Unfortunately, since no one in the community could help me with my problem, I had to reset it to the first state where i bought it.
While I'm at it, I tried a few things to figure out what was causing the battery drain. I actually reset the machine 4-5 times for this 😄
I found out that the bios update is not the blame, feel free to update to version 412 here.
Only the last Windows update and the last updates via MyAsus cause the fast battery drain.
That's why I turned off "Windows Update" via msconfig and services.msc, so Windows can no longer make an update until this problem is fixed on the part of Windows and i also turned off the Updates in the MyAsus App under Settings.
The only problem I have is that Armoury Crate cant be really installed, because it wants to install "peripharel components" on every reboot of the system and doesn't really turn on, but that doesn't bother me because I can still set the performance to "Silent" via the shortcut on the keyboard.
If I now set the performance to "Silent" and deactivate the Nvidia 3050 Ti via the device manager, I have a really cool battery life.
Here are a few screenshots ( The language is here in German but you can see the numbers after the battery percentage so you know what thats mean ) :
Here you can see my battery life at the beginning, before i used it
And here you can see it after i used it ( the usage here is not gaming, its office tasks so browsing in web, coding, checking emails and so on ) for 4 hours without power cable, it still shows me 8 hours and 44 Minutes Battery Life. Thats huge !
Additional info maybe, i dont hear any of the fans here, also not in Chrome which has a huge ram usage. The notebook is not warm its very cool, its very quit.
I give this info because the last updates which causes the problem there were the fans very loud and the notebook gets very warm even if you did nothing and the usage of cpu and gpus was near by 0 % .
I hope i can help other person in this community, who has the same problems with this very expensive and very cool piece of hardware.
