Pokémon Scarlet and Violet utilize an auto-battle system similar to that of Pokémon Legends: Arceus, which was made available earlier this year. The system can be a quick way to level up your entire team because it enables you to send Pokémon out into the field to automatically battle wild Pokémon. Let's Go is the mechanic's name.
The Pokémon in your party's lead position will be sent out when you press the right bumper (R), even before the system is explained in-game. Your Pokémon can be directed to particular targets by tapping the appropriate bumper. It's automatic for your Pokémon to engage in combat with other creatures it meets or to gather items.
Yours may occasionally decide to move forward in the direction of nearby Pokémon. Your Pokémon could fight any gathering of Pokémon, which resulted in enormous XP gains and quick level gains.
Your Pokémon will either win or lose the first round of auto-battle. Whoever wins the fight depends on the type and level of both your Pokémon and the opposition's. No user input is required, and the battle interface never appears.

The rest of the party will receive half of the experience points earned by your Pokémon. In these conflicts, Pokémon's health might be lost. The message "[Your Pokémon] wore itself out and came back to you" will appear instead of them collapsing. That Pokémon won't be able to auto-battle again until it has been healed when this message appears.
Auto-battles prevent Pokémon from being captured, but winning materials can be used in the TM Machine at Pokémon Centers to create new TMs.
You can also use the right bumper to direct your Pokémon anywhere while still sending them out without engaging in auto-battle. Walk With Pokémon is the name of this. They'll walk with you as long as you don't get too far away from them.
Pokémon Scarlet and Violet are currently available for the Switch.
