Charging Your Phone 
Your phone’s battery should have enough power for the 
phone to turn on, find a signal, and make a few calls. You 
should fully charge the battery as soon as possible. 
If the battery is low, there will be a pop-up message on the 
screen. As you charge your phone, the lock screen will show 
you the exact battery level on the status bar.
