※ You cannot fast charge your phone using a regular power adaptor.
※ If fast wireless charging is not working, check your settings as listed above and make sure you are using a fast power adaptor.

If the temperature in your environment is too high or too low, the device’s safeguard could slow down its charging.

For stable, fast charging, we recommend charging at room temperature.

If you are charging with a power cable connected to a computer, the voltage will be less than that of a power adaptor, resulting in a slow charge. For the best results, we recommend using a power adaptor.

- If there is a foreign object stuck inside the charger port or power cable, the device's safeguard may shut off charging for its protection. With a soft brush, remove the foreign object and try charging again.

- For wireless charging, if there is a foreign object located between the device and power adaptor, the charging may be slowed. Remove the foreign object and try charging again.

- If there is any moisture detected inside the charger port or power cable, the device's safeguard will notify you that moisture is detected and will shut off charging.

Try again after the moisture is removed.

※ If moisture is detected (water drop icon), unplug the power adaptor from your device. Charging with moisture can lead to charging port corrosion and damage to the device. If the charging port corrodes, visit your nearest Samsung Service Centre for device repair.

Charging may be slowed if power cable is not properly connected to the device or power adaptor, if the connector pin is altered due to long periods of use, or if the surface is corroded due to foreign objects.

If charging continues in this state, the device may be damaged or may overheat. We recommend visiting your local Samsung Service Centre for advice.

The device may overheat if charging is started while certain apps are still running. If you believe the device is overheating, close all running apps and disconnect the power adaptor. Resume charging once the device has cooled down.

If the power cable or the device's charging port is damaged, it may overheat.

Replace it with a new, power cable or visit a Samsung Service Centre to have it repaired.

- Check for any foreign metallic or magnetic objects located between the device and the power adaptor, remove the object and separate the device from the power adaptor.

- Resume charging once the device has cooled down.

- If the device is charged with its case on, it may overheat due to confined space. Resume charging after removing the case.

If charged in a hot environment, such as inside a car on a hot summer day, charging may stop protecting the device.

Try charging in a cooler environment.
