Power up

In Pokémon GO, the player can power up (Japanese: 強化 strengthen) a using and to increase its . This is analogous to raising a Pokémon's level in the core 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 a CP multiplier, a value used to calculate the Pokémon's stats and . Each power-up increases the level by 0.5, up to the 's Trainer 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 currently Mega 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.
* The cost to power up
* The cost to power up
* The Candy 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 its HP, 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 has fainted, 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, its are recalculated using a new CP multiplier.
If a Pokémon is transferred from Pokémon GO to GO Park in Pokémon: Let's Go, Pikachu! and Let's Go, Eevee! or to Pokémon HOME, its resulting level 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 the level 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 current Buddy Pokémon. The CP multiplier for Lv. 55 is only attained by team leaders while in Master League. 
 require only 50% of the listed Stardust costs to power up. 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.

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