and there are other similar charging problems i get to understand that are stemmed from this problem
so if u have any charging problems i suggest u try it before u send it off to the repair shop and spend unnecessary money
first thing you should always do is to try another charger or usb cable... preferable one that has a real tight fit
ok now to the solution.. incase you didnt know when you carry around your phone in your pocket some loose fabric gets into the charging port which causes alot of issues.
it can cause:
pc non recognition problems
no charging at all
etc. basically anything that has to do with the charging port
all u need to do is get like a needle or a small pin or something of that nature and clean out that fabric out of the port... and if possible blow it out after to make sure that any loose fabric the needle or pin loosened is removed
be careful when doing this ! dont jam down in to it..just gently move it around in there and try not to damage anything. TAKE EXTREME CARE. BE WARNED.
