Is there a good phone out there that is able to not heat up so badly compared to other phones when playing games? like maybe in playing a game phone A heats up to 40°C but phone B only heats up to 30°C, something like that, a good performance to heat generation ratio?
Been using my current phone(Galaxy SII, I9100) to play Drastic DS emulator but 5min in and my phone is like burning and maybe even damaging my phone, i never overclock my phone though, underclocking to 800ghz also is useless
Right now im only playing it on my bus ride to school since the bus is always very cold (you know a bus is very cold when your playing games and your phone is suppose to overheat and keep you warm but its not OVERHEATING)

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...

Yeah...sounds way too hot to me

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.

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

I know, the Tegra K1 gets hot. Is this a widespread issue though (some people only report minor warmth)? How hot is too hot? Mine is getting stoopid hot, and I'm pissed because I finally have a unit with almost no issues, save the over heating problem. I know the SHIELD has issues with screen cracking, and the N9 should be safer with the metal band, but something doesn't seem right...

This.
combine that with a badly configured cpu governor that boosts the frequencies to 2+ ghz even for simple tasks that do not need all those cpu cycles.
In addition to the whopping 1.5ghz touchboost frequency (WTF google).
After rooting and fixing the last two points, I experience high temps only when playing games.
Blocking Ads also tremendously helps temps while web browsing.
I wouldn't consider it a problem. I also doubt you have a bad unit even though its getting hot. Chances are if you do the exact same things on 100 nexus 9's the temp will be very close. I've been looking through the kernel code for tegra throttling and doing some tests. The tests show it starts to very lightly throttle starting at 70c in my tests. I believe I saw in the kernel there is 3 throttling states basically, light, heavy, and one other I can't remember. Shutdown occurs at right above 100°c.
As far as the governor, I'm sure if it made sense gooe would have lowered it. But, if I remember right this was part of project butter to make the ui smooth, as well as some other things. I don't think touch boost is killing battery too bad, and I'm willing to sacrifice some for a smoother ui anyway.
Thisbis just a hit running CPU, no way around it and its not a defect, its just a side effect of a powerful CPU in this design. I also noticed although it heats up quick, it cools extrememly fast. Like dropping 15-20° in seconds, literally- so overall I don't think this is a huge problem, but if they can make it better, more power to them.

im really happy to hear about your thought
but if the heat issue occurs many times, will it break the others hardware,
i have seen in laptop, if the graphics card heat too much, it can melt the motherboard and the others parts of the laptop,
im afraid that it will happen to this tablet eventually
i really love my nexus 9, just this heat issue make me incomfortable
This tablet is the same as the shield tablet how come it play games so badly if this can begin what’s the best custom rom and Kerman to play games on?
It overheats and throttles. The Tegra K1 in this tablet is not the same as the one in the Shield tablet. Same GPU, much different CPU. This one gets hotter. It really is too hot for a fanless tablet if you try to run it at full utilization for a long period of time, as a game will.
You can try underclocking the CPU. That will probably make it perform better for games because the GPU will run faster.
Actually it's not really "overheating" exactly. It has a temperature limit and once it hits that temp, it slows down the CPU and GPU to stay under that temp. It's a power limit. It uses too much power to run at full speed continuously for a long period of time in a tablet.
I'm using Slimrom with Fire Ice Kernel.
PUBG runs pretty well using gfxtools with low setting + 30fps.
But the game began to lag after 15min due to thermal throttle.
Will try the heatsink mod later and hopefully able to improve the performance...
