Usually to charge up most modern smartphones either an usb cable or mains charger is required. The plug from this kind of cable connects directly into the cell phone charging port found at the very bottom. The gold metal pins transfer the electrical energy to the internal battery pack. If you notice problems that your cell phone can't recognize the charger plugged, then you might need to clean the charging port on your mobile phone. This is because sometimes dust and dirt can block the electrical contact and cause disruption from everyday use in your pocket. This is particularly common on the iphone 4, 5, ipad, ipod, samsung galaxy s3 and mackbook pro devices as well. This guide is fully compatible with most electrical devices, generally the cleaning process is the same for all.
1) Power off the device you want to perform the clean on.
2) Get a cotton bud and pour some rubbing alcohol cleaning solution onto the tip end.
3) Push the wet tip into the charging port and run it over the gold contact pins upwards and downwards starting from the bottom side first gradually working your way up.
4) Then get a small flat head screwdriver and scrape of any excess remains of dirt.

5) Reconnect the device to charger to see if it has fixed the issue. If not it could be the battery itself, the cable or a fault on the PCB.
