What am I missing?
The patent in question, if it’s valid, would have expired several years ago. The fact that it’s everyday technology today is pretty normal considering how fast technology advances. Ordinary toilet rolls were also a patented invention and there’s nothing in the law that says a patent has to a complicated solution to a problem.
iTunes was the first shipping product that ever actually did what’s described in the patent… and the person who ran the iTunes department that “invented” this feature was previously a subcontractor working for the guy who holds the patent - he was literally paid to implement what the patent described and then Apple poached him and he continued the work at his new job without any patent license.
I don’t support patents and never will, but if there was ever a case for clear infringement then this is it. It’s already been to court and apple was found guilty of patent infringement… only to have an appeals court overturn the decision in pretty questionable circumstances.
I’d guess it was the small battery in the watch. A lot of features on Apple’s smartwatch cause serious battery life problems unless they can be offloaded to your phone at least most of the day.
For example if you have the weather conditions on your watch face… the watch can lookup the weather but it generally will ask your phone to do that. Stuff like that is a lot easier if you control the phone operating system and aren’t just running an app.
… for example if you never launch the weather app on your phone, both Android and iOS will reduce it’s ability to drain the phone’s battery by running in the background. Apple makes an exception to that rule for weather apps where the user has a widget an Apple Watch face. How could the Android battery management systems know what widgets are on your Apple Watch?
