Overheating - G4 Q&A, Help & Troubleshooting

Hey,
I still own and use an LG G4 as my second device, but the overheating is becoming a problem since it throttles like hell when the device overheats. Any advice / possible fix?
Thanks

What temperature is the phone getting to? you can install a cpu temperature app to check.

[Q] CPU Overheating/Prevention

Hi Guys,
I've recently got my desire back from a warranty service. The CPU was overheating causing the phone to reboot frequently, usually when browsing or playing games for a while. In the end they replaced the whole main board.
My question is has anyone had a similar experience?
I want to avoid the same thing happening again.
Are there any good widgets out there that tell the temperature of the phone?
If so what is a safe temperature?

I use system info widget, it also has some other nice features.
Actually idk what a safe temperature is for a device of this kind...i've never gone above 42° on normal use, and that was while playing asphalt oced @1384 mhz. Other than this i remember that i once forgot the phone on a radiator (lol) and it was 54° when i picked it up again, but still it didn't feel sluggish/unstable, so i must say i'm pretty impressed
Anyway people use to set the failsafe profile in setcpu @50°, so i guess anything above that can be harmful.

[Q] Optimus G question?

Hi
Hope you are all doing well. I am coming from Optimus 3D and I was moving to S3 until I saw this device. In my country it is only available used (Korean F180 versions ~300$). I have read lots of posts and reviews and I was confused due to heating issue. Firstly is this even a issue, if yes how to check if it exist in the mobile. The sellers here have Gs in factory reset condition and not allowing me to install any game or benchmark(kind of selling in as in condition) I do realize that the mobile was constantly changing brightness even when I was just scrolling and checking camera etc(unable to brighten...). Cut short what do I need to check in approx 1/2 an hour. Thanks for your time
When I first got the phone and was running stock, unrooted, I would get the "unable to brighten due to temperature" message pretty often, but it never caused any problems other than a minor annoyance. Since rooting & running custom ROMs I've always had the screen at maximum brightness, and while it does get warm after heavy use, I've never had any problems with it.

Check this out. On the Korean phone it may be different, but I bet the same menus exist somewhere.
I'm guessing that since you live outside of America that you have the E975 model. The screen dimming and processor throttling is done to avoid overheating. You can disable it without any problems.Go to the dialer and enter 3845#*975# . It will take you to the hidden menu. Scroll all the way down to "Thermal Daemon Mitigation Off". It should be set to off by default. Switch it to on. This will stop the processor throttling and screen dimming.
thanks guys I bought it
If u set ur kernel tweaks on trickster mod then u will never get any over heating... Maybe a little warm but not overheat. When I first bought this phone I was experiencing bad overheating and that was every time I use the phone. Then I downloaded trickster mod and set the I/o scheduler and gov etc... And I never experienced overheating and my battery life went threw the roof!! And custom kernels help a lot as well.

Overheating like crazy!

Hey guys,
My nexus 7 is not behaving normally anymore! It is overheating like crazy! Even by just browsing facebook the device gets a cpu temp of over 70°C and it even got up to 105°C once and then it rebooted, now this also means that I can't do anything with the device: it will not charge because of high temperature, most apps force close too!
I also did a antutu benchmark recently and the cpu scored a mere 500!
what is wrong with this thing?
Can anyone help me?
Thanks,
Noahvt

Maybe there's some process that's running in the background that's over taxing the CPU? Have you checked to see if that's the case? Have you tried booting into safe mode to see if the problem goes away? What steps have you taken to try and troubleshoot?

CPU Temp is over 65-70C plz help

my phone have several issues but this heating problem worries me the most..
when im not touching the phone (placed on the table with display on but on lock screen) it is 35C to 38C
when i take it in hand nd unlock and even if i do nothing it rises and reaches 42-45C
when i use apps like gmail, maps, or sms the temprature is around 45-48C
when i play small games it goes between 50-60C
but the most worrying part is when i play heavy games.. the temprature goes above 60C and stabilizes at 65C.. aont once in a while it reaches 68C but comes down sooner
when i run benchmarking apps. the temprature went 70C and even reached 72C twice... will the device can handle such temprtures?
i know most of the processors are made to handle not more than 70C.. so im doubting this heat might burn my phone internals..
is it like this for all snapdragon 615 phones? or will it b fixed if they update to lollipop which is best suited for 64 bit processors?
or should i return the phone ( i have 6 days ) coz its defective??
please give me a reasonable reply some1.. i tried all forums and no reply.. please help me... i dont wanna regret buying this phone in the mean time i dont wanna regret returning this phone either so kindly help me
Please check the battery stat, and see which one is using more, I think You have mediaserver issue, If mediaserver is the highest (above 30%)
then find a fix for it, It is a bug in kitkat

already went through it.. no media server issue for me... its due to some other issue i think..
im getting same issue but my load temperature is around 55-60.
i emailed it to yu customer care.they say its normal to heatup during games and internet bwosing :/

But still 55-60 during asphalt is quite high

Hi Kartik00 ,
Did your issue got fixed? Heating problem got solved ?
It is not a problem!
​It is actually OK. Most of the phones give battery temperature as CPU temperature as they do not have a heat sensor integrated with the CPU.
But for yureka it is different. I mean yureka is special one. It has a heat sensor integrated with CPU. CPU can heat up to 90°c that is normal. But when battery starts to heat up, there is a issue there. Our yureka is fine. :good:
Download CPUz it will give you a pure idea of this

yh thats right.. i realized it after asking around abt other ppl who owns 8core phones its not even a ISSUE.. also after cm12 update my phone doesnt heat much.. hot pluging isnt effective yet though but 2cores (from the performance cores not the power save ones) does goes to sleep when we set it to powersave mode
rollback the update to stock ROM (4.4)
Lollipop is awesome.BT the heating issue is still tr.The CPU governor s are not adjustable in lollipop. BT in kitkat we can adjust it.
In lollipop the CPU always at 950hz (min).so it heats more.

I guess its not just software issue but also a design flaw made by CoolPad. They cover the main processor chip and eMMC chip with aluminum cover. I know this cover is used to prevent dust to get in and static electricity, but it also cause heating problem. Moreover, they place the LCD on top of it. So if you want to get rid the heating problem, don't buy YU, but buy MI 4i instead. If you don't use the phone, the phone temperature will stay at 45-50 degree.
U r suggesting different phone as a solution? & that too atleast 4k costlier one

How to avoid boot loop problem ?

Hello
Lots of G4 devices gets boot loop in time.
warranty fixes it free for now. but even new 1.1 v hardware versions gets bootloop (according to reddit pages)
I think there is no safe device. So how can i avoid this problem ?
According to people this problem caused by overheating, that makes solder weak. then some cpu core connections gets loose and causes boot loop.
My desperate solution is lowerclocking the device. I'm using cpu tuner for disabling 4 cores.
I tested this with benchmarks and games. It seems not overheating.
But cpu performance only 1/3 and there is tiny lags in every app.
If you have better solution, let us now. You are the only hope !
i really like this device and i dont want to buy some mid level f 2.0 camera devices.
excuse my english

I think flashing a custom kernel and underclock A57 cores (the bigs). This could prevent overheating, losing very little performance.
in the next few days I receive my phone, i will do that and test what happen. I think that could be a good solution to avoid a bootloop issue.

are you under warranty.? if yes keep using it like always if you try to prevent from happening and dont bother running it then disable the cores..
