Getting started
NOTE Use only charging devices and batteries (if applicable) that are approved
by Samsung. Samsung charging devices and batteries are designed for your
device to maximize battery life. Using other charging devices and batteries may
void your warranty and may cause damage.
NOTE Your device is IP68 rated for dust and water resistance. To maintain the
water-resistant and dust-resistant features of your device, make sure that the
SIM card/Memory card tray openings are maintained free of dust and water, and
the tray is securely inserted prior to any exposure to liquids. For more
information, see
Charge the battery
Your device is powered by a rechargeable battery. A charger (charging head and USB
Type-C cable) is included with the device for charging the battery from a power
outlet.
TIP While charging, the device and the charger may become hot and stop
charging. This usually does not affect the device's lifespan or performance and is
in the device's normal range of operation. Disconnect the charger from the device
and wait for the device to cool down. For more information, visit
