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.
I have been doing some heavy gaming on my G5 while monitoring the temps, and to my utter amazement G5 never goes beyond 40C mark even after an hour of continuous gaming. Because of that it never throttles down and stays at max cores almost the whole time. Now, coming from G3 this is a HUGE improvement where normal temps would go beyond 80C and throttling would make gaming virtually unplayable (even after root and thermal tweaks)
Sample temps comparison after at least 30min of continuous gaming (room temp around 23C)
Lara Croft GO - Max settings
G3= 80C+ lag and throttling
G5=36C+ smooth
Xenowerk - Max settings
G3= 80C+ lag and throttling
G5=35C+ smooth
GTA San Andreas = Max settings
G3= UNPLAYABLE
G5=39C+ smooth (yes I cannot believe it finally runs like butter )
Dawn of Titans = Max settings
G3= 80C+ lag and throttling
G5=41C+ smooth
Real Racing 3 = Max Settings
G3= 75C+ smooth
G5=31C Lag
There you have it, overall a whole 45+ difference in temps while gaming !!! Not only do games run buttery smooth, the phone stay cool as a cucumber.
The only exception here is Real Racing 3, which I think needs to be patched to work properly on newer hardware (even S7 SD820 has similar performance issues)
This goes to show that Qualcomm have done a miracle with SD820 and kudos to LG as well for proper hardware implementation.
Let me know what you guys think and if you want me to do more comparisons like this
i hereby confirm the temps and add temple run 2 (both maps, runs like butter in the mines), asphalt 8 aswell as modern combat 4 and 5 to the list of low temp max settings games.
even antutu keeps it cool
I can use Autoguard dashcam software with GPS enabled, waze in the background, and charge my phone and it's only slightly warm.
What is the best battery rom and your best SOT?
in my experience ; the best battery rom is eui 5.8.019s
I tested miui and battery was very correct in my opinion.
small eui v3 beta its good at the moment.

5-5.30. Gaming, social media etc
I am currently using Miui 10 pro global V8.9.20 + Illusion kernel V3 which is giving me 5:30 hrs of screen on time completely bugless.
You can get the Illusion kernel only in the Le 2 Telegram channel posting link for the same you go & download kernel from there.
1. Le 2 telegram channel link for Kernel
https://t.me/LeEco_Le2 (click this link in your phone after installing telegram make an account , use Chrome or Opera browser only other browser don't redirect this link).
2. Miui 10 pro Global for Le 2 link Gdrive
https://drive.google.com/file/d/1gbspIBvM3EhBeapluGfZl-UECNB_fEeQ/view
Cannot get illusion kernel.
URL leads to error 500.
Could you share another link please ?
Thanks

I have never got this much screen on time on the leeco le 2 (SD version) so I just had to share this with somebody... anybody really. Whomever has done better please feel free to share your awesome le 2 battery life with smallEUI, stock,or any other rom (doubtful).
So I just got 8 hours and 30 minutes of sot running smallEUI version 3 with illusion kernel v2.5. (Note: I used v2.5 because v3 uses lazy plug for CPU hot plugging which IMHO has far more battery drain than the stock Qualcomm core control) but I digress...
Anyways, I am a heavy gamer and frequently play real racing 3 for more than 1.5 hours in some days Today I decided to cut back and only played it for 25 minutes.This reduced gaming time enabled me to subject my phone to a more mixed use pattern. When I started I wasn't even looking to break any screen on time records but at around 21% battery remaining, I was at 7 hours SOT so I decided to keep using the phone normally until I ran it down to empty.
Here's some background to this achievement...
First off, I don't run anything on stock settings. I use a slimmed down EUI rom, a custom kernel to boot, and minor tweaks to the build.prop. I have done major tweaks to the custom kernel, use greenify in elevated mode, and block the recommended wakelocks on kernel adiutor app. I have also improved thermal thresholds to minimize throttling. When CPU thermal throttles, it leads to more power consumption because it has to stay on longer and use more CPU cycles to finish tasks that it could have completed much faster with high clock speed at the expense of negligible heating. I looked at the stock smallEUI thermal config and was shocked to find that the CPU starts throttling when it reaches temperatures as low as 38 degrees Celsius. (That's too low). The big cores are allowed to hot plug at a measly 40 degrees and at 42 degrees the system is allowed to turn off three of them. Only CPU 4, which is the first big core that controls the other 3 is exempted from being turned off due to this insanely low threshold. However, it doesn't escape the overall thermal tolerance which is set at 38-70 degrees. At which point, it will be doing just 883MHz before getting completely shut down! We all know (I hope we do) that big cores are generally more efficient at higher clock speed but someone must have missed the memo here. (Big cores are set to throttle down to 998MHz at just 50 degrees! Crazy, right). @iaureeel should look into this.
For monitoring, I use better battery stats xda edition, gsam battery monitor, and kernel adiutor overview page. I don't have WiFi so all data comes through 4G (the signal is usually above average to excellent) -- this phone has better reception than any other I've ever used ??
The usage:
Here's a summary of the notable things I did. You may browse the screenshots to see more.
First off: Games...
I played real racing 3 for around 25 minutes
Tried out a newly downloaded (on this same charge cycle) 3D game called war wings -- Around 20 minutes. Spoiler alert: it's awesome?
Starting with full charge and hammering the battery to about 15%, I can play real racing 3 for 4 hours non-stop.
Others:
I watched some YouTube over 4G for 30 minutes
I used brave to browse the web for just over an hour.
Side note: surface flinger showed up on BBS probably because I speeded up scrolling in build.prop. It shouldn't be this active but the power draw is probably not too significant.
How I did it
Recap of what enabled me to have this sot figure:
1. Optimized custom EUI-based ROM (smallEUI)
2. Custom kernel (heavily customizable and tweaked to kingdom come)
3. Greenify
4. Higher thermal tolerance for the CPU (it doesn't even get hot enough to be uncomfortable even at highest load. The plus for the battery here is that the CPU completes tasks much faster and then goes into a quick race to idle (thanks to a tweak I've added to blu_active governor for big cores)
5. No automatic brightness! I often get by with minimum brightness but when I need more I manually bump it up to 10-25%. 50 % is enough for me to comfortably use the phone outside. And not in direct sunlight because who can compete with the sun? Not any phone's display. THAT'S FOR SURE!
6. Cherry-picked build.prop tweaks
7. No Facebook, Instagram, Snapchat, and other naughty social apps that put your phone in a wakelock chockhold until its precious juice is depleted.
Conclusion:
I have never been one to hunt screen-on-time records (and wasn't in this case) but today has showed me a side of this phone that I didn't know existed. That's really good battery backup. I didn't think it was this easy but leeco did some clever things too in order to make it possible. First is charging the battery to 4.4 volts which increases charge holding capacity to 110% of the reference design. I don't recommend that you charge to 100% because it will be at the expense of battery life span. (Unless leeco uses a military grade battery like they do in the Coolpad cool 1 dual and LeRee le 3).
Another thing that helps is the inclination of EUI towards power saving. SmallEUI is even better because it saves power without hindering user experience. Notifications come on time and there is no stuttering even on stock everything.
Full disclosure: My phone is brand new(ish) at just one month old.
That's all for now... Check out the screenshots. As they say, the proof is in the pudding ?. There's a limit to the number of files I can attach so I've put the rest in a .zip file

I don't recommend that you charge to 100% because it will be at the expense of battery life span. (Unless leeco uses a military grade battery like they do in the Coolpad cool 1 dual and LeRee le 3).
Another thing that helps is the inclination of EUI towards power saving. SmallEUI is even better because it saves power without hindering user experience. Notifications come on time and there is no stuttering even on stock everything.
Full disclosure: My phone is brand new(ish) at just one month old.
That's all for now... Check out the screenshots. As they say, the proof is in the pudding ?. There's a limit to the number of files I can attach so I've put the rest in a .zip file

Hi. Good day, please how can you help me? I just bought this but it is consuming battery. So I decided to check online for solutions and I found this site. please help me I don't know so much about phone, I just want to enjoy the phone without having to worry about the battery or the high temperature (hot) problem. Thanks.

I have never got this much screen on time on the leeco le 2 (SD version) so I just had to share this with somebody... anybody really. Whomever has done better please feel free to share your awesome le 2 battery life with smallEUI, stock,or any other rom (doubtful).
So I just got 8 hours and 30 minutes of sot running smallEUI version 3 with illusion kernel v2.5. (Note: I used v2.5 because v3 uses lazy plug for CPU hot plugging which IMHO has far more battery drain than the stock Qualcomm core control) but I digress...
Anyways, I am a heavy gamer and frequently play real racing 3 for more than 1.5 hours in some days Today I decided to cut back and only played it for 25 minutes.This reduced gaming time enabled me to subject my phone to a more mixed use pattern. When I started I wasn't even looking to break any screen on time records but at around 21% battery remaining, I was at 7 hours SOT so I decided to keep using the phone normally until I ran it down to empty.
Here's some background to this achievement...
First off, I don't run anything on stock settings. I use a slimmed down EUI rom, a custom kernel to boot, and minor tweaks to the build.prop. I have done major tweaks to the custom kernel, use greenify in elevated mode, and block the recommended wakelocks on kernel adiutor app. I have also improved thermal thresholds to minimize throttling. When CPU thermal throttles, it leads to more power consumption because it has to stay on longer and use more CPU cycles to finish tasks that it could have completed much faster with high clock speed at the expense of negligible heating. I looked at the stock smallEUI thermal config and was shocked to find that the CPU starts throttling when it reaches temperatures as low as 38 degrees Celsius. (That's too low). The big cores are allowed to hot plug at a measly 40 degrees and at 42 degrees the system is allowed to turn off three of them. Only CPU 4, which is the first big core that controls the other 3 is exempted from being turned off due to this insanely low threshold. However, it doesn't escape the overall thermal tolerance which is set at 38-70 degrees. At which point, it will be doing just 883MHz before getting completely shut down! We all know (I hope we do) that big cores are generally more efficient at higher clock speed but someone must have missed the memo here. (Big cores are set to throttle down to 998MHz at just 50 degrees! Crazy, right). @iaureeel should look into this.
For monitoring, I use better battery stats xda edition, gsam battery monitor, and kernel adiutor overview page. I don't have WiFi so all data comes through 4G (the signal is usually above average to excellent) -- this phone has better reception than any other I've ever used ??
The usage:
Here's a summary of the notable things I did. You may browse the screenshots to see more.
First off: Games...
I played real racing 3 for around 25 minutes
Tried out a newly downloaded (on this same charge cycle) 3D game called war wings -- Around 20 minutes. Spoiler alert: it's awesome?
Starting with full charge and hammering the battery to about 15%, I can play real racing 3 for 4 hours non-stop.
Others:
I watched some YouTube over 4G for 30 minutes
I used brave to browse the web for just over an hour.
Side note: surface flinger showed up on BBS probably because I speeded up scrolling in build.prop. It shouldn't be this active but the power draw is probably not too significant.
How I did it
Recap of what enabled me to have this sot figure:
1. Optimized custom EUI-based ROM (smallEUI)
2. Custom kernel (heavily customizable and tweaked to kingdom come)
3. Greenify
4. Higher thermal tolerance for the CPU (it doesn't even get hot enough to be uncomfortable even at highest load. The plus for the battery here is that the CPU completes tasks much faster and then goes into a quick race to idle (thanks to a tweak I've added to blu_active governor for big cores)
5. No automatic brightness! I often get by with minimum brightness but when I need more I manually bump it up to 10-25%. 50 % is enough for me to comfortably use the phone outside. And not in direct sunlight because who can compete with the sun? Not any phone's display. THAT'S FOR SURE!
6. Cherry-picked build.prop tweaks
7. No Facebook, Instagram, Snapchat, and other naughty social apps that put your phone in a wakelock chockhold until its precious juice is depleted.
Conclusion:
I have never been one to hunt screen-on-time records (and wasn't in this case) but today has showed me a side of this phone that I didn't know existed. That's really good battery backup. I didn't think it was this easy but leeco did some clever things too in order to make it possible. First is charging the battery to 4.4 volts which increases charge holding capacity to 110% of the reference design. I don't recommend that you charge to 100% because it will be at the expense of battery life span. (Unless leeco uses a military grade battery like they do in the Coolpad cool 1 dual and LeRee le 3).
Another thing that helps is the inclination of EUI towards power saving. SmallEUI is even better because it saves power without hindering user experience. Notifications come on time and there is no stuttering even on stock everything.

I have THE Answering for You and ALL other Le Membershipper`s...
If you have a Smartphone, You have to CHANGE your Battery between 12 to 18 Month`s. If you are working in Office and you Use the whole Day Wireless Lan? Then, you have to change the Battery between 12 Month`s and every Year behing the change!
And Dubble 3M Band for the Displayframe you have to Buy also. Oh, IF, you want to Change your Battery then you NEED a HOT Gun Pistol with Minimum 110 Degrees! Heat Up the Frameside about 5-10 Millimeters and DON`T Lift it UP in the Roundings of the Edges! They are Breaking!!
While playing some games I noticed my phone(N910H/Exynos) has a very hard time keeping framerates once it heats up, I downloaded 3D mark and a frequency/temp monitor app and discovered that during Physics test my phone throttles at 92°C and keeps frequency at 1500MHz(simply can't sustain the 1900 supposed max) to prevent burning, how can the CPU reach 90° while my hands are barely any hot?. Then I watched some disassembly videos and turns out theres no thermal pad/paste between the CPU and "heatsink"(these older phones don't really cared for cooling,it sinks heat to the frame).I re-did the benchmark while applying slight pressure over the CPU area and my physics score went from 1500 to 1600, still reaching 90°C but taking a little bit more time to do so, so it kept 1900MHz for longer.
So I though about doing the experiment of applying thermal paste over the CPU, but i'm scared I may brake the phone on the disassembly, so I'd like to ask if someone is willing to do the test to see if it's worth it. Maybe we can unlock gaming potential we didn't know was there, thank you guys.
[Update] So I did the test
TL;DR: There's already a thermal pad there, so it's not like the results are shocking, it does make a difference but it's not worth disassembling your phone just for it.
BUT there's an additional experiment I'm gonna make sooo things could change.
WARNING: if you're thinking of disassembling your phone for any reason be warned that the spen digitizer connector is a little bit hard to connect so it happens pretty often that it won't work, so test the spen before reassembling everything.
Long version:
Anan did not publish the OC kernel yet but I was too curious and did the thing anyway, you don't need to remove the screen from the mainframe so the procedure is not really that risky.
Turns out that pinky thing I saw on the images are thermal pads (as anyone not stupid as me would already know), not copper as I originally thought, anyway since thermal pads are worse than thermal paste(even the 2w/mk ****ty one I used) I did replace it, I had to use a generous amount to make contact, after all it's replacing a thermal pad(0,5mm i think).
Overall CPU temps got like 5-10°C lower, but the benchmark results are pretty boring since they don't thermal throttle the CPU much, geekbench got 100-200 average more on multi core (no difference on single core) and antutu went from 99251 to 103408 ,CPU multi-score went from 26136 to 27971. The stress test basically achieves the same temps, only taking a few seconds more to throttle.
However,gaming performance did get a considerable boost,since they offer a constant heat output. Minecraft( yes it thermal throttles the cpu a lot) almost doesn't see throttles anymore granting a SIGNIFCANT better performance, Free fire also does perform better but stupid me did not pay attention to temps before the mod.
Heat on the phone also feels WAY less concentrated on the CPU area.
Now if you know a little bit about this stuff you know that thermal pads are usually used when the heat source is not touching the heatsink, which is the case here. I am 100% sure the results would not be this boring if the CPU actually touched the midframe, so I'm going to do another test sometime putting a 0,5 mm copper pad(401 W/mK vs the 2 from my thermal paste) to see the actual result I was expecting.
I know all this sound pretty stupid and pointless but I'm going to use this phone for another year or two so I want to make the most of it, also I really like this stuff.
If you want to know WTF is even going on you can watch this video/read the article: https://www.gamersnexus.net/guides/2137-thermalpaste-types-conductivity-and-more
I think someone has already done that, don't recall the thread
Use a kernel which can give you possibility to tweak. Search on Exynos forum.

A custom kernel would not solve this problem, as you need to get heat away from the cpu so it can maintain high power usage and low temps.
The only way a custom kernel would help the cpu run cooler is trough undervolting or increasing temperature limit, the latter is obviously dumb, about undervolting I have already tried managing mere -50mV wich did not change a thing.
So Anan confirmed he's porting Helios Kernel V3 to the lineage 15.1 rom (wich is the one I'm using) then well be able to overclock to 1500/2100. Once he posts that I'll see just how hard this phone throttles and then maybe do the procedure myself.
I got :
99251 on Antutu
1114 single 3734 multi core on geekbench
It throttles in both
the stress test in Antutu gets it so hot Im not really confortable letting it finish, it imediately reaches 90°C, keeps oscilating between 900 and 1900 on the big cores,in 5 minutes the entire phone is burning hot.
