I want to do a clean install of my iPhone to hopefully improve my battery because it's draining quite fast ( it lost 20% on standby for 3 hours) but I want to set it up as a new phone for a few days just to see how it is, and then would like to put my pictures, music, contacts and notes on it. I want to know is there any way I can put them on, but only them? Also would this bring back 'problems' that I'm having now because it's like restoring them?
