Following a report from Phandroid, there is a trick on how you can quickly charge your Galaxy S8 device. They discovered that even though the device says that it’s in the Fast Charging mode, it still takes 3 hours to fully charge. After that, they decided to discover the Samsung’s little secret. By just simply turning off the screen when it shows that it’s in the Fast Charging mode, the device is getting charged by 97 minutes fully.
Many devices that were shipped with this kind of feature, have also the same problem. The Galaxy S8 is one among them.
So, if you ever feel that you are in a hurry and want to charge your phone as soon as possible, the Fast Charging mode will only be efficient if you only turn the screen off while charging.
