I meet a guy today to sell my iPhone 6 for $600. Not a bad deal on a one year old phone. I'll pay Verizon's ETF and then go to the same store in a week to camp out for the iPhone 6S. That means my Apple Watch will be without any link for 9 days. Shame it won't connect to my iPad for the time being. Anyway, I was going to just put the Apple Watch in Airplane mode so health and motion are still captured but my battery doesn't die searching for the iPhone Question: Will the watch capture health data and sync it to my new iPhone once it's restored from iCloud backup? How much data will be stored? Do you think the watch can save a week of my movements and heart rated? I'd like all of it to be synced to Health.app but I don't know how far back the watch will wait for an iPhone to sync with? Thanks.
