11.1.4 Energy Efficiency
Recommendations on how to save energy and battery lifetime:
• Do not charge a battery when the ambient room temperature is above 45°C or below 0°C (above
113°F or below 32°F). Charging below 0°C harms the battery and shortens 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. Refer to the
• The handset can be configured to switch off when placed in the charger. When removed from
