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, tap the Apps Key
phone > Battery > Battery usage. The top of this screen displays a usage
graph and below it, battery usage times. It lists all of the applications or
services using battery power from the greatest amount of energy used to
the least amount.
Tap an application or service in the Battery use screen to see the details
about its power consumption, including either how long since last
connected to a power source or how long you were last running on
battery power. Different applications or services offer different kinds of
information, and they may even include options to modify the settings so
you can reduce power consumption by that application.
Battery saver mode
If the battery charge level drops to low levels, the phone automatically
activates Battery saver mode (if set to On) to conserve battery power until
you can recharge it.
From the Home screen, tap the Apps Key
Battery saver.
From the Battery saver screen, select to activate Battery saver mode
immediately, or when the charge drops to 5% or 15%. If you turn off
Battery saver mode, when the battery charge becomes low, a
notification prompts you to turn it on.
