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
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.

so this can be a issue with 2.1.2 .. and i dun have faulty device ! i don't know what triggers it as i face this for without any specific reasons like you had !
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.

tried many antutu and geekbench .. and tried with 2-3 games running in back ground and many other apps .. still those cores were down ! nothing turn those on ! other then restarting device .
Can you please tell me me to check it?

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 .
As we all know, the Snapdragon 810 processor in our OnePlus 2 phones is prone to overheat, especially during heavy tasks such as gaming. With the stock kernel (which probably most of you are using) this leads to the A57 cores being partially or fully shut down and the display - which generates additional heat - being dimmed in order for the phone to keep a healthy temperature (healthy for both its components and the hands that are holding it.) This, in turn, leads to lag when playing especially demanding games. Which in turn leads to a frustrated user.
With root access, it's possible to use custom kernels and/or custom thermal throttling profiles in order to (at least partially) circumvent these issues, by throttling the CPU frequency and/or limiting the number of active cores, using different schedulers and governors, and by applying thermal profiles that allow the phone to get hotter (in order to keep higher CPU frequencies for a longer duration).
Since I bought the OPT, I was playing a very power hungry game - Republique - which, at its highest graphics quality setting, pushes the phone to its limits. I quickly switched from the stock kernel to the Boeffla kernel and started experimenting with schedulers, governors, hotplugging settings, CPU/GPU frequencies and thermal profiles, but nothing I have done so far makes it possible to play the game for more than 15-20 minutes before some kind of throttling / heat control sets in and the game starts lagging.
I tried limiting both CPU clusters to only 2 cores while maintaining higher frequencies, I tried throttling the frequencies and keeping all 8 cores active, and I tried all kinds of solutions in-between with anything from 4-8 cores active and frequencies anywhere between 60% and 100%. I also tried the various thermal profiles that the kernel offers. But whatever I did, the game was either lagging right from the start, or running smoothly for about 15 minutes before the screen was dimmed and the CPU was throttled, leading to a laggy experience.
So my question is, what do you guys do to keep the OnePlus 2 from overheating during gaming, while at the same time maintaining a lag-free experience? I don't seem to get anywhere with anything I try, so I'd be extremely grateful for some useful input.

All the phones throttle while gaming. I use thermal extreme with boeffla kernel. And use 2 a53 at 1,3ghz and 2-4 a57 at 1,4ghz and I modified the throttle file and it underclock to 1,2ghz when it gets hot but it doesn't happen if you don't play longer than 30minutes and it doesn't lag either. You can leave stock settings but if course it will get hot quicker. Also with thermal hotplugged or something like that, I used it all cores online all the time at full speed and it doesn't throttle for a long time, so I don't know what overheating are you talking about. My nexus 5 throttle faster and disable 2 of 4 cores and leave the other 2 at half speed, and our processor overheats?. Oneplus throttle the device a lot because of the rumors, fortunately we can change that. Try what I said, cheers.

Thanks for the tip with thermal extreme! The implementation in the latest Boeffla kernel v1.1 beta1 seem to do a very good job of not letting the phone get too hot while at the same time not throttling the CPU too much. Today, the performance was stable for almost 30 minutes of gaming, and when I checked the CPU stats I saw that all cores were still active (2x A53 + 4x A57), and only throttled to 960 MHz. This still delivered enough performance. (I started the game with both CPU clusters at 1.2 GHz, so this also seemed to help with keeping the phone at an acceptable temperature. I'm sure it would've gotten much hotter much quicker at higher CPU frequencies.)
I have to admit though, I was playing inside in an unlit room and thus the screen wasn't at max. brightness. We'll see how it will perform during my next work break when I have to make the screen much brighter.

Does it throttle to 960mhz? for me never reach 1,2ghz. Playing real Racing for 30min it stays at 1,2ghz. And with thermal hotplugged (all cores enabled, all at stock freq gpu too) it doesnt throttle for 30 min, gpu only sometimes to 510mhz, i played 30 minutes and it didnt throttle, i dont know when it was going to throttle because i stop playing. But also, gaming with all cores and no throttling eats the battery.

I guess it throttled to 960 MHz because the game I'm currently playing (République) is pretty resource hungry.
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.

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

I am Noob to Android Development,,, I am having Oneplus 2 and installed Boefla kernel .. When i overclock my A57 cores to 2GHz my phone suddenly turn off and Turn on again after sometime... My question is Snapdragon 810 running on xperia z3+ has 2Ghz A57 ... So I am also want To Keep my phone stable at (A57=2.0 ghz ) .. i dont bother about Overheating or failure... I am Doing this at my Personal Risk.. So Please help me out
The 2 uses the 8994-V2 which is a lower binned chip than what some devices ship with so there is a slight variance in what frequencies and voltages chips can handle as with every CPU. These are not tested above their spec so you may very well have a dud. Another thing to keep in mind is that a higher voltage may help. Use 5mv increments until you no longer see the issue.
That's really it. That said, the 810 heats up enough. Over clocking will only add to that. Not to mention we are already seeing reports of cores dying and everything. So it really isn't something you should do.
