[Q]Heat Issues???

Just received my One S yesterday and after about 10 Mins of use it felt a little hot on the backside. And this is without any type case on it, so I then unlocked bootloader and rooted and lowered the CPU Speed but it still feels kinda hot after very little use. Has anybody else felt this........

How hot you are talking about? Did you play any heavy game or something?
You can install some battery app to see what the temperature it goes so people could compare yours with theirs.

The only point at which it got a bit too hot for my comfort was sitting in my lap with GPS and google navigation running for about 20 minutes screen at full brightness. Picked it up and was a tad bit toasty.
Other than that, gaming, video streaming etc no heat issues outside what i consider normal for this type of device.

I had some weird heat issues the first couple of days when I got my phone, then I started using an app killer, didn't help... so I stopped using it, and the heat isn't as bad as it was before. It's due to heavy cpu/gpu usage from hd games or just installed apps that don't have any cache data, or high visual load ones in general.

No Gaming just browsing and normal things like texting and google +.
Dont get me wrong it runs fine with no reboots or freezing, just felt a bit weird when it got hot posting to google+ other than that it runs like a champ

Is this normal on Galaxy S3?

Hello all, new here and have a question
So I have the S3, it's only been 2 weeks, no root.
I've thought about rooting it, however I don't want to yet break the warranty as I think there might be a problem with the phone.
My Quadrant bench is usually around 5500-5700, however when running intense games (nova, the dark Knight rises etc), the phone heats up loads, which I assume is normal, the first 10-20 mins of playing is fine, after it starts to drop to really low fps, force closing the app and running quadrant it gives me a bench of 2500, now the weird part, it stays at the said 2500 for hours, even if I let the phone still and come back later its still 2500. The only way I've found to fix it is a battery pull for 5 min.
This same problem happens when downloading files at a fast speed with a torrent client.
Is this something I should be aware of, or is it normal?
Please help!

I think it might be because of overheating after playing games;s3 underclocks its cpu when it overheats so its not an issue big enough though

I had the same problem. The phone would heat up at the bottom to the point where it's a bit uncomfortable to hold.
This heating was followed by crashing and a few times my home screen would be wiped completely.
I had to get a replacement. So far so good, but it still heats up when browsing on the internet.
Any suggestions? I'm not rooted and I use go launcher. My vibrant never got this hot.

CPU Temperature

I’m looking for the CPU temp in Galaxy S7.
Anybody know what are the values in green and red box in the pic attached signify?
This pic is from AIDA64/CPUZ

The red must be CPU cores, or at least related to that. Have no idea about the green one.

Wherever I see in the forums people only talk about the value in green box and they think that device is relatively cooler even under heavy load. But gotta say man the device heats up worse than my G4 even in minor load when referring to the values in the red box as you said. I wanna know is there something up with my device alone. What does you CPU Temp. reading after about 15 mins of heavy game session like with 'NFS No Limits' in your device in AIDA64? PLease post a screenshot

I don't play games on the phone. I tried a few just to make sure the phone is OK when gaming but in 5 minutes I got bored.
My phone gets hot, 75 Celsius when updating several apps, or right after an OTA.
I think this is normal, as I changed the first phone ( display issue ) and both reached the same temperatures in similar situations.
Edit
Also have a g4, that one gets hot more often than the s7.

Oh! Thanks for the reply. This is the first time using glass/metal phone, maybe that's why I'm very sensitive to this problem. Is that a S7(flat)? Never had seen anything above 60C.

Yes, simple s7, not edge.
One time got very hot in my pocket, for no apparent reason.
But in battery stats I noticed that Google services percentages increased from 6 to 16, in about 20 minutes. This happens also on g4, about once or twice a week. It lasts from 10 minutes to a half hour, or I restart the phone and no more issues for a while.
It's hard to catch the s7 above 70 Celsius, I guess the cooling system does it's job really fast. We need an app to monitor and record temperature changes in the background. The only one I know about is CPU temp, but is not showing real CPU temperatures, it's fake.

Got the same situation (temp around 65-70 degrees) especially when updating apps by play store. Its getting hot on the back near the camera. But when updating is done temperatures are very fast dropping to 30-40 degrees. I think it's normal for this kind of device, made from glass and metal. Would be greatful for more observations from you guys. Cheers.

Yeah, Most app in the place store aren't able to read the actual temperature from the S7. Maximum I've seen with those are 38C in ~20 min session of gaming. As I said haven't seen S7 anywhere near 70C but near 61C in AIDA64 but after ~20 min session of gaming. It does take about 5 mins to completely cool down. Don't know it's normal. Is it!?

As you can see from all the below linked videos, the temperature never crosses 40C in any testing under heavy load. But how can we get 60C, 70C and all. They are even saying device isn't much hot. How is that even posssible?

I have no idea what and how they tested, the fact is that mine got very hot a few times. I only check temps when I feel the phone hot, and that was only when updating some apps, right after the OTA restart.
The temps from a gun are going to be lower than the core sensor reading. Always.
Is this gun any good for external testing ? I almost bought it

Bought it online? Check the reviews.

Didn't bought it, I've seen it in some store and took a photo
It's about 20 euro's.

Seems like a local item. May not give you accurate readings but it's up to you. If you want a good one try Amazon.

Here are something based on my recent tests and findings,
The problem is when the device is under heavy load(NFS No Limits game). therm_zoneX values goes upto 61C, which I don't care if the device is still not much hot to hold in hand but it isn't. Compared to my LG G4 it gets hot soon for the same amount of load based on my tests. And makes me unpleasant of the fact that the I can't enjoy the amazing performance of gaming in this phone not even longer when compared to the HTC & LG phones I had. Even simple tasks like switching between Whatsapp and Tapatalk in the background for almost 5 min made the device unusually warm while there isn't anything else heavy running in the background. All these is considering the fact that my room temperature isn't very hot. What is your opinion?
I think the below attached images(4) will help you understand it better on the temp. variations on various tasks and where do I feel it warm/hot. I strongly believe it's unusual based on my experience in previous 5 years with various devices. Do you observe something similar. Please have a look.
PS: The NFS No Limits temp. readings were similar to someone who posted in the different thread.

Is 34°C on average/light use good?
36-37°C when updating apps and using the phone at the same time

S7 Hot while normal use

I just got my Galaxy S7 4 days ago and i notice that is getting hot when i am using it normally for lot of time like 1 hour strait.. If i use games it's gets warm almost cool so no problem there but in normal use like i start web browsing, looking on youtube, making calls or reading on Google Now it gets hot. I am not talking hot like unable to touch it but almost there. Like, a little bit hotter and i need to stop touching it. And while it does not burn my skin is really uncomfortable to use it like that. So are the S7 you guys have do the same? I come from iPhone and that does not get hot on normal use so i don't know if this is normal or not but since i saw the new S7 cooling system i supposed that should not be happening.

Web browsing can use a lot resource so the phone might get hot. Also cooling system in s7 work by transfer the heat away from chipset to outside that make phone hot to touch but make chipset cooler.

Sd820

It seems that qualcomm didn't fix anything related to overheating.. Samsung should get ride of those.. and find a solution for cdma networks. The exynos variant it's overall better

My SD820 has never made my phone hot to the touch threw my symmetry case though I can't deny the SD810 was a failure. I thoroughly enjoyed my s6e+ with exynos and wouldn't mind having it in my s7e but I don't feel in any way hindered by having the sd over the exynos.

The 820 gets hot. Really hot. I was shocked at the amount of heat produced by this phone.

Unfortunately neither the exynos variant does run cool. It goes preety warm if you're just browsing with chrome... Yes, it depends how heavy the pages are (eg javascript etc).. But in general i find the phone to get pretty warm.
A screenshot (from aida64 thermal section) after about 1h of using the phone, mostly browning, some music, a little youtube, whatsapp, twitter.
@A0425A can you post a screenshot after few minutes of browsing with chrome? Thanks!

I'm also facing a similar heating issue. My phone heats up to 57°C just by opening the camera app and taking a few pics. In fact I turned off Wifi/BT/GPS just to make sure. Is this normal? What is the temperature range

yes Last night i use chrome for the first time,only a few webseits then phone get hot,but never get this happen when i use stock browser.

Well same problem here. Didn't se this thread so i created a new one..
My battery temp goes up to 40c just using Chrome sometimes. Is this really normal ? I have exynos in my phone.

I used debloater pc app to block a ton of useless bloatware on my phone yesterday and my phone is staying cool now. it used to get crazy hot too but now it runs cool. maybe give that a try.

I'm not sure how to export a full list of what I disabled. it was over a 100 packages though. I'll play with it tomorrow to see if I can get the list because typing all that out is gonna take a long time. also, 40c is not that hot. I had my phone get over 90c before many times. sometimes it still gets pretty hot but not nearly as often anymore. like I can have Google apps running with location on for over half hour with my display on in my car and it would be ok, where before it would get pretty damn hot.

Damn! That's pretty hot.. Well, maby there is no fault in or phones. I'll guess 40c is pretty normal when using apps like Chrome.

I got a SD820(Verizon) variant and I have the same problem.
I've done some analysis about the heating, like watching CPU temperature.
What annoys me is that I think it is acceptable when you playing a heavy game, but when you're just configuring or browsing the web it keep warms.
When I lock it or charge, there is no problem at all. Samsung may have f*ck*d up in a software level, because the overheating isn't always related to heavy tasks.
There are times that I'm playing and It keeps cool, so I really think It's not about the hardware itself.
In attach i'm showing it right after unlock screen. I'm in a 24 degrees Celsius ambient.
I hope Samsung solve it in Android Oreo version

My s7 was getting extremely hot while using Maps, switched to here maps and have seen a significant improvement.

It gets warmer - ca. 40C, but didn't noticed any lag caused by it, so no overheating for me.

No overheating, seems the snapdragon 820 has solved the heat problem of the 810. Till now never experienced a temperature higher than 40-43°C. And no lags.

Mine lags specially if I set video to 4k. And also if im doing multi tasking.

My phone only gets little warm near RGBC/laser but thats it. G3 was almost all the time hot/red hot near/under power button. When i tried to snap some test photos and about 3 mins of 1080p video and 5-8min 4K it got warmer but nothing more, after shutting camrea apk down i got a warning that the device is hot and camera wont be avaliable for a while. When charging it gets warm but that is normal. There is no lag or stutter, maybe when you played some graphically advanced games NOVA,RR3, simcity when you power down after unlocking ther is a half second lag before a animation/start screen kicks in and thats all, interface runs preety smoothly

sony xz is so ****. it lags like a mother ****er and over heats. cant send 4 snaps with out it having a fit. Then once it starts i cant record a snap it just jips and zips about. i dont understand y its doing this. its a brand new 500 quid phone.. it shouldnt be doing this 3 months into buying this ****
