galaxy nexus cpu throttling on jelly bean?

hi there i got a used galaxy nexus from someone and installed android me 4.1.1 (version 1.6)
now my problem is, when playing intense graphic games (GTA III or dead trigger) i notice the fps drop and rise in the game.
At first I thought the game itself was lagging due to too much happening on screen (such as more characters) but it was not the case.
The game would be silky smooth for 10 seconds then choppy fps for the next 30 seconds... rise and repeat..
it seems the cpu keeps underclocking/overclocking itself... i even tried force closing all my apps before running the game and it helped with the fps a bit but the throttling is still there....
anyone had any similar issues and knows how to fix it?
edit: forgot to add, does your phone get really hot behind the LED FLASH when gaming? Mine gets really hot even on the screen too (On that side of the phone away from the battery)

Stock rom? custom rom?

sorry its custom rom (android me version 1.6 july 29th)
although i briefly remember this happening on the stock rom too so I don't think its a rom issue...
hard to say i can't post in the developer section yet... so i guess here to find out if people are having issues with the stock?
stock kernel if that makes a difference

Wow am I the only one with these symptoms? Hot screen and lagging frame rates? Since no one is replying maybe my CPU has cooling problems? Bit there is no fan haha

Any news about your problem? I have the same problem with jelly beans stock. Playing the game agent dash when the nexus is cold is fine when it is warm slows down, like a drop performance. How did you solve it? excuse my English

Try putting the graphics for the game on low

same problem also there are many persons with this problem.I'm on stock 4.1.1

If the CPU runs hot ( > 64 degrees Celsius), thermal throttling will kick in by reducing CPU clock speed. Works as designed.

You're not the only one who faces this problem - I face it on the stock ROM. The only way to alleviate this issue (not entirely, but to quite an extent) is to overclock your GPU - which means using another kernel that's clocked at 384mhz... which, for me, seems to break VPN (at least it breaks it on Air Kernel - Faux works for a while, then stalls... I don't know the nitty gritty, but that's what seems to happen - YMMV).
I had a thought: what if we enabled GPU acceleration in the developer options and then played it - do you think that'll make a difference? It does, generally speaking, make a difference to the other programs (apart from breaking some )

[Q] nova 3 lag overheat build prop sugestion request

Im using my new note 2 n7100 to play nova 3 from the play store on stock 4.1.2 the game randomly lags on some levels and
Heats the phone and screen. Restarting the phone makes it smooth again for few mins. Can anyone recomend a build prop i can use
For a better experince or config?
Mc4 lags a bit but is mostly smooth, im not using any extra apps im not rooted ram minimum use is at 533mb. thanks for the help

Sorry my friend, a build prop will not work as such, the problem is the power required to run the game persistently at 30fps or 60fps.... ^__^
I have that problem with Vice City... Hot as Hell ^__^

I dont mind the heat so much but is it possible the cpu is being downclocked due to heat? Because there is sudden lag spike
But goes to normal smooth gameplay after restart. Does overheating cause this problem in nova3 and is there any way to prevent downclocking?

Nova is a gameloft game and most gameloft games aren't optimized for our Samsung Android phones. I play modern combat 4 and it doesn't run smooth most of the time. Compared to ios, which is highly optimized for gameloft games, it plays like a sideshow.
Contact gameloft and complain. It's all we can do.

Try undervolting if you think its the cpu throttling. ..
Helps
But not the heat though. ...
Has to be some heat

I put set cpu to run at 700mhz the game ran fine with the same lag spikes and the heat was the same. So i guess the heat is from the ram if thts possible. Its a cool phone but i wish it could stay warm and play gloft games smoothly . Im not a fan of the iphone screen or ui but i guess i have to get one. Iv written to gameloft about dark knight, wild blood and nova3 lag issues perhaps they would look into it.

On a side note is there a note 2 compatable version of 9mm?

Ok iv figured out the issue. The problem isnt so much with game its the cpu. At every lag spike the the temp has hit 60 degrees and the cpu downclock or throttle has caused the lag. Iv posted on the q n a thread for suggestion to stop throttling. Sadly this will happen in all 3d games to some extent due to the thiness of the device.

Try using a custom kernel to undervolt or even underclock. While underclocking might not seem that much of a good idea,underclocking by say 100mhz might stop the phone from throttling (which downclocks to 800mhz) so it might be worth it. Personally I can run most games at 1.6GHz without any throttling (which for me happens at 70 degrees using Perseus)

I do not know your enviroments degree that may change the way the phone behaves. Right now it is freezing outside and 22 Celcius the room. I have no CPU backing down due to the thermal conditions even after playing Nova 3 like 40-50 mins. I normally use my phone locked at 1200 Mhz Max since it is more than enough with 640Mhz GPU but I have been using it at 1600 Mhz CPU with 533Mhz GPU and there is a little more heat on the camera side. Still it is tolerable for both my hand and the device itself. No lag so far.

Thanks for the reply im in southern chennai which is pretty similar to a summer in california. Im not sure how to downclock the gpu but the phone screen near the camera becomes really hot while gaming nova 3 or mc4. The temp shows as 56 degrees c. Iv a hard time touching the screen near the camera at tht point. The back is still ok. In india samsung does not give out refunds or exchanges so i hope there is some sort of fix for the screen heat.

Performance issues and low Geekbench 3 score

Hey,
I have a problem with my Nexus 5X. Overall the daily usage is pretty much the same as last week, but when I will start a bigger App or a Game the phone becomes slow. I closed all apps and restarted the phone. Then I started the Geekbench 3 and the score is so low! I don't know why. I attached a screenshot. Can anyone help me?

What firmware are you using?
Dont look at benchmark's score, it doesn't reflect real performance of phone, e.g my sgs3 gets 40k in antutu but nexus Just 45-50k
Lower performance in bigger apps is caused cus when CPU reaches 55*C it turns off cores to reduce heat, you can change it with custom kernel.

I have the newest security Patch. And the Geekbench is just to demonstate how slow the device is. The Performance issue Starts when I open a game or a big app. The phone is cool and it heats up minutes after playing the game.

But is it slow in daily use? Or Just in big apps?
Look on ur average RAM use, maybe some apps make ur phone slower like fb messenger (it can take even 500mb up)

as already said, phone benchmarks mean next to nothing these days. closing apps also rarely helps speeding up a device. removing apps from the recent-screen doesn't close/stop an app btw, they redid that quite a while ago afaik.
and as a last note: restarting the phone is a very resource intensive and long process and can easily take until long after you are already able to use the phone again (mediascanner, background/system services and apps starting...)

I don't have the Facebook Messenger. Ram usage is around 1.3 GB. And it's everytime. Not only when it's restarted. I don't have Cleaner Apps or security Apps. The Speed changed ca. 2 days ago. Last Tuesday everything was fine. Benchmarks were fine, Apps were fast and everything was smooth. But then I don't know.

So that's very weird. What did you install whole last two days?

Only the game Smash Hit. I have wiped data and Cache. It didn't helped so I Uninstalled the App. Still the same.

Hm, So I'd recommend reinstalling ur rom, what would you say about it?

I can do that, but its really annoying when I must Reset my phone until a week.

So it has just a week?

It's my first week with this phone. It's completely new!

Wow So I'm surprised bro. Don't you have any another issues typical for Nexus like yellow screen, slow AC charging to make a complain?

Yes. The yellow Screen. But its fixed with the Developer Option "cooler colors". Buildet was this phone here in October 2015.

So, you can try to make a complain or Just reinstall rom /change kernel. No other way

I don't want to loose my warranty .
Edit:
I have wiped my complete Cache again and the score is a little bit better. Also the game. It's faster but not as fast as before.

If I'm not wrong you can take back ur warranty by flashing stock and locking back bootloader

I don't want to change anything. Are there no other possibilitys?

Solution
I had the same "problem".
Try to lock your phone and leave it to rest for few minutes. Then unlock the phone and run geekbenchmark 3.
You should get normal results now (~1230 for single & ~3500 for multi-core).
I hope this helps.

I'm facing exact same problem, bought my nexus 5x almost 1 month ago I did the geekbench but the scores were very low specially single-core, so I head up to couple of forums they suggest to reinstall the geekbench app or install the 64-bit version of it. I didn't get the 64-bit version of the app nor there is any stock setting on the phone to run apps completely on 64 bit. ( Note: Im no pure stock, never rooted, locked bootloader )

Gaming perfomance

Hi Guys , i just brought this tablet and i can say is a very good one , i got this for 65$ used in my country with like new conditioj minus original charger. But never mine i can charge using original ssmsung charger with same speed like the original one.
I can't imagine if i brought other used tablet with thr same price range tough ie, gal tab 2 , ipad mini 1 , note 8.0
My problem is the tab playing games for mobile legends and aov id bad, i can play mobile legends max setting in s7 edge with smooth perfomance while the tab only can run mid setting with no shadow. While aov is more crazy with min setting for stable gameplay fps
I know it's too far comparing the exynos 8890 to snapdragon 600 , but i see the tab can play nova 3 with its full effect
Right now the custom rom is pure nexus 7.1.2 maybe i will try to flash it to stock 6.0 to see if there's a better perfomance

Back to stock and the perfomance was not smooth as purenexus , even coc lag and opening app doesnt smooth. I will back to nougat custom rom with flo elemental kernel to oc gpu hope it will be stable.

now with 7.1.2 CRdroid and elementalX kernel ,@ stock with gpu set to 491 mhz and i love the perfomance and everything so far. Gaming was great except two top of my games
Mobile legends need to change the res to 1280 x 800 , basically the original nexus 7 res to play with max setting and it ran smooth. While Arena of valor is actually is i think the heaviest games on android, it still lag and i need to turn setting to med for the fps to be stable, the max setting can drop to 20 fps with all the effects

I notice with elementalXKernel and gpu clocked 450mhz and mode perfomance. The game almost run smooth for both games at max setting and native res, only when skill spam and there's effect everywhere the game start to slow down a littme

Try android 4.4, people say that gaming was better on that version

Okay so , both games now run ferfect in full hd res first my setup
CRDROID8 rom with elementalX kernel
cpu clocked 1.5ghz elemental gorvernor
and gpu 450mhz stock ondemand gorvernor
Mobile legend case is funny as it need the gpu gorvernor to perfomance to prevent slowdown, but mpdecision can still be enabled to get smooth perfomance
games run fine with gpu gorvernor changed to ondemand and setup like above, no stutter or slowdown. But using simple gorvenor will give stutter and slowdown .
Arena of valor need mpdecision to disabled, if enabled the fps will stutter quite heavy i dont know why, but i think this because how the app coded. Like 3dmark that require cpu processing for physics. The game run fine tough with any gpu gorvenor as long the mpdecision is disabled

Help with my Mate 20?!

So basically I just got my mate 20 yesterday and I just did an antutu benchmark right after I open it and got a score of 313k without performance mode... Right after I tested it I then proceed to update it to the latest version which is the 0.146 and got an average of 205k?! Without performance mode on and got 305k with performance mode on can someone explain what happened pls? Also whenever I go to the menu I get white or black screen for my open apps rather than what's in the screen of it

Sorry to hear that. Maybe you should do a factory reset before you invest too much time setting it up.

Actually the second problem was solved now... I just needed to restart my device... The only problem now is the 1st one which talks about the speed... I can reach 305k with performance mode on but with it being off It can only manage to average around 200k... Is this because of the updates?

It's because of useless AnTuTu

How come klanac??

What do you mean how come? Antutu and other performance measuring are pure crap. Even Huawei admitted they manipulated the scores of these programs before.
Do you feel the phone got slower? Hangs? Application shutdowns? Then you have a problem.
Antutu not stable then you need to get out more often man: D

I see... Well it has bugs like the auto brightness which seems common for some people who has the mate series but so far its been performing good so I'm happy

the phone overheats on stock kirin 980 speed while doing any extensive work for sometime .. also it uses more battery .. so they limited full speed to performance mode only .. but i get 265k without performance mode and 305k with it
