OK, my iPhone 6 is draining the battery at an alarming rate. I took it to the Apple store and they couldn't diagnose a problem with my battery (got it on launch day), but they swapped out the entire phone anyway. Well, the battery is STILL draining. Anyway, I want to do a clean wipe of my phone (instead of doing another iTunes restore) and start from scratch, but how can I retain all the data from my Apple Watch? If I unpair my Watch or try to repair it, it will setup it up as a new watch, right? And it will have to restore from a backup that's stored on my iPhone (which wouldn't be there if I wipe it to start from scratch). So how do I go about saving all of my achievements and data on my watch? Or am I screwed?
