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.
Allow it to cool down or warm up first.
