19 hours is not exceptional. At all. And the time it takes to charge is irrelevant if you're not in a place you can charge it.
Unlike your phone, it will require its own dock to charge. That means if you're stuck in an airport for 20 hours, your watch isn't getting charged. it means that this product is going to be a non-starter for many people who know they are frequently away from home base for more than a day.
The same does apply for other smartwatches too who have the same < 1 day battery life.
I was just recently on a european trip. My flight from Amsterdam to Copenhagen got cancelled. My phone battery died. I was stuck in the airport then running around amsterdam for an additional day with no hotel or home to plug anything in. My watch though, kept me going with the time. I never had to think about it. thats the purpose of a good quality watch. that and fashion.
neither the Apple watch is going to hit. This is going to put it into the same category as every other 1 day smart watch maker. Your average geek will wear it. but thats about it.
The Apple Watch doesn't need its own
dock to charge, it will come with a convenient USB-MagSafe charging cable, that you can plug into any powered USB port (very many flights have them on their seats nowadays) or onto the wall socket, which, and I confess, it's difficult for me to believe that you did not find at some of the biggest international airports in Europe, with the included USB charger or with your iPhone's charger. (If your flight is canceled, the airline generally offers you lounge access or hotel. Try it the next time, although I hope it doesn't happen to you again).
Now logically thinking, you're going to use the Watch as an accessory to the iPhone: You'd be mostly reading and actioning notifications and checking the time. I don't think this will cause battery drain, as opposed to if you start playing games on your Watch.
It's a watch. It's on your wrist. With the limited battery technology available today for commercial use, it can only fit a tiny battery. I'd say around 300mAh? (For reference comparison the iPod Shuffle has 200mAh and the iPhone 6 has around 1800mAh).
Now if you're a frequent flyer or a heavy traveler, you could easily get a portable external USB battery charger, eg. from JustMobile, Mophie and the like. These are light, small and very fairly priced nowadays. So you have a 2400mAh USB battery charger for ~$17, and it can easily charge your Watch's battery
over 7 times.
You seem to be completely ignoring people who actually.. kinda do. What I mean by that is what about the frequent traveler. Many journeys across the globe can take upwards of 24 hours between catching flights, the flight itself lay overs etc. Point is, you can find yourself many times in situations where it is not realistic or convenient to pause to tie your arm to the closet power plug you can find to charge your watch, all the while staring at said watch in desperation as you see your boarding time drawing near.
That's just one example. Long bus trips is another.. etc etc.
⬆️ The same as above.
