and the parameters set by the network operator.

charge and the type of battery and charger used. The
battery can be charged and discharged hundreds of
times, but it will gradually wear out. When the operation
time (talk time and standby 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. When charging after complete discharge, the
phone will not display anything for about 30 minutes.
 Use only approved chargers. When a charger is not in
use, disconnect it from the power source. Do not leave
the battery connected to a charger for more than a week,
since overcharging may shorten the battery life.
 Extreme temperatures will affect the charging capacity of
