Getting the best out of your battery pack
Use the approved Battery Pack N11 for a FOMA terminal.
■ Battery life
a
Batteries have a limited service life. Like all rechargeable batteries, the amount of usable time
decreases every time the battery is recharged.
a
When a fully charged battery pack only lasts half as long as when it was new, it is time to replace
it with a new one.
a
In general, the service life of a battery pack is about one year. It may be shortened depending on
the frequency of use.
■ Charging
a
For details, refer to the manuals for FOMA AC Adapter 01 (optional) and FOMA DC Adapter 01
(optional).
a
Attach the battery pack to a FOMA terminal to charge the battery.
a
You can receive calls while charging if a FOMA terminal is turned on. However, the battery level
will fall during calls and the time required for charging will increase. Charging time will also
increase if “Charging” in “Backlight” is set to “All time ON”.
a
When plugging in or out the connector, do it slowly and securely not to apply excessive force.
■
Do not charge the battery pack for a long period of time (several days) with a FOMA terminal turned
on.
a
If you charge the battery pack for a long period of time with a FOMA terminal turned 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 period of time and the low voltage
alarm may sound immediately. In this case, recharge the battery pack correctly. Disconnect a
FOMA terminal from the AC adapter (or desktop holder) or DC adapter and then attach it again
for recharging.
■ Battery duration (The battery duration varies depending on the charging time or deterioration of the
battery.)
a
The continuous talk time is an estimated time you can talk while a FOMA terminal can normally
send and receive radio waves.
a
The continuous standby time is an estimated standby time when a folded FOMA terminal can
normally receive radio waves. Note that the actual continuous talk/standby time may decrease
by as much as half depending on the following conditions: the battery level, 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 or use i-mode, creating i-mode mails, starting up downloaded i-
α
ppli
programs and the i-
α
ppli standby screen or playing music will also decrease the talk
(communication) and standby times.
a
The standby time (stationary) is an average standby time when a folded FOMA terminal keeps
still while radio waves can be normally received.
a
The standby time (moving) is an average standby time all including “stationary”, “moving” and
“out of service area” when a FOMA terminal is folded and radio waves can be normally received.
a
Continuous playback time is a reference time when an SD-Audio data of AAC data format and
96kbps bit rate is played when a FOMA terminal is folded, the attached stereo earphone
(sample) is used and the playback volume level is set to 14.
a
Inserting the miniSD memory card, performing data communication or multi access or using the
camera or 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.
Continuous talk time Continuous standby time Continuous playback time
Voice call: Approx. 150 min.
Videophone call: Approx. 100 min.
Stationary: Approx. 560 hours
Moving: Approx. 440 hours
Approx. 540 min.
NOTE
e
If the battery pack is out of charge or removed, you cannot save images or movies.
