Galaxy S8 is not fast charging when screen is on

Chris Chavez from Phandroid said that Galaxy S8 can’t fast charge while you’re using it. He tested out by turning the screen off while charging, it took only 1 hours and 37 minutes to go from 0 to 100 percent. While the screen was kept on, the charging time went up to nearly 2 hours 51 minutes despite the device still giving the usual fast charging notification.

We assume Samsung adopted this limitation in order to prevent the device from overheating because fast charging tends to heat up phone more than regular charging.

If you want to take full advantage of the S8’s Fast Charging speeds, plug it in and leave it alone. It’s clear that fast charging works best when they are left sitting idle.
