So since there is a thermal throttling problem going on with this device, that occurs during benchmarks, i was wondering if anyone has ever experienced performance dropping due to this throttling in real life usage (e.g. playing some performance-heavy games / using complex apps or whatever).
Just wondering, as I can't test this myself, because the phone isn't available anywhere.
I played Minecraft on my phone for about 2 hours the other day and didn't notice any performance drop off
NFS MW def drops frames.
custom kernels do help by setting the cpu low and then your manual edits on thermald conf to prevent too aggressive throttling on GPU.

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.

or you can run a custom kernel(like trinity) that disables the battery thermal throttle and not worry about it.

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.
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.
Is it safe to change my CPU governor to "performance" to force max clock speed?
I don't want to overclock my Note 4, don't worry, not talking about that. But I am talking about MAX clocking it - forcing it to run at maximum rated speed. I've already tested out SetCPU and used it to change my governor to performance which forces the clock to max, and it nearly doubled my framerate in many games, especially the ones that struggled to play on this device like Xcom:EW.
But I quickly turned it off because I wasn't sure it was safe to do in the new era of smartphones, what with their DVFS and all. I'm worried that I'm going to overheat the CPU, and it's not going to be able to downclock because of temperature anymore. I'm only modifying the governor, but what if I actually used SetCPU to just change the CPU clock to max, without even touching the governor?
Can I hurt my phone by doing this? Can I safely start forcing my CPU to run faster while playing games, knowing that the only thing I risk is my battery draining faster, or am I actually risking damaging components by doing this?
Hello and thank you for using Q/A,
your CPU will not be damaged, but the battery life time will be shorted.

I personally have used Performance governor on Moto X 2013 for almost the whole 8 months I had it, 24x7 I mean. Never had a problem, yeah maybe battery life was little less than normal but I never did really care about it. Then I ran the same governor for a good period of time on my Note 3 too, same, no problem at all. Like you said, in games the frame rate difference is massive, but I don't play much games, I simply used that governor because it gets rid off all those micro lags and jitters which are Android's trademark, I simply can't them, with default Interactive the micro lags are very apparent.
However with Note 4 I am pretty happy with the BluActive governor, it makes most of the micro lags to go away, so sticking with it.
In any case unless you plan to use a mobile phone for maybe 5 years or so, I don't see any problem at all with it, other than a slightly increased heat, and maybe a little less battery backup, but you will find so many comments which might scare you, that chip burns off if you run it and all that, but those mainly are BS.
So I got G6 yesterday and I liked it. but, after about 30-60 mins of gaming, the device starts to slow down
For example, I was playing PUBG at high settings at ~45 fps, but after some time , it drops to ~20 fps, extremely unplayable
Is there anyway to fix it??
I've heard that CPU Throttling is the problem, but I didnt find a way to disable it
I am using the LG H870DS Model
Then cool your Phone with something down, like playing under Water.
Of course its throttling down, cause of the Heat, LOL.
You were able to find XDA Forum and to login, so you cannot be stupid like that, not to know what thermal throttling means -.-

I am aware that thermal throttling was caused by excessive heat
If I am not mistaken, Thermal throttling is basically CPU and GPU underclocking automatically when reaching high temperature (50 celcius most of the time) to avoid potential hardware failure
But the problem is the throttling was so bad. compared to my other phone. But yeah I am aware that thermal throttling exist for a good reason
You play too much mobile Games, take a Computer and become Masterrace ?
NO LAG, CHOPPINES. PLAYING FOR FEW DAYS. APPLICABLE TO ALL SNAPDRAGON 810 DEVICES!
Update: Connect to charger if it lags. I've getting screen unresponsiveness after playing a few days without charging. Connecting to charger those lags are gone. Always try to play with mics and speakers off in game. Always cool your phone. It will feel burning otherwise.
Hi. I've seen lots of videos on YouTube, PUBG doesn't run properly and lags a lot on our device. Also its same on other snapdragon 810 devices. But its a high end chipset why should it lag? PUBG lags because of its throttling. But without throttling then burning heat.
Now do these:
I'm not responsible if anything bad happens.
1. Keep backup and delete thermal-config file, reboot.
2. Lower your CPU and GPU frequencies according to your game quality settings. Example: For Smooth and Medium FPS, set CPU to- big:960/633, little:1478mhz. or lower. GPU settings- 450/390 MHz. Check your settings and frequencies by yourself while playing.
You can disable CPU input boost if you feel.
3. Run A.C or Fan in your house, or play in much lower temperature.
4. Now run the game.
It won't lag, hang, and will run stable. But the device heats much. I tried even on HD at Ultra fps(GPU frequency didn't lower), the game ran perfectly and smoothly. though I lowered the CPU frequencies.
For HD and Ultra FPS:
1. CPU- big:1248(I tried and think enough, you may increase or decrease), little:1478.
2. GPU- I didn't lower GPU frequencies, it was running at 650, you may try 510 MHz.
3. Keep in mind to play in much lower temperature. Device will heat a lot. But won't lag a bit.
You can try. I'll update this thread sometimes.
Note: Always remind to paste thermal-config file in same directory and reboot, when you need. Also battery will drain faster in these. I tested it drains upto 27 percent per hour with throttled, and 29/30 percent without throttled on Smooth and Medium FPS with those settings.
*8*updated tested frequencies.
