I beg to differ. There are ways to improve battery life in Smartphones and increase their life from 1 day to up to 4 days (by removing all power draining apps and adjusting settings differently). I know this would be hard, but this is Apple. I would assume that if anyone, they should be able to deliver. This would be what I would call a real revolution. Give us a smartwatch that can be charged on weekends and is waterproof.
