your SIM card is loaded with your subscription details, 
such as your Personal Identification Number (PIN), 
available optional services, and other features.
Warning: Please be careful when handling the SIM card 
to avoid damaging it. Keep all SIM cards out of reach of 
small children.
You can also install an optional microSD
™, microSDHC™, 
or microSDXC™ memory card (not included) to add more 
memory space to your device. A memory card can be 
installed at any time. It is not necessary to install it 
prior to using the device. Note

instructions are for reference only.

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, refer to “Maintaining Water and Dust 
Resistance” on page  255.
Charge the Battery
Note: You should dry the inside of the charging port 
before inserting a power connector to charge your 
device. If the charging port is not fully dry, your device 
may operate abnormally. For example, it may charge 
more slowly or overheat. For more information, refer to 
“Maintaining Water and Dust Resistance” on page  255. 
Your device is powered by a rechargeable, standard 
Li-Ion battery. A USB charger (charging head and USB 
cable) is included with the device for charging the 
battery from any standard outlet.
The battery comes partially charged. You can use the 
device while charging.
Note : For fastest charging times, use the Adaptive 
Fast Charger that came with your device. This charger 
provides faster charging only when connected to 
devices that support Adaptive Fast Charging.

1. Insert the USB cable into the USB charger/
Accessory port.
Caution: Use only charging devices and batteries 
approved by Samsung. Samsung accessories are 
designed for your device to maximize battery life. Using 
other accessories may invalidate your warranty and 
may cause damage.
2. Connect the USB cable to the charging head, and 
then plug the charging head into a standard outlet.
3. Unplug the charging head from the outlet and 
remove the USB cable from the device when 
charging is complete.

When to Charge the Battery
When the battery is low and only a few minutes of 
operation remain, the device sounds a warning tone at 
regular intervals.
In this condition, your device conserves its remaining 
battery power by dimming the screen.
When the battery level becomes too low, the device 
automatically turns off.
For a quick check of your battery level:
 ► View the battery charge indicator located in the top 
right corner of your device’s display. A solid color  
( 
 ) indicates a full charge.  
						

							Set Up Your Device11
You can also choose to display a percentage value. 
Viewing a percentage value can provide a better idea 
of the remaining charge on the battery. For more 
information, see “Battery” on page  209.
While charging, the device and the charger may 
become hot when using 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. 
The charger may stop charging if the battery becomes 
too hot. If the device heats up while charging the battery:
1. Disconnect the charger from the device and close 
any running apps.
2. Wait for the device to cool down, and then begin 
charging the device again.
• If the lower part of the device overheats, 
check for damage to the connected USB cable. 
Replace the damaged USB cable with a new 
Samsung-approved cable.
If using a wireless charger, do not place foreign 
materials between the device and the wireless charger.
Micro-USB Connector
You can use the included Micro-USB connector to 
connect a Micro-USB cable (such as from your old 
device) to your new device for charging with the 
charging head, or for connecting to a computer.

Note: The Micro-USB connector does not support 
On-the-Go (OTG) devices such as memory sticks, 
external hard drives, or keyboard and mouse 
accessories.
