel Adiutor: I set the frequency, governor etc but, after reboot, I see these settings returning to original values. Is it normal?

I also have this problem.
I have set everything and the "Apply on boot" is on but everything is going back to the original values.

Really? It was so warm here. Like 80 degrees celsius. Would it be cause im using RR?
Sent from my MI MIX using Tapatalk

I had the same temperatures with miui, RR and Lineage.
If I delete that file in every rom, i think I have the same results: more speed, less temperatures

I will try this settings on My MIUI ROM...
@ all...
Tips to have Kernel Adiutor to apply @ boot value (on MIUI ROM i mean)
Go to security center and manage permissions for this apps like auto startup authorized after restart i see a notification with time which say, i will aplly your value in xx seconds... and it works...
@NGP-1001
Thx for your feedback and tips, will make some test on my daily usage and send my feedback too...
Cheers

Dolphin the browser? The only other Dolphin I know of is the one for GC/Wii emulation.
Low 70s is as high as mine gets too but it can get uncomfortably warm without the case. Maybe it's just when the CPU and GPU are both being pushed that the heat builds more. If I just use a CPU-only benchmark, like GeekBench, the phone only ever gets moderately warm at most.
I was really disappointed with the general stutter and performance (just in the UI, not even gaming) before I noticed your old thermal post. I can't recommend this method enough. Getting rid of the thermal.conf makes a massive difference no matter if you underclock it or push it to the max, even if you're taking a hit on battery life.
For those on the latest EPIC, the integrated Kernel Auditor is gone, so it needs installed from the Play store. Even then it won't work on boot like the old one did. You need to go into Settings > App Settings > Permissions > AutoStart and toggle it on.

Great result with performance governor

O, i need agree, device is much smoother then before, if u don't play, u will have a standard temp ° but i try to play Battle Bay... Got damn, baby...
Hot like a woman in video clip from old west coast sound... 84.2°... based on demande request, if u play, device come hot, other it's cold...
Will try more time to check if i can adjust temp limit to reduce speed based on temp limit...
Cheers

If anyone is still getting higher temps I would try underclocking a bit more. You will still get the speed increase even at much lower MHz. I wouldn't use the performance Governor as it's a huge battery drain.

So.. why should someone Overclock his Phone?

So here’s what I got: It’s not about getting more power out of your processor. It’s something else..
As a PC Overclocker, getting more power out of the Phone’s processor was the first thing I thought was behind Phone Overclocking. But that should be impossible right? I mean.. how the hell are you gonna cool that thing? You can’t.. And it is. That’s why benchmarks give you the finger after you OC your phone. At best you’ll get about 15% more “points”, which of course is laughable.. But then again why do people do it? Is it a fetish? Well it’s not. It’s about these three things:
UI Reaction Time – UI Animations Smoothness – Memory Management
Three things that determine the quality of your daily experience with your phone.
Every vendor makes his own adjustments to the Kernel that determines the behavior of the hardware in response to the software. Some make it right, some don’t. And when you find yourself hostage to the latter, the only way you can break free and restore your phone’s true potential, is with a custom Kernel that allows you to adjust it. And it’s not even necessary to increase the frequencies! Tightening the timings, or even better eliminating them, can make all the difference in the world! But since a Mobile Chip has a built in protection against overheating, and raising the frequencies could not possibly harm it, then what hell.. why not?
And that god damn memory management that doesn’t let you have more that 4 - 5 apps in the background, even though you have 4 GB of RAM!.. what the hell is that! Well you can fix that too.
So you see, appearances can be deceiving. Phones are different creatures that the PCs. We do different things with them, so we need different things from them. And if you’re willing to give up just a little bit of your battery life.. man..you will NOT wanna go back!
So that’s it!
PS. Speaking of battery life, there is also that thing called “Underclocking”. It can even double your battery life, but of course the price would be the exact opposite effects of the above. Every man has his poison!..

That is false. Even with thermal protection, the lifespan of the cpu can be drastically reduced if its overclocked and constantly running hot.
And many users overclock in order to get a better experience playing games.

That is true in general. It's called electromigration and it doesn't matter if you cool it well enough. It is caused by the increased kinetic energy of the electrons. But phone CPUs don't get stressed enough to see it happening. Even in PCs where actual overcloking takes place, it would take many years to actually see it happening, and a very serious increase in performance.
So in comparison one could say that it really is safe.
One interesting thing that someone said to me last night though, is that custom kernels don't have a perfect temperature throttling when necessary. So one should check the temps in the initial stage of testing to make sure that it doesn't get too hot.

I would've disagree with that. Overclocking used to work reasonably well a long time ago but for about 10-15yrs the headroom in desktop cpu's have shrunk and overclocking does not give stable results. My own experiences coincides with what I've heard with people who work in IT who build/sell pc's - overclocked cpus will encounter much more errors and intermittent problems and will require resetting back to stock clocks or even underclocking in order to be stable.

Check this out for example: I underclock my CPU to 1689MHz from 2000MHz, but I change the governor to Performance, which keeps the cores constantly to that frequency WHEN operational. The result is a MUCH snappier behavior with no apparent latency, zero stress to the CPU, and battery compensation by the lower frequency.
Could you do that otherwise? That's what I'm talking about! Full flexibility!

Thats not overclocking and you did not talk about flexibility. Even the title of your thread says "Overclock".
You said overclocking cpus on pc's and phones were safe and would take "many years" to see any degradation.

I said both of them, and they do not conflict with each other. I explained it in my first post.

Underclocking is a bad thing. unless you can't overclock much because of battery and temperature limitations, underclocking is not recommended. It depends on your governor, a stupid governor will slow you down and be visible on weak devices. your case is due to have stupid governor in phone, but suitable with strong device & want to save battery but don't need to lock freq at maximum

cpu will not degrade in life no matter how high frequency, overclock and runs continuously but its life cycle will be affected by high temperature and high voltage
