Terminal operation
Phenomenon Cause and handling
Become hot
while operating/
charging
While calling, depending on the
radio wave condition or call
duration time, the terminal may
become hot around the
earpiece/speaker. This condition
is not abnormal.
While operating or charging, or if
you use applications, record
videos, etc. for a long time while
charging the battery, the
terminal, internal battery or
adapter may become hot. It is
not a problem for operation. You
can continue to use the terminal.
When the temperature of the
terminal is raised, a message
appears on the Notification
panel and some applications or
services may become
unavailable.
In this case, wait until the
temperature of the terminal
drops and use again.
The operation
time provided by
the battery is
short
Is the terminal left for a long time
under the state of out of service
area?
Out of service area, a lot of power
is consumed to search available
radio waves. If you are out of
service area for a long time, set
Airplane mode or power off the
terminal.
P.47, P.180
The operating time of the battery
varies depending on the operating
environment and the degradation
level of the internal battery.
P.244
The internal battery is a
consumable part. Each time the
internal battery is recharged, the
battery usage time per one
charge gradually decreases.
If the operation time becomes
too short even in fully charged
state, contact "Repairs (Inquiries/
Request)" on the last page (in
Japanese only) or a DOCOMO-
specified repair office.
Check if multiple applications are
activated.
Exit the unused applications.
P.99
When the Wi-Fi function or
Bluetooth function is not used,
turn off the setting.
P.172 , P.213
When STAMINA mode is set, the
operations and a part of functions of
the terminal are restricted so that the
consumption of the battery power
can be reduced.
