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 8.7.4 Display Settings, page 70.
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 3.2 Switch the Handset On and Off, page 13.
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.
