Is possible to confirm the issue I am experiencing is due to thermal sensor? if so. is it possible to change the default threshold using adb or some other method that would not require booting the rom.
When I plug the phone in to charge I get a your device is overheated, charge will resume when cooled down, etc. message.
When I try to boot I receive the custom animation and then flash of the ROM starting up abruptly followed by shutting down.
I ran a dumpstate and found the following:
LGE charging scenario : state 0 -> 3(2-1), temp=79, volt=4326, BTM=1, charger=1, cur_set=1600/-1, chg_cur = 26
I'm not sure but I believe the temp should be closer to 25...
running XDABBEB 3.1.2

[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.
Thanks alekthefirst for his contribution here
USE THIS GUIDE ON YOUR OWN RISK AND DISCRETION. YOU MIGHT DAMAGE THE SILICONE CHIPS / YOUR SIM CARD / SD CARD AFTER PROLONGED USE UNDER HIGH TEMPERATURE CONDITIONS.

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)

doesn't work on charging thermal protection. these settings are for tegra 3's thermal protection by controlling throttle when the heat becomes too high.

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.

There are files for each group of two cores under

listed as
throtle_table0
throtle_table1

hope you can....!
good luck.......
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 a strange problem which more and more frustates me!
ROM: Tonyp build version 4
Kernel: 2.6.39.4-Kowalski-Exp
Baseband: LGP990AT-00-V20l-262-XX-Oct-21-2011+0
WLAN: normally OFF
Situation:
If i use my LG frequently (e.g. each 30 min once) there is no problem.
If i leave it untouched (e.g. more then 1-2 hours) it shuts off. Overnight it is everytime gone/off. I i try a call i get the mailbox so it is really shutted off.
Using Power off/on will normaly not start it, rebuilding battery also did not help in most of the cases. But connecting to power supply gave me everytime the possibility to start the phone. Battery is then also not empty and has still x % and i can again normally work with the phone.
What i try:
- Deinstall several Apps (e.g. Anti-Virus Lookout)
- max CPU set back from 1,2 to 1 GHz
- disabled zRam
- disabled all other memory settings like Tonyp memory optimization
- Kowalski Manager: disabled all WLAN power settings
Any suggestions are welcome!
Updated section:
After clearing cache through recovery and doing a hard reset, the uAh has gone back to 3142000. Standby time seems good with the battery losing 7% overnight. It does charge quite quickly from 0-100 in about 2h. The previous heating issue remains with cpu monitors showing that the cpu jumps to high clock when I touch the screen. I don't see any change in which apps use the most battery with the screen taking up the most as before the problem started.
The heat appears to be what is draining the battery but I can't find any single app that causes it to ramp to max.
Pictures:
No-frills is set to stock settings to see how the phone handles the actions
2nd picture is when phone is idle
3rd picture is immediately after swiping through a few tabs and scrolling through some pages in the app which causes cpu clock and load to increase
Old sectionFor when battery uAh was low)
I've had this Z1 for about 11 months. I can only get around 2.5h on screen time with regular usage. The battery uAh was only 1848000 Recently it fell to the 1700s. Calibration appears to reduce the value further. The phone seems to heat up in about a minute or two no matter what app is running.
The phone is rooted on stock 4.4.2
I have tried updating to Lollipop before but received an error due to rooting, so I don't think anything changed.

sounds like it's time for you to replace your battery.
You may try to disable the "input boost frequency"
By default when you toch the screen, cpu frequency of two cores instantly jumps to around 1400 to preventing any lag but it seems to use more power and causing heat
I have disables this and since then I'm no longer have any heat issue and also the battery life is so much better now but you may exprience a little lag while scrolling on heavy web pages but thats all
Btw i'm on .157 and using Kernel Adiutor for cpu tweaks
You may disable this by the app mentioned above or by editing sys.somc.touch_perf_kick=1 from 1 to 0 in buid.prop or adding this line
EDIT 2: I made a backup for my phone's data through TWRP (Recovery) and then factory reset through TWRP (as my phone's factory reset button in the settings was not functioning). All was good as soon as it booted, took awhile, but it booted. I then restored the backup and bam. The problem was solved. It may have been a problem with the system, but the Logs had shown nothing and nothing would report the mass amount of CPU usage. So a simple factory reset was all I needed.
I'm not sure what I did to make my phone mad.
I'm currently Rooted and S-ON. I'm using ElementalX as my custom kernal and the OS is stock. It started happening when I received my phone back from a repair store as my charge port was short-circuited (overloaded the port). The System would respond incredibly slowly and die quickly (100% to 85% in less then 15 minutes). I went into CPU-Z and noticed that my CPU was at a constant 100% Usage running at 384 MHz. Now, my device runs at a constant 60%-100% at 2.04 GHz (Overclocked by 200 MHz). It does throttle between 1-2 GHz but never goes below 1 GHz for more than 3 seconds.
I checked every app I could and every app reported 100% CPU usage but that NO APP was recorded using CPU above 3% AT ALL.
A thing to note is that in order to (guessing) replace the charge port, they had to remove the bottom speaker. In this case, they destroyed the bottom speaker which does not work anymore. It only makes a *CLICK* sound every half-second. What's weird is that CPU usage increases by 30-50% when the device tries playing sound through the speakers. I'm pretty sure CPU usage increases when playing music to the speakers but not by that much? Anyway, I want to keep resetting the device as a last resort since I need to backup my photos and videos but I can't since the CPU is being hogged and can not turn on MTP.
Please help me!
EDIT 1: A quick check at CatLog makes me certain that the device is unable to "read mount points" when connected to a USB port. Any ideas?
did you check your govenor setting? make sure it is "ondemand" or something else, not "performance"

I tried putting it on Performance thinking that the extra juice will keep up but alas it completely froze my device, in some cases crashing it and causing it to restart. It is set to OnDemand right now.

performance is just for bench marking, not good for daily use. Ondemand will raises your clock speed in heavy task, and lower it when not needed to save battery
You're talking to a tech geek too. Anyway, any ideas on how to find out what's using all that CPU?
I've given up.. I'm going to just back up the Data through TWRP and restore it later. Please delete/lock this thread.
Hello guys:
I've a strange behaviour of cpu. After a while, the Little CPU stuck at 1401 mhz like min frequency. It's not the same problem that stucks in max freq.
I don't know why it is. I have a theory .. when I connect the USB Type C adaptor to headphones or the USB cable to charge, after a while the cpu rises the low freq from 633 mhz to 1401 mhz and stucks here like the min freq.
Somebody with a similar issue or solution?
Thanks a lot!
is your phone FP sensor is FPC ?
they also have CPU stuck bug but only 4 Little CPU stuck.
it occasionally happen when use FP to wakeup from deepsleep or wakeup while Quick charging.
Just checked my little cores and they were stuck at 1401. Restarted the phone and they are back to 633 MHz, and now no matter what I try (unlocking several times with FP, from deep sleep and what not) I can't get them stuck at 1401 again. Could it be something else?
I got the FPC sensor, running September patch.

Please try when you disconnect your phone before charging or listen music with earphones with jack 3.5 mm adaptator. The CPU back to stucks at 1401.

I've charged and used the headphone adapter multiple times since the last reboot and my little cores still go all the way down to 633MHz.
I have only noticed this bug once and have not been able to reproduce it, it's very rare and inconsistent for me
I still have 1401Mhz stuck problem. Did anyone solve it?
do you resolve it after restart?
I do. something is triggering it at my device but I'm unable to understand what. It's not often I get it.
I don't use fingertip sensor.

I switched off smart lock and fingerprint, it has been 9 hours since last restart and no problem. O do agree with you, it's still unknown CPU freeze. I'll try to switch on smart lock, lets see what happens)
I got it twice in the past 2 days. Weird. I hadn't gotten it in weeks. I did enter battery saver mode yesterday, maybe that messed things up with the cpu. And I also installed rootless launcher which is what I think triggered it the first time
Well, today I received the Pie update. after install it, the 1401 MHz bug still continues. Anyone else ith this bug and the Pie didn´t fix it? It is weird, I wait for the Pie and I was thinking that it feixed the bug, but no!

I'm facing this issue too. Updated to Pie today as well.
But is this software or hardware issue?
Same on Redmi 6
I have the same problem on a Redmi 6 at around 900 MHz according to GSam. It seems to appear after I have disconnected the charger. Not everytime.
Restarting the device does not reset the frequency. Stopping it and starting again after a minute or two does. Weird and annoying !
