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?

What you’re experiencing is called the Stadium Effect.
The stadium effect occurs when recharging your batteries. You’ll notice your battery quickly filling up in the beginning, then slowing down noticeably when trying to charge up the last several percentages.
Think of how quickly a stadium fills up when the doors first open- there are hundreds of open seats so it’s easy to find the one you want. Eventually there are only a few open seats here and there and people have to maneuver around to find a spot and filling those seats takes longer.
The same theory applies to recharging batteries. It’s easy for energy to flow in and take up empty space in the beginning, and as time goes on and there is less space available, it takes longer for the energy to find and fill in those holes.
