Overheating

Hi all, i have stock v10b ROM with no ROOT or custom kernel. My mobile is not restarting and its not heating while charging, its heating just when i play for e.g. Dungeon Defenders for 5 minutes. Is it normal ? My phone never restarted yet but i have it jst for 4 days...

No worry, its absolutely fine. Your are not alone. Jonny walker, keep walking.
Even thought the battery caution shows: Do not exceed 40Degree Celsius. Just that you will smell the smell of 'burned' lithium when you open your battery cover.
Wahaha
After my exam, I'm going back to LG with the smell and get a new set perhaps? Hehehe

if you are not joking here i think your battery is faulty

Update to 2.3 can fix it what do you think ?

It depends on what you are talking about.
It is perfectly normal, that electronic compnents produce heat when operating. More work produces more heat. So if you play some graphically intensive games you should expect, that the phone will produce some heat.

Its ok it will heat, but after 5 minutes it is bad, i had overclocked SE X10i played this game for 3 hours and it was cold as ice... :/
That heat come from Camera or near camera my battery always got about 29-36°C

OK, my question is, if i flash undervolt kernel, can it help ? And then , i need to know how to flash back to stock, Is LG updater enough ? Or i need to flash it any special way ? If yes please give me link ^_^

lol 29-36 deg is normal.
my galaxy tab also heats up while charging.
it is normal for phones to heat up when your doing something like browsing and gaming.
and i used to have x10i also. that one has a serious overheating problem. i can't charge it during the day cause it heats up too much, the phone freezes while charging.
i reduced the overheating by using a charger that has less Output voltage;
the one that come with the box has 7+ Voltage output, i am now using a charger that has an output of 5.1V ( i got the 5.1v charger from my optimus one)
i don't know if this can damage your battery but you can also charge on your pc using the usb cable. it charge your phone slow but does not overheat it.

Nah, its true... Thats why i'm sending it back to LG...

I mean while gaming its about 50°C , and can undrvolt kernel solve my problem ? Mby for a little bit..?

I don't think so it help. Under voltage affect the performance(I assume) too. The heat is not because the 'nvdia' it flaunting its power. Its because of the battery...
All i can hope is the 2.3 update... If nothing changes, i'm gonna sell this on ebay for 100usd... starting bid 1$ ==

But that super heat come from area around Camera, there somewhere suppose to be a processor i think... I think im gonna try this kernel, just need to know how to get it back to stock, so i can use warrancy when needed...

50deg? Im surprised it did not melt your phone. Lol! I have been playing lots of gameloft and tegra exclusive games but mine never overheat beyond 38deg. Use your warranty.

my friends 2x got to around 39 degrees when we were just surfing the net in 3g, thought its about 28 degrees outside as well... you think its normal ?
hes gonna play an HD movie and see if the temp is not too bad later on

LOL anything below 45 degress is fine.
46 above can shorten your battery life.
50 above can damage your battery and your system after prolonged use.
and its perfectly normal for phones to heat up while using 3G.
all my previous phones heat up while on 3G browsing.

Ill try to use my warrancy when ill have time, than ill share my experience , bcuz i bought it from Samsung CZ....

I have tried custom kernel, its still the same but my phone is now laggy at all, when i turn on screedn it takes about 5 seconds, and starting apps is really bad too, please help me how to revert it back to stock...

Over night I left my phone on the loading cable... when I woke up this morning I noticed that my phone was extreeeme hot and had a black screen of death..when I booted up I saw that the clock settings were set up to 1,4ghz although I set it to 1ghz the evening before...I just uninstalled pimp my cpu now and have no overheating issues till now. I was really scared and thought that my phone just melted inside ..

if i were you (or any1 else to be honest) i would not even try to overclock this phone for 2 simple reasons:
1) as aremcee has said, the hack used to overclock the tegra 2 is just really dirty, he doesnt approove it, and as he is one hell of a smart guy, i have to agree with him.
2) why the hell would you need to overclock it if its already lightning fast. only for benchmark whores imo. i mean this is no optimus one which has a 600 mhz cpu. that one you would like to OC, to see some improovements lol, but not this thing.

I agree, my phone is still fast and i underclocked it on 900MHz but, starting apps , and starting screens takes about 5 seconds, and its pretty much so i all time think about its Dead or Its going to restart, ill try custom rom with underclock. BUT noone said me HOW THE HELL I CAN REVERT BACK TO STOCK KERNEL ? I ask this about 4th time...

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.

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.

Nexus 4 throttle

http://www.youtube.com/watch?feature=player_embedded&v=koLJ4BU9tgc
Swedroids test
It throttles at 36 C and shuts down at 59 to 60 C.
They should increase the throttle to 45 C and when 45 C is reached make the throttle more aggressive would be a better solution.
What do you guys think?

If it gets to hot people get the yellowing... I would rather run cooler and not worry about it.
Is this throttling effecting real world usage or just benchmarks? Not being sarcastic, asking a question.

Well i dont know, i dont care about benchmarks, just thought about informing what i found.
And increasing the throttle level and making it more aggressive later on was just my opinion.

I would like to see a comparison with the iPhone 5 and Galaxy S III on what temperatures they shut down.

I think that the video was pretty painful to watch! lol WHO on earth would run a phone to death like that?? Hope they have an extended warranty... For real though, I would like to see them bump up the throttling temp a lil but in the real world most users will NEVER experience something like that because that app is meant to run your phone into the ground! I hate that they even make benchmarking apps cause it makes me competitive but I have found that the N4 is FAST as hell so I don't need anything else to prove that to me... Good vid though for the info but lets all step back into reality...

I'm thinking the S4Pro is rated to a higher temperature, and the thermal shutdown is really more for battery health than processor health... Regardless, 11 minutes at 100% load with no real cooling system...

Does the Galaxy S3 also shut down at the same temperature?

12 minutes with the CPU pegged at 100% on all cores with no cooling is impressive, IMHO. Yes it clocked down to 1150MHz but that's plenty fine.
No real world task will come close to pushing the processor that far. I doubt even gaming will task the cores so much that the phone throttles them back.
A lot of modern laptops won't run 12 minutes of solid prime95 before clocking down. This c2d 2.8GHz laptop I'm typing on now will clock down to 800MHz after 15-20 minutes of prime95...but it doesn't throttle at all when doing real world stuff, even compiling or encoding etc.

In my opinion the throttle should engage at 43-45c because at 36c its idle temperatures when the phone i just on stand by.

Ok I fear that's a real problem. What if I want to play a graphic intensive game for a few hours? Expecially on a hot summer day?

So much for Qualcomm's butter test

In the video description you can find:
"The reason as to why we published this video is because we've never experienced temperatures reaching ~60 degrees C before, nor have we ever experienced a phone shutting itself down after just 12 minutes of continuous full load, nor have we ever experienced such aggressive thermal throttling. It pretty much throttles down instantaneously from 1.5GHz to 1.2 or 1.1GHz during heavy load.
All temperature readings are presented in Celcius.
The Nexus 4 seems to have some issues with heat development. At least if we are to believe our findings. There might of course be a possibility that our unit is faulty. We are however not alone according to the Google Android issue tracker: https://play.google.com/store/apps/details?id=com.into.stability&feature=.... A google search on the matter will also render lots of user reports concerning heat issues.
In comparison the quad core Galaxy S3 (3G) battery sensor reports ~41 degrees after 13 minutes of full load with the screen set to 100% brightness. It does however lower the CPU frequency to 800MHz at times, but mostly run at 1.4GHz. Our IR meter reports about ~34 degrees if we go ahead and measure the hottest spot on the back of the phone (area around the camera lens)."
For me, this is a no-go. I wouldn't buy a phone that shuts down after a few minutes of processor stress testing. Can somebody tell if the same happens with his N4?

Thing is that if you search the web for this problem, you get a lot of hits about people have thermal issues. I hope it just is a defective unit but it seems it is not the case. The S4 pro seems to be generating to much heat and requires too much power. That's why it empty's the 2100 mha battery a bit faster compared to other devices.
Maybe the S4 pro is more suitable for tablets and not phones.

Very few applications will use 4 cores. Hell, most don't even use 2 cores by default. So the chances of you maxing out all 4 cores in routine usage isn't very likely. The extra cores typically benefit smartphones when one process is utilizing a core already, a different process just gets thrown over to a different core so it doesn't have to wait for CPU cycles. Most smartphone use is "burst-y" so this helps end-users out quite a bit.

99.9 % its not the S4 Pro`s fault, just the lame battery from LG. I mean WTF after 15 secs it clocks down !!!!

Yeah, thats weird. But I could live with it, expecially when the phone runs buttersmooth. But if the phone shuts down after a few minutes of processor intensive tasks that's a big problem. I know that barely any app is using 4 cores simultanously, but what happens if you stress-test only one core? Does the phone also shut down?

This doesnt seem that bad, you're stressing it pretty hard which wont ever be done in real word conditions, for example take intel burn test, most people find this stresses the chip to temperatures 15C+ over any possible real word tests/usage.
You say the SGS3 throttles to 800Mhz at some points well thats pretty poor is it not? Clock for clock the s4 pro is superior and so clocking in over 300Mhz faster when throttled its pretty good id say. If you're comparing the S4 vs the S4 pro (US SGS3) then its pretty hard to say the battery sucks when its got more power! Of course it will run hotter haha.
I think they could put back the throttling limits a bit though, I think it maybe a battery issue more than anything though so maybe its a fault... Please test it by stressing a high end game for an hour or so tracking the temps and clock speed, that would be a much better indication.
edit: Seen your reply before me, It wont shut down like that in the real world! If you stress test only one core I can assure you that it will run MUCH cooler, you are essentially testing 2x the amount in the s4 Pro than you are in the dual core varient, in these stress tests it works pretty much 110% each core, in the realworld there will be idle times and switching between cores handling different threads, lots of variences that should mean it would be ALOT cooler all the time even if using all 4.

1 core likely won't generate as much heat, and not to mention the whole point of the cores is to distribute load and operate at max efficiency rather than less cores at max.
I understand that some people have issue with the throttling, but until people report that they can't play x and y after z minutes it is a non issue. It may have to do with the glass, maybe LG battery. It is possible the throttle is there to preserve the higher recharge cycles LG Chem batteries have.
Unless it actually ruins an app experience, on stock rom and kernel, it is not an issue. If someone would rather pay 400 more to boost their bench by 5% that's up to them.

Mhmm, I guess it won't be a problem in real world usage. Nevertheless it's quite weird that the phone heats up that much AND THEN SHUTS DOWN, expecially in comparison to other phones like the SGS3, where this problem doesn't occur.
But yes, I didn't hear any complaints about critical-heat-shutdowns in real world usage, so maybe I'm just overreacting. But at the moment it's winter in USA and Europe, so let's see how the phone performs in summer heat
My old HTC Desire often overheats and shuts down on hot summer days when I'm using GPS or playing games, so I just hope my next phone won't have this problem

Mine has been shutting down due to overheating at least once a day. I've just exchanged it so will see how that is.
Worryingly, I will often be doing nothing other than web browsing or similar which should not stress the CPU

Nexus 4 Temperture's

I work in a cell phone shop ( Technician Manager ) so i fix phones everyday. Most of the people on xda and the internet have noticed the nexus 4 getting warm, I myself thought so too. I did stress test's on Three devices 1.) Nexus 4, which was mine Rooted no stock rom. 2. Galaxy nexus, GT-I9250 rooted stock rom. 3.) Samsung Galaxy III, T999. Rooted running Cm 10.1 latest nightly. Out of the three I found that the nexus 4 had the lowest temperature overall.
. The Samsung Galaxy Nexus got 50-58 C, basic web browsing and watching a short clip on YouTube. 60-68 C Gaming. Game used Eternal Warriors
The Samsung Galaxy S III got almost the same temperatures as the Galaxy Nexus 45-50 C with basic web browsing and watching a short clip on YouTube. Gaming 50-60 C. Game used Eternal Warriors
The nexus 4 with basic web browsing got 35-48 C. Gaming it got 50-62 C
All of the Three Devices ran for 45 minutes and used the same Game/ video to watch.
Just Wanted to share this information, hit the thanks if I've helped you out in anyway

My Nexus 4 gets so toasty if im running Spotify & GPS nav at the same time on long road trips. (And its charging at the same time.)
Kinda surprised to see your results.
IMHO the glass on the back may feel more warm that the plastic back of most other phones because glass conducts heat better than plastic. That is possibly why this phone has the overheating perception in most peoples minds.

That's what came to my conclusion, for the glass that's on the nexus 4. Notice that I don't have it on the charge it's just on the battery. I think you will get higher temperatures when it's charging

The glass is good in a way or another. This way, it helps the phone's internal components cool down by conducting the produced heat outside.

So, when the temperature outside is hot the device get's cooler ? Is that what your implying ?

Yes. The glass absorbs, theoretically, some of the heat inside, and helps keeping the device cool.

Hi,
I agree... I had the 3 phones.
Maybe a thread that can help user about temperature or "pseudo" overheating...
When I see a thread like "My Nexus 4 is overheating, help me" it annoys me. No CPU / battery temperature indicating to see, just a "it feels hot, it overheats" or "I see some threads about Nexus 4 overheating, mine is also overheating, I read it " (it's real ).
Plus people confuse CPU / battery temperature...
Or people complain about "overheating" when playing a game or browsing while charging their phone...
Even 70°C for the CPU temperature is (almost for the the stressed people) nothing and there is a thermal protection in any case. Thermal throttling that reduces the CPU freq according to the CPU temp, same thing for the battery. And in case of extreme temperature -> shutdown.
I remember the max CPU temp for the Galaxy Nexus: 120°C before shutdown , it's not the same CPU but it can give an idea... The max for mine was about 90°C with some benchs, I see some people (simms22 if I remember right ) with something like about 110°C...
With my Nexus 4 (about 21°C room temperature):
Iddle temperature: 24 / 26°C for the CPU and 21°C for the battery
Light use after 15 / 20 mins (XDA app in 3g, homescreen setting): about 38 / 42°C (about 45°C with only XDA app) for the CPU and about 26 / 28 °C for the battery.
Hard use (browsing in 3g, Youtube, camera): about 55°C for the CPU and 31 / 32 °C for the battery (for this I don't remember exactly).
Extreme use (multiple benchs): about 72°C as far as I see for the CPU and about 38 / 40°C for the battery (maybe 42,**°C once).
Browsing while charging the battery is about 44°C and the CPU about 60°C +.
With _motley kernel, no undervolt, 486 Mhz / 1.51 Ghz, and CPU temp set to 70°C before thermal throttling.
I do agree that some people can have an overheating problem but not all the users / phones like we can read in different threads... and people that claims their phones overheats... when tey post the temperatures all is normal...
The feeling of warmth and real heat are two different things and it's very subjective to say "my phone is very hot".

Hi Viking37,
I feel fortable after reading your post.
I have been using Nexus 4 for a month on 4.2.2. and feel very bad on the heating and warm. (compared with previous Desire HD temperature)
I am based on Bateria App, showing only the Battery Temperature.
On Light use after 15 / 20 mins (Chrome or Dolphin browser on 3G): about 30 to 42°C on Battery, but i do not have CPU readings.
On Hard use after 30-45 mins (Youtube, Waze on 3G): about 30 to 42°C on Battery, but i do not have CPU readings.
I noticed i do not gets battery temp reading more than 42°C....
Hope you can advise what app you use to check the Battery and CPU temperature.
Thanks.

Hi ykit88,
You're welcome
For the CPU temperature I use System Tuner pro (on the Play Store and there is a free version), you can add a widget or download for free an "extension" to add the CPU temperature reading in the notification bar (you can set different update time).
There is also at least one more app (I mean that it works perfectly but I don't remember the name).
Your battery temp seems normal to me, it depends also of the room temperature and if you have a case (even if it does not have much influence).

@OP I don't know maybe is just because of Easter but I can't understand your first post, - is just too many Galaxies and I don't think there's Galaxy Nexus 4? But I may be as well wrong.
On the other hand phone getting hot is not an issue for me as HTC Desire used to get a lot hotter just with some browsing where you could smell a little bit of plastic

this. im sooo tired of telling people that their cpu temp is normal. it bugs me to see people posting that their phone is overheating at 45C, lol. someone even claimed that their 36C phone is overheating, when body temp is 37C

Very good explanation don't forgot the desire has only a single core. While the nexus 4 has 4 cores . It's only natural that it would get warm

i can barely feel the warmth of my phone at 34°C and i never even reached 40° due to uv

The really only reason why everyone has this idea of overheating is because the glass. It was mentioned a thousand times because glass conducts heat :

Has anyone felt the phone get hotter with a case on rather than it being naked?

Well, if you think a bit about it, it makes a lot of sense.

Depends on what case your using.

Wow,how did you managed to go to 66 C on the gs3. I,even with the charger plugged in and playing heavy games(MC4,NFSMW) i couldn't make it even to 45 C

He said t999 your on the 9300 different phones. The s3 T999 does heat up pretty quick but compared to my g2x that really did overheat occasionally thee's run cold

Nexus 6 Heating

Okay, so just received my nexus 6 yesterday. it seems to get pretty warm while charging and playing simple games like crossy roads for around 10, the battery temperature goes to 42-4 degrees celcius. and while charging it also goes to around 41-42.
could this be due to the fact that this is a new phone and the phone is taking time to do its starting operations. will this problem eventully go away. i also updated to android 5.1
Hope i get a solve for this.
The app i use to monitor this is CPU Temp(also includes battery temp).

If using the quick charger, the phone will get hot. Especially when playing a game and charging

On the Turbo charger the first two step of the whole charge cycle are at a higher power 14.4W each the last is only 8W. More power more heat dissipation-especially if your using data and your processor is working hard, then it can get really hot. Toward the end if the change cycle it is considerably cooler-especially is your not doing anything in the phone.
Edit: I forgot in use the CPU can ramp up and get hot/warm(depending on how heavy the use(some "simple" games may have more running in background perhaps-like ads and such) but is pretty normal) but even more so if your on WiFi or data too.

Any phone gets hot while playing games and charging at the same time... The nexus 6 is actually pretty good with its heat compared to other Nexus phones.

Bro i wasnt charging and playing at the same time. When charging i keep the phone aside. Then it gets hot. Even while playing 10 mims of candy crush it gets upto 42 degrees celcius of the battery.

I had heat issues at first. I'm assuming all the app restoring I was doing was the culprit. I did decrypt my phone the very next day and it runs pretty cool
