Life of the internal battery
The internal battery is a consumable part.
・
Each time the internal battery is recharged,
the battery usage time per one charge
gradually decreases.
When the battery usage time per one charge
・
becomes about half of that at the time of
purchased, replacing the internal battery is
recommended because the internal battery is
near the end of life.
Watching 1Seg etc. for a long time while
・
charging may shorten the lifetime of the
internal battery.

Before charging
It is recommended to use the AC Adapter 04/
・
05 (optional) for charging. For details on the
AC Adapter 04/05, see the AC Adapter 04/05
manual.
The AC Adapter 03/04/05 is compatible with
・
100V to 240V AC. For using the terminal
overseas, a plug adapter that fits the electrical
outlets in the country you stay is needed. Do
not use an electrical transformer for overseas
use to charge the terminal.
Use a compatible AC adapter or microUSB
・
cable for charging. If you use a charger other
than compatible ones, charging may not be
available or operations may not be performed
correctly.
Insert and remove the AC adapter cable or
・
microUSB cable slowly and evenly so that
excessive force is not applied.
When charging starts, notification LED of the
・
terminal turns on (P.46).
To check the battery level, see the status bar at
・
the top of the screen or from the Home
u
screen, tap
[Settings]
[Status] to see "Battery level".
If you start charging with the terminal
・
powered off, the power turns on, although
you cannot operate the terminal. Therefore,
do not charge the battery in a place where
the use of the terminal is prohibited.
