Gym Overview and Strategy

Gym Basics
  • Once you hit level 5, you can choose a team and begin taking on gyms. Click here if you want the basics on how gyms work!
  • Up to 20 gyms can be held at once.
  • Pokemon can't be added to gyms when they are under attack.
Spinning
  • Counts as a daily stop bonus.
  • You can't spin a gym Pokestop using a GO plus.
  • Spinning a gym gives 2-4 items, +1 bonus item if you are on the same team as the spinned gym. More items are rewarded based on gym badge bonuses.
Gym Defense Rewards
  • A trainer is rewarded one coin every 10 minutes per Pokemon placed in a gym.
  • Time is always rounded down to the nearest minute, for example, a Pokemon placed in a gym for 19 minutes will net 1 coin.
  • You can redeem a maximum bonus of 50 PokéCoins per day. If you have more than one Pokémon return from Gyms in a single day, the maximum bonus for the day is still limited to 50 PokéCoins.
  • Gym rewards reset at 12:00AM your local time, the same time as the daily streak bonus.
Gym Motivation
  • Every Pokémon on a Gym has motivation, a measurement of the Pokémon’s desire to defend the location.
  • A Pokemon initially placed in a gym doesn't start with max motivation. An estimated 8-9% CP, 10% motivation is dropped upon placement.
  • As a Pokémon loses motivation, its CP will temporarily decrease, making it weaker in battle.
  • When a Pokémon’s motivation reaches zero, it leaves the Gym and returns to its Trainer the next time it loses a battle.
  • Trainers from opposing teams battle to reduce the motivation of the Pokémon on the Gym.
    • Estimated: 27 - 28% motivation lost per battle.  This means it takes about 3 battles per Pokémon to fully defeat it.
    • A Pokémon with 0 motivation has 20% of its maximum CP.  For example, a 1,000 CP Pokémon will be kicked out after reduced to 200 CP.
    • A Pokémon with less than 20% motivation (36% of maximum CP) will have its CP shown in red and will likely be kicked out after one fight.
  • Pokémon gradually lose motivation over time.
    • Estimated: 10% motivation lost per hour for Pokemon >3000 CP and ~1.1% if < 3000 CP, heavily favoring Pokemon below 3,000 CP.

    Berries
    • Reinforce a friendly Gym by giving Berries to the Pokémon, increasing the Pokémon’s motivation and making it harder for rival teams to capture the location.
    • You can only feed a max of 10 regular berries to a Pokemon for an unconfirmed time frame of about 30 minutes.
    • Feeding a Pokemon multiple berries in succession reduces the amount of motivation gained per berry, each one is half as effective as the previous one. Unconfirmed cooldown of 30 minutes before this reduction resets.
    • Feeding a Pokemon ANY berry nets +20 stardust per berry fed.
    • Golden Razz Berries fully restore a Pokemon's motivation.
    • Feeding any Pokemon (ally's or your own Pokemon) any berry can possibly award candies of that feed Pokemon.
