The battery is a sealed unit with no serviceable parts. Don’t
attempt to open the case.
Don’t dispose of a battery in a fire! Dispose of used batter-
ies in accordance with local regulations. Recycle!
Using your phone near the network’s base station con-
sumes less power. Keeping the antenna fully extended
whenever possible maintains the connection to the net-
work with less power.
Your phone switches itself off if the operating temperature
of your phone exceeds 158°F/ 70°C. Also, it switches off
after 12 hours if connected to a Compact Handsfree Car
Kit.
When the battery charge is very low, your phone reduces
the power at which it transmits radio signals to extend the
talk time. This may affect the quality of calls.
In some vehicles, the ignition must be on in order to charge
your phone with the Mobile Charger.
