Charge the battery
Your battery has been partially charged at the factory, but you may need to recharge
it before you can switch on your phone for the first time.
If the phone indicates a low charge, do the following:

You do not need to charge the battery for a specific length of time, and you can use
the phone while it is charging.
If the battery is completely discharged, it may take several minutes before the
charging indicator is displayed or before any calls can be made.
Tip: You can also use a compatible USB charger to charge your battery.
