Question
Answer
Which are the
factors that
affect the
lifetime of the
battery?
The lifetime of the battery depends on the
number of times that the battery has been
charged, the duration that the battery is
charged each time, and the duration that
the battery has been in service.
The lifetime also depends on the ambient
temperature, internal temperature of the
battery, contact between the battery and
the phone, and signal strength of the
phone.
When there is
an incoming
call, why is the
caller's name
not displayed?
The name and number of the caller is not
stored in your phonebook or the phonebook
is being initialized.
What should I
do when I
power on my
phone and the
phone
requires the
phone code?
The phone has a phone lock function that
is disabled by default. If the phone lock
function is enabled, the phone code is
required when the phone is powered on. By
default, the phone code is 1234.
If your SIM card is locked, unlock it by
entering the PUK delivered with the SIM
card.
If you have lost the PUK, go to the nearest
service store of the network service
provider for assistance.
