Getting the best out of your battery pack
To maintain full performance of the FOMA terminal, use the specified Battery Pack N09 for the FOMA
terminal.
■
Battery life
・
Batteries have a limited service life. Like all rechargeable batteries, the amount of usable time
decreases every time the battery is recharged.
・
When a fully charged battery pack only lasts half as long as it did when new, it is time to replace it with a
new one.
・
In general, the service life of a battery pack is about one year. Note that it may be shortened depending
on the frequency of use.
■
Battery pack charging
・
For details, refer to the manuals for the FOMA AC Adapter 01 (optional) and FOMA DC Adapter 01 (optional).
・
To charge the battery pack using the AC adapter or DC adapter, the battery pack must be attached to
the FOMA terminal.
・
You can receive calls during charging if the FOMA terminal is turned on. However, the battery level will
fall during the call and the time required for charging will increase. Charging time will also increase if the
“Display light” for “Charging” is set to “All time ON”.
・
When plugging in or out the connector, do it slowly and securely not to apply an excessive force.
■
Do not charge the battery pack for a long period of time (several days) with the FOMA terminal
turned on.
If you charge the battery pack for a long period with the FOMA terminal switched on, power to the
FOMA terminal will be supplied from the battery pack once charging ends. As a result, you will only
be able to use the FOMA terminal for a short time and the low-battery alarm may sound
immediately. In this case, recharge the battery pack correctly. Disconnect the FOMA terminal from
the AC adapter (or desktop holder) or DC adapter and then set it again for recharging.
・
The continuous talk time is an estimated time you can talk while radio waves are strong enough to send
and receive.
・
The continuous standby time is an estimated time when radio waves are strong enough to receive
properly with the FOMA terminal folded. Note that the actual continuous talk/standby time may
decrease by as much as half depending on the following conditions: the battery level, the function
settings, ambient environment such as temperature, the status of radio waves (out of service area or
weak radio waves). Using i-mode will decrease the talk (communication) and standby times. Even
when you do not talk on the phone or use i-mode, creating i-mode mail or starting up downloaded
i-
α
ppli and i-
α
ppli standby screen will also decrease the talk (communication) and standby times.
・
Using alarm tone or vibrator frequently for “Alarm clock” or “Notify cost limit” function shortens the talk
and standby times.
・
The standby time in stationary is the average usage time when the FOMA terminal is folded and
standing still while radio waves can be normally received.
・
The standby time in moving is the average usage time when the FOMA terminal is folded under condition of
“stationary”, “moving”, and “out of service area” within the area where radio waves can be normally received.
・
Loading the miniSD memory card, performing data communication or multi access or using the camera
or the light will also shorten the talk (communication) and standby times.
To protect the environment, take used battery packs to NTT DoCoMo, the agency, the recycle shop, etc.
Battery usage time
(The battery duration varies depending on the charging time and the
deterioration of the battery.)
Continuous talk time
Continuous standby time
Voice call: Approx. 130 min.
Videophone call: Approx. 80 min.
Stationary: Approx. 430 hours
Moving: Approx. 350 hours
NOTE
●
If the battery pack is out of charge or you have removed the battery pack, you may be unable to save images or movies.
