Got My N5 today, its awesome,
Looks like the performance is so so, the phone heats up too quickly and CPU performance goes down,
If I do Antutu when its warm I get less than 20K in it
If I let it rest for some time and then do it I get a score of 25+
Looks like the device has heat issues
are you guys facing the same issues?
Two-part solution: Stop running benchmark tests and flash Franco kernel.
And, search before you post. Lots of threads on performance benchmarks
I see so many people who care what a benchmark score is.

its not a heat issue. it will get hot with use, especially with antutu benchmark, its a 2.3ghz quad core phone without an active cooling system, what do you expect? anyways, the reason performance goes down when hot is because of heat throttling. your phone does this when going over a certain temp. it drops the cpu speed and number of cores used until it cools down. there are ways around this. you can root your phone and flash a kernel that lets you disable thermal throttle. then all your left with is the safety reboot temp of 100C. when reaching this temp, the phone will automatically shut down. or you can put your phone into a freezer until the cpu temp is below 10C, then run the benchmark.
I'm pretty new to Android. I got my N5 2 months ago and rooted it as soon as I took it out of the box to get rid of the navigation bar. Didnt install any ROM or kernal.
What I did today was try to overclock it. I wanted to test the performance upgrade with Geekbench 3.
I got 2500. Tried to overclock with this app called: No-frills CPU control. And suddenly I get no higher than 2000...... Tried everything. I'm stuck at a multi core score of 2000 in geekbench while it should be 2500>.
WTF DO I DO? My device is noticeably slower, it's like a GS4 D: I'd rather not install any kernals/Roms
I set the minimum CPU frequency to 300Mhz and max to 2.266Ghz
Hi,
Thermal throttling..., overclocking produces more heat than the stock CPU freq so more thermal throttling. To prevent any damage, the CPU freq decreases according to the CPU temperature...
Let cool down your phone.

Sure, I'll turn it off for a while.
Just to make sure: the standard CPU frequencies are 300Mhz MIN and 2.266Ghz MAX, right?

Yes, that's right 300 Mhz-2,26 Ghz.
Not necessary to turn your phone OFF , when it boots it's a process that causes "heat" at the beginning then you will need to let it cool down again. EDIT: oups, you mean the thermal throttling OFF maybe?
Don't touch it for a while, airplane mode can help. If you are in a "hot" country/weather, air cooling, fridge...

I've let it cool down and I got my old performance back . Never knew the solution would be so simple. Thanks.
I have been able to fix quite a bit of thermal throttling experienced in multiple benchmark runs by tweaking with the thermal-engine configuration file. With just a few changes and with the copper shim mod I can now run geekbench for as many five times with almost no drop in score. After that I get no thermal throttling in single core but I have it setup to disable two cores after it hits 55C CPU temp in core 4 and 7. I use CPU Z to see actual CPU temp from the sensor readings. Even after 8 Geekbench runs the two cores are still running at full speed and the phone is registering 44C. It's warm but not hot by any means.
If anyone is interested in playing around with it just look for the file in \System\etc\thermal-engine-8994.conf
Most of it is just two adjustments. One for Max temperature at which it will throttle and the one below is the temperature at which throttling stops.

Without your copper shim mod have you found any better but safe values we can try?
At least no thermal throttle until 55 celsiius
It should be safe without the copper shim. The thermal pad it comes with works pretty well. It will still thermal throttle to whatever temperature you set it at so it won't cause any harm.
I've set the Big cluster to a max of 65C and a single A57 core to up to 71C and haven't had any problems yet. I used to get horrible performance with PPSSPP emulator. When running Tony Hawk Project 8 in PPSSPP after 30 seconds of gameplay It used to drop to 6fps and now it can sustain over 20fps after reaching 71C on a single A57 core. I only saw a maximum battery temperature of 40C and the device wasn't noticeably warmer than it was with the default thermal settings.

Well yes. Except that's the little cluster and they don't get that hot normally. It's the big cluster that needs to be modified. I also tuned my display thermals so the screen wouldn't get so dim when the phone gets warm. Here you can look over my configuration if you want.

Thanks i will try them!!
your settings somehow "unlocked" my phones cpu. lol in geekbench I found an increase of performance of 200 points in multicore from 4020 I had before maximum , now nearly 4300 .It is impressive. also if I run 6-7 geekbench in a row there is a decrease everytime ex 4200 4050 3900 3600..... but temperature stays 45 degree.
I will test them more later.

Thanks for sharing your results. That's the highest multi core score I've seen on our phones. I never gotten that high of a multi core score. Glad to help. My configuration also tweaked the battery thermal settings so now you should see faster charge times as well. The default charge rates had really conservative thermal settings and the high speed charge would drop after a while but now it will 2.2 to 2.4 amp charge through the whole charge.

Yes indeed i saw a difference in chargin thanks for your effort in the configuration. I am not very fond of benchmarks but i run some in my devices after magor changes (firmware....). This device should have been speedier because of the full hd snapdragon 810 combination. I wonder if we delete the thermal config is the device gonna be speedier? I am waiting for 5.1.1 hoping for smoother rom. Lets hope soneone unlocks the bootloader!!!! I took my precautions disabling MLT lol

I overwrote the original one ^^ has someone made a backup and can share it with me.?
I guess it depends on what you're doing but I probably wouldn't play any 3d games with those settings. Here's a copy of the original one https://www.dropbox.com/s/yb76q6qwanb9ujr/thermal-engine-8994.conf?dl=0

When you apply the settings you need to give time to the phone to 'absorve' them.
Run a couple of benchmarks, test a 4k video, reboot the phone 3-4 times, close it also.
I havent noticed higher tdmperature of 45 celsius.

I'm not sure what would happen if you just deleted the file. Maybe it'll revert to some default, or perhaps it won't thermal throttle at all which would result in auto shut off when it overheats. Probably not worth risking it without a custom recovery in case it doesn't boot.
I have notice that my phone is way quicker now. It was fast before but now it's a beast when I push it hard. Also things like PPSSPP emulator was useless with the default thermal throttling now it can beat my Tegra note 7 with 4 A15 cores at 2.1ghz at it.
Was there a problem with your settings? I noticed your settings you had shared on dropbox are no longer available.

The folder was deleted for some odd reason. I was able to restore it so the link should work now. Let me know how it works out for you.
A few questions about these settings.
-At the top where you have SS-Little_Cluster_management and SS-Big_Cluster_management is the set point the shutdown temp for the entire cluster?
-I think this one is self explanatory by the action listed but towards the middle where CPUx_MONITOR for each core is, is the threshold the temperature at which the entire phone shuts down?
-I'm not sure I am noticing the difference between SS-CPUx and CPU_HOTPLUG_MONITOR. Could you explain these?

I don't want to assume I know everything about this. Everything I know about the thermal configuration file I learned from seeing others modify the LG G3 thermal config file. I also learned some by experimenting with my G Flex 2.
In my understanding SS-Little_Cluster_management and SS-Big_Cluster_management is the temperature at which the Cluster will thermal throttle when all cores in the cluster are being used at once. From what I've seen anything with "action_type 10000" means thermal throttle. The closest thing I can think off that works like that is how Intel I5 and I7 will limit turbo speed when more than one core is being used. Except in our case this is to prevent higher speeds when it reaches a certain temperature. So lets say your phone is running some heavy multithreaded app now it's going to follow the rules set in Cluster_management. The default Big Cluster temperature is set to start slowing things down when temperature reaches 48C and to not go back to full speed until the temperature drops down to 38C. One thing I find interesting is that at about 48C cluster temperatures was about where the Big cores would drop to a max of 1.5 ghz. So I'm just guessing that this setting may play a big part on the big cores max speed.
[CPUx_MONITOR] seems to shutdown the phone when the core reaches a certain temperature threshold of 120 C and I assume will not allow it to turn back on until it drops below 115C.
[SS-CPUx] on a big core seems to slow the specific core down when it reaches a temperature threshold of 85C and to not allow it to go to full speed until it drops below 55C. However this rule can be overwritten by [CPUx_HOTPLUG_MONITOR] which can shut down a core even if it hasn't reached it's maximum temperature threshold.
[CPUx_HOTPLUG_MONITOR] just tells the specific core to turn off once it reaches the temperature threshold specified. On the default configuration core 4 and 7 are set to turn off when their temperature goes above 50C. After that core 5 turns off at 58C and even core 6 turns off at 61C. At which point only the small cores will remain on.
I hope that helps somewhat.
Hey guys,
i just got my LG G Flex 2 here in germany for christmas and im very happy with it
But there is 1 but important (for me) problem.
It only uses 6 out of 8 cores and the max clock is ONLY 1.6 GHz...
in Antutu im even behind the LG G4 with that "SLOWER HEXACORE" ...
Can someone help me and tell me how to get rid of those 2 problems and get 2 GHz for the Big Cores?
Also, how to easily root my german H955 with Android 5.1.1 ?
Thanks for answers and help
Edit: I got "V15-c-EUR-XX"
Edit2: GPU runs 600 MHz max instead of 650 MHz ...what did they do with my phone
Edit3: I already checked temps, before you ask. 35-40°C max.... i dont think it should throttle at that low temperature.
Okay, now, on the next day it shows up to 1950 MHz for those 4 cores.
Seems to be a temperature problem at only 35 °C ...
Whats the easiest method for rooting the flex 2 (V15-c-EUR-XX) ?
I am not sure if for this phone is the same, but sometimes if u have low battery the kernel switch some core off.
Its normal,sometimes it underclocks the CPU and not always is phone running on 8 cores.... And what about GPU? Well,i have same distribution (DEU) and max is 600 MHz,but currently i have it on 305 MHz. Personally,i never saw higher clock of the GPU,and i own this device for almost month.
Edit: the GPU underclock may be caused by Energy saving mode. However,this has no impact on CPU,CPU-Z shows 1,96 GHz even in Energy saving mode. I had same problems too,CPU-Z showed 1,56 GHz maximum,after restart 1,96 GHz max.
Thanks for the responses. One last question. Why do i get only 60k in Antutu where others get 75k+ without fridge or such?

Well. about an hour ago i ran Antutu test and got 68 000 points. However,it was much worse before (first antutu test had 48 000 points and i was shocked). There are many things that can influence the score. For example-power saving mode,current RAM status (how many apps you got in background),battery percentage and temperature. Maybe best time for test is cold start,when you jump right to Antutu after start (of course not right after,phone needs some time),because you have lowest temperature,highest free RAM and no background apps. If i did such test, i would score more points i think. And last thing-the performance drops significantly when you do many tests in in a row (i mean 1st test and then in about 10 secs other one)

Yeah my performance also seems to increase over time. Weird.
And yes this soc throttles easily. But it doesnt get as hot as my nexus 5 was sometimes with benchmarks and is still faster when throttled. Would not call this processor a fail at all.
Still hoping that the SD820 will be better in thermals though. But this chip is still more than what I need.
How is the battery life when it runs on lower clock speed?
Can someone please use the phone with underclocked cpu (1.6 or 1.8GHz) for some days and post the experience on battery, temperature and phone responsiveness? Thanks.
Battery life is not improved when the phone runs in 1.6 GHz mode. I usually get about 3 h screen on time. The phone heats up a lot under load. I never saw my phone using the full potential with this Snapdragon 810 CPU. It always runs at 1.6 GHz and that seems to be fixed by the ROM on mine.
I rooted my phone and I'm using the performance governor that maxes out my cores. I also set my GPU to 3/4 Max frequency. I was playing Shadow of the Colossus on aethersx2 Playstation 2 emulator and my phone temperature got up to 83 Celsius. Does Android 11 still send a warning or automatically shut down the phone at these temperatures on a rooted phone? Because so far I have not received a warning. BTW the game runs great and does not seem to throttle even with accurate emulator settings.
