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 would expect overheating protection to occur at the hardware level: first downclock the CPU and forcibly just halt if heat gets critical for too long.

Sure but the update can already have done some stuff, leaving your machine in a half-updated and maybe corrupted state. If downclocking doesn't work there really isn't a good solution here.

Edit: oh wait there is, DON'T UPDATE WHEN SLEEPING. And on top of that, just don't update without my explicit approval at all. Thankfully I run linux where, if it's not the default already, it's a config value away.
