Phone heating normal?

Good afternoon all,
I have my Optimus 4x for around 3 days now, the phone is great in general but i noticed when using applications that require more power the phone heats considerably in the part where the LG symbol is located in the back and i think even more in the front where the screen is.
In my case happened with Skype video call (around 20 minutes) and other time playing a game (frontline commando) for 10 minutes, after it becomes normal again, but as i said i think in general when using heavy applications.
Should i worry about this? is this normal? someone else experiencing the same?
As the phone is new i would like to know if is a defect to send it back.
i have software version V10d
Thank you

Its completely normal, the Tegra chipset is just behind the LG logo.
Got to remember there is a quad core and 3d graphics package sat under there

How hot does it go anyway? Is it hot enough make you feel very uncomfortable during a call with the phone next to your face?

I have never had it get hot during a call. Only during something like Dead Trigger.
Even then, it's hot but I can still hold the phone. When you consider skin burns at something like 44 deg C, its not really getting that hot. Especially when you think it's a quad core CPU with no heatsink or ventilation.

Yes i imagined exactly that there would be the processor, of curse is not hot enough to burn but is definitively hot.
My only concern is if in the long term this temperature wont damage the screen or other parts of the phone as for example in my laptop the nvidia video card heated so much that got damaged.
do you have any idea How should be the "normal temperature", is there any app to measure it?
For example does the galaxy 3 gets also hot ?
Sorry for so many questions but im not an expert and i want to be sure i make the right decision
To answer the call question,for me just gets hot as i said when using heavy applications, i would consider just annoying in the case i received a call meantime i played (etc) and the phone was hot but not to the point to say im burning.
Thanks for the previous reply's

Tegra 3 will be shutting down when it reaches about 90_degrees afaik. Don't worry your phone won't die. Only the battery... :-\

Anyone with any update? Its been 5days since I am using p880 and it gets heated up as experienced by other users near LG logo my OS is up to date (v10e)..also I feel battery drain much faster with when heated. Anyone can confirm same?

..cause->effect, not the other way around, and so on.
But generally, a passively cooled device like this /should/ get hot on the outside fairly quickly, instead of containing the heat. On the 4x, it seems like there's a frame on the inside going around the edges that will lead heat there first. Away from the battery, the middle of the screen, that sort of thing.. Ideally that heat would then disperse without ever reaching uncomfortable temperatures. Thought they did pretty well with the 4x. Seen several tablets.. with lower heat signature than a tegra 3 chip.. end up with a few typical spots the heat ends up on the outside (middle of the screen, contact points on sim card, battery, memory card frame, stereo jack.. copper, see?), because the heat is really being contained inside the device much longer than it should.
And then people happily use the device until it breaks. I don't think that's really a problem with the 4x.

I also have this heating problem land looking for a solution. I have p880g (Canadian AWS version) with 10c firmware. It got really hot before I even finished 1 game of The Game of Life. it wasn't skin burning hot, but hot enough to be uncomfortable, similar to a laptop power adaptor. I also think that it was hot enough for the phone to start throttling. The quadrant benchmark I ran while it was hot was lower than the usual.
I don't think that this game is too cpu and gpu intensive that it''ll max out all the LG O4X's hardware. I tried this same game on Motorola defy with cm9 (overclocked to 1ghz) and galaxy tab 10.1 (stock). Both ran it perfectly fine with no heating issues.
I hope someone can help. It makes this phone's Tegra 3 a bit useless if it starts to overheat with less than 15 minutes of playing a game. If this normal and what LG intended, then will likely be my las t LG phone.

Hi guys! I have the same problem - hot phone when I'm plaing some games. My question is: How many percent of battery drain the game for 10 minutes? In my case, for example bad piggies 10 minutes = 10% of battery. I have brightness of display on 0%. So I installed app called PowerTutor (it show you how much energy drain every app) and this app said that bad piggies drain about 600 J for ten minutes.
How about you phone? Thx for answer...

No one answer?

That's ok. All cpu's are active in this game's so heating is normal.

Heating Problem Solution
After searching this forum more I''ve found a solution. The heating problems for the LG O4X is fixed with the v10f and up firmware update. This thread has more information about it.
http://forum.xda-developers.com/showthread.php?t=1974616

So I have v10H (newer than v10F)...
And I dont think that bad piggies are used all 4 cores, because my friend have only one core and he plays this game smoothly.
When you play this game, prosecutes to charge your phone?

Same in my case when playing games (swing shot, death dome..etc) it gets heated a lot and battery drains like passing minutes...
I played dead trigger with NO wifi,no 2G/3G, no nfc, no bluetooh and less then 50% brightness in 30mins more then 50% battery drained. And this happened with every game I tried.
I bought this tegra3 device only for games but this heating and battery draining is making it pretty useless for game.
Any developer can throw some light please.

Unfortunately v10f couldnot resolve my issue and I find v10f/v10g is same as my regions latest v10e.

heating is not a problem its normal because its tegra3 and Quad-core 1.5 GHz Cortex-A9

well, I`m on v20a official software. With v10h I had the issue of overheating when playing a flashout 3d free game - I dont know how, but thermal protection didnt work. After 5 minutes of play, I felt big heat, so I came back to home screen and at this moment my beautifull-brand-new 4XHD went black screen - no buttons worked, even keeping long pressed power...so I took out battery and re-inserted. After start the screen was shaking like it had low-refresh rate applied...I was terrified. I took out the battery for one hour and after this all went to normal. Then I updated by official LG app the software to v20a and checked that phone gets very hot with this app again, but this time I managed to close and uninstall app without burning my new phone...so I gave it a 1-star rating and a comment in google play. Now I installed some app to monitor temperature inside and I see that with nfs:most wanted after 15 minutes of game, it was at 40 degrees (celsius). I checked with other apps and I see this was max and it felt/feels very hot, though this wasnt so hot like I felt with flashout 3d.
My question to all of you 4x HD users is:
can you tell me your temeperatures? Min/max ?
I mean: I have minimum 26/27 celsius (phone in the pocket), with data,bluetooth,nfc on I had about 30 celsius, and maximum 40 celsius (when playing demanding game). Also I saw big increase in temperature outdoors with bright sunlight(I have automatic brightness on all teh time) and while having data,bluetooth,nfc and GPS on.

[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...

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 .

Gets a bit warm, not over whelming, about the same as my Nexus 5X

While it gets a touch warm - even when it was downloading and installing all 150 apps, 15GB of Google Play Music, with Folder sync doing data transfers it still stayed much colder than my Z5C ever did with a couple of minutes use. That would probably burn toast!

I thought it got pretty warm, but idk. The material might have just transferred heat to my hand easier because my hand was sweating and you could see it on the back of the phone.

The phone gets REALLY hot when its constantly downloading something.

Anyone got any battery temps? If I run games for an extended period I end up around 43C. Cooler than my Moto X Pure which would hit like 47C.
Idle and light use around 30-33C. The phone has never felt hot to me in any circumstances so far.
"Feels kinda warm" isn't a very good measurement.

If anybody can provide heavy load or gaming temps I'd appreciate it. Also any additional info such as case or no case.

Usually if u charge and use a device at the same time that's when things get hot pixel 2 got warm enough to feel threw a tough spigen case wile browsing and charging nothin crazy

Hmm not great. I came from a note 7 which was very warm to a note 8 which was ever so cool. Considering the pixel but the heat issue among other things is a right turn off.

it will not get as hot as your note 7. note 7s had a few of them explode which just goes to show that sometimes the phone would get hella hot. not a lot of them did so it wasnt a huge problem when referring to how many blew up vs how many were sold but i presume higher than avg temps on all of them

It gets hot sometimes even when you aren't doing anything.

No heat issues so far. The best example for heat is to use Hangouts video calls. Generally with every previous phone I've owned I got a massive battery drain and heat when using FHD video calls. With the Pixel 2 the difference is huge.
We have to consider that this phone is easily ramping the big cores to 2.45Ghz and still maintains a good temp. I'm not suffering temp throttle like I was used after 5 minutes or more of continuous usage/browsing/etc.

It only gets warm when charging. I did not experience any kind of extreme heat coming from the phone and im a heavy user.

Only gets really hot when using AR, not so during games

I havent found anything to overheat the pixel 2 and im a heavy user. BUT that would be a lie. ****ty snapchat can make it warm up sometimes and well, Ark Survival really heats it up and eats right through my battery.

Pixel 2 Hotter after CreamPie update
My Pixel 2 is warmer than usual since the update. Prior to the update, it heated up a couple times mostly due to crappy game apps, which I removed.
Now it gets hot under various circumstances like running Android Auto, which is currently unstable until they release an update to fix whatever they did to break Android Auto.
It also gets warm in my pocket. I'll notice it's warmer, pull it out and cant see any reason that would cause it to warm up so much. This Pie update is crap.
Dont upgrade if you havnt already. At least wait for them to fix the bugs in Pie.

Could you test CPU temp and throttling using this app? It would be really useful.
I usually set it for just 5 minutes and it's enough. Also, tick the boxes in settings to show cpu temp and share a screenshot. Thank you!

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 Razer Phone 2 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!

I just got my brand new Razer phone 2, and for general use like browsing, you-tube , social media it gets hot at the camera area ( CPU sensors says sometimes between 35-45°C , when gaming it goes up 55°C or maybe more ) I know it has a glass back so i don`t know if it is normal or not?

Played PUBG to test the phone. Set Razer Game Boost to 2.8 Ghz and the phone does a fantastic job of simply becoming warm all-over, instead of getting any hotspots.

I only play DC Legends, haven't noticed any hot spots, and general heat is very minor, but of course its not an intense hardware demanding game...
Edit: for other general usage, Youtube streaming, Pandora, etc., haven't noticed anything worth mentioning either, minor heat, no hot spots.

I run a spigen case on mine and even after long sessions the phone never seems to get too hot and I play games like xcom and pubg.
In cortex I always set the games to the max settings

Impossibly hot
I bought a Razer phone 2 last month and it stays cool when just browsing the internet or watching videos, but as soon as I play any games like PUBG or Brawl Stars the phone gets too hot to even hold. I don't know if this is something that I should contact Razer over but it's ridiculous. Not only does it get hot to the point where it is physically uncomfortable to hold, but the touch screen becomes glitchy and I'm practically unable to use it. I was completely baffled by how a phone who's main selling point was gaming and advertised a cooling chamber got hotter than any phone I've ever been through playing the exact same game (Galaxy S5, Galaxy S6, Galaxy S7, Galaxy S9).

Je ne joue que sur DC Legends

heat and obvious first question
I don't honestly put this phone down much throughout the day and I do have a silicone case, yet I don't notice much in the way of overheating unless it's charging. Not advisable to use resource heavy games while charging anyway. But even then it's not excessive.
My question is have you stitched the performance profile in Dev options.
Which then leads me to my noob question, if that profile is altereed does it take precendence over the cpu speed options in the booster app or is that what the app changes if Dev isn't enabled?

They're different options so neither takes preference over the other. The profile in the Dev options controls how early the device will start thermal throttling while the game booster app controls actual CPU clock speed.

Freezing Temps & Vapor Cooling?
I live in Minnesota and it's winter, so temperatures can sometimes drop to -40°.
Extremely cold temps made my HTC One shut itself off and report way less battery charge until the phone warmed back up to above freezing. And my LG Stylo 5 screen will gradually stop responding to touch if it is below freezing temps for too long. My concern is whether extreme cold has an impact on performance, especially considering the vapor cooling technology, what happens to the Razer Phone 2 if that vapor chamber is frozen?

Hi sir i've same issue with you but its the opposite, mine is so ****ing hot because even its rainy season but im live in tropical so temperatures can sometimes up to 40°.
of course my phone so easily raise the heat, cpu can up to 60° hot and battery can be 50°
Im even to scary to touch it when device becomes that hot. now i already buy a cooling fan from memo and it quite helps but find another issue because it uncomfortable to hold if put on to the device. i just wonder is case razer arctech really can make the phone more cooler like some few people?
