Please help..I am really getting hopless and disappointed at this phone..I am using lite'ning rom and before that the original rom i am still experiencing extreme overheating when playing games like Asphalt, What am I supposed to do what's wrong?
i'd really appreciate if someone could help.
Are you charging at the same time?
What is the surrounding air temp?
Are you overclocking?
Have you tried a different kernel?
Have you tried another battery?
I would expect it to get quite hot playing games like that for an extensive time,.....
How long?
What is your actual battery temp?

Where did you get ashphalt from? the reason i ask is because i think i saw it in the samsung apps store as S1 only.
And how hot is it actually getting?
Are you charging while playing?
Thank you all for your concern. I am not charging. Original battery with temp around 39'c. No change to the rom (lite'ning). Will changing the kernel resolve the problem? Games are all from Gameloft fir GS2. The phone gets really hot that I can not hold it!!!!
Isn't Asphalt just one of those games that doesnt fully support the dual-core cpu? I think it is the same problem with Gangstar:Miami Vacation. The game runs both cores at 100% which makes your SGS2 VERY hot.
I'd advice not to play any of those games, that are not updated for dual-core CPUs
I had the same problem mate with lite'ning/stock rom 2.3.3. Changed rom to Batista70 and heat issues deduced significantly, also changed kernel. Try changing both custom rom & kernel to find best combo for your phone use.

I had this issue while playing "Medieval Castle Defense", but not on "Asphalt".
Too much undervolting especially on the higher frequencies can cause overheating while running resource hungry app and games. [Says Tegrak himself! ]
If 39 degree is what you call too hot, my battery sometimes reaches that temp while surfing using hspa.
I experienced the same temps a while ago playing Asphalt 6 but i changed the settings SETCPU and from then on I have only top temps at about 40 maximum.

I just noticed that under heavy use such as decoding mkv the phone can get a bit hot. Especially in the upper part of the display under the samsung logo.
Anyone else experience this?

My SGS2 gets fairly hot when the CPU is busy on the backside right below the Camera, which is pretty much in the same place, just on the backside instead of frontside.
I'd say its normal behavior. I've noticed it is especially bad with applications or games, that use a lot of CPU cycles.
Being as powerful as it is, i wouldn't be surprised if the SGS2 uses up more power when the CPU is active then older phones. Power usage for doing the same amount of work should be lower then older phones. However some applications don't limit their CPU usage, and therefore you may end up using more power (phone getting hotter) then you would on older phones.
Well it is after all one of the thinnest and most powerful smartphones on the market.
Power = Heat
Thin = Little cooling space = Heat
Heat + Heat = Much heat
No way it's overheating though. I think that would be possible if you overclocked it but I'm fairly sure they've tested it for overheating with stock frequencies and voltages. If you read the manual it probably says that you're not supposed to use it for long periods of time in direct sunlight to prevent overheating, just like it says in almost every phone manual. At least iPhone shuts itself down if it gets too hot and I wouldn't be surprised if modern Android phones did that too.
Hi, I'm no expert, but 70°C is quite a lot, isn't it?
And I was only browsing market...

You said it yourself, "Heavy use", the S2 is just a handset after all, not PC with liquid cooling or something.
The CPU produces a lot of heat, it's a powerful CPU, the device is thin, so:
powerful hot CPU + thin choking case + long time heavy use + your warm hands all over the device playing games and surfing the web etc = very hot device.
Try maybe to change the kernel !
Not sure if it's normal but once my phone went up to 53 degrees c while charging. I unplugged it and waited, it went back to charging at 46 degrees c.

I've recently purchased carcassonne from the market and while I love the game, it does seem to eat up the battery pretty quickly. So i'm wondering if its just me or are other folks experiencing this too?
Bit of background, i'm running Cognition 1.51 on an sgs2 and while playing the game it looks like it consumes around 58% (average) cpu. This to me seems excessively high. Carcassonne for those that are not aware of it is a tile based board game, which doesn't seem to me to be a candidate for a fast cpu. Yep, i could understand that the AI might require CPU but surely not for the rest of teh game.
So question is, does anybody else have the game and do you notice high cpu usage on it?
I didn't play that game but 58% consumption after how long playing? Do keep in mind that a playing a game is CPU intensive task, so CPU will be hot and battery will drain much faster than other stuffs.
Regards.
Ordinarily yes I'd agree about games and CPU usage. But for this type of game I'd expect it to have very minimal requirements.
Also I started up a fresh game and left it waiting for me to play my turn. Leaving it waiting for twenty mins and when i checked utilization it was still 30%. Given that there was no animations or screen activity that does seem excessively high.
Am trying out miui rom now to see if that makes any difference.

Okay so i've Noticed that recently on ics roms that when web browsing or playing games my neo gets really hot. I expected this as it has a lot to process but today whilst web browsing it got so hot that i couldent hold it anymore and it started making a burning smell. (this is without overclock min: 242 Max: 1024) i super quickly took out the battery and left it outside for a bit and it seems okay now but i was woundering why it keeps getting so hot on ics roms, as i dosent over heat on gingbread even with over clock!
Is it to do with Hardware Acceleration?
Same issue here although it never reached the burning smell! . Does any1 know the reason?

Burning smell is not a good sign,suggest you to move back to gingerbread as a precaution mate.
>>Is it to do with Hardware Acceleration?
can be,without debugging much cannot be told I guess.

Glad it's not just me then, Yeah the burning smell was after a few hours of browsing and playing fruit ninja.
me too annoying when your in the middle of somthing then your neo heats like theres no tommorrow =.=
I tried turning off "force gpu rendering" but still same heat ??? im very confuzzled.
same here, and i did a quick remove and back to .62
Neo gets Really Hot when playing games and surfing internet
The heat is too much that My hand can't stand it :'(
this is very unpleasant and really annoying.
Each time I play a game I have to take of the cover and its kinda help somehow but still it gets too much hotter.
most of the time its temperature raise more than 40 C*
any solution for this problem?
After 40-50 minutes in Modern Combat 3 multiplayer,my phone was very hot,but i think its normal,other games,programs make the phone only a little hot....
You mentioned "overclocking" ... and that's the most likely cause of overheating right there ... in your place i'd try to set the clocks back to factory defaults and use the phone then, i'm using Neo MT15i(currently with Cyanogen mod 7.2.0 RC1) and never had overheating issues

I get the same heat with underclocking @800mhz
and i dont get heat on gingerbread, only ics. in fact i overclock without heat on stock gingerbread using nightelf kernel.
Have the same problem with ka09 + pwa ics kernel 1.0 .Neo is abnormally hot compared to cm7.2 109 + nightelf lite 3.3.Could it be because the rom as a whole s still in beta stage ? And to clarify im not using oc just stock speeds.

This seems too big and too common of a problem for sony to leave. im sure it wont be happening in final ics release.
I hope that its only a nasty bug in the beta rom .The strange thing is that not many have noticed it so im wondering if it apperas only to some devices. Btw the ics roms cant be compared with the gb ones .Its like the day and night
Heating of smartphone is normal, especially when you oc your cpu...
When I'm playing eg. mc3, 9mm or gta3 with [email protected],4GHz after tens of minutes my phone is warm, but not really hot.

Yes i know but the thing is even with the oc 1.4 on cm7.2 rom it doesnt heat as much as the 1024mhz on ics.Anyway i hope its fixed inthe final version .
playing heavy games will no doubt heat ur phone...i think it is the beta rom bug...also...i have noticed that when i browse internet in 3G mode...the phone really heats up if it is not receiving good signal strength...mine heats up even on stock rom without OC.
i got heat on gb rom too ( @1024mhz max) playing nova 2 D:

SOLVED
SOLVED: (i think)
been doing some research into kernel governors and found out that the current "ondemmad" governor has a really fast ram up to high clock speeds. Whereas governors such as Smartass have a slow ramp up.
I believe this is the cause of our heat problems as when using Night elfs kernel with smartassv2 governor i played 3 hours of games (nova 2, fruit ninja, defender II) and neo got warm but not hot atal.
I also check cpu spy and despite the different governor the both reached speeds above 800Mhz.
SO i guess the fast ramp up in the ondemmand governor cause heat then?
So why not test with governors that have slow ramp up and tell me if heat gone
In gb roms with fxp kernel ,clocked to 1024 with ondemand when playing heavy games like e.warriors the phone get a little warm but cant say too hot.The problem is that in ics rom it gets warm just by having the display on (ondemand,1024 speed).When i will flash again a beta ics i will post that if changing to smartass has an effect in temp.
First off is this a good idea? can such small devices be over clocked in a safe way without risking damaging the hardware?
if yes which would you say was the best app for doing so?
Hi,
A good idea... maybe, maybe not... it depends on what you want... higher scores in bench?A shorter battery life?A very very hot device while browsing or gaming (if you run at 1.8Ghz for example)?A little extra power for some apps/games?
With overclocking a little (1.5/1.6Ghz) I noticied that some apps open a little faster and the genera UI is a little more responsive...
There is always a (little) risk to overclock our phones, generally due to overheat but also some CPU's can't handle high overclock.
For me I don't remember reading someone burn her CPU with overclocking but...
There are still some software protections before to burn a CPU (thermal throttling, CPU temp limit before shutdown, etc...).
Obiously the duration of life could be reduced mainly if you always run at 1.8Ghz with playing games... So the "safe" way would be no overclock or a little overclock like 1.5Ghz... For you to test and decide...
For the apps: SetCpu, System Tuner... there is a bunch on the Play Store.Just for the CPU settings I would say SetCpu.
For me i will never overclock my cpu. Just install siyah kernel and it's pretty smooth in games. Overclocking will damage your cpu and maybe loose some of the performance.
I can't see the need on this device, I might experiment with uv, maybe even underclocking, but as above, super smooth on siyah, and Slim Rom

Talking about battery life i installed darkys rom 3 onto my i9300 and the battery life is already suffering a loss of maybe around 25%. In saying that over clocking will only cause me to lose even more so ill leave it for now

Overclocking won't damage your CPU unless you set crazy voltages, or let it overheat. Also, it won't lose performance... that's crazy talk. Only if it overheats will it throttle, but that only happens on large clock rates like 1.8GHz or if you're in a hot environment.
I had my old LG GT540 overclocked with no heat problems mind that was only a 600mhz cpu, had it up to 825mhz.
But we already have a powerful cpu in this phone, foe now I don't see the need to overclock.

The best app depends a lot on your kernel and device. For example, for my Galaxy S2 the best OC was with TegraK Overclock.
With my Xoom CPU Tuner is still the best.
With the S3 I suppose CPU tuner would be alright as well, but I haven't had the urge to OC it, because I find SiyahKernel still quite unstable in the S3.
You need an overclockable kernel in order to OC your phone.
As for damages, it is hard to tell if they are permanent, but picture this: your battery will have to be recharged more often, because it will drain faster. Since batteries have a limited lifespan which depends on how many charge cycles they go through, the more often you discharge/charge them, the shorter their lifespan will be.
Also, there is no telling what kind of ill-effects the added heat can do to the phone. It may be totally harmless, but it may also affect the quality of the display, since the added heat will be right underneath the screen.
The lifespan of the CPU will be shortened: instead of being able to work well for 20 years, it will work well for 18, 17, 15, but more than enough time for us to already have replaced our S3 for organic, intradermal smartphones!
My S3 heats up really fast when playing Clash of Clans... 5-10 min of gameplay.. and the bottom part of the phones gets really hot... somewhere around 50c or more
i can play other much more resource extensive games like brave frontier or Knight and Squires or sometimes watching movies for hours and the phone barely Heats up
btw.. what's on the bottom part of the phone that's causing the heat ? the ARM SoC ?
i kept changing between different ROMS and kernels... but same issue
It's the CPU, your game is probably coded to use all four cores at the same time -others may only use one.

You're right, whoe SoC is at the bottom, you just have to deal with it, i mean, phones don't have coolers
Also, it's way smaller heating than on S2, it's SoC was at the top by the camera, and the camera cover was metal, and when it heated up it could be so hot it just burned and your finger stuck to it, so, be happy, our S3 is 'cooler' than many other phones (atleast what i know).
Cheers.
Ok thanks guys... wow that 50+ c isn't considered hot
so are they any apps that can dynamically adjust clockspeed based on the Apps/games launched ?
No problem with playing game for me also..yea it can get hot sometimes when playing *heavy* games but in general its ok
