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.
z
Extreme temperatures will affect the charging capacity of your battery: it may require
cooling or warming first.
z
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).
z
Use only approved batteries and 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 lift.
