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.
[LG Optimus 4X HD] Sipi1302:
OK maybe cutting foil on place were is GPS receiver solve the problem, will see and report back
[LG Optimus 4X HD] josip-k:
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° :)
[LG Optimus 4X HD] ottomanhero:
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.
[LG Optimus 4X HD] ottomanhero:
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

[LG Optimus 4X HD] Flying_Bear:
gps antenna is probably somewhere near headphone jack, since our phone completely loses GPS signal if you plug in headphones
[LG Optimus 4X HD] ottomanhero:
Thanks :) , I'll wrap that part in aluminum and see if it is.I already have done that for below the battery part and gps signal wasn't effected noticeably while top part made me lose signal to most of the satellites.It's probably there though since cell antenna and headphone jack are close to each other and there is literally no other antenna visible on that picture.In the guide aluminum foil is applied to that part so it's probably there.
[LG Optimus 4X HD] Adam77Root:
Mine is probably among the few that doesn't. :D
[LG Optimus 4X HD] ottomanhero:
So I narrowed down the spot where gps receiver is possibly at by wrapping different spots of the phone with quad-layered foil (completly cuts off the signal) and changed the design accordingly.

I get a gps fix and I can say that there is no difference in connection quality now.Tested by a window with phone being held vertically (since most people use GPS in cars with phone being held by a phone holder vertically or w/e you call it.)

I tried to keep the foil close to chipset itself but for no appereant reason LG put the chipset next right to GPS antenna so had to cut a few pieces of aluminium off.

I'll update OP in around 10 mins with screenshots/updated guide
[LG Optimus 4X HD] ottomanhero:
OP updated with new method/guide, gps now works perfectly without any loss in signal quality, cell phone signal should also be stronger now.

Thanks [MENTION=4149511]Sipi1302[/MENTION] and [MENTION=3506654]Flying_Bear[/MENTION] !:good:
[LG Optimus 4X HD] LGaljo:
So this is our motherboard:

The GPS module is on other side of camera, right above vibrator ;)

GPS antenas are right above volume buttons (two white pieces) according to service manuals ;)

Picture from manuals:

I deserve a thanks for this research ;)
[LG Optimus 4X HD] ottomanhero:
Thanks, that's a detailed research you've got there :good: So those white connectors by the volume buttons are pieces of GPS antenna.Good thing it's not too close to the chipset

So the new method was less effecient at cooling both chipset and battery and I gave this a try:

The battery heats up more through the circuits than the foil can heat it up.So I just connected bottom foil with top foil and battery / chipset both are cooler now even after hours of gaming.Our battery seems to have a little bit of environmental protection against heat (still receives heats via circuits) so I'll update the guide.

Thanks to [MENTION=3693461]DeHuMaNiZeD[/MENTION] for noticing this :good: and I was wrong with chipset could heat the battery up via foil :silly:
[LG Optimus 4X HD] LGaljo:
So this is how my heatsink looks like, I have used alu foil with adhesive:
[LG Optimus 4X HD] bobbiac:
http://www.frozencpu.com/cat/l2/g8/c487/list/p1/Thermal_Interface-Thermal_Pads_Tape.html?id=ZKzSiKdF

Maybe just a good old fashioned thermal pad? Has any1 tried:

Go to hardware store, get aluminym HVAC tape. Tape to back cover so it faces phone.

Use exacto knife to make cutouts for antennas.

In places where transmission of electricity maybe an issue, use an insulating medium, such as ceramic thermal paste.

Place thermal pad over battery, etc

Put cover w/tape on it on.

If issue persists, replace pad w/ceramic thermal paste and add a pad on back of phone. Get some normal duct tape to keep it adhered. (Fan of the camo tape.)

If all else fails, machine an alloy battery door.

[LG Optimus 4X HD] ottomanhero:
Thanks, I couldn't figure the gps issues if it wasn't for you guys :highfive:
[LG Optimus 4X HD] LGaljo:
In this config NFC doesn't work :( Probably connectors doesn't touch each other...
[LG Optimus 4X HD] ottomanhero:
Yes probably. you seem to have used 3 layers of foil and one layer alone looks thick, that might prevent the connectors from contacting each other.Try to taking one layer off and then test NFC, repeat this and see how many layers you can have while keeping NFC operational
[LG Optimus 4X HD] Crescendo Xenomorph:
This GREAT GUIDE also work on Note 3 and Note 8.0..... ^^

I use 4 sheets to make it better in collecting and dissipating heat. Now the heat from SoC is distributed evenly across the back panel....

Maybe copper sheet can dissipate heat faster than aluminium?
[LG Optimus 4X HD] josip-k:
Copper sheet would dissipate heat faster,but it would cool down slower than aluminium.

Trust me,im a mechanic :)
[LG Optimus 4X HD] Crescendo Xenomorph:
I do trust you... ^^

As the Note3's back case is close fit to body, I attached the sheets to the back cover using small double tape just to make it non-movable...

And 4 sheets seems the maximum I can add before I unable to close the back cover... :P
[LG Optimus 4X HD] IcanhasLG:
In a word 1 degre.. just use regular aluminum tinf foil.

MOD EDIT by [MENTION=3843529]gregbradley[/MENTION]
[LG Optimus 4X HD] ottomanhero:
I suggest you to ease off with the sheets.They can block your mobile network, gps and wifi signals.As you can see in the OP we had problems with GPS due to using foil in areas where gps antenna was located at.The only fix is to avoid those areas and I don't recommend more than 2 layers of foil as it wouldn't change much and would potentially cause problems.

Good job applying it on a different device and thanks for letting us know that it works :)
[LG Optimus 4X HD] matthewstate:
Does adding more sheets really help that much?
[LG Optimus 4X HD] ottomanhero:
Yes, there is a considerable space between the back cover and phone's back in most of the phones.Apply some pressure on your back cover and you'll notice it goes in by a bit.More sheets mean less space between them two which then results in heat getting transfered to back cover quicklier than before.

Without the 2nd sheet heat dissipation wasn't good enough in my phone.Like half of the cover's top part would heat up, other parts were cooler so I recommend 2 sheets.
[LG Optimus 4X HD] matthewstate:
Ok thanks ive got 2 layers of foil with an extra piece in the middle but not using any tape :p
[LG Optimus 4X HD] Streetdragon:
I tried it with my p880. I made it like the OP did. 1 layer foil. My connection went prety bad. My Wifi too. But the heat on the chip was very nice!
[LG Optimus 4X HD] matthewstate:
Does this affect Bluetooth music streaming?
[LG Optimus 4X HD] ViniLima:
That works flawlessly! The frying pan is not a frying pan anymore! But my Wifi signal was bad after I made this heatskin (Idk where is the wifi's antenna). I did it with 3 foils.

I have one question: shouldn't I cover the bottom of the phone (speaker's section), right below the battery? Or just uncovering the speaker is good enought?
[LG Optimus 4X HD] ottomanhero:
You might want to make a bigger gap for the speaker, uncovering the speaker is fine.

Even though I didn't experience any problems with wifi at all nor any drops in signal, I researched deeper into this and appereantly the left side of the camera has Wifi antenna.So you should avoid using foil at left/top of the camera for better signal quality.This also applies for bluetooth.Rest of the antennas are already uncovered if you have followed the guide correctly.

(top picture shows the antennas)

Guide & Picture updated accordingly
[LG Optimus 4X HD] ViniLima:
Thanks for the reply!

I've watched this video, from LG Service, making my research: LG-P880 Disassembling and assembling. They call that lower part as "Main Antenna" (image attached). I don't know if any antenna really exists there...
[LG Optimus 4X HD] ottomanhero:
I doubt that info is correct.We know the locations of GPS, bluetooth, wifi, cell, NFC antennas.There is nothing else left.

If you still can't be sure, google P880 service manuals.That is where I got Wifi antenna's location from
[LG Optimus 4X HD] elad.g:
Heatsink_V2_WIFI_FIX

After some digging and cutting and testing......

I was able to get rid of the Wi-Fi and network issues.

Now everything works great + my phone doesn't burn anymore :laugh:

Here is my design based on ottomanhero great idea.

Used 2 layers of adhesive aluminum,

Between the 1st and the second layer I've connected the upper part and the lower part with small straps, repeated that after the second layer.

Enjoy....

These have been taken while Antutu Stress Test was running.

In the middle of the test.

Near the end.

No throttling.

Please let me know what you think.
[LG Optimus 4X HD] ottomanhero:
[MENTION=5861955]KSH2014[/MENTION]

Nice results, you should try undervolting a bit for lower battery temperature or maybe buy an aftermarket one.Would help with battery life under load

Uh well, that's pretty much what we've done in the posts above, plus OP was updated so..

Does the bottom part have anything to do with network? :confused:
[LG Optimus 4X HD] elad.g:
I didn't noticed u updated the OP with the WI-FI solution, so…. :D

Anyhow, i didn't touched the bottom part from the start because i saw some ware it marked as antenna or something like that.

What i can tell you that the reception problem came from the upper left side (or the right side in your phone)

And to be more specific, in the area around the camera (it can be between the cam to the flash or between cam to SD or maybe above, i can't really tell) what I can tell that now it works good.

I hope it helps...
[LG Optimus 4X HD] KSH2014:
Forgot to say, these results are from my custom modded device which I've previously shared the making process.

1700MHz is not my daily speed preference. When using in normal speeds and governor, which are 1500mhz core and interactive governor, I get much lower temps than these, of course without any throttling at Antutu stress test.

Antutu stress test is not a very demanding test but good for simulating "real life" average load on the device.

For me, throttling is the real problem for a good smartphone experience.

From the trickstermod screenshot you have posted, I can see the throttling had kicked in. Throttling is there for keeping the device cool you know, so when modifying for cooling you should measure the time difference of first drop from 1500mhz. Did you notice any improvement at throttling time?

I'm asking because, if this method is good enough, it may be a super easy alternate to what I've done before.
[LG Optimus 4X HD] ottomanhero:
[MENTION=5861955]KSH2014[/MENTION]

Just so you know, most custom kernels got rid of throttling.In my case I had no throttling aswell, using mourta kernel.

It might be that the tasks I've done weren't demanding enough (antutu stress test doesn't use 100% cpu at all times) but I can say that with custom kernels that have throttle removed, your phone will

only reboot

if it gets too hot, no throttle for battery nor chipset

Edit : the low temps were probably the result of the kernel I were on having problems with scaling, a kind only a few experienced so far.

Just checked your modification, good work :good:

And yes, I aimed for simplicity with this method, using foil etc.

You might want to clothe the back cover with foil, use thermal paste wrapped up in foil to make the heat transfer between the two.I'd post this idea in OP but I haven't attempted it yet as I don't posses a thermal paste and I don't want to post untested ideas.This idea was mourta's originally

Though I tried something similiar before by putting quad layer of foil on top of SoC part on back of the phone and it did actually help a lot.I'm having a good number of exams this week and the upcoming so I won't be able to test it thoroughly but feel free to do so.

I think no matter what LG did, they couldn't prevent or reduce the heat transfer between chipset and battery effectively, causing them to heat up together.Yes, batteries get hotter under load but it does not stay at a stable temperature, instead rises slowly up until the chipset is cooled down.Only way to avoid this is to get chipset cool enough or perhaps a way to reduce heat transfer between two (which would be more difficult compared to first idea) Maybe modifications can be made to that EMI shield.Though I have no idea on what could be done about it

And the fact most aftermarket batteries which claim environmental protection operate between 20 to 36 C kinda proves my point on chipset heating it up.

I think the focus here should be reducing battery temperature as much as possible as throttling can be removed/edited to have higher values.It is the main factor that effects battery life and it is what p880 users want the most.
[LG Optimus 4X HD] ViniLima:
OK, after last update, my phone is cooler with a excellent wifi signal. It's summer here, very hot (30~35°C) and the CPU temp doesn't go beyond 62°C while playing games. Last year I was burning my fingers trying to play Dead Trigger 2, always on 75°C, throttling cpu to 475 MHz... Bad times...

Any idea where the antenna and stuff and located exactly on a xiaomi redmi 1s?? I'm so willing to give this a shot.
[LG Optimus 4X HD] caesar170988:
im not using this phone anymore , got a g3 .

why not try to connect the soc to the midframe ? i think some thermal paste or a pad might do the trick . i noticed the metal under the battery is not hot when the soc is boiling .

when battery sensor says 42 C its barely warm to the touch so i guess it has good insulation and wont be affected by a hot frame

L.E:

Stripped the phone , found a metal guard over the soc and nvram , it had some stickers on it maybe for thermal conductivity . put Artic Silver Ceramique 2 on the soc , nv ram and power management chip , put the metal guard back on and put AS C2 on the midframe where it would touch .

I now get no throttling after 5 mins of stability test with cpu at 100% , temps are down cpu 65 C >> 58 C and battery 42 C >> 39 C . Also temp drops fast after stopping the test .

This was done fast and sloppy to experiment the concept . maybe with better thermal compound or a thermal pad more can be done . got pictures if anyone is interested .

I was also using aluminium foil on the back in both cases . Now the foil does not get hot .

I may appear a little simple but I have just rooted my Samsung Galaxy S4 (GT i9505). It's vodafone (don't know if that matters). I want to install a kernal to overclock etc and custom ROM, but talks of bricking if you use the wrong one has frozen me and I need to know if ANY ROM/kernal that is compatible with the i9505 will be ok.

Hi,

I'm not sure what you mean about the bricking, but I do know that if you flash anything not designed for your exact device model, yes, you can and likely will brick. So just be sure anything you want to flash is for your exact model number and that you follow the instructions exactly.
