Overview
- The new mode is live in the SteamOS Beta and Preview channels and is expected to move to the stable build after testing.
- Users can trigger screen-off downloads via a power-button prompt during active transfers or let it engage automatically after an idle timeout.
- The feature runs by default when the device is plugged in, can be enabled on battery under Settings -> Power, and forces full sleep below 20% charge.
- Pressing a button or moving the Deck briefly shows a status screen with progress, from which users can fully wake the device or continue in low-power mode.
- The update delivers a long-requested quality-of-life fix that Steam Deck owners have sought since the handheld’s 2022 launch.
