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.
To check the charging performance, from the

Before charging
It is recommended to use the AC Adapter 05
･
(optional) for charging. For details on the AC
Adapter 05, refer to the AC Adapter 05
manual.
The AC Adapter 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.45).
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.
