Wireless charging
The device has a built-in wireless charging coil. You can charge the battery using a wireless
charger (sold separately).
Place the centre of the device's back on the centre of the wireless charger to charge the
battery. After fully charging, disconnect the device from the wireless charger.
The estimated charging time will appear on the notification panel. The actual charging time
may vary depending on the charging conditions.
Precautions for wireless charging
• Do not place the device on the wireless charger with a credit card or radio-frequency
identification (RFID) card (such as a transportation card or a key card) placed between
the back of the device and the device cover.
• Do not place the device on the wireless charger when conductive materials, such as
metal objects and magnets, are placed between the device and the wireless charger.
The device may not charge properly or may overheat, or the device and the cards may
be damaged.
• If you use the wireless charger in areas with weak network signals, you may lose
network reception.
• Use Samsung-approved wireless chargers. If you use other wireless chargers, the
battery may not charge properly.
