LG G4 heating - G4 Q&A, Help & Troubleshooting

Hi,
How much does your LG G4 heats up? is it constantly warm even with low-moderate use?
Please share your experiences so far!

Mine idles around 30C, hits maybe 35 under heavy CPU load, and gets up to 40-45 while charging (especially when using the fast charger). It's warm enough that I put a small fan in front of it while it charges (heat is bad for batteries) but otherwise I don't really notice. This is Canadian model (H812), rooted and XPosed, but no mods to thermal systems.

Mine (LG H815-AR) does not seem to overheat on idle or charging but when I play a game it heats a little bit. Specially on Smash Hit, that does not runs smoothly as it should (a slight frame by frame lag sometimes). That is incredible, on my LG G2 Smash Hit was a real Hit! No heat and no lag at all... Software update needed or Qualcomm problem?

mine gets to 42-45 when playing (pretty fast) , usual is 30-34 . living in a hot country though

Mine is @30-35 in idle, in games (Dungeon Keeper in particular) can get to 60-65 which is hot, but nothing to worry about...

I had same issue, so after trying all the available internet fixes including factory reset, I decided to mail to LG, PFB their reply (guess heating up is just fine unless you want to burn your skin )
-----------Reply to Customer Enquiry------------
Dear Customer,
Your phone is an electronic device that generates heat during normal operation. Extremely prolonged, direct skin contact in the absence of adequate ventilation may result in discomfort. Therefore, use care when handling your phone during or immediately after operation.
If your phone sometimes heats up than usual, there isn’t cause for concern since the device is functioning normally. For example, your phone may get warm when you’re using on Wifi Or Unstable 3G network Connection.
The Reasons why your device may get warm are
(a)Playing videos, games, or other media apps.
(b)Tethering your device or using it as a Wi-Fi hotspot.
(c)Using the phone while it’s charging.
(d)Downloading or uploading a lot of data over 3G or Wi-Fi connection.
The Ways to prevent your device from heating up are
(A)Keep your phone away from direct heat or excessive sunlight.
(B)Avoid keeping your phone in enclosed or poorly ventilated areas where heat can easily build up.
(C)Don’t use a case or cover that isn’t made for device .
Or
(A)Try by Simply closing the applications that are running in background
(B)Pause resource-intensive features or apps until your phone cools down.
Your phone is an electronic device that generates heat during normal operation.The actual reason for this concern is the extremely high resolution LCD used in this phone.
The Quad HD IPS display provides with four times the pixels of HD with a superior pixel density. You can see sharp, detailed imagery on screen with an advanced pixel structure that provides a near infinite contrast of deep blacks and bright whites as well as more accurate color reproduction.
Due to this Quad HD LCD, battery drainage will be more as compared to other models & hence battery backup will be lesser & due to high data processing , more heat will be generated.
Higher resolution results in increased data processing and speed of GPU, CPU, DDR memory and etc. All of these factor in power consumption increases the temperature of device also.
This heating is absolutely normal & will cause no damage to the phone.
Also The phone has a inbuilt thermal protection, which reduces the CPU usage, brightness etc when the temperature increases.
Do register on their site and ask them all the queries to be sure its not a defective piece. Mine seems to get fine with the day by day usage, not sure why though
Regards
SK

In Taiwan, someone used this way to preventing the heating:
link.
But I used closing 2 cpu core to prevent it, because the warranty...

I used to do that disabled 2 Big Core and or lower clock to 1.5Ghz.
But since I installed CTT Mod....I don't have to do that. Its Run Cool.

[Q] "High temperature" auto-dimming phone.

So I've got the E970 (AT&T's model) and it apparently does not light staying cooled down.
When doing modest gaming, and even surfing the web I get this lovely message:
"Unable to brighten more due to high temperature. Try again later."
That seems rather depressing. Considering the phone is great. The screen, that is wonderful and I like being able to have my screen maxed while charging or whenever. If the screen is pretty, I want to exploit that, after all.
One thing I've noticed, This thing is constantly sucking a gig of RAM, even when idle.
Anywho, has anyone else experienced the heat issue? This is the second phone I've received with the same issues. I'm trying all methods possible to keep it and fix this issue rather than just taking this one back again and getting a One X+
Seriously, any advice or direction would be pretty awesome.

IMHO, Heat should be normal for quad-core mobile devices. My Tegra 3 tablet, although all plastic, heats up when using. My LGOG does heat up in heavy use. The reason of the screen brightness threshold is to reduce the increase in temp. If you're rooted, you can also notice the clockspeed of the CPU cores are also decreased to 1.18gHz when it reach a certain temperature (about 40-50 degrees).
On another note, this should be posted in the Q&A Section
Moved to Q&A
Erm... Isn't 28nm s4 pro not supposed to heat up that much? My tegra 3 1.7ghz only scales max of 35C when browsing... Maybe getting optimus g for fun but battery life and temp is so horrible...
Sent from my HTC One X+
Nah actually its not like korean SGS3.
Didnt measure the temp on sgs3, but it feels much hotter for sure.
My phone gives me this message on a regular basis, even under relatively light use. I'm glad that there are features implemented to protect the CPU and other hardware from overheating, but good grief, this gets rather annoying - rather quickly. I haven't paid too much attention to my OS and software to notice if I'm also burning a gig of RAM at all times, but that wouldn't be terribly surprising. I'm running a lot of background stuff, ADW Launcher EX, system monitors that I never check, custom lock screen, so on and so forth...
I will say that I didn't have a single heat warning until I rooted and unlocked the phone however. Perhaps it's completely unrelated as Gabby is saying the CPU will throttle on it's own in rooted devices, but just something I noticed.
Yeah, the phone can't even be used while charging without it overheating. I would love to just be able to stop it from dimming the screen. Quite honestly, is the screen being dimmed even helping with the heat that much? If I could just take that error away and not have to worry about the heat, I'd be fine, honestly.
Someone got any ideas of before / after rooting for the temperature throttling? I don't know why it would change anything but - -

I have suffering from the mysterious heating, did anyone had this problem?

Hello everyone, this is my first post.
My phone is LG D855, bought from two years ago.
I know the S801 will running at 2.5ghz as its needed, which will increase the cpu temperature temporary in an acceptable range.
Therefore, I start thinking the problem about the CPU. Then I used the kernel auditor to force down the frequency and the voltage as low as possible.
But the situation still doesn't changed!! And the most weird part is that heating is not continuously but it will burn up suddenly for no reason and no any sign. The CPU temp has been reached around 62-70 degrees, and YES! You got that right, it is hot like I am using the laptop processor on my phone.
The things I had tried before :
Flashed many roms ( Including various stock roms )
Replaced a few new batteries ( Some of those was already dead )
Changing the CPU frequency and voltage ( Minimum 268MHz @650mv , Maximum 1497MHz @840mv)
Force to turn multi-cores off to 2-3 Cores
Apply some heat diffuser tape inside the phone ( Sorry, I don't know the name of that thing, it is black and the iPhone used it too)
After all these messing
Nothings has changed! Yeah! This phone is driving me crazy!
Imagine that something like a fireball burning in your pocket?
I had been suffering from LG G4's CPU issue enough. I was using the G3 before I had the G4
Because of the quality of the G4's camera, and in that time, my G3 just work very well. So I decided to buy G4 at that moment. But the result just told me I had made a wrong decision.
I just go back to G3 since my G4 was died, and now the G3 works very bad...
I am really disappointed on all LG's phones. I will never go there again.
Yeah first of all this is a messed up phone all over place. Heat and CPU throttling because of heat brings lag to phone. 62-70 Celsius us usually became normal for this phone, in summer it becomes worse. I know some people will say install this install that but there is no way. If you have enough money sell this and buy a new phone but if you don't have money try to apply thermal paste to your phone there is instructions in general section about that. Good luck.

Thanks for the suggestion, but the heat are still there even if I apply some paste on the die, doesn't it?
There seems the problem is just not about the hot air flow won't get out from the device, it's the CPU draining my battery as well, which is mean the heating is just one of those problems. The battery problem is can't be ignored too. When I noticed the phone start burning, I will take it out from the pocket and observe its battery status. And the result is very incredible, it had lost 10% battery life in just 10 minutes!
I had enough money to buy a new one, but just don't want to waste any money on phones until this one die.
I am not a power user or even not a gamer anymore, just used my phone for web surfing or chatting with friends. Although s801 is just way too much performance for me to doing those ordinary tasks, I still keep it for the QHD screen. Those cheap phones, yes, they are already matched my requirement but not included the screen.

People say thermal paste help them to get down heat. The problem is that G3 doesn't have any thermal paste to make cpu cool down. Cpu heat directly goes to metal surface so the phone can't cool down itself and sometimes it's so hard to touch it. If you have some hand skill try to apply thermal paste there are enough instructions and discussion in that thread. Also about battery, G3 battery is awful, it gets broken easily phone keeps reboot itself when battery dies, because it has QHD screen battery goes down easily. Make sure some apps don't stuck in background and eat battery. Sometimes when phone in pocket and idle it gets hot because some apps keeps working in background so make phone hot and eats battery.

Hi, I did a research about the mod that applying the thermal compound on the CPU die.
Many of people say that is effective to reduce the temperature at least 10 to 20 degrees after they tried that on their G3. Since the thermal paste is not pricey, so I can give it a try. I will try to do anything I can to calm this baby down. And in the future, I will never fall into the LG's phones trap again. (by the way the G5 looks very nice, but it still not my cup of tea.)

G3 is the only LG phone I've heard with heat issues.
My old G2 (which is just as fast) never overheated and always remained cool to the touch.
With that said, I just did the thermal pad mod yesterday.
Used some fujipoly 11 W/mK 0.5mm and it worked wonders.
Idle is 35-40C
Normal temps are 45-55C
One day into it and the phone is cool to the touch no matter what I toss at it.
Do the mod bro. 15-20C cooler temps across the board also makes a noticable boost in performance and smoothness.
I really enjoy using the phone like this
D855 CTT mod
1. Thermal paste.
2. CTT Mod : http://forum.xda-developers.com/lg-g3/development/wip-2-12-ctt-mod-marshmallow-testers-g3-t3313870.
I had the same problem. I found a youtube video, watched how to break the phone down, and applied the paste. It was important to use a generous (not an insane amount though) bead to ensure contact with the cpu and the frame. The phone temp at idle dropped ~15 to 20 degrees, and it never shuts down from overheating anymore. I can overclock the cpu with a custom kernel now, no heating issues at all.

One plus 3 heating/warming even after replacement like the old one! is it normal?

when using wifi/4g in my house, i watched video, browsed fb and even shared internet and all. below i'll give my observations:
in wifi:
watching video, fb and browsing, whatsappin: the phone get very very slightly warm like not warm just the bit different from the phones usual temp like it hovers around 33-34.
when gaming in wifi it goes arounf 36-39 (NOVA 3) battery never crossed 31..
4g in my house, battery arounf 32-33, temperature around 37-39 for all.
but when i step out of my house, like when i'm operating my mobile in train/bus and the ambient temperature varies from say 28-32, my phone gets considerably hot and today, i was travelling in Bus and the ambient temp was around 35 and i was just browsing , watching videos and fb, my phone became hot like it even would have touched 43-46! i felt it hot to touch, is this norma(it's making me extremely paranoid)l!!??? if this is the case what happens if it's summer here, the phone would become blazingly hot, coz in summer ambient temp would be around 36-44 and all!!
Is this normala or am i unlucky for the second time ? I'm getting paranoid!
Just hit them back up

Are you serious.... When the ambient temp is 35 degree what else would you expect... Every phone on the planet will get that temperature. Can't believe you had a phone returned for this. You know the front of the device is black and absorbs light... When the sun hits your phone it's gonna heat up also. This phone is the best Android phone when it comes to thermal throttling.

With heavy multitasking, I hit 60+. Not regularly, but it has happened. The temperatures you're hitting are normal for me. I've had zero issues with the device. I have an OtterBox case, so I don't feel the heat as much. Honestly, I barely even notice heat at those temperatures. Considering the fact that the body of the device is aluminum, it's going to easily get hot to the touch.
Also, my One would almost always run between 45-70, and I've had that since launch. Used it heavily daily for years, and I still use it regularly as an app development device. No issues.
These devices have extremely powerful processors. They get hot. There's not an easy, efficient, way to cool a processor in a device like this yet, but they're designed for heavy use, so I wouldn't worry about it.

Hi first of all thanks for the reply.. I'll tell you what really made me paranoid.. Every evening I travel in bus and train and the ambient temperature would be from27-28_29.. I use 4g jio.. I just browsw/fb/insta.. In minutes my phone near the earpiece on the screen gets warmed up and it'd go around 40-41. Then I lock it it cools down fast but when I unlock it in seconds again starts warming up... My friend using same 4g in moto g4plus but his screen is cooler than mine... Please my one last doubt...
This is nothing lol. I live in Scotland so just now ambient temperature range from 5-13 °c and in my house 21-23°c and my Z3+ hits 60-70°c easily on heavy use. Benchmarked it one day and hit 90°c. The joys of the 810 chipset. Anyway away to upgrade to the OP3T so i should see and feel a massive difference.

Install a custom ROM and kernel and limit your background tasks. You may just have a bunch of things running using your CPU.
Thank you all!
Hey all thank you guys very much for replying to my thread! i'm really feeling okay instead of getting paranoid with my phone.. although i'd be very happy if you guys just clear me this last doubt!
today I was playing NOVA 3 connected to wifi in an ambient temperature of 25C, 5-10mins into gaming, CPU reaCHED A MAX OF 41c and at around 20 it maintaining at 43 but jumping sometimes 45.. this is gaming, but i get the same temperature just browsing in knda same ambient temp while I'm travelling. and also browsing in wifi/4g(fb,insta,chrome) in my house in ambient 25-27 gets the phone phone to 35-37... and the rest of the pat of the mobile is cool, even the back side is normal, only the small portion between the earpiece..
why is this happening? is this normal(it'd be great if you guys clear this)? if yup y so? and why phones like oneplus x and moto g4 etc have relatively less temp than OP3..
I know it'd be irritating to answer kinda same question again, but this would my help paranoiac freaking out for my mobile will go down..
thanks in advance for your replies

Because the Oneplus 3 is a lot faster, the Temps you are giving are n even close to hot... This has been one of the cooler phones so far.
Like others said, those temps are completely normal. Hell, I'd even expect them to be higher with your fairly high ambient temps.
About comparison with other phones - it all depends on internals and design. OP3 is made of aluminum so it'll dissipate more heat into the case - you'll feel it better. Other mentioned phones are plastic, so they'll contain more heat inside (you'll not feel so much heat, but the cpu may even run hotter).
And OP3 has cpu located just below the camera, so it's normal that it reaches top temps in that upper center part of the device.
P.S.: You talked about loads and ambient temps, but didn't mention screen brightness - that also plays a massive role in running temperatures.

for me mostly brightness bar will be in the middle... i never use it with high brightness..
Just get a case and maybe a screen protector so that you can't feel it getting hot.

hey ya !! sorry to disturb you again and again.. just a urios doubt.. what'd be the temperature of the phone or how hot can it gets, when u use 4g and fb app in ambient temperature of 29C and 33C..
mine got arounf 38-41 for the 1st cse and around 43 for the second case..
I know i'm being paranoid, ,but please, clearing tis would help stop worrying a bit
All the temps you posted are normal
About Moto g, it has much weaker SoC. A Ferrari's engine gets much more hotter than a toy car. Doesn't mean there is anything wrong with Ferrari
4G /3G active usage can get hotter than gaming. That's also normal

Nothing much to worry here. Even I use Jio all the time. My OP3 get a lot hotter than any other device I use before. Reasons I knew are these.
1. OP3 rock with a high end processor. Say SD 820. Other phones you mentioned are consisting of relatively lower end processor. So internally they might heat up more that OP3 while doing high processor intensive tasks, but the plastic casing keep the heat inside, as OP3 is made up of Aluminum that being a metal heats up so quickly and and u feel more hotter in hands than the other ones and also it cools faster.
2. AFAIK the processor is situated just below the Camera bump. Hence it heats up very quickly at that area. Irrespective of outside temperature.
3.While using 4G network it's obvious that the phonehave to communicate with the network at a very high rate than 2G or WiFi. So it's clear that it will heat up. Also using high processor intensive application like Facebook gives the processor high stress and it heats up in no time.
Remedies
1. Use a case. That somewhat helps in insulating the heat.
2.If possible use WiFi rather than 4G network. That will considerably helps your battery life.
Conclusion.
Don't worry about the warmth of the phone.Its normal. Just enjoy using the phone.
Never Settle.
Cheers.
Clearly never experienced a SD810 device. I'm sure Snapdragon took there name too seriously with that chipset. I could hit HIGH 80°c in seconds playing basic games, using the camera and under heavy usage. Had to tailer my use around my Z3+ but now I have the 3T I can do what I want and it never goes past 50°c so far.

Heat

Some phones are great to take camping because if you play Asphalt 8 long enough, the back warms up to the ideal temperature that can bake bread. Rate this thread to express the extent to which the OnePlus 3T stays cool under extended heavy use. A higher rating indicates that even when playing strenuous games for long periods of time, the phone doesn't get uncomfortably warm.
Then, drop a comment if you have anything to add!
Got the phone today, and it feels very cold to the touch. Most of the heat It gained was from my own hands... though it is winter. I then put a silicon transparent case, and after setting everything up I did some google cardboard vr for around 30 minutes and felt a light warmth through the case... barely noticeable.
Mine is getting pretty warm after rooting, making a nandroid backup, and flashing xposed. Not quite uncomfortable, but very noticeable.
My phone has only heated up a couple of times, and that was when I really used it, games and such.. Otherwise it's really "dead" to the touch.
If you want to heat it up, use some benchmarks, or if you want to be more productive, use mapillary outside and photomap your area around.
Yes.. it's getting heated very often even I use for 5mins.. I got phone today only(23-12-2016). Please suggest a solution.

For me its exact the same thing...
Of course its gonna heat up if your cpu and gpu are working at max speed all the time.. its normal
First day when I flashed custom rom, installed all apps, rooted, twrp and all that it was hot to the touch because the reason above but now when I use it in a normal way its actually cold to the touch most of the times and I love that
I rooted mine and installed a rom really got hot then I changed to a different rom and it is very cool now.
OnePlus 3T is a really cool device. I suggest users to buy it. It has very cool features like Fingerprint access, Camera etc.
But if anyone gets Official TWRP for Android 7.0 for OnePlus 3T, Please tell me*
Never felt any kind of heat through the case (Orzly 2-part case).
Never been an issue.
i have noticed it's evenly warm when it shouldn't be. try enabling "Auto close high power usage apps" battery options.
the description makes me laugh. engrish.
"When it runs, the system auto clean up background power-hungry apps , prevent phone from getting hot."
It doesn't warm up much, if at all, for me, but I am using a rom that underclocks the CPU which could be the primary reason for this.
On 3.5.4 I would have occasional heating after a phone call. Battery stats would show that the phone was using the CPU for extended periods after the call had ended. Usually a deep clean of the ram would solve it. Sometimes it didn't solve and then a reboot would solve the problem. Phone was completely stock.
It was comparatively very cool throughout with the CPU temps being in the mid 20s or low 30s even during charging at 3.4A with the dash charger!

Heating issue
Got my phone few days ago its heating when i am playing clash of clans but otherwise no issues in normal mode.
Nvm
The phone stays cool to the touch even under heavy gaming. (Max 35C on cpu)
Heating hasn't been an issue so far. Had an app causing constant 70% CPU usage and the device was just slightly warm
my phone getting hot sometimes idk why
Any manufacter could make a super cool phone by just setting an agressive thermal profile. Oneplus 3/3T doesnt throttle at all, not with gaming. The phone gets warm, but you have to consider that it's using his full potencial. I prefer a hot phone (not the case) than a cool phone with half of the power the soc offers.

Question Heating up from basic usage

Is it normal for this device to heat up from basic usage (such as browsering and social media).
By heat I do not mean overheating but it does make the hand feel quite warm.
This worries me alot since I get annoyed by phones who get hot with basic usage.
Would this be because of the sd870 chip?
For me it does warm up a little bit during normal use but it's way better than my previous phones, idk maybe my standards of phone temperature is different than y'all. And if it was running a SD888 it would be even worse.

I think mayb the issue is me comparing it to a snapdragon 730g
This was my concern also but in my case hearing was mostly during charging. I replaced the device and so far things are a tad bit better

Charging especially fast charging produce heat.
Charging is an electrochemical reaction that requires a certain amount of heat to charge properly. Oddly Li charging is a mildly endothermic reaction but resistive elements in the cell produce much more heat than is absorbed.
♤Do not use phone while charging as it will skew the charging curve.
♤Listeners to music (no internet streaming) on bt with screen off is generally ok.
Best start temperature for fast charging is 82°F or higher (85-90°F seems optimum on my N10+).
Do not let battery temperature exceed about 101°F while charging, cool as needed.
♤I use a fan and/or a damp microfiber cloth to keep it cool, works well.
Li plating will permanently degrade your battery and can cause outright failures.
Never charge a Li polymer that is near freezing temperatures.
Charging below 72°F or in high temperatures (exact value unknown, some say >140°F but this may not apply to Li polymer) My Note 10+ will stop charging at about 102°F so hence the 100°F limit. In any case temperatures higher than 90°F aren't needed for fast/optimum charging and only shorten the lifespan of the battery.

Nope, miui is chock full of bloatware and make these phone warm up even some basic task. Tried several custom room in our forum, no heat up at all
I think it has to do since its summer too, debloated through but it still gets warm using social if I'm outside or if its under the sun.
From my logic this has 100% to do with a higher end cpu since as I said my sister samsung a71 does not do that.
Mostly worried that the xiomi build quality is **** that's why I asked

Use manual brightness control. Try to avoid going over 50%... and don't use in direct sunlight. High screen brightness increases current drain/heat a noticeable amount.
You're on to something when it comes to brightness... Newer panels that are being used in the latest Chinese devices all have very high sustained brightness. Which is nice and all but no1 had considered how that will play in combination with the newest chips,
If you compare F2 and F3 the earlier model only had sustained brightness of 500cd/m2 whereas the newer model can sustain 900cd/m2 of brightness - that's a huge difference
Then what about chips? Both snapdragon 888 and 870 are dumpster fires ( Even the dimensity chips ) , while the performance gain is insane compared to last gen so is the heat output... And sadly even the gaming devices with cooling fans struggle to keep the chips from throttling. Take black magic 6 pro for a shameless example (snap 888), it reaches upwards of 55C on the phone body itself during benchmarking with no signs or intention for throttling down to save your hands- that itself should be illegal but no1 ****ing cares since how else are they gonna reach those benchmark numbers.... ( 54C can cause full thickness burns in a matter of 30 seconds or so )
I don't have poco f3 to check but from looking at stress tests on YouTube you can see that they are much more conservative when it comes to heat. It reaches only 42C during benchmarking then starts to throttle down and basically hovers around that temp 42C-44C.
The chips are already insanely good when it comes to performance but the cooling is pacing behind... So yeah it's pretty normal that your device is getting hot - so is every other device on the flagship market rn. Most you can do to solve that would be in this order > Get a peltier cooling device like blackshark fun cooler pro > Lower the brightness to what's usable for you and hope it's enough to somewhat delay the throttling > The last one would be messing with the phone itself like downclocking it or lowering the voltage. It's a cat and mouse game , the throttling will come eventually , the only way out I see would be the first option or the last one if you're capable enough to mess with that and are lucky enough to get a chip that undervolts nicely.
Cooling?
Simply use a damp microfiber cloth.
