• 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).
• 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 bag where the battery may contact
metal objects. 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.
