[Q] inconsistent An tutu results............. - Nexus 4 Q&A, Help & Troubleshooting

Hi all.
Why is it that I'm plagued by inconsistent benchmark results?.
Same ROM, kernel, temp....results that vary by 3.5k wtf?.
I'm killing all apps & cache each time, even ended up reflashing kernels each time but no joy. Losing patience now : (
All i want is a rom/kernel combi that gives me consistant figures.

performance depends on various other attributes... like temperature etc.. ie if phone is hot it wont give good benchmarks due to thermal throttling... i guess that answers your question....

Why do you actually care about benchmark results? Surely this experience must prove to you that they're a wildly inaccurate indication of performance? Anyway, it could be to do with the thermal throttling especially if you do multiple runs of a benchmark in a row.
EDIT: Reread your post and saw you said that the temperature was kept the same throughout.

i bet its because you let it scale, plus other variances. when you benchmark, set the max cpu speed to be the same as the min. for example, 1512mhz highest cpu/1512mhz lowest cpu. also, your score wont be the exact same every time, itll vary slightly even if you do everything right(but not by 3.5k). and yes, heat. itll get hot and throttle, at different points of the test. you can disable throttling completely for better/consistent results.

Cheers to both of you guys.
I know that the figures are not too useful but was just initially using them to check if tweeks to kernrel etc have been +ve/-ve.
Also my biggest curiosity is about thetmal throttling. Now this seems to happen despite temps not reaching those set in kernel app.ie throttling set
to 70c yet performence being raped at 60°c

just because it might say 60C, it could have already reached 70C before the 60C was reported.

Cheers Simms.
I was leaving the max/min as they would be 'in real life' to simulate hie it would be on a day to day basis.
Im starting to think my n4 may be faulty then as the heat rises so damn quick despite lowering voltage by 100.
I keep getting excited by 21.5k results after flashing rom, then finding scores drop to 19/20 k : (
Initialy ELE, carbon & slimbean gave great results, then alas, no joy

by letting it scale, the phone chooses what cpu speed it wants to use, leading to inconsistancy. and the temp is going to rise that fast no matter whos n4 you are using. when i bench, i disable throttling and force my cpu to stay at one speed. thats how you get consistant results. undervolting wont help you at all with heat from benchmarking and can lower your scores.

Epic advice as always Simms. Much appreciated.
Golden question now is....how do I disable thermal throttling without crazy juju programming stuff.
I may have become a flashing junkie but know absolutely nothing about programming.
Is throttle disable available through kernel apps?, I have trinity & franko ones?

su(press enter)
echo N > /sys/module/msm_thermal/parameters/enabled(press enter)
running this script via a terminal emulator will disable throttling, or going to that location via root explorer and changing the Y to a N. this works woth trinity for sure, not sure about franco(it should work unless francisco changed the location. running this script with a Y instead of an N will turn on throttling again.

Ok so now I wen into franko app. Raised thermal throttle level to 100°c (surely phone can't hit that high so shouldn't throttle)
Flashed ziddeys otg franko (had 21.5k score before using this with slim), now just scored 18980
.ok I'm gonna delete an tutu and forget about it
Aldo set max/min the same.
Ok before I delete it I'll try that code thingy you added , cheers.

But phones start to throtle when battery temperature gets to 37°C and that overwrites your CPU throtling settings.
Example:
If you get to battery temperature 37°C the phone will start throtling even if the CPU temperature is less than 70°C.

i hit 100C the very first day i had my n4, lol. the rom also plays a role in your scores. bionic/krait optimized roms will score higher(22000-24000+). also, i wont run antutu until my cpu temp is below 30C or if im benching 1728mhz+ below 20C.

carbon should be, slim/liquid i dont know. and be careful about putting the phone in the fridge, it can cause condensation in the phone which can damage it. turning off the screen for a few minutes should be enough to cool it down, unless its really warm in your area.

Thanks for being patient with a noob. I'll reflash carbon.
Is there an easy way to tell if a ROM is krait optimised?

How high can I overclock

I can set it as high as 1646. IV looked around and it seems that people use 1504. Is it unsafe to go any higher?
Thanks
Sent from my A501 using XDA App
1400 is safest I run Alexandra iii
if you go up to 1.6 GHZ, you might get SHUTDOWNS...
if you don't run any games, or apps, sure it will work. But not smart to overload it.
If on Custm ROM, Read DEV Notes, usually they'll say (or mention about Kernel changing)
as a rule I keep it on 1.5 Ghz (when 1.6 was max) (have tested on about 8-10 diff roms) (never have had any shutdowns yet)
*** also maybe use a meter app to check TEMPS (like battery TEMP)
Cool Tool - shows battery temp, RAM, Proc Freq, + more in little box on screen all the time (adjust settings)
https://market.android.com/details?id=ds.cpuoverlay
"setCPU for Root users" - underclock to lowest when off, set lower cpu freq if battery gets warmed to ur custom Degrees)
http://www.setcpu.com/
***Some custom ROM's have thier own Freq CONTROLER app (that could clash with prog or have 2 progs do the same thing)
Like humans NO TWO CPU's are equal
All of the above it true with one exception..NOT every cpu is created equal Not all ram chips and so on also live up to this..
Start over clocking your cpu slowly. as you push clocks higher of course lower voltage. This keeps heat down .
Two processors even made on the same casting can be totally different . Where one will take more heat with less errors and corruption and the die next to it will almost crash running its designed clock speeds . Being that extreme is very rare with a few exceptions. most are close as to a common ability. within a few 100 mhz.
So the answer is there is NO TRUE Answer. its trial and error but on the side of caution and testing clock speeds and heat is not a 30 second yes it runs. Do it over a week or so. I know with my dragon cup in cell phone its at its end of life from being over clocked for a few years. some last longer some die quicker.. Its kinda like drinking on your brain the more you drink the more cells you kill.. The hotter your cpu gets the more transistors fail the slower it becomes the more errors you have .
Relax .. go slow.do not expect to get what everyone else is claiming. and you will be fine..
Sorry again for long winded post..

Any is unsafe. Higher speed equals heat and heat kills semiconductors. Might work for a while but why risk it
My daughters has been running at 1.6GHz for 2.5 months without any crashing or blowing up.
I say at 1.6, you're starting to enter the "red zone", sort of asking for problems. Why go up that high? I mean, 1.5 shows enough performance improvement over the 1GHz...

hot CPU (75 C)

According to the System Tuner app, my CPU went up to 75 degrees Celsius while I was playing a track on Google Earth. I was running Earth for only a few minutes before it reached 75. I'm not sure if that's the peak yet...maybe it can go even higher.
I've seen several other threads about heat, but most people talk about 50s and 60s. Anyone reach 75C? The front and back of the phone, the top around the camera, were both very hot. It was almost uncomfortable to touch.
Again, I'm talking about 75 Celsius, not Fahrenheit. And I'm referring to CPU temperature according to System Tuner app, not battery temp. Anyone reach this?
picture plz.
the reason is bc someone did a stress test on the N4 and found that the device shuts down at ~57-59C (correct me if im wrong) to prevent damage to the hardware.
Edit: found the link http://www.youtube.com/watch?feature=player_embedded&v=koLJ4BU9tgc
75ºC on a quad core?
I thought it was supposed to be more efficient than a dual core... 167ºF just seems like it's way hotter than any electronic device should ever be.
Sent from my SPH-D710 using xda premium
My first gaming laptop was an ASUS Republic of Game first generation. They did a horrible job cooling the machine. During the 2 months before the machine failed, the GPU would reaches 110 - 140 C if I played games (then, of course, the machine turned the GPU off and still ran as everything else was still about 70-80 C)
When the machine did fail, I opened it up, and found 2 fried thermal unit, a fried GPU and a nearly fried HDD) Amazingly, the machine stills runs, as long as I don't load GPU driver
Well, that's the story. Back to OP, as you see, if the temp is too high, you device can be literally fried. So if you turn off the thermal throttle, please enable it back on and do you best to keep your device cool
I tried to replicate just now and could only go up to 63c. I don't want to keep trying based on the comments here so far. If it happens again I'll be sure to get a screen shot and be aware of what's running.
Where would the thermal throttle toggle exist, if I have the capability at all? I'm running faux123 kernel and use trickster mod and trinity kernel tools for tweaking. I don't see anything about throttle control.
On a similar note, faux123 seems to default to 1ghz minimum cpu frequency. Does that seem right? I've flashed lots of kernels before on previous phones and they always default to the lowest value. When I force the setting down to 384mhz, it automatically changes back to 1024mhz the next time I go in my tool apps. Does this seem normal?

I haven't seen a Nexus 4 kernel that has thermal throttle toggle, or have it disabled yet. I am just checking if you're running one that I am not aware of

Minimum cpu frequency enforced by kernel is normal. I am not certain if faux123 default to 1 ghz min, but if it's the case, it seems weird for me too. Definitely not good for the battery. If there's no other CPU control apps, I recommend double check the settings, then find an update for faux123, or use trinity kernel
I just flashed a new kernel and my minimum cpu now seems more normal. I hopefully that alleviates the crazy temperatures too.
I'll try to test again tomorrow to see if my temps still go bonkers. It's time to sleep now. Thanks for the help, everyone.

[Q] Nexus 4 GPU Frame Rates Drops

Hello Guys, i registered to XDA developers to ask this question so please reply. i heard many say GPU of Nexus 4 is very bad because after 20 mins of gameplay the phone gets heated and the GPU performance is Dramatically Reduced to cooldown. I am going to buy Nexus 4 thats y im asking, i didnt hear this from my neighbours..., i saw someone say this in youtube comments. Anyone Experiencing this Issue? or its a defective product?.
This is a good thread to read about Thermal Throttling: http://forum.xda-developers.com/showthread.php?t=2144652
I am not sure about the GPU actually reducing it's power when the nexus is getting hot. I know the CPU will clock lower when it has reached 70 degrees so it can cool down. Most kernel's have the ability to up this to about 100 degrees so you won't have the thermal throttling as fast. You are also able to remove the throttling completely with a commando.
I've played alot of Dungeon Hunter 4/GTA Vice City/Real Racing 3 and I have never experienced severe FPS drops because of it getting hotter. The only thing you will experience is a battery that will be empty within 2 hours.
PS: This is based on what i've read on the forums, I do not have my nexus 4 for that long and I am not a developer, someone might be able to give you more accurate information.
The thermald.conf sets the battery threshold to about 40-41C before it begins to underclock aggressively (hence why it feels sluggish). I forget the exact number. It starts reading "Overheating" status when it reaches about 46C. Max rated temperature for the battery is 60C.
At that battery temperature ~41C, the CPU is no more than about 50C, so it's not the CPU overheating.
If you feel so inclined, you can modify the thermald.conf with root to modify how aggressive the thermal throttling acts, within reason. Otherwise you'll cook your phone.

YMMV with that. My nominal binned SoC overheats really easily. With the way I use my phone, it'd be overheating way too often.
I modified my thermald.conf so it's less aggressive. It's not that hard to figure out.
The phone throttles its clock speed like a PC. It's not a big deal.

[Q] How to tweak this kernel?

How to tweak this kernel for stopping G2 from overheating? Even I lowered my CPU to 1ghz it is still overheating. :crying: please help. thanks
Hi,
What is exactly overheating for you???
Can you share your CPU/battery temperatures?
Overheating... But when? When playing a game while downloading a huge file over 4G and while charging?
viking37 said:
Hi,
Guys you realize that you have a quadcore at 2.26 Ghz... And when you play a (heavy) game or some other heavy tasks (browsing in 4G for example) it's normal that the CPU heats, right?
Temperature is very subjective without reading the CPU temp with an app, it feels hot in your hand (you can have cold hands and in this case you feel much more the heat) and it's hot because the CPU temp is about 90°C is different...
Heat and overheat (or "maximum overheating" like above ) is different too..., in any case there is a thermal throttling that prevent overheating. Our CPU shutdowns at 120°C so there is a little room... Even 80°C is nothing for the CPU...
Even 90°C for the CPU temperature is almost nothing (for the the stressed people) and there is a thermal protection in any case. Thermal throttling that reduces the CPU freq according to the CPU temp, same thing for the battery. And in case of extreme temperature -> shutdown.
And if you speak about "overheating" when playing a game or browsing while charging your phone...
Check your CPU temp with an app and report here...
It remembers me all the threads about "overheating" in the Nexus 4 forum...

After that you can try to undervolt a little (be carefull, step by step and don't set your undervolt at boot unless you're sure it's stable) and play with the thermal control by decreasing the max CPU temperature before thermal throttling...
You can use an app like Trickster Mod or Faux123 app (kernel enhancement) on the Play Store.

After playing heavy games, I can use my phone to iron clothes. lol. Well, I know it have quad core that's why I bought it. And I think having this kind of power is a disadvantage too because it heats very quickly like 10mins of heavy gaming.. And by heating it decreases the battery life.. I don't want to use this quad core phone in just browsing and watching video only, i bought this for gaming also.. lol
I don't know now where to use these quad cores.. lol... I envy my brother now, playing games smoothly on his ip5s with cool temp.. >.<
I have fauxclock and leave it to Intellithermal frequency throttle temp:80c and core throttle temp 85c. Is that ok?
Thanks :cyclops:
Re,
Hummm..... :laugh:
Decrease the two temperatures of 10°C... And use Ondemand or Interactive governor with MpDesicion "on"...
Try undervolt/underclock a little... No need to underclock at 1 Ghz otherwise, right, it will lag...
But I don't think you really understand what I was trying to say... Heavy games+quadcore 2,26 Ghz+10 mins of use with that...= heat (and not overheating), are you sure there is something wrong or abnormal?
What is your CPU/battery temperatures???
And please don't compare our CPU's with the one in the Iphhone 5, it's not the same thing.

Begin with -25 mV but don't set at boot, use your phone for a day like as always (games, browsing, etc...). If you don't have reboots or anything wrong then try another step by - 25 mV. If you went too low your phone will reboot, (so don't use the set/apply on boot setting or you could have a bootloop), at this point you"ll know the undervolt possibility. Apply your last setting before the crash and see...
I don't know what we could do more... I think you need to read a bit more

Heloo i have the same problem when i play games likeplants vs zombies my phone hetas badly imen like 70°C(160°F) and i dont think it normal in like 10 to 15 min to be like that,i have root andtrickster app instaled and i alawys check the temperature.
I know its normal for the phone to heat but not so fast i seen thrads where users reported theyre g2 doesent heat bad att all.I have cpu threshold. on ,activated it from secret men.
So please helpwith advice and youre experience with this problem.
Thank you!
Hi,
Strif3, it's normal, point. 70°C is the CPU temperature limit before thermal throttling. What can I say more??? Read my posts above...
Use your phone like you want, as usual in any case there is a thermal protection! I think that Qualcomm knows how their SoC needs to be set about thermal stuff and I think (I'm sure) you can play heavy games without any issues even if your phone is at 70°C.
If your CPU temp was at 100°C (without modifie the thermal throttling), ok maybe here there is a problem (it depends also what you are doing), but I repeat 70°C during a game and after 10 mins i's totally normal!
If you all guys are worried about the CPU temperature, stop playing games, browsing in 4G and underclock your CPU to 300 Mhz and all will be fine...

Yup I also play that game? Why?

maybe guys you can help me also on undervolting d802 for gaming?
thanks

That game is known to be a battery major drainer and heat producer.

Aha i understand i must mention the cpu frequency at 70°C is like 1Ghz but no loss in performance and in browsing,music and youtube no heating problems.Just wanted to know its not a issue with my phone.
Thnx for info

le 2 ( snapdragon varient) performance issues

Devs,
The performance of le 2 is very bad when it comes to gaming.
It is the same in every stock eui to miui and all lineage os ROMs like AICP which uses lineage is kernel.
As per my finding this is due to severe thermal throttling in eui as well as in lineage os 13 and 14.1.
Firstly the two A72 CORES don't run while any task making it like SD 650 and clock go soo down at reaching 34° to 35°c and at above temp all A72 CORES ARE DOWN in lineage is and only one works in stock eui, same goes with GPU under clocking starts at 32°c making gaming experience horrible,
Even kernel auditor don't have any control in any of the ROMs and in lineage is 14.1 27 Feb build it is told it have core control but it can make all A72 cores run couldn't control clock speeds and result is the same ,
So I request devs please make a kernel from scrap and don't take hints from eui kernel and give us good gaming experience.
Thank you

My findings were exactly same as yours, the cpu and gpu, both are underclocking for even slightest of temperature rise. This is bad, but the good news is, I figured out a way, by which we can disable this poorly configured thermal throtling.
Delete this file here: /system/etc/thermal-engine-s2.conf
I don't know it it is safe or not, but I have been gaming with my device after deleting this file for about 10 days and there is no explosions yet. Hahaha.
Also, if you want, instead of deleting this file, you can modify some parameters so that, it starts throttling after some really high temperatures, instead of current values, but I like deleting that file because some thermal throtlling algorthm is always embedded in soc anyways.

See your findings are correct but I myself renamed thermal config s2 but it didnot have any effect and at 33 ° I can see GPU under clocked at 432 MHz and CPU under clocks itself , and at 35° the lagging in games can be seen easily
Will try deleting the file also ,hoping it can have any effect

My cpu temp have gone over 60°c but I haven't seen any throttling in cpu or gpu. But when, that file was present, those temperatures were never reached because of thermal throttling.

Deleting this file is an absolutely terrible idea. Modify it instead.

At first, I thought the same. But yesterday, i have played asphalt 8 in bright sunlight(to test if there is some thermal throttling left embedded in soc). And I was right, it throttles down the gpu, big cores, small cores, even some cores went offline automatically. After the device was cooled, everything wqs back to normal. So, IMO, there is no harm even if we play in extreme conditions with the file deleted, thermal throttling will kick in when its needed. Although, I advise modifying the file to others. Hahaha

Thermal throttling happens even in the best chips. Most of the time, it's integrated in the lower level portions of the chip.
Just let it be, really. Thermal throttling is the way of the chip of protecting itself from heat damage. PC processors, for example, shut down when removing the fan and reaching critical temperatures.

Ya true it is present in every chip but optimizing is Also a thing right.
In le 2 the two A72 cores don't run at all above 30°(except when opening apps while it is cool ,so after 33 or 34° they are not used in anything,and 34 is average temp of the phone while using ,that means it just exactly works like a loweclocked SD 650 which even more throttled with each degree rise in temp and at 36 ° ( which is avg temperature while gaming ) phone turns off one more A72 core meaning three A72 cores are off and one a72 is throttle to around 800 mhz and even all a53 cores run at half clock speeds and till that time GPU also reaches below 350mhz and lower a and it impossible to run even minor games like subway surfers lag free,
And since lineage is kernel has taken hint from eui kernel ,it performs exactly the same as stock kernel which leaves us with no choice left.
 @codeworkx please look into this issue and please build a kernel for gaming performance as SD 652 is getting wasted due to thermal throttling, @codeworkx I am sure you know this issue better than me ,please find time to work on it.
@shivamg95 deleting the thermal file couldn't help this

Deleting that thermal engine file, did help. Don't know why it doesn't work for you.

It is not working and would have been not working for you also just check with kernel auditor,
I have check it thoroughly .
I think you don't know how to check
Tell me the process you check

First i make the soc heat by playing games or running benchmarks, then i open kernel auiditor and check if maximum cpu freq gets lowered or automatically or not. But it doesn't happen after deleting that file. Also, the gameplay seems very fluid then before. I also check for gpu max freq.
Hey, I have Cool 1 (same Soc) and yes, very dissapointed because in second 1 starts the throtling...
I have Kernel auditor. Which settings should I force?
hello, very nice threat.
I had some different experiences.
For me throotling starts slightly at 37° and bigger at 39 or 40 ... this results to throotled big cores at 1248mhz and a gpu to 432
to avoid that I made some underclocking settings which gives my setting antutu score of 69000 instead of 82000 and a geekbench score of 1000/3500 which is giving me cool and fast gaming enough
