[GUIDE]Homemade heatsink[GPS FIXED](Really easy to make) - LG Optimus 4X HD

So I was using my friend's Iphone 5 today.I did some heavy gaming and his phone was transfering heat to all areas of the phone equally, making the chipset get rid of heat easily.If you played some games with 4x hd you'll notice only a part of it gets hot, the part below LG logo at back cover.
So I thought 'why not' and tried to transfer heat equally around the back cover.Had a simple but 'can be effective' idea.Surprisingly this worked greatly and I could feel the heat even at the sides of the phone.
So here is what I did:

}
The image pretty much describes it.I used aluminum foil to direct the heat from hot areas to cooler areas.While it sounds too easy it works like magic.
Note that I cut off the connection between the top and bottom aluminum foil so that chipset wouldn't heat the battery up.
(işlemci sıcaklığı = CPU temp and pil sıcaklığı = battery temp.)
No matter what I've done I couldn't get the cpu temperature to go above 60 until I did an antutu stability test and it was around 65 C in the end of the testing and quickly descended to 50 in a matter of seconds.
This screenshot was taken when I had a download of 4~ gb size and phone was just plugged off from charger (all this heats up the battery) so expect battery temperature lower than 40 C in normal usage. (37 ish in my case)
FAQ
Any side effects?
GPS
Did my own tests and while it does not block the signal completly, it weakens them...
With this new method there are no side effects, gps works as perfectly as it would normally and any "possible" (no one reported it so far) cell signal problems are solved aswell.
GPS signal without foil : http://puu.sh/dvF9z/102fc62ba1.png
GPS signal with foil : http://puu.sh/dvF9c/aff68118e3.png
I have toggled gps on/off in both tests before begining the test.
Note that satellites are never stable in my city (signal quality changes per 5 - 10 seconds in both cases due this) so the foil doesn't actually boost your gps signal, screenshots are to show that they both give the same signal quality.
Won't this make my sdcard/battery/SIM card unswapable?
You can still swap battery easily if you ease off with tapes.You'll still be able to swap your battery, microSD and sim card exactly the same way you do now, ONLY if you clothe just the back cover and not the phone as this new method requires sim and microSD slots to be covered tightly.Guide to back cover is under 4th step
But what do I gain from it?
1_)It will increase your battery life.How much depends on how you use your phone.If you put heavy load on it regularly this'll help a lot.If you don't use it long enough to even heat the chipset up it's help won't be noticeable.But even browsing the web gets this phone hot so...
2_)You'll get better performance from your phone : Hot CPU gives less performance compared to a well cooled CPU.Mainly due to throttling*.
*This may or may not prevent throttling on stock ROM as LG has stupidly put a tablet chipset into a phone with only throttling as a temperature adjuster.But I can guarantee no throttling on custom kernels with no overclock.
3_)You will be able to play games without your battery getting drain ridiculously fast.This is mainly due to battery heating up as chipset drains power from it/chipset's heat affecting battery and this will reduce this effect by reducing heat of both.
4_)Extends your phone's life.It is known that running electrical components under high temperature reduces it's lifespans.Battery in particular gets damaged over time, reducing it's capacity and eventually dying off.
5_)You can overclock your phone further as maximum temperature your chipset gets to is reduced enough to overclock it by a bit.
6_)Your chipset will barely heat up to the point of hurting your hands.
How to do it?
You need: 1_) A scissors 2_) An adhesive tape and 3_) A piece of aliminium foil a little longer than your phone (about 3-4 cms longer)
If you adjusted the size by comparing it with screen, you might want to cut the edges of aliminium foil by a bit since back side of the phone has a smaller area than the screen. (do this at step 2)
1_) Shut down your phone (incase battery falls off)
2_) Cut the foil you have to two pieces, one will cover the battery and the other one will cover the chipset AND you'll connect those two aluminum pieces together later on so make the bottom (battery) piece bigger than it should be.
Now you might think this would heat the battery up but our battery has environmental protection and it actually gets hot via the heat transfared through the circuits from chipset to battery.
3_) Make sure you make gaps in the foil for ;
a_)Camera & LED : See how I covered all around them with foil? I just added 2 pieces to cover the top right edges.Don't trouble yourself trying to make gaps for them on the whole foil, use shortcuts.
b_)NFC
c_) GPS ANTENNA : See how in the picture there is a red highlighted spot, half covered with foil and the other half naked? This makes your GPS work.Also the naked part next to it lets your GPS work, so do this part exactly the same as in the picture, if you didn't then don't complain your GPS is not working.Keep the top piece of the square as naked as you can, otherwise the foil may block the signal (in the picture I cut it off like a triangle)
Note : The foil must cover that square even if by a bit since chipset is right below it.Having the foil not touching it would mean this would make a very little difference in temperatures, making your effort go to waste.
d_)WIFI & Bluetooth : This antenna is located to the left of the camera.So avoid foiling the top & left sides of camera.THESE SPOTS ARE FOILED IN THE PICTURE BUT YOU MUST NOT FOIL THEM.
d_)Speaker : Below the battery there is your phone's speaker.Don't cover it with foil (reason is obvious)
4_) Use tapes to stick the foils to the phone.The blue colored marks on the picture are the spots where I used tape on.
Enjoy!
And If you want to still be able to swap your microSD and sim card, do these steps on back cover of your phone (inside of it).This might prove difficult and probably less effective.But if you want even better cooling you can do both.Make sure the foil on your chipset and the foil inside of your back cover are identical and don't block the GPS signal ( http://puu.sh/dzJZ6/d234d3b347.PNG see how I left the bottom left naked? It's because of gps antenna)
And say good bye to your frying pan!

FAQ
Any side effects?
GPS
Did my own tests and while it does not block the signal completly, it weakens them and my phone failed to get a lock without or with foils.
Doing some research, it completly blocks off only if it's wrapped up in foil in multiple layers but test it for yourself.
From my testings it doesn't effect wifi or cell signal so if you don't use GPS (most apps use wifi or data to determine your location) it shouldn't be a problem for you.
Won't this make my sdcard/battery/SIM card unswapable?
You'll still be able to swap your battery, microSD and sim card exactly the same way you do now, if you follow only the optional steps.
Or you can follow the main and optional steps both and ease off with tapes on back side of the phone but optional steps only should be more practical if you swap them daily.
From my experience following both main and optional steps gives the best results.My battery's temperature is around 3 - 4 C lower now (37ish to 33ish) and CPU is sitting around 42 C during charging with wifi on.
But what do I gain from it?
1_)It will increase your battery life.How much depends on how you use your phone.If you put heavy load on it regularly this'll help a lot.If you don't use it long enough to even heat the chipset up it's help won't be noticeable.But even browsing the web gets this phone hot so...

5_)You can overclock your phone further as maximum temperature your chipset gets to is reduced enough to overclock it by a bit.
6_)Your chipset will barely heat up to the point of hurting your hands.
How to do it?
You need: 1_) A scissors 2_) An adhesive tape and 3_) A piece of aliminium foil equal to the size of your phone. (you need an additional piece equal to half the size of your phone if you are to follow optional steps [clothing insides of the back cover with aluminum enhances reduction of tempreature greatly])
If you adjusted the size by comparing it with screen, you might want to cut the edges of aliminium foil by a bit since back side of the phone has a smaller area than the screen. (do this at step 2)
1_) Shut down your phone (incase battery falls off)
2_) Take the back cover off, put the foil on top of your phone's back to compare sizes
3_) Now cut the aliminium foil to 2 pieces through the middle:
a_) The bottom piece as seen in picture will cover the battery
b_) The top piece will cover the chipset so make sure you adjust the size accordingly.
4_) *As seen by the picture above, the areas marked with red should be cut off to keep phone features functional (rear speaker, camera/LED and nfc areas)
5_) Now use tapes to stick the foil to your phone.I've marked the spots where I used tapes with blue on the picture but feel free to choose your own.Try your best to not get the tapes/aliminium foil stick out of your phone.
6_) Put the back cover back on, if anything is sticking out try to get rid of it.Mine has perfectly fit in so no one can notice it without opening the back cover.
*If you want to still be able to swap your microSD,battery and sim card, go easy on tapes and stick them only to two edges of each piece of aliminium foil.While it won't be as tight it will still work and you will have no trouble swapping them.You might want to follow the steps below instead if you swap SD/battery/SIM too frequently.
OPTIONAL STEPS (clothing insides of the back cover with aluminum foil)
This makes it more practical for those who swap sd card/battery daily only if you didn't follow the steps above.And if you have followed them, you can still do this to enhance the 'heat sink' further.
1_) Go to substep "b" of step 3 in the steps above and also do step 4.After you are done with them you should now have a piece of aluminum foil identical to the piece of foil we've used for the top (can be seen in the picture).
2_) Place it to insides of your back cover, it should look like this
3_) Use the tapes and stick the foil to back of your cover.
a_) OPTIONAL : See the small piece of foil on top of the camera gap? http://puu.sh/du9EB/5e4e9ff7ef.JPG
You can put the small piece of foil there, the one you have cut from the top piece earlier to make space for NFC connection.This should extend the area where heat is disposed.BUT don't repeat this with the back of the phone and make sure that the piece isn't too thick otherwise there will be a small gap between the back cover and the phone when you put the back cover back on which causes dust to fill in.

Well I actually extended the foil on top of the battery because I'm not using the stock lg one. My battery never goes above 21 degrees anyway and didn't increase with the CPU load either. That should help the battery a little bit but not much

It does help but like I said in OP depends on how you use your phone.
If you play games a lot or if you use wifi and browser with multiple pages open (same goes for data) or anything that heats your phone up also heats your battery up.But if you are the kind of guy who uses his phone for calls, messaging and other small tasks it won't help noticeably.
It is known a hot battery discharges a lot quicklier than a cool battery.Our battery usually operates between 30 - 50 in normal usage also depending on what load you put on it so I'm not sure if it would help with his aftermarket battery but it'll def. help with stock battery especially under load.

Yeah my MPJ battery is unaffected after playing subways surfers on performance at 1300mhz while charging. Im sure the the stock lg battery would have been much hotter since its covered in plastic
The CPU went up to 61 but after I exited the game it fell to 56 and dropping

Looks like it's working After an hour playing GTA on charger the phone doesn't burn my hands ^^ and the battery temp is ~40 Celsius. One thing bugs me though: isn't the Wi-Fi antenna affected somehow by this? I always had a poor quality signal in my room but I'm not sure wether now isn't it slightly harder to connect.
Still, great idea man

So far I didn't notice eny problems with wifi connections on my phone. Although I didn't get connection on satellite using GPS, will try use GPS again at home.
Edit: sadly I have to confirm after removing aluminum foil connected on GPS satelits in few seconds so it seems that foil is blocking GPS antenna or maybe is just on my LG 4x HD.

I thought the same way and tested before applying foil and after, I can say that there is no noticeable difference.I have tested it with Wifi Analyzer (shows strenght in dbm) and results were identical, so were the download speeds and the range it can connect to router at.
I haven't tested GPS since I can barely get any signal in my city anyway.Though I doubt it'd effect it since people mostly use GPS in their cars and it still works despite it.Needs testing though @Sipi1302
Can you be more specific how you did the testing exactly?
Did my own tests and while it does not block the signal completly, it weakens them and my phone failed to get a lock with or without the foils.
Doing some research, it completly blocks off only if it's wrapped up in foil in multiple layers but test it for yourself.
Updated OP.This could create problems for people who use GPS but most apps decide location with location services that use wifi or data to determine it so you shouldn't worry about not being able to receive weater updates etc.

First I needed GPS in my car during driving, normally get locked in couple of second, but this time didn't get eny connection and no satelits. Than when I came home I try GPS again and no satelits visible so I remove foil and have 6-7 satelits visible and lock in 10 second and all that I tested inside my house.

Thanks for letting us know.It doesn't make any trouble for me as I don't use GPS at all so didn't have it in mind to test but it might cause trouble for other users.I've updated 'sideffects' with GPS so people will be warned about it.

OK maybe cutting foil on place were is GPS receiver solve the problem, will see and report back

I did a slightly modified version,i used an aluminium tape,real thin one,and i taped it almost everywhere,and i didn't even need to tape it on the back cover. The temperature drops almost instantly to 34° after using,and i mean in the matter of seconds,never gets hot,and does not exceed 45°

Good idea, thinner means it'll stick to even smallest of the corners but I'd recommend you to not use that on battery as it will transfer heat from chipset directly to the battery.Even while it doesn't touch it will make it heat up more than usual

I was planning to do the same but I have no idea where the gps receiver is.
Btw, using foil only at the backside of the phone with no foil clothed into the back cover gives better gps signal comparably.This is probably due to "faraday cage" effect and well we can just put a piece of aluminum between the back side of the phone and back cover to make sure there is no space between them, acts like a thermal paste in a way, avoiding faraday cage effect (blocks signals off) while maintaining similiar temperatures.

Interesting video.Aluminum would probably increase GPS signal too if placed properly, just need to figure out where the antenna is.I already found where cell antenna is, it's to the right of NFC connectors.While using single layer aluminum didn't reduce cell signal using double layer may have.I have excellent signal in my house so I'll have to test it somewhere else.

yellow-highlighted components are antennas (and a few of them are connectors, e.g. the one under camera), unclear which is which but I'm certain top-right one is cell antenna

Nexus 4; Investigating thermal throttling [HardMod] [v1.2]

Post available in PDF [v1.1]
So it is a fact that Nexus 4 SoC throttles pretty often and even if it does not remove anything to this phone, it is one of its particularity compared to other phones using APQ8064 that are not known to throttle so strongly. So, question is why?
Symptoms
So first of all, what is thermal throttling, and what does it has for consequences for your Nexus 4 ?
Quick explanation is that when a chip (CPU, GPU or in our case a SoC) reach a limit temperature, it will reduce its frequency to reduce heat and temperature. For a more complete description, check Wiki.
Keep in mind that with or without throttling, the Snapdragon S4 in your N4 remains one of the quickest SoC on the market. However, it can affect performances on eavy duty applications like 3D games. Better than a long description, check below graph.

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
So lets try to find from where this thermal throttling does come from;
After having a look at Ifixit teardown, I was pretty surprised by the low thermal inertia of my phone and the heat concentration under stress situations (mainly located on the right of the back camera). It looked to me pretty strange, especially after seeing following pictures;
Indeed, after “mentally returning” the 2 pictures, you understand that SoC is facing display and should be spread its heat on the whole grey frame.
So I decided to dismount my own Nexus 4, and performed some measurements with a calliper. I found the following;
Which is quite a surprise if you consider that the chips height is almost the same;
In other words, the EMI shield (left) may come in contact with the frame (in the 1mm depth pocket) while the APQ8064/DRAM Stack (centre) may remain isolated (no contact in the 1,5mm pocket). This is pretty sad if you consider that the below frame appears not to be plastic material but to be made of light weighted metallic alloy (Aluminium and/or Magnesium) and could be used as heatsink.
I won’t overflowed you with tons of pictures but if you look carefully at Ifixit teardown you will also notice that motherboard is pretty thermally insulated from the metallic frame, while at the same time it is pretty well thermally coupled to the battery with bronze housings/threads and wide copper band;
(Please note the 2 battery max temperatures, 40 or 60°C?)
So what do all these pictures show? That mainboard may evacuate its heat through the metallic bridge to the battery while it ‘should’ evacuate it through the metallic frame.
Diagnostic
After several stress test runs, it seem that Nexus 4 tries to keep its battery below 40°C, so it downclocks from 1512Mhz to 1242Mhz when reaching ~37°C and from 1242Mhz to 1134Mhz when hitting ~39°C, while it may completely shutdown when battery reach 60°C.
So after all these founding I made a small quick tendency study;
So, no need to be a genius to understand what is happening, the “insulated” motherboard spreads its heat to the battery which behaves like a heat capacitor all this through the ‘metallic bridge’. Unfortunately, battery thermal sensor is between heat source and heat capacitor.
The cure
So I first tried to apply some thermal paste (a lot! );
Which lead to an obvious result as you can hardly fill a 0.5mm gap with thermal paste;
So as second try I used a small piece of copper to fill the gap (Pre-installation pictures only for showing copper piece dimensions);
I used stability test to stress CPU and observed time before it throttles first @1242Mhz and then @1134Mhz. Please note that I throttling appear to happen when battery sensor reach 37°C. (EDIT: or when SoC reach 60°C)
As a result I obtained following delays before throttling; (EDIT: Other users results added)
Even the thermal ‘pad’ solution, despite its bad efficiency, induces a significant improvement, which gives credits to previous diagnostic/explanation.
Concerning the ‚copper solution, it seems that it solves completely the shutdown problem;
The asymptotic temperature appears to be below 50°C (it was ~41°C after ~15min).
We can also notice that phone temperature surface is more uniform, and hot spots almost disappeared.
Bottom line
So is it ideal solution to solve N4 throttling?
For sure not, because it does not completely remove throttling problem, but at least gives you much more headroom before it happens (especially under real world applications). Not to forget that the battery is deeply glued to the frame so it may collect heat pretty well, but at least battery sensor will now reports a more realistic temperature and not any more battery PCB one.
It also may increase cooling capabilities, as with this mod, you use the complete surface of the phone to cool down (front, back and even sides as frame goes at edges).
In other words, this mod allows you to use your whole phone heat capacity, which increases time before throttling. Using it with undervolting soft mod may bring you the best results.
I hope this could be useful.
Doing the Mod
_ Careful!!! Disassembly Nexus 4 is not difficult, as long as you keep cool, you have proper tools and enough time. Please do not forget to put back the black plastic cover before screwing the motherboard again, however you may damage your screen! (check Jiia posts)
_ Dimensions of the pocket in the aluminium/magnesium frame is about 15mm x 15mm x 0.5mm (with corner rounding ~0.25mm). The APQ8064 chip itself has smaller dimensions, more in the 13mm x 13mm range. So "perfect safe dimensions" would be 14.5mm x 14.5mm x 0.5mm for the pad, if it is a solid (metallic) one. Be careful and try to keep your shim as flat as possible to avoid any stress after montage. For sure you have more flexibility with a soft one (thermal pad, graphite...).
_ Concerning material; if we remain IRL (forget diamonds!) a list of possible material (with decreasing efficiency), may look likes:
graphite foil, Silver/Copper shim, aluminium shim, (most) other metal shim, thermal pad/paste, thermal tape.
Graphite foil: may give the better performances, but may be difficult to supply (not so expensive, but companies sale usually only big quantities).
Copper shim: DIY may not that easy (0.5mm is easy to bend), but you can buy finish products.
Aluminium shim: relative easy to supply and to manufacture (scissor may work), with very close performance than copper.
Other metal shim: may be the easiest to find (ask your local garage mechanic). Lower performance than copper or aluminium but better than pad (steel family). Check thermal conductivity for other possibilities (Bronze, brass, zinc...)
_ Where to find/buy;
Graphite Foil. or on Ebay (careful, Inches)
0.5mm Copper pads on ebay, or on ebay...
0.5mm Aluminium sheet. also on ebay

While that makes perfect sense, problem and the solution, what if LG actually designed it this way and had their reason to not directly "connect" it to the frame? Either way, nice work for spotting this!
And also which hardware rev do you have? Something like this could be "easily" solved by LG with a different hardware rev, for example with a thermal pad (like the ones in GPU memory and stuff like that).

What about using a .5mm thermal pad as those used for transferring heat from gpu ram to waterblocks?

I think you will get similar results to the ones I had using thermal paste. Pre-applied thermal pad are foreseen to be 'compressed' (they are only thick thermal paste), while the one you can cut with scissors have a 'foam' structure which is not as efficient as 'bulk' material.
At least it may be better than stock but not as good as the copper piece. Why not trying to use aluminium sheet? (light, 0,5mm sheet can be cut using scissors, high thermal conductivity)

Fair question, I also had it; why LG engineers designed it like this (as they are for sure not idiots and that I do not pretend to teach them their work)? I do not know. For me, the very unsatisfying but most probable answer is that a thermal pad was foreseen (there is a dedicated pocket!) but abandoned.

I tried to use not too high resolution pictures, but if you check IfixIt pictures you will notice that both are mentioned.
My guess is that 40°C may refer to long term usability temperature (optimal Lithium battery temperature is ~20°C), while 60°C is more an ultimate 'survival' temperature before you seriously damage it.
You've misread the battery blurb
The picture shows both 140°F and 60°C (which is the same temperature), but not 40°C.

Yes in Caution headlines, but you also have a logo showing 40°C/104°F.
Anyway that was not really my point .

Oh yeah, I completely missed that logo, and I treble checked the image to make sure. D'oh, sorry!
40°C can't be it's max temp, so I wonder what it's referring to...
i cant help wondering that this design was infact intentional.....
especially when there have been a lot of people having issues with yellow spots on the screen when the phone gets hot. This is maybe a reason to keep heat away from the back of the screen where the backplate is located.
i could be wrong though.
Either way, this is some great work by the OP!:good:

Yes for sure, you can do it, but as already said, my guess is that bulk material is better. For a few $ you can get aluminium sheet that may give you much better performances (with two drops of thermal paste).
Opening for the first time a smarphone is quite stressfull, but this N4 is quite easy.

Thanks for thumb up!
I did not knew about these yellow spots and screen problems.
However I would say that with this mod, average screen temperature may be for sure higher, but I am pretty sure that its maximum temperature may be lower as you spread the heat on much bigger surfaces (if you prefer, temperature gradient may be lower with mod).
On last test, after 15min, battery (which is deeply glued to the frame) sensor reported ~41°C, I really do not think that screen may have seen temperature higher than 45°C.
So what is the best for lifespan; 10 pixels @55°C and 1 billion @25°C or 1 million of pixels @40°C ? I do not know.

LG Optimus 4X HD P880 Cooling Mod *Update*

As you already aware, there is a throttling problem with this phone. Really killing its potential.
I blame nvidia for making this chip 40nm and LG, not making a proper desing to dissipate the heat released by the SoC.
At default state, P880 behaves like a 100m sprinter. Fast at start, out of breath after the finish. That "finish" depends on the workload of the device and ambient temperature.
At very demanding games I can usually play about 10-15 minutes before serious lag.
This is not all off it.
Because of restrictive governor policies, some games that run smoothly on two core devices, runs like crap on this device. Default governor disables all but one core when there is load on graphics part. I assume this is also because of the attempt to prevent overheating.
So, the device is not running as advertised. This is my thought.
It seems, without serious underclocking and undervolting, one can not get a smooth experience from this device.
With the end of my warranty, I've started modifying the device. My aim is to keep the phone under heavy load with the highest speed as long as possible.
Before hardware level modification, I've rooted and BL unlocked the P880, thanks to great members of XDA.
I'm currently on stable version of CM 10.1.3. Stock kernel.
From what I've read and comfirm with my own experiments, there are two temp limits triggering the throttling. One is the battery, which is 43°C. Other one is the core or the SoC which is 71°C.
With these limiters, device is reaching its lowest speed of 475Mhz under 10 minutes @ 20-ish degrees celsius room temp. I use stability test v2.7 for achieving this. Under real life circumstances, e.g, games, this time differs between 10 to 20mins.
There is a warning on the battery. Says 40°C max. Isn't that too low for this kind of device? With the help of this software I can increase "temp_throttle_skin" value easily to 50°C. http://forum.xda-developers.com/showthread.php?t=2306980
With more headroom on the battery side, P880 drops no more to 475mhz up to 20 minutes of stress testing with Stability Test 2.7.
https://play.google.com/store/apps/details?id=com.into.stability
At 20th minute, battery was 45.5°C. 4 cores running @ 1000Mhz. Core varies between 67-71°C.
After a small mod of applying some Gelid GC-Extreme thermal compound over the metal piece installed on the SoC, I've got slightly better results.
At 20th minute with Stability test 2.7, classic mode, battery increased to 47.5°C , 4 cores stayed at 1200Mhz and never dropped to 1000 but still hitting 70°C. There is slightly better heat spread over the device.
SoC is not touching the main frame directly. Different from nexus 4, there is a small metal shield covering the Soc and memory. (Strange thing is, metal shielding has a hole over the memory part. There is a thermal sticker on that chip.) Only a small part of the metal shield is touching to the main frame. That is a weird material I've never seen before. Its surface looks like sponge but very hard to touch. Like sand paper. I applied the thermal paste on this material in hopes of filling the small gaps and achieving a better surface but it doesn't help so much. I think that rough surfaced material is not ideal to be there in the beginning.
I think, cutting some parts of that shield piece and placing thicker cu or alu sheet metal will be better approach.
I'm also planning to wait for some time for thermal paste to cure. From my experience with this same compound on the PC parts, it takes some time for best results.
All suggestions are welcome.
I also wonder what's your solutions for this throttling matter.
Here are the pics.

--UPDATE--
First, I want to say thanks to everyone who has send a reply to this post.
I'm back with more modifications and updates.
I wasn't satisfied with my previous modifications which was a simple thermal compound addition.
A proper test can not be done with lack of a custom kernel which has advanced software adjustment possibilities and of course a tool to make the adjustments.
Now I'm on CM 10.1.3 Stable with WerewolfJB kernel v009 [04-29-2014]. Making the speed adjustments with Trickster MOD app. https://play.google.com/store/apps/details?id=com.bigeyes0x0.trickstermod
As for the modification, my first approach was replacing the thermal sticker with a copper plate.
Disassembling the P880 second time.
Notice the touch points of the mainframe.
The metal piece covering the SoC area and thermal sticker removed.
This metal piece between the main frame and SoC is an EMI shield and a heat medium which delays the heat transfer to the mainframe. If you attach the SoC directly to the mainframe, it makes better SoC cooling but battery gets very hot in return. This will eventually make the battery die quickly because heat is the number one enemy of the batteries.
If I could improve the heat transfer from SoC to both the mainframe and metal shielding piece, that might improve the cooling efficiency. That was what I wanted to find out before beginning to mod.
The thinnest copper piece I could find is 0.8mm thick.
0.8mm is too thick for a device which has 8.9mm overall thickness!
I was able to reassembly the device but that put a lot of stress both to the mainframe which has LCD on it and of course the fragile, over engineered, tightly packed PCB of the device. This was a bad idea.
I couldn't find thinner copper plates. At least this small amount.
Final solution came from an old slider style switch which has copper strips touching on each other. I 've found it laying around so destroyed it to get some copper strips, thin enough to use. After cutting to proper size, I've dealt with the corrosion first.
They are 0.35mm thick. I think this is the maximum that can be used without serious concerns.
I've applied thermal paste to both sides of the strips, cut the thermal sticker in half and put the thick part back on to the memory chip. This is the final design before reassembling the device.
I've prepared a test video. 20 minute stress run.
https://vimeo.com/97050916
My settings are stock. 1500mhz max speed with interactive governor.
This is the most torturing test. CPU+GPU test with gaming governor is nothing compared to 4 core stress test.

you could disable the thermal throttling via an app (there is one in themes and apps section)
tegra overclock has the ability to disable (or change) temp throttling, and some of the kernels have removed throttling completely (atleast battery temp throttling, the one at 43 degrees)

Wouldn't that be dangerous? Removing the limiters completely?
Nvidia tegra 3 SoC limit is 85°C. LG adjusted this to 71°C. Maybe this is because of some other parts may be affected with such a high temp. All components are very tightly packed there you know.
Completely removing the limit not seems logical to me.
Operation within or close to the original limits should be achieved.
This could be done with undervolt/underclocking like many of the others did. But I want to get the most out of the available mass of the device as a heat sink.

you could leave temperature for shutdown. on 10a version of our software, LG had put 120c as temperature of shutdown (atleast that's what some people claimed, my device came with 10d), so having shutdown temp at 85 or 90 is safe (plus, i only hit this limit once, and that was with werewolf kernel which seems to have very high mpu voltage tables)
however i think throttling is useless - if you hit too high temperature, auto-shutdown will take care of any potential problem

Why not?
If applied correctly, that may be the COOLEST solution.
Now imagine if someone takes this:
mugen-power-4400mah-extended-battery-for-lg-optimus-4x-hd-p880-with-battery-door (google it)
There is enough room between the camera and battery for this:
sunonusa.com/pdf/mm_fan_catalog.pdf(google it)
Take the blower one. Drill a hole and a side opening to the back cover. Add a thin micro switch. Something like you use with the tip of your nail.
So you only switch it on while you playing and not in your pocket.
Voltage is nearly perfect for direct feed with internal battery. A little resistance could be used. Power connection can be done with thin terminals placed between battery contacts.
No further heat sink modification may be needed. Because, simcard and sd card holders get really hot when CPU is hot. Cooling that part with such a method may be sufficient to drop the temps a little bit.
Feasible? Considering the price, effort and patience... Maybe not. But imagination is always good.
@Flying_Bear
I'll also look into that auto shut down idea. Thanks!
All chips can take up to 250 °C for short time. They are soldered on that temp. So don't worry.

I've reached like 95 C after changing throttle temps using tegra overclock app and overclocking (GPU [email protected], CPU [email protected]) with no undervolts.
It screwed my LCD up for about 30 minutes.Since then I'm using 85 C as CPU throttle temp and 50 C for battery and I faced no problems so far.So there is no point in keeping throttle temp at 71 C.I barely hit 80 C after undervolting anyway.
I'm pretty sure LG did this to keep the battery from runing out, not because it would actually damage any components.
+ New updates and a test video added to the original post.

Phone heat and GPS usage.

Noticed my phone gets a little warmer (more than luke warm) than I'd figure would be generated from using GPS (Waze). My previous phone, an S2, was not as warm as this.
My only fear is with all the reports of glass cracking on its own, that the heat may influence this.
Cheers

I think the heat comes from the mobile data transfers rather than the GPS module, is your phone set to use LTE? If so, try set it to use HSDPA instead, see if that generates less heat.
I doubt that it's getting hot enough to have any effect on the glass though.
I've been using MapFactor Navigator for say 5 or 6 hours continuously and my front (and back) glass are still in perfect condition. I'm anyways not willing to restrict myself in using the phone by any means. If the glass breaks then it breaks and Sony will get it back. However, I don't think this really is a general problem.
As degraaff suggested it's not the GPS.
I've run my GPS for 4hours straight (strava) while listening to music and just lost 15% - thats in no way enough to generate enough heat over that long period.

Thermal paste mod for g4

Lg g4 thermal paste mod
This is my guide for applying thermal paste or pads to various parts of g4 to help disapate heat better.
i personally use Arctic silver About 12 dollars american at any radioshack.
1st of all I am not holding a gun to your head, Im not forcing anyone against there will if you are not comfortable tearing down your phone,
dont!!!!!!
In recent events of loads of g4s bootlooping.
I want to say i have a 10/15 g4 hardware rev 1.1 have had it nearly a year and so far no loop.
Prob wishful thinking but I want to say this may be why helps get rid of the heat off the old girl.
3 screens later, 2 camera lenes, and a leather back. still rooted on zv6 So up yours LG.
So lets get started
1st remove back cover and in my case i have a cell phone repair kit with the screw drivers and prys. Remove all the screws in the frame assambly. There are 11 of them.
2nd carefully pry the rear frame apart from the screen assambly.there are no wires to disconect yet. Do not force her apart she will come apart when all the clips are released.
3rd once the backplate is free there are 3 wire clips 1 on the camera one next to it for the light sensors and down near the bottom rite under the battery.
4th you can leave the camera module in just move the three wires slightly to the side and carefully remove the board flip it over and again carefully pry the big tin away from the board.
5th im a little eccentric so i applied the paste to all 5 chips underneith the tin just a very small dab goes a long way see in pics attached
6th when putting the tin back on make sure its lined up on all points.
this is also a common ground connector on most phones.
From here just reassmble and enjoy!!!!
Whole procsess took about 20 min
Before I started I was at 45 Celsius now after moderate usage to check temp 29 celsius.
Ive run the piss out of this phone. sold it twice and got it back wireless charge.
Shes a soldier.

Yea i did a small smudge on each then i put the cover back on arctic silver is a pretty nonconductive paste i try not to put it on everything all sloppy but ive never had it liqufy and run any where either some people say it does i didnt put none on the frame or cover.

Yeah, I really like how the G4 feels and the camera is nice. But temps are crazy. LG seems to have really failed on that front, not to mention how it's all locked down now.
My G2 has been great for that last 3 and a half years, replaced the screen 3 times, battery is now failing though. I'll prob grab another screen as it's just a great, reliable device.

Yeah, I'm not one for benchmarks either, but it can give an idea of the health of the hardware. I did notice lower scores on some G4's I think it may be because of throttling due to overheating though. I get around 70,000, if I put a little pc fan next to it, it gets 71,500.

Nice video. Summary of procedure:
1) open the phone to reveal the circuit board
2) remove the large metal shroud or plate covering the processor chip and memory chips
3) cut out and remove a section of the large metal shroud that would normally cover the processor chip
3) get a piece of "heatsink tape" (e.g., thermal tape, he uses a tape with copper on top and adhesive on the bottom) and cut it to fit on the top of the memory chip, apply it to the memory chip
4) replace the large metal shroud over the chip - this covers and sandwiches the thermal tape on the memory chip under the shroud, while exposing the processor chip due to the hole you cut in step 3) above
5) apply another section of large thermal tape over the exposed processor to extend beyond the processor to the sides, covering over the metal shroud too (*this I disagree with, see below*)
6) apply a small section of thermal tape over the metal shroud located where the memory chip is located
Disagreement issue: there is a gap/divot over the processor, which will no longer make stiff contact with the frame when you assemble the phone. You can see the divot around 13:00 of the video, how the thermal tape "dips" in over the processor.
To fix, I'd add step between 4 and 5:
4.5) apply a small section of thermal tape directly over the naked processor to serve as a shim - just copy step 3) by applying the same procedure to the processor, not just the memory chip
By giving the processor the same covering of thermal tape as you did the memory chip, you will make sure the tape from step 5) that lays across the metal shroud and processor, will now be flat and not have a divot, to ensure good pressure/contact between the frame and the processor when you install the frame

A little worried about my device...

Hey there, i just recently bought an lg g6, and ive been rlly enjoying it. Recently i had to leave my phone in the glovebox of my car ( it was turned off) and the weather outside was 64c outside, and im guessing even hotter in my glovebox (my car was parked in the sun), so should i be worried about any damage to my phone, and can i keep putting it there because its the only place i can put it cus of where i work..
I don't think you have to worry. The internals of the phone itself can withstand high temperatures, with processor temperatures/battery creating a lot of extra heat, so that is factored in. As long as the screen, etc is not in direct sunlight, you shouldn't worry.
Ideally though you'd not want it to get too hot to preserve the life of the battery... but with it being "off", that may not effect anything.
An easy enough solution though would be to get to a sun visor and point the reflective side out. This will reduce cabin temperature and protect not only your electronics, but will keep your interior in good condition as well (especially if the rest of your car is tinted). Just buy a decently thick one. I use one with a nice matte on the other side. Once you get used to using one, it takes only a few seconds to remove/replace.
You can reverse it in winter to keep your car cabin from getting too cold as it will allow some extra heat in.

Yeah thank you i will definitely do that, i was a little worried about the battery and screen but it seems like i shouldnt be worried, thanks alot i appreciate it!
I would also be careful because people have reported with change of temperature the camera glass have cracked. Example is going from air conditioning into the heat or vice versa.
