Hello, how are you? So, my 5s delivery is scheduled for today. When it arrives I will do a full iTunes encrypted backup of my 5 to restore to the new 5s. My question is what to do with the 5s first when I take it out of the box. Should I plug it to the wall charger disconnected and let it charge fully? Should I plug it in to the computer and start the setup? What is the better procedure in regard to the battery? Thanks. Cheers!
