AVAILABILITY OF VARIOUS FEATURES/RINGTONES
Many services and features are network dependent and may require 
additional subscription and/or usage charges. Not all features are available 
for purchase or use in all areas. Downloadable Ring Tones may be available 
at an additional cost. Other conditions and restrictions may apply. See your 
service provider for additional information. 
BATTERY STANDBY AND TALK TIME
Standby and talk times will vary depending on phone usage patterns and 
conditions. Battery power consumption depends on factors such as network 
configuration, signal strength, operating temperature, features selected, 
frequency of calls, and voice, data, and other application usage patterns. 
BATTERY PRECAUTIONS
• Avoid dropping the cell phone. Dropping it, especially on a hard
surface, can potentially cause damage to the phone and battery. If you 
suspect damage to the phone or battery, take it to a service center for 
inspection. 
	 •	 Never use any charger or battery that is damaged in any way. 
	 •	 Use the battery only for its intended purpose. 
	 •	 	If you use the phone near the network’s base station, it uses less power; 
talk and standby time are greatly affected by the signal strength on the 
cellular network and the parameters set by the network operator. 
• Follow battery usage, storage, and charging guidelines found in the
user’s guide.
• Battery charging time depends on the remaining battery charge and
the type of battery and charger used. The battery can be charged and 
discharged hundreds of times, but it will gradually wear out. When the 
operation time (talk time and standby time) is noticeably shorter than 
normal, it is time to buy a new battery. 
	 •	 If left unused, a fully charged battery will discharge itself over time. 
	 •	 	Use only Samsung-approved batteries and recharge your battery 
only with Samsung-approved chargers. When a charger is not in 
use, disconnect it from the power source. Do not leave the battery 
connected to a charger for more than a week, since overcharging may 
shorten its life. 
• Do not use incompatible cell phone batteries and chargers. Some
Web sites and second-hand dealers, not associated with reputable 
manufacturers and carriers, might be selling incompatible or even 
counterfeit batteries and chargers. Consumers should purchase 
manufacturer or carrier recommended products and accessories. If 
unsure about whether a replacement battery or charger is compatible, 
contact the manufacturer of the battery or charger. 
• Extreme temperatures will affect the charging capacity of your battery: it
may require cooling or warming first.
• Do not leave the battery in hot or cold places, such as in a car in summer
or winter conditions, as you will reduce the capacity and lifetime of the 
battery. Always try to keep the battery at room temperature. A phone 
with a hot or cold battery may temporarily not work, even when the 
battery is fully charged. Li-ion batteries are particularly affected by 
temperatures below 0° C (32° F). 
• Do not place the phone in areas that may get very hot, such as on or
near a cooking surface, cooking appliance, iron, or radiator.
• Do not get your phone or battery wet. Even though they will dry and
appear to operate normally, the circuitry could slowly corrode and pose 
a	safety	hazard.	
• Do not short-circuit the battery. Accidental short-circuiting can occur
when a metallic object (coin, clip or pen) causes a direct connection 
between the + and - terminals of the battery (metal strips on the 
battery), for example when you carry a spare battery in a pocket or bag. 
Short-circuiting the terminals may damage the battery or the object 
causing the short-circuiting.
