[Q] G2 Gaming Slowdowns

I mainly notice this with high quality 3D games like Dead Space, Mass Effect Infiltrator, and Shadowgun. But basically if I reboot my phone and then launch one of these games it plays like a dream. Smooth(ish) and no slowdowns. But after 15 minutes of playing fps starts to drop, and after 20 the game is unplayable. If the phone has been booted a long time, the game starts laggy and is also unplayable.
Running CM7.2 overclocked to 1.3Ghz and using V6 script. Usually always have around 200mb of RAM free. I'm guessing it has something to do with caching, at least the consistency in the time period seems to indicate the phone is getting bogged down with something after a certain point.
Any settings that might be able to alleviate this? Or do I just have to cross my fingers that Google announces those 5 Nexus devices in November?

i noticed you're using v6 supercharger, with that, try run engine flush from time to time (or put it on a schedule)
also you can run the detailing to "defragment" all your apps, for better performance

[Q] Galaxy Nexus CPU temp

Hello all
This is my first post and Galaxy Nexus is my first Android phone.
So, when i bought my GNex it was on stock and I use Stock ROM about 3 days. In that period he never get any warm - not even whet I play Angry Birds RIO for about 30min.
Then my brother install me latest AOKP ROM and Franco kernel - great stuff, but now I feel heat around camera
I use TempMonitor PRO app and this is my results :
all apps close, not starting anything - around 32C
Gallery, cam, some apps started and closed - from 38 to 42C
Playing games (Angry birds RIO, Space, Sentinel HD) - 48 to 52C
My question is this :
Is that normal temp? How does Stock didn't heat that much
Tnx and i hope this will help if someone have the same question

Hi,
Your CPU temp is absolutely normal,no worries.And while playing games it's even perfect.
How does Stock didn't heat that much
Click to expand...
Click to collapse
You're not stock now...
After it depends at what CPU freq you're running,voltage,ambient temperature,etc...but here it's perfect.

I just posted in another users similar thread about their phone getting hot (he said "extremely" hot so hes likely going way past your temps). I too have found my phone to be warmer when running AOKP Build 38. I've run the Stock ROM and LiquidSmooth with Francos Kernel (also tried Provision briefly but it had some issues I couldnt overlook). AOKP gets the hottest by far for me (both at stock CPU and OC to 1420).
I plan on switching ROMs again soon and will take note of temp then

If you use a less feature rich rom you might have less heat issues.
I suggest using the trinity kernel together with a cm9 rom.

Your temps are fine but if you want to find something a little "cooler" try out different combinations. For me, CM9 and Trinity Stable 65 at 1344/384 stays pretty cool while gaming. Ultimately it is going to be a factor of your clock speed. You can adjust the frequency of your CPU back down to 1200 (1190?) and you'll see the temp difference. You might also see it slow down during certain UI interactions. Just play around with it, but your phone is still considered in the safe zone at those temps. They have thermal protection built into the kernels as well so even if something crazy happened your CPU would back off until cooldown and if it can't cooldown, it'll shut off for you but that would be a very rare condition. I've never had it happen and I've ran at 1650Mhz for a long time.

Tnx all for info. Great help!
Hmm it would be nice to get back to Stock but to keep root and maybe to install franco kernel... What you say about that?
It's iritating to play game 5 min or look pic in gallery and to feel heat in phone!
One more thing because I'm new in this stuff :
How to get back to Stock? Is it hard?

Your CPU is probably overclocked, don't worry, as long as it stays UNDER 55 degrees C, nothing will happen, if however, it goes over, it will burn your hand, if you're unlucky, it happened to me, with my GS II...

Hi,
Why under 55°C???
The stock temp limit before thermal throttling is 64°C and in Francisco's kernel it's at 75°C.
And the max before the CPU shutdown is 110°C...The extreme protection and the extreme overheating
So above 55°C no worries...In any case if you don't disable the CPU temp limit (like in some kernels->Morfic,Glados and eventually Francisco but not (yet) in his app) you're good and before 110°C->thermal throttling->lower CPU freq according to the CPU Temp limit.
His CPU temp is actually normal,don't say stays under 55°C....56/57/58/59°C,etc...to 64°C or 75°C,no problem unless you stay at 75°C during 1 hour...
With that you said the guy no longer used his phone for browsing 5 mins in the sun...

55 is a very low number and i would suspect most stock GNexs would go above that routinely under heavy load.
I've had my phone up to 66 and its nowhere near burning. Its warm to the touch and thats about it. Now if you are somehow putting your hand directly on the CPU (i.e. not possible) then yes that might feel much warmer.
Basically if you manage to burn yourself on your phone either its already fried or someone lit it on fire

After playing ShadowGun around 15min I get temp. around 65C?! That is really hot - for me!
I think to get back to Stock... This is way hot for me. What you say about that?
Can anyone post link how to get back to Stock? Guys this is my first android phone and if I get bootloop I will get a heart attack, really I will get one

Honestly don't be afraid of boot loops as you can most likely still get into recovery if that happens and all it takes it's a bad download of a ROM or forgetting that such and such kernel is incompatible. Be afraid of bricks and soft bricks lol. Although if you take the time to read before doing anything you'll be fine. Also just download a sick image for your phone from the tool kit to go back to stock. That's the easiest way.

Hi,
65°C after playing 15 mins of an "intensive" 3D game...I don't see where is the problem...It's absolutely normal...
How can your CPU temp will be at 50/55°C (about,for example) after playing 15 mins of game???
You hope what temperature?
Which cpu frequency?GPU?Undervolt?
Don't focus much on your CPU temp,if it's overheated->thermal throttling...And in extreme situation...just a reboot...
It will be the same thing with the stock kernel,you will get the same temperature under the same conditions (playing)...

Unfortunately that's the way it is right now with dual core phones. My phone regularly gets too hot to even touch when playing games for over 30 minutes. I called to speak with samsung about it and they pretty much brushed it off as normal. I'm running on cm 9 with a franco kernel

[Q] Is overheating still present in Jelly Bean?

I remember reading somewhere that it was a software not hardware problem so JB could have a fix for it.

I've never had an overheating problem. I also don't recall many having that problem.
Sent from my Galaxy Nexus using xda premium

Overheating? I've never had any of my phones overheat, on GB, ICS or JB.

Are people really having serious overheating (as in phone crashing or shutting down from heat) on a stock device? I have a feeling anyone overheating on ICS is running a custom ROM with voltage changes or overclocks.

My GNex on AOKP and stock voltages does overheat while, for example, playing Modern Combat 3.
Ok maybe overheat is a wrong term a bit since it never crashed or force closed. It just gets fairly hot in the area above camera.
And I'm asking people who did have the problem and upgraded to JB.

My GNex does seem to be running hotter than normal on JB than ICS but not by much. No serious overheating problems at all.

Getting hot and overheating are completely different. The phone gets hot where the battery and processor are, that's just how its going to be, especially when playing 3D games.

No no, my battery stays fairly cool (39 celsius degrees) but the area above camera compared to that is really hot. Way too hot than I think it should be. My previous phone - HD2 was never that hot unless I overclocked it.

Around the camera is where the processor etc. is. The HD2 is also severely less powerful than the Galaxy Nexus.

My cdma nexus doesnt seem to get as hot. I havent really noticed it as much as i did on ICS.

I've been getting overheating since Jelly Bean. Keep in mind that google "improved" things by ramping the CPU up when the screen is touched, even if it's to do a simple task that doesn't require full CPU power... this might exacerbate the overheating issue if you're actively using your device.

Way less then usual. Maybe 50% less. when it does it gets a bit hotter.
So in conclusion I think it's better at this job then ics.

It doesn't ramp it to full clock speed, it ramps it up one step, or two, whatever.
Ramping it up to full speed on every touch would murder the battery.

I've tested it. It ramps one CPU to full clock speed when you move your finger around the screen.
Try it yourself. I wish I could turn that feature off since using Swype has now become an issue...

While on ICS, it'd get up to around 70°C. Now on JB, it usually tops at around somewhere in the 60s°C.

[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
Sent from my GT-N7100 using Tapatalk 2

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.

HTC 10 very poor performance

hello,my htc 10 performance is very poor so i decided to stress test my phone using the antutu app.
as you can see the cpu load is varying between 80-90% but the speed deosnt pass 1200-1600 mhz range. the maximum frequency is 2200.。
i have lag in almost every graphice intense game
i have poor performance and i dont know what to do, should i return the phone and request another one or is there something i can do?:crying:

Im getting pretty much the same problem, download an app off the playstore called fps test and can you tell me if the framerate seems to stick at 50fps then jump to 60fps then back to 50, or just stays at 50.

Yes i tested and i got about 49-50 fps then after about 15-20 seconds it jumps up to 59-60 and comes back down

Yeah I think that must have something to do with it, im getting that too and my phone seems really slow also. I wonder if its a defect, I just got it the other day. Can anyone else who has their phone working normally also test?

This is normal for games, smartphones are not an highend PC.
Also, read post 6 in this thread : http://forum.xda-developers.com/htc-10/help/laggy-homescreen-gaming-t3434178
It probably has something to do with software (HTC firmware).
What game did you test ? Alsphalt 8 is pretty bad optimised

Just the basic google search,also cache is cleared and i factory reseted the phone a week ago but it didnt really do anything

Just did a stress test in antutu like you did.
My wifi was turned off, no apps in background, everything stock, new phone.
I got almost the same results like you, a bit better though, but my cpu speed frequency doesn`t go over 1600 mhz. It looks like this is normal. 820 cpu can run at 2200, but it is always a bit underclocked on smartphones.
It must be that software (HTC firmware) is doing some harm to gaming

Try downloading an app called fps test, its icon is an orange circle. Can you see what the framerate is on it/ whether its stable. I've never ever had this problem on any other phone.

Read something yesterday about HTC shutting down one of the cores once a certain temperature is reached, dunno if that is what's causing your issue, there was also a work around in the rom / kernel section which upped the temperature before the setting kicked in...

Have you turned on High Performance Mode in the developer options?

HTC 10
This isn't as simple as saying its the phone itself. Android is an open source OS with a number of different devices so it's harder to optimize games for every phone, then with the higher screen resolution on newer phones this can also slow down frame rate. Another thing that has caused issues is the Nougat update which they are suppose to fix soon, this could be why an older phone runs games smoother due to lower screen resolution and and older version of Android which has had time to be perfected and receive necessary updates. The HTC 10 is actually a gaming beast compared to other Android devices. With the HTC 10 you can go into developer options (by going to ABOUT phone and clicking on "build number 7 times, developer options will then be added into your settings. Inside developer options you can then click "high performance mode" which will over clock your CPU to boost performance (only use when your phone is plugged in because it will drain battery fast). By scrolling to the bottom of the screen click advanced and you can then turn off animations (this will make your phone a little faster). If you want higher frame rate click (force gpu rendering) this will help boost frame rate by offloading graphics onto the gpu freeing up power of the CPU (this may or may not degrade graphics slightly). If you want to improve 3D graphics you can click "4xmsaa".
