Begin by checking your charging cable to see if it works with another device, or trying another charging cable in the same device.
Make sure to also check the charging port on your phone. It may be blocked with lint buildup or other debris. If there is lint present, carefully remove it using a can of compressed air.
If your charging port is clear, but you continue to have issues charging your phone, make sure software is up to date. To do this, you should go to Apps > Settings > More > System Update > Update Samsung Software.
Finally, you can try to fully restore your device. To do this, backup the data on your phone and erase all content and settings. Read our instructions on backing up your device here. Learn how to reset your content and settings here.
