Operation Manual

21
You can charge the battery both with the
phone switched on and switched off.
It takes approx. 4 hours to fully charge an
empty battery.
4.2 Operating time
A fully charged battery kept in a good state
offers a standby time of up to 350 hours
and a call time of up to 3 hours. When this
time shortens considerably, it’s time to re-
place the battery.
The operating time depends on the provid-
er (when far away from the radio tower, the
phone consumes more transmission pow-
er) and on the use of the phone (ring vol-
ume, vibration function enabled or disabled,
duration of display illumination, etc.)
If the operation time of the phone shortens
considerably while being used as normal,
it’s time to charge the battery.
