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?
Space. The 64gb micro already has little usable space for games, and hibernate requires that you write all of the contents in RAM to disk. Rather than fracture their feature set by model options, Valve instead decided not to bother with it (just guessing).
That, and as another person said, hibernate just hasn’t enjoyed great support under Linux. There are definitely other issues that need to be fixed with the Deck, like the audio bug while docked and the need to disable half the CPU cores in order to have good emulation performance.
Yah all good questions and good responses. Suspend is great for this handheld, but as @PlasticExistence@beehaw.org mentions linux isn’t great at suspend out of the box and having a very configurable embedded system like the steamdeck lumps it in this basket.
