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 )

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

In Taiwan, someone used this way to preventing the heating:

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.
I've had my M5 (E5603) for about a month now and my CPU temp peaks at around 60-70°C (140-158°F) according CPU Monitor during heavy use (eg. intense gaming or extensive 4K UHD recording). Not once has my device thrown a warning at me or shut down, nor has the performance been affected in any way. During normal use, temperature stays somewhere between 40-55°C (104-131°F). Battery temperature always stays below 40°C (104°F).
So, I was wondering, are these temperatures normal? Could any harm befall on my device? Besides being a tad bit too hot to hold on the back and also the front, it doesn't seem to be causing any problems.
Anybody?
Yes these temperatures are normal. Don't worry.
If cpu temperature is above 65 celcius it is little bit not good. Temperatures of cpu between 55-65 celcius perfectly normal for a waterproof phone.
Don't worry.
M4 aqua heated to 65-80 celcius in it's intial firmware.
This forced sony to release the m5 to cover up the problem in the m4 aqua. ? ? ?
So overheating fixed on m5.
Basically, this is why it is waterproof, so you gotta put it inside water to get colder
(as I have fount everything is normal)
Just wondering if its normal for the temp sensor to read 160c+ in -10c weather.
This happened when i was walking home. Cpu reports extremely high temp and just wondering if this effect any performance.
Bell, htc 10, boot unlocked, S-OFF, 1.90.666.4
.....
Wondering if it's a false reading. Can you download another app that monitors CPU temps and see if there are any discrepancies between the two apps?
Sent from my HTC 10
Wow,that's really interesting. For my information, are you holding the phone in boiling water?

Probably a false reading. Your battery is too cool for a cpu this hot. Also cpu gets permanently damaged at temperatures this high. Either a sensor is damaged or app giving false reading.
that's because of the minus 10°C outside ^^
This has happened quite a few times for me when i used the phone in the freezer.
the CPU sensor somehow doesn't handle minus temperatures very well. Because the battery is constantly used it heats itself up and does not go into minus temperature.
The SoC itself is often in DeepSleep or almost idle. So it doesn't draw that much power, not enugh to keep the temperature over minus degrees, especially with an aluminum body that sends the complete outside temperature inside, not isolating like glass.
Don't worry about it
If you're curious you can install the app Stability Test https://play.google.com/store/apps/details?id=com.into.stability
It heats up the CPU pretty fast, then you can find out what's the lowest normal temperature the sensor can recognize ^^
P.S
You probably cannot damage a CPU due to heat. On my old Xperia Z2 i tried to disable ALL Thermal throttling, and run a Stresstest, when the CPU temp reached 91°C the phone simply shut down. Emergency shutdown to prevent overheating damage. Not sure if it's from Android or CPU hardware protection.
Most Intel CPU's do have a hardware protection, wouldn't be surprised if Snapdragons had the same.

with no OC (AKA 2GHZ + 1.5GHZ) I got 81c, with 2.2Ghz + 1.7Ghz I hit 92c but it kept going with no throttling
95c, i made a video

If you do that next time can you do me a favour and get the dmesg?
If you want to you can "dmesg | grep [THERMAL]" to make it smaller.
Hi All,
I'm using my Z2 since 2017 Jan. I've unlocked the bootloader after a year (non-treble), and since then I've used AEX, Bootleggers etc. Last week after i've switched to carbon rom, I've noticed heating for normal usage. Normal multitasing (Facebook, Chrome, 9gag app) = 45-55 degrees of Celsius. I've switched between a couple roms, no change. This is when I've decided to start over - ZUI 1.9 - bootloader lock then 3.5.X for the baseband, then bootloader unlock, new TWRP, Treble this time. I've tried AEX 5.8 and now ArrowOS, but no change, when I wake up the phone 30-32 C, then when I open something up 40-45-47 very quickly. Is there a way to fix this, or maybe I have HW issue?
Thank you
Try using the sun cooling mod

Sorry to contradict, its not heating, its warm, but not something you can call hot.
Facebook, Chrome, 9gag app

I haven't used 9gag, but both FB and chrome aren't quite resource friendly to start with.

The issue is more or less same here too.. When I am using my Z2 Plus outdoor under direct sun light and Indian summer. Even basic idle phone calls would warm it up. Playing PubG outdoor under sun light feels like holding hot metal and burning my fingers.
Is there a way to fix this

There are thermal mods available for aggressive throttling of CPU for achieving lower temps. You may also try using a kernel which supports editing on fly, like nameless (using kernel editor app from play store) to underclock your CPU / GPU for less heat.

Are you mad or what? 45-55 degree celcius is very hot.. my phone is always under 40 even under sunlight with extensive video playback and browsing and around 45 when playing pubg.. this is what i can call warm.. not 45-55 with light use, i suggest to use characteress's thermal mods to cool down your phone

Pardon me for being a noob, but I am unable to understand how can a software cool down a phone below ambient temperature?
I am from a part of India (Kolkata) where often Ambient temps hit 45c outdoor !!
Some input would be really helpful.

I agree that ambient temperature plays a big role in device heat management, but software(thermal configurations) play a huge role in regulating temperature, you can experiment yourself, just underclock processor in kernel adiutor to about 1.8 ghz and heating will be reduced significantly, our device has sd820, which is known to have heating issues in many devices. It's a quite powerful proccesor(2.15ghz) , so when all the cores are performing at their highest (like when playing pubg) ,heating is bound to happen . So by underclocing to 1.8 ghz you can reduce it. And regarding thermal config files, they are just files that throttle the performance of the device when it's heating, to cool down, sure your device's performance will take a hit, but this will cool down your phone

Thanks for the long reply. But being a noob it seems I am still unable to find the answer for my question.
How can a software cool down my device below ambient temps?
As far as I know, no software tweak can even push device temps below ambient. And ambient being 45c, device will for sure run a few deg over that. No matter how much tweaking is done.
So not sure how I am "mad" for calling 45-55c range normal !!
I've been using this phone for quite a while now and have been loving it on OneUI 5.1. But the one issue I have and can't seem to chase away is the awful heating issues. My phone heats up to 40C for CPU and 35C for battery even while using the least intensive applications such as reddit, Whatsapp, Youtube and even Telegram or during light multitasking and up to 45C for CPU and 39C for battery while gaming. The heat gets so bad that it's very noticeable on the surface of the phone and is a massive inconvenience most of the time. Does anyone know if this is normal? Do I need to take it to a service center?
Note: (These temps were measured using CPU monitor and AIDA64).

I don't think that's normal, but when I updated to OneUI 5.1 my temps did go up. I didn't measure them, but I sure did feel them.
What you could do is download Good Guardians and install Thermal Guardian, then slide the temp -2°C (left). Also, don't keep GPS enabled or nearby scan if you aren't using them, and try selecting the Standard option in Game Optimization from Game Booster app.
Debloating also helps, especially uninstalling Facebook (and its apps) and Bixby (if you don't use it).
Clearing the system cache and repairing apps may help too. I hope these tips will be helpful for you.
