Nokia X1–01 User Manual page 29

Up to 14 hours.
Standby:
Up to 1118 hours.
Important: Battery talk and
stand-by times are estimates and only
possible under optimal network
conditions. Actual battery talk and
standby times depend on SIM cards,
features used, battery age and
condition, temperatures to which
battery is exposed, network
conditions, and many other factors,
and may be significantly shorter than
those specified above. Ringing tones,
hands free call handling, use in digital
mode, and other features will also
consume the battery, and the amount
of time a device is used for calls will
affect its stand-by time. Likewise, the
amount of time that the device is
turned on and in the standby mode
will affect its talk time.
