I was curious so I decided to try the on/off method just now. I only did for 10mins but must say that it can work with practise.
Anyway in 10 mins I managed to do 27-28 evolves. This equals to 84 evolves in 30mins. Not so good but already better than my best of 76 using normal method. I was quite kelam-kabut. Will take some practise to perfect the sequence: evolve, switch to app switcher, quit app, start app, tap ok, go to pokemon list, scroll, press evolve and repeat. I'm using iPhone 6s so speed is quite fast. Didn't encounter any probs with PoGo signing in multiple times in the 10 mins.
Probably for my next mass evolve, I'm going to try this.
A few things I noted:
- I double checked that the XP from the evolves are registered. Was afraid with all the quitting and restarting, some XP may have been missed. But no, it's all there.
- I believe you can quit PoGo as soon as you press Yes to evolve. The server seems to register the evolve as soon as you press Yes. But internet connectivity quality may affect this.
- There's no level up animation. During my test, I went from Level 24 to 25 after one of the evolves. The level up animation does not play after restarting PoGo. But I confirm that the level rewards are received.
- I'm on an iPhone and double pressing the Home button is one way to bring up the app switcher to quit PoGo. An alternative is to use AssistiveTouch. 2 taps to bring up the app switcher. Not sure which is faster but the latter will be less destructive to your home button.
- I did my test on 4G but wifi should work equally well.
- The "Sort By..." remains after app restart but the scroll position is reset to the top
- You can Fav as usual but you can't un-fav since un-Fav only works after the evolve PoGo needs to be restarted as soon as you press Yes to evolve so some scrolling will be needed which will eat up some time.
- I might consider not using Fav for this because the secondary sort for Fav'ed Pokemons is CP. It's going to be one big mess.
I did a test run with this kill app method,. Cause i proceed without any practice, i only able to get 94 evolve in the 30 minutes.
Yes, i kill the apps immediately after i press yes evolve without loading the animation.
BTW bro, a tips for you,. we can still FAV those evolve pokemon like usual,, just that instead of un-fav them after we evolved,
we can un-fav it before we click yes to evolve it. That way it won't be messy after we kill the apps and restart
