Valve develops battery charge limit feature for Steam Deck to enhance battery health

Valve is developing a Battery Charge Limit feature for the Steam Deck, which will prevent the device from charging beyond 80%. This aims to enhance battery health over time, a feature that was previously absent. Currently, the Steam Deck supports battery passthrough, allowing it to run directly from a charger when plugged in. This feature helps protect the battery from excessive wear, as it only charges when the battery drops to 90%. There is no confirmed release date for the Battery Charge Limit, but it is in active development. Users can currently enable a similar feature through unofficial methods if they choose.
