If the temperature of your environment is too high or too low, the device’s safeguard may slow down the charging speed.

We recommend charging your device at room temperature for fast, stable charging.

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

- If there is any foreign object stuck inside the USB port or the 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 the charger, the charging may be slowed. Remove the foreign object and try charging again.

- If there is any moisture detected inside the USB port or the 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 charger from your device. Charging with moisture can lead to USB port corrosion and damage to the device. If the USB port corrodes, visit your nearest service center for device repair.

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

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

The device may overheat if you started charging without closing certain apps. If you think the device is overheating, close all running apps and unplug the charger. Resume charging once the device has cooled down.

If the USB cable or the device’s USB port is damaged, it may overheat.

Replace it with a new, authentic cable or visit a service center to have it repaired.

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

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 to protect the device.

Try charging in a cooler environment.
