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.
