Battery usage time is displayed at
the top of the screen. It tells you
how long it has been since you
last connected to a power source
or, if connected to a power source,
how long you were last running
on battery power. The body of the
screen lists applications or services
using battery power, from greatest
amount to least.

operating system
If you install and use an open source
operating system (OS) on your phone
rather than using the OS provided by
the manufacturer, your phone may
malfunction.
