Hi

If you have iCloud backup turned on when you charge an iphone it should be automatically backed up to iCloud Over your wifi.

When you get iPhone repaired at Apple store

Set back up over your wifi when it asks if you want to use iCloud backup Say yes to get your apps and data back this will only work if you had iCloud backup turned on.
