The reality is that Apple can't fit all the features (e.g. bright colour screen) in a watch AND have a battery big enough for 7 days of juice. It's just not physically possible. They could make the watch super chunky but then almost nobody would buy it.
Everyone wants long battery life but it's not that simple. If the tradeoff is having a huge, ugly watch then most people opt to simply charge daily like we already do for our phones.
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.
