Pokémon Go is at long last expanding its trainer level cap.
At present, the maximum level for trainers is 50, but from 15th October this will be increased to 80 to rebalance the existing curve for more frequent level ups due to less XP required for each level.
As a result, some trainers may jump in level automatically if excessive XP past level 50 has already been gained. Niantic will share more details on how many levels in the future, but noted no trainers will drop in level.
Any tasks for Level-Up Research for levels 41 – 50 will be removed, while new tasks will be added for levels 71 – 80. Trainers at level 70 or higher will have an increased chance of becoming Lucky Friends with others.
