N910C Lag in Games
Hi Guys, Like most of you I have some game lag and drop in performance and low benchmarks varies from 40000 43000 and low scores in 3dMark as well, I tried to put my phone on a cooling ice pack with good insulation to avoid evaporated water to get in the phone anyways I ran the test again and I got 53218 in Antutu and Maxed out results in some tests and top scores in 3dMark, so any idea what to be done about this to keep the same steady performance all the time?
Q: WHY did you try put your phone on a cooling ice pack? How did you go from performance to ice packs?
Have you checked what processes you have running in the background and closed these to free up resource.

The performance increase is due to the CPU and GPU not throttling down as they are not hot, which should be the case all the time not after 5 minutes of gaming

Was wondering if anyone might of experienced it (although it's kind of hard to tell if it's even happening).
I noticed earlier I was playing a game that my tablet was pretty warm, and then I immediately went to Rom Toolbox. My governor was set at Performance, and both sliders at 1.7GHz, but I noticed the clock speed going down in increments of 100MHz (1.7GHz to 1.6GHz to 1.5GHz to 1.4GHz) and then back up to max, and it did this a few times and then finally stuck at 1.7GHz, when the tablet was a little bit cooler (I think).
While running StabilityTest (the CPU+GPU Stability Test on Full Details), clock speeds are constantly changing between 1400MHz, 1500MHz, 1600MHz, and 1700MHz with the Performance governor in-use. The top-left of the tablet is also noticeably warm.
Edit: It drops to 1300MHz and even 1200MHz at times too as the test goes on. Might drop lower depending on how long it's ran.
Very interesting, that would explain some of the slowdowns I am seeing whilst playing Asphalt 7.
Please note that the Stability Test is not a "CPU Burner" test, it does other things as well (checking the RAM, testing the GPU, etc.). So it's to be expected that it doesn't run at full speed all the time.
I've done some intense gaming on mine, and while it does get a little warm in a small spot on the upper left side, it's nothing abnormal. Now if you want warm, try the Acer A700, that guy gets hot on the back due to a poor heat spreading solution.
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.
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?
Best regards,
dingolino
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.
Best regards

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.
Hello guys,
I want to heat up my nexus 4 for a video (don't worry, it will be cooled by ice cubes ).
Is there any possibility to run CPU and GPU at 100% and produce the maximum amount of heat?
Belive me you dont want to do that because you can damage digitizer and battery, even with ice cubes...
@chewu.pg: But I don't want to turn off thermal throttling, I just want to get it warm as it gets while gaming, but without touching it.
I m just curious .. why you want to heat it??

Time lapse of two ice cubes melting, one sits on the back of the phone on the top where it gets hot (where the cpu sits) and one on the bottom.
And water entering phone ? Its ok if you arent going to turn off thermal throttle ... You can use various stress tests to heat up phone like antutu stress test or a continous gpu benchmark can do the trick

It's wrapped.
Thanks, but how long does the AnTuTu stress test run?
So in case you were wondering, this is my result:

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.
