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?

Shouldn't modern laptops have temperature sensors and just deal with it in some way? I had this happen to me a few times with my old Thinkpad from 12 years ago. Threw it into the backpack in a rush and an hour later I'd pull it out, hot and doing something I didn't want it to do... But it never suffered any kind of damage from that. Was just very annoying.

    You can't interrupt Windows Update either. So, rock meets hard place?

    Sure 😆 In the meantime I found a solution for all the Windows Update debacle. Bought a newer laptop, went home and just wiped the entire SSD before installing Linux. Now I don't get any dual-boot or Windows update. Also goes to standby 100% of the time. ¯_(ツ)_/¯

    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.
