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?

I recommend using hibernate (suspend to disk): your computer will "sleep" for 10 years without draining. The only cost is about 7 seconds to boot on modern hardware. For short interruptions with instant wakeup, you can still use light sleep states.

It combines perfectly with LUKS-encrypted root and swap partitions: your data is safe even if someone steals your computer and swakes it up.

Hibernate with an encrypted swap and systemd boot takes forever for me. How do you manage in 7 seconds? How much RAM do you have?

32 GiB. I decided against a 96 GiB model with hibernation in mind.
