When the battery is running out of power and your phone only has a few
minutes of talk time remaining, a warning tone sounds and the Battery
low message appears briefly. When no more talk time is left, a warning
tone sounds and the phone switches itself off.
Do not short-circuit the battery. Accidental short-circuiting can occur
when a metallic object (coin, clip, and pen) causes a direct connection of
the + and - terminals of the battery (metal strips on the battery), for
example, when you carry a spare battery in your pocket or purse. Short-
circuiting the terminals may damage the battery or the connecting object.
Leaving the battery in hot or cold places, such as in a closed car in either
summer or winter conditions, will reduce the capacity and lifetime of the
battery. Always try to keep the battery between 15°C and 25°C (59°F
and 77°F).
A phone with a hot or cold battery may temporarily not work, even when
the battery is fully charged. The performance of Li-Ion batteries is
particularly limited in temperatures below 32°F (0°C).
The following list provides guidelines that you can follow:
• When the operating time (talk time and standby time) is noticeably
shorter than normal, buy a new battery.
• Use the battery only for its intended purpose.
• Never use any charger or battery that is damaged and/or worn out.
• Dispose of batteries according to local regulations (for example,
recycling). Do not dispose of as household waste.
• When you disconnect the power cord of any accessory, grasp and pull
the plug, not the cord.
