Apple Watch will likely require daily charging, Cook says
As part of his interview at the WSJD Live conference on Monday, Apple's Tim Cook said he anticipates Apple Watch users are likely going to need to charge the device daily because they will use it so much.

In discussing the upcoming smartwatch device, Cook was expectedly tight-lipped about specifications, but did tell Wall Street Journal managing editor Gerry Baker that he believes Apple Watch will last about a day.
"You're going to wind up charging it daily," Cook said.
The comments are in line with previous estimates, as well as Cook's own predictions from the Apple Watch unveiling in September. Aside from daily charging, the executive declined to discuss exact specifications, availability or price.
Baker did ask about Apple TV, with Cook saying Apple has big plans for the television market, which he calls a "time capsule."
"We're living in the 1970s," Cook said about the current TV user experience. "There's a lot to be done in this area. What we'll do I won't be so clear."
The Apple chief lauded HBO's recent decision to break off a standalone streaming service, but would not elaborate on Apple's future plans for the living room. The Cupertino tech giant has long been rumored to be working on a new Apple TV set-top streamer with deep cable television integration, but negotiations with major providers reportedly stalled. Some believe the new hardware will feature motion control capabilities derived from Apple's PrimeSense acquisition.

2 out of 3 (the iPhone 6 and 6 Plus) ain't bad.
"You're going to wind up..."? Clever thing to say about a watch, Tim.
What about charging your watch with wrist movements?
I don't think kinetic charging is even close to viable in even a 7 day battery. I'd estimate that you probably need to have a battery that can last months before kinetic energy from every day motion would be enough to keep it charged.

A watch band where the surface was almost entirely solar cells might help. Mechanical systems deliver a lot less energy. A Citizen eco-drive watch can go more than 6 months on about an hour or so of exposure to direct sunlight. A Seiko Kinetic watch has to be shaken nearly every day. I had a conversation with an employee in a jewelers and he complained it was a chore to daily take the kinetics out of the window display and shake them for a while and then put them back, while the Citizens next to them just purred away smug in their superiority.
Rumors are that Apple looked at different ways of charging (like solar) but they weren't having success. I don't think most people will have an issue taking the watch off to charge before they go to bed. And I'm sure Apple is constantly working on Improving battery life. I still think one of the reasons ?Watch isn't coming out until next year is it isn't yet ready for prime time, especially from a software standpoint. There's a reason why watches shown to the media were running demo software In a loop. My guess is Apple will low ball battery estimates so people end up getting better battery life than advertised.
Taking a watch off is a sure way to lose it. I've gifted far too many watches to hotels to count. For some reason I can remember everything else. Because I don't always wear watches I can easily forget them when I do.
I take them off though because I don't like sleeping with watches, as they can hinder circulation. I don't ever buy watches but every two christmases someone gets me one.
Bottom line is that Cook has been regurgitating that same line for years since Jobs said it with no progress to show. What is he waiting for?
The iWatch still stirs my excitement. I am willing to have it charged everyday should it proved to be worthy.
I think ?Watch will establish a new sweet spot for 21st century watches.
Since my first iPhone I stopped wearing watches. Couldn't ever justify the extravagance of a Rolex or Movado, as much as I've liked their looks, either. As all I've ever wanted from a watch was the time, the display on my iPhone filled the bill.
But now that Apple has designed the ?Watch, I'm looking forward to new functions and purposes for a "wrist-mounted display." The heart-rate monitor will be a welcome bonus, as I've resisted buying a dedicated device for that.
I also like the choices of models and will perhaps upgrade to a gold one, should the ?Watch become an essential in my life.
You know, if it could actually charge by being 'wound' that wouldn't be a such a daft idea. Or even look at the system in a Rolex that 'winds' by using a weight that swings around due to body motion. I'm not suggesting as an alternative to a induction charge but in addition too, as a supplemental charge.
EDIT: I see Mr. O already suggested this.
looking at the pic the fit and finish compared to all the other "smartwatches" isn't even close.
The only disappointing element in that is that you won't be able to use it as a sleep tracker, but given its cost I'm not sure I would have anyway. That being said, I charge my iPhone and iPad nightly, so why not add a third device?
Google nexus 6 phone can get 6 hours with a 15 min charge time (has a 3,200 mAh battery)
