Today we are adding a new feature to Steam Deck, enabling it to complete all active downloads in a new display-off low-power mode, before going to sleep. This feature is enabled by default when Steam Deck is plugged in to power, and can also be enabled on battery power in Settings > Power.
Display-off downloads are accessible in two ways. While Steam Deck is downloading content, pressing the power button now brings up a new dialog, asking whether you'd like to continue downloading with the screen off. Select Continue, and Steam Deck will go into the new low-power download mode. In addition, Steam Deck will automatically go into this mode after an idle timeout.
While in this mode, if you press a button or move Steam Deck, a new status screen will be shown with download progress (see above). From here you can fully wake Steam Deck or let it continue downloading with the screen off.
When this feature is active on battery power, Steam Deck will automatically go to full sleep mode if the battery level falls below 20%.
This feature is now available on Steam Deck in the Beta and Preview channels. Let us know what you think in the comments.
