When to Charge the Battery

When the battery is weak and only a few minutes of
operation remain, the device sounds a warning tone at
regular intervals.
In this condition, your device conserves its remaining
battery power by dimming the screen.
When the battery level becomes too low, the device
automatically turns off.
► For a quick check of your battery level, view the
battery charge indicator located in the Status Bar
of your device's display. A solid color ( ) indicates
a full charge.
You can also choose to display a percentage value.
Viewing a percentage value can provide a better
idea of the remaining charge on the battery.
