15. Battery information
Charging and Discharging
Your phone is powered by a rechargeable battery.
Note that a new battery's full performance is achieved only
after two or three complete charge and discharge cycles!
The battery can be charged and discharged hundreds of
times but it will eventually wear out. When the operating
time (talk-time and standby time) is noticeably shorter
than normal, it is time to buy a new battery.
Use only batteries approved by the phone manufacturer
and recharge your battery only with the chargers approved
by the manufacturer. Unplug the charger when not in use.
Do not leave the battery connected to a charger for longer
than a week, since overcharging may shorten its lifetime.
If left unused a fully charged battery will discharge itself
over time.
Temperature extremes can affect the ability of your battery
to charge.
Use the battery only for its intended purpose.
Never use any charger or battery which is damaged or
worn out.
Do not short-circuit the battery. Accidental short-
circuiting can occur when a metallic object (coin, clip or
pen) causes direct connection of the + and - terminals of
the battery (metal strips on the battery) for example when
you carry a spare battery in your pocket or purse. Short-
circuiting the terminals may damage the battery or the
connecting object.
Leaving the battery in hot or cold places, such as in a
closed car in summer or winter conditions, will reduce the
capacity and lifetime of the battery. Always try to keep the
battery between 15°C and 25°C (59°F and 77°F). A phone
with a hot or cold battery may temporarily not work, even
when the battery is fully charged. Batteries' performance
is particularly limited in temperatures well below freezing.
Do not dispose of batteries in a fire!
Dispose of batteries according to local regulations (e.g.
recycling). Do not dispose as household waste.
