Valve has released a new update for the Steam Frame VR headset that significantly extends battery life. With the launch of SteamOS 0.4.3, which is essentially a regular SteamOS version optimized for the Snapdragon 8 Gen 3 Arm-based SoC, Valve has pushed the Steam Frame headset into a more power-efficient mode, achieving up to 12% longer battery life. While this is a theoretical maximum boost, the actual battery life will heavily depend on the framerate the VR headset is outputting and the content being displayed. In practice, you can expect a modest increase in battery life for average usage tasks. Valve has likely made low-level optimizations in its software stack to enhance the Steam Frame's power efficiency.

Additionally, SteamOS 0.4.3 for Steam Frame now includes an eye-tracking option that is limited to single-eye tracking. Users can enable this in VR Settings > General > Track Dominant Eye Only, but note that it requires enabling "show advanced settings." Other fixes include improved focus behaviors when interacting with grab/resize handles and resolving an issue where controller bindings weren't loading in certain games, including Thumper and Google Earth VR.As Valve continues to optimize the software stack, expect further refinements. SteamOS for Steam Frame is currently not at version 1.0, running only on version 0.4.3 for now. With the release of version 1.0, we can anticipate Valve's polishing of the VR headset and optimizations to be nearly perfect.
