Charging the battery
The phone battery is partly charged when you buy the phone. It may take a few minutes
before the battery icon appears on the screen when you connect the phone to a power
source. You can still use your phone while it is charging.
The battery will start to discharge a little after it is fully charged and then charges again after a
certain time. This is to extend battery life and may result in the charge status showing a level
below 100 percent.

Maximising battery performance
You can use the following methods to improve your battery performance:
•
Decrease the brightness of the screen.
•
Charge your phone often. The battery lasts longer if you charge it frequently.
•
If you are in an area with no coverage, your phone repeatedly scans for available networks.
This consumes power. If you cannot move to an area with better coverage, turn off your
phone temporarily.
•
Turn off 3G, Bluetooth™ wireless technology and the Wi-Fi™ connection when you do not
need these functions.

performance.
SIM card
The SIM (Subscriber Identity Module) card, which you get from your network operator,
contains information about your subscription. Always turn off your phone and detach the
charger before you insert or remove the SIM card.
PIN
You may need a PIN (Personal Identification Number) to activate the services and functions
in your phone. Each PIN digit appears as *, unless it starts with emergency number digits,
for example, 112 or 911. You can call an emergency number without entering a PIN.
