So many times I forget to plug the deck or someone uses the charging cable for something else and I come back to play the next weekend and the deck is at 0%. Why doesn’t the deck have a deep sleep or hibernate mode on by default like my laptop or iPad?
PC games and Steam in general have too much going on in the background for it to hibernate. If it did, you’d have to wait 30 minutes for updates, shade caches, etc. just plug it in when not in use for some time, or shut it down. It’s two clicks to power off fully.
The Steam Deck doesn’t do updates or background shader caches in the background while asleep.
