My SCH-a930 won't charge. I still have battery life, and the phone works fine, but the phone won't charge. I have tried multiple wall outlets. Does anyone know how to fix this? Thanks!

Hi,
Please, try using another charger with the phone.
If the problem continues, get a screw driver, unscrew the phone and bring the charging port out. The charging port is at the tail end of the phone.
Clean the surface of the panel where the charging port contact the panel with a spirit and allow it to dry for 30 minute. Couple back the phone and i am sure the charging phone will work fine.
Regards

Try using rubbing alcohol to clean the battery or where the charger goes in the phone. If you have a car charger then try using it. If that works and the wall charger still don't then it is probably the charger and needs to be replaced. The phone may have a short in it for where the charger goes. Or it could be the battery. But if the battery is charged or still holding charge it more than likely is the charger itself or a short in the phone.
