2.3.4 Charging the Battery
Before charging the battery, ensure that it has been properly installed in your phone.
1. Connect the USB cable that came with your mobile phone to the charger.

charging, plug the charger into an electrical outlet.
If you charge your mobile phone while it is powered on, the battery icon on the

your mobile phone is fully charged.
2.3.5 Important Information About the Battery
• If the battery has not been used for a long time, you may not be able to power on
your mobile phone immediately after you begin charging the battery. Allow the
battery to charge for a few minutes with the phone powered off before attempting
to power the phone on.
• As it ages, the battery's performance will degrade, in particular it will not hold
charge as it did when it was new. When the battery life becomes noticeably shorter
than usual after being charged properly, replace the battery with a new one of the
same type.
• Using data services increases the power consumption of the phone and will
therefore reduce the length of time that the phone can be used between battery
charges.
• The time required to fully charge the battery depends on the ambient temperature
and the age of the battery.
• When the battery power is low, the phone will alert you and display a message.
When the battery power is almost exhausted, your phone will power off
automatically.
