Yesterday I got my smashed iPhone screen repaired at the Apple Store and they ran some diagnostics on it as I complained about the battery life. They told me that I had 24 crashing apps, and a few other discrepancies. I've basically always restored my iPhones from a backup so I'm now about 5 phones deep in restored iOS installs, and I'm guessing it's causing my battery issues. The Apple genius said as much, and if I restored my iPhone to factory, I'd see a big improvement as the battery's condition was very good. My question is regarding contacts. I don't have a problem re-installing apps, or starting with zero pictures etc again (they'll be backed up on my Mac) but I really can't be bothered to enter each contact manually. Is there any way of getting my contacts over without it bringing back any of these supposed problems that are causing less than satisfactory battery life?
