[Tutorial] [V20x] Disable / Adjust Thermal Protection for Slow AC Charge & Tegra 3
Part 1 - Disabling Thermal Protect during Charging that will result in Slow Charge (USB Current) issue on AC supply
Our LG 4X has an in built function to restrict heat build-up during AC charge, when the phone is already warm after intensive use.
Unrestricted heat build-up will potentially result in damaging chips.
But sometimes even when the use isn't highly intensive under cool envoirment factor the current is still restricted by this somewhat over-sensitive and unadjustable feature. Consequentially when user is using the phone for long duration apps (ie watching movie) while phone is under AC outlet charge battery will still run out, albeit at a slower pace.
Below is the steps to disable this function:
Dial 3845#*880# to enter hidden menu (do not press the green dial button!)
Navigate to 'Module Test'
Navigate to 'Charging Test'
Tick 'Unlimited temperature charging'
Exit Hidden Menu
Charge using AC outlet
If charging cable was already plugged in and in USB current, disconnect and reconnect to see result
Only works on V20x Jellybean ROMs.
Phone restart will return this function to its normal state.
Part 2 - Disable / adjust Tegra auto throttling for thermal protection that will result in game lags during high chip temperature
Besides protecting our devices by controlling heat from charging current, 4x HD also has an inbuilt mechanism to restrict overheating of the chip during intense 3D gaming or graphic heavy applications.
When the heat is detected to have reached a certain level, this mechanism automatically scales down the CPU to prevent anymore excessive heat from being produce. However, scaling down the CPU will also produce significant lag for the user application.
To adjust this function, user will have to follow the guide below:
To adjust this function, user will have to follow the guide below:
Device Requirement: Root, Root capable file browser
Navigate to directory /d/tegra_thermal
Open-for-edit temp_throttle. Set to user preference, typically above 65000
Save
Do the same for temp_throttle_skin
Save
You are now good to go
Settings will revert after phone reboot.

i like to take screenshot that it works but how do i take screenshot of heat? lol?
This should show that my phone doesn't switch to USB current when the heat is high
Red = Temperature
White = Percentage
Green = Voltage
Botton yellow bar = charge status
White bar = display on

So thanks for this hint, and bacon joke After all this is MultiPurpose device
is it possible to just increase the temperature ? i think the temperatur protection is very low . Because on v10h never had this prob...
V20B has significantly increased thermal protection activation temperature. To less aggressive user its presense now will hardly be felt.
updated for official V20 release
Do you guys think there's any way to set this, or the changes this implements (it must be changing something, probably in files), into a script or something that could be executed at will (or maybe even through a tool like Tasker)?

on theory there's a file somewhere, but where is it?
The files for that are named temp_shutdown, temp_throttle and temp_throttle_skin found in /d/tegra_thermal, u can change the values, but next boot overrides. Someone could make a script for Script-Manager, which run after boot and set the values new, or sets high and low via widgets (Script-Manager can create widgts I think)...
U have to change the values to about 71000 or more, shutdown should be left as 90000 (setttings in V20a)

I thought we talk about both, disable thermal protection of charging (done via hidden menu) and disable thermal protection (down throttling) on overheating, ur right, thats for more cpu power / less throttling...

ah right, sorry i didn't catch that.
i can add this topic to first post. thanks
updated first post in tegra thermal protection.
i tested
I tested this no change at all as far as cpu mhz cpu still throttles to 1000mhz to one core when playing anything even the gba emulator it starts fine dual core 1400mhz then when it throttles to 10000mhz one core it lags madly after playing for 5 minutes i thought this would work.
edited thermal-throttle to 80000 i assume 80c
thermal skin to 55000 maybe 55c for outer layer of the phone so your skin won't burn.

As i am frustrated with this issue ( brightness falls to 87% and then to 70% after a 10 minutes video playback ) and i am not rooted can you guys confirm that the trick ( Part2) works ?
I ask this because i didn't want to root my phone and this procedure demands root.

for the tegra thermal adjustment you have to be rooted.
btw there's no other phone with easier and safer root method than 4x. and androids are meant to be rooted

I rooted my phone, edited and saved the 2 files at 85000 each.During the procedure my temperature had already dropped to 87% due to high temperature and couldn't go up after the edit of the 2 files.Then i waited for phone to get colder and then i watched a 20 minutes youtube video on full screen and with 100% brightness.The brightness didn't fall !!!!
Thanks a lot for the guide !!!
I have noticed the Xiaomi Mix has some persistent software thermal throttling after a short period of time.
I ran the same test on a OnePlus 3T and noticed this throttling issue is not present.
It's possible the temps to start throttling are too low on the Mix.
Is there any way to modify or increase these throttle limits?
I know this has been done before but I cannot load the Thermal conf file in /system/ etc / thermal-engine.conf
Can we replace the file with something else ?
The OnePlus forum members released several versions of the file with different throttling temps. Can we use these files or make our own.
https://forums.oneplus.net/threads/oneplus2-how-to-fix-thermal-throttling.417108/
Did you ever get any further with this? My phone idles at ~35C. I read a review that said throttling begins at ~40C so I get throttled when I do virtually anything.
I've only had this thing 2 days and the performance has been worse than my old Nexus 6 because the cores keep getting capped very low. I was copying some backed up files over WiFi from my PC. It was lots of small files so it was running for 20 mins or so. When I was trying to do other stuff in the meantime it started to get really sluggish. I used to do exactly the same thing on my N6 and I could never tell that file copying was running in the background. I checked Kernel Auditor and it was showing temps ~50C and the cores were all being capped around 5-600MHz.
I've tried the stock ROM (stable and beta) and EPIC, and Lineage/RR. It seems to be a bit worse on the latter two (Antutu won't go above 100k, but it's like 140k on the MIUI ones) for some reason, but it's an issue on all of them.

I have absolutely gotten further here I have managed to get throttling completely disabled actually.
The highest temp the CPU got to was 42 degrees Celsius after running Dolphin for 2 hours straight.
There is no need for thermal throttling on this device at all, hardware does a good enough job clearing the heat.
To stop the thermal throttling you need root access.
Use ES File Explorer from the play store and enable root access
Navigate to root and look for Folder system/etc and find file called thermal*******.*** ( I don't remember what it's called )
Cut this file from this location and paste it into another directory. I moved it to the sdcard for easy access. This way you can move it back if you do not like the results.
I have not experienced any overheating with this, also the battery doesn't drain like crazy. Performance is greatly improved with speed matching the Snapdragon 835 in a few scenarios.
Oh yeah restart the phone after you move the file so it can register the changes. Clock the cores appropriately with Kernal Auditor to make sure it can run at full blast when it needs to. On demand is way faster than interactive.
Cheers. I actually read the links you posted and renamed the conf file. After a reboot it was flying. The problem isn't so much the throttling, it's that mine idles at ~35C already, so it was getting capped when I did virtually anything. If I run Antutu 2-3 times in a row and check the temps in Kernel Auditor it can be in the low 60s. Using other temp apps (CPUTemp) it only shows about 45C tops.
It definitely does feel pretty damn warm since I don't use a case. but I'd love to know what the 'real' temp was. I tend to believe the lower one since I got the 45C warning when using EPIC and that's exactly what the app said. it was.
My Antutu scores increased substantially too. I was sometimes dipping down to 80-90k but I regularly get ~140k now, even 160k once. I know not to go by those scores but when I could never even get above 100k it was a concern.

Yeah I'm thinking Xiaomi severely limits the thermal threshold to improve battery performance.
It's kinda all they care about in Japan for some reason.
Makes for some great performance improvements without the thermal settings being active.
This setting change is almost necessary of you need some heavy work done.
Glad you were able to get this changed.

I think our best solution would be a modified .conf file that increases the thermal threshold as opposed to completely removing it.
Until this solution is available then this is our only choice.
i agree... i think with a ROM kitchen mayve this fil can be readable... anyway @ this point, we can only hope somebody dectypt this file to support various cool modification available over XDA...
Edit /
it seems HTC make same stuff... here it is a guideline ot example...

I had the same issue. I was getting 165k+ in Antutu but the phone would get uncomfortably warm when doing multiple passes, or gaming for extended periods.
In the Thermal section of Kernel Auditor, I enabled the Core Control and Temperature Throttle options and the phone still gets warm, but only as warm as you'd expect. I still get ~155k in Antutu consistently and the performance in general is still very smooth. I have the CPU governor set to ondemand, and the GPU governor to simple_ondemand. All other KA settings are default.
One other thing I always do is to reduce the Window Animation, Transition Animation and Animator duration scales to .5x (1x by default). It just makes the phone feel snappier in general. Settings > Additional settings > Developer options (MIUI-based).
I'm using the latest EPIC ROM. Using RR/LOS I couldn't replicate the same high Antutu scores consistently for some reason. I quite like MIUI after years of using CM and CM-like ROMS anyway.
already reduce animation x0.5... MIUI use a lot of this animation with complex and (very long calcul) then reduce this number make device seems much faster... anyway, u right...
A custom kernel for miui base... based on Dragon XIA exist in MI5 thread... only need to play a bit to make universal... with all source we can make somthing, but no have time to play with all tutorial available on XDA or Youtube...
Only way to make device much smoother and battery friendly or Perf/Warm destructor...
We all know about the emmc bug that has affected our note 4, as I saw on the "Fix'd" thread someone solved their emmc brick by baking the motherboard, like people did when their PS3s were failing to reball the GPU.
So this means that at least some instances of the bug, if not most, are caused by the emmc being desoldered by the heat of the CPU, which is soldered on the same side of the PCB, right under it (Samsung ePOP technology). As an introduction to my possible "solution" to it I want to say this: I recently bought the Note 4, after I broke something on my Note 3's mobo. A big difference between the two that I observed is that on my N3 i could undervolt about 25-30 mV lower than the stock values and that was it,more and it would reboot, I forgot the pvs bin no. , but it was a either 3 or 4, the good ones. Well, on my N4 after I checked my pvs bin ( pvs10 ), I put the PVS10 voltage table on the phone , and that was -65 mV compared to stock, after that I undervolted -25 mV more and everything is perfect : No deep sleep problems, no audio problems with screen off (While also using V4A), 85K Antutu Score and CPU Throttling Test is showing a very big improvement on the heat dissipation: it now underclocks more easily (2.64-2.45-2.22-2.0 but it mostly stays at 2.45 and from time to time going to 2.22-2.0 for a few seconds), using stock values it was dropping to 1.72 after 2 seconds on the test then going up to 2.0 for a few moments then back to 1.72 and mostly staying there. I want to add here that the Sub-Ghz voltages can be undervolted even more to the values of the pvs15 table without any problems.
So , my "solution", not really a solution but more like future proofing the health of the ePOP package (S805 AP with RAM and EMMC soldered right on top of it) is to :
1. Check your pvs bin.
2. Apply specific voltage table values in KA/Synapse .
3.Undervolt -25 more and test for stability, and if your phone can handle it, undervolt even more, to the maximum possible ( sillicon lottery ).
P.S: If you are more experienced user and have H/W capabillities, you can also add what I did to my Note 3: I opened the phone, removed the pink heatpad it had, and in place of it I put a decent amount of Arctic MX-2, added a very thin aluminium heatsink (from car ECU) , then a blop on the heatsink, one on the CPU and voila! In the cpu throttling app the phone was sustaining 2.57 Ghz for like 2-3 minutes , then underclocking a bit and then back to 2.57 Ghz; idling at around 30 C even hitting 27 C, and when normal using going around 40-42 . Sadly while doing test (i had a few attempts before getting the perfect amount of Paste ) I broke the headphone band, then when replacing that I broke the MIC and Speaker little gold legs on the USB pcb, and then just sold the display and batteries and bought our beloved Note 4, which is a really nice upgrade!
EDIT : h t t p : / / w w w . myfixguide . c o m /manual/samsung-galaxy-note-4-disassembly/ it shows here the said package , they only mention "3GB RAM chip and Qualcomm APQ8084 enclosed chip", but as I read the technology combines RAM and MLC (the internal memory) on the same chip.
Hi bro, do we need custom kernel to do that, just the undervolt thing ?
i'm wondering whether emmc can be upgraded to a faster one, which will then make the phone way snappier?
Here is a 100% hardware fix for this issue that anyone can do with no tools or special equipment.
It really works. Give it a try. ?

I have this tabled for a long time, but as i rarely used it i didn't bother with it much. From day one back in 2014 the tablet was sluggish and laggy, today is just unbearable even for browsing. So i have decided to take a look of what can i do.
I have installed the latest (10.26.2019) LineageOS-14.1-Deathly with gapps nano.
I have installed CPU Throttling Test from the play store and start testing to see what's going on. I saw that the CPU Throttle instantly (like in 10-15 sec max) from 1900mhz to 600mhz, and this is where the sluggishness comes from, the CPU is constantly throttled no matter that you are just looking at a simple web page.
I started playing with the Deathly Adiutor and under-voltage the cpu, set the max to 1400mhz and this is where it is stable as it is. At 1400mhz constant 100% CPU stress the CPU temps are around 90c (at 95 the cpu starts throttling). Anything above 1400mhz even with under voltages CPU results in throttling within 1-2 min, but even like that at 1400mhz and GPU set to be always used and at minimum of 480mhz (with setting in dev options to always use gpu for 2d composition) the performance was really much much better then the stock settings.
I have continued to play with it and noticed that if i apply pressure with my fingers on the back panel just below the camera where is the most hottest, the temps are dropping 10-15C, so i have opened it and i saw the issue.
The issue is that the metal shield radiators does not make a good contact with the thermal pad on the back panel, and thus can't dissipate the heat well. This may variety from user to user as some back panels will make better or worse contact, but its far from ideal.
Its good that i have some spare thermal pads around and i have applied them, and the result is perfect, drop in 12-17Cfrom stock setup under continues stress.
As a final result i have managed to bump the CPU from 1400mhz to 1600mhz with 1087mV voltage and at max 84C (down from around 90 at 1400mhz) at constant 100% CPU stress. The performance gains are around 100 to 150% (At around 42-47k GIPS up from 20-25k GIPS stock in CPU Throttling test). Additionally i have to say, its extremely easy to open the back cover panel.
Furthermore, i made an video to see how it runs and the settings i use.
https://youtu.be/_UJdjPDQB00
I'm attaching before and after the mod photos.
Quick followup, i have run 3D Mark benchmark and PCmark, see the screenshots below. Managed to achieve the world fastest Tab S, enjoy

Its not the minimum CPU frequency that gives you the performance boost, its the maximum frequency limit at 1600mhz down from 1900mhz, as i explained, to gain the performance, you need to avoid CPU from overheating and throttle down itself to the ground. That's why the max frequency with the thermal pads and improved thermals is 300mhz below the stock 1900mhz, and without the pads my max stable frequency were 1400mhz (500mhz below stock).
The minimum frequency will only smooth out initial animations and things like that, but don't have much of an impact on the overall performance. With that said, increasing the minimum frequency ofc will eat more battery and you don't need it, you can safely set it to 650mhz (as low as it allows) and depending on your kernel governor policy should have the same or better battery life. As i said, the main gainer is preventing the CPU from overheating at 1900mhz and throttle down to 650mhz where it sits most of the time with stock settings.
In fact if you limit your max frequency to 1400 or 1600mhz depending on your stable thermal results, and set minimum to 650mhz, you will see the performance gain AND significantly increased battery life due to that CPU does not go to 1900mhz and does not eat that much power and voltage. You really need to fine tune it depending on your needs, but at stock CPU throttling down to 650mhz and staying there is an manufacturer (Samsung) failure, and if i were discovered this when i bought it, i would wanted refund, as they advertise 1900mhz CPU which almost never works at that frequency.
I tested this method on other tablets and phones, and while it happens on other devices to throttle down after 5-7 mins (not after 15 sec), i have never seen to throttle more then down to 80% of the advertised frequency, but the Tab S goes almost immediately down to 35% where it stays and cripple the device. Its really really bad engineering from Samsung.
Going to try this.
Thanks
A lot better .
What thickness of thermal pad should I buy? Probably will buy from Amazon unless I need to make a trip to Microcenter. Thanks for this suggestion @nauvho

Well as you can see on the picture, the CPU bed already has one black pad by Samsung by default which is around 0.2/0.3mm i think, but it does not make contact, so i put on the CPU radiator 1mm pad and on the other radiators i put 0.5mm to equalize in case my pad is too thick. Your guide should be how easy is to close the back-plate, if you need too much force you may need thinner. So i guess you can take 0.3, 0.5 and 1mm pads.
effing A
Wow
Applied the same settings that you show in the video and WOW! It's like a new tablet. I didn't even put thermal pads.

installed Kernel Adiutor from playstore with which I can lower the freq, and for 1600 it works 1-2min at 27-28000GIPS then starts to throttle

Why are you using MM? Also, did you noticed that center pad is thicker and side ones are tinnier? what are your CPU temps? Also probably due to MM, but I'm getting around 42gpis (average) at 1.6, but you should really check your pads placement, thickness and temps, put the CPU under load note the temps before throttling down.

I'm using MM since I don't know if it worth to upgrade; does this LineageOS work well...all features (cam, scanner, soud etc) works with it?
used 1mm pad over the cpu... 0.5 otherwise (china made); also removed the small factory pad and placed another pad patch there; the back cover heats well and I assume that the heat doesn't have where to go.
since it's not throttling at 1600MHZ (almost 100%, take a look at the pic)...from where to get more than 28GIPS?

I don't think removing the stock black pad were a good idea, I did not removed mine, my pad is next to it. Also CPU throttle app is not reliable to monitor cpu temp (at least for me) , you should do it by starting the throttle test and then switch to deathly auditor and monitor the temp and clock there or other app like CPUz or Aida. Look at the video how I monitored the temp. The CPU will start throttle at 93-95c so your temp of 81 cannot be accurate if it throttle. Didn't you said that you throttle at 1.6 in your previous post?
Regarding the performance I think it might be eigher app difference between mm and 7.1 or due to MM itself. And yes everything is working perfectly for me with lineage, camera, fingerprint, everything is fine and it is mile better then MM imo.
installed 7.1
pcmark 4330 with your mods.
so the thermal pads doesn't matter on MM.
from my testings on 7.1 the boost in pcmark comes form setting max freq 1600 + undervoltage (3000->3500), and another boost...by setting the lower freq to 1600 (3500->4300)

About the pads, they matter only if the CPU temp under load drops when you apply pressure with fingers on the back cover as i explained in my first post, but idk if this apply to all tablets or just mine. The boost comes from not throttling the CPU down and being stable at maximum possible frequency. The CPU can go up to 1900mhz and beyond (2.1 by spec), but the cooling is not enough for that frequencies.
I think that adding an 0.5-1mm copper heat pipe thru radiators or copper heat pads similar to flagship phones might push it to 1.9, will order some someday and try it.
now it will be interesting ?% it's the termal mod in this boost, which means, performing the test in PCMARK only with steps 1+2:
1. LineageOS-14.1-Deathly
2. Deathly Adiutor (which requires step 1) + CPU max freq 1600 + undervoltage at that freq + CPU min freq 1600
3. Thermal pads added inside the box.
Since I started with thermal pads...I can say that in MM it doesn't matter.
-after upgrade to 7.1 as I said..PC...MArk around 3000 (thermal pads mounted)
-after setting max freq 1600 + undervoltage I got a boost in PCMark to 3600
-in addition, with min freq 1600...got another boost..to 4300; in this turbo state..the battery drains quickly, but the interface it's fast like the wind.
PCMark doesn't use CPU at 100%, it counts also how fast cand do certain short tasks...and this matters because if CPU it's in it's low power states..it loose time to rise its freq and do the calc at full power.

Thermal mode does matter alot, CPU thermals is everything, the lower temps are, the higher frequency you can push the CPU, more frequency = more performance. As i said, without the thermal pads i could not get 1.6ghz to be stable, only 1.4 were stable-ish.
In stock rom, CPU governor and states are set according to the temps with the stock cooling. But if you don't change settings it wont change much. However Samsung engineers did a terrible job with those default settings, so as i explained in my first post only doing the software changes had dramatic impact on the performance because you get the CPU stable even at 1.4, but the thermal mod push it further to 1.6
The true performance benchmark is the 3DMARK (my screenshots 3 and 4 for score "ice storm unlimited" test and "Sling Shot" test) this will push your CPU and GPU to the max, PCMark is more about daily use performance and also can be used to measure battery performance between different settings.
Yes leaving CPU with minimum of 1.6 will drain battery more quickly naturally, is using more power, i leave mine at 1.2 as minimum, but minimum speed should not matter much in benchmarks if you are using the same as mine CPU governor. CPU governor basically tells the CPU how to behave, like how quickly to rise the frequency, for how long and etc.
A month ago or so, i had this random period of time where perfZ started to show "-" for temperature ( i assume its gpu temperature because it doesnt match with battery or cpu temp from another app) and my phone was heating up much more in games but so was the performance was way better.
Normally after thermal throttling kicks in and device reaches heat equilibrium, my battery would sit around 38-39C, cpu at 42-43C. But in that time period where it showed "-", my equilibrium was battery sitting at 44C, cpu at 47-48C. Phone was considerably hotter to touch but you could still game on it. And performance was way better, it would fall to 50fps min instead of 40fps, which is very noticable. (Dont have exact numbers maybe a bit better)
Idk how this happened as it randomly happened one day but does anyone know how to make this work? My device isnt rooted. (s10+ exy)
(Small note: Using game plugins at max performance or custom doesnt help, maybe they arent optimised for dead by daylight, because thats the only game i play)
