Sometimes the charging controller software hangs.
Press and hold the Volume Down and Power (Side) buttons simultaneously for about 10–15 seconds. If the phone has even 1% battery left, it should force a reboot. Try charging again immediately after it vibrates. 2. Inspect the Port (The "Dubai Dust" Check)
Since you are in a sandy/humid environment, it is very common for pocket lint or fine dust to compress inside the USB-C port.
Use a bright light to look inside the charging port. If you see any debris, gently use a wooden toothpick or a plastic SIM tool to clear it out. Avoid metal objects, as they can short the pins. 3. Rule out the Accessories
Since it "degraded" (Super Fast -> Fast -> Dead), it’s possible the cable or brick has a short.
Try a different 45W PPS brick and a 5A cable. If it doesn't respond to a cable, try placing it on a Wireless Charger. If it charges wirelessly: The USB-C port is likely damaged or dirty. If it doesn't charge wirelessly: It might be a deeper motherboard or battery issue. 4. Check for Moisture
Did you get a "Moisture Detected" warning recently? Sometimes that sensor gets stuck.
Try blowing compressed air into the port or letting it sit in a dry area for an hour.
