CPU Heat and temperature average

Hi at all,
Using the nexus 5 I have a 70° Celsius cpu temperature while playing a 3D game and browsing Currents.. Is this ok for the phone? Or its dangerous?
What is the maximum temperature of the cpu without damaging the phone?
Thanks for your help and sorry for my English, any correction is welcome!

Hi,
70°C for the CPU temp is "normal" when you paly a game. Remember that we have a quadcore at 2,26Ghz without any cooling system...
In any case there is the thermal trottling to prevent any damage. According to the CPU temp (and also the battery temp) the CPU freq decreases automatically.
Also there is an hotplug routine according to the temp (cores offline at a certain temp).
The last "ultimate" thermal protection is the shutdown at something like 100°C (according to the thermal-engine.conf file it "should" be above 100°C, but...).
So no worries there is a protection and your CPU temp is not abnormal.
One among the others: http://forum.xda-developers.com/showthread.php?t=2597508.

The phone will not let itself achieve a dangerous level unless you have modified the kernel to tell it not to thermal throttle at 70.
the frequency throttle temperature is 70 celcius the suspend temp is 65 and core throttle is 80

Thank you!
I should have guessed that there is a system to prevent "overboiling"..
PS: I used the search button with" temp" and "temperature" but I haven't find thread.. I guess I don't know how to use the search button
Thanks for your time

Thermal throttling and hotplug settings

I have been able to fix quite a bit of thermal throttling experienced in multiple benchmark runs by tweaking with the thermal-engine configuration file. With just a few changes and with the copper shim mod I can now run geekbench for as many five times with almost no drop in score. After that I get no thermal throttling in single core but I have it setup to disable two cores after it hits 55C CPU temp in core 4 and 7. I use CPU Z to see actual CPU temp from the sensor readings. Even after 8 Geekbench runs the two cores are still running at full speed and the phone is registering 44C. It's warm but not hot by any means.
If anyone is interested in playing around with it just look for the file in \System\etc\thermal-engine-8994.conf
Most of it is just two adjustments. One for Max temperature at which it will throttle and the one below is the temperature at which throttling stops.

Without your copper shim mod have you found any better but safe values we can try?
At least no thermal throttle until 55 celsiius

It should be safe without the copper shim. The thermal pad it comes with works pretty well. It will still thermal throttle to whatever temperature you set it at so it won't cause any harm.
I've set the Big cluster to a max of 65C and a single A57 core to up to 71C and haven't had any problems yet. I used to get horrible performance with PPSSPP emulator. When running Tony Hawk Project 8 in PPSSPP after 30 seconds of gameplay It used to drop to 6fps and now it can sustain over 20fps after reaching 71C on a single A57 core. I only saw a maximum battery temperature of 40C and the device wasn't noticeably warmer than it was with the default thermal settings.

Well yes. Except that's the little cluster and they don't get that hot normally. It's the big cluster that needs to be modified. I also tuned my display thermals so the screen wouldn't get so dim when the phone gets warm. Here you can look over my configuration if you want.

Thanks i will try them!!

your settings somehow "unlocked" my phones cpu. lol in geekbench I found an increase of performance of 200 points in multicore from 4020 I had before maximum , now nearly 4300 .It is impressive. also if I run 6-7 geekbench in a row there is a decrease everytime ex 4200 4050 3900 3600..... but temperature stays 45 degree.
I will test them more later.

Thanks for sharing your results. That's the highest multi core score I've seen on our phones. I never gotten that high of a multi core score. Glad to help. My configuration also tweaked the battery thermal settings so now you should see faster charge times as well. The default charge rates had really conservative thermal settings and the high speed charge would drop after a while but now it will 2.2 to 2.4 amp charge through the whole charge.

Yes indeed i saw a difference in chargin thanks for your effort in the configuration. I am not very fond of benchmarks but i run some in my devices after magor changes (firmware....). This device should have been speedier because of the full hd snapdragon 810 combination. I wonder if we delete the thermal config is the device gonna be speedier? I am waiting for 5.1.1 hoping for smoother rom. Lets hope soneone unlocks the bootloader!!!! I took my precautions disabling MLT lol

I guess it depends on what you're doing but I probably wouldn't play any 3d games with those settings. Here's a copy of the original one https://www.dropbox.com/s/yb76q6qwanb9ujr/thermal-engine-8994.conf?dl=0

When you apply the settings you need to give time to the phone to 'absorve' them.
Run a couple of benchmarks, test a 4k video, reboot the phone 3-4 times, close it also.
I havent noticed higher tdmperature of 45 celsius.

I'm not sure what would happen if you just deleted the file. Maybe it'll revert to some default, or perhaps it won't thermal throttle at all which would result in auto shut off when it overheats. Probably not worth risking it without a custom recovery in case it doesn't boot.
I have notice that my phone is way quicker now. It was fast before but now it's a beast when I push it hard. Also things like PPSSPP emulator was useless with the default thermal throttling now it can beat my Tegra note 7 with 4 A15 cores at 2.1ghz at it.

Was there a problem with your settings? I noticed your settings you had shared on dropbox are no longer available.

The folder was deleted for some odd reason. I was able to restore it so the link should work now. Let me know how it works out for you.

A few questions about these settings.
-At the top where you have SS-Little_Cluster_management and SS-Big_Cluster_management is the set point the shutdown temp for the entire cluster?
-I think this one is self explanatory by the action listed but towards the middle where CPUx_MONITOR for each core is, is the threshold the temperature at which the entire phone shuts down?
-I'm not sure I am noticing the difference between SS-CPUx and CPU_HOTPLUG_MONITOR. Could you explain these?

I don't want to assume I know everything about this. Everything I know about the thermal configuration file I learned from seeing others modify the LG G3 thermal config file. I also learned some by experimenting with my G Flex 2.
In my understanding SS-Little_Cluster_management and SS-Big_Cluster_management is the temperature at which the Cluster will thermal throttle when all cores in the cluster are being used at once. From what I've seen anything with "action_type 10000" means thermal throttle. The closest thing I can think off that works like that is how Intel I5 and I7 will limit turbo speed when more than one core is being used. Except in our case this is to prevent higher speeds when it reaches a certain temperature. So lets say your phone is running some heavy multithreaded app now it's going to follow the rules set in Cluster_management. The default Big Cluster temperature is set to start slowing things down when temperature reaches 48C and to not go back to full speed until the temperature drops down to 38C. One thing I find interesting is that at about 48C cluster temperatures was about where the Big cores would drop to a max of 1.5 ghz. So I'm just guessing that this setting may play a big part on the big cores max speed.
[CPUx_MONITOR] seems to shutdown the phone when the core reaches a certain temperature threshold of 120 C and I assume will not allow it to turn back on until it drops below 115C.
[SS-CPUx] on a big core seems to slow the specific core down when it reaches a temperature threshold of 85C and to not allow it to go to full speed until it drops below 55C. However this rule can be overwritten by [CPUx_HOTPLUG_MONITOR] which can shut down a core even if it hasn't reached it's maximum temperature threshold.
[CPUx_HOTPLUG_MONITOR] just tells the specific core to turn off once it reaches the temperature threshold specified. On the default configuration core 4 and 7 are set to turn off when their temperature goes above 50C. After that core 5 turns off at 58C and even core 6 turns off at 61C. At which point only the small cores will remain on.
I hope that helps somewhat.

Overheating leading to lag

My Nexus 5 runs smooth as butter until it starts heating up. As soon as the phone becomes warmer and warmer, the phones performance slows down.
This has nothing to do with gaming, etc. I keep installing new ROMS every 2-3 days so the phone is formatted anyway.
I only use browser, YouTube, whatsapp, listen to nusic and use few other apps. I don't play any games.
What should I do? Is this expected from Nexus 5 anyway or is there a solution to this. I also replaced my battery recently.

You could underclock and change thermal throttle temperature to a lower value and get some thermal paste and apply it to the actual CPU which takes 10 minutes to do

Under normal circumstances, using the phone for about 15-20min (normal app based usage, nothing heavy) causes temp. to rise upto 73 degree celsius.
Room temperature over here is around 28 degree celsius.

Yes should be fine but the paste absorbs the heat and helps dissipate it where @Kotaless has provided the numbers than can really help if you don't want to underclock

Can disabling thermal throttling harm redmi k20 pro? (Using SyberiaOS) (CPU at 77 C)

Currently I am using SyberiaOS for playing games and have noticed that while setting thermal profile to gaming mode. The CPU temps get to 77 C and sometimes even 80 C. Though the battery temps are below 39 C. Then i performed thermal throttle test using the play store app and noticed that in the gaming profile, the CPU doesnt ever throttle which got me concerned and made me realize that in this mode, CPU throttling must be disabled.
My question is while using this mode (No CPU throttling)for 30 mins-1hr, can it damage my phone Soc, screen, etc in some way?
I play genshin impact and within 7 minutes, the phone CPU reached 77 C.
I use CPU meter to check cpu temps.
The CPU seems to maintain at 65 C at normal thermals. (With default mode).

High CPU temperature? Nothing will happen to your phone. Don't worry. When CPU temperature goes too high then Android is smart enough to throttle CPU usage at its own or even to shutdown the phone.

What I am worried more about is other components of the phone. Since, while using the CPU throttle app, it didnt seem to throttle even once, so the only option here is The HW level Soc shutdown under high temps.

Must admit I don't understand what your issue is.
By disabling thermal throttling you may damage your device and at the very least will invalidate your warranty.
As previously said: There is no need for thermal throttling on phone at all, hardware does a good enough job clearing the heat.

There are modules designed specifically for gaming needs. Here are a few for testing purposes.
A phone’s internal temperature can be 36-43 degrees Celsius (96.8-109.4 degrees Fahrenheit) and still be considered normal.
Arguably, its fine, if anything that's considered "cool" considering the chips can withstand up to 90°+.
The temperature reading you're seeing is simply the "system" temperature. The CPU and GPU hit well above 90c on games like Genshin Impact, there is nothing to worry about as those chips are designed to run these high temperatures. If high temperatures on SoC's would have been as damaging as some people make them out to be all devices would have been dead by now, but they still run despite thermal throttling at almost 100c nonstop.
-- YMMV

Taking any sensor above 160F isn't a good idea as a runaway component frying temperature excusions (caused by temperature control hysterious) can and do happen. You need a buffer zone to help avoid this...
High temperatures and current drain trash Li's prematurely as well. Any constant drain of 800 mAh or greater will effect battery longevity. Some of these newer phones are drawing an average of 1Ah when not even gaming, ridiculous.

Thanks, I've tried some magisk modules in the past but none of them works and some of them bricked the phone and I couldn't boot up without formatting it, I'll need to make a back up before trying any of these so I won't loose files again.

If the humidity is low use a damp microfiber cloth to cradle it in. If the battery goes above 108F it may trigger throttle back even shutdown.
It likely will not charge above 104F.
Keep it out of the sun, always. Use manual brightness control and keep it under 50% whenever possible. Optimize it and take out the trashware like FB, WhatsApp and such.
I can use my phone at 100F for prolonged times with no cooling for browsing but need cooling for vids or such as well as charging at those temperatures.
