CPU throttle - LG V20 Questions & Answers

Is anyone else having issues where they're phone locks at 600mhz and is laggy as hell?I've tried multiple Roms even stock and get the same situation..It seems that if I try to charge my phone at all this gets triggered.

apparently charging and quick charging throttles it I believe...quick charging even worse. that's pretty hot for a battery temp so yeah probably throttles.

I get the same problem even it is not charging. When battery temperature approach 40 degree,sometimes 38. The cpu scaling is locked and capped below 652MHz and become so slow to use!! It happen indoor and outdoor, so annoying

Phone gets really hot when charging... over 100 degrees Farenheit

Im plugged into my comp via usb to my phone and strangely once it starts charging...my phone's temp soar! Is this typical? Im seeing the temperature marks via SetCPU
Thanks in Advance
mine also gets hotter but I don't know whether it's as hot as yours, but I think a bit increasing is fine.
The higher CPU speed may be the culprit, this happened to me before. I changed my CPU speed back to normal while charging and it doesn't get hot.

I tried underclock my CPU speeds down to about 245 mhz and the temps still appear to be quite high at about 98-99 Fahrenheit? Ive also got my brightness down to the lowest setting and always Taskkiller Apps beforehand. Anyone know why the temps are still up there?
Mine gets brutally hot (45 degrees celcius) which is about the same when im charging over usb on my ps3, are you using it when its charging? also maybe your usb port isnt giving a constantly equal charge.
Odd mine is set to 358/245 for charging and of I'm not using it my temps don't go over the ambient air temp.
If I am using it my fail safe kicks in and never gets over 41c..

Hmmm...its seems like the usb port is fine
im not sure...i think its the phone's battery maybe? Becuz sometimes even when not charged...the temps are still pretty high....
Lets say ive been playing a game on an app for about 30minutes on medium brightness...I could actually feel the phone warming up
Another scenario I think could be the cause is actually my ROM maybe? Cannon's Complete Eclair has my cpu overclocked at 576mhz which isnt a whole lot any means.... but maybe it has to with the kernels and system related modifications?
Idk...im just trying to throw things out there
Anyways thanks in advance

[Q] Nexus 4 heat problem

I am getting bothered by the heat of my nexus 4 especially at the camera side..., when I play psx emulator it really gets hot and it gets hotter when it is charging... even if i am only watching or streaming the internet it gets noticeably hot, so i would like to know if this is ok or not.
what are apps that could monitor the temperature?
what is the normal temperature when gaming and idle?
I would like to know about this things so that if my unit is a lemon, i could return it to lg for the warranty.
thanks in advance.

you have a quad core device, its normal. when you stress the cpu, gaming, streaming, itll heat up. when you charge, your battery will heat up. the back o the phone is glass, so itll feel like it gets hot fast. when the device hits a certain cpu temperature, heat throttling kicks in. this will lower your cpu speed and cool down your device. when it goes over the cpu safety temperature(100C i believe), the cpu will shut down and the phone will power off. there are several apps that show the cpu and battery temperature. remember, battery temperature and cpu temperature are two completely different temperature readings.
System tuner gives you cpu temp. But you should get an app that tells you battery temp as well...

simms22 is right you can under clock it safely kernel tuner is free on play
Intel CPUs (i5, i7, etc.) can survive going over 100 degree Celsius, but the commonly quoted safe temperature limit for long term operation is 70 degree Celsius. I would assume that the same holds true for other silicon chips, and find it difficult to believe that the shut off temperature for the Nexus 4 is 100 degree Celsius - you will be getting serious burns on your fingers by then.
Wait..., I recently played a 3d game and my temperature is reaching
CPU: 67c
Battery: 50c
Is my phone a lemon or its a normal case scenario?
Hi all,
For "hardcore user" there is a thread with a solution to limit the heating :

That is a little worrying. Are you using a case? Also what is the room temperature where you were using the phone?

sorry for the late reply I thought no ones going to reply with my post, the room temperature is 31c. and I dont use a case

Throttling?

Any one else had an issue where the CPU locks at 600 MHz while charging?it literally makes my phone unusable from the lag..

I don't have any numbers regarding CPU speeds, but, throttling while charging is common.
If not for it, the phone would likely get too hot.
are you fast charging? that could be why. I've never had this issue, but I've only fast charged it once, and I wasn't using it when I did. my phone NEVER gets hot, especially when using camera for a while, but having it on fast charger for 15 minutes it got really warm, so it wouldn't surprise me if fast charging throttles it.

Lg V20 Aggressive Thermal / CPU Throttling?

Phone: VS995 Rooted running WETA rom + Werewolf Kernel.
Issue: Phone heavy CPU throttling when charging, gaming or even just booting. The CPU throttles to 652mhz on the small cluster and 1036mhz on the big cluster whenever I do something cpu intensive for a couple minutes. Obviously this causes a lot of stuttering and lag. I have to let it sit untouched and it will go back to normal.
I've monitored the temps and CPU doesn't go above 50c when playing games and my battery temp is below 25c. Even if the cpu temps go back down to 35c, it takes a while for the frequencies to ramp back up to max.
I'm using EX kernal manager and have disabled core_control and msm_thermal but doesn't help.
I've tried the stock WETA kernel and Werewolf kernel but they both don't seem to affect the heavy throttling at all.
Wondering if there is a kernel or a fix for this, kinda like the lg g3 thermal mitigation setting, or the CTTMOD found on other devices? Or maybe my device needs to replace thermal paste?
Thanks!

I've noticed this as well on WETA but only when charging. For some reason on WETA on stock kernel this phone slows down dramatically when plugged in. I just thought it was LGs method of thermal control but on MEGAROM V4 it doesn't slow down at all for me when plugged in so idk but would like to know how to fix cause I have it plugged in during driving a lot and switching back and forth between music and navigation becomes frustrating because of how laggy it gets

Yes! That's exactly what I'm experiencing too.
Having it plugged in throttles the cpu immediately. Doesn't matter if it's a quick charger or a slow charger. The battery and CPU temps are both low so that's not an issue. Even when it reaches 100% battery and just trickle charging, it still throttles randomly.
I'll start a different rom and see if it helps.

Yeah I recommend MEGAROM V4 although I'm on the T-Mobile H918 variant and not sure if there are any discrepancies to be accounted for but give it a shot and see
Having the same issue
My phone always stay Cool even when charging but cpu frequencies keep changing.
Even when i set the cpu max to 2105mhz it automatically slow down to 1036mhz , which makes the device super laggy and shuttering.
I've tried stock rom,weta,and some other roms and also tried some kernels nothing seems to be fixing the issue but Resurrection remix rom fixed it, no frequencies changing no lag no shuttering but i also has a problem that second screen doesn't work at all :/
yep same issues stock here.. just made a topic and realized you made this lol. stock rooted fwiw. I can't stand it. this phone has become such a lag fest that the galaxy s6 I was given for work seems faster, and that's two years old.

I think I found a fix!
Here's a link to my thread: https://forum.xda-developers.com/v20/themes/mod-fix-cpu-throttling-charging-gaming-t3650705

Radom performance

Hello everyone,
Always i have searched all internet before writing this post.
My LG G6 H870 have strange behaviour.
Actually i am using open oreo v20g installed by TWRP . I have magisk and mk2000 kernel, but tried also Beast , and Marshall. I tried also back to stock with KDZ file.
Problem is that after running CPU Throttling app i can see temperatures and frequency.
After boot it shows sometimes that frequency go to max 2,35 GHz on 2 cores, and 2,18 GHz on other 2. Temperature is 35*C per core. Performance shows at start over 100 GIPS and is going down to 70-80 GIPS.
One moment later, or after Next reboot after running test, cpu frequency go to MAX 1,05 GHz on all cores even temperature is 23*C on cores. It shows 50 GIPS and.
Dry performance test is not problem, but i feeleing a low performance at systemy interface and web browser - its laggy.
Antutu shows below 100 000 points.
I tried kernel adiutor to set frequency, but on any kernel its not possible,becouse if i set frequency itd changes itself after while to random frequency.
Tried to change governor for example Performance, but frequencies never go over 1,3-1,4 GHZ.
Temperatures never go over 40 at idle. Phone body is not.
Do You have any ideas where is the problem and what can i do? Frewuencies are totally random at stress or higher usage of cpu.
Thank You very much
Here's screen shot of test. Straight Green Line is frequency 1,05GHz at testing
I did a full back to stock with LG UP and Uppercut with v20a KDZ firmware. I locked bootloader by Tool all in one, By OTA firmware updated to v20g. Problem gone, everytime i can See over 100 GIPS in test and device seems to work like a charm.
Thanks

Wait so what was the issue. Was it the kernel??

It's looks like the problem is with hardware. On stock V20g, and now also on V20h problem still persist. It's totally random. Now i am on locked bootloader, stock kernel and sometimes frequencies locks at 1,05 GHz even if temperature of cores at test start are between 25-30*C on with CPU Throttling test app. Phone still lags sometimes.

You know i noticed something like that too, sometimes the phone runs fine but sometimes I'd be doing some really simple activity and it just heats up and lags and also ram is getting eaten on the stock ROM.

On stock i disabled many stock and system apps with LG Package disabler, and phone never gets Hot. Only when testing or doing heavy tasks. Ram is also normal. I recommend disable bloatware and unused not critical apps.
My problem is that phone can't be even warm when heavy apps are computing.
I didn't found a solution, but i noticed, that is it linked with charger.
When battery is below 50%, cpu clock very fast jumping from 1,05 to 2,34 GHz and then the performance is near 60 GIPS. After connecting charger CPU frequency is stable at 2,34 GHz and throttle is lowering frequency to 1,05 GHz and stay at this frequence even a temperature is low after while. After disconneting charger, frequency is going higher and higher. I attached screenshot when is it visible.
When battery is over 50%, cpu frequency is stable at 2,34 GHz, performance is near 100 GIPS and is lowering with throttle, but when i connect charger, frequencies are unstable and performance falls to 60 GIPS.
In summary, there wasn't problem with kernel, or software. I think there is problem with hardware, but i don't know how to diagnose problem.

Yea it's probably your hardware try underclocking the voltage or smthn like that

Thanks for help, but under or overclocking not working. Tried to change clock by max 50mV but without success. I tested more today and problem starts below 70% battery level. It's about 3,8V of battery.
I also tried disable cores. After disabling 1 of 4 cores (no matter which one) clock were jumping from high to low. After disabling 2 of 4 the problem dissapears and clocks are high as it should be, but only on 2 cores. It looks like phone don't have enough power to deliver energy to high intensity SoC usage. I'm going to try dissassemble and assemple motherboard and battery again, maybe connector is not fit good, after sim tray repair.

I don't advise that but go ahead and does this happen on every ROM or no
Any update? My phone does the same. Is this problem battery or thermal related?
