Battery and power management

Your device has an embedded battery. 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.
