Recommendations on how to save energy:
•
Do not charge a battery when the ambient room temperature is above +40°
C or below
•
+5° C (above 104° F or below 41° F). Charging below +5° C will harm the
battery and shorten the lifetime.
•
Note that storing Li-Polymer batteries at high temperature dramatically
reduces its capacity. For example storage around maximum temperature
reduces capacity with 20% in less than a month, permanently.
•
When extended battery lifetime is needed, set the handset screen saver to
the "Black also in call" option. See Screen Saver on page 62.
•
The battery lifetime and the speech time are highly dependant on which
power save mode that is used. It is recommended that U-APSD is used to
achieve optimal battery lifetime. Other parameters that can affect the power
consumption are Beacon period and DTIM. Location in the system will also
affect the speech time. For more details, see the document System Planning.
•
The handset can be configured to switch off when placed in the charger.
When removed from the charger the handset switches on automatically. See
Switch the handset off on page 67.
•
If the charger will not be used for a longer period of time, remove the power
adapter to the charger.
•
Do not put the handset in charger if no charging is needed.
