LG G3 getting very hot even despite heavy CPU/GPU throttling - G3 Q&A, Help & Troubleshooting

Hey guys!
If searched a lot for a threat regarding this problem, but I only found general overheating issue threads. So please don't be too harsh on me for opening a new one.
I have the LG G3 D855 (16 GB with 2 GB RAM). I'm on Fulmics 5.0, but it's basically on every ROM I've tried since Lollipop.
My G3 gets very hot (up to 75 C° or 167 F°) when I play games, even with "simple" ones like Crossy Road or Clash Royale. Yes, it warms up when I use Chrome or other apps, but never that much, it just gets a little warm. But games really make a small oven out of my G3. Funny thing is, I have Xposed installed and use the module "Performance profile" to throttle the CPU to about 1200 MHz and GPU to 300 MHz in games. It still gets hot, as if I havent changed anything. But I can see the toast notification that the profile kicks in as soon as I start the games.
I've already swapped out the battery (for a new, original LG one and a 6000 mAh extended battery - problem persists). I have Greenify installed and use it for Facebook etc. I have frozen all unneccessary apps like LG Health. I've (clean) flashed different ROMs, I've tried different kernels, it gets maybe a little bit better, but the problem still persists. I changed my DPI from 640 to 550 if that is of any interest.
Other than that, my G3 works like a charm!
Maybe you guys have any advice

[Q]Some questions about kernel

Hi, i've got some questions about e975.
1. I an looking for a kernel with oc option.
2. And would be good if this one or anything could minimize throttling issue. If not, i would only want to know how to fix throttling.
3. How big is the difference beetween 4.2 and 4.3 roms in performance.
4. Is 4.3 roms drains battery faster?
5. Does 4.3 roms has an effect on throttling and overheating?

1. Why do you need oc ?i said it many times,doing oc on this cpu is like adding 10 bhp to a 600bhp engine. The improvements are almost 0. If you want to score big in tests,you are in the wrong forum.
2. No throttle or overheating. Besides,if you want oc,won't that be another heating source?so,you must make up your mind.what do you really want?oc or a cool cpu?
3. If you mean by performance benchmark results,again,you are in the wrong forum.
4. Depends. You do realise both 4.2 and 4.3 are UNOFFICIAL builds,so the drain,compared to stock is a litle higher. This is also relative to every phone/user. If you have 2-3 email accounts,with push notifications,use 3g/4g connection 24/7 on a weak signal area,gps on,autosync on,not to mention what apps/services are runing in the background....well...buy yourself a mini nuclear plant.you will need it.again,non-sense question. We don't know how you use your phone...
5. Don't know what phone you have,but,at least on mine and my friends phone,throttle and overheat are urban myths. Amd most of us are power users,not newbies regarding smartphones. The phone behaves as it should,even on stock.no abnormal,paranormal activity with the cpu,as we constantly monitor it. Same with heating. The g is one cool device.

* 1.You're right, there's no serious reason to oc Optimus G, i had an old routing from single core snapdragons (there overclocking from 1ghz to 1,4ghz gave an pretty big effect in apps).
* 2.Ok, if my phone will have 1,5 ghz if there will be a necessity (gaming) i don't have to oc it. (My problem is that I am poweruser too (i have e975 not so long) and i have a cm 10.1 based rom, but i still have overheating and throttling issues, (that is cpu slows down to 1,1ghz so i've got non-smooth gaming). After about 15 minutes G gets insanely hot. I heard about the same problem in Nexus 4, but in that case there were sth like a patch, which reduces heating effect.
* 3.I mean performance in demanding games (like Asphalt 8 etc.)
* 5.I've got a E-975 (European Version of Optimus G).
1 have the e975 since march. never encountered the slightest issue in games. and i play alot of games(rr3,asphalt series,modern combat series,nova series,shadowgun,galaxy on fire,you name it). you do realise G is top hardware,right?And the asphalt series is not so demanding. It's working fluid on my gf's arc s.
about the throttle,if you are a power user,you know this is a rare thing, and it happens if you make a dirty flash. when you do the things by the book, the phone flies. same with the heating. my old s2 was hotter than the g when i play games.again, measured with proffesional tool, not by hand.sometimes the s2 was over 57 degrees.with e975, after playing modern combat 4 for about 40 minutes, it never got over 50. not to mention i'm using a silicon case.

I never do dirty flash, I always do a full wipe (because i flash a new version of rom when the changes are major).
LOL, so you said that asphalt series are not so demanding? Asphalt 8 Airborne: doesn't even work perfectly fluid even on Medium quality, on High i have very unstable framerate (12-28 fps). I thought that temp nearly 48 Celsius degrees is very high, I afraid that my screen will broke because of temperature.
Is your Optimus G is underclocked to 1,1 ghz? If not , does it works always on 1,5ghz when it's necesary?
EDIT:
Whoa! I've flashed 4.3 rom (Mokee OS), and now Asphalt 8 works fluid on high,no framerate decreasing, i was playing for 10 minutes and phone isn't so hot. It's on a kernel attached to rom.
Guys, the G has cpu temperature sensor? Sell mine and forget to look at it. You can check with android Tuner, on cpu tab. Pay attention, I'm not talking about battery temperature.

Questioning Performance on my Stock G pad (Games)

I'll preface by saying I bought a LG G2 Phone and I love how everything works on stock. Pages load quick, no noticeable lag, games run great with no slowdowns.
When I heard about the G pad, it was a no brainer for me, snapdragon 600 processor sounds like the only difference other than the camera which i don't care about, I should expect similar performance. Seems I was wrong.
The only thing that stops me from loving this tablet is the speed. Experiencing some stutters while web browsing while my G2 experiences none both using chrome.
The biggest thing that bothers me is my Go to games for the Gpad. Kingdom Rush and Kingdom Rush Frontiers. This game plays at 70% fps roughly and constantly dips down to 40-50% fps, so annoying and cannot see past this. Runs without the smallest slowdown on my G2. Only thing different between these devices is snapdragon 600 vs 800. This isnt even a demanding game shouldn't they play well on both. I have 1.3gb of ram free so thats not a problem.
Should these 2 devices not handle non demanding apps/tasks similarly? ( Lg Gpad vs LG G2 ) They have very similar hardware and run off the same LG version of android. Is there a chance I have a bad tablet?
Is this a widespread issue?
What do you mean by 70% fps? How did you even measure that? I also play Kingdom Rush Frontiers but haven't noticed any lag or drop in frame rate. The scrolling in that game is weird and is a bit laggy though when scrolling the map.

If you're using a softkey hider I highly recommend that you temporarily disable them when playing a game and that you don't have any big memory hogs in the background on.
Let it cool of a bit if you have used it for a long while before or if you have been playing for a larger amount of time.
Lastlyif you are on stock rom as in realy stock from the retailer then I highly recommend that you root it and install either Malladus(which I am using) or another AOSP rom. The stock rom has some serious issues with smoothness and LG really dropped the ball on that.

Help with my Xperia ZL, got me really mad !! :(

Hi guys i just got an Xperia ZL C6502 months ago and its a big headache im telling you the cellphone is great but whats really happening
The problem is that in heavy use the Snapdragon S Pro 600 Quad to 1.5ghz comes over 65°c or 149°F wich is absolute damn high so what? it drains the battery from 100% to 0% in around 2 or 3 hours and the cellphone is hot as hell, and not only in games, using apps like Whatsapp, Facebook, etc too.
When im not using it it drains normal ammount of battery like 2 or 3% per hour but when i use it a little while at least it drains 10% of it and im like charging it 2 or 3 times per day.
It has the lastest version of Android supported by it wich is 5.1.1 and rooted by Kingroot App i thougth that rooting it i was able to change the CPU frequencys but here comes the problem, i tried a lot of apps and no one seems to result, my intention was to clock it to 384 thath it seems to be the minimum it tolerates and 809 to maximum to reduce the battery consumption and the CPU heat but when i clock it or push the "apply this settings at startup" the clocks are set to 1512mhz minimum and maximum.
My question is, why this is happening and if there is a solution to my problem.
Sorry for my bad english im spanish and thanks by the way
Anyone?
Hello, first of all the right processor of this device is the Snapdrangon s4 pro (APQ8064).
Related to your problem I think you could try installing another CPU control app, there is one I've used before and is on the playstore "No-frills CPU control". Install it and change the CPU governor to "conservative" or try others... Hope this is helpful for you.
PD: I'm Mexican and speak Spanish also, send me a Personal Message if you want, I think I could help you

LG G4 818p heats like hell and batery drayn

Hello all.
I was thinking if anyone here had a problem like mine or knows what to do.
I bought a LG G4 dual sim 818p last week.
the phone is great, but it has some problem that i think is software related, and i think is governor problem.
It has the latest android version avaible, original from lg.
the thing is that in standby it is great, i get 1% drain in 24 hours...
but if i use the phone just for web browsing or facebook it heats as hell, and i lose 1% batery in 3 minutes...
no gaming, no downloading and no SIM card in it.
Just drains as hell and gets to hot just for web browsing.
I also noticed with battery gsam analyser that if i use the phone it always puts the all processors on 100% speed and for me that is the problem and it has got to be a bug on the governor settings.
any ideas?
many thanks,
what can i do?

Not having a simcard does phone scans fro network?
you could do factory reset if same flash stock firmware using LGUP.. if its marshmallow then be careful wich antirollback you 0n... also i read
LP has better battery than MM.
Hi,
many tanks for your reply.
I also did the same test with the sim cards inserted and the problem was the same.
Meanwhile I flashed the original rom version V20b (I had the V20f) and althou the problem is not gone, things have improved mery much.
I am now sure the problem is software related with the rom and the way it manages the cpu load and speed.
I am pretty much sure if developers of the original rom had more attention to cpu load vs cpu speed this phone could be awsome and have great battery life.
The thing is way does it need to have 6 cores running on full speed just for webbrowsing? It seems to me they dont know how to control the ammount of cpu cores and speed vs the load we put on it.
regards,

You can install V10 Lollipop and heatup problem will be resolved. MM has issues on 818 in terms of battery drain + heatup.
Even I am currently facing Battery drain Issues was thinking to switch to LP...!! But my LGUP does not detect my phone !!! (818N)
from my experience, i've already tried rolling back to a lot of different version of lollipop, v10k rooted+debloated, v10l rooted+debloated, camuix v3 (v10d base), camuix alpha test4 (v10e base), i love using xposed framework, and also i'm a user who loves installing things,it was about 400+ apps/games installed and guess what, it drains my battery 5-7% every 15 minutes without doing anything. and then i tried again using marsmallow, first, i install v20e, but i don't like the UI that much, so i flashed genisys system.img (v20c base) via download mode and disabling some bloatware via debloater. so after having v20c with genisys ui, i install every apps/games i had before 1 by 1, and now, there's about 428-433 apps/games on my phone. after day to day use, i don't really feel too much battery drain regarding a lot of apps/games i had. and also it will go overheat just when playing games or watching videos, it doesn't really overheat when browsing. and about the SOT, it can go up to 3-4 hours depending on network or gps uses, when i use my phone as turn by turn navigation, it can survive about 2.40-3.20 hours. actually, i do really miss every xposed framework i uses before, but i don't really feel so much different. because now in marsmallow, i can use my 128gb microsd as adoptable storage, a lot of CPU & GPU governor improvements, a lot of OOT improvements, a genisys theme, and by using such apps like floatify, fooview, appblock, and adguard, it just feel's like a rooted phone. and one last thing, now i can throw away any kernel or script modifier i've previously used, it was a really really hard time on optimizing this phone with that method, lolz. btw if u need some screenshot, i'll post it

well if you unlocked bootloader flahsing other kernels might have different governors some are foe performance some are more tame... yes i agree why use alot of cores when it can handle with one core or 2.. but thats how governors are some are in ondemand it goes from lowest cpu to highest cpu only if you open a pic.. its less lags but all that cores arent need it.. a governor like smartass v2 or intellimn will use less cores depending on what you are doing.

LG G4 CPU overheating?

Hi! Sorry if this is not the right place to post this, But i cant find anywheres else to post a forum post about this problem. I've looked it up on google and everything, And i just can't find anything.
My main question is what is the safe temp for your LG G4 cpu?
My cpu runs around 30-35c on idle, I do have instagram and messenger, snapchat, and a few other games running so that would make sense.
When playing games on my phone i do reach up to around 40-45c max, I've never seen it go up past 45, It seemed to do quite well around then. The game didint lag and the phone was still snappy.
Is 40-45c safe for it? I dont have a case on it, I just bought it today and already had my lg g3 break on me because of overheating, It destoryed the cpu connections and so. Ya. Do i have to worry about my lg g4 doing the same? Battery temps are all okay, Not worried about them. Just cpu!
Thanks!
45 degrees is too low for multitasking. So it is normal, you don't have to worry about it
