Maximizing battery life
You can increase the life of your Treo 650 battery by following a few easy
guidelines. Remember that battery life depends on how you use your Treo device.
Charge your Treo 650 whenever you're at your desk, or charge it overnight
each day. The Lithium Ion (Li-Ion) battery has a much longer useful life when
it is topped off frequently, rather than charging it after it is fully drained.
The wireless features of your Treo 650 (phone, email, messaging, and Web)
consume more power than its organizer features. However, if you spend a lot
of time using the camera (if included), games, media players, eBooks, or other
Palm OS® applications, keep an eye on the battery level and charge when
necessary.
If you don't plan to use the wireless features on your Treo 650 for awhile, you
may want to turn off your device (see "Turning Your Device's Phone On and
Off" on page 35). You can forward calls to a different number or let all calls be
picked up by voicemail (see "Call Forwarding" on page 173).
As with any mobile phone, if you are in an area with no wireless coverage,
your Treo 650 searches for a signal, which consumes power. If you cannot
move to an area of better coverage, you may wish to temporarily turn off your
device's phone (see "Turning Your Device's Phone On and Off" on page 35).
Turn down the screen brightness (see "Adjusting the Brightness" on
page 147).
Decrease the Auto-off setting in Power Preferences (see "Power Preferences"
on page 155). This turns off your screen automatically after a shorter period
of inactivity.
