My wife and I both got Apple Watches at the same time. My battery is completly flat (10%) in hours whole hers is still at 60%+. She seems to use hers more than I do. My iPhone 6 battery now seems to go on for several day however. I have tried a reset, reinstall from backup repair and as yet no improvement. This is what apple support suggested. Have I got anything switched on inadvertently or a mad power consuming app munching all my power secretly in the background? Anyone got any ideas?
