TIP
You can also charge your phone battery by connecting your phone to your
computer using the USB cable. Charging this way takes much longer than using
the AC charger. Do not, however, connect the Palm
(sold separately) to your computer.

Maximizing battery life
Battery life depends on how you use your phone. You can maximize the life
of your battery by following a few easy guidelines:
•
Charge your phone whenever you can. Charge it overnight. The battery
has a much longer useful life when it is topped off frequently than when it
is charged after it is fully drained.
•
Set your screen to turn off automatically after a shorter period of inactivity
(see
Set the interval for turning the screen off
•
Keep your battery away from direct sunlight and other sources of heat.
Temperatures over 113 degrees Fahrenheit (45 degrees Celsius) can
permanently reduce the capacity and life span of any lithium-ion battery.
•
As with any mobile phone, if you are in an area with no wireless coverage,
your phone continues to search for a signal, which consumes power. Turn
off your phone if you are outside a coverage area (see
services off (airplane
mode)). You can forward calls to a different number
or let all calls be picked up by voicemail (see
•
The fewer wireless connections you have, the less power is required of the
battery. Turn on airplane mode when you don't need to be wirelessly
connected. Airplane mode turns off your connection to the AT&T
network, and it also turns off Wi-Fi and Bluetooth. You can turn on Wi-Fi
(see Wi-Fi) and Bluetooth (see
Bluetooth
when airplane mode is on.
•
If you set up an email account in the Email application, set the interval to
automatically download email to every two hours or less frequently (see
Enter advanced account
settings).
•
Lower the screen brightness (see
•
Use a Wi-Fi connection to download system updates and applications
from App Catalog (see
Update the software on your phone
Catalog to shop for new
applications). Downloads occur faster over Wi-Fi
than over an AT&T data connection, and thus use less battery power.
•
Keep in mind that frequent use of instant messaging (IM) can reduce
battery life. Sign out of your IM account when you are not using it (see
Sign out of an IM
account).
•
Shut down the phone completely when you won't be using it for an
extended period of time (see
