The device is great, after updating to unofficial CM12.1...
But, its kernel needs some work. The CPU generally stays in higher frequency (1209 to 800 or in deep sleep...) The lower frequencies are not used at all.. Also, all 4 cores stay active any time. Hence, we are getting heating issues and also less backup...
But, after updating to CM12.1, the audio quality is great. It has a true Wolfson audio chip.
how can ifix heating problem??

Hello,
I've a question regarding clockspeeds. Since yesterday i rooted my tab, as an early adaptor i experienced the lagging, heat failures etc. Since the JB update i've the feeling that the cpu doesn't run on max speed, also scaling the other cpu's is not as fast...
I downloaded several cpu monitoring apps, i found out my cpu never reaches 1.4Ghz. Max is 1,3Ghz, i don't know of thats for real or a bug in the monitoring code. But several apps have showed this, ex system tuner, also i found out that almost never the fourth cpu comes on. I'm not an excesif gamer, but for the test i played asphalt 7 and nfs shift.
Do you guys have an idea how to solve/tune? I already flashed the Vorbeth GPU OC (Thanks!:good but i wasn't able to find any more kernels or CPU mods.
To me its very very annoying that have a quad, but scaling very very conservative (I don't care about battery), i just want to ramp up and use all the cpu's hence i'm a multitasker.
Overall, i've the "feeling" that the heat issues are solved by using a very very conservative governer and not scaling max. Maybe i'm totally wrong, and i would be happy to hear that. Right now i feel kinda screwed.. by acer.
edit: Sorry for posting in general, i realize i've should post in QA
power saving level "balanced" is 1.3ghz, "High Performance" is 1.4ghz. It got introduced with an update. So your monitoring app is correct.
It could be possible to clock the A700 to 1.5ghz, but I wouldn't go higher since it's already getting hot enough on high CPU usage.

Thanks, however i've always turned high performance on. I forgot to mention, but aslo during testing.
What is overclocking?
Overclocking is the process of making a computer or component operate faster than the clock frequency specified by the manufacturer by modifying system parameters. One of the most important techniques is running at a higher clock rate (more clock cycles per second; hence the name "overclocking"), but other parameters, such as CPU multiplier and memory timings, can also be changed and would be considered to be overclocking. Operating voltages may also be changed (increased), which can increase the speed at which operation remains stable. Most overclocking techniques increase power consumption, generating more heat, which must be dispersed if the chip is to remain operational.
Advantage:
Higher performance in games, encoding, video editing applications, and system tasks at no additional expense, but with increased electrical power consumption. Overclocking can extend the useful life of older equipment. Adding noticible response time for multitasking and powerhungry applications and games.
Disadvantages:
Overclocking if it's not done with moderate rate can be very risky and potentialy might permanantly damage your device's hardware, plus it can cause a slight battery drain. If it's done correctly then you're good to proceed.
Undervolting :
Undervolting is reducing the voltage of a component, usually the processor, reducing the voltages of each step less than the original stock voltages.
Advantages:
Increase of Battery life.
The heat that come from the processor reduces.
Disadvantages:
Undervolting if it's applied correctly then it's good, Hard undervolting might make the device unstable and potentily will lead to bootloops and freezes.
CPU
Maximum clock that could be applied on The Galaxy S4 is XXXXmhz and the minimum is XXX mhz . I will add the stock clock values as soon as possible.
More to come asap !

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 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??

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
Hi, If you use yuphoria in a non-ac environment in India in summer where outside temperature is easily between 35-40 degree Celsius, your ear and nearby head area start hurting. Its a very dangerous, as it can cause permanent damage to ears or head.
Now before anyone say, common its a smartphone, it will heat up in such temperature, its normal, I would like to inform you, when I use my father's moto E3 power in same environment I don't feel any heat.
So obviously there is some problem with Yuphoria. consider this, your phone is sitting ideal from past one hours, a call comes, you pic the call, talk for 15 minutes and then you can feel that the screen is warm in the top right corner. you are not playing any game, doing nothing which involves heavy cpu processing, you are just taking a call for 15 minutes.
You should not feel any discomfort by doing this if mobile is Ok, as proved by moto E3 power. So something is seriously wrong with yuphoria.
So I tried to search the net to know the reason why yuphoria is overheating and came across useless advice, like stop the running processes , use different charger etc (I mean basic stuffs), but my question was still unanswered , why motoE3 power is cool even if other apps are running and yuphoria is not.
In my experiment I came across one very interesting observation which is not discussed anywhere, so here I am presenting the real cause of yuphoria's heating problem.
If we see the cpu usage using CPU-Z app in moto E3 power when no other application is running, we can find that its 201 MHz for single core most of the time. This I have checked in moto E3 power having stock ROM and data connection off. I am attaching here screenshot.
https://ibb.co/ddCmLF
If we do the same thing with Yuphoria , it never goes below 800 MHz. here are the screenshots of Yuphoria CPU usage and governors selected
https://ibb.co/bUJyZa
here is the governors
https://ibb.co/iCJXua
So obviously Yupohria CPU is always running at higher frequency than Moto E3power .
FURTHER MOTO E3 POWER HAS METAL PLATS ATTACHED TO PROCESSOR TO ACT AS HEAT SINK. you can check out the disassembling video of yuphoria and moto e3 power on youtube to see that moto e3 power has heat sink whereas yuphoria doesn't have it.
Moto E3 power is using mediatek processor which produces less heat and also the highest frequency of Moto E3 Power is less, still they included a heat sink in moto e3 power.
yuphoria is using more heat producing snapdragon 410 processor, still the engineers have not included heat sink. why yuphoria ? why?
I experimented by setting minimum cpu frequncy to 200 MHz and using powersave governor and found that now I can take calls without any heating issue. Remember still in this case yuphoria is using 3 cores with 200 Mhz frequency where as moto e3 power is using only one core with 201 MHz.
now I understand that moto E3 power is running on stock and my yuphoria is running on RR Rom, but I used to feel same heating problem even when my mobile was on original cyanogen ROM, so I think this problem of processor not going below 800 MHz is present even in original cyanogen ROM of yuphoria.
Now I want to know from all the technical experts here, why yuphoria's cpu is not going below 800 Mhz even when no other app is running. Is it the limitation of snapdragon 410 processor and nothing can be done about it, or it depends upon kernel and flashing another kernel or ROM will solve the issue.
obviously we don't want to use powersave governor with 200 MHz setting, otherwise what's the point of buying a 1.21 Ghz processor mobile. We want it to use minimum frequency that 200 single core when no other application is running and using higher frequency only when required like moto E3 power.
Is it possible? If yes , how?
I am also curious to know why they decided to not include heat sink in yuphoria?
I am not a technical expert but i don't think 800mhz might be a limitation of snapdragon 410.
Plus with ur experiment results i think it might be actually software flaw and with custom kernel or a custom rom which gives the ability to choose min and max speeds should fix it as u can choose min to 200mhz even with other governors.
So my Moto X Pure only gets around 5 hours SOT and around 2-3 hours playing games. I seen a 3200 mAh battery replacement on Amazon and I'm wondering if anyone has tried it? I'm using the Resurrection Remix OS with my CPU set to power save in the battery options. Please post your battery stats and ROM information so I can see if my phone would benefit from a battery change.

LoL... With your SOT and game times, your battery is holding up pretty well. I would not expect much of an increase from any battery replacement you may get.
Regarding batteries from Amazon, be wary-especially of those claiming more mAh. Typically higher mAh means a larger battery so be skeptical. Based on what I have read in forums and reviews, it seems many of the batteries for this phone from Amazon, regardless of advertised mAh, have been hit or miss. Some manage to do well for 3 to 6 months then problems start.

I lowered my GPU frequency to 300 MHz that seemed to help a lot especially when playing games my battery doesn't drain as fast. I even lowered my screen resolution to 720p and set my GPU frequency to 180 MHz. The OS is smooth but when I start playing some 3D games you can definitely notice FPS drop so I put it back at 300 MHz. I couldn't increase my battery by lowering my CPU frequency for some reason my battery life seems worse when I try to mess with the CPU. The only thing I managed to do was disable my big cores in kernel auditor when they aren't needed and setting my low memory killer to aggressive in kernel auditor seemed to help my battery as well. That's just my personal experience hopefully someone will get something out of it.

The CPU for the most part does pretty well scaling up and down based off processing needs. You probably just don't have CPU intensive apps so didn't notice much. You notice the GPU while playing games though. I think for the most part setting to a lower resolution might help with games at lower frequencies on the GPU in terms of maintaining higher fps at lower frequencies, but a 5.5 2K screen with simulated 720p probably doesn't net much battery life in other usage areas.

Right I am able to keep my GPU on power save and it'll sit on 180 MHz and the OS is still smooth on 720p if I bump it up to 1080p I'll have to put the frequency at 300 MHz or else it'll lag. I noticed when I move through the OS the GPU will jump to unnecessary frequencies like 300 MHz or even 450 MHz. Keeping it locked to 180 MHz while using Firefox or watching YouTube helped a little bit. The main problem for me is the lack of kernels to choose from. I used this tutorial https://forum.xda-developers.com/nexus-5x/general/guide-advanced-interactive-governor-t3269557 to tune my CPU governor since the Nexus 5X has the same SOC but my rom Remix OS has a feature called CPU boost that I can't turn off unless I flash another kernel. The problem with the Moto X Pure is that it doesn't have many custom kernels. I managed to find one that works with my rom but the camera doesn't work. I could simply go to another rom but they lack the customization Remix has and some of them have SeLinux set to permissive and I don't really feel like dealing with escalation attacks and having my bank information stolen.

Wow. Since I first got the phone 3 years ago, i personally just have had very little time to delve much into doing custom ROMs and kernels for this device due to work scheduling I'm moving to a new job this month and should have more time on my hands. I'm probably going to get back into things.

I'd compile a kernel for lineage based roms with the nougat modem but I'm not that smart I don't even have a computer to do it with lol.
So I went ahead and installed the EX Kernel Manager app and I downloaded the Hawktail governor profile. After doing that my battery went from 2-3 hours SOT to 4-6 SOT from 100%. When I play slither.io on the default CPU setup my battery would drop 10% every 10-15 minutes. With the Hawktail profile it drops 10% every 30-40 minutes. I thought this was incredible because NFC and Bluetooth was still on. I also found that the Alucard CPU governor gave me similar results during my observations. I really hope somebody else can benefit from this thread.
Here is the download link https://androidfilehost.com/?fid=24686679545610694
Remove the .txt extension and put it on your micro SD card or in the ElementalX folder. From the Ex Kernel Manager app go to CPU>Governor Options>Load then load the HawkTail file then click apply on boot.
