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’ve been using it pretty consistently for years, I achieve uptimes upwards of 60 days like this. The downside is that it takes kinda long to enter that state and there’s a chance that it fails to enter it (though it doesn’t crash, just goes to the screenlock), especially on my laptop - it refuses to go into hibernation unless I kill most webbrowser windows, especially stuff like YouTube.
And you do need a pretty large swap space; with those super long uptimes, even swap size = ram size isn’t always enough, because sometimes the swap space is actually used as swap and not just as hibernation image storage.
Using swap for hibernate was always insane to me…
Twice your RAM is the old adage.
