As the battery is being charged, the notification LED shows a solid red 
light when the battery is being charged. The light turns to solid green 
when the phone is fully charged.
When you charge the battery while the phone is on, the charging 
battery icon (   ) is displayed in the status bar of the Home screen. 
After the battery has been fully charged, a full battery icon (   ) will 
be displayed in the status bar of the Home screen.
Only the AC adapter and USB sync cable provided with your phone must be 
used to charge the battery.
Do not remove the battery from the phone while you are charging it
