Phone too hot to touch after 5 minutes of gaming. - Galaxy S II Q&A, Help & Troubleshooting

Hi all, running lite'ning rom 1.4 and just played order and chaos for 5 minutes and the phone became too hot to touch! Surely this shouldn't be right, i mean what the hell! Anyone else have this?

Actually yes,many people have this.It's the CPU overheating.Beware,it doesn't get hotter than other CPUs on the market,but heat disipation on the GS2 is minimal as the phone is so thin.
The only thing you can try is lowering the CPU clock to 1000Mhz or even 800Mhz when gaming.You can even boost your GPU to 400Mhz up from 267Mhz and don't overheat then.There will also be no performance hit as games run mainly on the GPU and two cores running at 1GHz are more than enough to handle the background.

I havent noticed the phone getting super hot as some people have noted. I do notice that it does get a lot hotter if its plugged in and charging while playing a game. Are you by chance charging while playing? If so, I'd try and play while not charging to see if it gets really hot still.

No this isnt while charging and it literally was 5 minutes of playing! How do I change the cpu and gpu speeds safetly?

it also depends on the game itself, many of them are just poorly programmed
to your question: setcpu is the app.

I dont have an SGS2 yet but your statement has a total flaw, if games mainly use the GPU then there should be zero need to underclock the CPU.

Have you ever seen anything running on the GPU ONLY?What I mean is that the GPU processes the graphics,which are important when playing a game.The CPU takes on other tasks,like opponent's AI(artificial intelligence),background and foreground code running and many other things.Sound maybe?All these things keep the CPU running at 100% for no reason.Lower the clock and voila!
Check first before you try to say I'm wrong next time.I don't usually say bullsh!t with such things.

First, you crack the bootloader.
When you've done that, I'm guessing you allready figured out how to OC the CPU

For now just use the overclock widget. set top two settings as high as you want up to 998 click on off screen frequency. set between 246 and next number you choose. set at boot save. define settings at what mhz you like and experiment. do not run on screen and off screen freq at max. i have had my battery sweating and even plugged in all day and not gained a single % of charge. until boot loader is cracked.... this is all you can do.

Although it's impossible today because of bootloader, note it's always dangerous and not great to overclock embedded cpus.
You can't overclock a lot, as you have a battery (X10 works about 5-10 hours with full speed - 998MHz), and the CPU only has passive elements to cool. Overclock can damage your CPU and your motherboard, stress all elements and low your battery life (battery charge and cycle of charge). (Even there's a self shutdown when too hot)
You can get an idea of overclock on Nexus forum, as we have the same CPU (Snapdragon 8250) - I saw overclock up to 1300 MHz, but it's really not looking safe to me
Thanx everyone..

Depends also on the voltage (as long as your voltage isn't increasing as you overclock, it isn't really that harmful as long as you watch the heat), and what you have your underclock speed set to with screen off (as this can in some sense reverse some of the possible "damage")...
I had my htc hero overclocked to 710 with the screen on, and underclocked 176 with the screen off and it ran a lot better.
I digress, I see no purpose in doing so when you already have a 1ghz processor that is super fast. I only really see a point in overclocking if the possible benefit is greater than the possible harm, and in this circumstance, I really don't think you would see that much benefit.

I have seen considearable difference when maxed out. however the dangers are high of overheat. ive done it once and onetime only. kept on and off screen at 998 and hat it plugged in all day with out a single gain of battery. it was like on life support and was hot enough the phone was sweating even when sitting next to a fan blowing on it constantly.:-( since then i have made adjustments to run between 700 and 998mhz on screen and min 246 and 400mhz when screen off.
if looking for better performance without the overclock and good drain of battery, download and install sysctl from market and follow settings below.

Not in all instances. Depends on the quality of the chip. Lot of chips are capable of handling higher speeds and temps but are set lower quality assurance.
For instance, I've got a NookColor that has base CPU set at 800MHz and is now overclockable to 1.2GHz
We'll have to do stress tests on some to see what they're capable of.

Agreed.
My Motorola Defy has a Omap3630 that comes at 800MHz,stock but can be easily overclocked to 1.3GHz without a sweat.
Just depends on the chip's capacity of "Stress".

Safeness of 1600mhz

Has it ever been heard of that someone killed their gs2 from using 1600mhz in daily use?
My gs2 likes to have 1475 as a minimum voltage for 1600.

Ever rev an engine into the red? Did the engine blow up on the spot? unlikely. However if you constantly KEEP the engine in the red it will eventually break down.
Same thing for OC phones. The processor in the SGS was designed for somewhere around the 1ghz mark. Pushing it 110% likely wont kill it, they build allowances and tolerances into these things to help them last longer. Push that processor to 150% and you are risking serious damage.
Monitor the heat, if you notice its getting HOT then you should really pull the battery and let it sit for a while. Nobody here can say its safe to OC your phone like that, its a calculated risk you obviously didnt spend a lot of thought into.
TLDR: Just because you CAN doesn't mean you SHOULD.
Actually its my thought the reason I haven't been using it on 1.6 yet, and why I'm asking. Iv been ocing my pcs since the late 90s
Now the reason I'm asking here is because the cortex a9 was designed for up to 2gHz operation, but this phones design may or may not provide adequate cooling, that's why I'm asking if other people have any negative experiences with this.
Were not actually over reving the chip its more of a environment issue with cooling/ventilation.

You do have to have in mind that PCs are much safer to OC, so we shouldn't really compare brtween them.
Regarding the Phone OC, I haven't OC'd mine and probably never will because I have all the horsepower I need, but I think the "safest" OC is between 1.3 and 1.4GHz, since that's a range that all CPUs are designed to overtake (max 200MHz range ).
mine's been oc'ed, uv'ed pretty much within the week I bought the phone in june.
I've got it set to clock between 500-1600Mhz on demand and I've not had a problem yet. Mind you, not many tasks you do on the phone will actually require 1600Mhz and my phone's CPU clocks mostly between 500-800Mhz.
Playing some games or doing quick video conversion will push to 1600Mhz but I rarely play games on my phone and video conversion is short process - burst of 90 seconds to 120 seconds at most. So I think you should be alright so long as you don't leave your phone CPU at 1600Mhz at all times.
Like you said, it is the cooling and ventilation system on the phone, which you can't modify.. Unlike PCs, where you can install bigger fans or water cooling systems. So if the phone isn't constantly cooking itself inside, should be alright.
You should already know that OCing anything is dangerous since you overclock PCs,so I'll skip that part.
Well,if it's dangerous for the phone...It depends.Yes,the processor will die sooner.Yes,you risk frying your device.No,you don't have to push it to the limit(don't push it more that 1450μV,that's the general advice for 45nm chips).However,my thoughts are:
-I won't still have the device when it's time for its CPU to get fried,so I don't actually care.
-Something else,probably the Amoled screen,will make the phone useless by breaking sooner than the CPU will.
-This winter here is really cold(for our standards anyway),so heating has been taken care of.During hotter weather,I kept multiple temperature profiles in SetCPU,so that frequencies get lower as temperatures get higher.
In the end,what matters most to me is to have the experience I want.And with OCing my phone I get it.I'm happy with it,that's all I wanted.So,it's personal preference.Some feel they don't need it,others feel they do.Decide for yourself,that's the best advice.
PS:In case you are using Siyah kernel or CF-Root with Tegrak overclock,try lowering your clock by small steps(8Mhz is the smallest step) for a sane voltage,say 1400μV.Sometimes small increments make big differences.
Thanks for the advice guys. Appreciated.

Don´t oc sgs2.
I got my mobo fried without oc.
Service center replaced everything else but housing and screen.
I used it 2-3 hours in a row, installed programs and put it in charger.
In the morning, it was completely dead.
Overheated because of the use and charging.
So think about twice before using oc 24/7.

I bet you didn't know there are faulty products out there that show their faults during intensive usage,eh?Mine's running at 1.6GHz(give or take a few MHz ) for months.I've played games while charging countless times.And my phone is still here,intact,so that I can write this here.

Of course my sgs mobo could have been faulty.
When the mobo fried it was hot, i mean hot.
I didn´t look temperatures.
It didn´t wake up even using jig.
I sended it to service.
If they had succesfully woke it up, they wouldn´t fix it on warranty (rooted).
Normally oc would be fine because it´s using powersave and underclock it.
But if you play like 2 hours on 1,6Ghz it can get too hot (over 60c on cpu).
I can´t recommend that kind of temperature.
And nobody here knows what kind of vrm´s phone has.
Also cooling plates are not designed for massive oc/voltage.
Of course temperature depends on voltage more than the clock speeds.
It´s up to user if he want to use it that kind of voltages/speeds.
I would´t use it 1600Mhz/24/7.
Generally i know what i´m talking about (using water on pc...)
Just look for temperatures and don´t give too much voltage (as low as possible).
Of course you don´t know safe voltage limits, but try and look what other have been using.
Don´t oc much if you don´t know what are you doing.
@tolis626 Hi, I have oc'd to 1.4ghz for the last few weeks, and I have under volted it to 12.75mV, the same as you, have you had any problems at that voltage? Also, is your 1200mhz voltage stable as it seems very low, to say that it was, at stock, 13mV. Furthermore, have you ever tried to under volt 1600mhz please?

Well,since 1400MHz and 1600MHz aren't stock clocks,you don't actually undervolt them.You rather choose a voltage for them as there isn't a standard one.
My phone is stable with the voltages in my sig(I've only changed 200Mhz and 500MHz voltages a little but too bored to update my sig ) for months,so yeah,I'd say I don't have any problems.This doesn't mean that no one will.Your phone might need 1325μV or 1225μV for 1400MHz.Every phone's CPU is unique in its own way.
@tolis626 Thanks very much, one more stupid question please, will under volting from stock Samsung voltages, even if it's stable, decrease performance compared to stock voltages on an average exynos processor please, aslo will undervolting from original kernel clock speed increase the processors life span? I have researching this and came up with nothing.
Will it break your phone? Not directly. It will shorten the lifetime.
Besides that the heat can indirectly kill your device.
I'm just curious:
Why overclocking the device? I have mine underclocked to 1 GHz max. It still has enough power to handle everything.

No,undervolting will in fact prolong your processor's lifetime,albeit negligibly,because with less voltage less heat is generated.It's plain physics.
Overclocking on the other hand will reduce your CPU's lifetime.The damage(mostly electromigration) is dependent on the CPU and how much you overclock.Quite frankly again,you won't still have the phone when enough damage is done for it to break.If the slightly lower battery life doesn't bother you that much,I say go for it.

Thank you very much for all your help I tried undervolting 1200mhz more, I got to 1075mv and it was rock stable, I don't think I am going to try anything lower than that. Just for info, I'm on SiyahKernel v2.6.2 Thanks again
CPUs care a lot about voltage and don't give a rip about MHz except for the minor heat increase. The chip in my phone is a bad clocker though. If I could get 1400mhz to work at close to the stock 1200mhz voltage I would do it in a heartbeat. Sadly mine requires a healthy bump so I abstain. At least until I can afford to replace it
Number one rule of overclocking, don't push the voltage if you can't afford to replace it
I discussed the topic of overclocking processors with a friend of mine who design cellphone CPUs. He told me that over the lifetime of a CPU, the insulating oxide layers break down. This process is considerably faster at 40% extra power and frequency. So don't expect it to last as long as a normally clocked CPU. So the question is how long it would normally last.

Phone really heats up when I play MC3/GTA III for around 10-15 minutes

Hey all,
I've been noticing over the past few times I've been playing GTAIII and MC3 that the internal temp of my phone rises drastically, to a point where I can barely hold one side of my phone without having to let go every few seconds because it is so hot. From where the battery is positioned, I assumed it might be the GPU heating up, but other att gsII users said their batteries were heating up.
So,
1) Is anyone else experiencing these problems
2) If you are, has anything happened to your phone
I'm debating whether to trade it in for a new one, because I'm still under warranty.
Welcome to high performance electronics. If you push the CPU/GPU hard it's gonna heat up. It's like a desktop, if you do something CPU/GPU intensive it'll heat up. It's a simple byproduct of inefficiency.
As to batteries heating up, that could just be because they're close to the CPU/GPU. Batteries will warm up under high current draw as well.
Do you have a case on your phone? Those tend to trap heat in as well.

If your phone is overclocked, the processor will be running at the max clock you have set while playing the game, which is higher than what it's supposed to be running at, i.e., the stock clock. Prolonged usage at this higher-than-normal clock will generate excessive heat.
Sent from my SGS II.
Yeah I don't play GTA3 anymore because of this kind of stuff. It doesn't get to the point where I have to literally move my hands because of the heat though. I simply don't like my phone getting even remotely warm. I'm just really anal about stuff like that. I fear that doing it will shorten the life of the device and I love this phone way too much to let that happen.
I'm sure it's designed to run at these higher temps since mine is completely stock with regards to cpu speed and voltage. If I can't play a game due to this, then I simply pass on the game. Same with my computer but I digress...
Download an app to check the temperature. Yes, ideally cooler the better, but the phone is designed to handle a certain amount of heat.
From what the op is describing, that is definitely too hot. Over time the components life can be shortened. But what you'll see first is your battery life going down, even quit working all together.
Underclock the processor. That can help keep the heat down. Even as low as 500mhz can pay many games. 800mhz should be plenty for most high end games.

I'm not overclocked, but yeah, same thing happens with me when I play MC3. I got scaredish since it got a bit too hot, seemed more hot than it was supposed to be.
download the diagnosis app and set it to check your batt temperature, if that gets above 45c I would be worried and think about underclocking/undervolting.
As long as your phone is cool enough to handle, don't worry. There's a lot more to it, but the electronics can take a lot more than most people credit them for. The battery is the most sensitive to temp, but so long as it's not for terribly long periods of time, you shouldn't even notice any additional degradation over the long run.

Average day to day operating temps are between 30° and 40° celsius.

If anyone's interested, I have pretty much eradicated the heat problem while also boosting battery life and conserving performance. This was done through setCpu: http://forum.xda-developers.com/showthread.php?t=505419
The problem was that apps were just running the processor like crazy on the 1.2 GHz speed setting, and it used a considerable amount of juice that was unnecessary, heating up the battery to a ridiculous amount.
But anyway, here's the profiles/voltage settings I use:
Main Governor: 200 MHz - 1200 MHz on demand
Profiles:
- Charging, 800 max, 200 min, ondemand, priority = 100
- Temp > 44.1 Celsius, 500 max, 200 min, conservative, priority = 100
(this is a conservative temperature, but most place the *dangerous* amount of heat at 50 degrees before battery life starts decreasing, the CPU/GPU components have solder that melts at 70 degrees)
-Screen Off, 500 max, 200 min, conservative, priority = 75
-Battery <25%, 800 max, 200 min, powersave, priority = 75
-In Call, 800 max, 200 min, conservative, priority = 50
Voltages:
(I was able to undervolt by 50-75 mV for each and still remain stable, these are tested btw)
1600 MHz - 1400 mV
1400 MHz - 1225 mV
1200 MHz - 1200 mV
1000 MHz - 1100 mV
800 MHz - 1025 mV
500 MHz - 950 mV
200 MHz - 875 mV
and that's it! It's working great, I don't have the heat issues I used to, now I can play graphically demanding games and the temp doesn't rise past ~42 degrees, pretty solid improvement. I also get 24-28 hours of battery life with 2-2.5 hours of screen on time per day.
No need to worry about this. That's nowaday phones designed to be. Just normal heat.

I agree that's how they're 'supposed' to be. But things mess up. AMD processors are designed to handle heat, but they are still known for getting too hot and damaging the graphics chip. Better safe than sorry.

Agreed. theory and actuality are two incredibly different concepts

Safe overclocking temps SGP5

I have my SGP5 overclocked to 1.5ghz at the moment via Tegrak. Everything is running smoothly but the spot on the back where the CPU is gets warm to the touch. Not hot or anything, but obviously warm.
Before I had it overclocked to 1.45ghz and it stayed a lot cooler, but to get to 1.5 I had to bump the core voltage to 1.35v. I also have the up-threshold set to 35% so it spends a good amount of time at max speed.
Since these things don't have CPU temp monitoring, how do you tell when it's too hot? My battery temp never goes much over 80*F, so that doesn't seem like a good indicator of anything.
Sitting here playing music with Mufin my IR temp gun reads a max of 100*F on the back of the case over the CPU. Battery temp is reading 77*. Is that too warm? How much of a temp differential can there be between the outside of the case and the CPU itself?
I'm no noob to overclocking PCs, but this is my first Android device so I don't really know it's limits as clearly.
Any help would be mucho appreciated!
DISCLAIMER - anything within this thread has the potential to do permanent damage.. I haven't had any issues yet but will not be held responsible for any damage!
So I just pulled the back cover off it. Running the same program for 10-15mins the CPU never exceeded 82.5*F which is well within safe limits imo.
I guess that goes to show how poor the cooling is in one of these things with the back cover on. I'm going to keep running 1.5ghz and report any issues. The difference in smoothness between 1.4 and 1.5ghz is pretty dramatic.. web browsing is very very smooth now. I probably won't be going any higher than 1.5, but for now it seems safe.

Just tried your profile, and I have to say it works fantastic! The web browsing really is super fast.
Is there any major danger at this clock speed with On-Demand on? I mean, it'll only use 1.5GHz if it needs it right?

Ondemand from my understanding, scales processor speed using the values in the up/down (I believe System Tuner refers to down as "powersave bias") threshold. From my experience it's the best governor to use as far as customizing it easily and getting it to respond well.
Whatever you set the up-threshold to, when CPU load exceeds that value it bumps the speed up to the next "level" and ending in full speed. Then when CPU load falls below the down-threshold, it scales it back down to the next lowest level, so on and so-forth. You can also adjust the sampling rate too - lower frequency means it checks the CPU load more frequently and essentially makes the governor more responsive.
When I set mine to 35%, almost any program aside from stuff sitting almost completely idle will trip the CPU to hit 1.5ghz. This makes everything real responsive and may use more battery.. but I prefer having a more responsive device. You can also adjust the up-threshold to a higher number to try to lower temps and extend battery life. You can really play around with it to suit your needs, there's not really anything to screw up there.
There shouldn't be any danger using it with the ondemand.. but since I haven't tested this for more than a few days right now just keep an eye on temps (especially while playing games) and watch out for any "stuttering" out of the blue. Mine gets warm but nothing excessive. You'll be able to feel it on the back between the speakers.
I have to say though, even running such a high clock speed I'm not really seeing any negative effect on battery life so far.
Lemme know how yours goes!
How can it not have any risks? When the heat is too much somethig will explode wouldn't it?
No just kidding, but seriously. There is a risk of overheating a hardware and 'destroying' it, there should be!

Well of course there's always some risk in overclocking! Especially when you don't know what you're doing.
As far as using one governor or another though.. when it comes down to it there shouldn't be a huge difference.

I use SetCPU for root, but i don't see an option for more than 1200 mhz. How can I get it to 1500?

Heating when playing light games for 10 minutes... normal?

I got my OPX yesterday, and I love it. Battery life is good, I have SOT of 3 hours and still 43% left.
However, when playing light games, it reaches 60°C very quickly. For example Minecraft PE with low render distance.
My GPU is underclocked to max 330mhz, my CPU is not underclocked but undervolted (-75mv). Using blu.spark kernel on Oxygen 2.2.1.
The battery is draining a lot faster when playing as well.
Is this normal?
Edit: It's much better with CPU limited to 1.2GHz. But a bit laggy.
With 1.2GHz is only goes up to 49°C.
I would manually set voltages until they're the lowest you can go. I've never had mine heat up and I run emulators. You should be able to bring your max clock speed to around 980mv or so which for me has never produced heat. I have my phone over clocked to 2.57ghz and I've never had any problems with heat.

If you ever decide to switch to Boeffla I have a profile called Swell that I work on and have published. Haven't used Blu Spark since I started using Boeffla when it was released
