Why do fast chargers take so much longer to complete a full charge?

I’ve had several phones with fast charging. They’re amazing. You can charge your phone over 60% in 40 minutes. But why do they slow down so much when it comes to bring a phone to full charge?

Fast chargers are designed for people on the run that rely on an initial charge to give them enough power by the time they are off again to their next destination, an example may be when you are waiting for your flight to be announced so you can run to the gate, or when you need more juice in the time that it takes your discussion to conclude. Another thing is many batteries these days have significantly higher capacity than previously possible, this capacity can take longer to charge overall, you may notice on some devices your quick charge to 30% actually lasts a significant time, as where years back 30% was too critical to get any work done.
