I originally had my band set up with my iPhone 6 but got tired of constant BT connectivity issues so I bought a cheap WP to experiment with, a Lumina 635 for $45 on Amazon. I now no longer have BT connectivity issues but the data never automatically syncs like it did on my iPhone, I have to manually sync data every time. The iPhone synced like every hour on its own so when I opened the Microsoft Health app I wouldn't have to sync data manually like I do now. Is it normal for windows phones to only sync manually?
