Megaman 10 confirmed

[Rökkan]

Actually, in classic MM games, I almost never use charged shots. A fully-charged shot's power is equal to three normal shots. BUT, in order to charge it, you have to hold B, and then wait one second +/- so that Megaman can BEGIN charging. And you have to wait more two seconds so that Megaman can charge it all up, and a halfway charged shot's power is STILL of one single shot. So, it's more or less useful to charge your buster before getting into a room, but once you release it and you still have enemies to deal with, shooting with your regular shots is much more useful.
