Over heat problems

What do you consider an over heat temperature for a phone?
My g2 over clocked @ 1.42ghz reaches 108 max when playing emulators and 3d games, is that consider over heat?

Nope overheat would be like 112 or once your phone turns off its self

So could that be reason for reboots on my previous G2 where temp would reach even 115?
I remember the sidekick lx 09 use to have the overheat problem and sidekicks usually warn you with a thermometer. Sign where the battery sign goes. I once put my phone in the fridge and forgot about it in the and left it there freezing for a good hour, luckily it didn't damage but it had ice flakes all over....

Eh... Well having a phone even over 110 can damage the component within the phone, that's why one my phone even gets near 110 I lower my overclock or even turn it off completely. LOL lucky ur phone didnt get messed up in the freezer.

For a moment I thought that these temperatures are in celsius

"Overheat" for me is when the battery cover becomes very hot to the touch. This has happened to me once.

I bought one of those el cheapo batteries from Ebay and then trashed it when I realized that my phone was no longer reading the temperature correctly.

Off-topic here, what emulators are you running on your phone?

My phone gets uncomforably high when I'm using it overclocked that high while I'm charging. It usually cools down for me after I unplug it, and sometimes I take off my battery cover as the aluminum heats up pretty quick too.

The lid might act as a heat sink... I dunno but just a thought. I set my alarms at 40c

This may sound stupid but is there such thing as under heating a phone or over cooling it? Cuz in the winter phone temp is usually very low even when I play emulators going to college @ the train station

Maybe, it depends on the situation. Very low temperatures will affect the LCD temporarily and maybe cause poor battery efficiency but shouldn't affect the running of the phone too much. If its cold outside, the phone will be able to dissipate the heat more.
Transition between high and low temperatures can significantly affect it though. I think its high temp to low temp, the air will condense and deposit moisture in the phone. Again, its probably nothing to really worry about, its only extreme temperature change that does that normally.

I think cellphones are made with outside temperatures between -10° and +50° C in mind.

Hardware Temperature Regulation on S2 and Related Concerns

This is weird. I know a lot of users were complaining of heating issues with their SG2's. I can't complain with the current S2 I have on me. The temps never exceed to that extent where it becomes unbearable to touch, and the temps are usually maintained between 29 and 34 degrees Celsius. I heard from a couple of sources that the Blue motherboard fitted into the S2 has a temperature regulation sensor whereas the Green motherboard does not and many complain. whats stranger is that my quadrant benchmark scores never exceed 3400 (on the 2.3.5 firmware) and its really starting to becoming puzzling. Do I have a hardware defect? or is it something coming in the way from preventing me seeing the full potential of my S2?

A quadrant score of 3400 is typical for a stock SGS2.

lol, I forgot I was running a stock version. i guess those users posting up scores greater than 3700 have rooted their devices with some napthalene kernel, thanks for clearing this up for me. I guess im still a noob. is 34 degrees celsius normal?

^^ "napthalene" ?

isn't that the name of the kernel most folks are using? :confused
lol

It is just people aren't used to phones getting warm when they are using an app like a game. They then panic and think their phone is going to die and post about the phone over heating or getting too hot. If you can hold your fingers on it continuously that is warm not hot. Hot is like fresh cup of black coffee which is too hot to hold.

Yeah, and most users also overclock their SGS2. Mine for example does about 3400 when stock, but when overclocked (simple when you have root), will bring it to 3700 and above. I've hit close to 4000 in the past as well.
WIth regards to the temperature, that is the temperature of the battery. 34ºC is normal. It can go higher during charging (I've reached 44ºC), but I recommend not charging and playing a CPU/GPU intensive game at the same time as you would have two heat sources that the phone will have to deal with.

Cpu temp concern

I'm using franco 165 and I undervolted 100 on all steps my cpu hit 50 Celsius or 120f I dropped my phone twice now in the official bumper I have a better case I'm gonna switch to but two part question.
#1 does dropping device damage the cpu mounting causing overheating or stuttering
#2 is the cpu at 120 running hot? It's at 94-96 idle

Another one of these threads.... Holy cow.
Yes the N4 irradiates a good amount of heat and does get quite hot at times. Its totally normal.
If your search you'll find many many many posts of this topic. Some people believe its overheating. I my self think the high temps in this device are normal and haven't caused me any issues even overclocked.

50°C for CPU temp is well within the normal. In fact that is pretty cool.
Mine is currently at 43° and only used for less than 1 minute.
Points for concern are CPU > 80°C
And battery > 50°C
Anything below is nothing to even get concerned with.
I will state the info I have given to others previously.
With defaults the phone will start to throttle at CPU 60°C or battery 48°C, this is what is classed as running warm.
From then you have up until CPU 100°C or battery 60°C before the phone will power off because it's running critically hot and needs to cool to prevent damage.

Hi guys please can you post antutu stability screens

Hi Guys
Basically had two S4's from phones4u, my first was the black mist, which had intermittent faults and in my opinion overheated. This was sent
to Samsung who said that in a nut shell it was fine and the S4's ran warm get over it or words to that affect. As I was unhappy and out of the 28 day return I decided to sell. I was still in love with the S4 so bought another again from phones4u from an ad as an upgrade but I was given the receipt.
This one is the arctic blue version which is really sexy hehe and I love the look, problem is this one seems to also run hot in fact even hotter than the black mist, I was hoping as the blue model was newer Samsung would have identified the heating issues and built the next batches with possibly better thermal compounds or some other way of reducing overheating. This version also occasionally lags and jutters from time to time, I find when on power saving mode they both ran smoother.
My problem is I only have a few days left on the 28 day return so I want to make sure that I havent been that unfortunate to have 2 brand new s4's that are faulty, I know that the s4's run hot and I know that a lot of people are complaining about smoothness, but how hot is the norm and how smooth should they be?? is the question.
I've had loads and loads of phones including, htc one, iphone 5, S3, various windows phones, so I know how smooth smooth should be.
I would like to root and put a custom rom on but I'm holding out to know if this phone is faulty or slightly faulty so to speak, or if everyones S4 is as hot and every so often jerky, I find internet very jerky especially when using chrome browser simple things like scrolling, its not my wifi as my wifes s3 and ipad mini run smooth or smoother.
On Antutu my benchmarks vary from as low as 21000 to as high as 26000?, I know that Samsung is involved in this benchmark rigging thing but surely thats not right?, sometimes I have wifi on dont know if that makes a difference both to benchmarks and heat?.
When I do a stability test, the top half of the screen gets very hot and normally temps start at 30 and rise to around 40 with a gradual increase, as for the stability it goes from 140 to sometimes 70 (3 or 4 times) it also takes around 15% out of my battery for around a 10 min test.
I have attached screens as luck happens the last stability test the phone went to under 40 as you can see, I charged the battery left it a while then ran the test fresh, please can you run the stability test on your s4's guys and put my mind at rest or help me prove to phones4u my phones running hot.
My firmware is UBMGA - i9505
Many thanks

Of course s4 is hot when you use processor a lot or when you recharge s4. Mine hasnt ever become uncomfortable hot but it is warm. Antutu score doesnt mean anything because everybody has different apps running and so on. You had two s4 and it is almost impossible that both of the phones has problems. Remember that s4 is very powerfull and it is very tight package so it is normal if its hot.

My SGS4 is always hot during playing games. Sometimes extremly hot. I've sent it back for warranty repair but they said it's ok. So no luck.

S4 is hot
its hotter than S3 i used to have. It says 1.9Ghz but in games or benches its sometimes lower even than 1.5Ghz because of thermal throttling... when i used 1.5Ghz as max in setcpu i had better results in 3dmark! yep! and antutu score become stable - a bit lower but stable, with 1.9Ghz i had 24000-25600. with 1.5Ghz i had 24300 almost every time.
But now im using UV kernel and i UV -0,50V and i set thermal throttling temp to 90'C, now my antutu score became almost stable at ~26100
I think samsung overclocked this S600 to much... 1.5Ghz is almost stable but 1.9Ghz is definitly not.

[Q] G2 Operating Temperature

Hello guys, well i've read every single post about the phone's working temperature on the forum but i just can't figure if my phone is working fine or not, because mostly everyone on the post refer to the temperature as "warm" "bit hot" etc, which is very subjective. I'm a bit worried because my phone (D806, running stock ROM) gets quite warm after like 20 mins of surfing the web through wifi, or after chatting a bit on whatsapp. By "a bit warm" i mean between 32-34 deg centigrade, refering to battery temperature of course. Now, after reading everything i can't figure out if this is a normal temp for this phone or not. I can also say that the min temperature i could measure (with just cell radio on, in idle state) was 25 degrees. The max temperature i could reach (running antutu for like 4 times one after another) was 45 degrees. Now, i'm confused because someone in a post said the max temperature he got was 34 degress, and his usual temp was 24 degrees. I couldn't even get 24 with the phone completely idle. So, i'd like to know your experience, since i can still exchange my phone for a new one if it's defective. Thanks in advance.

Hi,
There is nothing wrong with your battery temp. You can also check you CPU temp (nope, maybe you will have scared )... Fortunately you didn't saw your CPU temp during your 4 Antutu runs...
The temperature (CPU or battery) depends of your room temperature and your current use. You said yourself with 4 Antutu runs the temperature increase, nothing abnormal even for the battery..., same thing after browsing for 20 minutes even in wifi.
A guy had 24°C battery temp in idle and 34°C max, well, what was the room temperature? Nothing running in background? What he was doing?
I mean even in idle, screen off, your phone can do a lot of things especially if you have a rogue app keeping the CPU busy so there could be a little more heat.
In any case there is a thermal protection (thermal throttling) to prevent damages in case of "overheating" for both CPU and battery the CPU freq decrease according to the temp. Even the screen brightness can be automatically lowered. In last case the phone shutdown if a high temperature is reached (about 100 °C for the CPU). The max battery temp should be about 50°C, I don't remember exactly.
Don't worry, as you reported there is nothing wrong with your tempetatures... Same thing if you take a look at your CPU temp, can be arround 70°C in heavy use, even a bit more in really heavy use.
We have a quadcore device running at 2.26 Ghz, all is enclosed without thermal cooling... it's normal to have "heat" with all the components.
Use your phone and profit, no need to monitoring each minutes your temperatures. You confused yourself by only reading the °C, not how or why it is compared to the other posts you read. Each user have different room temperature, use, settings, etc... you can't have the same temperature as xx user. An average yes, I agree and here you are in the good average...

Viking said it all. Nothing abnormal there, but anything over 30 degrees is elevated temperature and should be avoided

Guys,thanks for your responses. I still don't get something tho because one of you said that my temp is normal (about 32 deg. while browsing), but then you say that anything over 30 deg should be avoided, then i don't quite understand. My phone gets between 30 and 35 deg while regular browsing, it's mostly a bit over 30 all the time i'm actually using it, SO, that's wrong or not? That's the part i don't quite understand.

I guess vPro97 made a typo or he was sarcastic?
Over 30°C for the battery temp is not dangerous at all, about 45°C also. Imagine people living in a really warm country when they use their phones...
Don't worry, already said, there is absolutely nothing abnormal with your temperatures, nothing... all is fine regarding your use...
Don't panic
