When the device heats up while charging the battery

While charging, the device and the charger may become hot especially during wireless charging or fast charging.

This does not affect the device’s lifespan or performance and is in the device’s normal range of operation. If the battery becomes too hot, the charger may stop charging.

Please note:
• Disconnect the charger and close any running apps when the device is overheated. Wait for the device to cool down and then begin charging again
• If the lower part of the device overheats, it could be due to damage connected USB cable. Replace the damaged USB cable with a new Samsung-approved cable
• When using a wireless charger, do not place foreign materials, such as metal objects, magnets, and magnetic stripe cards, between the device and the wireless charger
