Heat - LG G6 Real Life Review

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 LG G6 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!

Basically non-existant even with heavy use. Most of the heater is at the top of the phone. LG put heat pipes that attach to the battery so it's likely this is what reduces the heat substantially.

I have never had a phone that would not get heat under extensive use, heck even my computers do that. People have to be realistic about such a measure and understand how much processing power is being used in a tiny compartment. If you run an engine in a sealed box with very little venting in comparison to running an engine in the open... it's GOING TO GET HOT. People need to understand this and be more realistic when looking for a phone that they think will be ice cold at all times.

The phone does stay cool. I have tried the samsung galaxy S7 Edge snapdragon and it just is terrible once it gets hot. That is important for performance.

It deals with heat much better than a lot of phones. The LG G3 was a much worse offender and overheating even caused some hardware problems for me with that phone. The G6 really isn't bad at all.

Battery died after 14 hours of of google maps, streaming music over bluetooth and recording videos. just before dieing, the Clean Master app showed the cpu tempurature at 42 degrees, with one of those clear otterbox cases on. With the Otterbox off the cpu sits about 32 degrees with med-heavy use

Well, of you try Antutu, the second time you will obtain 100k points and nor 150k as usual.
And the phone becaumes very hot.
Op3T with same processor didn't do it

Hi my CPU runs at 35-36 Deg at idle time when. do some simple tasks such as browsing our watching YouTube it hits 40 Deg and while playing games it goes to 43 Deg that's the max I've seen in the device. I monitor the temperature using the cpu temperature app. I also get a poor SOT of 4 hours max, IDLE Time and to draw too much power

A weird thing is happening with my mobile for the past 2 days. my phone never went beyond 36C even when I use it in direct sunlight sometimes. and my phone felt warm only when i used it in direct sunlight. otherwise no matter what the temperature, my phone stayed very lil warm. from Day before yestrday , during my travel, or when idle. the phone starts at 26-28C, and suddenly raises upto 33. and today it set a all time high going till 39C and the phone felt pretty much warm even when there was no sunlight and the ambient temperature throughout my travel stayed at 25C. i was just seeing youtube videos, for which my phonw never even got a bit warm, today it was high. and even unlocking and replying in fb messenger gets it to 36-37C. what suddenly happened to my Mobile. I'm pretty much mobile. for something which never crossed 36 suddnely going near 40 and feels pretty warm to touch.

Network reception problems / something running heavily in the background / an app was updated and now causing increased CPU usage / phone running too long without a reboot.
First of all, have you tried rebooting the phone?

Guess I did that yesterday and let's see. so you're suggesting the phone should be rebooted once in while? if so the frequency!
and network recetion, I travel through the same route everyday, so the network pretty much remains the same.. and I was usingFB Messenger, how can i know which app is running in the background. and updates, was configured to run only on Wifi, I was on mobile data, so no updates were going on thanks for the response though. Kindly help me, coz this is driving me crazy, this is one helluva awesome phone so I don't want it to go crazy too

Of course, phone should be rebooted sometimes, in order to cancel some cache files produced by Android. A frequency? My suggestion is what suits better for you. In any case at least once every 10/15 days or so, but even less if you prefer.
About network: the fact that you've travelled all day long is probably a reason of higher temperatures and higher stand-by drain, because when you travel you change your position frequently and the phone has to find mobile signal through constantly new antennas, causing it to work often even if the screen is off.
You can find apps running in background in developer options, under "active processes" or something like that. If you want to check if there's something eating your battery in background (and therefore heating the phone too) you can download GSam Battery Monitor and check after a day of usage what's under wakelocks.
Anyway, in my opinion you shouldn't worry about a temperature of 39°C. I think it's completely normal. However, we have a very good heat pipe, and that temperature is just warm, not even close to being called hot, so you don't have to worry about it. Under 65°C (and even more) there's no danger and there's not thermal throttling, this means that the phone runs perfectly fine and doesn't low CPU frequencies.

You're absolutely right! I should never worry about that at all. but the thing is for all the same scenarios my phone became a little warm and never crossed 36, provided that there is suficient airflow outside, if not I'm stable in traffic, my phone irrespective of temperature, it gets sufficiently warm. I cant imagine the same during summer as temp here would raise to even 42C, which eventually will make my mobile more hot. even for simple taks, my phone become, a bit warm, but not more than that. remaining the same. regardless of temperature, my phone is getting warm. the warmness is all I'm worried about. I know this is the coolest phone because, I used to have a OP3 which became way too hot!
the real reason I got worried is that, my mobile went to that reported temp of 39C, anf felt pretty warm, when I was just using Wynk Music App, and watching some pre-stored videos in my sd card through default LG video player and replying to Messages.
AND YES, while travelling today it began behaving even more wierder which i didn't experience in my Oneplus, travelling, pphone locked with only Wynk music player running, and the ambient is 25 and the phone got upto 34C without any usage, unlocking and replying to SMS will make phone bit warm.. and whereever my bus stops idle for a minute or so, the temperature increases inn my mobile.. Why is this happening to me

Gsam says, collective CPU apps, my phone is not rooted

Does anyone else's G6 warm up when using the cameras? It stays cool most of the time but once you switch on the camera and take 1-2 photos, it starts warming up. The battery also starts dropping faster. This isn't too bad with the LG app but it gets noticeably warm with the Google Camera app. Is this normal? Going to buy the Spigen case for it so not sure if it will help with the heat dissipation.
The battery dropping faster also worries me if the phone can be used as a main camera on a trip.

"No thermal throttling" no there definitely is, sorry, I can feel it. Benchmarks get cut in half after about an hour of use. However I think it's rather excessive throttling. Perhaps it's to do with the bootloop issue...

[Q] Excesive heat from atrix

Over the past month and a half that I have had an atrix I have noticed that my atrix has burnt me several times. I have it in my pocket and it just gets really hot. It doesnt seem to be the battery as the entire phone is very hot. This has been happening even before I rooted my phone. It burns me through the otter box. Im reluctant to take this back to at&t as i would have to unroot it. Are other people having this issue?
If its ridiculously hot, as it seems it is, thats not normal and you should return it ASAP. Also rooting would not affect heat output in any way.
One, wrong section.
Check a taskmanager when it starts running hot. Find out what is pulling so much processor load to create the heat.
I had this problem, took it back for replacement, then had the same problem on the new device. It turned out it was the Exchange sync causing the Motorola.services process to run constantly and kill the battery.
I solved it by changing the Exchange sync from push to every 15 minutes. I also do not use any sync with Google (mail, contacts, or calendar). My battery life is unbelievable now and the device stays cool 90% of the time.
Wasn't crossposting restricted in this forum?
Ha. Excessive heat. Buddy at least your phone doesn't have a aluminum battery door. Try touching that when your phone is being overclocked @ 1.5 ghz.
But essentially something that is syncing often is causing your phone to use the radio alot. And since its in your pocket there really isn't any airflow to cool it down hense the phone will generate heat.

Hi all!
I hope my post will help other people like myself that ware looking for information regarding this issue:
I installed TempMonitor and followed the teperateure of the device. There are 2 temperatures to measure: CPU and battery.
I will elaborate my findings:
1. CPU temp at rest without sync (push mail turned off) is 28-31C after a while (depends on the room temp).
In slight effort the CPU temp can get close to 50C but normaly is ~40-45C
It seems like the CPU temp is not that important and only when the CPU is running hot for ~10 minutes you feel the heat and it starts to get annoying. Notice that in this point a lot of battery juice is drawn.
2. Battery temp is also ~28C at rest. It gets up to 35C on ongoing effort. Since it is very large (1920mAh), you will feel the heat. I think that the battery is the main heat factor in the device and the CPU and graphic engine running in addition to the battery getting hot will cause the entire device to feel warm or even hot.
3. I noticed that at the beginning, one corner of the device (lower right) got REALLY hot and REALLY annoying at times. After 2 weeks, the heat spread became more bearable. I think it has something to do with the battery "setteling in".
4. Running apps that constantly check for updates and even push gmail, will cause your phone to run 1-2 degrees hotter and the more apps you add the hotter the phone will get at the resting state. Hence, when starting other apps it will get hotter and faster. even PowerControlPlus which is a very simple widget gets the deviec ~1 degree hotter on idle.
5. As the battery gets drained, it emits more heat. Try to charge your phones and not run battery draining apps when the battery is less than 30% or even 40% full.
I will comfort you all by telling you that I have a few friends with Galaxy S and Vibrants and their devices get hot too. A bit less on normal use like browsing but pretty much the same on 3D games and such.
I hope I helped because I was really frustrated by it for the first 2 weeks. I hope it will keep improving. I also purchased a case and hopefully it will help with the heat spreading around the phone - will update.
Please install Watchdog from the market to check if a process is acting crazy.
In my case it was 'Android media process' which ate 50% of all the processing power. There was not much of a performance drop since it occupied just one core.
Anyway Watchdog will give you an alert in case a process exceeds a certain percentage and from there you can google the problem or uninstall the app which is causing problems.
My Atrix 4G displayed a temperature of 37 degrees celsius. The highest till now I have seen. Could be higher though.
Its a dual core processor stop worrying about heat unless its hotter then 50c

@OP: I think ur safe.
how you turn off the push email? someone can indicate your configuration? thx

When watching youtube I reach 42 degrees celcius in the battery and it literally burns my hand. Would maybe return it if I hadn't ordered it from Canada.

thats because aluminium is a conducter which will let the heat out. plastic keeps it in. so if its hot i wonder why? xD

I'm having the same issue, but it's only coming from the bottom half of my atrix, and only since I installed a new LCD. I'm actually worried the heat will destroy my mem card and sim.
I've ordered a new LCD now, so hopefully that'll sort it out.
It's probably just apps constantly eating cpu. My problem is with the laptop dock though. The battery in it gets way too hot. It's the first piece of electronics I've had that actually made me reflex my hand away from the heat.

Lets try to narrow down the Overheat issue.

Edit:
From what I have gathered from those that have provided info.
Around 120*F is normal for heavy use, around 105-110* for medium use, 100-105* for light use. This is with cell data enabled, wifi lowers temps 5-10*, also temps are for extended use scenarios. (over 10-15 min)
Heavy use= 3D game or graphically intensive 2D game, streaming videos especially HD
Medium use= basic games web surfing sites with lots of images or some flash content
Light use= sending SMS, basic fooling with settings or other basic functions, streaming music with the screen off
I think we need to get a bit more scientific about testing this overheating issue out. I need help from a large group of people. I need those who think they have overheat issues and those who do not for the info to be useful.
First off... I believe these temps are just the battery, not the CPU. I think the CPU is running relatively cool as the rest of the phone does not heat up, or it seems what heat is felt is coming from the battery only.
This would explain why people claim that the extended battery does not have this issue. As batteries with higher mAh ratings are able to handle the higher power demands with less heat.
We need to do comparison tests using the same apps across tests and the same use times as well. Also no over or under-clocking and using the same CPU governor. (and between everyone participating where possible)
I have Minecraft and Sleepy Jack, they both produce similar temps after 15 minutes of play time. (around 117-120*F) I do not know if it gets any hotter with longer use because I rarely play longer than that at a time. I am at about the same temp after only 10 minutes so maybe that is the highest it gets.
I know for certain that enabling WiFi has a big impact on the temps. My fiance's phone would only get about 95*F, (according to the SetCPU widget) but when LTE is enabled it would get to 115*F. Mine hits 105* on WiFi.
I want to do at least two tests.
Lets use the following steps to test:
-For all testing the test time will be 15 minutes of play time.
-Lets all use Minecraft since there is a free version and I know the app causes the phone to work hard.
-No over or under-clocking
-On Demand governor
Test 1) Airplane mode enabled
Test 2) 3G enabled (not everyone lives in a LTE area, if you do, data from LTE enabled would be useful as well)
Now some optional tests. I did some rudimentary testing and there seemed to be an impact on temps.
Optional 3) Using interactive governor or Lag free governor
Optional 4) Use a different kernel... If you are on stock switch to ziggy's and vice versa. (this may be the most promising test as since switching to ziggy's I have had a few lockups where the old Android logo pops up on the screen and I need to do a battery pull to fix it. This happens to the fiance's device as well)
If you do these tests, please post the results, and what ROM and kernel you are using. I will keep track of the results and update as appropriate.
Lets see if we can find some consistent data and narrow this heat issue down.
Edit:
Running Ziggy's kernel I hit 108*F kept playing and shortly after the phone did the odd crash I mentioned.
Nice, had the same idea to do one of these over the weekend - you just beat me to it
I've done alot of research/ testing heat wise, and the pseudo-scientific conclusion that i've come to is that in a room temperature environment something like 75-85F idle & 110-115F netflix is normal for this gen of phones (Rezound, Galaxy Nexus, Galaxy S II, etc) - Give or take another 5F if you're using 4G. Seems like some devices are luckier than others & stay slightly cooler, but i'd gauge that they aren't the typical use case. IMO, (along side battery) data is a huge reason we've seen some of the face melting temperatures people have been reporting.
One thing I think would really help this thread is to set an easy to follow format for posting results. For example, here's a few tests I've done:

This extended battery will get just as hot as the stock, just takes a little longer.
Edit-not quite as hot as the stock, but pretty toasty.
if it's the battery, then isn't the only parameter we need to test is current draw from the battery? no matter what radios/apps are enabled/disabled. It's bottom line is, the more we're drawing off the battery the hotter it's getting? I'd have to bring a pro in here on how Li-ion works in this form factor and why it gets hot, or what corners the battery manufacturer cut to make it possible!
The only time my battery gets hot is when I am in a weak signal area and the phone is searching for the 3G-4G signal. During daily use in a good signal area it never heats up.
My phone (and wife's also) heats up most notably during charging, especially when the battery is around 99% and going 100%. Usually the temp goes to ~ 45C (115F). In some rare cases, it was too hot to touch (dunno the exact temp). But some other times it would stay cool at all time.
Wife's first phone went into bootloop and her current phone is a new replacement. I kind of believe the overheating was the main cause of the bootloop problem.

It's more than just the battery. Also: feel free to post a test - the more data we get from everyone, the better.
One important variable missing: ambient temp.
I was just playing words with friends for ten minutes:
Ambient temp: 67, Screen brightness: 50%,
4g: ON
wifi: OFF
my temp went to 105F, it's NEVER gone to 105F when playing before... and I play it every evening. It was hooked to the USB charger at the time, and when I felt it getting so hot, I looked at battery monitor and my net charge was negative, so it was using more than it was charging off the usb...
maybe something in some of those apps triggers something that causes the temp to rise? a loop? something?

Good layout... and I think you are right about 115-120 degrees is normal for heavy use with apps that really stress the CPU or radio.

A pro huh... good thing I'm here.
Ok I'm not a "pro" as it were, but i know a thing or too.
Its not going to be simply the battery, but I think it is a big culprit, and most of these devices only provide battery temps, not CPU or internal temps, this limits our overall knowledge of what is going on internally. The battery getting hot causes the device to heat up as well so a bad battery that overheats can cause the device to overheat.
All batteries will convert some energy draw into heat. This is caused by the internal resistance of the battery. Li Ion batteries have fairly low internal resistance compared to other types, but battery design an affect power output handling. Pulling more power than the battery can handle or near its limit and you get more heat than normal. The heat to output ratio stops being proportional and becomes exponential. So that means the real kicker is the actual amp draw on the battery. How much power the battery can handle is related to both the capacity of the battery and the manufacturing process/ design of the battery construction. I bet the new devices are straining the battery more than the current design can handle. There are better battery manufacture processes for better power handling, but that increases the cost of the battery.
(BTW battery is a misnomer for these, they are cells, specifically one 3.7/8V Li Ion cell. The difference is that batteries are made up of 2 or more cells. This goes for AAA, AA, C and D cells as well. Car batteries for example are made of six 2V cells, 6V lantern batteries are made of four 1.5V cells and 9V batteries are six 1.5V cells)
This is one reason I want to do a test with airplane mode on. This helps lower the power draw and allows us to get a better overall device temp, this helps us know if there is an issue with the CPU getting excessively hot vs just the battery being stressed to hard.

I assumed most testing would be done at room temps of 68-72 degrees. If anyone tests in temps that are much higher or lower, then that would throw off the measurements.
I switched back to stock kernel, going to check for lockups and issues like I had before.

Charging always causes heat. You are forcing power into a small space.
Charging via USB should only get the battery a little warm to the touch. 95* or so at most.
Charging with AC should get it a few degrees higher. I would think over 100* is odd.
as you reach 100% is when the heat should spike to the max temps I mentioned, before that it should just be warmish.
I will check mine to see how it behaves, but all my R/C batteries behave that way.
Replacing the kernel with stock lowered my temps quite a bit. I was around 110-115 degrees after 30 minutes or so. This was with LTE enabled.
Nobody else have anything?
noticed most of my heating issues when 4g was on (even when idling on 4g). Leaving in wifi and 3g keep the stock battery cool...on the extended I never really notice the heat, even on 4g.
I realize that you're trying to keep things as similar as possible, but I had an issue today listening to the broncos game in the NFL app while charging. It got so hot it boot looped. After getting it back up and running I started monitoring battery temps and even with the screen off and just listening to the game, it would get extremely hot. Btw, I have 4G 4 bars. A couple of times I ran to the freezer and put the phone in it for a couple minutes to cool it down as the temps got above 117°F.
From here, I thought it might be the CPU, so I set the maximum setting to 384 in antutu and then let the phone sit there with the screen off just as before listening to the game and still charging. Same thing, phone got extremely hot, 115°F. Although, what I find strange, is I can watch Netflix while charging and even tho it gets warm, it never gets above 115°F and never goes into the boot loop issue. Same exact location, charger, ambient temps, signal, the works. So I'm wondering if an app is just poorly written and causes some sort of excessive use of the radio.
On another note, I had a rezound battery in my thunderbolt and never had any issues what so ever with heat.

What temperatures are you people expecting to see just out of curiousity? I mean if we run 3d intensive apps, videos, extreme web browsing we're going to see high temps since we are stressing the devices. We do have to remember these are compact devices and they are limited to what type of heatsinks/cooling they can add. From the multiple posts form this thread and others like it, we can see the majority of our devices run at same temps while under load. If it hasn't already been done maybe we should contact HTC and see what they say? Just a thought.

I am trying to find the norms and what is too hot.
I am thinking 115 is normal for heavy use. But we need to be sure, if someone says they only hit 100 under similar conditions as someone that hits 120. it may be that 120 is a problem temp and that 100 is normal. It may also be that the person only hitting 100 is just lucky.

Go play an app that is heavy in 3D, lets see what temps you get. If you go much over 120 it may be an issue.
Running Gun Bros for about 20 minutes gets me up to about 105°F. Right now after the phone had been sitting for 5ish hours doing nothing its at 98°F.

I think it is Ziggy's kernel I have never got 125f when tethering for 30min or playing GTA for 30 min. I am going to try another kernel.

Benchmarks

Hi guys, this is something that keeps me up at night. The recent software update was supposed to make performance of the Moto Z better, and in actual daily usage I find nothing to complain about, but when it comes to benchmarks it's a whole different story, I have the uk version by the way. To be frank, I used to get about 129 000 in antutu, which is pretty low to start with, and now it's down to 126 000, geekbench is lower than you would expect from this phone too, at about 1350 single core and 3810 multicore. So basically I started this thread as a place where we could share our benchmark results and discuss them, because I have a feeling I just got an unlucky unit, because it also gets real hot real fast (up to 60 degrees celcium), and I can't make it last for more that 4 hours of screen on time, and I'm really not a heavy user. I just feel strange about this phone, because I love everything else about it, and it’s good that I do, because resale value on these things is beyond awful, tried to sell it for 500 bucks for months with no success.
Benchmarks mean abso-farking-lutly nothing. If they are keeping you up any night, you have a mental issue. I suggest you see a shrink.

Well, there is no reason to be so toxic my friend, my main concern is that I may be the only one here with such a low score, and since the score got even lower after some time that could mean I may have a defective device, and that would be a real problem to keep me up at night.
I don't think there's a problem with your unit, 4 hours screen on time sounds normal without the battery mod on. That drop in benchmark score isn't very significant unless it continues to drop dramatically. I have the UK model too, and it is underclocked by default to 1.8GHz. You could try the Turbo Z kernel to improve it
Also mine gets really hot fast when using Daydream VR or anything intensive but 60 °C isn't dangerous for the SD820. (You could check battery use in settings incase something is keeping your phone awake.)
Geekbench 4:
Single core 1369
Multi core 3779
Seems benchmarks are pretty similar. I'm on rooted Android N but stock kernel so same as yours.

The only benchmark that matters is the one between your ears. And according to you, it passed.

Thank you for your comforting and friendly reply, in battery settings Android OS, Android system, and phone idle are on top when I'm not using the phone actively, I've had laughable results sometimes, like yesterday I had 30 percent battery left with only about an hour of screen on time, again no gaming involved, but this usually happens when I'm moving around, if I stay at home and nothing happens to the phone it usually won't drain battery like that. I think the reason the phone gets hot easily is obviously because of how thin it is, for example, when I keep it in the pocket it's just as hot as my body tempreture, since it just absorbs heat that easily, but has a hard time getting rid of it.

You're welcome. If you click on the graph you can see the awake time too, lately something has been keeping mine awake and draining the battery too. Not sure what it is yet, but if yours is getting really bad screen on time it could be similar. Likely an app running in the background keeping the phone awake which would heat it up more and drain the battery. There are wake lock detection apps that claim to be able to tell you which is causing this.
As you can see it's awake for long periods of time when the screen is off, and it really shouldn't be. Hope this helps :good:

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 Xiaomi Redmi Note 4 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!
I'm no gamer, but I didn't faced any heating issues so far.
Maybe I can't speak about heat as I used to use a galaxy S4 exynos (it's a portable cooker in case you don't know, easily reaching 96°c when just browsing on battery), this never heated, the temperature is about 45°c and it never felt uncomfortable hot, actually it never felt hot even in high external temperatures, I don't game on my phone, also I don't do highly demanding tasks, but I guess this phone can stand very well against whatever demanding task you want..
Ya very less heating in rn4
This phone is cool as... Hm, how to explain this.
Imagine hell.
Now imagine it has frozen.
That's the heat level of RN4. Snapdragon 625 does it job.
My phones been fine, up until this last few weeks...
Where I can't hold a charge for more than half a day... And even running phone a USB socket on the computer, the phone still discharges faster than it can charge. Battery getting hot too... I've tried looking to a culprit app that might be churning the cpu. But even process Explorer isn't showing high cpu use from any given app.
The battery app which shows what apps drain most doesn't seem to show it either.
Really worried and nearly giving up. Might do my first factory reset in the 2 years I had this phone. Maybe time to root it and install another rom, Any suggestions?

Just trying to comfort you - you are not alone!
First, it's my secondary phone and I use it only when I travel. So not sure since when that happens. Maybe since a week or so.
Now I can lose like 30% in one hour, and the phone gets really hot. I used the last 2 days. Example, this morning it had 100% after overnight charging. I went for breakfast and lost 30% in one hour (rarely use the phone when I was out).
Then I charge a little in the car, phone went went from 58% to 64%. Then for no reason battery life was normal again and by the end of today I had about 20% - and then suddenly withing 20 Minutes it went dark.
I have the phone for about 2 years, this problem is very new.
What I try right now after reading stuff on the internet, so it must be true:
Remove all updates to Google Duo (this app can't be removed) and disable the Auto-Update for it in the PlayStore. Lets see..... (it's an app I never used, had to lookup what it actually is). Did that 15 Minutes ago and phone is already much cooler.
Ok uninstalled updates to duo and blocked auto update in playstore... ill see if that helps... Thanks for the tip
I must admit though, this had made me consider getting a new phone... but I dont really want to the phones good (when its working right) does all i need i to do.... Sure newer phones are a tad flashier but not enough to make me jump to get a new one.
Wow, That appears to have worked..... I mean its not really long enough yet to tell but it does appear to have stopped the fast draining and heat... At least for the first few hours....
Thanks
So if it really is duo causing this battery drain, why do no battery analysers seem to show that?
And is it doing it to all smart phone with duo and I guess it's latest patch installed?
Has duo been spying on us? Has it been running the camera and watching us while we sat on the loo, which I'm soooooo currently not doing..........
Thanks! The recent heat issue after an update had me thinking i need a new phone. I really like this phone, its lasted me by far the longest, and best run times of all I have ever had. I was worried about fire, did a full factory reset with no installed apps, but heat was still there. I removed updates to Google Duo, and stopped any future updates as listed above, and its running cool and clean again.
Once again thanks for this post!
Yep can confirm now after a few days... no heat no fast draining... Google Duo was the culprit... is it a but that just affected mediatek cpus? Or do all android phones suffer this bug? is anyones heads rolling at google for this farce?
ITs fine and good...... no options.
While charging and playing games or using heavy data apps.... it wont get heated like expected when connected to electricity.
When on power banks it works otherwise , gets charged and increase in temperature.
One of the best thermal performance I have seen on a smartphone, thanks to the Snapdragon 625 chipset powering the phone. It had no competition back when it was launched.
Using this phone for gaming almost baked my hand

Have not experienced any heating at all
I am experiencing heating issues, I would like to know if it's just me and hopefully I just have a defective device. The battery Temp stays around 49 Celsius
My phone does get a little hot... Altho I was jus using Google duo which uses a lot of resources I believe... Not 100% if that's the case tho, and it cooled rather quickly after I ended the phone call...
I'm not experiencing any heat on the phone at all.

It gets pretty warm when I quick charge and use the phone at the same time but I think that goes for most of the phones out there
It won't get very hot. If the internal temp gets to 44C (112F) it aggressively throttles the big cluster down to about 1.2GHz, which is about half the maximum speed.
At 41C its down to 1.8GHz
At 40C its down to 2.1GHz
So in the span from 39C-43C (102F-109F) The performance drops by 50%.
A 4 degree C temperature span. This is the most aggressive throttling I've seen in any device I've owned.
I noticed this morning during charging the phone is getting too hot to touch around the upper right corner where the 360 camera attaches (which I don't have.)
no heat issues here yet.
Ya I am having some issues when I charge my phone and watch YouTube at the same time

Mine is hot at times as well. How can you tell the temperature of the battery?

Same here I feel it at times of heavy usage and charging
Accu battery says I'm around 107.4 F when I'm charging and using heavy. But that's the hottest it gets. I generally sit it next to a fan whenever I experience this. But it does nothing for internal temp which stays at 107.4 but the outside is cool to touch. And now that I think about it I may be wing about the temp. Not sure if it was 104.7 or 107.4. But that's besides the point.
Yes this phone does get hot at time of heavy gaming/ usage/ etc

I use Ampere, and put a 1x1 widget on the home screen. The widget shows the mA (+/-), battery status (charging/discharging), battery %, and battery temp.
No heat issues, not even playing Pokemon Go.
I ran my phone on battery with Waze on for 2 hours and the display turned off, made a few long phone calls along the way, the phone was very cool IMHO based on other phones I had that I would run Waze on. Only used about 25% of the battery in this 2 hour timeframe with Waze, phone calls, emails coming in and news alerts popping up occasionally. Then connect the phone to a cheap USB-C phone charger that is probably low current and drove another hour and the phone was still cool.
I have not checked temperatures, but from the handling of the phone, it clearly did not feel warm.
So far, so good IMHO.
heating issues with essential phone
having heat issues when I'm using as a hotspot for video. nothing of concern.
Never had any heat issues on 7.1 or 8.1
