I would first like to say that I understand that there are other thread out there on the subject of overheating. However most of the threads involve users with rooted phones and most of those threads are a year or two outdated.
I Have a Nexus 4 16Gb that was purchased 9-10 months ago Manufacturer refurbished ( Not bought through google however ) for my father who has used the phone for a majority of that time. Just recently it was given down to me as an upgrade ( I had a horrible phone prior ). As my father was not using the phone for anything intensive at all or using it for more than 5 minutes at a time the overheating issue didn't affect him much. Shortly after I started using the phone, the overheating issue really became a nuisance. I decided to run some benchmarks on the phone and track how hot it gets.

The first picture shows a peak cpu temp of 86 Degrees C, after running Antutu5.7.1
Second pic shows a peak cpu temp of 97 Degrees C!!!, after running antutu a 2nd time
Third pic shows a peak cpu temp of 91 Degrees C, after playing Fifa 15 for 10mins. BTW: I was solely in the transfer market during that time, not even playing a game which would really put the cpu to work
All of this data comes from indoors with the AC on
The phone idles in the low to mid 40s, light internet browsing will get it to 54-57 degrees ( However use it for more than 10mins and it will hit 62-63 very quick ), and youtube at 63-65 after 3 mins
The phone is not rooted and is running a flashed image of 4.4.4 directly from google, However it was having issues before the phone was upgraded past jelly bean.
I cant imagine this is normal, is it?
What can I do to get it to run cooler?
How much will undervolting/underclocking help? (and how much will it hurt performance)
Is it time to Just upgrade once again?
Also can anyone point me in the right direction to a thread that will help me fix the problem hardware wise as I am replacing the battery because it cant hold a charge, maybe I should go a little deeper and give it some thermal help.
Thank you Very Very much for any help
PS: If the pictures aren't showing up for you, Im sorry. This is my first post, they are not working for me either. However my description of the tests and temps should be good enough.
Is the phone in a case?

Normally, however for the both the antutu benchmarks it was out of its poetic atmosphere case. It was in its case for the FIFA test.
Nexus 4 overheating
I had a similar situation, but it would only reach 93C if I use Faux Clock to disable the battery temp sensor, so it doesn't throttle and run antutu with CPU Burn, but during normal utilization or even heavy utilization, it never exceeds 73C. The issue is that the CPU never touches the phone chassis properly. To fix that issue permanently, I opened up the phone, removed the board and noticed that on the phone chasis were the board leans on the CPU side, it has an empty space like something missing. I fitted a small copper shim which is 1.5x1.5x0.5, I used thermal paste on both sides, on the SOC contact side and on the chassis contact side, then put the phone back and the temps dropped by 10-20C. The phone gets hotter across the surface instead of a single hot spot, but also delays the throttling mechanism by a good 5 minutes ( I disabled it anyways) and also noticed that the GPU wouldn't clock down anymore. I got those copper shims on ebay.

Thank you I will certainly look into that. I called Google this morning and then was transfered to LG. I read somewhere that I may have luck getting a replacement outside of warranty, but the end result of that call was essentially "sucks to be you". If anyone else has anything else to add, please do. And if I could get pointed to a YouTube video or written instructions for getting to the CPU and setting a copper shim that would also be a huge help.
Thank you again

There are some tutorials around the web for that, just google Nexus 4 copper shim mod, they would even tell you which copper shim to get. Just get a standard copper shim with 1.5x1.5x0.5 dimensions, and a good thermal paste like the Shin Etsu or GELID Solutions GC-Extreme, don't use conductive thermal paste like Artic Silver, it is outdated and takes time to cure.

230c sometimes the BGA ICs fall off and I have to open the phone and reball the ICs and flow them back into place
I got my first SGS2 and it was really getting hot especially when streaming movies or playing games etc..i could not touch the back portion where the camera lense was. That phone had a 3g connectivity issue..so i had to return it..anyway while waiting for my usb jig to arrive..i bought another SGS2... using it the same way like my first phone, it never got hot till now..even playing games or streaming movies..it only gets warm and when i checked the battery temp..always showing about 36 to 38 degrees. On first phone, my record temp was 49 degrees and maybe it could have gone higher if i did not shut the phone down and cool it..

Got it to 45C tops, when playing heavy games continuously.
It goes upto 45 for me as well. I felt it very hot just once on the second day after I got it where I feel it went above 45. After that I've been using a cover so I dont notice the heat much and since that its never gone aove 40. Its better if you install some temperature app to monitor. Battery circle is good as it gives the temperature as well as the battery percentage remaining.
The reason it heats up so much is because there is very little gap between the components and the phones body since its very thin so the heat gets transferred directly. But it cools down pretty easily.
Sometimes it could also be because of an app- in my case it was twitter. I login only with Wi-Fi and I have disable data so it kept trying to connect and that heated up the phone. After that experience, I always turn it off after I disconnect from Wi-Fi.
My phone get's VERY hot, will also crash and a yet to be unmentioned thing, is that if I turn it off an hour or so it feels the need to automatically turn itself on again. Anyhow I will be getting a replacement of the phone selling it as brand new and be getting a new different phone.

My phone used to get hot initially when i used to use stock kernels... Then I flashed insecure kernels...one thing I noticed that when I flashed Chainfire's kernel, the phone tries to stay at an optimum cpu frequency even while playing games on it...I tested this using cpu spy... I found the phone rarely used 1200 Mhz frequency but still felt buttery smooth... when the phone constantly stays at 1200 Mhz, then cpu heats up, but when it is at 800 Mhz, it never heated up even with the heaviest usage... and ya, my phone is not under/overclocked
mine doesn't get tooo hot unless i've overclocked it or something, have a go at undervolting it, look at tekrak's overclock guide in android development for advice on that
it should help temperature problems, i hardly get them
I've done the air condition trick after it got too hot twice. But I had a doubt as to whether the sudden heating and cooling will have a damage on the phone and so stopped that. Now I just wait for it to cool down.
I've got it up to 55°, playing order & chaos over wi-fi, max brightness and connected to my charger supply.
Connecting it to the charger itself heats it up a lot so I can imagine what will happen over wifi with heavy gaming

Didn't it damage your phone?
Got this phone just yesterday. Highest temps i've had so far while gaming over WiFi and charging: +39C CPU, +42C battery. Before launching any game i take the phone out of protective case and set CPU to 200-800MHz.
The only problem so far is Pocket Legends that freezes every few minutes. I found the thread about it here on XDA and on official website. This game was the main reason why i bought this phone. Wanted to play it on high-quality, large screen... Sigh

Hei, i let my phone charghing a night and in morning when i put my hand in the phone, was verry hot .. unusualy hot ... i accessed an aplication that tells me the battry temperature .. and the temperature was 50 degrees ... . I oppened the back lid and behind the sim card i saw a melt .. The plastic has melted ... what could cause that? The phone is working but the battery said evry time is empty ... when i put to charge it sais charging but in that time sais and battery empty .
Battery burnt out. send it back for warranty.
it`s only the battery? the phone has a little melt .. i will try to get a picture ... should i send and the phone to waranty or only the battery?

RMA the whole shebang, a molten phone is unacceptable.
There must be something wrong.
I've tried using graphic intense games and benchmark programs, and charge my battery often, just to try to get it hot.
It gets warm, so you can feel it, but never more than that.
I run Lite'ning rom 4.2 with Black theme, Android 2.3.4 and KG3 .
so is possible that the warranty not accept my phone?

Did you overclock?
I'm stock and have lots of apps installed and never had a problem with overheating. I downloaded a news app and ten minutes later my phone got hotter than it's ever been before. I removed the app and it's been fine since. Certain apps appear either not to play well with GB or Exynos and have the potential to overheat the phone.
I've never really seen any app or HD game that puts MORE heat than angry birds, infact for a dualcore it runs insanely cool.. I've tried upping the GPU from 267Mhz to 400Mhz and I still dont feel anything that runs warmer.

I'm curious as to what app that was..
First of all duel core is soppose to be cooler the single cores and also use less power then single core so the hole point to the duel core thing is more speed and less battery power and less temp.
If ur melt was caused after u rooted it or/and u used a custom rom u need to put back a stock rom or ur warrenty will be invalid.
oh my word! Defective battery?
It could be a defective battery, which led to an overloaded pin (which got very hot) in the phone. I would return both phone with battery and charger, to get all checked.
The heat required to melt the plastic (about 150-200 degrees celcius) is able to melt any solderings on the mainboards inside the phone, so it should be checked. But probably no harm done, as the backside sits above the mainboard, and the mainboard is attached to the frontframe (screen side) of the phone. I would request a checkup, and a new backplate, if it was me - which is a small repair, in less than 10 minutes...

Not really heat wise, but I can tell you that Grand Prix Story drains battery like a gold digger who just met Bill Gates. Playing the game continuously gives me 2, yes 2 hours of battery life! 100% to 5% in 2 hours!
Which is sad because Kairosoft is one of my favourite game developers.
In true, what goes up must come down - my phone went up ... and came back down - with a thud!
I attached my GS2 to an RC quadcopter using an array of balsa and hard wood, cable ties and foam and took to the skies. Since this is my phone, I have to rebuild a camera mount each time I fly and yesterday and today, I've had 4-5 flights with jello-wobble vibration video - and over beautiful fields too .. anyway, this was my third camera mount of the day and it worked! It did work... before it fell...
the RC quad it as attached to had the camera mount broken (I can make another), two broken props, and some nylon standoffs - on and a carbon fibre rod and LOTS of cable ties!
Sadly, an animal was harmed in the making of this video... a slug (or snail), jad a 1kg+ weight fall out of the sky directly upon it. I'm sorry - at least it was quick!
Oh, and the phone? Fine! Not a scratch or noticable fault - auto focus still works You can see the whole flight ...
I've not had much luck embedding on here so just in case ..

The phone and quad WILL fly again but right now I'm off to sleep - it's been an interesting day!

It landed on grass and soil, doubtless that would have cushioned the impact. If it was solid concrete it will probably do worse.
My heart almost stopped watching it fall,and fall,and fall...Ouch.Madman.
When it hit the floor I farted.
got a big ding on the side after it fell to concrete blocks, i think i should be more careful now
Heli Cow.
Nice video.
Thanks for the great comments everyone.
Almost 24 hours later and I can find no fault with the phone. It was in a silicone case (one that wraps around the phone completely), encased in packing foam and then secured to a light wood mount. Unless the phone took a direct hit on something sharp, the only thing that would affect it is the inertia of the falling and sudden stop. Although I think when it was upside down, it was accelerating downwards!
The quad has breaking points such as the "feet" i made and just tied on. Mainly through ease but they've proved invaluable! Many ties reduce the impact and "break the fall" hopefully saving the quad and phone!
From yesterday, as far as I can tell, there's no damage to the phone. The only damage this phone has incurred was when I used an inferior case which didn't protect the top on my first or second flight and the quad arm vibrated a notch in the front .. GUTTED!
I don't have a reliable way of tracking the altitude yet but I think it was higher than 30m - though I could be wrong. Maybe 100m? Any suggesions and theories to the estimated height? Ideally, I'd like a GPS logger which was capable of running in the background and 1s intervals... Even just height
Looking forward for more vids.

It's hard to jugde the hight from the video. The recordings can trick you somethimes. But it's definetly more than 30m, maybe up to 100.
I regulary fly rc-sailplanes(5m wing span) and somethimes over 1000m (measured with a unit called Piccolario that transmits the height via VHF
You can't trust GPS hight readings.
You have to buy the new S3 that has a barometer
The autofocus after the fall was extremely comical. Excellent videos.

5m wingspan?! Wow! You need to duct tape your phone to one and fly (that's how I first started filming with my GS2... duct taped underneath pointing down)

_________________
On a positive note, the quad is rebuilt and seems to be flyable (only tested slighty in my house). After a test flight and new camera mount, I'll be out making my phone fly again. All going well, there'll be more videos to come...
This time I will turn off WiFi, phone connectivity and make sure it's in FLIGHT MODE. I take it this was why Android has this feature?! I mean what else could it be for?
Speaking of the phone, it has been performing fine (although, I'm not sure my HSPDA/3G connectivity is faulty because of phone antenna jolt or provider problems (TalkMobile). Still testing. It connects, just sometimes doesn't.
Thanks once again for all the great comments and the views - they are appreciated
I want post a little tutorial for do it by yourself. Due to I don't have LG G3 working -obviously- I took the photos with old smartphone: Motorola Defy+, but you could see perfectly. Sorry my bad english, I try the best
Remove all screws in the back and keep safe. When you do it, you see the motherboard, something like that

Remove all connectors: camera, microphone -top- and others connectors you can see
Keep calm, be patient and with something with little tip pry the motherboard. Now, separate from plastic cover. Be carefully.
Locate the top of the motherboard and flip it.
You will see your Snapdragon 801 core in the middle. I don't take photo about, before apply thermal paste, so sorry.
Like you see in the photo, apply thermal paste.
Be patient applying thermal paste, an excesive thermal paste can be worst. Obviously, you can use a thermal pad, but I use what I have XD
After these steps, you only need assembly again the LG G3. Put all screws in their holes.
Then, put battery and try to turn on phone
Like you are seing, the LG G3 goes perfectly.
Now, we're going to test CPU temp and other temps. I use AIDA64, Kernel Adiutor, CPU-Z and other. Now I use Aida64 for Android -obviously-
To prevent, try to test camera, microphone, speaker etc. if it is poorly connected.
Thanks and sorry again for my bad english.
Cooming soon I'm going to use a heatsink case for avoid hight temperatures, but I'm waiting for its arrival. I buyed this heatsink for laptops: HERE I bought this in e-bay, so It is not expensive
Spanish tutorial here: HERE
This tutorial is longer than this, but in spanish. If you don't know spanish, try using google translator or other translator. Thaks.
Obviously, If you broke your phone due to disassemble is my fault and I will pay for a new LG G3, nope, sorry, for a new LG G4. It's my fault and I will pay you a new smartphone for solve this issue XD :silly: :silly:
Great tutorial. I was thinking of doing the exact same thing to my Note 10.1 2014 edition. Parts of it use to get way to hot. But, I found out the heat was caused by the battery somehow. Sounds a bit odd. But after recalibrating the battery in the OS, it stopped getting hot. And it stopped turning off after a certain point. It works like new. But, I am still going to do the thermal past and heatsink thing any way. A cooler processor and other components means a more efficient and longer running device.

i have done this and it works great but if u apply only thermal paste it wont be much effective so u should apply thermal gel and a thermal pad of 0.5 mm thickness.then ur lg g3 will fly.it wont heat even with intensive heavy use.i recommend using thermal gel and thermal pad.
Do not do that.. It is mentioned that thermal paste and thermal pads especially have metal components that interfere with the signal reception . Thats why lg uses a special one. Also you will see that your monitor will be hotter and your back will be cooler. Stay as you were is my personal opinion.
i have not faced any signal issue so dont know about that problem.ofcourse the screen will get hot as thermal pad and paste is transferring the heat towards the metal frame.and display is also located there.have been using it for 4-5 mnths.no probs so far but great perofrmance and low temps.
i recommend this method for heavy gamers only as for normal usage g3 wont get so hot.
and i also recommend to buy a thermal pad and paste carefully cause many could cause probs.
i use mx 4 thermal paste and pad.its the best and even if it does you know flow down to other parts of the board it wont cause any reaction.
you can read about mx4 paste in there website.
Awesome idea but my g3 only gets hot when charging so in not gonna try this [emoji14]
Someone should try this on phone with the earlier versions of the 810 with thermal issues like a LG gflex 2 and see what happens [emoji14]

Interference would happen only if you put the thermal paste or any pad with metallic substance unit over the antenna that is in use. other than that if the thermal paste is on only the components that are getting hot chances are it will not be directly over or even near the antenna components.

Is it your battery that gets hot when you charge? Or is it your phone's components that get hot when you charge? If it is your battery that is getting hot while you charge then you need to get a new battery that one is most likely on its way out. Or there is a possible bad connection between the charging circuit and the battery itself spirit

Just got my G3 tonight.
Will try this mod soon!
Sorry for long time. Now I don't have LG G3 I returned to Amazon due to alone reboots with no reasons. After a little battle with the technical service, they said that guarantee doesn't cover my alone reboots WTF? I fought with them, and after various claims, they said that I had wet the phone " Obviously it's for doesn't pay me another LG G3, I think...I don't know real reason, but I saw a day before how motherboard was, and it wasn't wet.
This mod goes well, but you be need carefully to do. Only do if you suffer overheat problems or you're a heavy gamer with the LG G3. I use a heatsink, I do not do it for nothing, I do it because I was waiting for my heatsink, only do it if you have a heatsink, only thermal paste don't do much more, but you can see a little improvement -without heatsink-.
If you have any question, be free to ask me, and I answer you as soon as possible...If I remember, I can or if OVNIS doesn't kidnap me ha ha ha.
There is another thread regarding cooling paste here if there are anymore questions
Hello Z5 users!
It's my first thread ever posted by me so please forgive my lack of knowledge in creating new threads.
Warning! If you decide to do that mod yourself, proceed with extreme caution, I'm not responsible for breaking your device as it's very easy to break something.
I decided to crack open my good old Xperia Z5 and do something to increase performance and improve heat dissipation.
Firstly, I spent some time in watching teardown videos to have a look at the cooling system. It features metal backplate behind an lcd and two copper heat pipes that are soldered to the metal plate. I took some pictures of cooling system:

There is metal shielding above the cpu and couple other elements. Between the metal shield and copper pipes, there is an inefficient thermal filler, so I removed it.
Next, we've got the motherboard. The metal shield is held by metal clips, so you need a little bit of leverage to lift this up. Between the shield and cpu is a thermal pad (it's extremely thin) which I think is inefficient as well, so I also removed it. Instead of this thermal pad, I just used a little bit of thermal paste which I needed to spread on the cpu (it must be a thin layer). After closing it up, I had to use something to close the gap between metal shielding and copper heatpipes. Firstly, I used 0.5mm Thermal pad with better conductivity, but it was too inefficient. Eventually I sanded a little bit the shielding, it had that uneven surface as you can see on this pictures.
I do not recommend using "metal based" thermal pastes, they're usually conduting electricity and that is undesirable.
I didn't do any pictures inside of this metal shielding, because i added there some thermal paste before and if I opened that it'd very messy.
The uneven surface is the problem, the heatpipes are around 0.5mm higher than the metal plate that are soldered to. I decided to put copper pad. I didn't know the exact thickness back then, so I bought a 1.0mm one and it was too thick so I sanded it down so it'd fit, I found that it should be around 0.2-0.3mm - If you put too thick copper pad and screw the motherboard, it'll push on the backplate and on the back of the lcd too hard and the dark points will appear (I was cautious so i unscrewed it and sanded the pad, so my lcd is fine).
You can even sand a little bit the copper pipes, so the surface will be more even and flat, it'll improve the heat transfer a little bit. I've spread the same thermal paste on both sides and just put everything back together.
The heat is going from the processor to shielding, through the copper pad and finally to the copper heatpipes. It is better from the factory solution, because the heat is transferred almost only to heatpipes and the lcd will be a little bit cooler to the touch, because it's not touching the metal backplate behind the lcd directly.
Do not add that much thermal compound. Please, don't point to me, that I'm using too much thermal paste, I'm aware of that.
Also, I know that the heat transfer surface under the copper pad is terrible, but it's better than stock solution. I've tried using those "soft" thermal pads next to heatpipes to increase the surface, but in the end I discovered that the results aren't that better and the lcd was heating up much more.
And the results are in the attachments. I didn't do a before and after, I've based the improvement on the average points in benchmarks. So check your scores in those, and let me know your stock points, so I'll know better if the mod was worth it. The screenshots are from Geekbench, it's on google play
My antutu benchmark score =112612
Other users average score = 97159
Thanks man . Very nice work.

Awesome mod. Can you please do throttle test using CPU Throttling Test ?
If you want to compare I did it here https://forum.xda-developers.com/t/...geos-17-1-sumire-stable.4049463/post-87250667

Sorry, I sold my Z5 three years ago. This cpu was known for overheating, throttling and actually burning itself to death (Nexus 6P and some other phones with sd 810)

I feel you. Do you recommend going through with modding like you did, or just get rid of this phone ?
I'd recommend getting a phone with a midrange cpu, something like snapdragon 730, 765g etc. These are energy efficient yet very fast and they don't heat up the phone that much. It's much better that way. And also get a phone with like 6gb of ram at least. I bought Galaxy A70 used a year ago, got it pretty cheap and I love it.
Cool work.
