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 that is damaged.
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. Battery 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.
Remove the battery only when the phone is switched off.
