SAR tests are conducted using standard operating 
positions with the phone transmitting at its highest 
certified power level in all tested frequency bands. 
Although the SAR is determined at the highest 
certified power level, the actual SAR level of the 
phone while operating can be well below the 
maximum value. This is because the phone is 
designed to operate at multiple power levels so as 
to use only the power required to reach the 
network. In general, the closer you are to a base 
station, the lower the power output of the phone. 
Precautions When Using Batteries
• 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.
• 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.
• 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 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.
• Dispose of used batteries in accordance with local 
regulations. Always recycle. Do not dispose of 
batteries in a fire.
