Getting the best out of your battery pack
Use the specified Battery Pack N13 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.
To protect the environment, take used battery packs to NTT DoCoMo, the agency, the recycle
shop, etc.
■ Battery pack charging
・For details, refer to the manuals for the FOMA AC Adapter 01 (optional) and FOMA DC Adapter 01 (optional).
・When charging the battery pack, 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 of time with the 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 time and the low-voltage 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,
then set it again for recharging.
■ Battery usage time (The battery duration varies depending on the charging time and the deterioration of the
battery.)
・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-αppli, i-αppli standby screen will also decrease the talk (communication)
and standby times.
・The continuous 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 continuous 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.
・Performing data communication or multi access or using the camera or the light will also shorten the talk
(communication) and standby times.
