My phone's charging port doesn't charge anymore. I've been using a normal Fast charger block and cable (original Samsung ones) until my phone started taking at least 10 hours for a full charge. That's when I decided to start charging my phone wirelessly (takes 2 hours and 40 minutes for a full charge). Now when I use my friend's charger (ultra fast charging block and USB-C to USB-C cable) it surprisingly charges my phone in one hour (from 0 to 100). I don't really know if the problem is from my cable or from my charging port, because I've noticed something white(looks like a plastic thing that doesn't move at all) that's in my charging port but not in any of my friends' phones who have another phone from the S Series.
Any help/advice is appreciated.
Try a different cable- they don't fast charge anymore if they start to break apart
