[Q] phone is getting hot.. how much heat it can handle??

recently i have bought yu yureka bu micromax
- 1.5.GHz Snapdragon 615 MSM8939 Octa Core Processor / Adreno 405 GPU @ 550 MHz
- 2 GB RAM
- 5.5 Inch HD IPS Touchscreen Display
- Dual SIM Support
- 13MP Primary Camera With LED Flash
- 5 MP Front Camera
- 4G LTE
- 2500 MAh Battery.
- Customizable Cyanogen 11 OS
the phone been heating alot.. the CPU temperature is normally 45C and it raises as we use.. when gaming it goes between 60-65 C and when i run benchmark tools or play heavy games over an hour the temperature goes above 70C the top i observed is 77C..
isnt a processor supposed to shut off at 70C? as for safety reasons till it cools down?? how much this snapdragon 615 processor can get the most? will it burn or burn other internals?? please some1 clarify my doubts! i even noticed many people are facing the same kind of issues with samsung and moto phones which runs on octa core processors.. is it a hardware related issue or a software issue???

No It will not burn any material. It is not the PC Processor, but it seems that your device heats a lot, may be it is a manufacturing defect. Try asking others with the same phone. And don't overheat your phone, dont play games for hours and hours
Hit thanks if helped

i dont play games that long.. with this device its hard to play for more than an hour.. 90% of the ppl having this device facing the same issue but most of them seems to be not caring.. some even said the snapdragon615 can withstand up to 100C is that true??
the customer care ppl said...

I can't find any temperature values on the qualcomm website. Just write a email to qualcomm for first hand iformations Phone's kernel works with thermal throttling, means depending on the actual cpu temperature the cpu clock is lowered to protect the cpu from overheating. If your hardware works as it should, you can't overheat actual processors by using I suppose. If you can find a custom kernel you probably can set own values for thermal throttling. In any case you should try a kernel tool e.g. Trickster Mod or Performance Control for setting up the cpu. If you think its getting too hot, just deactivate some cores or lower the cpu clock, your phone will still be fast enough for all your applications.
Edit: which customer care people told you about the issue?

70-80 Degrees isn't a "Worry" Moment, It's actually quite normal for a Octa core to reach that high what do you expect? Since a phone doesn't have a Fan or something like a PC, so it relies on something else which needs longer time to cooldown.
My Nexus 5 using Quad Core reaches almost the same Value (65-70).
Remove the case if you have one since a case will have your phone increase in temperature too.

thanks.. i already hve done it.. i bought a flip cover which i used only for an hour... i worry only when it exceeds 70C.. i can feel the heat near the cam.. it gewts hard even to hold it. i heard meadiatek processors doesnt heat only qualcomm processors does. is it true??
is there any other phone with the same kinda heating issue? like over 70C still survive??

They've got no email addresses only office locations https://www.qualcomm.com/company/facilities/offices

then i guess only the experianced/developers in this forums can help me.. all i wanna know that if its safe to have such high temperatures ( 65 when gaming and 75+ when running benchmarking-stress test) is it ok with this qualcomm anapdragon 615 processor... some said these processors can withstand upto 100c and 90c is the cutoff temprature unlike the old processors.. can some expert who is experianced with developing any apps for any quad/octa core processor out there please help me. i just want this much info only

[Q] MTK 6752 Overclocking Possibilities?

Now, I know and full Mediatek Kernel source codes are few and far between, which means that custom Kernels for said devices are also very rare. But is it possible to modify the kernel on a phone without needing the source code?
The MTK 6752 has a maximum frequency of 1.7GHz in most devices, but the upcoming 6795 which has the same cortex A53 cores, will be able to reach 2.2GHz. Providing there isn't a physical limitation (such as the Moto G Gen 1 where the frequency was physically capped at 1.2GHz when it was theoretically capable to reach 1.6GHz), shouldn't this mean the 6752 could be safely overclocked to 2.2GHz? Obviously it may need more voltage / produce more heat based on the chip binning, but disabling 2 - 4 of the cores (which largely go unused) should balance out any heat issues.
Is there any kind of Xposed module, flashable .zip, or any other kind of mod that would enable overclocking? I know Tegrak overclock worked by directly modifying part of a device's stock kernel which is where my thoughts originated from, but that program only supports a limited number of devices.
So is overclocking of the MTK 6752 possible, in any way shape or form? I have an Elephone P7000 on pre order and if I could get that running at 2 - 2.2GHz even if it were only on 4 cores... well, that would make the upgrade from my gen 1 Moto G even more sweeter

My processor is slower than it should be!

I bought the phone today, but I think it's way slower than it should be. I know that the LG G Flex 2 has a Qualcomm Snapdragon 810 with 2.0 GHz quad core and a 1.5 Ghz quad core (octa core) CPU, but after i have runned a couple of benchmark tests in Antutu, I got a score between 35000 to 40000! That's way slower than Samsung Galaxy S5's Snapdragon 801! I thought that it whould get a score over 50000 When I see info about my CPU in Antutu after bemchmark test, it stands that the first four cores has a frequency of 1.5 GHz, while the other four cores has a frequency of 0.9 GHz (two of them are "sleeping" a lot)! Is it possible to fix that? I hope so. I've got the 16GB version with 2GB of DDR4 RAM. The device is upgraded to 5.1.1 Lollipop. (Sorry for bad English, I'm from Norway)

i got mine at Tuesday. I can pretty much say i never experienced a lag before even tho i had many apps in the recent apps tab and also i was playing high quality games and it got a little bit hot but still it was working flawless, very very fast. What i did after i updated to 5.1.1 i did a factory reset, then i downloaded only the apps that are indeed from lg apps such as calculator downloads quickremote (because most of them are useless and slow down the phone) and then i downloaded a custom launcher and greenify. Also use the google keyboard from google play store. better to use google's apps rather than lg's. Since then i never experianced any lag before. try it out. If u need more help tell me

That is really low. Go into settings and into battery saver and check if you maybe turned it on, and also see if you checked option to optimize battery in games.
Try restarting the phone and run antutu again, after a couple of minutes..
Sent from my LG-H955 using XDA Free mobile app

You are from a cold country so it should help. First try let rest the phone and launch antutu when it's at room temperature.
Then try with an ice pack on the back. It can be ice pack for injuries (kind of thick gel in plastic bag) or for cool box or ice chest, whatever you call it. But don't use it too long, you may have condensation inside the phone and it will trigger the humidity sticker (for your warranty).
Don't launch antutu after a reboot, as it's warm after a reboot. Or reboot and let it cool down first.

Can somebody explain what I have observed?

Hi fellow S6 users! It seems like that I can only get great 3d gaming performance on marshmallow by flashing space x kernel. Hacker, nog33k, twisted and even arter kernel lags on 3d games such as real racing 3 and modern combat versus.
Even at the same cpu and gpu frequency, all of those custom and even stock kernel lags on gaming but not while on space x kernel.
I have also observed that smooth gaming experience can also be found in ressurection remix by @macs18max. FWIW, Lineage os by team nexus on the other hand, is very choppy in 3d games.
Can somebody explain why is this so?
(Please do note that all of my tests were done after allowing the device to cool down so we can cross out thermal throttling here)

Very obvious answer. Samsung makes their devices slower purposly just to make you buy the next gen even tho the old models are more than enough capable. You only can overclock the GPU with Kernel Auditor or app of this kind. Also you can "Turn on 4x MSAA" option i develower options menu.

Planned obsolescense seems to be the right answer I'm afraid. But the thing is that why can spaceX kernel be smooth in gaming at stock clocks mind you as to compare to other custom kernels which lags horrendously in gaming whatever the clockspeed you set the gpu or cpu. This laggy behavior in games can also be observed in stock kernel of marshmallow or nougat. It seems like the only exception (aside from marshmallow with spaceX kernel) is Resurrection Remix Rom by @macs18max which have excellent gaming performance!

Search logcats in the system buffer with
"SIOP_ARM_MAX"
"limitGPUFreq"
"limitCPUFreq"
after the phone slows down.
Is this it? SIOP_ARM_MAX as the reason looks more like power saving (low frequency, exits slowly after cooling).
First could be filtered with logcat -b system -s CustomFrequencyManagerService, others are random letters.
Search /system/framework/oat/arm/services.odex , might have a list of package names that are throttled differently.
Edit: could be about power saving, or people complaining that the device is hot or warm, or to try to prevent USB failure, or to try to prevent eMMC failure, or to try to prevent battery failure. Maybe not planned obsolescence because it's on the S8 too (but the hardware is better).
Phones with marshmallow ROMs and above.

Question CPU core going offline!

Hello I have Poco x3 pro global version. I rooted my device and installed Kernel manager and there I saw CPU core control and I made some core offline and online again just randomly to check the performance difference. But there is an issue I am facing is when my device getting a little bit of heat the core 1(Little) and core 5(Big) getting offline. I used to check the CPU cores. After using Kernel manager for 6-7 days I had never seen any of the cores going offline. But recently I am facing the problem. So I thought it might be a Kernel or the app problem. So by not taking any risk I flashed stock miui 12.0.6 firmware and rooted it checked it again and the cores are still going offline no other cores only core 1 and core 5. Then I installed miui 12.5.9 eu and checked it out it still going offline. I know that CPU cores are online by default and when It gets hot it gears down the frequency but making cores offline Is a new experience. Did i gave a path to CPU to act abnormal by making some cores offline and online. Ohh when the they are getting offline significant amount of lag is being seen. Apps opening speed is pretty slow frame dropping in animations when opening apps. When my phone was not rooted I did face lag when heated up but not this much. Is it normal? Am I overseeing the fact. Please let me know I am

im also facing this problem, 1little and 1big core goes offline while gaming (ragnarok m)
using latest fkm on a crdroid 9.0,
i use this mainly to disable the sh*tty prime core....
any solution to this mate?

That's Called throttling,
Make super your phone become cooler. Problem solved.

Do not tinker with things you don't understand, people. Curiosity killed the cat.
