Charging

■ Internal battery life
• The internal battery is a consumable accessory. Each time it is
charged, time available with each charging reduces.
• Using apps, etc. while charging the internal battery for a long time
may shorten the battery life.
• When a time available with each charging is reduced to about
a half from that of a new battery, replacement of the battery is
recommended because it is near the end of life.
■ Charging
• AC Adapter 07 (sold separately) is applicable to the range of 100
VAC and 240 VAC.
• For details of AC Adapter 07, see respective manuals.
• The AC adapter has a plug dedicated to 100 VAC (for domestic use). When
using the AC adapter in the range of 100 VAC and 240 VAC overseas,
a conversion plug adapter applicable to the country you are staying is
required. Do not charge the battery using a transformer for overseas travel.
• When the terminal is turned ON, you can operate the terminal even
while charging. However, in that case, charging takes longer time
because of reducing charging volume.
• When inserting/removing the connector, make sure not to put
excessive force.
• You can check the latest charger with the terminal in the DOCOMO
online shop.

■ Do not charge for a long while (several days) with the power turned on.
• If the terminal is left for a long time with the power turned on while
charging, the internal battery starts feeding the terminal when the
charging is complete. For that reason, the actual battery time may
shorten and battery alert may appear shortly. In such case, charge
again in a proper way. When charging again, remove the terminal from
the AC adapter, DC adapter and set again.
■ Estimate internal battery operating time
• The operating time of the internal battery varies depending on the
operating environment and the degradation level of the internal battery,
etc. For estimate of operating time, see "Main specifications" (P.152).
■ Estimate internal battery charging time
• For estimate of charging time, see "Main specifications" (P.152).
