Trainer Battle (GO)

Trainer Battles in Pokémon GO

Trainer Battles (Japanese: トレーナーバトル Trainer Battle) are a feature in Pokémon GO that allow players to challenge other players to a 3-on-3 battle. This feature was first introduced on December 12, 2018 and received a major update on July 19, 2019. On January 28, 2020, the GO Battle League was launched to introduce competitive, online Trainer Battles.

Battle Challenge

Players can challenge any player in close proximity by scanning another player's Battle Code from the Battle screen. These Battle Codes are different to the QR codes used to add Friends, with a new one being generated every time the player signs into the game.

Players can also remotely challenge Ultra Friends and Best Friends by sending a Battle Challenge through the Friends List. The Battle Challenge feature can be disabled via the settings page. Battling also counts as a daily activity that may increase Friendship level.

Leagues

Players can choose to battle from three different Leagues:

League Max CP per Pokémon Unlock requirements
 
Great League
1,500 None
 
Ultra League
2,500 3 Pokémon with 1,500+ CP
 
Master League
No limit 3 Pokémon with 2,500+ CP

Each player selects three Pokémon to battle with. Pokémon will automatically be recommended based on their CP in relation to a League's criteria. Preset teams can also be made for each League from the Party screen.

Ditto and Shedinja cannot be used in Trainer Battles.

Battle mechanics

Similar to battling a Gym, the player can command a Fast Attack by simply tapping the screen, which also charges up energy for the Charged Attack meter. However, there are several ways Trainer Battles differ from Gym and Raid Battles:

  • Moves often have separate power and energy boosts or costs
  • All Fast Attack durations are measured in 0.5-second "turns"; Charged Attacks have no duration
  • All attacks have a 30% damage boost
  • No weather bonuses
  • No dodging
  • Receiving damage does not generate energy
  • When a Pokémon faints, the player has 12 seconds to choose a Pokémon before the next Pokémon in sequence is automatically sent out.
  • Switching out Pokémon mid-battle has a 60-second cooldown period. Switching Pokémon also resets all stat changes.
    • This countdown does not stop during Charged Attacks or when the opponent is selecting a Pokémon to send out

The battle has a four-minute timer and the last 20 second countdown is displayed. If the timer runs out, the player who has the most Pokémon remaining is declared the winner. If both players have the same number of Pokémon remaining, the player who has less damage to their remaining Pokémon wins the battle. Time spent charging up a Charged Attack is not counted against the timer.

Pokémon used in Trainer Battles will always start off with full HP and, after battle, are reset to the HP they had previously; however, fainted Pokémon cannot participate.

Battles against Team GO Rocket members use the same Trainer Battle format. However, the player's Pokémon are not fully restored at the beginning, and medicine is required to restore any HP lost during the battle.

Activating Charged Attacks

 
Using a Charged Attack (left) and a Protect Shield (right)

Once the Charged Attack meter is full, the player can tap the icon to cast a Charged Attack. Activating a Charged Attack will initiate a five-second minigame in which type icons start appearing on the screen in a pattern specific to the Charged Attack's type. The more icons the player manages to swipe, the more damage the Charged Attack will deal. Since February 15, 2019, certain Charged Attacks may increase the user's stats after use; on March 19, 2019, Charged Attacks that may decrease the target's stats were also introduced.

A damage multiplier is applied to the Charged Attack depending on how many icons the player successfully manages to swipe.

Score Min. Accuracy Multiplier range
Base 0% [0.25, 0.5]
Nice! 30% [0.5, 0.75]
Great! 60%
70%
[0.75, 1]
Excellent! 95% 1

If both players attempt to cast a Charged Attack on the same turn, then the Pokémon with higher Attack will go first. If there is a tie, then priority is given randomly.

For a list of move data in Trainer Battles, see list of moves (GO).

Protect Shield

At the same time when a Pokémon is using a Charged Attack, the opponent also has the option to use a Protect Shield to mitigate all incoming damage. Each player can use up to two Protect Shields per battle. Using a Protect Shield will not prevent stat changes, to either the user or target, from an opposing Charged Attack.

The Protect Shield's size depends on the Pokémon's size, e.g. a Wooper's Protect Shield will be smaller than an Infernape's Protect Shield.

Battle Training

Battle Training is a type of Trainer Battle where the player battles one of the team leaders, Blanche, Spark, or Candela, as an NPC. It can be accessed from the "Training" section at the bottom of the Battle view.

Team leaders use Pokémon that have the maximum 15 IVs across all stats and are powered up to the highest integer level that meets the league's CP limit. In the Master League, the team leaders' Pokémon are powered up to Lv. 55, which is unattainable by players. Each of their Pokémon has one Fast Attack and one Charged Attack randomly selected from the current move pool.

Team leaders will always send out their Pokémon in the same order in every battle and never switch out. In Great and Ultra Leagues, team leaders will never use their Protect Shields; in Master League, they will always use a Protect Shield against the player's first two Charged Attacks.

Rewards

After a battle, both players will receive a randomly-selected reward bundle. Each day, players can only receive rewards from Trainer Battles three times and training against a team leader once. There is also a 10% chance to receive a second reward bundle, regardless of outcome. Losing against a team leader always yields  300 instead of a random reward, but outcome does not affect the reward from battles against other players.

Rates for training against team leaders have been approximated based on empirical data.[1]

  • Prior to July 19, 2019, a player using a Charged Attack would instead repeatedly tap the screen for three seconds to strengthen its power. If the player did not tap the screen at all, the Charged Attack would only deal 1 HP damage.
  • Prior to December 11, 2019, if both players attempt to cast a Charged Attack at the same time, priority is given to whomever selects their team first
