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.
