How to keep your battery in top shape
 If the battery has not been used for a long period of time, you may
not be able to power on your mobile phone immediately after you
begin charging the battery. The icon as shown in the following
figure is displayed on the screen.
 Allow the battery to charge for a few minutes with the phone
powered off. When the charging animotion is displayed on the
screen, power the phone on.
 Using data services increases demand for electrical power and will
hence the stand-by and talk time of the device.
 The time required to charge the battery depends on the ambient
temperature and the age of the battery. We recommend you to
charge at room temperature (20°C–22°C).
 When the battery is low, the phone plays an alert and displays a
message. When the battery power charge is almost drained, your
phone will power off automatically.
 The battery undergoes aging which results in a decrease of the
capacity with time. This will be noticeable by some incremental
reduction of the stand-by and talk time of the device. In order to
revert to the original stand-by and talk time it is recommended to
replace the battery with a new one of the same type.
