Power up

From Bulbapedia, the community-driven Pokémon encyclopedia.

InPokémon GO, the player canpower up (Japanese:強化strengthen) aPokémon usingStardust andCandy to increase itsstats. This is analogous to raising a Pokémon'slevel in thecore series games, but in Pokémon GO, no numeric level is visible for Pokémon.

Mechanics

Each Pokémon has a level that effectively counts how many times it has been powered up. Each level corresponds to aCP multiplier, a value used to calculate the Pokémon's stats andcatch rate. Each power-up increases the level by 0.5, up to theplayer'sTrainer level + 10. The cost to power up a Pokémon increases every two levels (or every four power-ups). The highest level a Pokémon can be powered up to is 50.

A Pokémon that is currentlyMega Evolved cannot be powered up.

Process

Players can power up eligible Pokémon by clicking the "Power Up" button on the Pokémon's summary screen. Upon pressing the Power Up button, a pop-up screen will show the following information:

The Pokémon's current CP, with an arrow pointing to the CP it would have after Powered Up.
TheStardust cost to power up
TheCandy cost to power up
TheCandy XL cost to power up, if applicable

The pop-up screen displays this information for one power-up by default. The screen also displays "-" and "+" buttons, allowing players to decrease or increase the number of power-ups to apply to the Pokémon. Once players have chosen how much to power up their Pokémon, they can click the "Power Up" button on the pop-up screen to apply the changes. Clicking the "Cancel" button on the pop-up screen will return players to the Pokémon's summary screen without making any changes.

Stat changes

Powering up a Pokémon raises its CP, which is derived from itsHP, Attack, and Defense; as such, some combination of these stats will also increase. The CP and HP changes are reflected through animations shown on the Pokémon's summary screen. A Pokémon whose maximum HP increases by powering up will also gain an equal amount of remaining HP; consequently, if the Pokémon being powered up hasfainted, it will be revived with a remaining HP equal to that amount.

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 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, itsstats are recalculated using a new CP multiplier.

If a Pokémon is transferred from Pokémon GO toGO Park inPokémon: Let's Go, Pikachu! and Let's Go, Eevee! or toPokémon HOME, its resultinglevel will be equal to its level from Pokémon GO, rounded down to the nearest whole number.

CP multiplier

The following table shows the CP multiplier that corresponds to each level, along with the costs needed to power up from that level. Cumulative costs show the total amount of Stardust and Candy needed to power up a Pokémon from Lv. 1. Pokémon that have reached Lv. 40 will require Candy XL instead of Candy to power up further.

Levels above 50 are unattainable by powering up, but have been coded into the game since thelevel cap was increased from 40 to 50. The CP multipliers for Lv. 50.5 and Lv. 51 are only attainable by a Lv. 49.5 and Lv. 50 Best Buddy, respectively, deployed as the player's currentBuddy Pokémon. The CP multiplier for Lv. 55 is only attained byteam leaders whileBattle Training in Master League.

Lucky Pokémon require only 50% of the listed Stardust costs to power up.Shadow Pokémon cost 1.2× the listed Stardust and Candy to power up, while Purified Pokémon only require 90% of the listed Stardust and Candy costs (rounded up). Stardust reduction bonuses for Lucky and Purified Pokémon can stack, meaning that a Pokémon that is both Lucky and Purified only costs 45% of the normal Stardust amount to power up.^[1]

Eternatus requires a lot more candy than any other Pokémon to power up once.

Initial level

This section is incomplete.
Please feel free to edit this section to add missing information and complete it.
Reason: Confirm what happens if a player below Level 25 purifies a Level 25 or above Shadow Pokémon

Pokémon can only be obtained at whole-number levels. If a Pokémon with a fractional level is traded, its level is rounded down.

The following shows the possible range of initial levels for each encounter type.

Encounter	Level		Weather Boost
Encounter	Minimum	Maximum	Weather Boost
Wild spawn	$1$	$\min (T r a i n e r L e v e l, 30)$	✔
Hatched	$\min (T r a i n e r L e v e l, 20)$		✘
Field/Special/Timed Research andResearch Breakthroughs	$15$		✘
Raid Battle	$20$		✔
After defeatingTeam GO Rocket	$8$ ^{[note 1]}		✔
Purified Pokémon	$\max (\min (T r a i n e r L e v e l, 25), O r i g i n a l L e v e l)$		✘
Trade	$\min (T r a i n e r L e v e l + 2, ⌊ O r i g i n a l L e v e l ⌋)$ ^{[note 2]}		✘

↑Prior to November 7, 2019, Shadow Pokémon could be encountered at lower levels.
↑A traded Pokémon will normally retain its original level, but its level cannot exceed its new Trainer's level + 2. If trading would reduce a Pokémon's level in this way, both players will be warned that its CP will be reduced as a result of this limit.
