Charging the Battery
Your phone is powered by a rechargeable standard Li-Ion battery. 
Only use Samsung-approved charging devices and batteries. 
Samsung accessories are designed to maximize battery life. Use 
of other accessories may invalidate your warranty and may cause 
damage. 
Use the Travel Adapter
The travel adapter included 
with your phone is a 
convenient, light-weight 
charger that rapidly charges 
your phone from any 120/220 
VAC outlet. 
1.
Plug the large end of the Travel Adapter into a standard 
120 VAC or 220 VAC wall outlet.
Important!: For connection to an electrical supply not located in North America,
you must use an adaptor of the proper configuration for the power 
outlet. Use of the wrong adapter could damage your phone and void 
your warranty. 
2.
Insert the smaller 
end of the Travel 
Adapter into the 
charger/accessory 
connector on the 
right side of your 
phone. 
Important!: You must unplug the adapter before removing the battery from the
phone during charging to avoid damage.
