[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...

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

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 )

Battery problem and gaming problem CM 10

Hello,
23 november I flashed the newest version of Cyanogenmod 10 on my HTC One X and it works very good!
Because of garanty I had to flash back to the stock rom.
27 november I flashed again the newest version of Cyanogenmod 10 and I have 2 serious problems.
With the version from 23 november I had around 3,5 hours screen on time and with the version from 27 november I had only 1 hour screen on time before my battery is low. There is no draining app when I look by Settings --> Battery
And when I'm playing a game like Bike Race, GTA, Shine Runner, Temple run ...., my phone shuts down automatically after 5min playing.
The temperature is around 49 celsius / 120 Fahrenheit. So that isn't the problem.
Every day I update CM 10 with OTA to the newest version but I still have the problems.
Does anyone know the solution or the reason?

do a battery calibration.
this can help:
https://play.google.com/store/apps/...xLDEsImNvbS5uZW1hLmJhdHRlcnljYWxpYnJhdGlvbiJd
remember to fully charge your phone before you calibrate battery.

Currently Im doing the battery calibiration.
I hope it will works.
But the problem with gaming?

The battery calibration works perfect!
Thanks!
But the gaming problem isn't resolved..
I think it is an software problem in CM10.

Not more people with this problem?
With GTA Vice City I have also the problem..

3 Weeks ago i flashed back to the stock Rom and the gaming problem was resolved.
Today I flashed again CM10 with the version from yesterday but than I still have the problem.
More people with this problem?
The problem is that when I play a game, then restart the phone after 10 minutes again. The temperature is around 40 degrees.
CM10 is a very nice rom but this problem is really annoying.

That's the battery temperature, but what's the cpu temp?

[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.

My Fix For HOX Tegra Heat Problem

Hi I don't know if you guys read my last thread about me being really wanting to extend battery life and reduce heat on my HOX. What I did was simply using Blade Rom + used only 2 cores instead of 4. Performance wasn't really affected (except for gaming) and I was really happy.
But now I really wanted to try something new and was tired of the Sense interface. I ended up flashing tons on mods and bricking my phone. So I had to wipe it fully and reflash. I installed Blade ROM v4.6. Two days later I saw that it had a de-sensing script which sounded nice to me since I was tired of sense. To my amazement (though i don't have exact temperature values), the device is now running much cooler and it feels much nicer in my hands. Still a little warm but much less than on stock or custom(with sense).
I believe Sense to be causing a big percentage of that heat ... well at least this can be derived from my observations. Im not really sure if this has been posted before but I saw a lot of threads dealing with this problem and I hope this helps someone.
P.S When I de-sensed i think its now using Nova Launcher

Theres something wrong with your HoX , my hox never gets *warm* or *hot* on regular use even with all 4 cores on, when playing demanding 3d games (nfs for sintence) it reaches around 35-40C max, while playing it being on charger then it gets *warm* or a little bit *hot* HoX shouldn't be getting *hot* if you're using it normally lol, only while playing 3d games on charger. At least that's how it is for me.

what heat problem??? heat is now ancient history ever since the JB OTA
your HOX or your custom ROM has a problem

Exactly. Now even when playing taxing games like GTA 3, GTA Vice City, NFSMW, the phone stays cool. I remember on ICS< the thing heated till 50 degrees + and shut off by itself ...Thank the lord for the JB update :victory:

My phone gets overheated when playing games on charge. I'm on stock JB Rom. When I was on stock ICS Rom the phone didn't get overheated regularly, but when I updated to JB it gets overheated so fast.

You shouldn't be even playing intesive 3d games while on charge , that kind of stuff are killing your battery , not straight away but over the time, anyway once someone said about this *gaming while charging is same as $hitting while eating* =) , anyway it can also depend on your rom/kernel. I used to play games while on chrager due to addictivity of games tho never got really overheating issues, few times since i have it.

I think the problem its the kernel i have official rom jb and my hox overheatind too lm play games not while charging.

ViperX 3.3.2 stock kernel, didn't test it for gaming long period , but gaming seems to be smoother then back in ICS days for the time i tested ( up to 10 mins each game) , didn't overheat or anything durring this 30 min test period for me, tho it's expected if you play for example NFS MF for over a hour or so to get little bit warm, but shouldn't go over 35-40C off the charger, anyway you gotta remember heeting on hox can happen as well if you're in warm room , tested that lol, played NFS in warm room at my house , actually very warm room around 30C and in another room with maybe 10C in the room, phone was much cooler then in the previous room , as for playing it on the charge it got overheated in around 20 mins of playtime in the 30C room and in the 10C room stayed little bit warmer but not overheating. So conclusion = one part of overheating depends on the room temperature lol. which means hox should be literally unplayable with charger when the summer time comes =P (btw this heat test was done back in ICS days not JB , anyway JB seams to be much better for this matter )
- Edit - this was meant for this
