Battery and power management
You can keep track of your battery consumption and see which applications are using
the most power. You can also view an estimate of how much time is left before your
battery runs out. The estimated battery time is based on your most recent usage pattern.
To make the battery last longer you can use one or more battery saving modes, which
include STAMINA mode, Low battery mode, Location-based Wi-Fi®, and Queue
background data mode. Each mode works in a different way and controls several power
consuming functions on your device.

Improving battery time using STAMINA mode
STAMINA mode turns off functions that you don't need when your device isn't in use.

several power consuming applications when your device is powered on but the screen is
inactive. So you save the battery but can still receive phone calls, texts and multimedia
messages as they come in. You can also exclude individual applications from being
paused by STAMINA mode. Once you activate the screen, all paused functions are
resumed.
