How to backup from a 16 GB iPhone to a 8 GB iPhone?

My son has a 16 GB iPhone 4s he now has a new 8 GB 5 c. How do we backup and restore all his contacts, music, pics, apps, etc from 16 to 8 GB? I'm getting him to delete old pics and apps right now. Will that help?

Look on the phone and see what is taking up all the space. Then decide what you need to get rid of.

  • What happens when I backup my iphone with my iphone I'm currently in vacation and my iphone lock button stopped working so I'm going to the aple store to get it fixed and i don't have a backup so i was wondering what happens when you backup your phone from your phone. Like in the setting of the iphone when you go to iCloud it asks if you want a backup. Does this mean that all my stuff will go to my computer back home? Even though I don't have a Mac?
  • Is there a way(without computer)to move my texts from my iPad to my IPhone? ICloud backup? Had to restore phone to last backup and lost texts? Hi, yesterday I had to reset my phone (IPhone 8 plus) to factory default and restore it to its last backup (April 15th). I also have an iPad mini, which everything is Synced. I got everything back on my phone (up to date) except my text messages. I'm not able to access my computer right now and have read you can get them back my backing up you messages to ICloud. Is there anything I can do to get them back on my phone (they are still on my iPad mini), without using my Mac?
