Pokemon GO: Walkthrough Guide for CP, When to Power Up and When to Evolve

Pokémon GO

I’ve been playing lot of Pokemon Go (I’m level 21 right now), and one of the biggest questions I get from people is when to evolve their Pokemon. If you’re looking for information on stardust, candies and transferring Pokemon, first see this guide.

First, let me show you the Combat Power (CP) gauge. The whole arch (pink arrow) shows you the current max CP this Pokemon can have. The white part (yellow arrow) shows how close its current CP is to the current max. This helps you tell whether the Pokemon is a strong one. You want the CP to be as close to the max as possible.

final-3

I learned this the hard way, as it’s hard to tell early on, but the max CP of all your your Pokemon (and all Pokemon in the wild) increases as your avatar levels up. This means that no matter how strong you think your Pokemon is, it will always have the ability to get stronger (the current rumor is that the CP caps out when you reach level 30). If your goal is to get the strongest Pokemon of each kind, this means you want to wait before powering up or evolving your less common Pokemon. Unlike in the old Game Boy games, Pokemon here do not grow with you. Only their potential does. And as Pokemon get stronger, it costs more stardust to power them up. Yes, it may seem like 20,000 stardust is a lot. But it’s not when each power-up costs 2500 and only gives you a few CP. That stardust can go real fast if you’re not careful. It’s best to save it up for powering up Pokemon that are already strong and just need a little help maxing out their CP.

Let me use my Dodrios as an example.

I caught a Doduo when I was just a young whippersnapper of a trainer. I thought it had the highest CP possible and therefore would be so strong when I evolved it. So I evolved it. (You can evolve a Pokemon at any time, as long as you have enough candy to do so.) This was it then. I couldn’t power it up anymore. I thought I got an amazing Pokemon. It had 448 CP, which seemed like a lot to me at the time.

final-208

This is that same Dodrio now. It has little over half its max CP

final-209

And this is another Dodrio I have close to its current max CP.

final-210

I come across a lot of Doduos, so it’s no big deal. But I did learn from this to use my stardust very sparingly. It’s exciting to get a Pokemon with a high CP, but unless it’s one I know I’ll see plenty of, I won’t evolve it. And I don’t power any Pokemon up unless I think it’s worth evolving right now or is already evolved and close to current max CP. Here’s what I do instead:

I always keep at least one Pokemon of each type I caught in my bag, no matter how weak. But when I catch duplicates, I keep the ones with the highest CP and transfer the others to turn them into candy. As I get stronger, the Pokemon I meet have a higher CP. I have a much better chance of catching a Pokemon that might be worth evolving when I catch it. If I catch a few of the same Pokemon very close to their current max CP, I keep all of them until I get one that’s considerably stronger.

So if your goal is to have strong Pokemon to use in gyms, I would hold off on using any stardust until you’ve reached at least level 20 or so. Any stardust you waste early on just means you need to earn more later. Each Pokemon you catch only gives you 100 stardust, no matter how rare or hard it was to catch. So keep that in mind before you spend all your stardust to power up your Pikachu you got as a starter. It’s not worth it. And it’s not worth wasting your few precious Pikachu candies to evolve a weak Pikachu into a Raichu. It just makes sense to wait. Patience, grasshopper!

You might even get lucky and catch a fully evolved Pokemon with a very high-CP, saving you both stardust and candy.

Basically, before powering up or evolving a near-max CP Pokemon, think about your own level and whether you’ve been leveling up quickly. If you have been, it’s worth waiting because that max CP will soon grow. If you’re at a high enough level that your next level-up is a long way off, it’s more worth it to invest in your current Pokemon.

Keep in mind that it’s not so black & white as just keeping the highest CP Pokemon. Two of the same Pokemon can have different max CPs and HP but be close to the same CP. They also might have different attacks, so look at those as well. Pay close attention so you don’t accidentally scrap the better one. Take these two Sandshrews I caught. One has a current CP of 424 but his Max CP is lower than the 444 CP. But the 424 has higher HP. So you might want to hold onto both of those and decide later whether to evolve one (or both). The 444 has a higher max CP, though, so will likely higher HP in the end, since it’s got more room to grow. So the 444 is still likely your better choice despite the lower HP. It’s possible that hatched Pokemon are better than caught ones.

final-5

final-6

Here’s another example. The 191 Caterpie has a higher HP than the 199 Caterpie, and possibly even more room to grow than the 199. So the 191 is likely more worth evolving.

final

final-1

Then there’s these two Nidorans just one CP apart. But the 367 looks like it has more room to grow than the 368 and it also has a higher HP.

final-2

final-3

Then these two Mangetites are only two CP apart, but the 326 has more room to grow and a higher HP. So that one has more potential and is the better choice to hold onto.

final-4

final-5

And between these two Nidorans, the lower CP one has more HP and looks like it could potentially be the better one with a little powering up.

final-6

final-7

And these two Oddishes. The lower CP has higher HP and could also catch up with the other’s CP to become the better Pokemon.

final-8

final-9

So the main point with the above examples is to compare the CP to max CP as well as HP before tossing out one Pokemon over another.

Also think about how often you see a specific Pokemon and how many candies you have for that Pokemon. If you rarely see them, just hold off. If you see them often and have a stockpile of candies, you can spare the candies to evolve the Pokemon even if he gets replaced in the not-so-distant future.

Right now I’m at a high enough level that if I see an uncommon Pokemon with a near-max CP, I might power it up and evolve it. For instance, this Psyduck I turned into a Golduck when I was level 20. I knew it would be a long while before I find one that’s much stronger than that, because my next level-up was 50,000 XP away. So I made the call to use some stardust and candy to power him up to his current max CP and then evolve him for some instant gratification. Even though his max CP will continue growing, it will be at a very slow rate at this point. So it doesn’t cost me that much stardust to keep him at max CP. If you want to make sure you waste nothing, you could wait even on a Pokemon like that. But then you need to figure out what level is a high enough level for you to feel ready to start evolving and using them in gyms.

final-211

final-212

As you can see here, when I got to level 21, his max CP went up a drop. But now I need 75,000 XP to get to level 22, so it was still very much worth evolving him. Continuing to power him up won’t cost too much stardust or candies. But if they cap out at level 30, you may decide that level 20 is still too early for you. You might want to evolve him but not waste any stardust to keep him strong. That’s entirely up to you. I’ve been catching enough Psyducks that I may just leave him as is now and assume I’ll catch a stronger one much later.

final-213

On the other hand, this is my starter Pokemon, Charmander. I haven’t powered him up at all because it would take way too much stardust and candies to ever get his CP comparable to one I can catch in the wild right now. So instead he’ll be transferred to the professor and turned into candy eventually.

final-214

When it comes to common Pokemon like Pidgeys, Zubats, Spearows and Rattatas (and Doduos for me), if you have hundreds of candy, go ahead and evolve some of them. It gives you some good experience points, especially if you activate a Lucky Egg before evolving them all. But I strongly suggest you don’t waste any stardust on them. They’re not worth it (sorry, but they really aren’t.)

Now, if all you care about is filling out your Pokedex and you know you won’t care later down the road that your Pokemon are weak, go crazy and evolve all your Pokemon the second you can. But don’t say I didn’t warn you. 😛

NOTE: If you have a lot of a certain Pokemon (like Pidgey), you can get experience from evolving some of them. Evolving a Pokemon gives you 500XP. If you activate a Lucky Egg before you do all your evolving, you’ll get 1000XP per evolution. So you can try saving up some Pokemon like Pidgeys and Caterpies, while transferring most of them. Some Pokemon only need 12 candies to evolve, so you can get a lot more out of them. Just turn the evolved Pokemon into more candy (don’t waste stardust powering them up) and keep evolving the new ones you find. But be careful not to accidentally turn your strongest ones into fodder. 😉

Keep your starter its a xl, xl yes size matters… a lot. Look into sizes… its a huge factor in combat.

I have noticed that some egg Pokemon appear to have higher max CPs than other Pokemon. For example I have a 491 Psyduck I hatched from an egg that has a 1900 power up cost. I also have a 484 Psyduck I caught that has a 2200 power up cost and a more complete circle. Have you noticed this as well? I had previously been using stardust upgrade cost to decide which Pokemon to evolve but if my 491 just has a higher max I should evolve that one. Or will my 484 Psyduck pass my other one when they evolve because it is more powered up?

Regarding your Sandshrews, the 444 is clearly the better Pokemon. Why? Look at it’s arch. It’s already at 444 and it’s further back on it’s arch than the other one, meaning it still has room to grow even though it’s already stronger. If you powered it up a few times so that their Arch’s were the same and put them on the same “level” the 444 would be likely end up equal or slightly better in HP but superior in CP by a good amount.

This is one of the key things that many people seem to be missing. It’s not the current CP and HP, its the CP and HP relative to the Arch position. Think of the Arch position as the Pokemon’s level. Higher or equal CP/HP and further back on the Arch means a better Pokemon that is stronger at a lower level and therefore worth powering up even if the current CP isn’t very high. In with time and investment these “high potential” Pokemon will grow and end up better than the vast majority of Pokemon you catch at higher CP values due to trainer level, even though they started small.

Right now I have a Pidgey that hatched from an egg at 56 CP that has continuously outclassed every other Pidgey I have caught as I powered it up and it grew to it’s current 328 CP.

I was wondering if the stardust cost was any indication on the cp after evolving the pokemon. If the one with higher stardust cost actually evolved yo a higher cp pokemon. The artical only talked about first form but could the cp range also indicate the evolution form of the polemon so a first form pokemon higher on the cp bar will end with a higher cp after evolution compared with a similar pokemon with similar cp lower on the cp range?

Evolving Pidgey, Rattata, Weedle, Spearow and shit is the best way to level up fast as they provide great XP points when attached to a Lucky Egg. I do not have Pokestop within a 10 min range of my home. But i do have my little walking run of 5 km. 2 lucky egg, 2 incense, tons of pokestop and egg incubator. I’ll cash over 25k XP points without being particuly good at throwing balls or even fighting a gym (im under level 20). but continiously evolving those common pokemon….

Hey AppUnwrapper,

First i have to say great work u did there , nut i have some questions :
Lets say we have unlimited stardust and candies, wouldt it be the best if we evole the weakest pokemon with 0 % arch ? im mean lets get the example with eevee and vaporeon:

Eevee gets 17 cp for every powerup but vap gets 40 per power up so when i evolve it rifght at 0% arch then ich have the whole 100 % arch to power it up with 40 each time

With this the other question is : can you PU more times when u have higher lv ? so when i go from 0% to 100 % at lv 1 i need 2 powerups and when i try it at lv 20 i need 40 powerups or ist the % per PU that it grows the same every time ? because when its the same % then ur methode is better

i hope u understand what i mean 😀

Marcus

ok i will make an example for the second question :
Trainer A has a valpeon with 0% arch and gives it a power up which increases the arch by 5 %, so he does it 20 times and geht to 100 % . each trainer Lv up the arch drops by 20 % and he gives 4 powerups so its at 100 % again . This goes on until lv 10 trainer , so he did a total of 56 powerups

Trainer B has the same valpeon ( so really exacly the same ) but waits until lv 10 and then starts powerup , will he also need 56 Powerups to go full 100 % or does every powerup still increases by 5 % so that he only has 20 PUs ?

if its every time 5 % icrease per powerup then at the end with a valpeon at cp 1 its:

Trainer A : 56*40 +1 = 2241 CP
Trainer B : 20 *40+1 =801 CP

guys try download the iv calculator in app store, the one that is blue colour, when u use it, u will see the arch actually have more stops before complete as u levelling up, this means as u level up, the full cp of pokemons that u catch is also higher, as an example a level 12 player caught a pidgey with 0 cp n a level 15 also caught a pidgey with 0 cp, if both of them level up their pidgey to the max, the level 15 will have more CP and HP as his pidgey have more archstops and can be level up a few times more than the level 12 pidgey,

OK i try it with and example :

Trainer A is lv1 and got a vaporeon at 1 cp .Everytime he PU , the arch gets filled 5% , so after 20 times the arch is at 100 %. Every lv up the arch go down and he can PU anothe 4 times . He does it up to lv 10 , so its 56 PU in total :

Vaporeon : 1+56*40= 2241 cp

Trainer B is lv1 and got the exact same vaporeon at 1 cp but he waits with the PU until lv 10 and then do all at the same time , so will the arch be filled by 5 % every power up(so 20 in total) or will he also be able to make the 56 PU too ?

if its everytime 5 % then for trainer B:

1+20*40= 800 cp

i hope its getting more understandable , so the point is will the arch icrease by 5 %

What you’re failing to realize is that, while trainer b is leveling up, the vaporeon’s possible max CP is increasing as well. So, in theory, there is no difference between the way that both vaporeon’s power up.

iv it all comes down to iv. the pokemons iv dictates how much cp/hp is added per level up (power up)

Nice guide how the arch works, thanks.

The way you evolved the Psyduck was a mistake though, even if you knew the CP would be really good, the actual attack the Golduck receive is random, a 1000cp Golduck with Water gun is way better than a 1400 with Confusion. So powering up before you know the evoled versions attacks is a bad move.

I understand what you are saying when you have two of the same poke with close cp. but I believe you left something out. If you look at your Pokemon that you compared there are differences in the size and height. Some being xs and XL and the like. My theory is that the ones you are tossing for having a lower CP potential have something your not considering. Faster attacks in gym battles. My vaporeon attacks super fast and decimates the opponent faster. More hits with lower cp but faster. It is the xs factor that speeds up the attacks.

I also have a strange question.

for example I have 2 pidgey. one has 10 cp the other has 500 CP. Ofcourse the 10 cp pidgey has no curve and the 500 cp has it at max.
Now I level both pidgey’s up untill I get 2 pidgeot. the 10 cp pidgeot should have zero curve and the 500 pidgeot is at max. Now here is the question.

Will pidgeot 0 curve get stronger than pidgeot max curve when I level it with candy untill max???

Here is why I ask. If you level a pidgey it doesnt get much CP while leveling a pideot it gets more cp. So in the long run you will get more CP when you can level up a pidgeot.
Now the 500 pidgey already has max CP and curve. So on his lower evolution it got his level up which is less CP gain than a Pidgeot would have. And therefore the Pidgeot cannot get grow more.

Does this mean that the more candy you use to power up a pokemon, the more times you get higher cp and the higher curve pokemon cannot benefit from the leveling with candy so they are weaker in the end.

There doesn;t seem to be an answer to this on the internet. Am I the only one thinking of this?

If my example is the case you should be rewarded for farming and using a lot of candy/dust to evolve your low cp curve pokemon and then leveling it. If this isn;t the case, than we should all wait untill lvl 30 catch the highest pidgey and evolve it to pidgeot and there is the max pidgeot. no need to worry about candies and dust and just ignore it…or even better…catch a max lvl pidgeot (shich is still less strong than a half curve Snorlax xD

I have one Pidgeot that initally started around 480 CP after I had evolved it back when I was level 8 or something. He was near max CP at the time, so every time I leveled up, I kept powering him up to max. I am now level 16 and he is now 920 CP with 93 HP. He absolutely wrecks the ~1300 CP Vaporeons that run the gyms around here. I am starting to think powered up pokemon get much stronger than high CPs that you find in the wild but are not powered up with star dust, but my sample size is just this one Pidgeot. I’ll continue to max him out and see how he does as others get stronger too, but was just wondering if anyone else has noticed anything like this.

Question here….

Max the pokemon’s CP before evolving or evolve first then max CP?

Beate

Hi! Great guide!

Is CP the only thing that matters? Like one Pokemon can have more CP than another one of same kind, but the other one might have higher level at one of the two attacks. Still go for the one with highest CP?

And again, two of same kind of Pokémon. But they have different attacks. How do I know which attacks to go for?
E.x.:

Pidgeotto 1:
CP: 314,
HP: 58,
12 Wing Attack (Flying),
25 Air Cutter (4) (Flying)

Pidgeotto 2:
CP: 268
HP: 50,
12 Wing Attack (Flying),
15 Twister (5) (Dragon)

In this example Pidgeotto 1 has Flying as attack, and Pidgetto 2 has Dragon. It’s like this with many of my Pokémons and I don’t know which to choose to evolve. Should I compare them with other Pokémons I have? See if there is some other Pokémons which has some kind of same attack, and then evolve / power up the other one?

I try to keep them with moves that match their natural ability. Like the pidgeotto with two flying moves would be stronger than the one with a dragon move as its a flying Pokemon and not dragon! Or am I being daft???

I’m level 15 and have powered up nothing. I jumped from level 10 to 15 by activating a lucky egg and evolving a bunch of rubbish weedles, caterpies, pidgeys and rattatas. I can catch ALOT of them around my way so evolved like 20 pidgeys and 10-12 of the rest. I worry that I’ll waste dust on something and find a stronger one. I had a hunch that if you stuck with one it would be stronger than any you find because your ‘training’ it with the power ups. Power it up and up then evolve it at later time and power again. Like if you powered up your starter from the beginning it would be stronger than anything you could find????

I found a CP 41 cubone when I was level 9. His arch is just under quater full. The HP is 16 has two ground moves (mud slap and bulldoze) and is XL in weight but normal height. Dust to power him at the mo is 200 a pop.

Is he worth levelling? Just sticking with it or would this be a waste????

MrPau1

Apparently he is common anyway? Yet Lickatung is very rare but when I was in Bath UK in Victoria Park my son caught 7 ???? Go figure. I’m glade and hope they don’t put stardust in the items you can buy with pokecoins. Play to win not pay to win. Sadly I fear they may just do it one day and those that have cash to burn will buy dust and candies and it all means nothing then. It’s good game. I hope in future you can trade, battle with other trainers. wish they would sort the darn footstep thing out too. It’s just random luck at the moment.

Hey great information!
I was just wondering why you powered up the psyduck before evolving him? Shouldn’t you power up after evolving just in case he doesn’t get the best moves available? I would really appreciate an answer because I always wondered why some people powered up just before evolving. I am lvl 10 btw.

I only almost have 25 eevee candy at lvl 10… but I mean pidgeots are only so strong, I need at least one 1k+ pokemon before lvl 20. So maybe get a vaporeon. I’ll get back my 25 eevee candy by the time I’m lvl 20+ so I can then get a really good vaporeon. Idk… you’re the pro

I guess you’re right. So lvl 0-20 is grind and then towards level 20 you can finally see the fruit of your work? And how can you use six different pokemons to take down one stronger one?

Hi guys sorry I have a question but I really need some guidance, I caught a 454 cp Venausar and it meets about the halfway mark on the power level thing (I’m level18) and i was wondering if that means it will only reach about 900 cp which definitely means it wouldn’t be worth powering up, thanks for any responses in advance!

I’m also a level 21 and I’ve been trying to decide if I should power up and then evolve or evolve and then power up. What is your opinion on this/ does it even matter at all? I’ve been powering up and then evolving, but I’m still unsure.

Yea I was reading other comments on this thread and you said that when you evolve your Pokemon the max CP bar doesn’t move which leads me to believe it is all just percentage based and it doesn’t matter whether you power up then evolve or evolve then power up. And about saving stardust, I’m going to start doing that. I just got my first gyarados so I got a little carried away with spending stardust. Thanks for the quick reply.

Question, how do you tell what skills are better? Like, if you had two pidgeys and they had the same stats except for the skills. Say, one had quick attack and poison fang and the other had bite and air cutter..who would you transfer?

It’s easy now.

We should check the IV’s of the pokemon (Google it) and then decide what to do…if you have 100% IV then you should evolve it or something 😀

Hi, does it matter if I power up before ou after evolving?

Thank you very much and nice article.
