S4 galaxy charging issue.
Hi there not entirely sure if my charging port on my ph got a tiny bit wet or not but it doesn't seem to be charging on the wall plug only on my computer but.. My computer isn't picking up my ph?? The other day it wouldn't charge past 30% the next wouldn't past 50% and is now currently sitting on 70% the charging is so slow it's not funny and when it is off charge and put on idle overnight it loses 10% and not even in use? I'm not sure wether I get a new charger? Usb? Battery? I've checked pins on both items and all looks fine?
Any suggestions plz would really appreciate the help absolutely guttered I can't use my ph as I usually would is now always on idle only used if I'm rung or txtd
