If you don’t plan on using your Deck for two weeks or longer, enabling Battery Storage Mode can improve long-term battery health and prevent the battery from fully discharging while your Deck is sitting idle. The only thing to remember is that you have to charge or discharge the battery to around 50–70% before enabling this mode.

You can enable storage mode in your Deck’s BIOS. To do this, first power down your Deck. Next, press and hold the volume + button and press the power button until you hear a sound, and your Deck boots into the BIOS.

Once in the BIOS, you can navigate with the D-pad, select and confirm actions with the A button, and go back with the B button. Now enter the “Setup Utility” tab.

Next, navigate down to the “Power” menu and select the “Battery Storage Mode” option. Press the A button to enable the option.

After you confirm your choice, your Steam Deck will enter battery storage mode and shut down.

To exit Battery Storage Mode, all you have to do is hook your Steam Deck to a charger and turn it on with the power button.
