Why does Linux have such a terrible sleep? (programming.dev)

In 8 hours it uses 20% of the battery. When Windows or Mac are put to sleep, the damn things can sleep for a week! This is the case with Linux on multiple laptops.

Is there some kind of manipulation going by ring -1 that detects Linux is running? Is Linux not respecting some procedure and kissing a step?

True, kernel developers should resolve the Secure Boot issue with hibernation, but the development focus is on servers, not laptop computers. Also, hibernation should probably use a dedicated hibernate image file instead of requiring a huge swap partition. That being said, it works regardless of hardware capabilities if you turn off secure boot and just configure a LUKS-encrypted SWAP partition. You should figure this out before you install the OS.
