Hello all, so I'm getting the iPhone 7 Plus when it comes out, and I'm trying to decide whether to set up as new, or restore from a backup. I've always usually done the restore thing using iTunes, and I've heard that maybe it impacts performance by bringing "junk" over to the new device. Is this true? Does restoring from a backup on a brand new device affect performance at all? Is it better to just setup as new? Or is it fine to restore without any effects like this?
