Didn't work, but I managed to find a fix

I installed a terminal app then with root privileges I wrote

iw phy

I saw that the channels are blocked some how.

I then wrote

iw set reg RU

disabled and enabled wifi, and it worked. I then installed a script manager app to execute at each boot with root privileges this command

iw set reg RU

When executing the command iw reg get I also noticed that the phone automatically grabs (at boot) the region settings based either on my IP address or my GPS location which is really annoying.

On the lock screen it said 2100mA at 9V and 45 minutes to full charge from 45%. Did not have time to double check this yet usually it said 2100mA and 5.0 V. Do we have quick charge on zuk z2 with Jaguar? This is so fing awesome !!!!!!

I just both an S9 Plus for my wife and used it's cable to charge my phone on a QC 3.0 changer (https://ae01.alicdn.com/kf/HTB1zR3D...-EU-Plug-18W-Universal-Mobile.jpg_640x640.jpg). On the same charger with different cable on lock screen i get the 5.0V though. Will test some more and report back.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] MtBlackstar:
Well the truth is we don't have qc3.0 that's given by Qualcomm

Instead we have a degraded version of QC 3.0

It doesn't have any name in order to save the royalty

And stuffs nor does it reach the speed of Real QC 3.0

No custom ROM implement the real speed of charging

Of our device in zui.

Though most say they do get to original limit when the screen is off.

As a piece of advice just don't use any third party charger or cable it may very well **** ur device

I don't know how to deal with this problem anymore

I lowered the thermal temp quite a bit, and tried to monitor temperature ingame, as it turned out battery temp was never higher than 48C, the CPU can still reach max frequency at 82C, and the phone just shutdown whenever it want. The game is not even putting any load to the GPU at all with the lowest graphic setting selected

having a throttling driver from older driver isn't good for modern chipset nowadays....

i have a terrible experience with custom thermal stuff for arm64 qcom soc...

it's a bad idea to keep using those driver for kryo..., SD820 have their own system that couldn't be changed with any driver...

if you wish to see what was caused it, do a logcat

it's really helpful to get a specific thing

mostly ( except jaguar ) doesn't have a shutdown thing problem out there, we ain't adding any thermal driver or any significant changes
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
I remember you complaining even on Nougat that thermal settings didn't seem to change anything for you. So, maybe it is a device specific problem.

I bet you are not using Oreo 8.1 unstable Gapps on miui, which could be the reason for your problems. Thr fact that reboot helps you is an indication that one or more apps fail to release a wakelock after exiting.

the shutdown caused by kernel panic seems to be a different case: it usually followed by a white led and must be exit by holding the power button for 8-10s

the shutdown Im experiencing is just pure *poof-it's-downed*
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] faizauthar12:
does we are able to change the maximum thermal throttling?

it doesn't even exist at CAF kernel...

it's up to you won't take some advice from other person, world isn't centered at you at all

you're giving a "kernel panic" search , and it's not always related to "Heating"

the reason of kernel panic it depends on the thing they are doing

driver crash, dtsi won't load up properly.. etc

and none of them providing pstore, so we couldn't clarify it at all....

as you can see it here OP, it's not goes to kernel panic
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
Uncheck 'apply on boot' in voltages, reboot and see, if that helps.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
Well. Kernel panic is usually preceeded by a shutdown. Isn't it? Lol. Also, we don't know, if her shutdown is related to heating, as certainly 82 degrees does not trigger a shutdown. She is also known for experimenting with huge voltage changes (50-100mv), which can certainly cause shutdowns.

But rest assured that your expert opinion has been noted. Big thanks. :)
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] pipyakas:
Well guess what - I didn't touch voltages. It doesn't matter either, I tried playing with both undervolt and not, still shutdowns can happen anywhere anytime

The reason I doubt it was heat related is because after recovering from the shutdown, if I continue to boot up the game and resume playing it would shutdown even faster. One can only assume heat and thermal throttle are to blame in this case

---------- Post added at 07:37 PM ---------- Previous post was at 07:35 PM ----------

Preceeded by a shutdown, but a shutdown doesn't always lead to a panic - I expecienced both multiple time and there're clear differences, as well as very repeatable (shutdowns by games, kernel panic by undervolting)

I also stopped messing with undervolting on jaguar for a while since dev really insisted on "it would only harm you - you don't know what you're doing - leave it to the true pros"

[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
Check permissions for that game: see, if access to sensors or network is not limited. Also, make sure you are not using some modded version, which is trying to do something inappropriate.

Edit: also, I don't think I have ever told you 'leave it to the pros' or 'you don't know what you are doing', although, you put those in quotes.

[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
You want me to give you a log for an issue I don't have? Lol.

By the way, Jaguar has a per app toggle to restrict access to sensors and network.

Also, Jaguar is being downloaded at about 6000 times per month rate, which, as noted by other users, is more than all other roms combined. And yet, there were just 2-3 complaints...

So, who has to move on, buddy? :)
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] pipyakas:
It's just implied meaning like authar12 said, plus another guy threw a post of dorimanx quoting an enginneer saying the exact same thing: don't bother. Yet many, many people still do undervolting/overclocking around the world, across pc or mobile for years now. This phone and the sd820 is literally the first time voltage control is so difficult, I still have my old xperia z1 compact and it's behaviour with undervolting is very straight forward: enough voltage for a frequency, or it won't work, period

Although things seem to have calmed down, please remember that if development discussion is not bringing the results you desire, rather than becoming sarcastic, insulting, personal, or petty, just move on. Unsubscribe from the thread, seek your answers somewhere else, or agree to disagree and don't bring the tone of the thread down to bickering and beating your chest over who is more right or more intelligent or more experienced.

Everyone in Xda are at different levels of knowledge, and if someone else is trying to share that knowledge, but it is not being received well, or two ideologies just aren't lining up; agree to disagree and change the subject, end the discussion, or find a better way to resolve any issues.

Airing dirty laundry, the 'he said, she said' back and forth has no place in development threads, subtle insults, mud flinging and calling others out, even if you feel a certain thread is fairly worthless or barely qualifies for development, has no place in Xda. Even if it is true, and a developer is creating something that is dangerous, REPORT it, don't flame them for what you perceive as incompetence.

Which is better, friendly development at a lower level OR rude development at a higher level? We could have the best devs ever but if everyone is rude, what's the point.

Please, find a way to show one another respect, even in your differences. Tearing someone down never makes you a bigger, better person, but helping someone grow and learn certainly does. If you try to help, and someone doesn't want to hear it, move on. Find another user who is willing to be taught and helped.

THAT, is what Xda is all about.

Sorry this was long, but this thread has a bit of a history of users ignoring Forum Rules and "brawling" in the thread. Let's move away from that and help each other. If this thread isn't your cup of tea, find another. If someone is trying to help, accept that offer, or kindly turn it away.

There is never justification to treat others with disrespect or insults. Before it gets to that point, simply REPORT the issue.

tl;dr

we are all at different levels in our journey on Xda, always be respectful, even in disagreement,

if it gets bad, be part of the solution and REPORT it don't be part of the problem and add to it.

you are responsible for your actions, they are responsible for theirs, no one forces the other to respond disrespectfully
