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.
