Power Up

In Pokémon GO, the player can Power Up (Japanese: 強化 strengthen) a Pokémon using and Candy to increase its. This is analogous to raising a Pokémon's level in the core series games, but no explicit numeric level is ever given for Pokémon in Pokémon GO.

Mechanics
Powering Up a Pokémon raises its stats, which is reflected on the Pokémon's summary screen in its HP and CP. Upon pressing the Power Up button, the game will show how much the CP will be increased and ask the player to confirm.

Each Pokémon effectively has a Power Up "level" that determines its CP multiplier, a value used to calculate the Pokémon's stats and. Each Power Up increases the Power Up level by 0.5, up to the undefined's Trainer level + 2. The cost to Power Up a Pokémon increases every two levels (or every four Power Ups). The half-circle gauge on a Pokémon's summary screen indicates how close it is to this limit. The highest possible Power Up level is 40. If a player is to be traded a Pokémon that exceeds their Power Up limit (Trainer level + 2), then both players will see a warning that the Pokémon's level will be reduced to the limit. In addition, if a Pokémon at a half level is traded, its Power Up level will be lowered to the nearest whole number,.

Pokémon can only be obtained at whole-number Power Up levels, with possible levels depending on how they are encountered.
 * Wild Pokémon can range from Lv. 1 to the Trainer level, capped at Lv. 30
 * Weather-boosted wild Pokémon can range from Lv. 6 to the Trainer level + 5, capped at Lv. 35
 * Pokémon hatched from s will be at the same level as the Trainer level at the time the Egg was initially obtained, capped at Lv. 20
 * Pokémon encountered in a Field Research or Special Research will always be at Lv. 15, regardless of Trainer level
 * Pokémon in the bonus challenge after a Raid Battle will always be at Lv. 20, regardless of Trainer level
 * Weather-boosted Raid Bosses are set to Lv. 25

If a Pokémon is transferred from Pokémon GO to GO Park in Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!, its level will be equal to its Power Up level, rounded down to the nearest whole number.

Levels
Powering Up a Pokémon requires both Stardust and Candy. The amount of Stardust and Candy required for the next Power Up will be shown on the Pokémon's summary screen. If the Pokémon is at the maximum Power Up level for the player's Trainer level, then the player will not be able to Power Up the Pokémon. Each time a Pokémon is Powered Up, are recalculated using the CP multiplier, which increases with level. Lucky Pokémon require only 50% of the listed Stardust costs to Power Up.

The following table shows the CP multiplier that corresponds to each Power Up level, along with the costs needed to Power Up to the next level. Cumulative costs show the total amount of Stardust and Candy needed to Power Up a Pokémon from level 1. Cells that have been grayed-out denote values that cannot be attained or used, but are still coded into the game for conventional purposes.
