This was how shitty Windows 11 was when I started using it in October 2021:

It ruined my battery from 5 hour life to 30 min life within 2 days. Later, I switched back to Windows 10 that very week but... my battery already deteriorated and won't go back to pre-Windows 11.
Now I am with windows 10, got a good battery + CMOS battery. Back to my usual 5-7 hours life like I first bought my Laptop.
No thanks, I am okay with Windows 10 forever.
