Thermothrotteling a performance killer on snapdragon N910F?

Hi,
I know that thermothrotteling is a feature to protect the cpu against damage. But what I notice that the temperature on my Note 910F is raising quire fast and that I am running into performance issue quite easily. Just playing arround the internet , watching something at youtube is bringing the device into the throtteling mode and than everthing is in slow motion (no hardcore games are neccessary). On my Note 3 I was never aware about such a situation.
Im using the Echoe rom 1.1 with the Ecoe kernel 3.5 (and fairly conservative power saving settings), but it is not kernel related because on stock it is the same.
Anybody facing a simelar situation?

Thats not normal :/ i guess sd being 28nm and clocked at 2.7ghz does generate some heat

Your not alone. That is the very reason why I rooted my phone yesterday. The Samsung DVFS is very aggressive on my note 4 with 4.4 kittkatt.
Iv noticed in benchmarks once my phone heats up a little it drops the GPU and CPU down to about half speed and im only getting half the score and in gaming after a few minutes I would start to notice a little lag and my cpu speed would be staying at 1297. It slowly drops down to that then stays around there.
I disabled the Samsung DVFS and use setcpu aswell to keep it at the full speed while gaming and it works great now and the temps are hardly any different.

Many thanks for the feedback.
I have switched off Touch boost und set Max cpu to 1.9GHz
Will see how it works.

It is quite annoying have such a fast phone but it downclocks both the cpu and gpu after a few mins of gaming.
A good test is GTA vice city with the settings cranked up.
With DVFS enabled once it hits about 56 degrees it starts to throttle and downclocks the gpu and cpu to about half and the game becomes a laggy mess.
With DVFS disabled its as smooth as butter but the temp goes up to about 70 degrees. Whats the max safe temp for this phone?

I do not know the safe setting.
I am using the echoe kernel and this kernel offers the “intellithermal“ feature from faux. You can set the temperatures when frequency throttling should start as well as kernel throttling. They give in the faux app also some recommendations.
Maybe you give out a try.
But I am disappointed because the throttling is affecting “normal“ life not only hard core gaming and this is for me somewhat a design fault.
At least on my Note 4 F
I never had this on my previous devices that I cannot watch a movie which is stored at my sd card. I have a number of tutorial and maintenance videos which are handy to watch on the device.

I can confirm this on the N910W8. As soon as the device heats up the frame rates drop dramatically. I also don't game. Just day to day usage. It's strange that some fairly simple tasks can heat things up so much.
I removed my ScanDisk 64GB Class 10 SD card which seemed to improve the heat problem.
Also, when its cool it smokes through GeekBench 3. After it heats up it runs slower then a Galaxy S3.

Just you my friend, I don't have that problem

Donkon....can you let me know what your idle phone cpu temp is? you can use the CpuTemp app and just let me know what it idles at on your homescreen and what it heats up to in a demanding game. Just make sure its the CPU temp and not the battery. thanks
It would be good to compare.

Also I was just doing some tests and these are my results.. im curious to know if these are normal temps.
My phone idles at around 34-38 degrees c.
With DVFS enabled it never goes above around 56 degrees as that's when it starts throttling down.
Iv never had any slowdowns in youtube or videos or anything like that. Its only gaming really and benchmarks where it starts to throttle once it heats up and in a game like gta it starts to lag abit once it throttles as it takes the gpu and cpu down to about half speed.
With DVFS disabled im able to run the full 2647 cpu speed when gaming and its as smooth as butter. My temp in riptide goes up to 58 degrees. In GTA vice city it goes up to around 70 degrees and in the unreal benchmark demo it goes up to about 74/75 degrees. Do these sound like normal temps when your running the full speed of the cpu?

Yeah, it is ok.
The Exynos start throttling at 80°C.

Which kernel are you using and what means “DVFS“?
Which app are you using for the kernel settings?
Best regards

Im using the stock Kernel. Iv only rooted. I haven't installed a custom rom or Kernel yet.
the DVFS is samsungs own voltage and frequency control program. Its what causes the aggressive thermal throttling in kittkatt 4.4. Its been there for along time but in 4.4 its pretty much too aggressive.
When you disable it the phone wont throttle back the GPU and CPU and a silly 56 degrees so it wont start to lag in games after a few minutes.

If anyone has GTA vice city or the epic citadel unreal demo can they run it and tell me what there CPU temp goes up to in those.. I just want to make sure mines normal as it gets very hot. With DVFS it should go up to about 55-60 and without it will be around 70.

Does anyone have freezes followed by restarts when disabling DVFS for just some apps (using blacklist)? I have this problem and disabling DVFS for the whole system really annoys me (opening app speed is slowed down + power saving mode requires a restart). I'm using the exynos C version.

Only 4 cores are used

Hello,
I have a peculiar problem with my OnePlus Two
The faster A57 cores don't get activated, I have tried using Antutu, played Asphalt 8 And NFS NL for hours.
But the cores just won't get triggered
I'm using A1 CPU tool to monitor the same.
Even CPU Z wouldn't show me any activity on the other 4 cores while Antutu was running.
Any ideas? It's brand new can be returned

I just installed A1 CPU to verify your issue.
It shows cores 0,1,2,3,4 are used at 1344ghz for me as well.
When i check with synapse (i'm on AK kernel) it shows all cores are used.
I guess it's a limitation with A1 CPU tool. Try with other tool that supports such architecure.

I was sceptical on the same but, out of the box I remembered seeing 1777 MHz frequencies.
Thanks a lot
I shall try more tools and get back.
Though I think if you're on a different kernel and had the A1 CPU tool been correct it would be redundant, Because core allocation would be done on kernel level (in my knowledge).

I know that it was already discussed but maybe someone has found a solution.
The problem is that performance of device gradually decreases proportionally to the level of the battery.
For example:
- battery is 90%, Real Racing 3 runs perfectly,
- battery is 45%, some lags appear during gameplay
- battery is 10%, heavily FPS drop, almost impossible to play
Battery saver is turned off, device is cold in all tests.
If I would like to save my battery level - I will turn on battery saver manually,
but I WANT to have good game experience not depending on battery level
This is really crazy.
Tested on stock OOS 2.1.1, with stock kernel, with Boeffla an AK, tested on Exodus ROM - everywhere I can see this weird behaviour.
May be some system files must be edited to overcame this issue?

Hi Jemcik, hi Denhot!
I'm facing the same issues on my new device and it's definately not normal!
With a battery level of 19% I was not able to get the 4 A57 cores online, which results in lower system performance. Have you found a solution?
@Denhot!
Maybe we should rename the thread into: IS OPT PERFORMANCE REALLY DEPENDENT ON BATTERY STATUS AND IS IT A ROM FEATURE OR AN ISSUE!?
I think, one of the kernel devs should be able to answer this question.

It looks like some system configuration files with kernels activation policy have to be edited,
but I haven't found yet which files exactly.

I've never experienced such a function!
CPU power depending on battery voltage!? 62k with full battery, 49k with 20% battery both with same CPU temps!
Hopefully not a general problem on our side with the motherboard Voltage Regulator or something.
Have you been to a kernel thread and asked this question? If not, I will ask this in AK's kernel thread. Maybe he knows more about it!

The 4 high performance cores will only be activated when needed. What app are you using to check the core usage? Every now and then you should see 2 of the high performance cores sometimes coming to life every now and then, with the other 4 power efficent cores being more busy. Use CPU-Z to check.
Due to the way Oxygen OS's stock kernel works, only 2 of the high performance cores will ever be active, alternating between the 4 cores in an attempt to keep the phone cool and not throttle as often. If you want all 4 high performance cores to be active as well as overclocking it back to its original speeds, you'll need to flash a custom kernel.

Hi,
would like to share I don't have a similar experience, with NFS NL or Asphalt, phone was consistent with no lags even when it got unbearable to hold.
I as playing and simultaneously screen mirroring over to a TV.
Going from 65 to 25% over a long course.
I normally won't let my battery fall below 20%.
So the thing about Li-ion/pro is that as you go lower voltage decreases so to provide same power draw current increases.
Basically it would heat up faster.
That can be a reason combined with that their might be inbuilt measures to save battery like you said, nor as an engineer I would recommend you to stress your phone at those levels.
I can't explain the lag at 45%, didn't find it might try real racing 3 later to check.

This is consistent with what I've noticed. The time It didn't, a simple reboot helped solve it and it hasn't occurred since.
Also these tools can't monitor the other cores, if you're rooted why not try synapse as helkat suggested

Thanks man!
I know how the S810 should work!
But I thought the performance issues have only to do with the temps. But now it seems it have also to do with the battery level.
It would be good if someone tries to reproduce the following to verify it:
1. One run Antutu benchmark with fully charged battery and room cool temps.
To be sure the conditions are the same, shut the display off for one or two minutes, than start display again, kill all recent apps and run Antutu test and note the results.
2. Than wait or do something until your battery is down to 20%, shut the display off for the same time, kill recent apps and start Antutu test run again and compare the results.
I've also tried the same after a reboot, with always the same results.
With 100% I get scores between 60 and 66k and with lower capacity (20%) I get only 48 till 50k!
I am not interested about the benchmark results, but I need to know if this only occurs on my side.

So, guys!
I have tested it the last few weeks and it is a fact that the performance in benchmarks is dependent by the battery level.
We have tested it with 3 devices and it is always the same.
But thank God, it seems on the devices perfomance themselves (in apps/ui) this has no effect!
But each one can replicate this behavior very easy!

I have the same issue! When battery level goes lower than 20%, my A57 kernels become offline. I checked this with CPU-Z and PerfMon. And this is the same on stock or custom kernel. Now I am using Boeffla kernel. The most frustrating is that my UI suffer from this. I have lot of lags in simple apps, such as calculator or some messengers.

Same issue here, there are threads in one plus forums.
I think the threashold level is at 40 % ?? They made this to keep the battery up. You can also see faster battery drop till the 40-30% mark then it is harder to kill the battery.
I am also dissapointed in this, maybe we can search the kernel sources ? Or is there a daemon app that triggers this?
I received the phone with 20%-30% battery, started an antutu knowing how powerfull 810 chip is, then boom 45k same as the previos phone i had with 801 chipset...i was like what the fxck....runing antutu again with full battery - 66k.

well i have run benchmark in back ground with few game and apps .. and checked with cpuz max that i have notice was around 50-60% cpu load still 2 off those a57 cores were off using this device for 2-3 days it always turns off 2 cores for me rest 6 is working most of the time :/ Even in battery saver mode .. i am not sure if this is a cpuz issue as i have not rooted my device yet so cant say properly ..
Also i face some freq. benchmark issue like in benchmark it scores around single core - 690 multicore - 2.6K .. and if i restarts device it scores normal - 1.1K and 4.5K .. i have no idea whats wrong with this :/

20% Battery Mark
The drop in performance at 20% Battery is standard behavior of the Rom and Stock Kernel. The Big Cluster (A57) is completly shut down to save Battery. If you dont want this you have to use a custom Kernel which is able to switch this Battery saving strategy off. Boeffla Kernel for example can do that.

Read http://www.anandtech.com/show/9828/the-oneplus-2-review/2.
They "optimized" the soc.....
No they just turned off some cores so there is no heat problem.
So I think this is my first and latest oneplus.

they've hit the mark! What the hell, i think they must be sued for false marketing. Its just like buying a car with 400 hp and those hp are only there when i'm parked or listen to music, if i'm on the highway or on the ridge the car has 100 hp...wtf :|

Calm down lol it's actually good on their part. Shutting down A57 cores on low battery is a good thing because the A53 cores use much lesser battery. If you're out on a trip and have 10% battery, with the A57 cores this will probably drain off within an hour of intermittent usage. When only the A53 cores are active, the battery life will increase greatly.
Companies design phones for average users, not just gamers. If you don't want this feature, root your phone, flash boeffla's kernel and disable the BCL Battery Driver. It's as simple as that

4 a57 cores are stopped in my oneplus 2

so i recently bought a oneplus 2 and after a few benchmark i was socked as i was getting only 2300 multicore and 700 single core in geek bench .
So i was looking for what causing it all that i have found 4 of those a57 cores are set to off by os even when battery is 80+ and temp is well . Then after a restart its all good 6 cores were working fine and had some good scores . Again after a day those 4 cores were off and same as low bench mark score .. in good battery conditions ..
while those cores are off . tried bench mark and multitask with games and stuff those are still off so i get low benchmark scores and stuff ..
Most of the time those core get turned off when phone is in ideal condition nothing going on actually and only by restart it fixed it self .. is this prob with op2 or my specific device issue :/

I have the same issue. It happens when I use Google Chrome or YouTube app.
I was on OOS 2.1.2 but I have upgraded to 2.2.0... with this I have been using Firefox...
I have not tested yet with this new version if the issue remains.

It might be a problem of the benchmark itself if it is using Chrome. Oneplus disables the a57 cores in Chrome because it will suck the battery dry if you let Chrome have all 8 cores.
In normal use you will never notice the difference but the benchmark scores will be low.

Ever thought about device temperature? When the OP2 gets hot it switches off the big cluster. So if you are doing 1 Benchmark after another your device gets hot. If you are playing games your device gets hot. Pretty normal behavior of the OP2. If you want to change anything about it i would recommend watching the Boeffla Kernel thread. Thermal Settings were discussed there and implemented in the Boeffla Kernel too. Give it a try.

well as i said earlier this was no issue with temp or battery .. as this happens when phone is in ideal mode .. just unlock device after some time or while listening to music and stuff all of a sudden it closes 4 cores and does not start them until i restart . i have notice this while bench marking first time i was getting low scores after a few check i realized that 4 57 cores were down . Then i restarted device and everything was ok .. again after few hour those cores were down for no specific reason .

Nexus 6P only uses A53 cores?? Too low benchmarks

As above.
Daily use is very good, everything is responsive and fast.
However, benchmarks are roughly 50-70% of what they are supposed to be.
I tried to post a screenshot of CPU Spy, previously reseted timers and then ran BasemarkOS and Geekbench. (can't because less of 10 posts )
I see in CPU Spy that Max CPU state is 1555 Mhz? That's the A53 cores, right?
Is this behaviour normal?

Are you on Android N?

So what is the best app to monitor cpu activity?
And why are my benchmarks so low?

Kernel Adiutor is a free kernel manager. I prefer using ElementalX Kernel Manager (paid app). Both work perfectly fine on Marshmallow, support HMP, and receive frequent updates.
If the phone is hot, then benchmarks will suffer. The big cluster gets throttled and goes offline whenever the temperature reaches a certain point. If it is running cool and you see low scores then idk cuz I don't do benchmarks.

If the phone is responsive and fast as you say why do benchmarks scores matter? Benchmarks are pointless, they give you a pretty useless set of numbers that don't equate to real world usage. If your real world usage is good (as you pointed out) then you're wasting time and energy worrying about something that doesn't matter.

I don't care about benchmarks, but they can point to a problem in your phone.
And I really would like to know how a phone sent to hardware testers consistently gets much higher benchmarks than the one I bought. Something's not right.

I've had eight of these and none of them have performed well in benchmarks. Take from that what you will but I believe it's a problem that's common to the SD810, not necessarily that you have a defective unit.

The phone is thermal throttling because the 810 Is overheating and the cores are being turned off. You can thank Qualcomm for their faulty overheating 810 design.

That still doesn't explain why phones sent to reviewers don't throttle so much...

sam here
I barely get my Bigger Cluster working
It's offline most of the time
I don;t mind the heat unless it doesn't damage my phone as I;m always using a cover
Any way I can change the throttle limits so that it throttles less?
will the CTT mod be good?

No traditional overclock by higher clock speed, just more power through higher voltages (and thus higher temps) i guess and maybe juice up and the gpu and ram for max performance.

I would guess that performance mode only changes CPU governor to keep all cores and frequency always active and available, avoiding the overhead of turn it on and off when needed.

Well afaik high performance only increases the brightness and the screen resolution.

I've been running performance mode the past couple weeks (set it to not change brightness) and haven't noticed any difference in battery. Still getting a full days battery and 6-7 hours SOT with LTE, GPS, Bluetooth on all the time and no wifi.
