After a long time of users asking, Valve has actually added an official Battery Charge Limit setting in the latest Steam Deck Beta update so you no longer need to use third-party tools.
Almost no modern device does a traditional S1-3 sleep. They all do S0 standby/modern standby in windows 8+ parlance. The system is on the entire time. So “waking up” to go to hibernate is basically the same as doing it from a normal on state.
I personally wouldn’t want that, at least not if it’s on a game.
Hibernate would be great as it’s a slightly longer restore, but should work the same (if you are willing g to sacrifice the disk space)
Being able to pick up the deck and know it will have battery left would be really nice. It drains pretty fast in sleep mode.
It can’t dump a save state to disk? I guess that would be difficult on a normal OS.
That’s basically what hibernate is. Shouldn’t be hard to offer as an option.
The difficult bit is having it wake from sleep to hibernate itself. I suspect that would require hardware.
