58 The Basics
To check the battery charge level
From the Home screen, press the Menu Key and touch Settings
> (scroll the screen up) > About phone > Status.
The battery status (charging, discharging) and level
(as a percentage of fully charged) will be displayed at the top of the
screen.
To monitor and control what uses the battery
The Battery use screen allows you to see which applications are
consuming the most battery power. Information on this screen allows
you to identify downloaded applications you may want to turn off when
not being used, so you can get the most out of your battery power.
From the Home screen, press the Menu Key and touch Settings
> (scroll the screen up) > About phone > Battery use. The screen
will display battery usage time. Either how long since last connected
to a power source, if connected to a power source, and how long you
were last running on battery power.
The list of applications or services using battery power are displayed
in order of energy used, from greatest amount to least.
Touch an application in the Battery use screen to see the details
about its power consumption.
Different applications offer different kinds of information, and they
may even include buttons that open settings you can use to reduce
power consumption by that application.
