Connect the charger to the phone
Open the cover on the left side of the phone.
Connect the charger to the phone socket and to a wall socket.
When the coloured section of the battery icon is moving, charging is in progress.
End charging
When the battery is fully charged, you can remove the charger from the wall socket and the phone.
When the phone is turned on, you can always see the battery power level. The bigger the coloured section of the battery icon, the more power.
