Just as the title says. My Samsung Galaxy S10+ tends to heat up less when I play heavy games like PUBG while charging compared to when I play unplugged. I have the exynos version on latest stock firmware. My fast cable and wireless charging is on and I only use 4G data (no wifi). To my understanding it should be the other way, i.e. heat up more while charging and playing! Anybody else notice this? Any views and suggestions as to why this would happen are welcome.
In theory your phone would be pulling power directly from the fast charger therefore having more current available. Normally when your going off of battery power playing resource intensive games like PUBG run you CPUs at max frequency causing more heat. When the CPUs run that speed they also use more power sometimes more than the battery is ment to run at continuously causing the battery to also heat up. So using direct power reduces the amount of heat production.
As we see in "Gaming" phones like the ROG branded one they use better cooling methods like water and gas(usually hydrogen) based cooling.

Thanks! Makes sense to me. But this would also mean that it's possibly better for the battery that way (playing while charging). It's definitely heating up a lot less! Will have to wait and see.

Is it normal for HOX to heat up (quite a bit) very quickly when browsing web (Chrome beta)? It usually heats up near camera and on the opposite side. It also gets very hot on charging while using it (much less without usage). Doesn't seem to show performance issues though.
Thanks for your answers.
From what I've heard, I think a lot of the innards are packed around the camera (and that probably means the cpu/gpu)....hence why it heats up when being used intensely.
It heats up if you are using the UMTS/HSDPA-Connection.
Try to surf with WLan or GSM and you will see that it wont heat up that much!
It happens when I'm on wifi. Maybe I can check the temperature somehow? Is there unwanted or critical temperature?
Quick update
The phone seems to heat up less with stock browser.
So far the more tabs/tasks are open the hotter it gets but why is it so hot from the browser?
Still I would like to know what are the temps to avoid?
Do your phones get very hot and in which circumstances?
Flash a custom kernel then use Setcpu to downcloack the cPU if it crosses a certain temp
Hi Guys,
I have been playing Samurai Vs Zombies for some days now and I notice that when I play the game without the charger connected, the phone does get warm but not super hot.
When I connect my charger to charge while playing, for sometime there is no issue and then phones back becomes super hot and the battery indicator ,which is supposed to just give out red indicating charging, will start blinking red greed red green in that order repeatedly...
Does anyone else experience this and why is this?? What does the lights blinking mean???
Does it mean that the phone is overheated???
It means the battery has overheated and it will not charge until it cools down. This has been my top complaint, as it makes HOX unusable for car navigation, car recording or longer gaming (it will just discharge and then die)
WTF!!!!
Then how the hell will we use it for anything while charging.... You open maps and turn on GPS that will also create a lot of heat... Car navigation is screwed up big time...
I think if this is the case the new base 2.05 will serve much better as people have reported that the phone is relatively cooler when compared to the current build..

actually there is a precoution for this by HTC. when your battery is below %20 the CPU clock will be limited to 1000Mhz. the heat comparison between the 1Ghz and 1.5Ghz is 72C and 85C (these are the values i found out after stressing the device in a really hot enviroment for half an hour).. so when the CPU heat is lower basicly the overall heat is also lower and the device will charge itself again..
the good news is you will never run out of battery, the bad news is it will not charge above %20 and something and mosty you will be using your device at 1Ghz CPU speed.. but hopefully this can be solved with a software update (maybe limiting the current or the CPU clocks while charging)
i think the battery choice by HTC was a complete mistake (the one and only mistake the One X has).. it is not producing 5A but or anything, just an average battery but gets hot very very easily without any valid reason.. besides the unibody design is keeping the heat inside of the device.. i wish one day we will be able to replace it with an bigger capacity and more heating-proof one..
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.
Hello, my htc 10 is lagging in games like hearthstone ,csr 2 and generally all graphical intensive games. I dont know what to do,i even used the high performance mode in the developer options but it doesnt seem to do anything.isnt this phone supposed to not lag at all?what should i do?
1) Check if you got any app that hogs your cpu in the background. CPU hogs = more heat = more throttling = lagging.
2) Check if you've put your phone into a thick case, some of these cases will negatively affect the rate of heat dissipation.
3) If you are 100% sure none of the above is the issue, you might have a lower-tier-binning chip (which means to achieve the same frequency, your chip have to run at higher voltage, hence more heat). Then, wait for some guru to make a custom kernel that supports undervolting. No guarantee though, neither on such kernel being made nor your undervolting potential.
4) Try some custom kernel like this one from flar, which do loosen the thermal limit. http://forum.xda-developers.com/htc-10/development/kernel-elementalx-htc10-0-01-t3385167
I have no performance issues running any game.
Have you tried running the games in Boost+?
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.
