Hot cpu

I noticed when browsing the web that the phone quickly gets quite warm so I installed StabilityTest and TempMonitor from Play store and ran a Classic Stability Test, within 2 minutes the temp went to 55°c and after 10 min is was 59°c, anyone else having these high temps? Running on battery...

Ok, thanks, was that battery temp or cpu temp?

Sorry that was battery. After 15 mins, CPU was up to 55c, didn't go any higher.

I have the same issue with my HTC one S, while i'm using browser (internet, google chrome) or download something with network mode "Gsm/WCDMA auto" my phone constantly changes between HSPA and 3G connection and heating up to 45,5 C. At this time, the battery consumes 1% of every minute. This is a problem of firmware of radio module or something else?
Thank you.

is anybody else concerned with how hot it gets? It takes just a few minutes of browsing and playing around with apps to bring the temp from 26-28C idle to 35-40C when the entire backside gets really uncomfortably warm. did somebody have a chance to play with different units to compare if they all do this?

Yeah it gets pretty hot, but I don't think it's too much to be concerned about. I think it's just an effect of making the phone so thin and making the body out of metal that means it heats up pretty quickly. As long as it's not going over 60 degrees I wouldn't worry! And if it does, you probably won't be able to hold your phone anyway

[Q] Serious Nexus 5 overheating problem

Hello. I'm new with the account here, but been reading this forum for years.
I'm creating this thread because my new Nexus 5 (which I have for 20 days now) is overheating more than a normal mobile device should.
When i bought it, it had 4.4.4 Kit kat android, and I had that one for about 5 days, and in that time, I didn't notice any overheating, or maybe didn't pay attention, can't remember really.
But after installing official Lollipop 5.0.1, the device is heating pretty good even when browsing internet for 5 minutes, at about 30-40% brightness.
**** Please tell me if some of your devices are acting the same, and is it worth a try to install back an older android to try if it will stop overheating, or my device may be faulty and should I take it back for another one (or maybe switch to LG G2) ?
Because I'm still unable to post image links, i will write it down:
- Ambient temperature: 23 degrees Celsius
- The temperature sensor is taped on the back side, at the side of camera, this is where it overheats most. (even if not using camera)
- Phone temp after staying on standby with screen off: 28 C (it's not warm but it is warmer than desk which it is sitting on)
- After staying idle on home screen with screen on for 10 minutes (50% brightness): 30.5 C
- After chatting on Messenger for 10 minutes: 34.3 C (feels warm)
- After recording video for 4 minutes: 41 Celsius!!! (almost uncomfortably hot in the whole upper half of the phone, both the back side and the screen)
- After 15 minutes letting it cool down, with screen off of course, it is 38 C (still hot to touch), and it stays like that untill I reboot the phone, then it cools down.
The test took about 50 minutes, and after that, battery was drained for about 25%.
-While charging, the phone does not overheat, just gets a little warm which is OK. (haven't tried wireless charging)
P.S. I don't play games on the phone...
Please act quick in case I should return the phone...

the only time my phone gets hot is when im intensively doing a lot of things..
for example.. im playing ingress, have tether ON, and my two sons are using their tablets connected to my phone playing ingress too..
but if i turn off the game and turn off tether, it cools down..
to me it sounds u have something intesively using your CPU and perhaps GPS and other radios.
hold power button.. when PWR OFF shows, long press it and reboot into SAFE MODE...
use the phone for a bit and see if it gets warm... this should tell you if its apps installed.

I only used wifi, no tethering, no GPS, 3G, NFC or any other radios, cell signal is good so phone is not searching for it.
- In safe mode, it still gets warm when using camera. When browsing internet and watching images in google search, also but just mild warm..
- But after sitting and thinking, I've found a problem! After recording with camera and leaving it to cool down, it didn't cool down because it had to make an effort to upload that 5 min video on Google drive via Auto backup!
After turning the Auto-backup off, it is now much cooler!
I will post tomorrow with the results, if something changes...
Anyway, thank you!

First of all, "warm" doesn't mean anything.
Battery temperature does not mean much either, as the CPU is what generates the most heat.
There is a battery temperature throttle that reduces the CPU frequency, but it is almost entirely pointless as the CPU will always reach it's own throttle temperatures MUCH, MUCH earlier than the battery will. The CPU starts throttling at 65C CPU temp (NOT battery temp), and shuts itself down at about 105C CPU temp. Unless your battery somehow reaches a batterytemp of 70C+ (nearly impossible because the CPU will always hit it's throttle first), then I would never even take it into any sort of consideration unless you have a physical battery defect.
Using the camera generates heat since it's CPU and power intensive.
Using the phone in general will generate heat.
Keep in mind that mobile devices are passively cooled, not actively cooled with a fan/liquid.
Not sure what you're so worried about.

Lower your brightness

Lethargy, thank you for a short physics lesson. I'm already into physics and cooling systems so all is clear. I was just worried a bit because all of my previous phones weren't getting this warm (hot), but also never had a multi-core processor in phone eather, maybe that's the reason why I never experienced this before.
Battery temp (measured with app) gets up to 40-42 degrees Celsius, while the phone case gets up to 41 when recording video. Of course that temp won't damage the device, I'm not worried about the processor, but that temp is degrading battery life, in long term.
And about the brightness, phone is not meant to be used at lowest brightness all the time, so that shouldn't be an excuse for high temps. Just sayin'...

The only thing that sounded odd was how it wasn't cooling down until you rebooted, but it sounds like you figured that out with the automatic upload setting.
41-42c battery temp can be normal after prolonged usage, though personally I usually see that after a short gaming session. My brightness is around 40% and high brightness will cause extra heat.
Otherwise the phone is very thin so you can feel the stacked SoC and RAM heat up through the skin fairly easily, right around the camera area as you mentioned.
I think each device and CPU is slightly different and can vary by a few degrees under load as well.

Your temperatures are fine and you shouldn't worry about it. It's average for a Nexus 5, and there are throttles/shutdown temps anyways, for both the battery and CPU. I've had mine for a year and there hasn't been any sort of issue, normal usage should be negligible to the condition of the battery.

Ok, everything seems to be ok then. Now I can go to sleep without worrying Thanks guys!

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

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

Heat

Some phones are great to take camping because if you play Asphalt 8 long enough, the back warms up to the ideal temperature that can bake bread. Rate this thread to express the extent to which the Samsung Galaxy S8 stays cool under extended heavy use. A higher rating indicates that even when playing strenuous games for long periods of time, the phone doesn't get uncomfortably warm.
Then, drop a comment if you have anything to add!

No only on Galaxy 8 but most of the models get heated while extended use. It is better to keep it from using it prolonged hours. I have not heard any incident of blast but it is good to be safe.
It is not about particular brand but it happens with almost all of the brand. If you use any mobile devices for prolonged hours it will get heated and sometimes may be exploded.

Lol....3 posts and you can came to spot this nonsense?!

Using TomTom app for over an hour yesterday and my S8 really contributed to global warming. No it wasn't charging at the same time and not attached to the windshield nor in direct sun-light.
On the other hand I experienced this same effect with previous smartphones ?

You wouldn't expect to use a PC/Laptop for an hour or more and it not get hot. The same goes for a phone which is essentially a small PC!

max Temp with mine under load is 43°c (Aida64). Battery is a bit lower.
Anyways most if not all of the modern SoCs are getting warmer then odler Models (Which is normal) . I think thats why many Devices have a Heartpipe build in now.
The only SoC where i was worried was the Snapdragon 810 in the HTC M9.

I found this device (G950F just to be more precise) to be a bit cooler than the previous iterations (and I've used all it's predecessors), probably the large footprint has an influence here as well.

Mine gets a little warm, but I haven't gotten it uncomfortably so, regardless of what I've thrown at it so far. Seems to top out in that "noticeably warm but not uncomfortably so" range, which is nice

Had my phone for only 24H no heat yet! but the same happened with my s7 edge for some reason even after re flashing the stock rom with ODIN it started heating like crazy! also I haven't taken it outside yet, my s7 edge's battery goes up to 37 outside! even up to 38!

Had mine for 2 months now. It warms up after prolonged use but what do you expect? It's normal! Nothing unusual

Question Rog 3 Temperature

Hi, I want to buy the Rog 5 but I've heard that it has high temperatures even from light use (like when using YouTube it reaches 40degrees celcius). How are the overall thermals? I'm not talking about throttling I'm talking about general temperature when using the phone for light tasks. Any info would be highly appreciated. Also any info on battery life would be great too

From what I have heard from Youtube and reddit, It is a hot phone because it keeps internals in a good temperature, plus they achieved better temperature after update.

But having a warm phone isn't a good sign is it? I'm currently using a huawei p40 pro plus and it's super cool (probably because of the ceramic body). You mentioned an update, so is the rog 5 cooler after the update? On YouTube Technick ran a battery drain test and the Rog 5's peak temp was almost 60 degrees celcius

Thanks man. This really helped.

I got it a few days back, I can share some impressions. Yes, it's a hot phone. Yes CPU temp gets up to about 40 degrees sometimes when browsing or multitasking. Gaming also gets it to about 45 - 50 on CODM and Dead Cells and between 55 and upwards of 60 with Genshin Impact. A Peltier effect cooler like the FunCooler from black shark brings this down about 10 degrees. This temperature is mostly felt at the center of the display, while the sides on the back, where the batteries are, remain noticeably cooler. Perhaps their goal was to dissipate het through the display, idk.
I haven't been able to notice any drop in performance yet, even with the thermal limit set to low. What I don't know is how this affects the chip long term, but I hope it doesn't degrade for at least about 5 years. Either way I'm sticking with a cooler for Genshin impact just to make sure the device lasts longer.

Thanks for the reply. 40 degrees from just web browsing is ridiculous. Rather dangerously high and will definitely degrade batteries. Think I'll give the rog 5 a miss

40 is the CPU reading I get. Batteries stay about 5 degrees below the CPU for normal use generally according to my observations, just to make that clear. Not sure which battery temp it's actually reading though, since there are 2 batteries.

40 is still too high though for normal usage. I've never heard of a phone go that warm. My huawei sits at 22 maximum.

Phone arrived 2 days ago, in my experience It Is not that hot, while browsing / YouTube / Instagram It Is cool (about 31/32 °c) and my ambient temperature Is around 20 °. I have played 1 hour call of duty and It reached 37 ° on the cpu, while the phone was hotter, especially in the middle. I think this Is how It works, getting hot outside to be colder inside. Also I updated to firmware 2102.81 which helped a lot.
