Pokémon GO Raid Bonuses Updated: Everything You Need to Know
This speed bonus applies to all Raids going forward, replacing the team-contribution bonus. Completing normal raids faster will earn you more Premier Balls.
The Raid Tiers were also consolidated to make room for Mega Raids. There are now only four raid tiers: one-star, three-star, five-star and Mega.
One star raids will have the same difficulty as before but will feature more Pokémon usually found in two-star raids. In addition, the rewards for two-star raids will be applied to one-star raids.
The same is true for three-star raids, taking on the Pokémon and rewards for four-star raids as of the update. Basically, the first four raid tiers were squished into just two, taking the better rewards each time. Five-star raids are the same.
The Gym Defender bonus did not change.
