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 network

operator.

• 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 source when

it is not in use. 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 because the capacity and lifetime

of the battery will be reduced. Try to keep

the battery at room temperature. A

phone with a hot or cold battery may not

work temporarily, even when the battery

is fully charged.

Li-ion batteries are particularly affected

by temperatures below 0°C (32°F) and

above 60°C (140°F).

• Do not short-circuit the battery.

Accidental short-circuiting can occur when

a metallic object like a coin, clip or pen

causes a direct connection between the +

and – terminals of the battery (metal

strips on the battery). For example, do

not carry a spare battery in a pocket or
