USB Storage
Your phone's micro USB port lets you connect to an (optional purchase) external device such as a
speaker or portable battery charger. For stage data devices, use unmount the device before
disconnecting to make sure no data is lost.

From home, tap Apps

BATTERY SETTINGS
Your phone is equipped with a battery that allows you to recharge it before it is fully drained. Monitor
your phone's battery usage through this settings menu. View which functions are consuming your
battery's charge and at what percentage.
Warning: Don't try to remove or replace the battery yourself—doing so may damage the battery and
could cause burning and injury. If your phone becomes unresponsive, try a reboot—press and hold
both the Power Key and the Volume Down Key until the screen goes dark, and your phone restarts.
Note: Searching for service, vibrate mode, browser use, and other variables may reduce the
battery's talk and standby times.
