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 a 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
service provider.
• Battery charging time depends on the remaining
battery charge, the type of battery, and the charger
used. The battery can be charged and discharged
hundreds of times, but it will gradually wear out.
When the operation 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. Disconnect the charger from the power
1. The SAR limit for mobile phones used by the public is 2.0
watts/kilogram (W/kg) averaged over ten grams of body
tissue. The limit incorporates a substantial margin of safety to
give additional protection for the public and to account for any
variations in measurements. The SAR values may vary,
depending on national reporting requirements and the
network band.
