Discharging the Battery
A battery lasts longer and performs better if you fully
discharge it from time to time. To discharge the battery,
leave your phone switched on until the battery is drained
and the phone turns itself off. Then wait for 30 minutes
before connecting to a charging source. (See “Deep
Discharge” on page 9.)
Note: Do not discharge the battery by any other means.

Battery Low Warning
You get this message and a warning
tone when the battery charge is low
and only a few minutes of talk time
remain.
The repetition rate of the battery-low
warnings depends on the remaining battery capacity and
the battery condition. The warnings are more frequent
when you’re in a call.
Note: If you’ve selected the Vibra Only or Silent Ringing
Option, you won’t hear any warning tones. See “Ringing
Options (Menu 3 1)” on page 37.
When the battery charge is too low for the phone to work,
the phone displays
RECHARGE BATTERY
, then beeps,
then shuts itself off.
Charge the battery as described earlier in this section.
Deep Discharge
If you regularly just ‘top up’ the charge in your battery
without ever allowing it to fully discharge first, its life will be
shortened. In order to get the maximum life from your
battery you should allow it to discharge completely about
once a month.
To discharge the battery completely:
1
Leave the phone switched on until
RECHARGE
BATTERY
appears, then let the phone switch off
automatically.
2 Leave the phone alone for about 30 minutes (and do
not connect a charger within this time) after it
switches itself off.

During this 30 minutes, the phone is in ‘Deep
Discharge’ mode. The way to ‘wake up’ the phone is
to connect it to a charger.
3 Fully charge the battery after Deep Discharge.
The phone may remind you to discharge the battery, by
presenting a series of battery-advice messages. Press
