The latest update for SteamOS is here, after months of development in beta. SteamOS Version 3.7.8 includes a lot of fixes and improvements on a system level, and will also introduce a battery saver feature for the Steam Deck for the first time.
The new battery saver option is called Battery Charge Limit, and can be found under the Power submenu in Settings. The feature allows users to set a maximum charge limit for their Steam Deck, with a maximum of 80% charge recommended for devices that are usually left on charge, or that rarely have their battery fully depleted.
This kind of feature, designed to prolong the working life of lithium-ion batteries, is already commonly implemented in devices like mobile phones and laptops, and now is starting to become more common in the gaming space. Nintendo recently revealed that the Switch 2 will have a similar feature, which will stop the hybrid handheld console from charging once it reaches 90%.
