How to Set Up Steam Deck for the First Time

Getting the Steam Deck set up for the first time takes about 15 minutes. Here’s the complete process, from unboxing to playing your first game, with a few first-session optimisations worth doing right away.

Step 1: Charge First

Plug the included 45W USB-C charger into the Deck before turning it on. The LCD model ships with around 50% battery; the OLED ships closer to 80%. Either way, charge to 100% before the first session, it calibrates the battery indicator. The Deck charges fully in about 2,3 hours.

Step 2: Initial Setup

Press the power button. The Deck boots into the initial setup wizard:

1. Language and region, select your language
2. Wi-Fi, connect to your home network
3. Steam account, sign into your existing Steam account or create a new one. Use the on-screen keyboard (press the Steam button if it doesn’t appear automatically)
4. Updates, SteamOS will check for and install updates. Let this run, it can take 5,15 minutes depending on your connection speed

After updates, the Deck reboots into Gaming Mode, the main Steam interface. Your Steam library is now accessible.

Step 3: Install Your First Games

Press the Steam button → Library to see your Steam games. Games with a Steam Deck Verified badge (green checkmark) are confirmed to work well on the Deck. Pressing the down button on the D-pad or the right trigger lets you filter by Deck compatibility.

Select a game → press A → Install. Games download directly over Wi-Fi. Download speeds depend on your connection, a 20GB game takes about 5 minutes on a 500Mbps connection.

Step 4: First-Session Settings Worth Changing

Enable Night Mode

Press the three-dot button (Quick Access Menu) → Display → Night Mode. Enable it and set a warm colour temperature. Handheld gaming often happens in dim rooms, night mode reduces eye strain significantly.

Set a Frame Rate Target

Press the three-dot button → Performance → Frame Rate Limit. Set it to 40fps or 60fps depending on the game. Uncapped framerates drain battery and cause inconsistent performance. For most games, 40fps is a smooth, battery-efficient sweet spot.

Check Display Brightness

The default brightness is often higher than needed indoors. Press the three-dot button → Display → reduce brightness to 30,50% for indoor use. This meaningfully extends battery life.

Enable Automatic Suspend

Steam button → Settings → Power → set the suspend timer (e.g. suspend after 5 minutes of inactivity). The Deck’s sleep mode is instant and reliable, pressing the power button resumes exactly where you left off. Let it sleep rather than leaving it on.

Step 5: Insert a MicroSD Card

If you have a microSD card, insert it now, the slot is on the bottom edge of the Deck. SteamOS will detect it and prompt you to format it for use as game storage. After formatting, go to Steam → Settings → Storage → set the microSD as the default install location. New downloads go there automatically.

See our microSD card guide for the best options at each capacity.

Step 6: Explore the Interface

The Steam Deck’s Gaming Mode interface is similar to the Steam Big Picture mode. Key navigation:

• Steam button: Opens the main menu, library, store, settings, friends
• Three-dot button (QAM): Quick settings, volume, brightness, performance, Wi-Fi
• View button (two squares): Opens screenshots, Steam overlay in-game
• Right trackpad: Mouse cursor, useful in menus and Desktop Mode
• L4/R4 back buttons: Programmable, set to any button combination

Step 7: Try Desktop Mode

When you’re ready to explore: Steam button → Power → Switch to Desktop. This opens the KDE Plasma Linux desktop, full file manager, browser, and app access. You can install emulators, non-Steam games, and productivity apps here. Switch back to Gaming Mode via the desktop shortcut or by restarting.
