GO Battle League

GO Battle League is a feature in Pokémon GO that allows trainers to battle opponents around the globe in online Trainer Battles. The feature is released on January, 2020. It is only available to Trainers level 10 and up. Only one Pokémon of a single species can be assigned to a Battle Party.

Since April, 2020, the GO Battle League leaderboard was introduced to show the top five hundred Trainers in the world.

Due to coronavirus outbreak, trainers now do not require walking or PokéCoins to unlock battle sets in GO Battle League.

Participation in GO Battle League requires unlocking a GO Battle League set, which grants you access to play a series of 5 matches. Your first set is free, and you can unlock future sets by walking 3 km.

If you do not want to walk, a "Battle Now" button will appear, giving you the option to unlock one set by spending, or  if at least 2 km, 1 km or less than 1 km remaining respectively.

You can view your progress towards earning a set on the Battle page, plus you'll receive an in-app notification and see a red dot on the Main Menu's Battle button when you’ve unlocked a set. Trainers can only unlock a maximum of 5 sets per day, but can still accumulate distance for the future's set.

If one loses all 5 matches in a set, they can continue playing in that same set until scoring a win for up to 15 losses, after which they will move to the next set.

Ranks and Ratings
Rank is a measure how many matches you've played and/or won. Once you attain a new rank, you cannot drop below it for the rest of the season. Reaching rank 7 can see your rating. Losses do not affect rank but lower matchmaking rating. Ending a season with a higher rank results in better end-of-season rewards.

Only playing the GO Battle League global matching system influences the GO Battle League Rank.

Rewards

Development
Battling has been a core part of the Pokémon universe since the very beginning. This new feature that will build upon Trainer Battles, the current form of player vs. player battling that exists within Pokémon GO. Like many Pokémon GO features, GO Battle League will encourage players to get out and explore the world with Pokémon. Trainers will be able to walk in order to earn entry into the GO Battle League, then battle opponents from around the globe through an online matching system and rise in the ranks of the league. This feature should make the Pokémon GO battling experience more competitive and accessible to more Trainers.
