• In some situations, such as during
operation or when charging the battery,
or when watching 1Seg for long periods
while charging, the terminal, internal
battery and/or adapter might become
warm. However, this does not adversely
affect operation, and you can continue to
use the terminal (

P.26, P.28).
Usable time of
the battery is
short
• Check if the terminal is left out of service
area for a long time.
While being out of service area, the
terminal consumes more power to search
for radio wave to establish
communication (
Z
P.265).
• The usable time of the internal battery
differs depending on the usage
environment and degree of deterioration
(
Z
P.265).
• The internal battery is a consumable
item. Usable time per charge gradually
decreases with repeated charging. When
its usable time is extremely short
compared with that at the time of
purchase, contact "Repairs" (
Z
P.295)
or a repair counter specified by
DOCOMO.
