How do you dodge only charge attacks?

The fabled "yellow flash" doesn't really show on my phone that well, I also keep the brightness down for battery reasons.

I dodge charge attacks by watching the defender and waiting for it's telltale pause and different animation that signals the charge move. If the text appears on time you can use that too. After you know it's coming watching the animation will tell you when to dodge, I've learned the common defender charge moves and can dodge at the right time. If it's new I spam dodge to see when it should have hit so I can dodge it the next time properly. I focus more on attacker health than killing the defender on time. Only Pokemon that would change this strategy for me are Blissey and possibly a high Snorlax.

Just focus on defender attacks instead of maxing DPS, time shouldn't be an issue in most every case if you counter pick correctly. Dodging properly is key to this game, whether you dodge every attack or just charge attacks.

There is a rhythm of the pokemon attacking. I personally never used the flash animation. But if the pokemon suddenly got a brief pause without you moving y9ur pokemon around, then it would mean the charge attack is coming, but that pause is so brief (less than a second) that it is very hard to catch if one isn't familiar with it.

The other method is to observe the attack of the pokemon and take guesses whether it is a pokemon with one single big charge bar, or with three smaller bars to be charged. Watch your own bar while attacking with quick moves. If yours filled up to max, then so as your enemy's. If yours are filled one-third, then so as your enemy's one.

Third, if your enemy's charge move is a fast one such as twister and dragon claw, they are more willing to use it rather than one that is slow such as dig, hyper beam, solar beam and moonblast. By that, if you know the possible charge moves of the pokemon you are facing. Take an example, if you filled up a charge bar twice and used your pokemon's charge move once on your own pokemon, and you are facing an Exegguter as an enemy, then you would better off be careful for a deadly solar beam blow.
