What temperatures are acceptable for overclocking?

My sensation is currently overclocked at 1.73ghz, and according to a temperature widget I have it seems to hover between 25-45 degrees. I can only find the one temperature reading, so I think this will be the battery temp. I've set setCPU up to run at 1.73ghz below 35 degrees, then come down to 1.5ghz above it. If it gets to 50 degrees, it's then set to drop to absolute minimum and play a warning sound. I've also set it to drop to minimum when the screen is off to save power if the phone doesn't sleep, and to not exceed 1.2ghz when on charge or during a call. None of them are fixed, they're set to intellidemand or whatever it's called.
Do these settings sound reasonable? What sort of temps would be deemed as normal? I don't want to shorten the life of the phone if I can help it.
Also, if this temperature reading is just for the battery, what would I need to monitor CPU temperature too? Is there an app available so I can actually log the temps to see what happens when playing games, etc?

System tuner pro shows CPU temperature and does logs.

Cheers, I'll give it a try.
What sort of temperatures are acceptable before I risk the CPU's lifespan?

Why do you need these over clock speeds? They will only ultimately increase temp, burn excessive battery and reduce the life span of your device.
Use common sense, these speeds are only worth using for bench mark tests
Personally anything above 43 is to hot for my device, although not same as yours, you can use set CPU to throttle down at this temp

I mainly wanted to overclock since the normal sensation was underclocked in the first place, the sensation xe runs at 1.5ghz and the CPU is the same. So I wanted at least that. What I'm wanting to do now is find how quick it can be before it starts running too hot. Just wondering what's considered too hot in the first place.

My web browsing is much better (faster and smoother) at higher clockspeeds and performance governor. So that's why I run higher speeds. I use my phone for internet stuff more than anything else.

Mine seemed smoother too, for normal use and for my emulators. I found a problem though, setCPU wouldn't let the phone sleep so my battery went from 85% to dead overnight! It also seemed a little unstable even when turned back down to 1.53ghz, so I've uninstalled it and it's now running 1.53ghz just from the kernel. Runs perfectly now and battery life is back to normal. No noticeable difference in performance going from 1.73ghz down to 1.53ghz either, but now the battery temp seems to top out at 35-40 degrees or so, so about 5-10 degrees less than when it was set higher. I'll still give that app a go though so it can monitor and log temps while I'm playing games, etc.

Insane CPU temperatures

Hey guys,
I am calibrating my battery atm and as you may know you have to discharge your device fully to calibrate the battery properly. To speed up the process I decided to install a stresstest app to my phone and guess what: the phone gets insanely hot, I can't even hold it in my hand longer then 5-10 seconds. Kernel tuner displays me temperatures between 78 and 82°C.
But this overheating problem not only happens with the stresstest. When I start watching videos on youtube or start using my phone for maps it gets hot too (about 60-70°C). It starts to bug me.
What do you guys think I should do to fix this? I already thought about applying some thermal compound between the CPU and the metal shield around it. But I'm not quite sure if it's a good idea. I already have a new phone but I still need two phones because I have to travel between Germany and Switzerland all the time. And this issue starts to make my Sensation unusable.

I would suggest an anker battery. It has a greater capacity and it keeps the battery very cool.

Already using it and I'm talking about the CPU temperatures and not the battery's temperature.
And sure I did try different kernels. Even at stock kernel setting this thing gets hot as f***!
Send from my hovering Note 2

So I just decided to disassemble my Sensation and put some thermal compound on the processor chip. Now I'm not getting over 70°C at full load, 1,56GHz. Pretty good outcome. And under normal use it doesn't heat up over 45°C.
I really have to recommend you this method!

Hello guys,
Guys post your battery temp during normal use,gaming,heavy app use plz..m facing heating issues and want to compare with other Xperia L's

This is during my normal use with 3G which heats upto 40 sometimes

I cannot said what the temperature is when I use 3G as my data package is out for this month already, but I think the temperatures provided by you are normal. Like when you are playing Fifa the CPU is cooler than mine. I think they are normal. Most of modern phone's have heating issue during playing.

Well, don't think so. My phone also heats up during charging when I use it. I'm not sure if this work or not but you of course when you wan't can enable option that Nexus 4 has. It's like when a phone reach certain temperature a cpu/gpu clock is lower to prevent battery overheated.
I don't have it enable as mostly I don't play or do anything more stressful that will make phone hot.

dude you have a fit right...oh you sold it, still that device was about half as powerful okay 1/3 rd yet the battery temp with 0 activity and mostly in deep sleep is at 30 C.
now xperia L is way more powerful so should get a tad bit hotter too right(of course that's based on CPU activity) try it put is down for say two hours no charging , no nothing so that in deep sleep(lowest freq) also no 3g(that has its own daemon that eats cpu power i.e. causes cpu to work and hence battery drain and heat). wifi is okay(stable connection hence minimal cpu usage as no reconnections).
now check yor battery temp should be around 35C so your device is fine.
all this is based on stock heat and power management cant comment on custom kernels.

if you are on a custom kernel the best practice is to uv and NOT oc also change the governor to Interactive since thats far better than performance.(spimply put performance goes to top cpu freq even when not required and slowly scales down while interactive scales up fast and down fast at user touch events) for heating and basic phone wear and tear purposes.
and one of the main reason along with more ram(i mean lower bloat hence more free ram) that i want a cyanogen mod ROM.

Before and after playing candy crush.lol
When charging,it will up to 37-39 degrees

Qualcomm makes the MSM8230 chip that you see in L, there are 4 different "types" based on how it meets their quality standards. These are Slow, Nominal and Fast (Faster is on Higher end chips like APQ8064). The main difference IIRC between these types is how stable each can handle undervolting. CPUs that are "Fast" for example come pre-configured at a lower nominal voltage than a "Nominal" type CPU, and more so than a "Slow" type. IIRC, there's like only a -50mV difference between Fast and Slow out of the box, however Fast CPUs should be able to handle lower voltages than Slow-type.
This may explain why some people complain higher temp than others on account of same tasks. Although there can be other reasons. I'm not quite sure.
To find out what binned CPU you have, I recommend the following:
YOU MUST BE ROOTED! And installed busybox
1) Install Terminal Emulator
2) Reboot your phone
3) Open Terminal Emulator, and type:
su
dmesg | grep PVS
(if you don't see anything, try it.immediately after fresh reboot)
For example I've fast binned cpu

So basically, far as I understand I got Fast CPU which isn't going to be as hot as the Slow type due to lower voltage ?

then go for ondemand the performance might be a tad bit slower than preformance governor but your battery life should be better along with the heating...also no oc.

That doesn't tell us anything. Get an actual battery temperature reading, not what you think it feels like. Most kernel apps should tell you.

I don't pay attention to it myself since I know it isn't overheating. Various kernel apps should give you a reading, hell even Antutu Benchmark tells you your battery temperature in Device Info.
Also, when your battery reaches 60C (or 65C, forgot which of the two), your phone will force shut itself off. Chances are, you're not even feeling much heat from the battery, the CPU usually produces more heat before the battery can even reach that high (some kernels have battery shutdown disabled anyways). The CPU starts throttling at around 60C CPU temp (NOT battery temp), and force shuts down at 105C. Clearly, "warm" is no issue at all.

Galaxy s6 throttling as hell

Since I bought my gs6 I have noticed the soc temp heat up very quickly and couse a massive throttling of the gpu above all ...so that performances go down of 50% expecially when running antutu ...is that normal or should i send back my phone to warranty

every CPU throttles, the S810 throttles even more, they have to, and don't run benchmarks, they won't do you any good, if in day to day usage the phone heats up it's normal, my S6 do heat up but i never noticed throttling, i never noticed lag when it becomes hot.....try to use your phone normally without ****ty benchmarks...

Thanks for your answer
Yes I know benchmarks are quite worthless ..but it's not just about that..i notice this even while gaming ,browsing and even doing light stuff ..its however pretty much annoying

i don't play games that much, i only play couple of games like boom beach, i don't know if this game considered heavy or light, but if i play it for about half an hour the phone heats up a bit but it doesn't lag at all....in light usage usually it doesn't heat up, but even if it heats up i never notice lag, the phone stutters in some places but no lag.....

Hi,
Please install the app called CPU-Z to check your device temperature. Also keep in mind that depending on where you live, it's easier to heat up than on other regions, as the external temperature does make a difference.
To throttle it needs to get very hot. Check if you have Mobile Data and Location turned on when not needed, and specially Mobile data when you're out of range, they consume lots of power and heats the device up considerably. Also, Wifi if not connected will keep searching for somewhere to connect and consequently will use your device power and heat up.
Another thing to keep an eye on is background apps and the external temperature as mentioned before. On S4 I faced a serious battery drain and overheat problem due to background apps not letting it sleep.
All the best,

Already have cpu z on it
The temps get up to 80 degrees celsius when under really heavy usage ..of course this temp refers to cpu not to battery that stays always around 33 and 37 degrees
P.s i dont notice lag either. .even when performance decrease its good enough..i was only qondering wether it is normal or not

You may have a lemon S6. Return your S6 to Samsung for warranty replacement.

And here's one of my device after running AnTuTu benchmark:

I noticed that during the benchmark it got to the 80 degrees range, but it lasted a few seconds, if your device get to 80 degrees and stay at it, maybe it isn't dissipating hear correctly.

80 sounds crazy not a bit high

80 its high but device can reach that temp sometimes. Example if you play and fast charge same time it can get that temp. And not to forget outside real temp. Here its so hot... up to 40degrees

Hi All,
80 degrees is not as extremely as you might think. People tend to think its too crazy or high because they never would have seen it and the most times they check their cpu temps on CPU-Z it will be hovering around 40-50 degrees. The best way to check your temps in S6 is to open CPU-Z/AIDA64, have it minimised in a smaller window and drag it to the very corner of one side, while this is running, open a game like dead trigger/skyforce and notice the temps. Also, do the same while performing an antutu test. Yes, the scores will be greatly reduced and the temps will be a tiny bit higher because of this smaller window running simultaneously, but you can compare your temps pretty easily. Also, try to be present in a ambient temp of 26 degrees rather than upwards of 30 for a fair comparison with fellow users. According to me, 80 comes up at times but it lasts only for seconds (S6 starts throttling exactly at 80 and beyond that the core clocks gets aggressive reductions) but it will never be constand even while running a game. Mine CPU idles @35 degrees with ambient temp being 26-30.
My temps : (All temps in Celsius)
Ambient temperature 26 - 30 degrees :
Battery temp : 25-30 degrees
Idle : 32-35 degrees
Slight tasks (Whatsapp, checking notifications) : 37-39 degrees
Multiple applications : 38-43 degrees
Game - hungry shark evolution : 47-52 degrees
Game - Dead Trigger : 55-62 degrees.
Ambient temperature 31-36 degrees :
Battery temp : 33-37 degrees
Idle : 41-44 degrees
Slight tasks (Whatsapp, checking notifications) : 46-50 degrees
Multiple applications : 47-55 degrees
Game - hungry shark evolution : 55 degrees
Game - Dead Trigger : 65-70 degrees.
Also i've noticed that the CPU temps increase for a flash second to 65 above while installing multiple apps from playstore. Try updating/installing multiple apps from playstore, have the CPU-Z open, and exactly while the app finishes downloading and starts installing, there will be sudden spikes in temperatire depending on your ambient conditions. But, never reaches high temps constantly.

all right, thank you all guys for your replies. So..i sent my phone back to samsung and got a new one 2 days ago,i can definitely confirm that the phone heats up exactly like the previous one , maybe just slightly less(i mean 3 degrees..nothing craze).
For anyone suffering of this ''issue", notice that temps may drastically change depending on wheater temperature ,humidity, etc. if weather is at 40 degrees ur phone wont surely get to a lower temp.
BTW it s clear that this phone heats up and throttles ,some may notice that others not, so unless you receive overheating warnings or have other serious stuffs on ur device ,do not exchange it for a new one because certainly it ll be quite the same as the previous one. Oh it 's quite clear as well that folks claiming their device doesn't exceed 60 degrees under heavy usage either are liers or super lucky ones with uber super powerful units...think its more probably the first option.
regards ^^
