Phone temperature

How does your phone heats up when running stability test cpu/gpu?

It would be nice to post your results here so i could compare them. Im suspecting that there is something wrong with mine from when it was returned from warranty repair.
That ****tards broke network reception when repairing power button, then led flash and gps. (Britex s.r.o., Kladno, Czech republic)
So here are mine

I think you dont know what you're talking about. You mean battery temp?
Obviously they didn't break your phone, what the hell are they gonna do to make your battery heat up, stab it with scissors? Short out cells?

Hey Mungulz,
I have trouble understanding you... sometimes you are very helpful, other times it seems you just want to bully people.
Maybe some anger management classes?
It doesn't seem that obvious to me that they didn't "break" the phone... damaged tracks (increased resistance) can lead to more heat due to a little something called Joule effect, I believe.
Also, afaik, our phone uses its case as a cooler. I don't know if it is supposed to have some thermal paste somewhere for thermal connectivity to the frame, but, if it is, openning it up for repair and forgetting to check/reapply paste can also lead to overheating.
So... for me it's not that obvious. Can you elaborate on why you think it's obvious?

I know what im talking about but that shows only battery temperature. just for reference. If its overheating its logical that battery temperature will be also higher because of heat cannot be diverted to the cooler parts of the phone.
I have disassebled the phone and the pcbs were badly alligned not to mention loosy heatsinks.
Sorry for my bad english.

Is it obvious for you now Mungulz that the repair shop might very well break a phone?
xtrustkillx, your english is great I don't understand what you are apologizing for!

@Lars: Or there are 2 persons using Mungulz' account.
@trustkill: be careful with those stability apps mate. I guess you already know that they increase the wear and tear on your CPU and GPU by subjecting it to threshold load right?
About the temperature, it's a difficult one to compare. I have my battery temperature at 1 to 2 degrees above room temperature when idle. (Therefore 33C from a 31C room.) But it goes as high as 42C if I charge it and not point a fan or AC to the phone. Thing is, I notice that my phone rarely goes above 41. I believe that our boards have an initial level of fail-safe where it lowers down the clock speed when the phone reaches 40C.

I just struggle to see how a poorly installed heatsink (assuming LG messed it up) can attribute to higher battery temperatures. in my mind this would increase CPU temperatures dramatically to the point of thermal shutdown, while the heatsink is not absobing as much heat as it should.
In theory the battery would be cooler if the heatsink wasn't functioning, as the CPU would shut down. I think this is just a case of far too much load on the phone. Really though if you put 7 watts into a phone this size it's going to get hot regardless of how good the heatsink is.
Furthermore, benchmarking while AC charging is always going to produce high battery temperatures, no matter if your phone was built on a Friday or Wednesday.
To me this thread just seemed like an opportunity to rant about LG or the repair centre, with no real goal.

@salisbury: I've seen in vadonka's thread (if I'm not mistaken) that you're right. It's actually something controlled by the kernel. There are three "charging modes". If the phone is cool, 1A (providing you're not in USB mode), after a certain temperature it switches to USB mode (that's 0.5A, either you're charging from an USB port or nor) and after a certain critical temperature it shuts off charging completely. These temperatures can be tweaked at kernel level.
@Mungulz: It seems you switched into your polite mode now. Much more pleasant and informative, thanks. I do not know how the phone is built, but, depending on how far the CPU is from the battery, are you saying it is impossible that having very high CPU temperatures will affect the battery's temp? I mean... in my head this is how I'm thinking... the phone uses its case as a heat sink (and there could be some very small heat sinks inside it), if these are not properly assembled, anything that is in contact with the CPU/GPU/whatever heat source will get hotter with it.
I can agree with you, if you really insist, that it is improbable that a battery in a poorly assembled phone will have temperature problems... but I don't think it's obvious! Even if it was there's no need to talk down on someone that suggested it as a possibility.

Well the heatsinks job is to divert temperatures away from the CPU.
If the heatsink wasn't installed properly, then the CPU would get extremely hot while the heatsink isn't getting as hot as it should be. Which would make the battery cooler than it normally would be. Just the phone would shut down within minutes

[Q] 38 to 42 degree temp is normal for z1 ?

Hello friends...I just bought my Xperia z1 yesterday. I have updated it to 2.257 , with normal usage of 10-15 mins continuously the temp rises to around 33-35 and when i use Camera for around 5-10 mins even, temp rise to around 40 degree and with a game like subway surfers the temp rises to 42-43 degree ... 43 was the highest i saw so far...
Is this ok with this phone ? Or should i go to service center ?
I am using the premium cover i got with the phone, with that on I don't really feel the hotness in my hands but just want to be sure that this is normal heat up with this phone and my phone is not bad..
Also, when the phone is at 43 degree, should i stop using it and allow it to cool ? or should i keep playing the games , use the camera and all...
Any application that can help reduce the heating ? and any better camera app u can suggest ?
Also, please don't suggest to root..I do not want to void the warranty but after 1 year I will definitely root the phone and use custom roms then...

what's the ambient temperature, its its under say 18 then yes i would be worried about that temp, if you ambient is say 25 then maybe not as much of an issue, check the back is the back cover (secured by tape) separating?
If its hot to the touch I would RMA that device

Ambient temp is around 25 only...the back cover just realized is separating from the top end camera side only.
I heard from some friend that If i go to the customer service regarding this heat , they will only say that it is normal as there is no warning message being popped in the phone about overheating.
And at sonymobile.com every one is saying that this is a normal heat up in z1 and on high gaming this temp will even rise to 50+ and there is still no issue except that the battery will drain faster on such temperature. I don't really understand why such heat up is being considered as normal in this phone...I mean it is heating , i can feel it..there can be some h/w issue arise in future coz of this

The explication for the high temperatures, i think, is because the phone is sealed (water proof and all) and the heat can't be very well dispersed in this case. That's why, on Z, many users complained that their phones overheated so much that the adhesive would loosen up (from the back cover) compromising the sealing proof of the device.

This is not always true. Most phones usually do not use any kind of air cooling. There are no fans or even any channels for air to move through in any phone im familiar with. Some phones (GS4 i think?) now have a water loop to transfer heat to the case more effectively, but they pretty much all just use the case to cool down.
When i first got my Z1 i had charged it to full then began using it right away while it was still warm from charging. After about an hour of running every benchmark i could find i started to use the camera on its max setting for maybe 20min before it said something like "temperature is too high, closing camera" (i didnt check the temp but i was a bit warm lol..). I was plugged in for all this usage so i was putting out near maximum heat.
I wouldn't actually be worried about the phone temp, i think this is just the reality of having this beast of a quad core with the standard (very little) heat dissipation. That said i know the CPU/GPU can handle 60-70C no problem, but i would prefer to keep the battery temp below 50C if possible.. Edit: actually the battery health indicator was reading "overheat" and i was at 39C° according to battery temp. I was playing an online game for about 35min.
It would be cool to have a battery discharge widget to show you how much more power is used when all cores and GPU are running, i think some people would be surprised.
The phone should stay cooler if its not plugged in during usage, i think. Also, i'I've never gotten the phone that hot since and im not trying to keep it cool at all.

I use Current Widget it works fine and has a log to file function:
https://play.google.com/store/apps/details?id=com.manor.currentwidget
The phone easily draws over 2 Amps during 3DMark, I guess maximum peak current will be around 3 Amps for some scenarios.That is a lot! Current Widget detected a battery voltage if 4,11V which means a power output of around 8 to 10W peak.
This is on the border of what can be passively cooled in this form factor. Actually it's a marvel of engineering to squeeze so much computing power into a smartphone. And you are right, there is no active air cooling in phones, I have never heard of water Cooling in a handset either, do you have a source? Sounds interesting but I can't believe it
I totally agree on the rest if your post though! Don't worry about heat, the device was meant to get hot, this big 3000mAh battery is there for a reason too. I don't know why so many people get crazy over this, Sony does usually know what they are doing and if they think a high temperature limit is fine, it is.
By the way: In the Nexus 5/ Z1 comparison thread the reviewer stated that the N5 got hotter than his Z1. All modern Smartphones do get hot, it is the tradeoff needed for high performance.

Wow 3 amps i wasn't expecting, but that discharge rate would be required to kill it in an hour. Still nuts, they have defiantly pushed the limits of passive cooling here which disappointed me a bit because this will effect the maximum overclock. I don't know what i need the OC for yet, but thankfully i can just drop this phone in some ice water and it should do over 3Ghz no? My mytough4G went from 1Ghz to 2Ghz so we can expect a 100% overclock here too right? (I don't think the battery could even draw power fast enough..)
And water cooled phones amirite? I was really excited at the water cooled phones, but its not a big deal yet. That NEC probably barely runs cooler, and our Z1 would destroy that cooling setup anyways.. Its almost like they need to increase the size of the new devices to dissipate more heat. Although I'm still a fan of microscopic black hole cooling. Yep, a small singularity should do just fine.
So for now, its ice water and a PS3/BT controller lol.

I really liked the black hole part
Yes just filling the heatpipes with water is no real water cooling, but it's nice to see some innovation. I'd rather like to see vapour chamber heatpipes like on modern graphics cards though, but without any heat sink that would useless too.
You are also right with your more size for better cooling theory, it's no wonder that Snapdragon 800 SoCs are just used in 5" and above devices. That's why I am so impressed with the Xperia Z1f (aka Z1 mini). If I am correctly informed it uses the same SoC as the big Z1 in a 4,3" chassis. That's an amazing feat and the first time a mini variant will be as fast as the big one (unlike S4 mini and One mini). But it will get throttled a lot more than our big Z1s I guess.
Edit: When going for some serious overclocks I would advise you to turn down display brightness completely, that should give you some 0,3 to 0,5 Amps of extra current

I understand your POV but as long as it is affecting my phone, it's integrity and one of the main features for which i bought it with a premium price and a safety measure has to kick in in order to stay everything "ok" like "temperature is too high, closing camera", I'm not so sure about giving it a pass so easily.

However if you leave your device in the sun (car dash or w.e) it can get much hotter then it would from normal operation and when you try to wake the device it will usually immediately power down saying "high temp" or something. This is often the only way you would see this message imo. Pretty much all androids do this, so it really isn't specific to the Z1. An apple device would do the same thing etc.

Absolutely, no arguing.
But I don't agree when this happens while I'm playing a game, while (maybe) other apps are running in the background (multitasking), while wifi or 3g on, with more than 50% brightness level (not to mention maybe plugged to a power supply also to keep the battery from draining). In this particular case, on my old HTC One X, the overheating issue caused 2 burns on my phone's display (but that's another story) and i have them ever since.

So have you actually experienced any shut downs or warnings because of heat? Or do you just want to make sure that there's no problem?
I have been playing a lot if games and used the camera, so far everything seems stable, I have had no problems yet.

Mine reached 60 yesterday while playing dead trigger 2 but the CPU still scaled up to 2.15 so I guess the phone can take up to 65/70 degrees but my hands can't...

PSA: Dont ruin your batterys!

Lithium Ion Batterys DO NOT like to be charged at HIGH Temperatures
​After doing a heavy intensive CPU App, or playing a game and the back of the phone is getting really hot, let your phone cool off before charging
I played Plants VS zombies for an hour and the battery temps gradually rose to around 68C which is 154.4F
Let it cool before charging, use a battery temp app such as "Battery" to monitor temps
I learned the hard way on my HTC One X after letting it overheat and then charging it while it was overheating it reduced the capacity of the battery ALOT and got the Red light while flashing when charging witch means the battery has overheated
Also
Your Phone does not have any active cooling system for the CPU, it has Passive cooling witch uses the environment's temperature to bring down the temperature of the internal cpu
Your PC has Active Cooling (Heatsink + Fan)
The nexus 5 has passive cooling (Heatsink only)

same goes with just casual wireless charging. be careful
A battery dwelling above 30°C (86°F) is considered elevated temperature

Odd, Is it really monitoring the battery temps? it seems to be linked to the CPU temp and the warm part is located on where the CPU is at and not the battery.

Explain my dead HTC One X battery? Exactly not everything works as it should be.
http://www.ti.com/lit/ml/slyp087/slyp087.pdf
if the temp gets high enough the chip cannot react fast enough
or if the charge falls too low lets say 2 volts it cannot charge again because it isn't a safe charging voltage

I think he was actually saying that the charging circuit wouldn't allow the battery to charge at high temperatures. I cannot verify that but since the charging circuit prevents over draw and over charge by cutting "power" it makes sense

It will cut off after reaching extremes. You don't want it reaching those extremes ever though or it WILL take it's toll on the battery.
Battery's don't like heat. They don't like extreme cold either.

Don't think the battery will ever get to 110F as the phone will shut down/not charge at that temperature until it goes down. Therefore, you probably couldn't spoil the battery if you tried with this fail safe implemented.
With someone's personal testimony about a fried phone, I can offer my testimony that I used a wireless charger on my Nexus 4 + played games until hot + charged whenever I wanted to and the phone, which my GF uses now, isn't any worse for wear.

Especially because the Nexus 5 has a Li-Po (lithium-polymer) and not a lithium-Ion battery

Hi
These batteries don't like heat full stop, they are like perishable foods and degrade quicker the warmer they are, regardless of being charged or not. This is why laptop batteries do not do well when the laptop is used mostly on the mains, nothing to do with constant top up charging, it is because the battery is constantly held in the warmth of the running laptop all day and age much quicker.
Lithium batteries do not work well in extreme cold, but this isn't permanent and they return to normal when back to room temperature, and lithium batteries are held refrigerated for storage, just like a perishable food.
Regardless of being used or not, the battery will lose a considerable amount of its capacity just by ageing over a year or two. Given the various safety controls built in, it is fairly difficult to cause much more damage than time alone will cause, so you might as well just use and abuse the battery anyway, especially as most people will be replacing the phone after a couple of years.
Regards
Phil

there's a thread with someone's n5 getting to 45C(113F) while playing games and without shutting down, and he lives in Canada. imagine what temp it would be at in any reasonably warm climate
110F is not safe if you want to preserve the longevity of your battery. period.

Just another example of Google cutting costs to put out this cheapo piece of %$))$!
But actually I did manage to really cook my phone! I set it (plugged in!) in a south-facing window to shoot time-lapse and oh-so-cleverly the sun bright winter sun was streaming through the thermal glass, and on to the silky black phone and...physics happened! About 15 minutes in my insta-greenhouse and I heard a strange whimpering 'ding!' from the phone -- when next I looked it had shut itself down. On reboot Dashclock was reporting "Overheat" "Not charging", and temp of 60+ degrees (can't remember the exact number but it might have been as high as 68!) Panic & a few minutes in the freezer brought it back to normal.
Take from that what you will:
1. It really dislikes being treated like a tomato seedling.
2. Idiot user didn't understand the 'greenhouse effect"
3. The phone does stop charging and goes into shutdown when things get too hot.
Before you judge too harshly, I want to point out the most obvious factor; a truly earth-shatteringly great phone would have come packed with the necessary technology to protect the phone in such cases -- maybe that would be a fan, or maybe it would be better served with a liquid cooling system, but whatever it should have, clearly Google cut corners yet again!

It ain't about the pants, it's about Google being too damn cheap to deliver truer-than-true state-of-the-state-of-the-art! Come to think of it, if Google had the balls to fill those pants we'd have the phone we really deserve!
68 Celsius is about 154 Fahrenheit. But as I said, because it was actually being cooked at the 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 LG Nexus 5X 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!

Phone heats up more than you would think since it's the 808 CPU. It's not super hot, but after like five minutes of hard use, it gets warm. Then it slows down as the CPU underclocks.

Remains cooler than the N5 in all scenarios and heat is dissipated more evenly through the device.
The lower internal and skin temperatures come at the expensive of decreased performance due to thermal throttling.

I notice mine gets a little hot under normal non game playing use, seen it get to 100F.

The top does get warm at times, but mostly extremely cool to the touch

Never had an issue with heat with a few months of use. Only time I've noticed it is when I'm running backup or restore in TWRP.

Compared to my S4 this is an ice cube. Maybe because I have the Ice Blue? The sim card holder in the S4 was starting to separate from the motherboard because of the heat!
It's gotten slightly warm a couple times sitting on the bed or a similar not well ventilated area but hard use and gaming doesn't make it boil. I've never been concerned about the temperature of this phone.

Occasionally gets hot in the pocket for no apparent reason

Phone does heat during multitasking 1 hour Skype call and heavy application of online betting and 1 more application but it does cool down automatically. Still love this phone

sorry

Gets heated while playing games, near Camera!!

My phone really gets hot after some ROM installation and few Boots up whithout resting. Around half top front and rear gets so hot that I can´t even make a call and I have to let it cool to keep using it as I´m afraid it would explode :S. Also performance has an impact when it gets hot obviously. LG, make some work with the cooling because this isn´t good.

My current phone heats up while using mobile data, quite hot actually, how does this phone do?

Mine gets hot when using Wi-Fi tethering and charging.

The website notebookcheck tests for thermals and had this to say about the 5x:
With idle temperatures of just over 25 °C, the Nexus 5X hardly heats up noticeably in idle mode. The handset is also unexpectedly cool under load despite the relatively strong SoC. The hottest spot measured reaches just 37.4 °C here - other premium smartphones often surpass 40 °C. The review sample can even shine with the lowest rates compared with its rivals.

Considering human skin temperature is around 38 degrees C, the 5x remains much cooler than most other devices. It still heats up, but it will be a few degrees cooler than other devices in all scenarios.

I've found the phone fine under every condition other than gaming.
The phone seems to suffer from not being able to dissipate heat very well with it being plastic. I've seen CPU temps get up to 47 degrees Celsius and seemed to throttle and affect gaming performance.

I think the reason is playing an elaborate game.I believe the native android by Google is no problem at all.

I read many reviews and Anandtech analysis of the problem, I was still shocked by how bad it is.
Just install two apps and scroll a bit in Spotify and the big cluster is throttled, holy hell this Snapdragon generation is a complete clusterf**k!
Snapdragon 801 is a lot better.

iam coming from a s801 phone (oneplus one).
it produced the same amount of heat during heavy usage.
i was not surprised after i had setup the 5x first time
s810 is way worse, s808 is actually ok.

Always stays cool exept when you are recording 4K or Slow-mo video.
and even when it turns off big clusters it still feels snappy to me .

Mi 9 T Pro with overheating

By setting up the pubg with maximum graphics the device is warming up to almost 70 degrees celsius, it gets very hot on top of the rear cameras, even more on the right side of the headphone jack in the case and on the screen glass if you touch the lips on the screen glass realize that it is very hot.
Miui 11.0.1

Device is not heating up to 70°C, CPU does. Device is heating to temperature just a little bit higher than battery temperature which is on your screenshot 42°C. Those temperatures are normal when you put powerful chipset like sd855 on high stress for longer period of time.

Just over 1 minute the device reaches this temperature leaving the screen very hot, I have Mi 9 and is no more than 60 Celsius, this device is not normal.

Return it to seller.

Can anyone with the device take a test?

CPU does touch 65+ in HDR+60fps for me but as long as battery temps are <44 everything is good!
Do remember to take off any case/cover while gaming & not playing while charging too.

The point is that the CPU is over 70C °, the rear camera, housing and screen next to the headset are very hot, I feel it in my hand and fingers, it bothers you a lot, high temperatures can burn the screen.
My Mi 9 is no more than 60C °.

I told you that heating so fast is not normal. You have faulty device and return it to seller. You can use google or youtube and you'll see that no one get that temperatures so fast like you do. Here is example: https://youtu.be/C9jSZ4JR0qo?t=1

First of all he is measuring wrong with inexpensive and inaccurate equipment that is not even for checking the temperature of a human being. There is a right place to measure the temperature and not the way it is doing, I did the correct tests and this device has a low quality screen and a poorly positioned graphite heatsink.

I just choose that youtube video randomly, you can ignore it if you don't trust it but you have 1000 other Mi 9T Pro/K20 Pro reviews and youtube videos where you can see that this devise doesn't overheat fast like you say. You wrote: "Just over 1 minute the device reaches this temperature leaving the screen very hot" and I'm telling you that this is not normal and that your device is faulty and for the third time I'm writing you to return it to seller. This is the end of this stupid discussion for me and I won't comment on it anymore. You could use google in the first place to see how this device reacts under stress and you could see that this device doesn't have the best cooling but it also doesn't have the worst. Bye.

guys ... if you can`t keep it civil then you better stop here if you don`t want to have one more problem apart from the one with your device

Hello. I bought this device and is too hot in idle or social networks Use.... Not on gaming (saint seiya awakening) or full charge situations. I think I should change the unit.
In this moment, the cpu is 42°C. And I am not using nothing. Just posting this vía Chrome.

No overheating for me

I don't know how hot it is in your countries, but at idle, my phone is always on 39°C/40°C (ambient temperature at 27°C-32°C), when I'm playing CoD mobile at max settings it barely reaches 50°C. I think it's fine considering that it's an intensive game.

Same issue with my device
Using k20 pro for last 5 months and now when I connect it to charger cpu temperature is going upto 65 to 70 deg. The battery temp is 37 to 45 . Only this happens when charger connected. Using original charger and cables and Xiaomi powerbank. Tried with changing cables and charger still same issue .

K20 pro getting heated while using camera
I have a major problem which i have never ever faced in any other device .
While using CAMERA , my device gets heated in 10-15 minutes and due to this increased temperature of device its very hard to use it.
A pop up message shows - " your device is over heated " and the camera gets closed automatically.
