How does your phone heats up when running stability test cpu/gpu?
https://play.google.com/store/apps/details?id=com.into.stability
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
CPU OC 1420
charging
7 minutes of cpu/gpu stress test 51°C

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
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.

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.
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...

60 degrees celsius? Wow mine was doing 45 degrees while playing dead trigger 2 and I thaught I had a faulty handset
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

I can't care less. It has 1 year warranty.
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.

it's to my understanding there are 2 sensors in the N5, one for battery and one for cpu

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

i dont think you know what the fail safe temperature is
http://productforums.google.com/forum/#!topic/nexus/cVuWVDW-hyY
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.

Not irrelevant... Mine overheated while attached to my laptop and the led screen blew up. It developed a black bubble at the bottom near the home button.

No phones currently have no active cooling on them
Also heres what happened to my HTC One X
http://forums.androidcentral.com/ht...e-x-battery-draining-rapidly-overheating.html
It drained rapidly and the backside was always hot when it wasn't even in use just sitting on my desk caused it to got hot
and i would charge it to 100% and took it off the charger ~10 mins it dropped to 70% just sitting there idle and the back is super hot
my point is the charging circuit only controls for overcharge with is extremely dangerous

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!

And the size and weight of the phone would grow enormously. Are you kidding? And what phone offered anywhere by anyone does what you suggest?

I'm not the smallest guy on the planet, but can you imagine the size of a the pair of cargo shorts/pants that would be needed to carry a liquid cooled smartphone? Massive!! lol
Fwiw, my N5 routinely gets to 107-111f when doing some intensive things with other background intensive things running as well (i.e. banning trolls on my phone both through Tapatalk and Dolphin while listening to a streaming content on mobile wireless and sitting in the sun soaking up some Vitamin D).
Oh ya!!

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.
HAS ANYONE NOTICED OVERHEATING OF PHONE MOSTLY WHILE CHARGING, GAMING (should expect some heat not this much). I play PUBG on smooth basic plus extreme with no AA and gfx lower settings. Still phone heats up. FAN seems to be a marketing gimmick too. Circulation of air is v poor.
My question is can this be fixed via twrp custom rom tweaks. I'm willing to experiment.
Excuse me. Are you one of those geniuses who charges his phone while gaming?

I think nubia have fake temp status.
Or is that a bug i don't know
When i turn the fan on at max speed. Temp increased. Things like that happen. Or when i come back to auto from performance mode. Tem goes up.
Which is weird. Makes me believe that all this temp and gpu turbo and fan is a gimmick.
Air temp is 26 deg Celsius.

How do you measure the temperature? Was it a temperature of the CPU or the battery?
If your sentiment is not a user error or a fluke, then your unit is defective. Here's what one of the most prolific Youtube reviewers said about the fan - "it was keeping my phone 8 degrees cooler than my Samsung." I assume 8C, not Fahrenheit, because the reviewer is from UK.

YouTube ers are paid. I check the temp stats from gaming app . Inbuilt.
Plus the phone feels hot in hand. Not 8 degrees cooler. And Hunan hand can easily feel 8 degrees change in temp over 5-10 minutes

Instead of admitting that you were sold a defective unit and exchanging it for a working one, you think there's a conspiracy that involves the Nubia corporation and "paid youtubers."
But hey, I'm thinking this guy is not a psychopath. Maybe it's just a user erorr.
Maybe he thinks that having a fan in the phone should make the phone feel cool to touch during gaming.
Maybe he simply doesn't understand that the fan may be lowering the temperature from 55C to 47C, and that 47C will still feel hot to the hand.
Hey guy,
Can you actually provide real world numbers with screenshots?
No one has experienced anything like this before, so either your phone is defective or you have a nervous breakdown.
Yes, the phone overheats while charging but if you switch on the gaming mode to check heat also in certain Celsius comes down gradually and quickly in my case. So fans not a fake gimmick. Also when you are playing games heat is normal for heavy graphic 3d rendering titles like pubg, fortnight I play pubg with extreme HD and it heats but the fan keeps decreasing the heat. My suggestion is to charge where there is air free flow of air like a fan, AC, or cooler to keep ambient temp in control.

Yes
That is understandable, but then what is the fun of a fan gimmick when you need additional external air circulation with AC.
Even with clash of clans. Not much demanding game phone heats up. Plus additional charging while playing the temp increases continuously.
Circulation of heat and cooling inside the phone is poor. I'm starting to wonder if the battery has nay issues of heat while charging.

Low iq behavior? Projection much?
You are the one who's playing games while charging the phone, something that should not be done to a cellphone battery especially with 26C ambient air.
You realize that by charging and playing you are heating up the battery and the cpu at the same time and that's really going to cut battery's life real quick?

Apologies for the mess. Was relyed on Google voice without proof reading. I have edited now.
I'm not suggest to plug in a charger while gaming, it will make the phone hot, especially when you using the original fast charger. Anoher thing is you hae to know you can't get a high performance with the low temperature, if you get a very hot phone, the cpu will running in a low clock speed. The RM3 can get highest score on Antutu so I think the fan is doing something.

I agree the fan is going something. Had the circulation been a bit effective i think it could have been utilised in a more better way.
Anyways i was just charging the phone while gaming to test the heat limits. Not actually doing it.
Still i have noticed battery heat while standby charging
