MAXIMIZING BATTERY LIFE

CHAPTER
Unauthorized batteries cannot power your
Centro. Only a battery approved by Palm
will wake up and power your Centro.
• You can buy an extra battery as a spare
for long plane trips or periods of heavy
use. To purchase batteries that are
compatible with your Centro, go to
att.com/wirelessaccessories
or visit
your local AT&T store.
• Charge your Centro 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.
• The wireless features (phone, email,
messaging, Push to Talk, and web) and
media features (camera, media players,
eBooks, and games) of your Centro
consume more power than its organizer
features. Speakerphone usage also
consumes more power than using the
earpiece. If you use the wireless,
speakerphone, and media features
often, keep an eye on the battery icon
and charge when necessary.
• If you don’t plan to use the wireless
features on your Centro for a while, turn
off your phone (see Turning your
Centro™ smart device on and off) and
let all calls be picked up by voicemail.
• As with any mobile phone, if you are in
an area with no wireless coverage, your
Centro searches for a signal, which
consumes power. If you cannot move to
an area of better coverage, temporarily
turn off your phone. While your phone is
off, you can continue to use the
nonwireless features of your Centro.
• Turn down the screen brightness (see
Adjusting the brightness
).
• Decrease the settings in Power
Preferences and turn off Beam Receive
(see Optimizing power settings
).
• Turn off the Bluetooth
®
feature if you’re
not using it. See Connecting to a
Bluetooth
®
hands-free device.
