Do you have an official Samsung charger?

Some chargers that aren't provided by Samsung may not charge the device correctly. They might not provide enough amperage to charge the device, or too much therefore affecting the battery.

Incompatible chargers can be harmful to the battery and may short out in extreme circumstances.


The correct amperage for your device can be found in the device's manual and the amperage of a charger can normally be found on the plug.
