We have just shipped an updated Steam Deck Client to the Preview/Beta channel. GeneralAdded Battery Charge Limit control to Settings->PowerThis option allows you to set a maximum charge limit for your Steam Deck.Limiting the charge limit to 80% can be beneficial for long term battery health. This can be useful if your Steam Deck is constantly being charged (i.e.
Batteries really do not like to be at 100% charge. So if you use your SteamDeck mostly docked, it will be always at 100% charge and this prevents this. It’s a nice, useful feature.
Because you can now just set the charging level to 80%, plugin your Deck into your dock and it will stop charging at 80% and then just use passthrough power.
I think it is because it is also harmful to be at 100%, not only to charge there. So a docked deck will be longer in a harmful state than a mobile one. In the case of a mobile deck there is a clear use case for charging to 100%: Longer battery life.
But you are also correct: If you’re not using the full battery charge during everyday operations, you should also enable that and also buy one of those 4-5m USB-C charging cables
