good for over 2-4 hours of calling time, whilst standby
time usually lasts from 24-72 hours.
Prior to removing the battery, make sure the phone is
switched off and not connected to a battery charger.
Under no circumstance use a charger or battery that is
damaged in any way.
When using the phone in the vicinity of a base-station
of a network, power usage will decrease. The battery
time in which a device can remain in standby mode or
be operational for calling is strongly affected by the
strength of the signal of the mobile network.
Charging time depends on the remaining battery
power, the type of battery and the charger used for
charging the battery. A battery may be charged and
discharged hundreds of time, but it will become worn
out over time. Obtain a new battery as soon as you
notice a decrease in standby or calling times.
Unplug the charger when it is not being used. Do not
leave the smartphone attached to the charger for a
period exceeding 48 hours straight. Overcharging may
drastically decrease battery life. Even when unused, a
fully charged battery will slowly get depleted.
Make sure both the positive battery pole (+) as well as
the negative battery pole (-) connect with the contacts
in the smartphone when installing the battery.
