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.

Battle Challenge

Players can challenge any player in close proximity by scanning another player's Battle Code from the Nearby 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.

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.

Team GO Rocket Grunts encountered at invaded PokéStops are battled in the 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.

Leagues

Players can choose to battle from three different Leagues:

League Max CP per Pokémon Requirement to unlock
Great League GO.png
Great League
1,500 None
Ultra League GO.png
Ultra League
2,500 3 Pokémon with 1,500+ CP
Master League GO.png
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
  • Switching out Pokémon mid-battle has a 60-second cooldown period.
  • When a Pokémon faints, the player has 12 seconds to choose a Pokémon before the next Pokémon in sequence is automatically sent 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.

Activating Charged Attacks

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

Once the Charged Attack meter is full, the player can tap 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. At the same time, the opponent also has the option to use a Protect Shield to mitigate all oncoming damage. Each player can use up to two Protect Shields per battle. Since February 15, 2019, certain Charged Attacks may increasing the user's stats after use; on March 19, 2019, Charged Attacks that may decrease the target's stats were also introduced. Using a Protect Shield will not prevent stat changes that result from using a Charged Attack.

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

Score Icons swiped Damage multiplier
Base 0% ×0.25
Nice! 30% ×0.5
Great! 60%
70%
×0.75
Excellent! 95% ×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.

Battle Training

Battle Training is a type of Trainer Battle where the player battles Blanche, Spark, or Candela as an NPC. It can be accessed from the Battle Training on the Nearby screen.

Team leaders use Pokémon that have the maximum 15 IVs across all stats and are at the highest integer Power Up level that meets the CP limit. 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 whenever possible.

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 GO Stardust icon.png300 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]
