Looks like Samsung is not stopping in disappointing me.
Delivery of my s22 was delayed, argh had to eat it and wait 2 weeks longer, but that was not so painful as I still had my s20 working pretty well and fine.
Now what is really strange after launch of GPUWatch on S22 I can see HIGH CPU/GPU usage on idle !!! CPU = 50% +, GPU never drops below 60% !!!
Where comparing these numbers with my s20, they're too high (s20 CPU ~20%, GPU ~5-10%)
What is happening???
Indeed I did 
but haven't done any particular steps to resolve the issue.
It found out that GPUWatch tool was a root cause for other issues I have experienced.
What helped me was to stop using the GPUwatch tool, then gave some more time to Android OS and Samsung customization and all save battery features/tool/algorithms to start work and do their jobs. Afterwards all things started to work a lot better.
My device also got hot because of exynos cpu, but usually only when I'm playing games, regarding the battery drain after a few applications were put to sleep or deep sleep by Android OS, it improved and works a lot better (meaning on 85% it can easily handle all day standard/commo usage till the end of the day since morning without the need to recharge the battery during the day)
