Most of the time, that’s the only thing you need to do to make your phone fast charge again. However, after making sure the fast charging feature is enabled and your galaxy s20 is still not fast charging, there are a couple of things you need to do. 

Turn off your phone and charge – this isn’t a solution but we need to know if your phone is still capable of fast charging. So power it down and charge it. If it actually fully charges after an hour from 10% and below, then it’s fast charging

Reset your phone – a reset might be able to fix a charging issue that’s caused by a firmware problem. However, make sure to backup your important files and data prior to the reset as they will be deleted. When ready, follow one of our guides below on how to reset your galaxy s20.

If the problem persists after doing all those things, then have the phone checked by a technician as the issue can be with the hardware.
